40 Claims.

This invention relates to machines for use in the manufacture of shoes and is herein illustrated as embodied in a machine for use in assembling the upper of a tennis shoe or sneaker on its last and for securing the upper to an insole on the last preparatory to the lasting of the upper by means of a machine such, for example, as that disclosed in United States Letters Patent No. 1,843,232, granted February 2, 1932, upon application of the present inventor.

In the manufacture of tennis shoes it has been the practice for the lasting machine operator, after having mounted a last, having an upper loosely assembled thereon, upon the spindle of the lasting machine and before starting the machine, to pull the upper forwardly by his fingers so as to draw it closely about the heel portion of the last, and also to pull the opposite side portions of the upper upwardly by his fingers, to draw the upper closely about the forepart of the last, and finally to place an insole in proper position upon the last bottom.

One object of the present invention is to provide a machine which is well adapted for performing such preparatory operations as those above referred to so that the operator of the lasting machine will be relieved of the necessity of performing them manually before starting the lasting machine and which can be relied upon to operate rapidly and effectively and to insure accuracy and substantial uniformity of adjustment of the uppers on the lasts.

With this and other objects in view, one feature of the invention consists in the provision, in an assembling machine, of means for drawing an upper tightly about the heel end of a last by a pull applied at the forepart, and means for drawing the upper tightly across the forepart of the last and for securing its margin adhesively to an insole on the last at the sides of the forepart only while leaving the upper around the end of the toe unsecured. In the machine herein illustrated a last having an insole and an upper loosely mounted thereon is supported bottom downward by means of a work support which comprises a toe rest and a heel rest arranged to engage the toe and heel portions, respectively, of the insole. As shown, a toe gage and two side gages are associated with the toe rest for positioning the insole with the edge of its forepart alined with the corresponding edge of the last bottom and for positioning the last with the upper and the insole in position to be operated upon, the gages being arranged to extend between the upper and the last and to engage the edge of the insole and the edge of the last bottom, and the toe gage serving also to hold the last against forward displacement during the action of the operating parts of the machine. These operating parts, as herein shown, comprise a foredraw member, .two side wipers,'and two overlaying devices all of which are normally retracted from work-engaging positions to facilitate introduction and removal of the work. In the illustrated machine treadle-operated mechanism is provided for moving the foredraw member into engagement with the upper at a point above the toe of the last and for yieldingly pressing it toward the last to cooperate with the toe rest in clamping the last, and power means rendered operative by movement of the abovementioned treadle thereafter moves the foredraw member in a direction to draw the upper forwardly and thereby to tighten it about the heel of the last while at the same time continuing to exert clamping pressure upon the last. As illustrated, the side wipers are brought into yielding frictional engagement with the upper at the opposite sides of the toe of the last and moved downwardly to tighten the upper widthwise of the last, these wipers being brought to rest near the bottom edge of the last where they function to hold the upper in its tightened condition while the cemented margins of the upper are pressed against and caused to adhere to the bottom face of the insole by the action of the overlaying devices. As shown, the overlaying devices comprise rolls which are moved inwardly to lay the cemented margins of the upper over the insole and are arranged to exert yielding pressure to secure the margins adhesively to the insole so that the upper will be held in its adjusted and tightened condition while the work is being transferred to the lasting machine.

The invention further consists in features of construction and combinations and arrangements of parts hereinafter described and claimed the advantages of which will be apparent tothose skilled in the art.

The invention will be explained with reference to the accompanying drawings in which Fig. 1 is a view in right-hand end elevation of an assembling machine embodying the features of the present invention, the assembling machine being shown as attached to the rear of a lasting machine such as that disclosed in the above-mentioned Letters Patent No. 1,843,232;

Figs. 6 and 7 are fragmentary views partially in rear elevation and partially in section of the parts shown in Fig. 3, but showing those parts in difierent operative-positions; and

Fig. 8 is a perspective view showing an upper and an insole assembled'on a last and illustrating particularly the appearance of the upper after it has been operated upon by the assembling machine.

In the drawings, the invention is illustrated as embodied in an assembling machine which is particularly designed for attachment to a lasting machine of a type especially adapted for use in the lasting of tennis shoes or the like in which the uppers are fastened to the insoles by cement, such a lasting machine being shown at H] in Fig. 1 and being of the same general character as that disclosed and claimed in Letters Patent No. 1,843,232, hereinbefore referred to. Reference may be had to said Letters Patent if desired for a description of the construction and mode of operation of the lasting machine, although for the purpose of an understanding of the present invention it will be necessary only to know that a conveyor belt I2 is provided for carrying shoes away from the vicinity of the lasting machine after they have been operated upon and that the conveyor belt is operated through worm gearing 14 from a shaft l 6 which is driven through sprocket wheels and a chain l8 by a shaft 26 having on one end a'beveled pinion 22 operated by a bevel gear 24 secured to one side of a gear wheel 26 which is continuously running while the lasting machine is in operation.

The illustrated assembling machine comprises a casing 30 on the outside of which theoperating instrumentalities of the machine are mounted, the casing 30 being rigidly secured by means of screws 32 and a tie bolt 34 to the rear of the lasting machine Ill. Located above the casing '30 and supported thereby is a heel rest 36 and a toe rest '38 (Fig. 2) for the heel and toe portions, respectively, of a last, such as the last A, having an upper B and an insole C arranged in loose relation thereon. In Fig. 2, for convenience of illustration, the casing 38 is shown in such a position that the supporting surfaces of the heel rest 36 and the toe rest 38 are horizontal butactually the casing 30 is so positioned relatively to the lasting machine It), as shown clearly in Fig. 1, that the heel and toe rests are inclined lengthwise of the shoe so that the toe end of the shoe points upwardly and thus the operator of the assembling machine, without having to bend forwardly or assume an unnatural position, may look downwardly upon the loosely assembled upper so as conveniently to observethe conditionof -'the upper as it is being operated upon by the instrumentalities of the machine. Associated with the toe rest 38 are side gages 40 and a toe gage and abutment 42 which relatively locate the foreparts of the insole and the last and which locate and hold the last, with the loosely assembled upper and insole thereon, in position to be operated upon. The operating instrumentalities of the assembling machine are arranged higher than the casing 30 at the rear thereof and comprise a foredraw member 46 for frictionally engaging the top of the forepart of the upper and drawing the latter forwardly to tighten it about the heel portion of the :last, two side wipers 48 for wiping the forepart of the upper downwardly over the opposite sides of thelast, and two overlaying devices 50 for pressing thelower cemented margins of the upper upon the insole for the purpose of securing them thereto.

The foredraw member 46 is adapted to be moved into frictional engagement with the upper on the 'last by depression of a foot treadle 52 (Fig. 1). Continued downward movement of the treadle '52 initiates the operation of the foredraw member 46, the side wipers-48 and-the overlaying devices 56 under power, the power being vtransmitted by sprocket wheels and a chain 54 from the driven shaft 16 to a cam shaft 56 which-is journaled in bearings in the side-of the casing 36 and which carries a plurality of cams "and also'a clutch 58 of suitable well-known form, the latter being connected with the treadle 52 by means of a treadle rod 60 and being operable to cause the cam shaft 56 to make a singlerevolution and thenautomatically come to rest.

The heel rest 36 comprises a flat plate arranged to engage the insole beneath the heel end of the last. As best shown in Fig. 2, the heel rest plate 36 is provided with a cylindrical stem 62 which extends through and is arranged for lengthwise sliding adjustment in vertical bearings 64 one of which is formed in a plate 66 which constitutes a cover for the casing SO-and the-other of which is formed in a bracket 68 which is rigidly secured to the upper side of the cover .plate 66. The heel rest stem 62 is externally threaded to receive aknurled nut 10 which is located between a portion of the bracket-68 and the cover-plate 66 and is adapted to be turned to raise or lower the heel rest to accommodate lasts the bottoms of which have diflc'erent degrees of slope in their shank portions. To prevent the stem 62 from turning in its bearings and thereby enabling it to be adjusted vertically by the turning of the nut 10, akey 12 in the bracket 68 is received within a vertically elongated keyway M in .thestem 62.

The illustrated toe rest 38 comprises a fiat plate which is adjustably mounted upon a stationary bracket which projects from the side of the casing 30, the toe rest plate 38 being arranged to support the last by engagement with the bottom face of the insole at the extreme forward or toe portion of the latter. The toe rest 38 is ofsmall area, as shown in Fig. 4,and is arranged with :its lateral edges spaced inwardly substantial distances from the edges of the insole and the last bottom so as not to interfere with the movements of the overlayingdevioes 50 in pressing the margins of the upper against the insole. .As shown, the toe rest 38 has formed at its forward extremity an integral upstanding lug 42 arranged'to engage the toe end of the insole and to project upwardly beyond the insole so:as to engage also the toe end' of the last. The lug 42 thus constitutes a fixed abutment for holding the last against the forward thrust of the foredraw member 46 so as aosazaspositively to prevent any forward lengthwise displacement of the last resulting from the action of the foredraw member. The lug 42 functions also as a gage to locate the last, with the upper thereon, in the desired lengthwise relation to the operating instrumentalities of the machine and to aline the edge of the insole with the edge of the last bottom at the tip of the toe. In order that the toe gage and abutment 42 may be adjusted to accommodate lasts of different sizes and styles, a rib 82 (Figs. 3 and 5) formed on the lower side of the toe rest plate 38 is dovetailed for sliding adjustment in directions toward and from the heel rest 36 in a slideway 8 3 formed in the upper portion of the bracket 80 and a hand screw 86 is provided for effecting such adjustment. As shown, the hand screw 35 extends into a bore in the rib 82 on the toe rest 38, the threads on the screw engaging screw threads formed within the bore while at its opposite end, the screw 86 extends through and is arranged to turn freely within a. bearing lug 88 on the bracket 80. The screw 86 is held against longitudinal movement in its bearing in the lug 88 by means of a collar 89 on the screw, arranged to engage one end of the bearing lug 88, and a knurled head 90 which is arranged to engagethe opposite end of the bearing lug and by means of which the screw 86 may conveniently be turned for the purpose of adjusting the toe rest 38 and the toe gage and abutment 42.

The side gages 40 function to aline the lateral edges of the insole with the corresponding edges of the last bottom at the forepart of the last and, in addition, to locate the last, with the upper and insole loosely assembled thereon, in a central position relatively to the side wipers 48 and the overlaying devices 50. As a result of this arrangement the side wipers will so act upon the opposite sides of the upper in conforming the upper to the curve of the last as to insure against any tendency of the upper to slip sidewise in such a manner as to displace the throat opening in the upper from the desired central position on the last or to cause the tip line D of the upper to be improperly positioned. This arrangement further insures that the overlaying devices shall operate with the best results in securing the margins of the upper to the insole.

As shown in Fig. 3, the side gages 40 comprise vertically disposed fingers the lower ends of which are pivoted at 92 to ears 93 on a slide 94 which is movable in a vertical slideway comprising guiding faces formed at the inner sides of parallel fianges 95 on the casing 38 so that the side gages, after having performed their locating functions, may be lowered out of the way of the side wipers G8 and the overlaying devices 50 to avoid interference with the latter as will be hereinafter explained. The illustrated gage fingers 40 are formed at their upper ends with substantially horizontal faces 96 for engagement with the opposite marginal portions of the lower surface of the insole to cooperate with the toe rest 38 in supporting the insole and the last, and with upstanding lugs 98 (best shown in Fig. 3) for engagement with the opposite edges of the insole substantially in the plane of the tip line of the upper, if the upper has a toe tip, and for overlapping the adjacent edge portions of the sides of the last. These side gage lugs 98 function relatively to position transversely the forepart of the insole and the forepart of the last. The side gage fingers 40 are adjustable toward and from each other to'accommoda-te insoles and lasts of different widths and means is provided for adjusting the gage fingers, this meanscomprising two manually operable bell-crank levers I (see Fig. 4) which are pivoted at I02 to a portion of the casing 30 and are arranged with the free ends of their longer arms extending between and operatively engaging the gage fingers. As shown, the gage fingers 40 are held yieldingly against the arms of the bell-crank levers I00 by means of springs I04 (Fig. 3) acting upon extensions I06 of the gage fingers. The shorter arms I08 of the bellcrank levers I00 extend toward each other and are formed at their ends with gear segments IIO the teeth of which intermesh, the arrangement being such as to maintain the levers I00 with the ends of their long arms equidistant from a vertical plane which is centrally disposed relatively to the side wipers 48 and the overlaying devices 50, and consequently to maintain the side gage fingers in a similar relation to that plane so as to insure uniformity of action of the side wipers 48 and overlaying devices 50 upon opposite sides of the upper. For the purpose of operating the bellcrank levers I00 to adjust the side gage fingers 40 toward or from each other an adjusting screw I I2 is provided, the screw I I 2 extending through and having threaded engagement with blocks I I4 (see Fig. which are swiveled upon the long arms of the levers I00, the pitch of the threads cooperating with one of the blocks II4 being opposite to the pitch of the threads cooperating with the other block so that turning of the screw IIZ'in one direction will result in moving the levers I00, and consequently the gage fingers 40, simultaneously in opposite directions. The screw II2 extends outwardly through an opening in the casing 30 and is provided, outside of the casing, with a knurled head Hi3 by means of which the screw may be turned to effect a desired adjustment of the gage fingers 40.

It will be seen from the foregoing that a last having an upper and an insole loosely assembled therewith is supported, while the upper is being operated upon in this machine, by means of the heel rest 36 and the toe rest 38 and that the hori- I zontal faces 96 on the side gage fingers 40 assist in supporting the forepart of the last until they are lowered to make way for the side wipers 48 and the overlaying devices 50. It will also be seen that the forepart of the insole is located with its edge registering with the edge of the last bottom by means of the side gages 40 and the toe gage 42, that the last with the upper and the insole thereon is located lengthwise with respect to the operating instrumentalities by means of the toe gage 42, and that the last is located widthwise in position for the upper to be operated upon by means of the side gages 40. Moreover, the side gages 50, whatever their positions of adjustment, are located equidistant from a vertical plane centrally disposed with respect to the foredraw member 46 so as to insure that the foredraw member will act upon the central portion of the upper as well as to insure substantial uniformity of action of the side wipers and the overlaying devices upon opposite sides of the upper.

The foredraw member at (as best shown in Figs. 2 and 5) consists of a lever which is fulcrumed upon a horizontal pin I20 that is located somewhat below and forwardly of the toe of a last supported by the heel rest 36 and the toe rest 38. The foredraw lever 45 is curved upwardly and forwardly from its fulcrum pin I20 to overlie the toe of the last and its upper free extremity is provided with a pad I22 of soft rubber or other yieldable material adapted 'to conform readily to the curvature of the last-when pressed against the latter so as to secure firm frictional engagement with the upper without having any tendency to injure the latter. When the machine is idle the foredraw lever 46 is elevated somewhat above the position in which it appears in Fig. 2 to facilitate the placing of the last in position upon the toe rest 38. The lever 46 is swung downwardly by means of the foot treadle 52 to bring the pad I22 into the position shown in Fig. 2 for engagement with the upper, and thereafter the fulcrum pin I20 is moved by power in a direction lengthwise of the last to move the lever 46 bodily forward for the purpose of foredrawing the upper and tightening it about the heel of the last. To permit the fulcrum pin I20 to be moved as just described it is: supported by a yoke I24 which embraces the lever and is carried at the forward end of a plunger I26 which extends through and is adapted to slide within a horizontal bore in the bracket 80, the plunger being acted upon by a spring I 28 tending to move it in a direction to hold a shoulder I30 on the yoke I24 seated against the outer end of the bracket 80. As shown, the spring I28 is connected at one end to the plunger I26 and at its opposite end to an adjusting screw I32 which extends through an aperture in the casing 38 and is provided outside of the casing with a wing nut I34 which may be turned to vary the tension of the spring. For the purpose of swinging the foredraw lever I46 about its fulcrum pin I20 into and out of engagement with the work and moving the lever 48 bodily to draw the upper forwardly on the last the lower arm I36 of the lever 46 is connected by a rod I38 with the upwardly extending arm I40 of a three-arm lever which is pivotally mounted upon a fixed horizontal rod I42, the three-arm lever having a downwardly extending arm I 44 which carries a cam roll I 46 arranged to engage the periphery of a cam I48 on the cam shaft 56 and a second downwardly extending arm I50 which is connected by means of a rod I52 with the foot treadle 52. A spring I54 secured at its upper end to the casing 30 and at its lower end to the rod I52 tends to turn the three-arm lever I40, I44, I50 in a direction to hold the cam roll I46 in engagement with the cam I48, and to hold the foredraw lever in its normal elevated position. Upon depression of the treadle 52 the roll I46 is carried away from the cam I48 and the foredraw lever is swung downwardly to press the pad I22 into firm frictional engagement with the upper, after which continued downward movement of the treadle 52 will operate, through the treadle rod 60, to throw the clutch 58 and thus to start the operation of the machine under power. During the operation of the machine under power the roll I46 is engaged by the cam I48 and the foredraw member 46 is operated to tighten the upper upon the last.

As shown, the treadle rod 60 is connected at its upper end with a clutch-controlling lever I58 which is pivoted at I60, the upper portion of the rod 60 having a pin-and-slot connection I62 with the lever I58 arranged to permit the rod60 to move downwardly without moving the clutch-controlling lever I58 until after the foredraw pad I22 has engaged the upper. The clutch 58 is a clutch of the Horton type which is so well known that it need not be particularly described. It will be understood, however, that this clutch has friction rollers adapted rotatably to connect its two elements of which the outer element I64 (Fig. 1)

ispinned to the cam shaft 56 while the innerelement IE6 "is fixed to a "sprocket wheel I68 that :is carried by the cam shaft 56 and over which passes the sprocket chain 54. The friction rollers of the clutch 58 are normally heldout of operation by means comprising a controller ring I10 (Fig. 2) provided with a shoulder I12 arranged to cooperate with the hooked extremity of the clutch controlling lever I58. The clutch-controlling lever I58 is held in operative position by means of a spring (not shown). When the lever I58 is momentarily disengaged from the controller ring I10 by depression of the foot treadle 52 the clutch 58 operates to imp-art asingle rotation to the cam shaft 56 and the cams thereon and is then arrested by engagement of the lever I58 with the shoulder I12. As soon as the clutch is thrown into operation the cam I48 moves the three-arm lever I40, I44, I50 in a counterclockwise direction and, through the rod I38, moves the foredraw lever 46 bodily toward the left, the plunger I 26 sliding outwardly against the tension of the spring I28 to permit such movement of the lever 46 to take place. During this bodily movement of the lever the latter is constantly urged about its fulcrum I20 in a direction such that the foredraw pad I22 is continually held in firm frictional engagement with the upper.

The side wipers 48 comprise pads of soft rubber or the like which are secured to the inwardly turned upper ends of two levers I18 arranged one at either side of the forepart of the last so that the pads will engage the upper approximately in the plane of the tip line, the levers I18 having inwardly turned lower extremities which are pivoted at I to ears I 82 which project in opposite directions from a slide I84 that is mounted below the slide 94 for up-and-down movement in the guideway formed by the vertical guiding faces 95 already referred to. Substantially midway between the upper and lower ends of the levers I18 these levers are connected together by means of a spring I86 which tends to swing the levers toward each other, the inward movements of the levers under the influence of the spring being limited by engagement of rolls I88 carried by the levers with inclined cam faces I90 formed on plates I92 which are rigidly secured by means of screws I94 to the outside of the casing 30. The slide I84 is connected by means of a link I86 with the upper end of a cam lever I98 (Fig. 2) which is pivotally mounted upon the rod I42 and which carries at its lower end a cam roll 200 arranged to engage the periphery of a cam 202 on the cam shaft 56. A spring 204, connected with the lever I98, tends to swing the lever in a direction to hold the slide I84 in its upper position and to hold the roll 200 against its cam. When the machine is idle the levers I18 occupy the positions shown in Fig. 3 with the side wipers 48 spaced upwardly and outwardly with respect to the upper on the last. Upon rotation of the cam shaft 56 the cam 202 operates to rock the lever I98 in a direction to lower the slide I84 and to move the side wiper levers I18 downwardly. As the levers I18 move downwardly the spring I86 operates to swing the levers inwardly about their pivots I80 under the control of the cam faces I98 until the side wipers 48 engage the upper and are held in firm frictional engagement therewith by means of the spring I86. The cam faces I90 are designed to cause the side wipers 48 to engage the upper at points spaced outwardly from the foredraw member 46 and as the levers I18 continue to move downwardly the spring I86 yields to permit the side wipers to separate as required to follow the curved contour of the last while serving to maintain frictional engagement of the side wipers with the upper so as to wipe the upper downwardly over the opposite sides of the toe portion of the last and thus to tension it transversely in the vicinity of the tip line.

As shown, the overlaying devices 50 are in the form of rolls, the rolls being carried in the forked upper extremities of two plungers 200 which are guided for sliding movements in sockets 208 (Fig. 3) formed in the upper arms of two levers 2 I 0 which are mounted for swinging movements toward and away from each other about fixed pivots 2 I2. The lower portion of each plunger 206 is bored as indicated at 2 I4 to receive a spring 2| 6, the upper extremity of which bears against the uper end of the bore 2M and the lower end of which is seated against the bottom of the socket 268. Upward movement of each plunger 205 in its socket 208 is limited by means of a stop screw 2I8 carried by the plunger and arranged to engage the lever 2 I 0 at the upper end of a slot 220 in the lever. The levers 2I0 extend downwardly below their pivots 2I2 and are connected together at their lower ends by means of two

toggle links

222 and 224, the outer ends of which are pivoted at 226 to the levers 2H] and the inner ends of which are pivotally connected with each other by means of a screw 228 which serves also to secure the toggle links pivotally to the slide 94 which also carries the side gage fingers 48. The slide 94 is connected by means of a link 230 (Fig. 2) with one arm of a lever 232 that is mounted to turn on the rod I42, and the other arm 234 of which carries a cam roll 236 arranged to bear upon the periphery of a cam 238 on the cam shaft 55. A spring 240 (Fig. 4) connected with the lever arm 232 tends to hold the slide 94 in its uppermost position and to hold the roll 236 against its cam. The cam 238 opcrates to lower the slide 94 and to straighten the

toggle

222, 224, the straightening of the toggle moving the overlaying devices inwardly to press the margins of the upper against the insole and the lowering of the slide 94 withdrawing the side gages 40 from the paths of the side wipers 48 and the overlaying devices 50.

To prepare the upper of a tennis shoe orsneaker to be operated upon by the lasting machine ID the operator of the above described as sembling machine, after having first placed an upper and an insole in loosely assembled relation upon a last, presents the last and the parts there on right side up to the assembling machine, po-

sitioning the last so that the toe and heel portions of the insole rest upon the toe rest 38 and the heel rest 36, respectively, with the toe of the last beneath the foredraw member I22 (which is elevated somewhat above its work-engaging position) and thrusting the last forwardly to engage the edge of the insole and the edge of thelast bottom with the toe gage 42 and with the side gages :10. It will be understood that the heelrest 36 has been previously adjusted vertically by manipulation of the nut I0 into positionto cooperate properly with the toe rest 38 in supporting the last and that the

gages

40 and 42 have been adjusted by means of the screws I I2 and 86, respectively, as may have been required in accordance with the size and style of the particular last being operated upon. It should also be understood that the lower margin of the upper has previously been coated on its inner side with cement which will cause the upper to become firmly secured to the insole when pressed against the insole by the overlaying rolls 50. The

gages

40 and 42 project upwardly between the upper and the sides of the last, the toe gage 42 functioning to aline the edges of the insole with the edge of the last bottom at the tip of the toe and to locate the last and the parts thereon lengthwise in position to be operated upon, while the side gages 40 aline the opposite lateral edges of the insole and the last bottom at the forepart of the last and serve to locate the forward portions of the last, the upper, and the insole widthwise in proper relation to the operating instrumentalities of the assembling machine.

The work having been presented to the assembling machine and positioned thereon as above described, the operator depresses the foot treadle 52, thereby causing the foredraw lever 46 to be rocked by foot power about its pivot I20 to lower the pad I22 into frictional engagement with the upper, in which position the member I22 cooperates with the toe rest 38 in clamping the work so as to prevent the last and the insole from being displaced while the upper is being operated upon. The shoulders 96 on the side gage fingers 40 also cooperate with the pad I22 in the initial clamping oi the work. As the treadle 52 is moved further downward by the operator the clutch 58 is tripped and the machine starts to operate under power. At the beginning of its cycle of operations under power the mecha, nism operated by the cam I48 functions to move the pivot I20 oi the foredraw lever 40 forwardly relatively to the last, while at the same time exerting a force tending to rock the lever 46 about its pivot I20 so as to maintain the pad 122 in efiective holding engagement with the upper. As the downward pressure on the pad I22 is maintained and as the pad I22 moves forwardly of the last under power as a result of the forward movement of the pivot I20, the upper is drawn forwardly toward the toe of the last and is thus tightened about the heel end and along the sides of the last. During the above foredraw movement of the member I22 the mechanism operated by the cam 202 lowers the side wipers 48, the spring I moving the side wipers inwardly, under the control of the cam faces I90, into yielding frictional engagement with the upper at opposite sides of the foredraw lever 56, and causing the wipers yieldingly to wipe the upper downwardly over the forepart of the last to tension it widthwise of the last, and finally holding the side wipers pressed against the upper in the positions in which they appear in Fig. 6 to maintain the upper in tensioned condition during the laying of its lower marginal portions over the insole. During the downward movements of the side wipers G8 the mechanism actuated by thecam 238 starts to straighten the

toggle

222, 224, thereby moving the overlaying rolls 50 toward each other and at the same time lowering the slide 94 and the side gages 40. The side gages 40 are lowered to positions sufliciently below the insole to avoid interference with the operative movements of the side wipers and the overlaying rolls. The overlaying rolls engage the downwardly projecting margins of the upper and, after the side wipers have completed their downward Wiping movements, the overlaying rolls move inwardly to the positions shown in Fig. '7, during which movements they lay the upper. margins against the lower face of the insole and press them firmly against the insole so that the portions of the upper margins engagedby the rolls will be secured to the insole by means of the cement on the inner sides of the margins of the upper. Thus the upper is securely heldin its tensioned condition. upon the last so that it will not become displaced during the transfer of the last to the lasting machine. During the latter part of the cycle of operations of the assembling machine the operative parts of the machine ar returned to their starting positions to facilitate the removal of the work which has been acted upon and permit the presentation of a new piece of work to the. machine. The foot treadle having been released by the operator shortly after the starting of the cycle of. operations, the clutch lever I58 is returned into position to function, after the cam shaft 5? has completed a single revolution, to stop the machine with the operative parts in the positions shown in Fig. 1 ready for the performance of. another assembling operation.
