To aZZ whom it may concern.-

Be it known that I, ALBERT F. PRESTON, of East Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Pulling-O ver Ma chines, of which the following is a specification.

This invention has relation to machines for pulling over the upper of a boot or shoe on a last for the purpose of stretching the upper and removing the wrinkles therefrom.

The invention contemplates the employment of pincers arranged oppositely to each other and adapted to simultaneously grip and pull over the upper on both sides, with means for causing the pincers to grip the upper at successive points farther and farther from the end of the shoe where the operation is begun. The parts are so arranged that the pincers and shoe are moved relatively to each otherin a line substantially parallel to the median line of the sole, provision being made for a certain amount of loose movement of the shoe, so that the strain is equalized on both sides ofthe shoe, whereby l'experiencenodifliculty in pulling over the edges of the upper at the shank, the two edges of which are ditferently curved. This loose movement also permits the employment of the same machine for right and left shoes, as well as for shoes of varioussizesandshapes. Asillustrated upon the drawings, the shoe is moved longitudinally relatively to the pincers, the feeding being accomplished by foot-power and the extent of feed being determined by the will of the operator.

The invention also contemplates the employment of jaws for initially gripping the toe end of the upper, said jaws acting as a gage to determine the length of the tip and insuring that the latter is squared prior to the operation of pulling over, and it further contemplates the employment of a holddown to engage the sole when the jaws are grasping the toe end of the upper.

Another feature of the invention, which I regard as desirable, is that the pincers are moved in a plane substantially parallel to the plane of the sole and not in lines perpendicular to the said plane, and consequently there is little tendency to strip the insole from the last. The pincers automatically follow the face of the sole of the last as the shoe is fed to cause them to engage successive points on the side edges of the upper, said pincers being likewise formed so that their engagement with the edge of the upper is always assured.

By means of the machine which I have illus trated as embodying the invention I am able to pull over a m uch greater number of shoes in a given time than has. been possible with machines as hitherto constructed or proposed, and at the same time I am able to accomplish much better results and to insure that the creases and the stretch are entirely taken out of the leather that constitutes the upper.

I have contemplated embodying the invention in numerous difierent forms and have illustrated upon the drawings and shall now proceed to describe the best embodiment of the invention now known to me; but I do not limit myself to the details of construction herein described, as the machine may be greatly varied and changed without departing from the spirit and scope of the invention.

Referring to the said drawings, to which I have previously referred, Figure 1 represents in plan view a pulling-over machine embodying myinvention. Fig. 2 represents the same with the grippers or pincers in the positions assumed by them at the completion of their inward movement over the sole. Fig. 3 represents a front end elevation of the machine. Fig. 4 represents a longitudinal section through the same. Fig. 5 represents a side elevation of the machine with the gripper-carrying head in operative position. Fig. 6 represents a somewhat similar View with the head in operative position. Fig. 7 represents a section through the same. Fig. 8 represents a transverse section through the machine. Fig. 9 represents another section through the machine and illustrates the grippers or pincers as just grasping the edge of the upper. Fig. 10, Sheet 2, illustrates in detail the mechanism employed for causing the feeding operation. Figs. 11 and 12 illustrate the mechanism for grasping the toe end of the last.

As illustrated upon the drawings, the machine comprises a base 20, at the sides of which, at the rear end, project uprights or standards 21 21 to receive the pincer-carrying On the base rests a carrier 23, which head.

- in the base.

is adapted to slidelongitudinally thereof between the standards 21. Said carrier is held looselyin place bya pin 24, projecting through a slot 27 in said carrier and through a slot The pin is preferably less in diameter than the slot 27, so that the carrier is adapted to move laterally relatively thereto to alimited extent. On its upper end the pin is provided with a large head 28 and on its lower end with a block 26, adapted to slide in a groove 29 in the under side of the base. On its under side the carrier 23 is provided with two rows of rack-teeth 30 31, with which engage pinions 32 32 on the ends of shafts 33 33, journaled in the base. The pinions are 7 provided with hubs through which pins are passed into slots in the shafts, the said slots being provided for the purpose of permitting a slight rotary motion to each of the pinions relatively to the shaft. This loose movement permits a loose movement of the carrier to accommodate the last to the pincers.

Rigidly secured on each of the shafts 33 is a ratchet 34, by means of which the shafts are given a step-by-step movement. The mechanism for rotating said ratchets will be subsequently described.

In the rear of the slide, midway between the standards 21, a sleeve 35 is secured in place by passing it into a threaded aperture in the said slide, said sleeve being internally threaded to receive a screw-bar 36, having a head 371, with apertures 381 to receive a tool by means of which it may be rotated. The said screw-bar serves as a support for the top of the last when the latter is turned upside down and placed in the machine. In the front end of the carrier is formed a groove 37 to receive the base of a post 38. A screw-bar 39 is passed through a threaded aperture in the base of the said post and at its end is rotatively secured in the carrier or slide 23, as shown in Fig. 4; By rotating said screw-bar the post 38 can be adjusted back and forth along the carrier. This post is curved forwardly and upwardly and is then bent downwardly and rearwardly at its upper end, being bifurcated at said end to receive a pin or stud 40. The holddown is fulcrumed on said stud, and it consists of a lever 41, having a curved end 42, adapted to engage the insole, and a handle 43. A gripper is likewise pivoted on said stud 40, and it consists of the jaw 44, adapted to coactwith the stationaryjaw 45, formed on the post 38, as shown in Fig. 4, said gripper having two arms 46 46, through which the stud 40 extends, said arms being extended or projected longitudinally for a purpose which I shall now describe. The lever 41 is provided with lateral projections 47 47, which are adapted to engage the said arms 46 when said lever is rocked in either direction. \Vhen the lever is swung to the left in Fig. 4, the projections 47 engage the forward part of the arms 46 and force the jaw 44 against the jaw 45, the faces of said jaws being eccentric of the stud 40. This grips the upper between .passed through the standards 21.

the two jaws. When said handle 43 is swung to the right, however, the projections engage the extensions of the arms 46 and move the jaw 44 into an inoperative position to release the upper. Below the holddown the post 38 is provided with laterally-projecting bosses 48, and through said post and bosses is passed a stud or pin 49, on the projecting ends of which are fulcrumed two levers 5O 50, connected at their outer end by a cross-bar 51. A roll 52 is journaled in the other end of the levers and is adapted to receive the end of the last, as shown in Fig. 4. A spring 53 is connected to the cross-bar 51 and to a stud 54 at the base of the post to hold the roll yieldingly upward toward the end of the holddown.

When the shoe is placed in the machine, itis turned upside down, as previously stated, and the top of the tee is rested on the roll. Then when the lever of the holddown is swung to the left in Fig. 4 the end of said lever engages the insole and forces the shoe down upon the roll and at the same time causes the gripper to engage the toe of the upper.

In order to limit the extent to which the end of the upper is inserted between the jaws of the gripper, I employ a gage consisting of a screw 100, which is threaded into the post and lies so as to have its end projecting up from the face of the stationary jaw far enough to be engaged by the upper. The movable jaw is slotted or grooved to escape the end of the screw. By this device the exposed length of the tip or upper upon the shoe is graduated.

The pincers are mounted upon a head which is adapted to oscillate about a horizontal axis transverse of the path of movement of the carrier. Said head consists of two side plates 55, fulcrumed on studs 56, Said plates are connected by two cross-bars 57 57, placed in recesses in the tops of said plates, and above said cross-bars is a top plate 58, held in place by screw-pins 59 6O 61 62, as shown. In addition to securing the cross-bar 57 and the top plate 58 together the screw- pins 59 and 60 secure in place a forwardly-projecting abutment 63, in the end of which is an adjusting-screw 64, rounded at its end to rest upon the insole. This abutment is located mid way between the side plates 55. The forward cross-bar 57 is projected laterally beyond the side plates 55, and the top plate 58 projects laterally to the same extent.

The pincers each consist of two jaws 66 67, having downwardly-projecting lips 68. The jaw 67 consists of a long lever pivoted upon the stud 62, which is passed through the top plate into the top of the side plate, said stud being located at the rear edge of the top plate, and whereby the lever 67 is comparatively long, and its free end is adapted to swing transversely of the sole of the last, as shown in Fig. 1. The jaw 66 is fulcrumed near the free end of the lever 67 byastud 70. This jaw is comparatively short, and its rear end is connected to the stud 61 by toggle-levers 71 72, pivoted, respectively, to the rear end of said jaw 66 and the stud 61. On the stud 73, which connects the toggle-levers at their knuckle, is a washer 74, provided with laterally-projecting ears, to which is secured a chain or other flexible connection 75. Said chain passes rearwardly around the roll 7 6, journaled on the stud 77, projecting laterally from the side plate, and then in front of the roll 78, journaled on the stud 56. Said chain is then connected to a rack-bar 79, adapted to engage the ratchet 34.

I have described the pincer mechanism at one side of the machine; but it will be understood that that at the other side is similar thereto, and I have placed upon the drawings the same reference-numerals which I have used to denote the various parts which correspond to those I have just described.

The rack-bars at their lower ends are connected by suitable connections with a treadle mechanism, (not shown,) so that by depressing the treadle and drawing upon the chain the jaws of the pincers willbe first closed and then swung inward toward the median line of the sole around the fulcrums 69,

The movement of the pincers is simultaneous, both being connected to and operated by the said treadle mechanism. To return the pincers to inoperative position, the toggle-levers 71 72 are provided with studs 81, connected by a spring 82. When the machine is not in use, the swinging head which carries the pincers is held upright by springpressed pins 84, arranged in the standards 21 and entering sockets in the side plates, as shown in Fig. 8; but when the machine is in operation the head is swung forward and rests with considerable pressure against the insole, as previously described, and for the purpose of swinging the head forward the side plates are forwardly extended at their lower ends and provided with laterally-extending handles 87.

The rack-bars 79 pass downward through apertures in the base-plate and are in engagement with the ratchets, except when held out by the mechanism which I shall describe.

Mounted loosely in horizontal slots in the standards 21 are two dogs 88, each of which projects laterally in both directions beyond the sides of the standards. Said dogs are held in place by screw-pins 89, which extend into sockets therein, and they serve as fulcrums around which the dogs may swing. To the side plates are secured two downwardly-projecting fingers 90, which when the pincer-carrying head is horizontally bearing against the inward ends of said dogs cause the outer ends of the same to force the rackbars away from the ratchets; but when said head is tilted forward said fingers are moved out of engagement with said dogs, and the downward pull or weight of the treadle on the rack-bars brings them into engagement with the ratchets. The position of the roll 78 on the stud is such that when the chain is drawn taut the teeth of the rack will engage the teeth of the ratchet The operation of the machine is as follows:

The insole is first tacked upon the sole of aagainst the gage-screw to square the end i relatively to the last. Then the holddown is forced into position, this causing the gripper to firmly engage the upper and draw the same taut longitudinally of the last. The tilting head is then swung forward until the screw 64 rests upon the insole. The carrier this time has been moved rearward to its fullest extent. As the head is swung downwardly the edges of the upper along the sides are inserted between thelips 68 68 of the pincer-jaws. Then the treadle is depressed. This causes the pincers to grip the upper at points opposite each other and to draw the edges of the upper at points opposite each other and to draw the edges of the upper transversely of the sole, toward the median line thereof. When the upper has been stretched to the greatest possible extent, tacks are inserted by any suitable tacking mechanism to prevent the upper from contracting. Then when the foot is raised from the treadle the springs 82 swing the pincers back and lift the chains, and the rack-bars are raised to rotate the ratchet and advance the carrier relatively to the pincers. As the carrier advances the edges of the upper slide through the jaws of the pincers,

but are not disengaged entirely therefrom, so that the next time the treadle mechanism is depressed the pincers engage the upper at the edges a slight distance from where they were previously engaged and draw the upper across the sole, as described. Thisoperation is continued until the shoe is fed its entire length under thehead,the upperbeinggripped at successive points and being drawn taut across the sole. It is not essential, although desirable, that the upper should be tacked in place each time it is drawn across the sole. WVhen the pincers engage the upper along the shank, the carrier moves laterally to one side or the other to equalize the strain upon the upper, this being permitted by the pin which passes loosely through the slot 27,and it will be seen that the rack-teeth 31 on the underside of the carrier are elongated to permit considerable lateral movement of the carrier. Consequently the edges of the upper are drawn over the sole practically to the same extent on either side thereof, regardless of thecurvature on the edge of the sole, this being accomplished automatically as the work progresses. After the sides of the upper have been stretched and tacked the shoe is subsequently placed in a machine for wiping over the ends of the upper at the toe and heel.

To one familiar with the art of pulling over shoes it will be apparent that the present invention which I have just described possesses ICC is placed accurately upon the last.

many features of advantage. in the first place, but two pairs of oppositely-arranged pincers are provided for drawing the upper taut over thelast instead of a number of pairs, which complicate the machine and make it hard to use. Again, the pincers are not arranged to pull first in lines perpendicular to the plane of the sole, then across the sole; but, on the contrary, their only movement is transversely of the sole, and naturally there is little tendency toward stripping, the insole from the sole of the last.

The strain on the two sides of the upper is automatically equalized without any manual effort on the part of the operator, and consequently the leather of the upper is well stretched to remove wrinkles or creases and By reason of the head resting loosely upon the insole it follows the curvature of the sole automatically, and consequently there is little tendency of the upper being disengaged from the jaws, and all that is necessary for the operator to do when using the machine is to guide the carrier as it is moved forward and to operate the treadle mechanism. It is possible for the operator to obtain a strain diagonally of the solo by twisting the carrier or swinging'the front end to one'side or the other.

It is evident that many changes may be made in the machine, as I have previously stated, without departing from the spirit and scope of the invention.
