Definitions
- the present invention relates to shoe machinery and more particularly to shoe upper shapers designed to form and shape shoe uppers, and to smooth the backs and sides thereof.
- one of the objects of this invention is to so shape the finished upper as to eliminate such faults, and to impart a finish to the quarters of the shoes, by smoothing out the back seams and lining, and setting up the quarters.
- the herein described invention eiects improvements in the art by conforming and modifying shoe Shapers of the type described in the United States patents to Ruff, et al., No. 1,334,968, of March 30, 1920, and to Freeman, et al., No. 1,720,891 of July 16, 1929.
- a plurality of forms and shaping members on a rotatable head or turret there is provided a plurality of forms and shaping members on a rotatable head or turret.
- each of the shaping forms is provided with a heating unit, and the arrangement is such that the shoes or upper parts may remain within the shaping mechanism a more evenly regulated time than has been obtained with the use of a single form and shaping unit.
- the ecient and novel operation with accurately controlled temperature and pressure eliminates the possibility of ruining the iine leather of shoe uppers by too great exposure to heat or pressure in the shaping operation.
- the forms are so designed, and arranged on the turret in such a manner that when a shoe 40 element is once placed on a form, it will be supported thereon in proper position for shaping without the assistance of an operator.
- the series of complementary shaping forms are movable in unison, with the turret, such that the movement of one unit away from theA operator, brings the next unit into operating position, and the operator placing shoes on the forms need not move out of position, thereby saving time and labor over that required to feed a plurality of individual pressing units having no cooperating relation.
- the electrical mechanism is preferably provided with a stationary rheostat connected by push pin sockets to stationary brushes which are in contact with rings. through ⁇ which electric current may passto individual heating units in the respective shaping forms.' This construction makes a standard head or turret together with its electrical' connections available for any desired number of shaping units without additional changes in structure.
- ⁇ A specific object of this invention is the provision of improved means for shaping shoe uppers on forms, cooperative with elements which 15 apply localized pressures'to the mounted shoe uppers with ya constant force, applied during a complete cycle of rotation of the turret head of the machine.
- shoe element is employed to include all classes.l
- An important object of the invention is the application and regulation of sufficientv pressure along the sides and backs of shoe uppers partico ularly, to effect a permanent shape, together with the application andmaintenance of such pressure by power actuated means.
- An improved clamping or pressing mechanism is provided inconjunction with the form upon which the vshoe is placed, consisting of vclamping members which may be interconnected and movable to apply pressure in a plurality of directions, e. g., longitudinally of the shoe element, and transversely thereof from diierent sides, this mechanism, however, utilizing the same broad principle of operation as illustrated in Patent No. 1,720,891.
- a unique cushioning mechanism is provided to equalize pressures applied to the opposite sides of the shoe element, such that the pressures against one side will automatically equalize with those applied to the other side of the shoe without, in any manner, disturbing the pressures applied against the back or heel portion of the shoe element.
- clamping members interconnected in such a manner that pressure may be applied along the back seams of the shoe element as well as about the sides and quarters
- clamping and pressing members whichare not interconnected and in which the pressure-on the back seam may be applied independently from that applied to the sides, or may be eliminated entirely if found desirable. Such an arrangement is illustrated herein.
- a still further object includes control means effective to permit the application of power to the turret, whereby to rotate the turret a distance equal to the space between any pair of presser-units, and then automatically cut out the power, thus' insuring adequate placement of each unit to the operator.
- various adjusting means will be provided, whereby individual portions of the unit, as well as the unit itself, may be variably positioned to accommodate any operator. 'I'he assembled turret and associated parts are mounted for vertical adjustments to accommodate the height of an operator without any changes in either the electrical equipment or the shaping mechanism.

- a turret 3 has secured thereto or formed integrally therewith, a sleeve 4 about which is adjustably clamped a rsplit collar 5.
- the sleeve 4 which forms a stem or support for the turret 3, has an external diameter equal to the internal diameter ofthe upper portion of the column I.
- the top of the column provides a bearing 6 for the collar 5, whereby, through the medium of the collar the turret is rotatably supported on the column, while at the same time, it may be vertically adjusted thereon.
- a cam member 'I having a single vlow point or notch la., and a continuous upper cam surface 8, is adjustably, but fixedly, mounted exteriorly of the column I below the turret and hence, may be positioned to engage elements carried by the turret, in any position of'adjustment of the turret.
- the cam members 6 As the turret is vertically adjustable, so also is the cam members 6.
- the turret is in the form of a wheel having a series of spoke-like webs 9, the outer ends of which are interconnected for the lsake of strength and rigidity.
- the outer end of each web is formed with a boss ID having an enlarged opening II to receive Va supporting shank of an individual pressing unit, and Va smaller opening I2 therebelow to receivea steadying pin on such u nit, whereby the unit may be rigidly supported on the turret.
- An opening extending through the boss at an angle to the opening I I may serve for reception of a set screw I3 designed to clamp the head in position.
- Leads I4 extend from a pin socket I5 at the linner end vof each opening II through the webs 9 to a commutatorand vconnections indicated generally at I6.
- This commutator and the various electrical connections are generally the same asdisclosed in Patent No. 1,720,891, and need no particular description here. Suffice to say, that the commutator is relatively fixed and makes electrical contact with brushes at the ends of the leads I4 whereby current may pass to the individual heads, while interiorly mounted are pin and socket connections I1--I 8 for detachably connecting a rheostat organization, which may be positioned iiatwise over the upper central part of the turret. Ihis rheostat organization and controls will be housed in a dust excluding casing I9.
- the commutator is carried on a shaft 20 which extends to the base of the column in non-rotatable relation to the column, but which may be adjusted vertically to accommodate adjustments of the turret.
- a projecting lug 23 to which is pivoted a rocker arm 24 terminating at its inner end. ina tapered roller 25 which is positioned to ride upon the cam surface 8 of cam member 1.
- the outer end of the rocker arm 24 is pivoted at 25 to a connecting rod 21.
- a cross head 28 is mounted for free movement on the connecting rod 21 which extends through a, central hole in the cross head of slightly greater diameter than the diameter of the rod 21.
- a spring 30 Between a washer or an enlarged head 29 on the end of the rod 21 and the cross head 28 is a spring 30, whereupon it will be obvious that a downward pull by the o-uter end of the rocker arm 24 will rst tend to compress the spring 38 against the cross head, and thereafter move the cross head downwardly, the rod 21 and the spring 30 forming a cushion joint between the cross head 28 and the rocker arm 24.
- the ends of the cross head are connected to upwardly extending links 33 which run to the head 34 of the pressing and shaping unit proper.
- the head 34 is mounted on a stern 35 which extends slidably into a boss 36 extending from a bracket arm 31.
- a pin and slot connection 38 (Fig. '1) serves to prevent rotation ofthe stem 35 in the boss 36.
- the bracket arm terminates at one end in a hollow shank 39, interiorly of which is positioned an electric plug (not shown),
- the exterior of the shank 39 may be suitably recessed or notched for reception of the set screw i3.
- a steadying pin 48 will enter the opening I2 to prevent relative movement between the turret and the head.
- the outer end of the bracket 31 terminates in a form 43 having an insulated outer face 44, the form being designed to enter and support a shoe element which is to be pressed and shaped, the sides of the form of course, being shaped to the predetermined contour which the shoe element will take.
- Leads 45 extend from the plug in the hollow shank 39 to a heating ele-ment (not shown) internally of the form and are prevented from displacement away from the bracket 31 by an insulating plate 46.
- the form 43 upon which a shoe element will be supported Afor the shaping operation, is rigid with the turret and suitably heated by connections extending from the zommutatorV to the interior of the form and that the head 34 of the'unit; while carried by the bracket 31 is movable or slidable .with respect thereto and with respect to the form 43.
- the links 33 which extend upwardly from the cross head 21- are connected at their upper ends to pivot pins 41 mounted respectively in curved sliding member 48 ywhich move in an arcuate track 49, cut or formed in the head 34.
- Suitable slots 58 arei provided in the head 34 for the pins 41, and a cover plate v34a is utilized to hold the slides 48 in place, as Well as to exclude dirt therefrom.
- each of the sliding members 48 is a shaping or vpressingwing 5I, these wings being interconnected across the upper end of the form by ayflexible strap or contact liner 52 backed by a spring steel band 53 extending downV across the interior faces of the wings 5
- the wings and band are shaped to conform substantially to the shape of the outer faces of the form 43.
- this pad is positioned intermediate the strap 52 and the band 53.
- this pad will extend from the lowermost tip of 4one wing up over the form and down to the lowermost tip of the other wing, over the operating surfaces of both wings 5I
- the flexible strap or contact liner 52 which is detachably held onthe wings by snap fasteners, or any equivalent means, act to secure the pad 54 in 101306.
- the Vwings When the Vwings are actuated toapply pressure against the shoe element or the form,y there will be, in addition to the main application of pressure bythe wings 5I, localized pressures b-y the pad, inwardly against selected portions of the shoe.
- any desired localized pressures may be obtained on the shoe, e.l g., on the extreme edges only of the shoe elementwith or without lesser pressures against other portions of the shoe, or it may be advantageous to apply a localized pressure over a substantial selected area of the side of the shoe, in addition to areas adjacent the upper edges.
- the shoe element may be desired to press one portion of the shoe element by direct engagement with the wings, and another portion by interposition of the pad.
- Thepad need not be extended from one wing to the other over the form, but separate pads may be used for each wing.
- the unit of Fig. 12 may omit the interconnecting portion between the wings 5
- 'Ihe head 34 may be provided with a forwardly extending boss or projection 4I which functions as a positive presser yoperating in a downward direction, and which may be provided with a contaci liner 52b and a pad 54h.
- the wings 5I will be provided with pads 54a and contact liners 52a.
- the operation of this form will be substantially the same as that of the preferred form shown in Fig. 5 in that downward movement of the head 34 will rst produce a contact and application of pressure across the back of the shoe at the top of the form, by the member 4
- continuous contact liner 52 and a continuous pad 54 might be utilized in this modification, in exactly the same manner as in the preferred form.
- Fig. 13 an arrangement is illustrated in which the head 34 might readily be stationary and an upper movable presser member 42 provided thereon.
- This member 42 is suitably connected to an extension of the pins 41 by any convenient anti-friction and lost motion connections and guided for vertical movement. If the head is held in a fixed position, such that the only movements of the pressing means will be obtained through the element 42 and the wings 5I, then the pressures may be applied simultaneously to the several parts of the shoe instead of a pressure rst on the counter portion of the shoe followed by subsequent pressures onthe sides.
- each of the units is provided with a main pressing means, i. e., the wings I, and a pressing means (pad or pads 54) for localizing pressures, which may or may not form a part of the main pressing means.
- a main pressing means i. e., the wings I
- a pressing means pad or pads 54
- Such an auxiliar-y means may be adapted to almost any predetermined contour, made possible by variation in the thickness and shape of the pad and changes in location thereof, whereby pressure may be brought to bear on selected portions of shoe elements, additional to direct pressures applied by the contoured surfaces of the wings and form.
- an adjusting ⁇ screw 55 carried by the head 34 and engageable with a stop 56 on the bracket 31, this screw beingeffective to variably limit the degree of movement permitted the head 34.
- a spring 51 surrounding the screw 55 and stop 56 serves normally to maintain the head 34 in its upward or outer position on the bracket 31.
- a stop 58 may be secured to the bracket 31 to limit upward movement of the head, although this upward movement is limited generally by the rocker arm 24 and associated parts.
- a elo-ng-ated sleeve 60 which rotatably ts about the shaft 20 and within which the shaft 20 may slide vertically.
- the sleeve 60 While rotatable, is not vertically movable but is, however, splined at 6I to the turret sleeve 4, thus permitting vertical adjustment of the turret and sleeve 4 with respect to the sleeve 60, without in any manner affecting unitary rotatable movement of the two sleeves 4 and 60.
- a notched cam 62 Pinned to the sleeve 60 is a notched cam 62 which forms the direct driving connection between -the turret and the driving mechanism in the base portion 2 of the column I, the notched cam 62 providing a direct control for limiting the degree of movement of the turret.
- a motor M may be located in the base portion 2 of the column, or any source of power such as a drive from conventional factory power, may be utilized for operating the machine. Where a motor is utilized, an adjustable bracket B may support same for beltv tightening purposes.
- the motor may be connected by a belt 63 to a pulley 64, which is formed with an integral, elongated hub 65 mounted in a xed boss 66 of the base portion 2.
- a similar boss 61 is located diametrically opposite the boss 66, and a shaft 68 is mounted for limited sliding movement in the two bosses.
- the end of the shaft 68 Which passes through the boss 66 extends freely through the el-ongated pulley hub 65.
- Splined to the shaft is a worm 65, for rotation thereby, the shaft being free to slide longitudinally of the worm.
- the worm is held against endwise movement by a pair of lugs 10 which are cast in the base of the column.
- a worm Wheel 1I Pinned to the sleeve but, of course, independent of the shaft 20 is a worm Wheel 1I, positioned to mesh with the Worm 69.
- a clutch plate 12 which may be of the friction type but which is preferably of a semi-positive type, is rigidly keyed to the shaft 68, such that endwise movement of the shaft causes an engagement or disengagement of the plate with the side face of the pulley 64.
- the shaft 68 will be caused to rotate by the pulley 64, which is constantly rotating, thereby rotating the worm yand worm wheel to rotate the sleeve 60, the sleeve 4 and the turret 3.
- a yoke 1'5 is rigidly secured to this shaft, ⁇ adjacent one end thereof, and an arm 16, terminating in a flanged toe portion 11 is securely xed thereto adjacent its other end.
- the control lever 83 is pivotally mounted on a shaft 84, carried by an'adjustable supporting bracket secured to the base 2.
- the control lever 83 carries a spring pressed, pivoted latch 85 terminating at one end in a hook portion which is located to engage the angle shaped toe Hof the arm 1S.
- the curved underside of the latch rides over a cam finger 81 which'has the ei'ect of lifting the hook end of the latch away from the toe 11 until, at the moment of engagement between the clutch plate and the pulley, the arm 16 is released, to return to its original position under the influence of a spring 88.
- the cam finger 81 is,of course, adjustable to accommodate various conditions.
- a second arm 89 pinned to the shaft 13 said arm terminating in a toe portion carrying a cam roll 99, both arms 1S and 89 being therefore rigidly secured to the same shaft.
- the cam 62 is shaped with a series of notches about its periphery, one notch for each pressing unit carried by the turret head.
- the roller 90 When the turret is stationary, the roller 90 will be positioned within a notch, but when the shaft 13 is rocked under the iniluence of the treadle 89, the roll 90 will be withdrawn from its notch to ride on a high or peripheral surface portion of the cam, as the cam rotates with the sleever.
- the clutch plate cannot become disengaged from the pulley, even though the latch tlhas released the arm 13, due to the cam finger 81, until such time as the cam roll 99 has reached an adjacent notch, whereby it will drop into such notch under the influence of the spring 88 which, pulling the arm 1B in one direction, tends to push the arm 89 in the opposite direction.
- the end ofthe treadle 80 beyond its pivot shaft 19 is projected to form a cam 9
- Relative movement between the rod and sleeve is limited by a pin 95 operating in a slot 96.
- a spring 91 surrounding the rod 93 engages the lower end of the sleeve 94 and abuts a collar 98 on therod. It follows then that depression of the treadle 89 will compress the spring 91, thereby forcing the sleeve 94 upwardly, maintaining the sleeve in such position until compression of the spring is relieved. Release of the treadle acts to release the compression of the spring which is then free to push the rod 93 downwardly, and through the medium of the pin 95 to positively return the sleeve 94 to a lower position as the pin reaches the bottom of the slot 96.
- the cam 1 has its sole low point or notch 'ICL positioned at the front of the machine, thatis atV a point facing the operator, and it is into this notch that the roller 25 on the rocker 24 will ride when the turret comes to rest with a pressing unit ready to receive a shoe element.
- the upper end of the sleeve 94 carries a head 99 (Fig. 1) positioned to engage the arm 24 or the roller 25 when the treadle 89 is depressed,
- the turret will begin to rotate, carrying the roll 25 on to the higher surface 8 of the cam, thus drawing down the pressing wings andstraps .about the form and holding same in such position until the turret has made a com-plete revolution bringing the roll back to the notch again.
- the head 99 will engage an'innerr end of the roller 25 to facilitate the rotary movement of the rocker with respect to the head 99 and the cam.
- depression of the treadle then'produces, first, a downward movement of the wings 5I and 'the interconnecting strap or liner 52 about the heel or counter portion of a shoe element which, of course, is positioned with the toe pointing downward and the sole facing the'operator in the embodiment of the invention shown. Further movement of the treadle will cause an inward movement of the wings toward each other, downward movement being limited by engagement of the liner 52 with the shoe element, and by the stop 56.
- the cam 1, and the operating connections are arranged to continuously compress the shaping wings about the constantly heated forms, with the exception of the one unit which is positioned in front of the operator.
- means may be provided to render a selected' unit, or units, inoperative, as illustrated in Figs, 14 and 15.
- the rocker 24 is replaced by a yoke 2
- Extending from the frame is a finger 3
- the cross bar 32 is mounted in the yoke for yielding movement, being held in position by springs 2
- the mechanism within the column and in the base portion thereof may be dispensed with, and individual unit actuating mechanism, such as disclosed in the aforesaid Patent No. 1,720,891, may be substituted therefor. All that is necessary in this connection would be to secure each of such actuating mechanisms to the lower portion of the Wings 9, and to connect same to the rod 21 at the point 26. Inasmuch as this hand actuating mechanism carries a locking mechanism with each unit thereof, it is unnecessary to utilize the rocker arm 24 and the cam mechanism 1 8.
- the bracket 58 by its engagement with the lug which supports the adjusting screw 55 will still function to limit upward movement of the head 34.
- a form adapted to fit within and support a shoe, said form being shaped to conform to, and to facilitate an operation upon a shoe upper, shaping means for engaging and applying pressure against said form including means for localizing pressures on selected portions of said form, power actuated means for moving said shaping means into and out of engagement with said form, and means automatically operative to maintain the applicationV of such pressures a predetermined length of time.

50 Claims.
The present invention relates to shoe machinery and more particularly to shoe upper shapers designed to form and shape shoe uppers, and to smooth the backs and sides thereof.
No matter how carefully shoes are made, or the uppers of shoes are cut, fittedand lasted, manufacturing processes tendto produce a gaping of the quarters, wrinkling or roughness at the seams, and similar faults dimcult to eradicate afterwards. This isparticularly true when it is considered that the shoe must be removed from the last. Accordingly, one of the objects of this invention is to so shape the finished upper as to eliminate such faults, and to impart a finish to the quarters of the shoes, by smoothing out the back seams and lining, and setting up the quarters.
More particularly, the herein described invention eiects improvements in the art by conforming and modifying shoe Shapers of the type described in the United States patents to Ruff, et al., No. 1,334,968, of March 30, 1920, and to Freeman, et al., No. 1,720,891 of July 16, 1929.
In the improved mechanism, as heretofore, there is provided a plurality of forms and shaping members on a rotatable head or turret. ,Each of the shaping forms is provided with a heating unit, and the arrangement is such that the shoes or upper parts may remain within the shaping mechanism a more evenly regulated time than has been obtained with the use of a single form and shaping unit. The ecient and novel operation with accurately controlled temperature and pressure, eliminates the possibility of ruining the iine leather of shoe uppers by too great exposure to heat or pressure in the shaping operation.
The forms are so designed, and arranged on the turret in such a manner that when a shoe 40 element is once placed on a form, it will be supported thereon in proper position for shaping without the assistance of an operator.
The series of complementary shaping forms are movable in unison, with the turret, such that the movement of one unit away from theA operator, brings the next unit into operating position, and the operator placing shoes on the forms need not move out of position, thereby saving time and labor over that required to feed a plurality of individual pressing units having no cooperating relation.
It is a further object in the improved structure 55 parts that there will be little likelihood of damage being done to the electrical connections inadvertently.
The electrical mechanism is preferably provided with a stationary rheostat connected by push pin sockets to stationary brushes which are in contact with rings. through `which electric current may passto individual heating units in the respective shaping forms.' This construction makes a standard head or turret together with its electrical' connections available for any desired number of shaping units without additional changes in structure.
`A specific object of this invention is the provision of improved means for shaping shoe uppers on forms, cooperative with elements which 15 apply localized pressures'to the mounted shoe uppers with ya constant force, applied during a complete cycle of rotation of the turret head of the machine.
While machines of the type illustrated in the 20 said patents embody structural features capable of carrying out some of the herein recited'objects, theyA are nevertheless essentially hand operated devices, Whereas the instant structure is primarily a power actuated Shaper, although ca- 25 pable of ready adaptation for hand operation should same be found-desirable. n
Among the objects of the present invention is the provision of mechanism acting as a very effective lock against displacement of movable ,30 parts, shoe elements positioned on the machine, etc., during the cycleoffrevolution;
Inasmuch as the structure herein described may be used for pressing, shaping, and forming complete shoes, assembled or unassembled por- 35 tions of shoes, the term shoe element is employed to include all classes.l
An important object of the invention is the application and regulation of sufficientv pressure along the sides and backs of shoe uppers partico ularly, to effect a permanent shape, together with the application andmaintenance of such pressure by power actuated means.
An improved clamping or pressing mechanism is provided inconjunction with the form upon which the vshoe is placed, consisting of vclamping members which may be interconnected and movable to apply pressure in a plurality of directions, e. g., longitudinally of the shoe element, and transversely thereof from diierent sides, this mechanism, however, utilizing the same broad principle of operation as illustrated in Patent No. 1,720,891.
Inasmuch as the thickness of leathers, seams, etc., may vary, a unique cushioning mechanism is provided to equalize pressures applied to the opposite sides of the shoe element, such that the pressures against one side will automatically equalize with those applied to the other side of the shoe without, in any manner, disturbing the pressures applied against the back or heel portion of the shoe element.
While a preferred form illustrates clamping members interconnected in such a manner that pressure may be applied along the back seams of the shoe element as well as about the sides and quarters, it is within the scope of this invention to utilize clamping and pressing members whichare not interconnected and in which the pressure-on the back seam may be applied independently from that applied to the sides, or may be eliminated entirely if found desirable. Such an arrangement is illustrated herein.
Mounting of an entire shaping mechanism and form, as a single unit which may be readily detached from the rotatable turret, is also contemplated, together with the use of selected and interchangeable units, whereby one machine may be' adapted to accommodate different widths and sizes for a run of shoes such as womens, or for interchanging units to t the machine for other runs of shoes such as growing girls, misses, boys, mens, etc. l Conditions may arise where it will be unnecessar'yto utilize all of the units on the' machine for a vgiven operation, and it is an object of the invention to provide means whereby mounted units may be rendered inoperative during the use of other units.
A still further object includes control means effective to permit the application of power to the turret, whereby to rotate the turret a distance equal to the space between any pair of presser-units, and then automatically cut out the power, thus' insuring adequate placement of each unit to the operator.
It is further contemplated that various adjusting means will be provided, whereby individual portions of the unit, as well as the unit itself, may be variably positioned to accommodate any operator. 'I'he assembled turret and associated parts are mounted for vertical adjustments to accommodate the height of an operator without any changes in either the electrical equipment or the shaping mechanism.
To the attainment of the above and other 0bjects which will appear as the description proceeds, reference may be made to the accompanying sheets of drawings, in which:

Fig. 13 is a similar view of still a different modification;
Fig. 14 is a face view of a pressing head unit, illustrating a modified form of connection to the actuating mechanism; and
Fig. 15 is a side elevation thereof.
Although the general principle of operation is quite similar to the disclosures of Freeman Patent No. 1,720,891, mentioned above, improvements have been made by way of variation in the structureV of the individual presser units andin the application of power to operate the turret and the individual heads mounted thereon.
It is to be understood, however, that units of the type illustarted in the machine of said patent, or equivalents thereof, may be utilized if desired, in the machine of the instant invention with but very slight adaptation, other than the substitution of one unit for the herein described pressing heads. y
Referring more specifically to the drawings in which like reference numerals designate like parts, there is generally indicated at I, a column formed with an enlarged base portion 2 which not only provides an adequate support for the entire machine, but serves to house most of the actuating and control mechanism.
The column being hollow, serves to house connections from the actuating mechanism to the driven parts which are supported at the top of the column.
A turret 3 has secured thereto or formed integrally therewith, a sleeve 4 about which is adjustably clamped a rsplit collar 5. The sleeve 4 which forms a stem or support for the turret 3, has an external diameter equal to the internal diameter ofthe upper portion of the column I. The top of the column provides a bearing 6 for the collar 5, whereby, through the medium of the collar the turret is rotatably supported on the column, while at the same time, it may be vertically adjusted thereon.
A cam member 'I having a single vlow point or notch la., and a continuous upper cam surface 8, is adjustably, but fixedly, mounted exteriorly of the column I below the turret and hence, may be positioned to engage elements carried by the turret, in any position of'adjustment of the turret. In other words, as the turret is vertically adjustable, so also is the cam members 6.
As shown vparticularly in Figs. 1 and 2 the turret is in the form of a wheel having a series of spoke-like webs 9, the outer ends of which are interconnected for the lsake of strength and rigidity. The outer end of each web is formed with a boss ID having an enlarged opening II to receive Va supporting shank of an individual pressing unit, and Va smaller opening I2 therebelow to receivea steadying pin on such u nit, whereby the unit may be rigidly supported on the turret. An opening extending through the boss at an angle to the opening I I may serve for reception of a set screw I3 designed to clamp the head in position.
Leads I4 extend from a pin socket I5 at the linner end vof each opening II through the webs 9 to a commutatorand vconnections indicated generally at I6. This commutator and the various electrical connections are generally the same asdisclosed in Patent No. 1,720,891, and need no particular description here. Suffice to say, that the commutator is relatively fixed and makes electrical contact with brushes at the ends of the leads I4 whereby current may pass to the individual heads, while interiorly mounted are pin and socket connections I1--I 8 for detachably connecting a rheostat organization, which may be positioned iiatwise over the upper central part of the turret. Ihis rheostat organization and controls will be housed in a dust excluding casing I9.
The commutator is carried on a shaft 20 which extends to the base of the column in non-rotatable relation to the column, but which may be adjusted vertically to accommodate adjustments of the turret. Below the boss 18 on each of the Webs 9 is a projecting lug 23 to which is pivoted a rocker arm 24 terminating at its inner end. ina tapered roller 25 which is positioned to ride upon the cam surface 8 of cam member 1.
The outer end of the rocker arm 24 is pivoted at 25 to a connecting rod 21. A cross head 28 is mounted for free movement on the connecting rod 21 which extends through a, central hole in the cross head of slightly greater diameter than the diameter of the rod 21. Between a washer or an enlarged head 29 on the end of the rod 21 and the cross head 28 is a spring 30, whereupon it will be obvious that a downward pull by the o-uter end of the rocker arm 24 will rst tend to compress the spring 38 against the cross head, and thereafter move the cross head downwardly, the rod 21 and the spring 30 forming a cushion joint between the cross head 28 and the rocker arm 24.
The ends of the cross head are connected to upwardly extending links 33 which run to the head 34 of the pressing and shaping unit proper.
The head 34 is mounted on a stern 35 which extends slidably into a boss 36 extending from a bracket arm 31. A pin and slot connection 38 (Fig. '1) serves to prevent rotation ofthe stem 35 in the boss 36. The bracket arm terminates at one end in a hollow shank 39, interiorly of which is positioned an electric plug (not shown),
adapted to engage the socket l in the boss Ill,
when the shank is positioned in the opening Il, and secured in position by means o-f the set screw I3 thus supporting the pressing unit in the turret. The exterior of the shank 39 may be suitably recessed or notched for reception of the set screw i3.
A steadying pin 48 will enter the opening I2 to prevent relative movement between the turret and the head.
The outer end of the bracket 31 terminates in a form 43 having an insulated outer face 44, the form being designed to enter and support a shoe element which is to be pressed and shaped, the sides of the form of course, being shaped to the predetermined contour which the shoe element will take. Leads 45 extend from the plug in the hollow shank 39 to a heating ele-ment (not shown) internally of the form and are prevented from displacement away from the bracket 31 by an insulating plate 46. This arrangement of form, heating means and electrical connections is substantially the same as in Patent No. 1,720,891, to which reference may be made for further detailed description thereof.
From the description thus far of the pressing unit it will be evident that the form 43, upon which a shoe element will be supported Afor the shaping operation, is rigid with the turret and suitably heated by connections extending from the zommutatorV to the interior of the form and that the head 34 of the'unit; while carried by the bracket 31 is movable or slidable .with respect thereto and with respect to the form 43.
, The links 33 which extend upwardly from the cross head 21- are connected at their upper ends to pivot pins 41 mounted respectively in curved sliding member 48 ywhich move in an arcuate track 49, cut or formed in the head 34. Suitable slots 58 arei provided in the head 34 for the pins 41, and a cover plate v34a is utilized to hold the slides 48 in place, as Well as to exclude dirt therefrom.
Secured to `each of the sliding members 48 is a shaping or vpressingwing 5I, these wings being interconnected across the upper end of the form by ayflexible strap or contact liner 52 backed by a spring steel band 53 extending downV across the interior faces of the wings 5|. The wings and band are shaped to conform substantially to the shape of the outer faces of the form 43.
A -pad 54 of yieldable material,` such as rubber,
is positioned intermediate the strap 52 and the band 53. Preferably, this pad will extend from the lowermost tip of 4one wing up over the form and down to the lowermost tip of the other wing, over the operating surfaces of both wings 5I The flexible strap or contact liner 52, which is detachably held onthe wings by snap fasteners, or any equivalent means, act to secure the pad 54 in 101306. When the Vwings are actuated toapply pressure against the shoe element or the form,y there will be, in addition to the main application of pressure bythe wings 5I, localized pressures b-y the pad, inwardly against selected portions of the shoe. By varying theshape of the pad, and the shapeof the form,any desired localized pressures may be obtained on the shoe, e.l g., on the extreme edges only of the shoe elementwith or without lesser pressures against other portions of the shoe, or it may be advantageous to apply a localized pressure over a substantial selected area of the side of the shoe, in addition to areas adjacent the upper edges.
Further, it may be desired to press one portion of the shoe element by direct engagement with the wings, and another portion by interposition of the pad. Thepad need not be extended from one wing to the other over the form, but separate pads may be used for each wing.
Various modifications in the head unit will occur to those skilled in the art, and as illustrative of variations from the preferred form above described, reference is made to Figs. 12 and 13,
The unit of Fig. 12 may omit the interconnecting portion between the wings 5|. 'Ihe head 34 may be provided with a forwardly extending boss or projection 4I which functions as a positive presser yoperating in a downward direction, and which may be provided with a contaci liner 52b and a pad 54h.` The wings 5I will be provided with pads 54a and contact liners 52a. The operation of this form will be substantially the same as that of the preferred form shown in Fig. 5 in that downward movement of the head 34 will rst produce a contact and application of pressure across the back of the shoe at the top of the form, by the member 4|, and the wings 5l will thereafter come into engagement with the sides of the shoe element.
If desired the continuous contact liner 52 and a continuous pad 54 might be utilized in this modification, in exactly the same manner as in the preferred form.
In Fig. 13 an arrangement is illustrated in which the head 34 might readily be stationary and an upper movable presser member 42 provided thereon. This member 42 is suitably connected to an extension of the pins 41 by any convenient anti-friction and lost motion connections and guided for vertical movement. If the head is held in a fixed position, such that the only movements of the pressing means will be obtained through the element 42 and the wings 5I, then the pressures may be applied simultaneously to the several parts of the shoe instead of a pressure rst on the counter portion of the shoe followed by subsequent pressures onthe sides.
Hence, it willbe seen that each of the units is provided with a main pressing means, i. e., the wings I, and a pressing means (pad or pads 54) for localizing pressures, which may or may not form a part of the main pressing means. Such an auxiliar-y means may be adapted to almost any predetermined contour, made possible by variation in the thickness and shape of the pad and changes in location thereof, whereby pressure may be brought to bear on selected portions of shoe elements, additional to direct pressures applied by the contoured surfaces of the wings and form.
In order to limit downward movement of the head 34 with respect to the bracket there is provided an adjusting` screw 55 carried by the head 34 and engageable with a stop 56 on the bracket 31, this screw beingeffective to variably limit the degree of movement permitted the head 34.
A spring 51 surrounding the screw 55 and stop 56 serves normally to maintain the head 34 in its upward or outer position on the bracket 31.
A stop 58 may be secured to the bracket 31 to limit upward movement of the head, although this upward movement is limited generally by the rocker arm 24 and associated parts.
When tension is applied tothe cushion arrangement 21-30 to draw the cross head 28r downwardly, the links 33 and members 41 will rst draw the head 34 downward until that portion of the strap 52 which interconnects the wings El engages a shoe element on the form thus resisting further downward movement, the screw 55 and stop 5E being adjusted to regulate the degree of pressure desired at this point. Thereafter the members 41 will partake of a sliding movement in the arcuate track 49 to 'move the shaping wings A5I inwardly towardeach other and into engagement with the sides of a shoe element on the form. v
Obviously, then, a downward pressure will be attained at the back edge of the shoe band; in fact, over as much of the heel portion of the shoe as desired, dependent upon the shape and size of the interconnecting portion of the linery 52, the pad 54 and the spring steel band 53.'
By increasing the thickness of the pad 54 and locating its operating portions nearer to the top of the wings, all of the ldownward pressure of the assembly Vcan be exerted on the curved sides of the shoes, to the exclusion of positive pressure against the back seam of the shoe.
Should one side of the shoe befsomewhat thickerthan the other side, due eitherto variable thicknesses in the leather or the seams, the cross head will rock slightly on the connecting rod 21 due to the fact that the hole through-the cross head is slightly larger than the diameter of the rod 21 Vand thus the pressures applied t0 one side of the shoe will be equalized to those applied to the other side of the shoe. In other words, the
wings will seek their own positions due to the relative movement permitted by rocking of the cross'head.
Referring now particularly to Figs. l, 8, 9, and 11, wherein is disclosed the power actuated mechanism for rotating the turret `and for insuring proper compression of the shaping or pressing means about the form, there is illustrated an elo-ng-ated sleeve 60, which rotatably ts about the shaft 20 and within which the shaft 20 may slide vertically. The sleeve 60, While rotatable, is not vertically movable but is, however, splined at 6I to the turret sleeve 4, thus permitting vertical adjustment of the turret and sleeve 4 with respect to the sleeve 60, without in any manner affecting unitary rotatable movement of the two sleeves 4 and 60.
Pinned to the sleeve 60 is a notched cam 62 which forms the direct driving connection between -the turret and the driving mechanism in the base portion 2 of the column I, the notched cam 62 providing a direct control for limiting the degree of movement of the turret.
A motor M may be located in the base portion 2 of the column, or any source of power such as a drive from conventional factory power, may be utilized for operating the machine. Where a motor is utilized, an adjustable bracket B may support same for beltv tightening purposes. The motor may be connected by a belt 63 to a pulley 64, which is formed with an integral, elongated hub 65 mounted in a xed boss 66 of the base portion 2. A similar boss 61 is located diametrically opposite the boss 66, and a shaft 68 is mounted for limited sliding movement in the two bosses. The end of the shaft 68 Which passes through the boss 66 extends freely through the el-ongated pulley hub 65. Splined to the shaft is a worm 65, for rotation thereby, the shaft being free to slide longitudinally of the worm. The worm is held against endwise movement by a pair of lugs 10 which are cast in the base of the column.
Pinned to the sleeve but, of course, independent of the shaft 20 is a worm Wheel 1I, positioned to mesh with the Worm 69.
A clutch plate 12, which may be of the friction type but which is preferably of a semi-positive type, is rigidly keyed to the shaft 68, such that endwise movement of the shaft causes an engagement or disengagement of the plate with the side face of the pulley 64. When the pulley and clutch are engaged, the shaft 68 will be caused to rotate by the pulley 64, which is constantly rotating, thereby rotating the worm yand worm wheel to rotate the sleeve 60, the sleeve 4 and the turret 3.
Extending through the base portion 2 transversely of the shaft 68 is another shaft 13, supported by a pair of lugs 14 formed in the base portion 2. A yoke 1'5 is rigidly secured to this shaft, `adjacent one end thereof, and an arm 16, terminating in a flanged toe portion 11 is securely xed thereto adjacent its other end.
A stub shaft 19, carried in a suitable bearing on the base portion 2, supports a spring pressed treadle 80, in which is mounted a kick-olf pin El, positioned to engage a lug 82, which forms a part of a control lever 83. The control lever 83 is pivotally mounted on a shaft 84, carried by an'adjustable supporting bracket secured to the base 2.-
The control lever 83 carries a spring pressed, pivoted latch 85 terminating at one end in a hook portion which is located to engage the angle shaped toe Hof the arm 1S.
Depression ofthe treadle 80, and consequent engagement of the pin 8l with the lug 82, will move the latch downwardly and to the right (see Fig. 10), pulling the arm I6 to the right, Vand thereby rocking the shaft 13, which in turn rocks the yoke 15. The ends of the yoke engage a clutch shifting collar 86 secured tothe shaft 68, and movement of the yoke accordingly slides the shaft 68 to bring the clutch plate 12 into engagement with the pulley 64.
As the arm 16 moves to the right under the iniluence of the latch 85, the curved underside of the latch rides over a cam finger 81 which'has the ei'ect of lifting the hook end of the latch away from the toe 11 until, at the moment of engagement between the clutch plate and the pulley, the arm 16 is released, to return to its original position under the influence of a spring 88. The cam finger 81 is,of course, adustable to accommodate various conditions.
In order to insure that the clutch plate maintains a connection between the source of power and the driving mechanism long enough for the turret to move a distance equal to the space between two pressing units, there is provided a second arm 89 pinned to the shaft 13, said arm terminating in a toe portion carrying a cam roll 99, both arms 1S and 89 being therefore rigidly secured to the same shaft. The cam 62 is shaped with a series of notches about its periphery, one notch for each pressing unit carried by the turret head. When the turret is stationary, the roller 90 will be positioned within a notch, but when the shaft 13 is rocked under the iniluence of the treadle 89, the roll 90 will be withdrawn from its notch to ride on a high or peripheral surface portion of the cam, as the cam rotates with the sleever.
Obviously, the clutch plate cannot become disengaged from the pulley, even though the latch tlhas released the arm 13, due to the cam finger 81, until such time as the cam roll 99 has reached an adjacent notch, whereby it will drop into such notch under the influence of the spring 88 which, pulling the arm 1B in one direction, tends to push the arm 89 in the opposite direction.
The end ofthe treadle 80 beyond its pivot shaft 19 is projected to form a cam 9|, adapted to engage'a cam roll 92 carried by the lower end of a push rod 93 which telescopes into a sleeve 94. Relative movement between the rod and sleeve is limited by a pin 95 operating in a slot 96. A spring 91 surrounding the rod 93 engages the lower end of the sleeve 94 and abuts a collar 98 on therod. It follows then that depression of the treadle 89 will compress the spring 91, thereby forcing the sleeve 94 upwardly, maintaining the sleeve in such position until compression of the spring is relieved. Release of the treadle acts to release the compression of the spring which is then free to push the rod 93 downwardly, and through the medium of the pin 95 to positively return the sleeve 94 to a lower position as the pin reaches the bottom of the slot 96.
The cam 1 has its sole low point or notch 'ICL positioned at the front of the machine, thatis atV a point facing the operator, and it is into this notch that the roller 25 on the rocker 24 will ride when the turret comes to rest with a pressing unit ready to receive a shoe element.
The upper end of the sleeve 94 carries a head 99 (Fig. 1) positioned to engage the arm 24 or the roller 25 when the treadle 89 is depressed,
whereupon depression of the treadle and upward movement of the rod 93 will raise the end of the rocker 24 to ,lift the roller 25 out of the notch in synchronism with movements of ,the driving mechanism, which is being released for operation by the Vdepression of the treadle.. The turret will begin to rotate, carrying the roll 25 on to the higher surface 8 of the cam, thus drawing down the pressing wings andstraps .about the form and holding same in such position until the turret has made a com-plete revolution bringing the roll back to the notch again. Preferably, the head 99 will engage an'innerr end of the roller 25 to facilitate the rotary movement of the rocker with respect to the head 99 and the cam.
The general operation is as follows. When a pressing unit is in front of the operator, and the treadle in its normal position,v a roller will be resting in the notch 1a, thus positioning the head 34 in spaced relation to the form, whereby a shoe element may be placed on the form.
Depression of the treadle then'produces, first, a downward movement of the wings 5I and 'the interconnecting strap or liner 52 about the heel or counter portion of a shoe element which, of course, is positioned with the toe pointing downward and the sole facing the'operator in the embodiment of the invention shown. Further movement of the treadle will cause an inward movement of the wings toward each other, downward movement being limited by engagement of the liner 52 with the shoe element, and by the stop 56. At the same time, the rotary movement of the turret is beginning, and the roller 25 which has been raised by the push rod 93 moves on to the high portion of the cam to hold the shaping means tightly about the form which, in the meantime, through the medium of contact with the commutator as the turret rotates, is heated. As soon as the turret has rotated a distance sufcient to bring another unit to the operator with its roll dropping into the notch'la, rotary movement of the turret stops, due to release of the arm 89 from the notched cam 62. The cam 1-8 however, is maintaining the first form in clamping and pressing relation to the shoe. x i 1 The operations are thenrepeated until every unit has been filled, whereupon the rst unit'will have reached the operator and theshoe element thereon will be ready for removal.
Although a turret capable of carrying twelve forms is illustrated in the preferred'embodiment, it will be obvious that any desired number of units may be provided, to suity conditions in an individual shoe factory.
As described, the cam 1, and the operating connections are arranged to continuously compress the shaping wings about the constantly heated forms, with the exception of the one unit which is positioned in front of the operator.
This is perfectly satisfactory so long as shoe elements are in place on the forms, but conditions may arise where it will be unnecessary to utilize all of the units on the machine, and this will result in clamping wings of an unused unit directly against a heated form, without the relief afforded by placement of shoe elements thereon,
-a condition which tends towards injury of the contact liner and rubber pad, by the constant heat.
To avoid such a condition, means may be provided to render a selected' unit, or units, inoperative, as illustrated in Figs, 14 and 15.
In the embodiment of these figures, the rocker 24 is replaced by a yoke 2|, and the rod 21, cross head 28, spring 30 and links 33 are omitted in favor of a frame 22, connected to the pivot pins 41. Extending from the frame is a finger 3| which is suitably notched to detachably engage a cross bar 32, carried by the outer ends of the yoke 2|.
The cross bar 32 is mounted in the yoke for yielding movement, being held in position by springs 2|a, for the purpose of facilitating engagement or disengagement between the finger 3| and the bar 32.
This arrangement, with the yieldable cross bar 32 and a substantially centrally located ringer 3| will permit the wings to secure their own positions, or equalize pressures just as in the arrangement utilizing a cross head 28 and rod 21.
Should it be desired to operate the machine by hand power instead of by the automatic application of mechanical or electrical power, the mechanism within the column and in the base portion thereof may be dispensed with, and individual unit actuating mechanism, such as disclosed in the aforesaid Patent No. 1,720,891, may be substituted therefor. All that is necessary in this connection would be to secure each of such actuating mechanisms to the lower portion of the Wings 9, and to connect same to the rod 21 at the point 26. Inasmuch as this hand actuating mechanism carries a locking mechanism with each unit thereof, it is unnecessary to utilize the rocker arm 24 and the cam mechanism 1 8. The bracket 58, by its engagement with the lug which supports the adjusting screw 55 will still function to limit upward movement of the head 34.
As stated above, the entire unit, including the forming and pressing means, `of said patent might be substituted if hand operation is found desirable. i
The operation by hand is otherwise the same as in the power machine except, of course, that the turret will be moved step by step manually and the pressing Wings and straps clamped against a shoe manually by the actuating mechanism, not shown, but fully described and disclosed in the said patent, and to which reference may be found desirable.
