Specification of Letters Patent.

LASTING-IVIACHINE.

Patented Feb. 16, 1915.

To all whom it may concern:

Be it known that I, JOSEPH FAUssE, a citizen of the United States, residing at Brockton, in the county of Plymouth and .State of Massachusetts, have invented certain Improvements in Lasting-Machines, 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 lasting machines and particularly to the type of lasting machines commonly called bed laster's' wherein the shoe is supported in operative rela tion to end lasting mechanism for one or for both ends of the shoe. An object of this invention is to improve the shoe supporting means and better adapt it for rigidly holding the shoe.

This invention will be explained in connection with a lasting machine of the type shown in United States Letters Patent No. 521cm in which the shoe supporting means comprises a toe rest and a heel pin and the lasting mechanisms include toe lasting plates mounted for vertical actuation to rub the upper upwardly along the sides of the toe portion of a last into position to be overwi ed upon the shoe bottom.

particular object of the present invention is to render the support for the shoe more rigid in the direction to resist this upward rubbing action of the wipers.

With these objects in view, an important feature of the invention consists in providing a brace or device to engage the lower face of the last in the rear of the heel pin and near the rear end of the last for supporting the last against such upward displacement of its toe portion as would effect a downward movement of its heel end. Preferably this device, which is herein called a brace for the purpose of designation, is formed as a rearwardly extending and, it may be upwardly inclined, horn or arm on the stem of the heel pin, the upper face of said device being advantageously so shaped that its point of engagement with the last is located at a substantial distance away from the heel pin as distinguished from such collars or shoulders as have heretofore been formed on last pins and aflorded a continuous support for the lower face of the last from the heel pin backwardly a limited distance. Preferably the brace will form the sole means for supporting the rear portion of the last against vertical depression so that when the last is applied to the heel pin it will rest down upon the upper end of the brace. In the machine shown, the toe rest is automatically raised a limited distance to uplift the toe of the lastand tip the last backwardly against the heel pin and the brace whereby the last is rigidly clamped by these several last supporting devices.

The heel pin having the brace referred to may advantageously be supported by means which rendersit rigid in the direction to resist backward tipping movement of the last and is herein shown as carried removably in a reversible holder and mounted near one edge of the holder so that when the holder isreversed the pin is adjusted into a different longitudinal relation to the end lasting mechanisms. After such adjustment the pin can be removed from its holder and reversed so as always to present the brace at the rear side of the pin.

The invention will be more particularly explained in connection with the following description of the illustrated embodiment thereof and will then be pointed out in the claims.

Figure 1 is a side elevation partly in section of so much of a lasting machine equipped with the present improvements as is necessary to present for explaining this invention; Fig. 2 is a perspective view of the heel pin and its holder; Fig. 3 shows the novel heel pin removably mounted in and near one edge of a reversible holder.

The machine comprises toe lastlng mechanism A and heel lasting mechanism B in operative relation to which the shoe is sustained by the toe rest C and the heel pin 2. The heel and toe lasting mechanism may correspond in construction and mode of operation with those shown in said prior patent which is embodied in a well known lasting machine. It may be explained that said heel lasting mechanism comprises a heel em bracing band 3 into which the shoe is drawn rearwardly by the engagement of the heel pin with the last. To this end a heel pin holder 4 is mounted in a slide 5, the toothed face of which meshes with a pinion 6 on a shaft which is operated by a hand wheel 8. The shoe is also raised yieldingly by means acting through the pin holder l topresent the bottom face of the shoe in the plane of the wipers, this position being determined by a height gage 9 that projects forwardly over the heel end of the shoe from one of the heel wipers. This vertical movement of the holder is effected by a lever 10 which is pivoted at its rear end to the slide 5 and upholds the holder 4 by its front end. This lever has an inclined face 12 which rests upon a yieldingly sustained screw i l and produces an upward tilting of the front end of the lever as the slide is retracted whereby the shoe is simultaneously forced backwardly into its heel embracing band and uplifted against the gage 9. The toe lasting mechanism includes toe lasting plates 7 of the usual form adapted to embrace the toe end of a shoe and be lifted in rubbing contact with the upper by a treadle connection with the toe lasting head through a rod 11 until they reach the plane of the shoe bottom whereupon they are closed inwardly over the innersole to lay the upper in position to be fastened. The toe rest of the above described machine is automatically lifted through a slide 13 and a cam 15 onv a cam shaft to raise the toe end of the shoe for the purpose of tipping the last backwardly upon the heel pin and obtaining a rigid positioning of the shoe such as will resist the upward wiping action of the lasting plates. This upward movement of the toe end of the last tends to bend the heel pin and to enlarge the pin hole in the last so that as rigid a holding of the shoe as is desired has been difficult to obtain.

In accordance with the illustrated embodiment of the present invention, the heel pin 2 or the stem thereof has formed upon it a strong rearwardly and upwardly projecting arm or horn 20, the tip of which is adapted to engage the lower face of the last at the rear of the heel pin and preferably nearer to the rear end of the last. This arrangement of the part 20 enables it to serve as a brace against downward movement of the heel end of the last which the upward movement of the toe end of the last tends to produce. The upper face of the brace 20 is preferably inclined upwardly so that only the tip or end portion of the brace contacts with the last and this portion of the brace preferably forms the sole vertical support for the rear end of the last. The brace and heel pin form, as will be obvious from Fig. 1, an angular support presenting a two pin bearing with relation to which the last is very rigidly held when the toe rest is uplifted.

The heel pin 2 may be mounted in accordance with this invention and as shown in Fig. 3, nearer to one edge of the holder 4:, as its front edge, than to the opposite edge and the holder is reversibly mounted in the slide 5. This construction permits the the rear of the center of the holder and nearer to the heel band for small lasts. By this provision for adjustment of the heel pin toward and from the heel band a wide range of sizes of shoes including mens, womens and childrens may be supported in proper relation to the heel lasting instrumentalities of this machine by a single equipment, whereas a plurality of heel pins and holders heretofore have been required. Provision is made for vertical adjustment of the heel pin by the screw 18 adjustably carried by the lower portion of the holder 4: and resting upon the lever 10. The heel pin is mounted in the holder by a longitudinal pivot pin 21 that permits lateral tipping of the pin for unsymmetrical lasts, or lasts in which the pin hole is unsymmetrically located so that there is need to equalize the strain as the last is forced backwardly into the band. The pin has oppositely inclined faces on its lower end which are engaged by a yielding centering plunger 19 which maintains the pin in a normal lateral position. The pivot pin 21 is made conveniently removable to permit the heel pin to be reversed in its holder for presenting the brace 20 always at the rear side of the pin.

Having explained the nature of this invention and described a preferred construction embodying the same, I claim as new and desire to secure by Letters Patent of the United States 1-- 1. A lasting machine having, in combina tion with toe lasting mechanism including wipers which are movable upwardly to wipe the upper toward the last bottom and tend to tip the last upwardly and backwardly, shoe supporting means including a heel pin to enter the last and which is rigid in the direction to resist said tipping movement of the last, and a brace to engage the under surface of the last at a point in the rear of tfzhe pin and at a substantial distance thererom.

2. A lasting machine having, in combination with lasting wipers and operating mechanism therefor, said wipers having a tendency to tip the last rearwardly, last holding means including a heel pin to enter the pin hole in the last and a brace to engage the last in the rear of the pin, the point of engagement of the brace with the last being separated by a substantial distance from the pin and means supporting the heel pin rigidly against backward tipping movement by the action of the wipers and permitting lateral tipping movement of the pin to adapt it to the lateral inclination of the last socket.

3. A lasting machine having, in combination with end lasting means and operating mechanism therefor, last holding means including a heel pin to enter the usual pin hole of the last, a rearwardly and upwardly projecting brace on said pin arranged to engage the lower face of the last near the rear end of the last, and a reversible holder in which said pin is removably mounted near one edge whereby the holder may be reversed to position the pin with relation to the end lasting means and said pin can be reversed to continue the brace at the rear of the pin.

4:. A lasting machine having, in combination, the vertically movable toe lasting mechanism A, the heel lasting mechanism B including the heel embracing band 3, the vertically movable toe rest C, the heel pin 2 having the brace, the holder 4 in which the pin is removably mounted near one edge, and the carrier 5 for the holder, said parts being constructed and arranged to permit the holder to be reversed for positioning the pin relatively to the band and to permit the pin to be reversed in the holder to locate the brace always in position to engage the last near its rear end, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
