Serial No. 624,983.

To all whom it may concern Be it known that'I, ORRELL Asn'roiv, a citizen of the United States, residing at Swampscctt, in the county of Essex and State of Massachusetts, have invented certain Improvements in Stock Manipulating and Tacking Apparatusfor Use in the Manufacture of Boots and Shoesyof which the following description; in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invent-ion relates to machines for use in the manufacture of boots and shoes.

A general object of this. invention is to improve shoestock manipulating and fastening apparatus.

A more particular object for which the illustrated. embodiment of the invention has been designed is to provide an improved fastening apparatus for use in connection with a machine for preparing the shoe for the operation of such a pulling over and toe lasting machine as that shown in United States Letters Patent No. 1,137,564, granted on my application April 27, 1915, and for doing any further lasting and tacking that may be desired to complete the preparation of the work for the shoe sewing operation in which the upper and sole, or inner sole and welt, are permanently secured together.

With these objects in view the machine with reference to which the invention will be explained comprises a gripper and a tucker which can be used with the gripper for lasting operations and can also be used Without the gripper for shoe assembling and other operations. i p

This invention is shown as embodied in a machine of the type shown and described in United States Letters Patent No. 1,050,904,

granted on my, application January 21,

1913, of which this application is a division. In machines of thetype just referred to the gripper is arranged to extend transversely across the shoe bottom to engage the upper on the side of the shoe more remote from the machine frame and opcrating mechanism is provided to move the gripper inwardly for pulling the upper toward the machine.

A. feature of this invention consists in the organization of a lasting machine which permits or causes the gripper after seizing the upper to transfer the shoe into tack receiving relation to the tacker and then to pull the upper andhold it under tension while the tack is driven. This feature has the advantage that a stationary tacker may be employed and the machine simplified be cause no tacker moving mechanism is required.

A. further feature of the invention consists in the organization of alasting machine having a gripper arranged and oper ating as above described with a shoe rest which may advantageously be arranged to engage in the outwardly and downwardly inclined channel incision of the sole, mounted to project normally into a shoe receiving position in which a shoe may conveniently be applied thereto, and then to be moved into its shoe resting position. This mounting facilitates the presentation of the shoe to the rest and enables the rest to guide the shoe into operative relation to other instrumentalities of the machine. Preferably the rest will be mounted so that by adjustment or otherwise it may be made to project with relation to the lower or inner gripper jaw and sothat it can yield to pressure for guiding the uppermaterials into the jaws of the gripper. After the jaws close, as herein shown, they move inwardly and carry the upper and, through the shoe, the rest backwardly until the movement of the rest is interrupted by an abutment between which and the rest there is relative adjustment to determine the position of the shoe relatively to the tacker. After the grippers, having transferred the shoe to tacking position, have continued their movement to pull the upper a tack is driven while the grippers continue to hold the upper. ihereafter,in accordance with a further feature of this invention the sole rest'is actuated to move the shoe outwardly in unison'with the outward or return movement of the jaws. Preferably the rest is so moved unyieldingly forked to permit the nozzle of the tacker to project into desired relation to the plane of the shoe bottom and preferably the sole rest or the gripper or both, form spacing means to hold the shoe away from the nozzle and from the lowerlimit of the driver path to insure a predetermined partial insertion of the lasting tacks which are later to be pulled out.

'Preferably the gripper is removably mounted in its working position so that it can be shifted relatively to the tacker into a position to permit the use of the tacker alone. hen the tacker is to be used without the gripper and sole rest for inserting upper holding tacks which must later be pulled out other means is employed in accordance with a further feature of this invention for serving the work-spacing func tion which the gripper or the sole rest, or both, serve when in their operative positions. The tacks which it is contemplated .will be inserted while the gripper is idle include those located at the ends of the heel stiffener and those shoe assembling tacks which are located in the heel seat face and the end face of the shoe at the rear of the heel. The tack thatis driven intothe rear end face of the heel should be left outstanding only a little while the other tacks mentioned may be left upstanding to a greater extent and thereby rendered easier to pull. In view of theseconditions means is provided in accordance with this invention for spacing the shoe at different distances from the tacker to cause the tacks to be left upstanding different distances. This means herein includes spacing plates movable into cooperating and preferably. interlocking relation to the tacker, one of which may be movably mounted upon the other. There is also provided a stock bending de-, vice to cooperate with the thicker spacing plate in heel seat tacking. This device 1s formed to bend the heel stiffener and upper materials at an oblique an le over the edge of the shoe bottom and hold them while the temporary tack is driven to hold the stock ready for the permanent fastening.

These and other features of this invention will more fully appear in connection with the following description of a preferred embodiment of the invention and will then be pointed out in the claims.

Fig. 5 showing the thicker spacing block and the stock bending device in working position. F 6 is a perspective view of the gripper and sole rest.

' The frame 1 of the machine provides sup port for the upper pulling devices and for the tacking devices and'has bearings for a shaft 5. The shaft is connected with a continuously running pulley 8 by a one revolution clutch of known construction, which is controlled by a rod 6 and a treadle not shown. The shaft carries a gripper operating cam 10, a driver lifting cam 12 and a sole rest controlling cam 14:.

The grippercarrier 20 is an angle plate having a vertical edge wall and a bottom wall and is supported at its rear end by a pin and slot pivotal connection 21 with an arm 22 which is pivoted at 28 to the frame. The front end of the gripper carrier is supported, with the gripper in operative position, by a bolt 25 which can be withdrawn toward the right in Fig. 3 to allow the grip per mechanism to swing down into the inoperative position shown in dotted lines in Fig. 1 at such times as it may be desired to employ only the tacking devices of the machine. I

The bolt 25 has on its left hand end a stud, Fig. 3, which engages an annular cam face 29, Fig. 2, on the gripper carrier to clamp the carrier firmly against the machine frame when the bolt is turned in one direction by its handle 26. The bolt is encircled at its right hand end by a stiff spring 31 which is under compression between the handle 26 and a collar 27 which abuts against a portion of the frame 1, Fig. 3. This spring tends to force the stud on the left hand end of the bolt into its seat 39 in the cam face on the gripper carrier and to clamp the carrier firmly against the frame. When the bolt 25 is reversely turned from its position the stud is dislodged from its seat in the cam face of the gripper carrier and is brought into alinement with a recess 33, Fig. 2. that is cut through the carrier and into the frame and which permits withdrawal of the bolt. This allows the gripper mechanism and the sole rest to swing about the pin at 21 intov dotted line position. Fig. 1, and leaves the tacker nozzle exposed as in Fi s. 4 and 5. A second spring 41.

ranged between the frame and the end of a sleeve 4-3 which slides in the frame andabuts against a shoulder on the bolt. The collar 27 is conveniently formed on this sleeve.

The gripper comprises an upper jaw and a lower jaw, the gripping face of which latter is formed by the beveled end'of a hori zontally arranged bar 30. This baris movable endwise in the gripper carrier and has ears at its rear end through which extends the pivot bolt 21. The bar andtherefore the lower jaw is pressedforwardly by a spring 32, Fig: .3, which extends under tension for closing the jaws from a clip secured to the rear end of the bar to a clip attached to the upper jaw. This forward movement of the lower jaw by the spring 32 is limited by slots in the rear and front portions of the gripper carrier, Fig. 1, through which the bolt 21 and a headed guide screw 12.1;extend respectively. This movement may be further limited by the adjusting screw 36,' Fig. 1, which is arranged in the frame to engage a forwardly projecting arm of a bell-crank, the other arm 22 of which carries the bolt 21. The upper jaw of the grippers is formed on or removably attached to an endwise sliding bar 40 which has a tongue and groove sliding connection with the top face of the lower jaw bar 30. This bar has on its upper side a boss provided with a seat 44., Fig. 2, for the head of its operating bar by which the upper jaw is moved first to grip the stock against the lower jaw and then, by force transmitted from the upper jaw through the stock, the lower jaw is moved backwardly with the upper jaw to pull the upper relatively to the last which is held by the back rest 60 as'shown in Fig.2. This motion istransmitted to the operating bar from the cam 10 by a lever 46 which is fulcrumed on a stud 48 which is rigidly fixed in theframe and has a roll standing against the edge of the cam block. The fulcrum stud 48 for this lever is encircled loosely by a strong coiled spring 49, one end of which is fastened to the stud and the other end of which acts'torsionallyagainst the lever 46 in thedirection to close the gripper jaws. The operating bar 45 is guided under an idler roll 50 and it is held up against that roll when the gripper mechanism is turneddown into the dotted line position, Fig ljby 'a'sp'ring 51 which encircles the bolt 53 and underlies the bar L5 as in full lines, Fig. 1. l

A spring plate 54: attached to'the gripper carrier 20 is provided with a tooth 55 which engages a notch in the side of the upper jaw v bar 40, to lock that bar against backward movement by the spring 32 when the bolt 25 is withdrawn. This spring plate is pressed away from bar 40 by the bolt 25 to permit operative movements of'the jaw while the gripper is in useandthe plate automatically reengages the bar when the bolt is retracted. 1 his latch plate not only prevents the jaws from closing while the gripper hangs down, Fig. 1, but it maintains the operating bar seat 4% in bar 40 in longitudinal position for reengaging the operating bar when the gripper is returned toworking position.

The rest which is arranged to engage the sole of the shoe to resist the backward pull of the gripper is adjustably mounted by a split holder 61 and a clamping screw, on a rod which slides endwise in bearings 62 on the lower side of the gripper carrier 20 and the rest is normally pressed forwardly by a spring 65 acting against one of said bearings and against a stop pin 63. The rest has a downwardly inclined bladeshaped end to enter readilythe oblique in-y cision or channel of a turn shoe sole or the corresponding formation of a welt shoeinnersole. The end portion of the rest 60 be tween the rod and the blade is bowed upwardly as at 64, Fig. 2, to give clearance for the sole and opportunity to tip the shoe as may be required in presenting difierent portions of it to the operation of the machine.

The sole rest normally projects forwardly into a position relative to the grippers which enables the operator readily to present the shoe properly thereto and to feed the shoe from one working point to the next. The rest may be then pressed backwardly by the shoe'in the act of sliding the upper into the jaws of the gripper. This rest serves as a guide for the upper in this insertion into position to be gripped and it also presses downwardly and outwardly the marginal portion 'of the sole and holds it in place to have the upper pulled over and tacked to it. The sole rest has a range of free backward movement against its spring 65 that is measured by the distance between its bearing 62 and the rear face of the holder 61, Figs. 1 and 2. As the grippers pull backwardly they move the shoe, together with the sole rest, until the holder abuts against the bearing as in Fig. 2. This movement of the shoe carries it under the stationary tacker noZZleSO and into position to receive the fastening tack while the upper is being initially pulled or straightened over the last and before the'final upper tightening pull is effected. Thereafter the rest becomes fixed and the grippers pull the upper to stretch it over the last with a force determined by the tension of the 4:9 and the holding spring 32.

The sole rest not only constitutes the work guide along which the shoe may be moved in feeding for side lasting but also it adjustably regulates thedistance from the edge of the shoe at which the tacks shall be driven. This is important for in making turn shoes the tacks should always be driven into the bepulling spring tween substance which is located between the shoulder and the lip of the sole. In this position they obtain the greatest holding engagement with the sole without going through the sole and making astain on the face side of the sole after the shoe is turned, and also they are out of the way of the channel guide of the sewing machine which would be interrupted by them if the tacks 1 were driven into the lip. It should be ob served that in accordance with this embodiment of the invention the machine, acting through the gripper and the sole rest, automatically moves the shoe into a predetermined lateral relation to the tacker for the insertion of each tack.

It is desirable that the sole rest follow the grippers in their reverse movement after the tack has beendriven in order to insure that the shoe moves outwardly ahead of the lower gripper jaw which might otherwise tend to tear out the tack just driven. The sliding sole rest abutment is therefore provided, Fig. 1, which is guided in bearings in the frame and is connected with the cam 14 by a link 72 and by a lever or rockshaft which has offset arms 74', 75. The track in the cam is cut relatively to the gripper cam to give the abutment a forward stroke with the gripper return movement and then to retract the abutment as in Fig. 1 before the machine comes to rest.

The jaws 30 and 40 are preferably slotted to receive the nozzle which, with this arrangement, may be vertically stationary. The tack driving mechanism of which the nozzle is a part is supported upon the forwardly projecting portion of the frame and comprises a casing 82 in which is movable the driver bar 8& which is provided at its upper end with a head 85 that is arranged to be engaged by the outer end of thelever 86 fast on the rod or axle 87. A coiled spring 88 encircling said axlehas one end hooked over a portion of the frame and the other end fastened to a flange 90 of a sleevethat is held by a binding screw 91 in angularly adj usted position on the axle with the spring 88 under tension to actuate the driver lever downwardly. A roll 92 on the lever rests upon the driver lifting cam 12 which is in appropriate form to let the driver lever and bar descend abruptly to insert a tack by impact. The driver lever is flexibly connected to the driver bar for lifting thelatter by a resilient device shown best in Fig. 3 and comprising the cross bar 93, the upturned spring eyes 94iand the depending arms 95 having inturned lower ends which hook into recesses in the driver head 85 to raise the latter. Tacks are supplied as herein shown froma tack strip which is automatically advanced in time relation to the movements ofthe driver y al m u f xample, as

ent No. 483,375. The shoe rest and p the grippers are so positioned relatively to the nozzle that the tacks which are driven to fasten the upper temporarily in lasted position are leftupstanding or only partially driven to facilitate pulling them out after the shoe is'sewed.

In the use of the machine built as ab ve described, to embody the present invention, a shoe is supported bottom upwardly, preferably in the; hands of the operator, the sole is pressed against the rest 60 which may enter the channel or engage the lip of the sole or innersole and the upper on that side of the last which is toward the operator is inserted between the open jaws. With the work thus presented, the shoe will be forced backwardly against the yielding sole rest, or to ward the machine, more or lessaccording to the. length of grip it is desired to obtain on the upper. The starting treadle is then depressed to pull down the clutch rod 6 and start the machine. The jaw bar 40 is first moved in its horizontal path to grip the upper against the jaw30 which then begins to slide backwardly whereby the upper is pulled with a force determined by the ten-. sion of the spring 65 against which the sole rest yields backwardly to allow the shoe to follow the gripper. This initial upper pulling andshoe transferring movement shifts the upper and the last into tack receiving position under the tacker nozzle, Fi g. 2. After this position of the shoe is reached the further movement of the grippers back-- wardly gives the final upper tightening effect and then the driver cam releases the driver to insert a tack as shown in Fig. 2. Immediately thereafter the return movement of the gripper jaws is commenced and with it begins thev advance'of the sole rest actuating plunger 70 by which is insured the movement of the shoe outwardly in time relation with the return of the lower jaw 30 to shoe reiceiving position.v

It is sometimes desirable toinsert tacks without crowding back the sole rest and for this purpose anoblong slot 71, Fig. 6, is formed in the rest under the nozzle. This slot allows a-tack to be driven through the rest in different adjusted positions of the rest withinits holder. 'This slot also pre vents liability of. injury to the rest by the tack or driver if the machine is run idly through its cycle.

The machine may be used without the grippers with the nozzle 80 bare for heelseat tacking and other surface nailing operations such as tacking the sole to the last bottom but when inserting such assembling deyigesnraprpvided. o; sraca ha hae way- 1 so i from the nozzle as the gripper and sole rest do when they are in operative position. A post 98 at the right hand side of the machine head, Fig. 3, yieldingly upheld by a spring 99 supports an angular plate 100 which is capable of turning from the inoperative position shown in Fig. 8, where it is out of the way of the grippeninto a position in which its free end is located under the tacker as shown in Figs. 4 and 5 where it will limit the approach of the work to the nozzle and to the lower limit of the drive stroke thereby insuring partial insertion only of the tacks. A stop 102 onthe side of the gage 100 contacts with the nozzle and with the under face of the tacker head and limits movement of the gage. The gage has an opening which allows it to fit up over the nozzle far enough to lock the gage in position and the yielding post 98 and, it may be, the resilience of the plate itself causes the gage to snap up and lock automatically upon the nozzle. To obtain greater exposure of the driven tack a spacing block 110 is mounted to slide along the lower face of the front arm of the gage plate. This block is normally held back wardly as in Fig. 4 by a spring 112 and has a spring latch 115 adapted to snap into a notch 116 in the plate when the block is pulled forwardly into Fig. 5 position. This latter position is particularlv intended for inserting an assembling tack through the upper and heel stiffener into the sole at the rear end of the heel seat. This tack holds these parts of the shoe relatively to each other and to the last for the pulling-over operation and to facilitate bending down the heel stiffener into position to receive this heel seat assembling tack a bender 120 is adiustably attached to the block 110 by a bolt 122 and is provided with a beveled stock bending face 124. This bender also serves as a back gage to insure positioning of the heel seat tack outside the channel, for shoes that are sewed all the way around as is sometimes done. so that the tack will not constitute on obstruction for the channel guide of the sewing machine.

In the contemplated use of the machine the sole will first be tacked to the last bottom by the use of the tacking mechanism with the nozzle hare because it is desirable to drive the sole fastening tacks fully into the work. Then when the upper materials, have been applied to the last and adjusted the plate 100, will be swung around to operative position as in Fig. 4 where it snaps under the nozzleand the hack seam tack will be driven. Then the thicker spacing blrck 110 is advanced and with it the bending device 120. as in Fig.3. these partsbeing held in forward position by the latch 115. The shoe is then presented against. these de ices for the insertion of the heel seat assembling tack. It is the usual practice to perform each operation, as, for example, the sole tacking operation, the assembling operation, etc., upon several shoes as a dozen or a case in succession and then to proceed with the succeeding operation upon the same lrt of shres. This course may advantageously be followed in the use of the present invention and the soles tacked on the lasts for a lot of the shoes and then the machine adjusted to perform the assembling operation on the same shoes. The shoe is now readyfor the pulling-over and toe lasting machine. After it is returned from that machine the spacing devices'of Figs. 4 and 5 are returned to inoperative position, Fig. 3, and the gripper and sole rest are turned up from the dotted line position, Fig. 1, to the full line position and the'bolt 25 pressed through the'eye in r the gripper carrier 20 and turned to clamp the carrier against the machine frame. As the gripper is raised the seat 44 in the top of the bar 40 is fitted over the depending arm of the bar operating member 45 and when the bolt 25 is inserted through the carrier it presses the latch. 54, out of holding engagement with bar 40, so' that that bar is free to be moved by the operating member 45. The shoe is now presented to the machine for side lasting, as in Fig. 1, the sole being pressed against the rest so that the thin end will enter the channel incision or abut against the channel lip if the lip is upturned. The shoe is then pressed inwardly toward the frame or body of the machine until the upper is guided into the jaws or into such relation, to the lower jaw 30, that it will be gripped thereagainst when the upper jaw moves inwardly. The machineis then started by the usual foot treadle or otherwise and after the jaw 40 has gripped the stock against jaw 30 it moves the jaw 30 with it inwardly. During a portion of this movement the sole rest also yields inwardly until the enlarged holder 61 strikes the bearing 62, Fig. 2, whereupon the rest becomes a fixed abutment for the shoe and a stop relativel y to which the gripper in its continued movement pulls the upper. At the end of the inward stroke of the gripper the tack driver is released and the tack driven as in Fig. 2, being left upstanding to an extent determined by the distance from the lower end of the driver path to the sole rest. or to the lower face of the jaw 30 if the rest were not present. In the movement of the shoe and the. rest together by force transmitted from the grippers through the upper. the shre is p sitioned relativelv to the tac er and by adjusting the rest 60 in its holder 61 the relation of the tacking line to the channel and the edge of the sole can be varied.

fter the tack is driven the sole rest is p sitively moved outwardly by its actuating means in company with the grippenmovethere is no liability of the tack being dis- Having explained the nature of this in vention and fully described a machine embodying the same in the bestform now known to me, I claim as new and desire to secure by Letters Patent of the United States:
