LASTING- APPARATUS.

Application filed September 14, 1912, Serial No. 720,380. Renewed May 6, 1918.

To all whom may concern Be it known that I, ELI BROTHERS, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in Lasting Apparatus, of which the following description, in connection with the accompanying rawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the manufacture of boots and shoes and among its objects are to facilitate the shaping of an upper to its last and the permanent fastening of the upper to the innersole or the sole, and to protect the upper from injury or soiling during the shoe making operations.

Any important feature of the invention consists in novel apparatus for use in working an upper into lasted position on a last. The construction herein shown as an illustrative embodiment of the invention comprises a device constructed to extend about substantially the entire periphery of a shoe in conforming relation to the contour of the lateral surface of the shoe lengthwise of the bottom edge about the forepart and while abutting against the shoe at the rear of the heel portion to be forced in a direction to wipe the upper at the forepart over the lateral surface of the last toward the bottom edge of the shoe. By use of the device in this manner the upper lis wiped into lasted position with the margin of the upper upstanding substantially at right angles to thel plane of the'sole of the shoe. Preferably the device is made of resilient material to cause it to conform to slight irregularities in the shapes of dierent shoes while presenting` normally a contour characteristic of the shoes of a given size and style. rlhe device herein shown is also shaped to conform substantially to the vertical contour of the shoe about the forepart for a considerable dis` Serial No. 232,979.

clamping. the updrawn upper about the periphery of the forepart of the shoe tothe lateral surface of the last and the edge face n upper to the sole. An advantageous characteristic of the illustrative construction, as adapted for use upon some types of shoes such as turn shoes, is that while holding the upper securely in 'place it leaves a portion of the upper located opposite to the edge of the sole free to be operated upon inthe upper and sole securing operation. y Preferably, moreover, the device presents an uninterrupted exterior face substantially parallel to the lateral contour of the last adjacent to the shoe bottom adapted to serve as a guide during the presentation of the shoe to a machiney for securing the upper to the sole. lNhile this feature of the invention is herein shown as embodied in upper holding means yadapted for use initially to work the upper into lasted position in the manner hereinbefore explained, in its broader yaspects the invention contemplates the provision of novel means for holding an upper in lasted position irrespective of the particular manner in which ,the upperv may have been tensioned and conformed to the last.

Still another feature of the invention consists in the combination with a last of a shoe embracing member adapted to fit snugly the lateral surface of the shoe while leaving the lower surface exposed, such member serv ing to protect the upper of the shoe from injury or from being soiled 'during subsequent manufacturing operations.

By the use of the illustrated embodiment of this invention important advantages are obtained among which may be mentioned economy of time and labor and upper stock as well as the saving of toe fastening material, together with a superior quality of toe j lasting because'good qualities of the wiper ytype of bed lasting are secured without the slacking back of the stock whichis incident to the withdrawal of machine lasting plates after the application of the temporary fastening means in order to permit the shoe to be presented to the welter.

Other features of the invention, several of 'which are important and which include certain details of construction and combinations of parts, will appear from the following description of a pi'eferred construction and will then be pointed out in the claims. The improvement in methods of making shoes which is herein disclosed is claimed in a divisional application Serial No. 100,366, tiled on May 27, 1916, upon which Letters Patent No. 1,482,220 were granted on J anuary 29, 1924.

Fig. 1 is a side view of apparatus in which the invention is embodied:

Fig. 2 is a perspective view of the apparatus shown in Fig. 1;

Figs. 3 and 4 show modifications.

Fig. 5 shows a section through a shoe lasted by this apparatus and held in lasted condition thereby while being sewed, the shoe in this instance being a turn slice, and this figure also illustrating how a welt may be secured to the upper and insole of a lasted shoe in the case of a welt shoe.

The apparatus shown in the drawings consists primarily of a toe or a forepart em-Y bracing member 2 in the form of a shell which may advantageously be made of spring metal and which is shown as of thin spring metal shaped substantially to the contour of the edge portion of the last with which it is to co-operate, being a snug fit thereto so that as it is forced upwardly on the shoe about the inverted last, Fig. 1, it will wipe the upper stock into lasted position and there maintain it. The member 2 is preferably so formed on its inner side that it is concave in vertical cross section and inclined rearwardly at the toe end, said face being shaped to conform substantially to the vertical contour of the toe end of the last. This has two advantages. The shaping action is extended downwardly from the edge of the inverted last when said member is in place so that the upper is clamped to the side face of the last for a substantial distance from the last edge downwardly. Also this shape assists the operator in positioning` the end embracing Amember at the right elevation relatively to the plane of the last bottom to hold the upper most effectively and to facilitate subsequent operations on the shoe embraced by said member.

The embracing member 2 is to be attached to the shoe for maintaining the upper stock in lasted position while the shoe ishandled, as for the purpose illustrated in Fig. 5

y Vhile variors constructions may be employed for attaining this result, I prefer to extend the sides of the member 2 rearwardly as at 3 to, and it may be around, the heel end of the shoe. In Figs. 1 and 2 the ends 3 are connected yieldingly and adiustably by a bolt 4 and springs 5, 5 while in Fig. '3 they are connected yieldingly by a bow spring 6 and in FigA 4 they are connected adjustably by a stud and eccentric latch 7..

These constructions all have the advantage that no projection above the shoebottom is presented which would interfere with the opera-tion thereon of such machines as the sewing machine of Fig. 5. The rear end portions 3 are cut away at their bottom edges 8, or are defiected downwards to allow a heel seat lasting and tacking machine to operate upon the side as well as the bottom of that portion of the shoe which includes the heel stiffener.

rlie embracing member 2 preferably includes portions shaped to lay the upper stock at the shank into the shank curvature of the last in position for sewing as at 9 and these shank formers or wipers 9 may or may not be hinged to the member 2 as at 10, Fig. 3.

The embracing member may be applied by hand, as by passing' it over the shoe in such manner as to encounter the least resistance and locating its heel end portion in approximately final position in abutting relation to the heel end face of the shoe and then swinging the forward portion upwardly with the lingers while the thumbs rest upon the shoe bottom, whereby the entire forepart and shank of the upper is wiped up at once to the position shown in Fig. 1 and is secured in lasted position as there shown. The upper at and about the toe may be doubled down over the top edge of member 2 while said member is being forced upwardly whereby desired tensioning` of the upper may be obtained at whatever places it is needed.

In Figs. 1 and 2 is shown means for effecting the toe lasting movement of the embracing member 2, said means comprising a toggle the upper arm 12 of which is forked to have detachable engagement with lugs 13 on members 2. The lower toggle arm 14 is pivoted to a fixed support such as the rod 15 that is held by binding screw 16 in a last pin 17 with capacity for adjustment to use with shoes and embracing members of different lengths. The toggle has an operating member 18 which is rigid with upper arm 12 and which has a face 19 to engage an abutment on arm 14 by which the toggle is locked when it has been operated to straightened position. These arrangements, taken with the adjustment of the rod 15, provide for raising the embracing member 2 to an approximately uniform vertical relation to the shoe bottom, it being preferable that it should occupy substantially the operative position disclosed in Figs. 1 and 5, in which it partially overlaps the edge face of the sole and maintains the upper in lasted position against said edge face with the margin of the upper standing substantially at right angles to the plane of the sole.

The parts above described constitute with the embracing member 2 a lasting machine of which the lasting means 2 is adapted,

while kholding upper stock in lasted relation to the last, to be removed with the shoe so as to maintain the upper in lasted condition while the shoe is being presented to anot-her machine, as for example the fastening machineindicated in Fig. 5. The device is effectively retained in position for holding the upper about the forepart through the action of the heel embracing portion assisted by the rearwardly curved toe portion and the inwardly curved shank portions of the device.

In Fig. 4 the embracing member 2 yhas a portion 2() to press the upper into the ylow place usually found on the top face of the last between the toe and the instep. ln this figure also the member 2 is formed in two sections connected by hinges 2l. llVhen the latch 7 has been unfastened the sections of member 2 can be turned to open said member for removal from a shoe after the upper has been fastened, Fig. 5, with-out wiping the upper down from the edge of the last.

lt is contemplated that use will be made of the illustrated apparatus by applying an upper to a last and then applying the vembracing member 2, positioning its heel portion substantially as shown .and forcing the forward Vportion upwardly in rubbing contact with the stock to wipe lthe upper to lasted position, Fig. l., after which .the shoe with the embracing member v2 clamping the stock in lasted position will be removed to a convenient place and subjected to a suitable upper and sole connecting operation, for eX- a-mple as in Fig. V5, r lif it be a McKay shoe the upper margin will be laid inwardly over and tacked to the innersole.

lt will be evident by .reference to the drawings that the member 2 cpresents an vuninterrupted exterior surfaceA which is substantially parallel to the lateral contour of the last lengthwise of the bottomedge of the shoe, this surface .beingadapted -to serve advantageously as a guide in the presentation of the work to a `machine for securing the upper to .the sole. rlhis smooth surface is entirely free from such irregularities as are presented on the lateral surfaceofa shoe, as, for example, at the ,rear edge of the .toe tip, and by the use of the device the operation of securing the upper to the sole fis consequently facilitated.

It will be apparent furthermore .that :by the use of this invention the usual time consuming operation of temporarily fastening the upper in lasted 4position by the use .of

fasteners inserted in the shoe is entirely eliminated whereby labor is saved; that .the slacking back of the stock which results to a greater or less kdegree :upon withdrawal of the lasting means after application of temporary fastenings .is avoided so that tighter lasting `and permanent fastening are obtained and the .appearance of the shoe thereby improved; and that the upper pattern rmay be cut substantially smaller because it is only needful that it -be long enough to permit the permanent fastening as in Fig. or otherwise.

lt should be understood that the term sole is used herein in its generic sense and except where required by the context imports no limitation as to the specific character of the bottom portion of the shoe to which the upper is to ibe secured to hold it in lasted position, whether the shoe be a welt shoe or a turn shoe or a shoe of other type.
