T 0 all whom it may concern:

Be it known that I, LOUIS M. BROWN, a citizen of the United States, residing. .at- Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in' Lasting-Machines, of which the following description, in connection with the accompanying drawings, isa specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines, being herein shown as embodied in the end lasting mechanism of a machine of the bed type and its object is to improve wiper mechanisms of the kind'used in such machines.

A particular object; of the invention is to obtain a more effective bearing of the wiper upon the marginal portion of the shoe bottom for forming the upper upon the feather of the innersole and into the angle between the feather and the lip or shoulder It is very desirable that the upper be laid flatly down upon the feather from its edge to the shoulder to form a proper seat for the welt and it is also important that the upper be firmly pressed down into the angle, instead of bridging over the angle as it tends to do. One reason for this is found in the need for providing a seat or bearing for the binding wire with which it is customary to secure the upper in lasted position about the toe and another reason is found in the need for forming the upper down, against theba'se of the lip or shoulder of the innersole so that it can be sewed closeto said base and form a tight seam which is low enough down to allow the surplus upper stock at the inseam to be trimmed close to the face of the sole and require a minimum of filling material in the middle of the sole.

I With the above-mentioned'and other obj ects in view a feature of thisinvention consists in forming the end lasting wipers and their holders relatively to cause the wipers to have a local or heavy bearing uponthe upper at the inner edge of that marginal portion of the shoebottom which they overlie. This result may be obtained in numerous ways of which several are herein explained.

One novel construction embodying this invention includes wiper holders provided with wiper seats that are inclined so as to pitch the wipers downwardly toward the plane of the shoe bottomand in the general direction of their advance movement. Herein the wipers, which advance and close toward each other in the well known manner, are pitched toward each other by the formation of their seats in the wiper holders. Of course the wipers. might have their bodies, or the portions which are received in the seats of the holders, so formed as to give pitch to the upper engaging portions of the w pers.

One important advantage for this embodiment of the .invention appears in the use of reversible wipers. Such wipers are mounted one side upward in their holders for a right shoe and the opposite side upward for a left shoe. It is customary to form wipers with a bevel to produce a thin edge. Reversible wipers of course have to be beveled on both sides. A difficulty which has been experienced heretofore has been that the bevels gave to the undersides of reversible wipers an undesirable upward pitch which caused them to bear with greatest force upon the outer edge instead of upon the inner edge of the marginal portion of the shoe bottom which they overlie. In accordance with this invention the seats in the holders for such reversible wipers are inclined to balance and preferably to overbalance the bevels at the edges of the wipers. By so doing the objectionable upward pitch is overcome and instead there may be obtained the downward pitch which is desirable-for the reasons above stated.

It is of course obvious that the wipers, or the portions thereof which fit into the seats in the holders, may be given the required formation to secure downward pitch of their upper engaging portions, instead of-changing theusual formation of the wiper seats in the holders. A special construction of toe Wipers embodying this invention and affording certain advantages is herein shown as obtained by providing a bead or. rib-on the acting face of the .wiper at'its.

feather and the lip of the innersole and, if desired, to form a seat or crease for the toe binding wire.

Advantage'ously the wiper holder may be undercut to present a lip 14 at the. lower edge of the wiper seat and the wiper will be formed to be supported by said lip, as for example, wit-h a counterpart groove or depression 16 in its back edge to receive said lip.- By the use of this formation of holder and wiper the wiper can be held in place by a single clamp with greater firmness than when the holder and wiper have simply squared abutting faces.

These and other features of this invention, including certain details of construction and combinations of parts, will be now particularly described and others pointed out in the claims.

Figure l is a perspective view of a toe lasting mechanism of a well known commercial form of lasting machine, the two i 1w1per seats in the holders extend oblique I with relation to the median line of the shoe iso that by the inclined walls of the seats Zthe wipers are pitched obliquely downgwardly and inwardly toward the end and respective sides of the last.

wiper plates being separated to disclose their shape in end view. Fig. 2 isa side elevation of a wiper holder, wiper and clamp. Fig. 3 is a plan view showing one modern style of last requiring dissimilar or reversely shaped wipers for the right and left shoe. Figs. 4: and 5 show modifications. Fig. 6 is a detail similar to Fig. 2, but on a slightly larger scale to show clearly the undercut lip at the lower edge of the wiper seat and the cooperating groove in the wiper.

The wiper holders 2 are slidingly mounted in the carriage 4 in which they are fitted between supporting and covering plates to be advanced and simultaneously closed inwardly to move the wipers 5 over the last bottom to the positions indicated in Figs.

2, 3, 4 and 5. This actuation is effected by connections from the wiper holders to the hand lever 6 and by the studs and cam slots shown in Fig. 3. The supporting and cover plates are carried by a lasting head 1 which is vertically movable by a rod connection with a double-ended treadle, not shown, by which the wipers can be raised and depressed independently of or simultaneously with their advance and retraction by the hand lever 6. The wiper holders are cut away on their under sides to form seats to receive the wipers. These seats are formed in accordance with this embodiment of this.

invention with upper walls that are inclined to the plane in which the holders move, which plane, by suitable adjustments familiar to those acquainted with this type of machine, is made to be substantially parallel with the plane of the shoe bottom which is supported by means that includes the usual toe rest 8. This inclination of the upper wall of the wiper seat in the holder will be sufiicient to give to the lower acting face of the wiper a slight pitch downwardly toward the plane of the feather of the innersole and the marginal portion of the shoe bottom upon which it is required to press in molding the shoe upper into lasted position over the feather. By this arrangement the pressure applied downwardly by the edge of the wiper is localized and the wiper is caused to crowd the upper harder down upon the innersole as it rubs over it and to apply local downward pressure adjacent to the angle between the feather and the lip or shoulder of the innersole. In Figs. 1, 2 and 8 a reversible wiper beveled on both sides is shown. In Fig. 4

It is to be noted from Fig. 2 that the The rear end or wall of the wiper seat in the holder is preferably undercut, for example as shown at 10 in Fig. 2, to provide a lip extending under the wiper. to some degree and afforda ing a support which aids the clamp 12 to secure the wiper rigidly in the holder and prevents any loose or tilting movement of the wlper under the wiping and compressing strains to which it is subjected in operatlon. The reversible wiper is formed with a groove or depression as shown in said figure of the drawings to fit said lip when the wiper is in the position shown in said figure or when it is reversed or turned lower side uppermost. Of course it will be understood that in reversing the wipers the plates are not only turned lower side upward but the left hand plate is replaced in the right hand wiper holder as indicated in dotted lines in Fig. 3 to adapt the edge contour presented by the plates to the edge contour of the last which is mate to the one indicated in full lines.

Having explained the nature of this invention described a preferred construction embodying the same, I claim as new and desire to secure by. Letters Patent of the United States 1. In a last-ing machine, shoe supporting means and end lasting mechanism including relatively movable wipers formed to embrace an end of a last, and holders therefor, said wipers and holders being constructed and arranged to present the-shoe engaging portion of the wipers to a shoe on said supporting means so that the wipers will noredge of that marginal portion of the shoe bottom which they overlie.
