ASSEMBLING AND LASTING MACI-TINE.

Application filed December 30, 1918. Serial No. 268,809.

To all whom it may concern:

Be it known that I, VVILLIAM G. CHENEY,

a citizen of the United States, residing at Marlboro, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Assembling and Lasting Machines, of which the following description, in connection with the accompany ing drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates tomachines for assembling shoe uppers upon their lasts and for layingover the upstanding margins of the uppers about the ends of the shoes, particularly the heel ends, into contact with the innersoles. The invention is herein illus trated as embodied in a machine particularly adapted for use in the manufacture of a type of shoe in which the margin of the upper is secured to the innersole in lasted position by adhesion, the machine shown having means for holdingthe upper in as sembled relation upon a last and for laying the margin of the upper in contact with the heel seat of the innersole. It is to be understood, however, that in many of its aspects the invention is not limited to machines for operating upon this particular type of shoe nor to machines including both assembling means and lasting means. I

Well known examples of shoes of the type above mentioned which aremade in large numbers at the present time are so-called sneakers and tennis shoes, which usually comprise an upper of fabric and a sole of rubber or rubber composition. In the manu facture of these shoes it is the commonpractice to use an innersoleof such character as to material and thickness that it is comparatively yielding to any pressure such as might tend to distort it, for example, the pressure of inwardly moving wipers of the usual type. The innersoles are frequently made orsocalled rag stock comprising a mixture of unvulcanized rubber and scraps of cloth or other waste fibrous material. The inner face of the margin of the upper is coated with cement, and in the lasting ofthe shoe, the margin of the upper is pressed against the innersole to render the cement effective to hold the upper in lasted position. Subsequently an outersole is cemented to the shoe and the shoe is vulcanized.

Heretofore in the manufacture of suchshoes the operation of assembling the upper upon last and then laying over the margin of the upper by a rocking and wiping movement of his thumb or fingers. This hand work is exceedingly laborious and, by reason of the consequent fatigue of the workmanand the general unreliability of hand operation, uniform results in the course of a days work are difiicult to obtain. As a consequence the manufacturer finds in his product a large number of defective or reject shoes which haveto be disposed of, if at all, at a greatly reduced profit or at a loss. Furthermoreit is practically impossible for the workman to hold the upper properly to the last while at the same time applying sufficient overlaying pressure to cause proper adhesion between the upper margin and the innersole. An object of this invention is to provide a machine for doing this work more rapidly than it can be done by hand and for overlaying and pressing the upper into contact with the'innersolein such manner as to avoid danger of wrinkling or displacementof the inn'ersole'and to obtain firm adhesion of the upper to the innersole.

A feature ofthe invention consists in .an organization including a shoe support movable to carry the shoe into and out of opera tive relation to the machine and lasting instrumentalitios which act when the shoe is in operative position to lay the margin of the upper over the shoe bottom and to force the margin into contact with the shoe bottom, the said instrumentalities in the construction shown being arranged to effect the laying over and downward pressure WlthOUhtUQPllcation of pressure in the direction of the plane of the sole such as would tend to cause buckling or displacement of the innersole. As shown herein, the lasting instrumentalities consist of rolls arranged about the periphery of the heel seat in close proximity to each other so as to engage substantially all portions of the margin.

Another feature of the invention consists in a novel organization comprising a roll or rolls for operating at an end of the shoe, herein shown as the rear end of the heel seat, and a roll at each corner of the shoe end with operating means arranged to operate the end rolls at one time in the cycle and the to operate to .do their work. This construction avoids any interference between the action of the end and corner rolls and enables the action of the end rolls to overlap the action of the corner rolls or vice versa if desired.

A further feature of the invention consists in a series of separate overlaying means arranged along each side of the heel seat including the portion that curves inwardly toward the shank, with operating means to effect inward movement of the overlaying means simultaneously. Preferably the overlaying means on each side of the shoe next to the shoe shank are given a component of movement toward the rear end of the shoe in addition to their inward movement in order better to take care of the fulness in the upper at the inwardly curved shank portions. As shown herein, the members of each series are given progressively greater movement from the rear end toward the shank. This enables the overlaying means, in their inward movement, to act on the heel seat in the narrower portions adjacent to the shank and increases their movement of withdrawal from the shoe to afford room for movement of the shoe out of operative relation to the overlaying means. Preferably the overlaying means at the sides of the shoe consist of rolls each independently mounted, themounting including a yielding element to enable them to yield upwardly and press evenly upon the overlaid upper.

Another feature of the invention consists in an organization comprising means for holding the upper and counter in assembled relation closely to the contour of the last at the rear end of the last in combination with rolling means for lasting in the margin of the upper extending above the shoe bottom. The upper holding means, as herein shown, comprises a band which is arranged to be closed by pressure of the shoe rearwardly into the band and the rolls are arranged to act above the plane of the upper edge of the band.

A. further featureof the invention consists in a machine organized for power operation having upper overlaying means and means for effecting conforming pressure about the end of the shoe to force the upper into contact with the side and end of the last with means responsive to pressure of the shoe into the upper conforming means for effecting power operation of the overlaying means. Preferably and. as shown, the upper conforming means comprises a band which is bodily movable to effect power operation of the machine.

Still other features of the invention consist in a construction and arrangement of the roll mounting for inward and outward swinging movement about a pivot over the shoe bottom, in novel means permitting bodily yielding movement of. the pivot when movement of the rolls is limited, in a novel construction of the rolls, and in various details of construction and combinations of parts, all of which will be described with reference to the accompanying drawings and pointed out in the appended claims.

Fig. 9 is a PGISPGClZlX G view of the rear end of the shoe after it has been operated upon by the machine.

Referring to Fig. 1 of the drawings, the numeral 2 indicates the column of the machine near the base of which is pivoted at f a jack post 6 in which is telescoped a jack rod8. The jack rod extends through a slot in a lever 12 and carries an adjustable sleeve 10 which rests on the upper face of the lever 12. The lever 12 is fulcrumod at 14 to a bracket on the column 2 and is lifted at the proper time in the cycle of the machine by an edge cam 16 (Figs. 5 and 6) which operates through a lever 1.8 fulcrumed at 19 (Fig. 5) to exert an upward pull on a rod 20 which is yieldingly connected to the lever 12 through a spring 22. The sleeve 10 is threaded on the rod 8 so that it may be turned to adjust it up or down on the rod. To limit the upward movement of the lever 12, an adjustable stop 24 is provided. which is in the form of a screw threaded'through a lug on the machine frame. On the upper end of the rod llll) 8 is a heel pin 26 upon which is placed a last and shoe the heel seat of which is to be lasted.

While the rod 8 is in its outwardly swung position, a last with a shoe upper and innersole placed thereon is placed upon the pin 26. The operator, having arranged the upper in proper relation to the last and innersole, swings the shoe toward the machine. In this movement the rear part of the shoe is embraced by a band having the construction shown in Fig. 3. The band comprises a lining 30 of suitable material, for example, leather, which is backed up by a chain 32 connected at its

ends

34 and 36, respectively, to arms 38 and t0 of bell crank levers pivoted at 42 and 46 to a supporting head 48. The other arms 50 andv52 of the bell crank lever are connected together to the central portion of the chain 32. By this construction rearward pressure of the shoe against the band causes first the end of the band and then the sides to be pressed against the end and sides of the shoe to force all portions of the rear part of the shoe upper into conformity to the last and to hold them in assembled relation during the subsequent operation of laying the margin of the upper which extends above the plane of the sole into contact with the sole.

After the band has been fully closed against the rear part of the shoe it is arranged to have a movement bodily to bring the shoe into proper relation to the devices for laying the upper against the shoebottom and this movement is preferably utilized to startthe machine. To effect this the band supporting head 48 has a stem 54 (Fig. 5) mounted in the frame 56 of the head of the machine for inward and outward move ment and is held outwardly by a spring58 which spring is sufliciently stiff to with stand the rearward pressure of the last and the shoe into the band until the ban-d has been tightly closed against the rear part of the shoe and then to allow bodily movement of the band by compression of the spring 58. A rod 60 is connected to the stem 54 and extends rearwardly of the machine head where there is connected to it a strut 62 carrying a rod 64. Mounted on the rod 64 is a block 65 in which is mounted for vertical movement a pawl 66 which is pressed upwardly by a spring 67 and has an inclined upper face. The block 65 is preferably guided for horizontal movement by a rod which extends forwardly therefrom and slides in a hole in a boss 69 on the machine frame. The pawl 66, when pawl 66 engages the lever 68 and causes it to remove the pin 72 from the lug 74 allowing the clutch to go in and the machine to start. Rearward movement of the pawl 66 is sufficient to pass the end of the lever 68 and allow the stop pin 72 and lever 68 To relieve the operator of the exertion of holding the shoe in the band and to exert greater rearward pressure of the shoe into the band than can conveniently be exerted by the operator, means shown in Figs. land 5 is provided for locking the shoe in the band and exerting additional rearward pres-- sure thereon during the operation of the machine. For this purpose a bar 80 is pivoted at 82 to the rod 8 and extends through the column 2 to the rear of the machine where it is supported by a yoke 84 attached to the lower end of a lever 86 fulcrumed at 88 to the head 56 and having on its upper end a roll which contacts with the edge of a cam 90 on the shaft 17. 'On the lower end of the lever 86 above the, bar is pivoted at 92 a pawl 94. Below its pivot the pawl 94- is engaged by a pin 96 on the machine frame which,1n the normal or stop position, holds the pawl raised so that it will not engagc teeth 98 formed on the upper face of the arm 80. When the machine is started the cam 90 operates tomove the pawl rearwardlyaway from the pin 96 and allow it to engage the teeth 98 whereupon further movement of the lever 96 will draw 'the rod 8 rearwardly and force the shoe more tightly into the band.

To hold the 'innersole firmly against the last during the jacking and lasting'operations, a yielding sole presser is provided which is organized to permit movement of the shoe while in engagement with it without tending substantially to displace the innersole relatively to thelast. In a forward projection 100 of the fran'ie 56 a plunger 102 is mounted for vertical movement and is held depressed by a spring 103. In the lower end of the plungeris mounted a roll 104 on an axis extending transversely of the shoe. The" roll 104 holds the innersole against the last while permitting substan tially free movement of the last and innersole under it longitudinally of the shoe.

The lasting instrumentalities by which the upstanding margin of the upper materials is laid over the bottom of the shoe and lit) pressed into engagement therewith, will now be described. These instrumentalities include means for operating upon the upper at the rear end of the heel seat and separate means preferably operating subsequently, for laying over the upper at the corners and sides of the heel seat. The first means comprises a pair of

rolls

110, 110 arranged on axes inclined to each other, as shown in de tail in Fig. 2. The rolls are mounted in a block 112 (Fig. 5) having a stem 114 extending lengthwise of the shoe through a block 116, the stem permitting rocking movement of the rolls to insure their bearing with equal pressure upon the shoe bottom. On the block 116 is a spindle 116 extending substantially ver tically of the shoe bottom through the lower portion of a lever 120. The spindle 118 is reduced for a portion of its length to accommodate a spring 122 located between the shoulder formed by the reduction of the spindle and the upper portion of the lever 120 through which the spindle extends and is provided with nuts 124; which may be set tomaintain the spring 122 at anydesired degree of compression. The spring 122 allows the rolls 110 to yield upwardly as they pass over the shoe bottom and causes them to apply yielding pressure to the upper as they roll it down against the innersole.

The lever 120 extends through an opening 125 in the projection 100 which opening is elongated lengthwise of the shoe. The lever 120 is fulcrumed at 121 between the arms of a yoke 126 which yoke has a cylindrical portion 128 mounted for rocking movement in a boss 130 on the frame 56. The inner part of the portion 128 is reduced to accommodate a spring 132 located between the shoulder formed by the reduction and the boss 130, the reduced partbeing extended through the boss and provided with a nut 134 and washer 135 by which the spring .132 may be maintained at any desired degree of compression. This construction provides a rearwardly yielding pivot for the lever 120 which may come into action when move ment of the rolls 110 over the shoe bottom is arrested by a gage or step 136. This stop has a stem 137 mounted in a split clamp 138 on the block 116, the clamp being operated by a screw 1410 (Fig. 2') to hold the stem and stop in different positions of adjustment. The stop 136 engages the rear end of the band and may be set to limit movement of the rolls over the shoe bottom at the desired point. Above its ivot 121 the lever 120 extends upwardly and rearwardly and has an inclined or offset portion 142 in which is a ball socket receiving the spherical end of a link 1 14, the usual ball cap 146 being pro vided to retain the end of the link in place. The other end of the link 1 1 1 is similarly formed and mounted in the forward arm 1&8 of a lever (Figs. 5 and 6) fulcrumed at 149 to the frame 56 and having on its rear arm 150 a cam roll engaging a path 152 in a cam block 15 1 on the shaft 17. The cam acts through the lever 150, 1 18 and link 1&4: to push downwardly on the inclined or oilset portion 142 of the lever 120 to cause the lower portion to swing inwardly over the shoe bottom. The rolls 110 are thus caused to engage the upwardly extending margin of the upper at the rear end of the shoe and roll it into engagement with the innersole bottom at the rear end of the heel seat and, in the type of shoe for which the present invention is particularly designed, causing the upper to adhere to the surface of the innersole, the rolls acting yieldingly through the spring 122 upon the stock and being arrested in their overlaying movement by the stop 136. When this occurs. further movement of the lever 1418 taken up by the rearward yielding of the yoke 126 against the spring 132 as described.

At the corners and sides of the heel seat the upper is acted upon by independently mounted single rolls 157 156 (Fig. 7) which are actuated simultaneously in. timed relation to the action of the end rolls 110. In the construction shown herein, the machine is organized to cause the rolls 110 to act on the end. of the shoe and then withdraw rearwardly to permit operation of the corner rolls. It is recognized, however as within the invention to arrange the end and corner rolls for operation in other timed rela tion. The construction and means for operating one of the side rolls as shown in Fig. 4: will now be described. it being understood that the corner rolls 157 and side rolls 156 are all of similar construction and are operated at the same time by a single operating lever. Each of the side rollsv 156 and corner rolls 157 is mounted for rotation between bifurcations of a member 158 having a stem 1.59 mounted to rock in a block 160 having a spindle 161 extending upwardly through a bore in a depending portion or arm of a lever 162. The spindle 161 is reduced for a portion of its length to accommodate a spring 16 1 arranged between the shoulder formed by the reduction and the upper portion of the lever arm 162. the reduced portion of the spindle being extended through the lever and provided with nuts 166 by which the spindle is retained in place and the spring 16 1 maintained under a suitable degree of compression. The lever 162 is fulcrumed at 170 to a yoke 172 which. embraces an outwardly inclined or ofliset portion 174 of the lever 162 and is formed with a cylindrical portion 173 rotatably mounted in a boss 176 formed on a forwardly exupwardly and tending U-shaped portion 178 of the frame portion 173 andthe bottom of the hole in the boss is a spring 184:. The nut 182 maintains the spring under a 1 suitable degree of tension and the pressure of the washer 183 on the frame produced by the tension of the spring holds the yoke 172 frictionally against free turning movement. The upper portion 17 1 of the lever 162 has an inclined face 186 in which is a ball socket to receive the spherical end of a link 188 the opposite end of which is similarly mounted in one of the branches 190, 191 (Fig. 6) of the U-shaped end of an arm 192 of an operating lever fulcrumed at 149 on the same shaft as the lever 148 and having an arm 194: (Fig. 6) operated by a cam path in a cam block 196 on the shaft 17. Depression of the

forward branches

190, 191 of the lever by the cam 196 causes the corner rolls 157 and the side rolls 156 which are all organized similarto the one described, to move over the shoe bottom, the pressure normal to the shoe bottom being rendered yielding by the springs 164.

Movement of the overlaying means or rolls over the shoe bottom is limited by stop-s 197 having stems adjustably held in split clamps on the blocks 160. The stops 197 engage the outer face oftheiupper portion of the band 30 and limit movement of the overlaying means over the shoe bottom. When the stops 197 engage the band further movement of the operating

lever

192, 194 is permitted by reason of the yielding conncction including the springs 184: which permit outward bodily movement of the yokes 172 and pivots 120 in response to the pressure of the link 188 on the offset-174, the inclined arrangement of the links causing them to exert a component of pressure outwardly axially of the portions 173 andv against the springs 184 which will yield to take up the movement of the lever arm 192 including the

branches

190, 191 in excess of that required to carry the overlaying means over the shoe bottom as far as permitted by the stops 197. It will. be observed that the links 188 and'offset 174 constitute a toggle in the operating connections for the overlaying means orrolls which toggle is bent to effect movement of the overlaying means.

By reference to Fig. 7 it will be observed that the rolls 157 are arranged one at each corner of the heel seat and a series of three rolls 156 at each side of the heel seat and also that the cylindrical portions 17 3 of the yokes 172 are arranged with their axes extending in directions substantially radially of the curve of the shoe bottom so that the c rner and side rolls will move over the shoe bottom wlth their axes substantially parallel with the portion of the edge of the last adjacent to which they actor parallel with atangent to the said portion of the edge. The rolls which engage the upper adjacent to the shank of the shoe may, however be so inclined to the edge of thelast asto have a component of movement rearwardly of the shoe to assist in gathering the stock toward the rear of the shoe and causeit to be tightened in the shank portion of the shoe.

It will be noted also that the rolls which are located toward the shank of the shoe, in order to clear the shoe when retracted, should have greater total movement than the rolls at the rear end of theshoe, for instance, the corner rolls. This is effected in the construction shown by reason of'the fact that the forward ends of the

branches

190, 191, which communicate movement to the forward rolls, receive greater movement from the cam than the other portion of those branches from which movement is communicated to the rearward rolls, that is, the movement communicated to the rolls is progressively greater according as their operating links 188 are connected to the lever 192 at greater and greater distances from the pivot 1 19 of the lever. The'rolls 156 and 157 may, with advantage, have the formshown in Fig. 8 where a roll 156' is shown which has its end corners rounded and. its acting face slightly concave. The rounded corners prevent the ends ofthe' roll from digging into the work and the conoaved faces enable the rolls to obtain a better bearing against the convex edge of the last as they roll the stock into place.

Althoughthe operation of the various parts of the machine has been given in connection with the description of the mechanism, itwill be of advantage in, understanding the operation otthe machine asa whole and in elucidating certain details. briefly to summarize the operation of the machine. k a l The jack is swung outwardly and a last It will be understood that in rubber work.

for which the machine is especially though not exclusively adapted, the inner face of the margin of the upper will be coated with cement and the innersole will. be of rubber having an innersole laid thereon and cow ered by an upper, is placed upon the pm 26.

iii

will engage the roll 104i which determines its vertical position. Theinnersole is held upon-the last bottom by the operators lin gers andth'e roll 104 permits free movement ofthe shoe without tending materially to displace theinnersole on the last.

Inward pressure on the shoe causes the band -first to press'on the rear end of the shoe and then to close against the side of the shoe, thus holding the upper ti 'htly in assembled relation upon the last. Continued pressure on the shoe effects bodily movement of the band to trip the clutch and start the machine. The lever 86 is operated to cause the pawl 94; to engage one of the teeth 98 to lock the shoe against outward movement and to apply additional inward pressure to theishoe through the spring 80. Substantially at the same time the rod 20 is operated to lift the lever 12 through the spring 22 and apply upward pressure to the last to sustain the shoe during the operation of the lasting instrumentalities. Next the lever 1-18, 150 is operated by its cam to cause the end rolls 110 to pass forwardly over the shoe bottom at the rear end of the last and to lay aportion of the upper against the inner sole and cause it to adhere thereto. The rolls 110 are then withdrawn or begin to withdraw and the corner rolls 157 and side rolls 156 are caused by operation of the

branches

190, 191 of the lever 192, 19 1 to lay the remaining portions of the upper about the heel seat into firm contact with the innersole and cause them to adhere thereto, the relative timing of the movement otthe end and corner rollsbeing such as to avoid any interference between them. As the rolls approach their limit of inward movement over the shoe bottom the

stops

136, 137 engage the upper margin of the band 30 and cause it to press tightly against the shoe additionally to shape the upper to the last. When further movement of the. rolls is an rested by the stops the further movement of the operatinr mechanism is taken up by outward movement of the

cylindrical members

128, 178 against the springs 132. 184. The condition of the shoe after the opera tion of the machine upon it is represented inFig.8. p

The levers 162 which carry the corner and the side rollscan turn on the cylindrical members 173 to permit relative movement of the rolls in the direction. of the last edge in case there should-be interference of one roll with another when they reach their in ward positionover the shoe bottom which may occur in case a small shoe is being treated.
