Application filed December 22, 1909. Serial No. 534,520.

To all whom it may concern:

Be it known that I, J OSEPI-I PARTY, a citizen of the Republic of France, and resident of Paris, Seine, France, have invented new and useful Improvements in Lasting-Ma chines, which improvements are fully set forth in the following specification.

This invention relates to certain improvements in lasting machines and more particularly to machines of this character adapted for assembling the upper, sole and insole by means of a pasting operation.

The machine and method of using the same is illustrated by way of example in the drawing, in which Figure 1 shows an upper and an insole before gluing, Fig. 2 an upper and an insole when pasted upon which has been placed a sole, Fig. 3 is a side elevation of the ma chine, Fig. 4 is a front elevation. Fig. 5 is an elevation to a larger scale giving the de tails of the mold carrier which serves to effeet the pasting operation, Fig. 6 is a plan of the same device. Fig. 7 is a front elevation; Fig. 8 is a side elevation, and, Fig. 9 is a plan of the machine for assembling the upper and insole.

The inventor may make up the soled slippers and similar footwear, on the one hand by pasting the upper on the insole by means of a machine which is a modification of that of Figs. 3 and 4, and on the other hand, he may paste the sole on the slipper or the like by means of an independent apparatus also illustrated by way of example in the accompanying drawings in which- Figs. 1 and 2 indicate different phases of the manufacture through which the slipper passes. An upper a, of cloth or other material, is mounted on a wooden last 6. The edges 0 of this upper are coated inside with a layer of paste. A piece or insole (Z is then arranged on the last I), and the edges 0 of the upper a are applied upon the insole d as indicated by the line 6 in F ig. 1. These two parts being assembled, always on the last 6,

the sole f previously coated with paste is applied thereto and a heavy pressure is then exerted on the whole. A short length of time is in general suflicient for perfect pastwhole in order that the ing, the final drying operation taking place without pressure.

The method of application of the paste may vary, as well as the composition of the paste. The different parts composing the slipper to which the paste is to be applied, may be coated with paste a long time beforehand. This manner of proceeding results in an increase in the output, and it is sufficient to exert a heavy pressure on the paste may penetrate the cloth.

The machine intended for the manufacture of these slippers, which is illustrated in Figs. 3 and 4, comprises a cast iron frame 9. supporting a table 7L which carries the mold carrier 2'. The latter is formed of two principal parts j and is mounted on the table h by means of rod Z fixed by screws. The rods Z project into notches m provided in the table 72. at distances corresponding to the dimensions of the mold carrier used.

To the upper end of the rods Z are fixed other horizontal rods n on which the two members j and 7c of the mold carrier 71 slide by means of the lugs 0. The members j and each carry a half mold 79 corresponding to half a slipper, and springs q continually tend to bring them in contact. while enabling them to be separated from each other according to the width of the slipper placed inside the recess formed by the parts 2). The internal face of the half molds 79 is provided with a series of holes in which are placed rubber studs r adapted to stretch the cloth when the last covered with the upper, is introduced into the recess.

On each of the members j and 7c are arranged other parts 8 which are displaced along slides a under the action of rods 6. These parts are adapted to paste the upper to the insole by folding the margin of the former on the latter and maintaining them for an instant pressed hard against each other. The parts .9 must be able to lift slightly by coming in contact with the last placed at 7) in order to exert the pressure necessary to effect pasting. To this effect, a plate osubjected to the action of a spring :12, is combined with each of the slides u in order to oppose the requisite resistance to the lifting movement of the parts 8.

Leaf springs 3 placed at the ends of the recesses 0 allow the sole f to be placed with precision on the upper a already pasted to the insole. These springs disappear in grooves at the moment of passage of the parts 8.

The advance of the parts 8 by means of the rods 6 takes place under the action of arms a pivoted at 1 and actuated by means of cams 2 fixed to the shaft 3 which receives its movement from a pulley 4 over which passes a belt 5. A friction clutch 6 may be mounted on the shaft 3 so as to enable the latter to be set in rotation.

In order to enable the last I) to be placed completely in position in the recess 10, it is necessary to exert a heavy pressure on it which results in the separation of the members j and 72 from each other and allows the cloth of the upper a to stretch on account of the'friction with the rubber studs r. This pressure is obtained by means of a part 7 fixed to the end of a shaft 8 movable with slight friction in a tube 9. The upper end of the shaft 8 which projects beyond the tube 9 is surrounded by a helical spring 10 which maintains the part 7 in a raised position, by resting on the one hand upon the part 11, and onthe other hand upon the upper end of the tube 9. Lowering of this device is performed by acting on the pedal 12 which engages the bar 13 attached at 14 to a rod 15 pivoted at 16, which operates part 17 moving in a slide 18, and which carries a bent arm 19 whose end when lowered rests upon the part 11 in order to produce the displacement of the shaft 8.

In order to paste the sole f on the upper a provided with the insole (Z, it is necessary to exert pressure upon the whole of the sole f. With this object, a pressure block 20 having the form of the sole f is fixed to the lower end of the hollow tube 9 which carries a rack 21 capable of being lowered by means of pinion 22 fixed on the shaft 23 which is itself driven by the pulley 24 over which passes the belt 25. This descending movement of the pressure block 20 may be obtained by operating the fly wheel 26 by hand.

The tube 9 when being lowered draws with it the part 27 and the rods 28, thusproducing compression of the springs 29. A pawl 30 engaging with a ratchet wheel 31, maintains the rack 21 in the position resulting from the displacement of the pinion 22. I

v When pasting of the sole f is completed, in order to again lift the pressure block 20, it is sufiicient to press upon the rod 32 in which the pawl 30 terminates. The latter is thus disengaged from the ratchet wheel 31, and the rack 21 being no longer held,

- rises under the action of the springs 29 taking with it the pressure block 20. A recess 33 provided in the pressure block 20 receives the part 7 at the moment of pressing the sole f against the insole d.

Openings 34 are provided in the last I) for receiving a rod 35 whose object is to bring out the last I) from between the members 3' and is when the operation of pasting is completed. This rod rests upon an arm 36 pivoted at 37, which carries at its end 38 a cord or the like 39 attached to a lever 40 terminating in a pedal 41.

From what has been stated above, the

operation of the apparatus will be easily understood and is as follows: An upper a, of cloth or any other suitable material is placed upon a last 6, after having been coated at 0 with a special paste. Upon the last, and inside the edges 0 of the upper a is arranged an insole d. In certain cases, depending 011 the kind of paste used, pasting may be effected after the insole has been put in place on the last. The last I) is then introduced into the space formed by the half molds p and p ofl the members j and 70. In order to insure that the last 6 is placed in position, a pressure is exerted by the foot on the pedal 12 which engages the rod 13 and lowers the bar 15 through the medium of the part 14, by causing it to turn about its axis 16. This movement causes the part1? to move, and the part 19 fixed to the latter moves downward in the slide 18, and its curved end, by resting on the part 11 of the round rod 8, causes the latter to descend until its lower end terminating in the part 7, by pressing firmly upon the last 6, obliges the latter to penetrate into the bottom of the space formed by the half molds p and p. The result of placing the last b in position when pressing the material of the upper a firmly upon the rubber studs 1" is to produce perfect stretching of this material, at the same time as the separation of the members and 7a. The machine being in continuous motion by means of the belt 5 passing over the pulley 4 or in discontinuous motion through the medium of the friction clutch 6, the four cams 2 fixed on the shaft 3 operate the four arms 2 and cause them to pivot about the axes 1. This movement produces the normal displacement of the four parts 8 along the slides u fixed to the members j and la, namely by means of the four rods t, upon the ends of which rest the four arms a. The parts 8 on moving forward, meet the last 5 which projects slightly. The parts 8 then lift through the required amount owing to the play possessed by the plates 7) held down by the springs m. During this movement, the parts s are applied to the insole d and the edges 0 of the upper a, and keep them in this position for a very short while, which is however sufficient for insuring perfect pasting. As the movement of the cams continues, the parts 8 are drawn back and the last Z) is uncovered. The sole f covered with paste. is then taken and placed upon the last Z). The adjustment of this sole takes place automatically by means of the springs y which prevent it from projecting in any direction whatever. While the sole is being placed in position, the pressure block 20 which has the exact shape of the slipper, is lowered slowly and presses firmly against the said sole so as to paste it upon the insole d. The displacement of the pressure block 20 fixed at the end of the tube 9 is obtained by means of a pinion 22 engaging with a rack 21 fixed on the tube 9. The pinion 22 takes part in the movement of a shaft 23 upon which are fixed pulleys 24 driven by a belt 25. A ratchet wheel 31 and a pawl 30 maintain the pressure block 20 in the position given to it by the pinion 22 and it is sufficient to lower the lever 32, upon the end of which the pawl 30 is mounted, in order that the pressure block 20 may again take up its former posit-ion under the action of the springs 29 which have been compressed during its descent. Lowering of the pressure block may also be obtained by operating by hand the fly wheel 26 fixed on the shaft 23. The pressure exerted by the pressure block 20 need only last for a very short time owing to the nature of the paste used, final drying being completed when the slipper is withdrawn from the machine. The latter operation takes place in the following manner: Pressure is exerted on the pedal 41, to the arm of which is attached a cord 39, con nected at 38 to a lever 36, upon the end of which rests the rod 35. This rod which slides in the table it, penetrates one of the openings 34 provided in the last 6, and by lifting it disengages the same from between the members j and 70; It will therefore be sufficient to seize the last Z) and to remove from it the upper a provided with the insole (Z and the sole f. In case the paste is spread on the different parts a certain time before the pasting operation, it becomes necessary to raise it to a temperature which allows perfect pasting to be efiected. For this purpose a gas heating apparatus or any other source of heat may be arranged under the different parts composing the mold carrier 1', which, by heating the parts, brings about a resoftening of the paste.

In order to accelerate the output which is somewhat retarded in the machine above described by the duration of the operation of pasting the sole under the slipper, which is greater than that of the operation of assembling the insole and the upper, it is convenient to carry out this assembling in a machine constructed solely for this purpose, the

operation of pasting the sole under the slipper being carried out in an independent device which may be multiplied on account of the production of the preceding machine.

The machine intended to make up the slippers, that is, to assemble the upper and the insole only, comprises a plate 42 mounted on a frame 43 which at the same time carries the bearings 44, 44. (See Figs. 7, 8 and 9.) On the plate or table 42 are placed supports 45 adapted to receive the parts 46, 46 whose inner sides are formed with two steps, the first supporting a part in two pieces 47 receiving the last on which is mounted the upper, and the second supporting parts 48, ,48 applying the edges coated with glue of the upper, upon the insole.

The part 47 is formed in two pieces held against each other by means of springs 49, 49. These parts may open so as to allow the last to enter and leave under the action of a pedal 50 fixed to a drum 51 on which are rolled cords 52, 52 fixed respectively at their other ends to the portions of the part 47.

The parts 48, 48 are held by means of leaf springs 53 fixed to the supports 46 46. The displacement of these parts for the application of the edges of the upper upon the insole, is obtained by means of the arms 54, 54, pivoted at 55, 55 and terminating at their lower ends in rollers 56, 56 which are displaced inside rolling guides in the form of cams, of the part 57 The arms 59 which connect the parts 48, 48, are arranged so as to be able to be extended to suit the taper of the slippers to be made up. The parts 48, 48 may be provided with extensions 58 for this purpose. The taper of the slippers necessitates also the transformation of the inner last-receiving portion of the two parts 47 For this purpose parts 60, 60 conforming exactly to the internal shape of the two parts 47 are arranged within the latter where they are held by tenons 61. The inner face of the parts 60, 60 has thus a less taper than the parts 47 and any required number of those parts may be employed for obtaining different tapers. But as such parts may become too thick, it will be preferable to change the parts 47 for other parts suited to the different taper of the slippers to be made up.

The arrangement of the parts 48, 48 has merely the purpose of pasting the sides of the upper upon the insole, so that it is still necessary to apply the toe and heel portions of the upper upon the insole. For this purpose parts 62, 62 are jointed to the ends of arms 63', 63 and held by springs 64, 64 against the parts 47. The arms 63, 63 are connected at 65, 65 to the vertical arms 66, 66 that are pivoted at 67, 67 and that terminate at their lower ends in rollers 68, 68. These rollers are in contact with cams 69, 69 mounted on the shaft 70 on which the double cam 57 is also fixed. Springs 71, 71 keep the rollers 68, 68 on the rolling surfaces of the cams 69, 69.

The arms 63, 63 are supported in brasses 72, 72 which move in guides provided in the bearings 44, 44 by means of screws 73, 73 operated by means of the hand wheels 74, 74.

The length of the arms 63, 63 is adjustable in the manner previously indicated for the arms 59, that is, the part 75 penetrates the hollow portion 76 of the piece 63 and is fixed by means of the collar 77. Since the arms 63, 63 during their forward or rearward movement remain horizontal, their connection with the arms 66, 66 takes place by means of the rollers 78, 78 which move in the openings 79, 7 9.

'In order to deaden shocks, and at the same time to hold the last in position, the latter rests upon the end of a rod 80 passing through a bearing 81. A spring 82 allows the rod 80 to be lowered and lifted according to the working of the machine.

The general movement is obtained by means of a fly wheel 83 mounted on the shaft 70 and actuated by the workmans hand. From the foregoing, the manufacture of a slipper will be easily understood.

After having placed an upper on a last, the upper is coated with paste on the internal edge, and the inside is then placed on the last. The last is now introduced between the two portions of the part 47, or if necessary between the parts 60, 60' and the fly wheel 83 is then actuated by hand. The introduction of the last is facilitated by opening the two portions of the part 47 by means of the pedal 50 acting upon the cords 52, 52. The handwheel 83 operates the shaft 70 on which are mounted the double cam 57 and the two cams 69, 69. The cams 69, 69 cause the parts 62, 62' to advance and press the upper firmly against the insole. The same movement is made by the parts 48, 48' which are caused by the double cam 57 to move against the sides of the last and apply the pasted edge of the upper upon the insole. The return movement of the part 62 takes place in one operation, but the return movement of the part 62 takes place in two operations in order to enable this part to bear more firmly upon the folds formed by the upper at the heel, this being effected by means ofthe cam 69 which has two humps that cause the said part to dwell for a more protracted period during the movement of the parts 48, 48. When the upper has been pasted on the insole, the two portions of the part 47 are moved apart by means of the trcadle 50, and the made-up slipper is removed from the apparatus. After the upper and insole have been assembled in the manner above described the sole may be applied by any suitable form of machine or apparatus, such sole applying machine forming no part of the present invention.

It is to be understood that the machine in its modified forms may be employed for making up slippers and the like by stitching or by sewing with string.
