SOLE-PRESSING MACHINE.

Application filed May 18, 1903.

To all whom it may concern:

Be it known that I, ERASTUS E. WINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Pressing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to sole pressing machines and more particularly to that class of sole pressing machines by which the sole of a shoe is subjected to a rolling pressure between a'jacl: upon which the shoe is supported, and a suitably shaped form. Such machines are now extensively used for leveling the soles of boots and shoes, that is, for subjecting the soles after being permanently attached to the other parts of a boot or shoe to pressure in order to remove any inequalities and to give the proper shape or curvature.

Sole pressing machines by which the sole of a shoe is subjected to a rolling pressure are commonly provided with a plurality of shoe supporting jacks and cooperating sole pressing forms, two jacks and two cooperat ing forms being usually provided. The mechanism for actuating the jacks and forms is arranged to move the jacks alternately from a position at the front of the machine in which shoes can be readily removed t'rom and placed upon the jacks, which position is termed a position of presentation, to a position to cooperate with the forms in pressing the soles of the shoes, which position is termed a position of pressure. In all sole pressing machines which are adapted to exert a rolling pressure upon a sole of a shoe the jacks and forms have been permanently connected to their actuating mechanism, and where a single machine has been provided with two jacks and two cooperating forms it has been necessary to stop the machine with one jack in a position of pressure and the other jack in a position of presentation in order to allow the operator to remove a shoe, the sole of which has been leveled from the jack in a position of presentation and place another shoe thereon. The operator has thus been obliged after having placed a shoe upon the jack in the position of presentation to Wait while this jack is Specification of Letters Patent.

moving into a position of pressure and the other jack is returning from a position of pressure to a position of presentation. During the greater portion of the time that the machine is in operation, therefore, the operator is idle. l urthermore, since the machine is necessarily stopped during the time the operator is employed in removing a shoe from the ack in the position of presentation and placing another shoe thereon, the operator 1s not obliged to keep pace with the operation of the machine, the speed at which the machine is operated being entirely dependent upon the will of the operator.

One of the objects of my invention is to provide a sole pressing machine comprising a plurality of acks and cooperating sole pressing forms and means for actuating the jacks and forms to subject the soles of shoes supported upon the jacks to a rolling pres sure in which the jacks and forms shall be so actuated that the operator will be able to remove a shoe from one of the jacks and place another shoe thereon while another jack and its cooperating form are being moved to level the sole of a shoe and to return the jack to a position of presentation.

With this object in view, a feature of my invention contemplates providing a sole pressing machine comprising a plurality of jacks and cooperating forms with a common actuating mechanism acting to move each jack and its cooperating form when connected therewith, to subject the sole of a shoe supported upon the jack to a rolling pressure, and means for connecting each jack and form to such common actuating mechanism and for disconnecting them therefrom. By providing means for connecting each aclr and form to the common actuating mechanism and for disconnecting them therefrom, one jack is allowed to remain in a position of presentation While another jack is being moved from a position of presentation to a position of pressure and being returned to a position of presentation. The operator is thus enabled to devote his entire time to the replacing of the shoes upon the jacks and is not compelled to wait idly for any of the operations of the machine to be completed. Furthermore, it is not necessary to stop the machine with a ack in a position of pressure and the machine can be so speeded that the time required for removing a shoe from a an; and placing another shoe thereon is that con-' Patented Aug. 24:, 1909.

sumed by the machine in moving a jack from a position of presentation to a position of pressure and returning it to a position of presentation. The operator is thus obliged to 5 keep pace with the machine or allow the machine to remain at restwith the jack in a position of presentation for a noticeable length of time.

I am aware of the fact that it has been proposed to place two sole pressing machines side by side in a single frame, each machine comprising a jack, a cooperating form, and means for actuating the jack and form to subject the sole of a shoe supported upon the 'ack to a rolling pressure, and that it has een proposed to operate these machines alternately, the operator removing a shoe from the jack of one machine and placin another shoe thereon, while the other mac ine is in operation. My invention is clearly distinguished from such an arrangement in that it contemplates the use of a common actuating mechanism for all the jacks and forms, the jacks and forms and their actuating mechanism constituting a single organized machine as distinguished from a number of separate and independent machines.

Sole pressing machines by which a'rolling pressure is exerted upon the sole of a shoe are usually constructed to press the sole of the shoe twice, one pressure being produced by the inward movement of the jack and form, and another pressure bein produced during the return movement of t e jack and form to bring the jack into a position of presentation. It is often found desirable, however, to subject the sole to a greater number of pressures in order to properly beat out or level thesole. In many machines this is accomplished by starting and stopping the machine a number of times without removing the shoe from the jack, and certain machines have been devised by which the jack and form are automatically and continuously moved to produce this result. So far as I am advised as to the state of the art, no means has been provided for varying the pressure exerted upon the sole during the successive pressing operations, whether the sole is subjected to two or a greater number of pressures, and an object of my invention is v to provide means for varying the pressure so as to render the successive pressing operations more effective.

With this object in view a feature of my invention contemplates providing a sole pressing machine comprising a jack, a cooperating form, and means for actuating the jack and form to subject the sole of a shoe su ported upon the ack to a plurality of r0 ling pressures, with means acting automatically to increase the pressure exerted upon the sole of a shoe during successive pressing operations. By providing such means the amount to which the sole is compressed during each pressing operation is automatically taken up and the sole is more quickly and certainly beaten out or leveled. Also t 1e use of an excessive initial pressure which would tend to blacken or otherwise mar or injure the leather is rendered unnecessary as a comparatively light pressure can be first applied and this pressure increased during successive pressing operations. As to this feature of my invention I desire to state that it may be embodied in any form of sole pressing machine comprising a shoe supporting jack and a cooperating form arranged to. subject the sole of a shoe supported upon the jack to a rolling pressure, whether such ma- 30 chine is provided with a single jack and its cooperating form or with a plurality of jacks and forms.

My invention is primarily intended as an improvement upon the well-known Tripp 35 Giant leveler machine Which is illustrated and described in United States patent to Tripp, No. 296,486, April 8, 1884, and the machine which I have illustrated in the drawings accompanying this application as embodying my invention in its preferred form is similar in many respects to the machine disclosed in said patent. In the patented machine the jacks and forms are pivotally mounted and each jack and its 00- operating form is oscillated to exert a rollin pressure upon the sole of a shoe supporte. upon the jack. In the patented machine each ack and form is stopped when the jack is in a position of pressure and also when the jack is in a position of presentation. Inthe machine illustrated in the drawings accompanying this application, each jack and form 1s stopped only whenthe jack is in a position of presentation, mechanism being provided which acts continuously to impart to the jack and form relatively long oscillating movements from and toward the position of resentation and intermediate-shorter oscilating movements. So far as I am advised of the state of the art, I am the first to provide mechanism for so actuating a pivotally mounted jack and its cooperating form and I therefore consider a feature of my invention to consist in providing a sole pressing machine comprising either a single jack and a cooperating form or a plurality of jacks and forms, with such mechanism.

In the machine disclosed in the drawings accompanying this application, the mechanism for actuating the jacks and forms comprises a driving shaft similar to the driving shaft of the patented machine, the direction of rotation of which is reversed in order to reverse the movements of the jacks and forms.

A feature of my invention consists in providing means actin automatically to reverse the direction 0 rotation of the driving shaft, whereby the machine continues in oporation until a jack and form is moved toward the position of presentation and in providing means for stopping the jack and form with the jack in a position of presentation.

Another feature of my invention consists in varying the number of rotations of the driving shaft in each direction whereby relative long oscillating movements are imparted to a jack and form from and toward the position of presentation and intermediate shorter movements.

Other features of my invention consist in certain devices, arrangements, and combinations of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art.

Having thus indicated the nature and scope of my invention, I will now proceed to describe the preferred form thereof illustrated in the accompanying drawings, it being understood that the various features of my invention are not limited to the par ticular machine illustrated nor, except as defined in the claims, are they limited to any particular construction or arrangement of parts.

Referring to the drawings, Figure 1 is a View in side elevation of the complete machine; Fig. 2 is a view in front elevation of the machine shown in Fig. 1 with parts removed; Fig. 3 is a view in horizontal section on the line 33, Fig. 1, and Figs. t and 5 are detail views of the mechanism for reversing and stopping the driving shaft of the machine.

The machine illustrated in the drawings is provided with two ache and two cooperating forms, the aclrs and forms being pivotally mounted and so arranged that when either jack and its cooperating form are oscillated the sole of a shoe supported upon the jack is subjected to a rolling pressure. The means for oscillating the aclis and forms comprises a driving shaft and suitable connections between the driving shaft and the acks and forms. The driving shaft is rotated alternately in opposite directions and the connections between the driving shaft and the acks and forms are such that the direction of the movement of the jacks and forms is changed with each reversal in the direction of rotation of the driving shaft. Means are provided for connecting each jack and its cooperating form with the driving shaft and for disconnecting them therefrom so that one jack and its cooperating form can be operated to level the sole of a shoe supported upon the jack while the other jack and form remain in a position of presentation, that is, in a position which allows the operator to readily remove a leveled shoe from the jack and place another shoe thereon. Mechanism is provided which acts automatically to reverse the direction of rotation of the driving shaft and to finally stop the driving shaft with the jack and form which has been connected thereto in a position of presentation. Means are also provided for automatically disconnecting the jacks and forms from the driving shaft as they reach the position of presentation so that when the machine is at rest both jacks and their cooperating forms are disconnected. Means are also provided by which the number of revolutions of the driving shaft in each direction is varied, whereby each jack and form when connected to the driving shaft are given a long oscillation from a position of presentation to a position of pressure and then a number of shorter oscillations sufficient in extent to subject the sole of a shoe supported upon the jack to a number of rolling pressures and then finally a relatively long oscillation to a position of presentation. In order to vary the pressure exerted upon the sole of the shoe during the successive pressing operations to which the sole is subjected mechanism is provided for forcing the form toward the jack with an increasing pressure during successive oscillations of the jack and form.

Referring to the drawin s 1 indicates arms pivoted at 2 in the upper portion of the machine frame 3 upon which arms the sole pressing forms are mounted.

4 indicates arms pivoted at 5 on the frame of the machine beneath the arms 1 and constructed to receive the shoe supporting lacks. The arrangement of the arms 1 and 4 is such that the jacks and forms mounted thereon subject the soles of shoes supported upon the jacks to a rolling pressure when the arms are oscillated. Toothed sectors 6 are attached to or formed integral with the arms which mesh with worms 7 upon vertical shafts 8 journaled in the rear portion of themachine frame.

Motion is transmitted to the vertical Worm shafts 8 by gears 9 thereupon meshing with a gear 10 on a vertical shaft 11 which is connected by beveled gears 12 with the driving shaft 13. The driving shaft is actuated by pulleys 14 and 15 connected with a suitable source of power so as to be continuously rotated in opposite directions. The pulleys are loose on the shaft 13 and are arrangedto be moved transversely into engagement with clutch members 16 secured to the shaft.

A horizontal shipper rod 17 slides in bearings 18 on the frame and carries split collars 19 engaging annular grooves in the hubs of the pulleys. This shipper rod is moved to the right or left at the proper times during the operation of the machine to bring the ipulleys 14 and 15 alternately into engageiment with the clutch members 16 to reverse the direction of rotation of the driving shaft and is also moved to disconnect both pulleys from the clutch members 16 to stop the machine. The shipper rod is actuated to reverse the direction of rotation of the driving shaft by a cam shaft 20 journaled in the frame of the machine transversely to the driving shaft, and suitable connections be tween the cam shaft and the shipper rod. The dam shaft 20 is intermittently rotated from the driving shaft by a traveling nut 21 engaging a threaded portion of the driving shaft and connections between the nut and the cam shaft. These connections comprise a link 22 which connects the nut with a lever 23 pivoted at 24 to the frame of the machine, a link 25 connecting the lever 23 to a bell crank lever 26 pivoted to the frame of the machine at 27, links 28 connecting the opposite ends of the bell crank lever with distance arms 29 pivoted on the cam shaft 20, pawls 30 mounted upon the distance arms and a ratchet wheel 31 engaged by the pawls fixed to the cam shaft. These connections are so arranged that the cam shaft 20 is intermittently rotated as the nut 21 travels back and forth on the threaded portion of the driving shaft, one pawl 30 being in engagement with a tooth of the ratchet wheel when the nut is traveling in one direction and the other pawl being in engagement with a tooth of the ratchet wheel when the nut is traveling in the opposite direction so that the cam shaft is moved forward a step during the travel of the nut 21 in each direction. A cam disk 32 secured to the cam shaft 20 is provided with a cam groove 33 which is engaged by a stud or roll on a shipper arm 34 pivoted at 35 to the frame of the machine. The upper end of the arm 34 has a pin and slot connection with a collar 36 loosely mounted upon the shipper rod 17. Springs 37 and 38 surround the shipper rod and are interposed between the loose collar 36 and collars 39 fast on the shipper rod. The cam disk 32 is also provided with a series of cam projections 40 upon the opposite face to that in which the cam groove is formed Wl'llGll are arranged to engage a roll or stud on. the lower end of a locking lever 41 pivoted at 42 to the frame of the machine. The upper end of the locking lever is provided. with a slot which receives a pin 43 projecting from the shipper rod 17. The shape of the cam groove 33 and the arrangement of the cam projections 40 are such that during the rotation of the cam shaft 20 the shipper rod is held stationary by the engagement of one of the projections 40 with the stud on the lower end of the locking lever 41 while the shipper arm 34 is being actuated by the cam groove 33 to move the collar 36 to the right or to the left as viewed in Fig. 5 so as to compress one of the springs 37 and 38.

After one of the springs has been com-' pressed 'tllQ'COlltlXlUGd rotation of the cam' shaft moves the projection 40 out of engagement with the stud on the lower end of the her of intermediate shorter oscillations.

locking lever 41 so that the compressed spring is allowed to act to move the shipper rod 17 in a direction to reverse the direction of rotation of the driving shaft.

As I have stated the machine shown in the drawings is provided with means for varying the number of rotations of the driving shaft in each direction in order to impart relatively long oscillations to the jack and form connected to the driving shaft from and toward a position of presentation and a nurjps shown in the drawings (see more particularly Fig. 4) these means comprise a cam disk 44 fixed to the cam shaft provided with a cam groove 45 which engages a roll or stud on one end of alever 46 pivoted at'47 to the machine frame. The other end of the lever 46 is connected by means of an adjustable link 48 to the link 25. The link 25 is connected to the lever 23 by means of a pin assing through a slot in the lever. The s a e of the cam groove 45 is such that during the greater portion of the revolution of the cam shaft 20 the pin in the link 25 is held raised in the slot of the lever At one point in the revolution of the cam shaft 20, however, the pin in the link 25 is held in a lower position in the slot of the lever 23. MV hen the pin of the link 25 is in its raised position it will be seen that a shorter travel of the nut 21 is required in order to turn the cam shaft 20 through a distance corresponding to the distance between two of the teeth of ratchet wheel 31 than is required when the )in in the link 5 is in its lowered position. When the pin is in its lowered position. therefore, the driving shaft will be allowed to rotate through greater number of revolutions before the shipper rod is actuated. The final long oscillation imparted to the jack and form connected to the driving shaft brings the jack and form into a position of presentation, and when they reach this position the rotation of the driving shaft is automatically stopped. To this end the nut 21 is rovided with a lateral cam projection 49 w iich is arranged to engage a detent 50 (see more particularly Fig. 3) and move it into a position to engage a collar 52 fast on the shipper rod 17. The detent 50 is so arranged that during the short traveling movements of the nut 21 it is not engaged by the cam projection 49 but is only engaged at the end of the long travel of the nut toward the left as viewed in Fig. 4. \Vhen the collar 52 of the shipper rod 17 is engaged by the detent 50 the rod is held in a position in which both driving pulleys rotate loosely upon the driving shaft. In order to allow the detent 50 to be removed from the path of the collar 52 when it is desired to start the machine into operation it is mounted upon an arm 51 fixed to a rock shaft 53 which can be actuated from either of two treadles 54 carried by 1n in treadle levers 55 pivoted at 56' upon opposite sides of the machine frame. The inner ends of the treadle levers are connected by means of links 57 (see Fig. 1) to vertical rods 58 mounted in bearings 59 in the frame of the machine and passing through openings in lugs 60 projecting from arms 61 secured to the rock shaft 53. When either rod 58 is raised by de ressing one of the treadles a collar on the ower end of the rod engages a lug 60 and rocks the shaft 53 in a direction to remove the detent 50 from the path of the collar 52 on the shipper rod. The sliding engagement of the rods 58 with the lugs 60 of the arms 61 allows the rock shaft to be actuated by either treadle without moving the other treadle or the rod 58 connected therewith. The detent 50 is normally held in the path of movement of the collar 52 on the shipper rod by means of a coiled spring 62 (see Fig. 3) surrounding the rock shaft 53 and having one end secured to the frame of the machine and the other end secured to the hub of arm 51.

In order to allow either jack and its 00- operating form to be connected to and disconnected from the driving shaft the gears 9 on the vertical worm shafts 8 are mounted to rotate freely thereon and are provided with clutch members 63 adapted to be engaged by clutch members 65 splined on the shafts. (-oiled springs 66 surrounding the shafts 8 and interposed between fixed collars on the shafts and the clutch members 65 tend to move the clutch members 65 into engagement with the clutch members 63. The clutch members 65 are moved out of engagement with the clutch members 63 by means of split collars 67 engaging grooves in the clutch members 65 secured to vertical rods 68 mounted to slide in bearings 69 in the frame of the machine. Upon the lower ends of the rods 68 latches 70 are pivotally mounted which are normally held in line with the rods by means of the springs 71. The lower ends of the latches are arranged in the path of movement of stop pins 72 projecting from the sectors of the jack supporting arms 4. The stop pins 72 are so arranged that when the jacks are in a position of presentation the stop pins are in engagement with the lower ends of the latches 70 and hold the rods 68 raised with the clutch members 65 out of engagement with the clutch members 63. Each jack and its coperating form is, therefore, automatically disconnected from the driving shaft when the jack returns to a position of presentation, and when the machine is at rest with both jacks in a position of presentation both jacks and their coperating forms are disconnected from the driving shaft. The acks and their cooperating forms are connected to the driving shaft by means of the vertical rods 58, the upper ends of which are beveled and arranged to engage stems 79 attached to the pivoted cam followers 80 carrying cam rollers 81 engaging earns 82 on the pivot shafts of the arms 1. The earns 82 are actuated during the oscillating movements of the arms 1 by means of spring-pressed pawls 83 mounted upon the arms which are arranged to engage ratchet wheels 84 attached to the cams. The tension of the springs 77 and consequently the pressure exerted upon the sole of the shoe being operated upon is thus automatically increased during the successive pressing operations to which the sole of the shoe is subjected. The cams 82 may be held from movement during the forward movements of the arms 1 in any suitable manner. In the construction illustrated this result is accomplished by the friction between the cams and the pivot shafts.

While at rest the parts of the machine assumo the following p0sitions:-lhe arms 1 and 4 are in their extreme forward position with the jacks and forms thereon in a position of presentation. The stop pins 72, engaging the latches 70 maintain the rods 68 in raised position and the driving clutch members 63, 65, out of engagement. The stud on the shipper arm 34 is at one of the high points of the cam groove 33, so that the arm, inits extreme left hand position as viewed in Fig. 5 compresses the spring 37 which tends to throw the shipper rod to the left. The pin on the locking arm 41 is opposite a space between the projections 40 so that the locking arm does not prevent the shipper arm from moving but since the nut 21 is in its extreme left-hand position the cam projection 49 engages the detent 50, and the latter engages the collar 52 on the shipper rod and holds it in a medial position so that both pulleys revolve loosely upon the driving shaft. The low or operative portion of the cam groove 45 engages the stud on the lever 46 and the link 25 is in its lowered position, the sliding pin engaging the lower part of the slot in the lever 23.

The 0 eration of the machine is as follows e operator after placing a shoe on one of the jacks, depresses the treadle on that side of the machine. The link 57 and rod 58 connected with that treadle are raised, the incline on the rod engages the latch pin 73 and trips the latch out of engagement with the stop pin 72, and the clutch member 65 is thrown by its spring into engagement with the member carried by 1 the gear 9. These operations connect the 1 jack and its cooperating form to the driving shaft. During the de ression of the treadle the shaft 53 is rocke and the detent 50 is removed from engagement with the collar 52. The shi per rod 17 being thus released is forced to t e left by the spring 37 and one of the pulleys is movedinto engagement with a clutch member 16. The arms 1 and .4 are I oscillated backward and the jack and form press the sole by a rolling movement. As this movement of the arms is occurring the nut 21 is moved toward the right as viewed in Fig. 4 by the screw thread. By means of the connecting mechanism the be 1 ver 26 is oscillated and the lower pawl rotates the cam shaft 20 in the direction of the arrow. The stud on the ship or arm passes from a hlgh to a low place 111 t e cam groove 33, the ship or arm 34 moves toward the right, and tie spring '38 is thereby com pressed, tending to move the shipper rod 17 This tendency is opposed by the locking arm 41, the stud thereon being engaged by the outside surface of one of the I As soon as the lever 23 has 1 completed its throw and the ratchet 31 has i been advanced one tooth the locking arm is released and the shipper rod moves to the i to the right.

right under the influence of the spring 38. The direction of rotation of the driving shaft is thus reversed and the arms 1 and 4 are oscillated forward. The cam shaft 20, however, continues to turn in the same direction, and the shipper arm 34 compresses the spring 37. The stud on the locking arm engages the inside surface of a rejection 49, thereby d in its right hand pof sition until the arms 1 and 4 have completed These operations redet-ermined number of holding the shipper ro their forward movement. are repeated a times, fixed by t e number of teeth on the ratchet wheel 31.

pression on the cam groove 45 engages the stud on the lever 46, and the link 25 is lowered. This permits the nut 21 to travel farther than usual to the left, and the arms 1 and 4 are oscillated forward to the position of presentation. Just before the shipper rod is operated the nut engages the detent 5'0, and the latter arrests the shipper rod, when operated, in its medial position, both pulleys I; being disengaged, and the machine comes to crank le-' rest. Simultaneously the stop-pin 72 engages the latch 70 and disconnects the c utch members and 63 leaving all the parts in their initial position. During the oscillations of the arms 1 and 4 the pawl 83 rotates the ratchet 84 and cam 82, thereby increasing the pressure exerted by the spring 77 as the sole is reduced in thickness during the successive pressing operations.

Having thus indicated the nature and sco e of my invention, and having specifical y described a machine embodying a pre-' ferred form thereof, I claim as new and desire to secure by Letters Patent:
