Original application filed October 5, 1910, Serial No. 585.432.

Specification of Letters Patent.

1911. Serial No. 655,912.

' To all 1li/mm if muy concern -Be it known thatl. MA'rrmAs Bnocn, a citizen ofthe [lnited States` residing at llos4 ton, in the county' of Suffolk and State of Massachusetts, have invented certain Improvements in End-Lasting Mechanism for felt-Shoes, of which the following 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 novel 'apparatus for use in making shoes and it has for its at the frontl portions object to provide lasting mechanism by which to improve the fitting of a. welt shoe of the heel vand th rear of the shank, this mechanism being one formof apparatus by which to practise the method claimed in my prior application Serial No. 585.432 filed October 5, 1910, of which application this present case is a division. A usual practice is to last this por-v tion of the shoe by means of shear-like wipers having shaped edges to embrace the heel portion of the shoe and be closed over .the heel bottom to'rub t-he upper inwardly upon the bottom face of the shoe to position to be secured to the innersole. It is found that with the lasts now in use, in which the last bottom is comparatively narrow at the breast of the heel and at the shank. insulticient upper tightening force is applied by the wipers at the port-ions of the shoe acted upon by their ends. In accordance with this invention additional upper tightening force is obtained without the employment of any supplementary mechanism,

an abutment or backing against z This apparatus is particularly useful in lasting shoes in which is-used a known type of heel stiffener which has an upstanding lip on each wing provided to stand against the outer face of the innersole lip. In accoi-dance with the method above mentioned I shape this lipped stiffener so that its lips stand in the assembled shoe more or less away from the innersole ribs and serve-as which the upper is gripped by an edge face of the wipers. By so gripping the upper between the two opposed aces each of which can -move in the direction ofthe force applied, the upper is pulled as distinguished from being wiped or rubbed inwardly i l l l l l l last edge to tighten it. The upper gripping edges of the lasting plates are preferably serrated or provided with pointed projections the better to engage theI upper with a grip against the stitl'ener lip while the latter serves as an abutment or cooperating gripping member. Preferably the lasting plates are formed and arranged at their front. ends to bend the upper at the front of the heel or the rear of the shank over the top edge of the stiiiener lip and grip it upon said edge as well as gripping it against the outer side of this lip. A stiii'ener is always made of hard slightly resilient material and is usually compressed in its manufacture. The upstanding edge is commonly skived to render it thin before the stitfener is molded so that it presentsa narrow, sharp edge by which the upper bent over it is held to a substantial extent. -By bending the upperA over this edge. then downwardly agaiustthc side face of the lip --and outwardly over the flange ol' the stiti'ener the upper is held thereto with a friction that insures a strung tightening pull as the stiii'ener non-slipping und upper are forced inwardly Ab v the lasting plate.l l1`or the above stated purpose the lront cud portions ot' the lasting plates may l with an inwardly directed ledge or o\m"h.|ueiug lin spaced above its lower tace a distance about equal to the height of the still'ener lip and adapted to bend the upper o\er and grip it down upon the top edge ol' said lip as the serrated face approaches and grips the upper against the outer t'acc of said lip.

While the features ot' the apparatus are of part icular utility for lasting in the above described manner a shoe that includes a lipped heel stiil'ener. the invention in its broader aspect contemplates other advantageous uses of the apparatus in the lasting ofwelt shoes without, reference to the particular type of stiti'ene employed. as will be pointed out in the following detailed description.

The invention will now be explained in connection with the accompanying drawings, which illustrate the preferred construction at the time this inventioni's made, and the several features ofthe invention will be pointed out in the claims.

Figure 1 is a 1an viewof a heellasting be providcl from` the machine embodymg this invention; Fig. 2 is from a hand stock standing along the The offset 15 and the wall 16, provide' for edge of the shoe a perspective sectional view; Fig. 3` is a similar view in which an upper holding clamp is used; Fig,4 is a perspective view from below of the novel lasting plate of Figs. 1 and 2.

he heel lasting mechanism comprises a head 30 which supports the sliding and turning lasting plates 14 and their carriers having the cam slots 3Q, 38 in which stand roller studs rising from the head and directing the movement of the wipers which is transmitted to them by the links 35 and rod 36 lever or other source of power as usual, the shoe having first been embraced and clamped by the heel band 38. These parts constitute no portion of this inven tion but may be the same as in prior United States Letters Patent No. 1,018,477 granted on my application Feb. 27, 1912.

The front end of each lasting plate 14 is formed as'shown in Figs. 2 and 4 by having its inner edge offset as at 15 near the location of the breast line of the heel and the continuation of said edge extends in a plane raised above that of the body portion a distance about equal to the usual height of an innersole rib 10. Back of this raised edge and covered by the portion 20 of the plate is ali-outwardly offset portion of said acting edge which may be designated as a wall or abutment 16 formed substantially straight and adapted to abut, when the lasting plates are in final position as in Fig. 2, against the side of the rib 10.

last in the usualmanner. The stiener preferably has the flange 6 which at the forward portion of each wing is narrowed by turning up a lip 8. The flange is skived to present a sharp edge on the upstanding lip 8 and the stitfener which is formed of hard sole leather, or some material having simi lar characteristics, has been molded tothe illustrated shape which is substantially permanent and to a condition of hardness and resiliency adapting it to serve its purpose as is well understood. shaped, for the best results, so that the lips 8 will stand laterally away from the rib 10 of the innersole in t-he assembled shoe as in Fig. 3. The heel embracing wipers 14 are advanced and closed to force the upper and the stidener flange inwardly upon the innersole to position to be fastened, the offset 15 coming near the location of the breastline of the heel, and the continuation thereof at 16 extends along the side of the shoe toward the end of the stitfener wing. rEhe pointed projections 18 are overhung by the ledge or n 20 the lower face of which is spaced above ythe lower face of the lasting plate a distance substantially equal to or slight-ly less than the height of the lip 8 .on the stiffener. In the advance of the lasting plates by the rod 36't-he ledge 20 bends the upper over and clamps it down upon the sharp top edge of the side of said lip backing for the upper while the advancing wiping the upper inwardly less far over the margin of the innersole by the ends of the lasting plates tha-n by the body portions of said plates. By this construction the plates are adapted to the formation of a welt shoe. The heel seat vof a welt innersole is not channeled and it is desirable to wipe the vupper in and lay it down hard on the heel seat for a considerable distance from the for the lasting tacks uust be driven inside the line in which the heel attaching nails are driven. In front of the breast ofthe heel seat the innersole is channeledand provided with the inseam connecting rib which is located about of an inch from the edge of the shoe. Formerly wipers have beenl driven over this rib in order to close them over the heel seat far enough and this has crushed the rib and increased the ldifficulty which has been much commented upon in sewing a tight inseam at this point. The wall 16 may or may not be furnished with impaling pins 18 'and' :when so furnishedthe lins are conveniently mounted on a removab e plate 19 asin Fig. 4,r and spaced a'substantial distance above the lower face of the plate 14.

' ln the use Iof this invention for lasting welt shoes the inners'ole the upper 4 and employed, grips the upper against lthe outer over the projections 18 and acts as a shield to protect the upper from contact with-the projections during the first portion of the the plate continues its closing movement it springs the wings of the stiffener inwardly, and said lips and the edges 16 coperate to pull the upper inwardly in addition to and as distinguished from the mere wiping or rub bing action of the wiper over the stock. In the hugs the heel of the wearers foot better and has less tendency to slip up and down, especially inv oxfords andv pumps, because of this formation of the heel stitfener for it will be noted that the end portions of -the lasting plates114 have'a substantialcomtoe of the iastas they close over the shoe bottom and that, .inasiuch as the faces 16 with their projections 18-gripthe upperin a manner to restrain slipping,the upper" at the sides of the heel and shank will be pulled forwardly as well as inwardly. lt is important to emphasize the essential distinction between the pulling action effected wall 16, with its projections 18 if they are' ponent of forward movement. toward 'the the heel stiffener are assembled upon the l yao lip 8, Fig. 2, and the 8 forms an abutment orface of said lip. The fin 20 forms a cover inward movement of the lasting plate. A s

iio

finished work the heel portion of the shoe by gripping the upper against the lip 8 and forcing the upper and the lip inwardly toget her and the well known wiping action effected when the ordinary wiper rubs frictionally over the upper. It is because the latter action is insufficient that thel former is provided in accordance with this invention. For further assisting the lasting plate to tighten the upper over the last at the end of the heel sti'ener the plate Amay have the clamp 25, Fig. 3. This clamp is pivoted to the plate and acted upon by a bow spring 26 to force it down upon the upper witha sufficient gripping force. The connection between the spring and the clamp is `above the pivot of the clamp when the clamp is down and below the pivot when the clamp is up so that the spring holds the clamp in its upraised position as well as in its 'down turned position. The clamphas a handle 28 by which to operate it and this handle ils. arranged to afford means by which the (ip-- erator may apply additional force with his hand .to grip -the upper more securely on ene side of the shoe or the'other in a special case requiring particular attention. r
