Application filed March 4, 1918.

lowing description, in connection with the.

accompanying drawings is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the lasting ol hoots and shoes.

(he invention illustrated as embodied in a machine especially designed for lasting shoes ol the type in the manufacture of which the shoe upper is temporarily secured in lasted position on an innersole by adhesion and the various bottoming materials of the shoe are subsequently permanently secured by vulcanization, the inner-sole for the shoe usually consisting of an inexpensive vulcanizable material termed rag-stock and having an adhesive coating applied to its surface.

l-lereto'fore, such shoes have been lasted almost entirely by hand, the customary man ner being for the operator to assemble the innersole, together with the shoe upper, upon a metal last and then to bring the marginal portion of the upper into adhesion with. the adhesive surface of the innersole with his lingers, subsequently rolling the over aid marginal portion of the innersolc by a relatively heavy hand roller to insure proper adhesion between the margin of the shoe upper and the innersole.

This method of lasting vulcanized rubbe sole shoes is not only exceedingly laborious and slow, but renders extremely ditiicult the obtaining of the desired precision and uni formity in the quality of the work. Moreover, it is diilicult to obtain sufiicient tension of the shoe upper about the last with the fingers to draw and shape the shoe u pper to the conformation of the last, this latter disadvantage having been largely responsible for previous inability of? the shoe manufacturer to produce a vulcanized rubber sole shoe having the style and appearance characteristic of leather shoes.

A particular object of the present invention is to provide a lasting machine espe- Serial No. 220,242.

cially adapted for lasting rubber sole shoes, by the use of which such shoes may be lasted more elliciently and with greater uniformity than heretoforewhich shall materially reduce the cost 0' the lasting operations and which shall have the greatest possible output capacity consistent with satisfactory work.

With these and other objects in view and in accordance with important features oi the invention, the illustrated machine organization comprises a lasting means con-- l'ormable to the sides oi? a last and lniving an approximately sole-shaped margin constructed and arranged for operative engagement with the margin of the upper of an unlasted shoe completely around the shoe and operating upon relative movement oithe lasting means and the shoe substantially in. the direction Of the height of the shoe to wipe the upper up the sides of the shoe toward the shoe bottom under tension and to overlay the margin. of the tensioned shoe upper upon the shoe bottom in final lasted position.

In the illustrated en'ibodiment of the in vention, the lasting means comprises a yielding and resilient shoe receiving pouch or matrix of a shape approximately complemental to the sides of a shoe and constructed and arranged first to be moved into tension applying relation to the shoe, the side walls being then converged into position to oven lay the margin of the tensioned upper into adhesion with the innersole. Since the last-- ing device is constructed. and arranged to act upon substantiallyall portions of the unlasted shoe during its operation, a single shoe lasting operation only is required. to last the shoe, thus insuring a more uniihirm quality of lasting than if separate portions of the shoe, as, for example, the toe or the heel were lasted by independent operations, and also the lasting operation may be per formed more quickly and with less labor cost than heretofore.

As herein shown, the application of ten sion to the shoe upper by the relative movement of the lasting means and the unlasted shoe is effected by a construction and arrangement of means such as to force the shoe into the lasting matrix, thus causing the matrix to wipe the shoe upper up the sides oi? the last and preferably, owing to the extensible and conformable character of'the matrix herein provided, also effecting an extension or stretching of the matrix while it is in conformation with the sides of the shoe so that it produces a frictional drag upon the shoe upper sufficient to conform the upper to the last and to eliminate any undesirable wrinkles and also to take out the stretch in the upper about the last.

Another important feature of the'inven' tion resides in the provision for varying the relative movement of the shoe and the lasting matrix whereby the shoe is forced upwardly .after its initial depression to bring the overlasted margin of the tensioned upper into proper adhesion with the innersole and is then finally depressed into a position to allow the lasting matrix to free itself from the shoe without disturbing the lasted condition of the upper.

In accordance with still another feature of the invention, the construction and arrangement of the organization for applying tension to the shoe upper and for laying the margin of the tensioned upper into lasted position on the innersole are such as to cause the lasting means to produce a uniform and proportional application of tension'to all portions of the shoe upper about the last substantially simultaneously and also a similar application of tension to uppers of shoes of a Wide range of sizes and shapes so that the lines of the shoe are consistent with the particular style of the shoe being lasted.

A further feature of the invention resides in the novel construction and the arrangement of the mechanism for actuating the lasting means whereby an initial relative adjustment of 'the lasting device may be effected in accordance with the requirements necessitated by a change in the size or style of the shoe to be lasted. Preferably, and as herein shown, such initial relative adjustments of the lasting device, while cffect-ing a symmetrical adjustment of one portion of the device, as at the toe thereof, are independent of the adjustment of other portions of the device. By reason of this relative adjustment between each end of the lasting means, the lasting force employed in lasting the toe or heel end of the shoe may be varied to meet certain abnormal conditions in the particular shoe to be lasted, for example, a shoe having extra box toe or heel stiffener materials.

In accordance with a still further feature of the invention, the lasting means in the illustrated construction is constructed and arranged to be caused to overlay the margin of the tensioned upper upon the shoe bottom in final lasted position upon actuation of the lasting means during its movement relatively to the shoe and preferably during the process of stretching in the upper tensioning operation in such manner as to converge the lasting means inwardly and downwardly over on the shoe bottom, this converging movement of the lasting means being complen'iental to its upward upper tensioning movement so that the shoe upper is maintained continuously under the tensioning action of the lasting means as it is operated to overlay the margin of the upper over on to the shoe bottom.

It will be noted that the operation of the lasting device, first against the side faces of the shoe in the direction of the height of the shoe and then, diiagmially over on to the shoe bottom by a continuity of operative movement, is substantially identical with the action of the fingers of an operator in lasting the shoe by hand.

Other objects and features of the invention will be apparent from the following description when considered in connection with the accompanying drawings and the invention will be defined in the appended claims.

The machine herein shown as illustrating a preferred embodiment of the invention comprises a main frame 52 having an overhanging head portion on which is mounted a reciprocatory shoe engaging ack.

This jack comprises two lmigitndinally adjustable posts 4 and O for engaging a shoe bottom at the forepart and the heel respectively, each post being adjustably keyed by means of thumb screws 8 on a horizontal shaft 10 which is held in a bearing 11 provided on the forward end of a lever 12 fulcrumed at 14 in the head of the machine frame 2. The lower end of each of the posts 4 and 6 is provided with four radially projected spring fingers 16 (Fig. 7) which are adapted, together with the end of the post, to

therefore, not shown herein in detail.

engage the bottom of an unlasted shoe and exert a downward pressure upon the shoe while maintaining the shoe bottom in a substantially horizontal lane. The spring fingees 16 which extent toward the marginal portions of the innersole serve especially to render it certain that said marginal portions will not be pushed back or raised when the margin of the yieldable pouch hereinafter described is carried to the position shown in l ig. G. herein shown, the jack is reciprocated to exert a downward pressure upon the shoe by a manual or treadle operated means and also by a power controlled means, the manual means preferably effecting an initial operative movement of the jack and the power controlled means accomplishing the final (uperation of the jack. The initial manual operation of the jack is effected through a treadle rod 18 which is connected 20 to the rear end of the lever 1:2 and to the rear end of a lover of the first class which located in the base of the frame and constitutes the treadle lever. The power con trolled operation of the jack is effected by a cam 22 on a main driving shaft 24L disposed in the base of the frame 2. The shaft 24.- is driven by a fast pulley 26 on a shaft 528 which transmits power through a bevel gear 3) fast thereon to a co-operating beveled gear 532 which has a single revolution clutch connection with the shaft 24-. The clutch may be of any well known design and it is, The operation of the clutch is preferably occasioned at a infedetermined time in the manipulation of the manually operated treadle lever by connections between the treadle rod 18 and the clutch comprising a bell crank 36 pivoted at 38 to the frame One arm of thisbell crank ispivotally connected at 4-0 to the treadle rod 18 and the other arm 42 has a pin and slot connection with the upper end of a lever 4: 1 which fulcrumed on a stud 46 in a boss on the frame 2. Pivotally mounted at 4:? on the side of the lever 4:4. is trip latch 4:8 which is held in operative position by a spring -19 and is arranged to engage a boss 50 provided on the side of a lever This lever is also fulcruined at its lower end on the stud 46 and has its upper end as sociated with the clutch mechanism in such manner as to cause the pins 54L, if a pin type of clutch as herein indicated is used, to connect the continuously rotating gear 32 to the main driving shaft 24. As thus provided, the initial movement of the jack downwardly is effected by depression of the foot treadle and subsequent movement of the treadle rod 18 iiipwardly operates to oscillate the bell crank 36 to cause the latch 48 to move the lever 52 into position to actuate the engages a cam roll 56 provided on the end of the arm 42 of the bell. crank 36 and causes a further power oscillation of the bell cranlr and thereby a final operation or movement of the jack downivardly. The completion of the cycle of rotation of the cam 22 serves to release the trip latch 48 and allows the lever 52 to restore the clutch to an inoperative position. For purposes hereinafter to be men" tioned, the cam 22 is designed to effect a pe riodic depress-ion of the jack in timed rela tion to other operative portions of the machine. In order to facilitate the presentation and removal of the shoe from the machine, the jack posts are pi'eferi'tbly swung back out of the operators way in their normal position, Fig. 1, and they are swung into operative relation to the shoe upon the ini tial depression of the foot treadle by an arm 59 which is fast on the shaft 1.0 and carries at its upper end a cam roll 60 which is re ceived in a cam groove 61 provided in the head of the frame, the cam groove being ar ranged to swing the jack posts forwardly into a substantially perpendicular position on the shoe bottom.

In the illustrated en'ibodin'unrt of the in vention the shoe lasting device consists of an approximately shoe shaped pouch or form 62 adapted to receive an unlasted shoe in an inverted position. Preferably, this shoe-- shaped pouch or form consists of a yielding and resilient material such as vulcanized rubber having suilicient elasticity to enable it to be extended or stretched while in con tact with the shoe whereby a frictional. drag may be produced upon, the unlastcd shoe upper which will act to tension the upper about the last. The rubber shoe-shaped form or matrix 62, as it may conveniently be termed, is preferably so shaped and arranged as normally to present a shoe receiving space corresponding to the shape of a shoe of medium sir-5e, that is, a size of shoe between the range of sizes for which the form is adapted and of a depth to enable the upper margin of sides of the form readily to be carried 0 on to the shoe bot-- tom during the operation of the n'iaelnne.

Although the matrix 62 is not herein shown as being reinforced, it has been found desirable under certain conditions to provide a fabric backing for portions of the matrix as, for example, where the matrix engages the more or less angular contour of the cone of the last. Also, such matrix may be so made as to provide for its extension or elasticity along a con'iparatively narrow portion adjacent to the marginal side faces of the shoe. This matrix 62 is ren'iovably sup-- ported in the machine at substantially the center of the toev and the heel and on either side of the matrix at the tip line, the ball line and the heel breast; line by clamp members 64;, 65, (3G and til respectively. Each of the clamps comprises two plates which are formed 011 their forward ends to receive an enlarged clamping edge provided on the matrix 62 and are secured together by screws (38, the under side of the forward end of the lower plates of each of the clamps being formed to present a downwardly projecting surface 69 130 assist the matrix in pressing the margin of the shoe upper in adhesion to the upper surface of the innersole. The heel and toe end clamps 64 are each pivotally secured on the studs 70 to the upper ends of their actuating arms 71 while the side clamps 65, 66 and 67 have a ball and socket connection 72 with their actuating levers 73, 7 1 and 75 respectively to provide for lateral play of the clamps and also free movement of the clamps upwardly from a horizontal position.

The matrix actuating levers 71 located at either end of the matrix are pivotally mounted on studs 76 carried by main actuating levers 78 which are mounted for oscillation lengthwise of the matrix (32 on transversely disposed shafts 80 having hearings in the machine frame. Both of these levers 78 have short arms 82 projecting toward each other each of which is provided with a segment gear 84. The matrix actuating levers 7 1 which support the matrix 62 at substantially the ball line are fulcrumed upon shafts 86 journaled in hearings on opposite sides of the machine and extending longitudinally of the matrix 62, the shafts 86 being located in substantially the same horizontal plane as the shafts 80 upon which the levers 78 are pivoted.

The side levers 74 are provided with enlarged portions projecting toward the other from their hubs 88 and the forward face of one enlarged portion is formed as a spur gear 90 which meshes with a. similar gear provided on the forward face of the hub 88 of the opposite rear side lever 74. Also, a curved segment gear 92 is provided on either side of the spur gear 90 on the hub 88 of one of the levers 74, these segment gears 02 being disposed so as to mesh with the segment gears 84-. on the levers 78. The front side lever 74: is provided with an arm 93 depending from its hub 88 and carrying a cam roll 94 at its outer end which is received in a cam. groove 95 formed in a cam 96 on the driving shaft 24. By reason of the described construction and arrangement of the end and the side actuating levers for the matrix they are all actuated in unison from the single operating cam 96, thus providing for a uniform and symmetrical lasting action of the matrix on the shoes.

The side levers 73 and 75, which act upon opposite sides of the matrix at the tip line and the heel breast line respectively, are pivotally mounted on studs 97between the forks of forked operating

arms

98 and 100, respectively, the upper ends 101, 102, respectively, of each of the forks extending longitudinally of the matrix to provide for longitudinal adjustment of the

levers

73 and 75 as will hereinafter be de scribed. The forked levers 98 and 100 are rigidly secured to the shafts 86 at their respective ends and each set, 73 and 75 respectively, is provided with

arms

103, 101 which project toward each other from the hubs of the levers (Fig. 1) and have intermeshing teeth formed on their forward ends. The rear outside lever 100 is provided with an arm 106 carrying a cam roll 107 which is received in a cam groove 108 formed in the side of the cam 96. Thus the side levers 73 and 75 are also actuated in unison from the cam 96 and in timed relation to the actuation of the

levers

71 and 74.

The illustrated machine has provisions for effecting an initial adjustment of the normal shape or shoe receiving space of the matrix 62 corresponding to any change in the size or style of the shoe to be operateijl upon and incidentally to vary the amount of converging movement imparted to the. matrix by the matrix actuating levers 71, 73 and 75, such adjustment preferal'ily be ing adapted to effect an equable and symmetrical adjustment of the matrix. As illustrated, the adjustment of the matrix 02 to effect an elongation or shortening of the shoe receiving space is obtained by adjust ing each of the end matrix actuating levers 71 longitudinally relatively to the main aetuating arms (8 upon which they are pivotally mounted and to the side levers 74:. This adjustment comprises an adjusting screw 110 which is rotatably secured by the collar 11.1 in the lever 71 and has its for ward end threaded into a pivot block in the upper end of the main actuating lever 78, a hand wheel 114 being provided for manipulation of the screw. Thus, upon rotation of the screw 110 at either end of the matrix 62 it may be given the desired length properly to receive the shoe to be lasted. .-\]so this adjustment of the matrix 62 efli'ecis a corresponding change in the amount of. movement imparted to the matrix by the levers 71., 73, 71 and 7:) in laying the margin of the upper into lasted position on the innersole. In order to effect a symmetrical elongation or shortening of the matrix to produce a shoe receiving space approxi' mately complemental to the shoe to he lasted and thus insure a uniform lasting action off the matrix on all portions of the shoe, the width or transverse shoe receiving space or opening is adjusted and, as shown, this adjustment is effected simultaneously and proportionally to the longitudinal adjustment of the matrix. For this purpose, the

levers

73 and 75 on either side of the machine, which control the operation of the matrix at the tip line and the heel. breast line respectively, are each provided with a laterally projecting arm 11.6 having a ball socket to receive the ball shaped end 118 of a link 120, the other ball shaped end 122 of which is received in a ball sockct formed on a lever 126 pivotally mounted on the outer end of the transversely eX- tending shaft 80. The outer end of each of the levers 126 projects a distance beyond its connection 122, with the link 120 and is connected by a link 128 to the lever 71. Thus, movement of the levers 7i ow- 111g to an adjustment by means of the hand wheel 114; effects a corresponding longitudinal adjusting movement of the

arms

73, 75 in the

guide arms

98, 100 respectively. By reason of this adjustment of the arms 73, being through the

links

120, 128 and connection 126 to the levers 71, an adjustment proportionate to the adjustment of the levers 71 is obtained so that the transverse contour of the matrix 62 is changed in common with the cl'iange in the longitudinal conformation of. the matrix according to the size of the shoe to be operated upon. While the described adjustment of the ma trix 62 by the manipulation of the hand wheel 114 at both of its ends is usually required so as to enable a uniform action of the matrix on the shoe, it has been found in practice that in lasting shoes in which the box toe or the heel stiffener materials are unusually heavy, or in case that a greater application of tension is desired at one end of the shoe than the other, an independent adjustment of the matrix at such end may be conveniently made, the side levers 74 serving to prevent endwise movement of the shoe in the matrix.

In the operation of the machine herein described, the unlastcd shoe is placed in an inverted position in the lasting device or matrix 62 as indicated in dotted lines in Fig. 2. The matrix presents a continuous upper engaging surface completely around the shoe and of a contour approximately complen'iental to the sides of the shoe. The foottreadle (not shown) is then depressed which acts to raise the treadle rod 18 and oscillate the lever 12 about its fulcrum 14;.

. As the forward end of the lever 12 is moved downwardly toward the shoe bottom, the

'arm 59, the upper end of which is controlled by the cam slot 61, operates first to swing the toe and heel posts 4 and 6 respectively into iierpondicular position, the fingers l6 and the end of each of the posts 4-, 6 engaging the innersole and providing a pluralit of points of support at both the forepart and the heel of the shoe against any tendency of the shoe to be displaced as it is forced downwardly. Nhen the posts l, 6 move down, the ends of the spring fingers first contact with the surface of the inner sole (compare Figs. 1 and 5) and as the ends of the posts approach. the innersole, said fingers spread and exert an outward pushing action on the innersole and finally bear thereon so near its margin as to hold the latter snugly to the last. The downward movement of the jack posts acts to depress the unlasted shoe into the matrix 62. The depression of the foot treadle oscillates the bell crank lever 36 about its pivot 38, and after the initial manual depression of the shoe into the matrix has been effected, the arm lei is moved outwardly or to the left, Fig. 1, a sufficient distance to cause the latch 48 carried thereby to engage the boss 50 provided on the clutch operating arm 52 and move the said arm into position for the clutch pins 5s to op crate, whereby the main driving shaft 24; is rotated through the bevel gear connection 32, 4:0 to the driven shaft 26 carrying powcroperated movement of the posts in the direction to force the shoe into the matrix. The matrix is thus forced into exact conformation with the side faces of the shoe and since it is supported along its upper edge, the relative movement of the shoe causes the inner or upper engaging surfaces of the n'iatrix to wipe the upper upwardly in the direction of the shoe bottom, thus tensioning the upper about the last. Also by reason of the extensibility or elasticity of the material constituting the matrix 62, the movement of the shoe serves to stretch and extend the matrix while it is in conformation with the shoe, thereby producing a frictional drag which action is particularly effective in eliminating any wrinkles in the upper and conforming the upper to the shape of the last. It will be seen that as the shoe is further depressed into the matrix, the ac tion of the matrix upon the shoe becomes correspondingly greater, and since the normal shape or form of the matrix is main tained by its supporting and actuating

arms

71, 73, 74L and 75, substantially all portions of the shoe upper are treated alike, whereby a uniform application of tension is secured and the shoe upper accurately conformed to the conforn'iation of the last. The shoe is preferably depressed into the matrix 62 a distance sufficient for a margin at the sides of the matrix to project above the bottom of the shoe after sufficient tension has been applied to the upper, this position of the shoe being indicated by the dot and dash upon the shoe upper, 5

lines, Fig. 2'. After the shoe upper has been suliiciently tensioned about the last, the enis so timed with relation to the relative tension applying movement of the shoe that it occurs in continuation with the depression of the shoe into the matrix that is, during the latter part of the depression of the shoe. The operation of the matrix actuating levers 71 and 74, as above described, is efi'ected from the cam 96 on the main driving shaft 24. This cam oscillates the for ward side lever 74- about its fulcrum on the shaft 86 whereby the laterally projecting arm 82 is moved in a direction to cause the end levers 78, through their inter-gearin 84, 92, to be oscillated about their fu crums on the shaft 80, and the levers 71, together with the levers 74, caused to be moved inwardly over on to the shoe bottom and thereby carry the sides of the matrix into position to lay the margin of the upper into adhesion to the upper surface of the insole. The cam 96 also acts upon the arm 106 of the front lever 100 at the rear end of the matrix to oscillate it and the arm 75 pivoted thereon, and causes a similar oscillation of the

levers

75, 100 at the opposite side of the matrix. Also, a corresponding lateral oscillation of the

lovers

78, 98 on either side of the front end of the matrix is effected by the oscillation of the shafts 86 to which they are rigidly securc'd. The converging movement imparted to the margin of the matrix by tie actuation of the levers 71, 7 3, 74 and 75 produces a uniform and symmetrical action on the shoe, and by moving the shoe downwardly into the matrix simultaneously with 'such converging movement of the margin of the matrix over on to the shoe bottom, the upper remains under an active tensioning force during the operation of the matrix to lay the margin of the upper over on to the innersole, thus eliminating any possibility of the tensioned upper reacting during the change of direction of the operating forces, first in wiping the upper up the sides of the last and over on to the innersole. This organization of operating mechanism enables the margin of shoe upper to be laid over on to the innersole progressively from the outer edge of the shoe inwardly. This feature is of considerable importance in pro viding a satisfactory machine for lasting shoes in which the lasted upper is tempo- .rarily secured to the innersole by cement inasmuch as substantially no manipulation of the upper is possible after it has once. been brought in contact with the innersole. Immediately after the margin or sides of the matrix 62 have been carried over on to the shoe bottom so as to enwrap the sides of the shoe and the margin of the bottom surface of the shoe under the tension of the matrix, as indicated in Fig. (i, the toe and heel posts 4 and. 6 are given a slight upward movement by their ()lXl'tltlTlfl cam sufficient to permit the shoe to be moved upwardly. This upward movement of the shoe serves to press the projecting surface (15) on the under surface of the clamp members 64, (i5, 66 and 67 upon the overlasted margin of the inncrsolc and into proper :ulhcsion thereon. A final depression of the toe and heel posts is then effected by the cam 22 which enables the portion of the matrix overlying the shoe bottom and the sides of the matrix to free itself from the shoe without disturbing the lasted position of the shoe upper on the last during the return of the matrix to its normal shoe receiving shape by its actuating levers 71, 73, 74 and 75. In case the shoe to be lasted is of a substantially different size or style than the shoe previously lasted, the normal shoe re ceiving shape or conformation of the matrix 62 may be varied by manipulation of the hand wheel 114 which effects a corres mmh ing elongation or shortening of the matrix and simultaneously therewith :1. corresponding longitudinal adjustment; of the

arms

73, 75 between the forked arms of the lovers 9S, 1G0 respectively. Thus the pouch or matrix may at all times present a eontinlujms surface which is substantially con'iplemental to the shape of the shoe to bc lasted. If the shoe to be lasted has an excess or unusual amount of box too or heel stiffener materials, in which event the normal uniform operation of the matrix will not be sullicient properly to conform the materials to the desired conformation of the last, an independent adjustment of either end of the matrix 62 may bev made whereby a more effective action of the matrix on. the shoe is produced. In this case, the side levers 74 are given the usual amount of lateral oscillation to conform the upper materials to the last so that they also serve the. additional function of clamping the shoe against any endwisc movement in the matrix. This adjustment of only one end of the matrix has also been found useful in drafting a shoe upper about a last in which the shoe upper has been cut scant. By adjusting the toe post 4 and heel post 6, the amount of depression of the shoe into the matrix may be controlled, this adjustment also co-operating with an adjustment of the matrix to allow the shoe to be placed to a greater depth in the matrix for the purpose of controlling the ammint of tension applied to lilt) the shoe upper. If desired, the cam 96 controlling the operation of the matrix actuating levers 71, 71', 74 and 75 may be so formed as to cause a slight initial opening of the shoe receiving space in the matrix 62 after the shoe has been positioned therein, thus insuring that all portions of the shoe shall be acted upon.

It will be noted that in the use of the above machine, ashoe may be satisfactorily lasted in a single operation quickly and economically. Also the use of this machine does not necessitate the entiployment of a skilled operator, which, in the manufacture of footwear of this type is of considerable importance inasmuch as such shoes are comparatively inexpensive and, therefore, it is essential that in providing a power operated machine the cost of the lasting operation be reduced to a minimmn.

Important features of the invention which enable rapid work to be done satisfactorily by an unskilled operator consist in theconstruction and arrangement: of the member 652 hereinbefore referred to as a pouch or matrix, which is formed to completely surround a shoe upper on a last. It will be noted that the member 62 performs all the functions of lasting the upper. Moreover, it efl'ects co1nplete lasting by a single operation. It is, practically, a pouch which serves several purposes. First, its normal shape and size are such that the space within it will receive an assembled last and. upper and support the same; next, when the posts 1, 6 depress the last, the upper is completely tensioned about the last; and finally its complete or continuous marginal portion which is con'i n'essible effects the securing of the n'iargin of the tow sioned upper upon the innersolc as hereinbefore described.

It will be noted that the illustrated lasting element 62 furnishes, when in normal or idle condition, a support which will enable the operator to properly locate an upper and last therein, or in other words, means for guiding the last and upper to proper position for lasting; means for tensioning the upper about the last when relative movement of the last and lasting means is effected in the direction of the height of the shoe; and means for uniformly overlaying the entire margin of the tensioned upper upon the shoe bottom in lasted position without requiring the operation of some other element to co1nplete the lastin Particuh advantages obtained by means of the member 62 are that the operator can readily see what he is doing when he puts the assembled last and upper and innersole in the pouch which holds said parts preliminarily without any other support such as a jack. Since the last and the shoe parts rest in the member62 in an inverted position, the operator can readily gage the place of the shoe parts so that the amount of overlap of the margin of the upper can be accurately gaged.

An important factor in obtaining the aboveanentioned advantages is the mounting and operation. of the aclr so that its posts 4-, 6, normally occupy a position separated from the lasting device 62 far enough, and also so laterally displaced as indicated in Figs. 1 and 2, as to enable the operator to manually manipulate the shoe parts on a last while the latter is supported by the lasting device, after which the jack is shifted to position above the work-supporting lasting device and the lasting operation is effected as here inbefore described and as illustrated by com paring Figs. 3, 5 and 6. Upon completion of the lasting operation upon one shoe, the jack automatically returns to the normal displaced position indicated in Figs. 1 and 52 so that after removal of the lasted shoe an other last with shoe parts thereon can be located as indicated in Fig. i, with nothing in. the way to interfere with the operator see ing the work and effecting any manipulation that may be desirable.
