Specification of Letters Patent.

- Application led July 22, 1896. Serial No. 600,133.

To all whom it may concern;

Be it known that we, ERASTUS E. \VINK- LEY and FREDERICK L. ALLEY, citizens of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Lasting-Machines; and we do hereby declare the following to be a full, clear, and exact description of theinvention,

such as'will enable others skilled in the art to which it appertains to make and use the same.

The present lnvention relates generally to machinesof the class above designated, andv devices hereinafter more specifically' set' forth in this specification and defined in the claims.

The present invention isillustrated in the drawings herewith submitted in which- 'Figure 1 is a side-elevation partially in section showing a portion of the frame, the head which carries "the heel lasting devices, and other associated parts of a lasting machine embodying the present invention, Fig. .2 is a section on line mm F 1g. 1, the upper portion of the headlbeing removed, Fig. 3 is a reverse plan view of the head, some of its associate parts being shown in section. Fig. 4: is a sectional plan view on the line yy, Fig. 1, Fig. 5 is a sectional elevation of the parts shown in Fig. 4 on the line ez of said figure, and Fig. 6 is a detail sectional view taken on the line 6-6 of. Fig. 3.

Similar letters-ofreference refer to similar parts throughout the several views.

In the drawing A representszaportion of the frame which supports the working parts of the machine and which may be and conveniently is of substantially the same constructionias' that of the machine shown and center f as a center.

described in Letters Patent of the U. S. No. 521,954 issued to the Goodyear Shoe Machinery Company as ass'igneeof E. F. Grundy, dated June 26, 1894.

In the frame A are formed suitable longitudinal ways (not shown) in which is mounted a carriage B free to slide along said ways substantially as in said patented machine.

Pivotally supported at b on the carriage B is the tipping bed plate C, in which is formed the longitudinal, preferably dovetailed, groove 0, to which is fitted a correspondingly shaped block of on the sliding bed D. In the bed D is formed the segmental slot (P, to which is fitted a block 0, on the laterally movable head E. The head E carries the last clamp orband F, from the central portion 7 of which as a center the slot (Z is struck. The head E. also carries the usual lasting plates or wipers which may be like those in said prior patent to Grandy, hereinbefore referred to. The above described arrangement is snch't-hat the clamp or band F is movable from or toward the last H independently of the carriage B, and has a laterally swinging movement about its In other wordstlie movement of the block (3 in its, guiding slot at transmits to the last clamp or band F a curvilinear lateral movement to adapt it to the position of the end of the last adjacent the band.

By the swinging movement of the clamp or band F above referred to we accomplish the adjustment of the clamp or band F for right and left shoes and said movement may be conveniently secured by means of a seg-' mental worm gear 6 fixedly secured to the head E, and which engages with worm (5 which is mounted'upon and rotates with a short shaft (i mounted in suit-able bearings d on the'bed D. The shaft (i may be actuated by a hand wheel (Z or any other suitable means.

The heel band or clamp F may conveniently consist of the strip or chain f carrying the yielding facing pad 7, as is common in this class of machines.

In accordance with the present invention the clamp or band F is pivotally secured at opposite sides "to the inwardly bent arms L, L, which are arranged to move laterally toward and from the median line of the.

' scribed.

Y L, blocks 1, and

carriage E, with a parallel lateral motion so that the ends ofthe clamp F are thereby moved toward and from the median line of the last.

In the form of our invention shown in the drawings we secure the above suggested movement as follows :-Each of the arms L, L is fixedly secured to transverse or plates 1, .mounted and free to slide in suitable transverse grooves in the under side of the forwardly projecting portion of the head. To suitable longitudinal ways inthe under side of'the forwardly'projecting portion' of the head E, are fitted the slides Z P, which are free to slide in said ways, but are held by said ways from any lateral movement. On the arms L, L are formed or secured the inclined shoulders 1 ,1 and Z V, which abut upon the oppositely inclined shoulders 2 and Z Z upon the slides Z and P. A suitably placed spring preferably'the' bent spring Z is provided, which is arranged vto' bear against the arms L and keep the shoulders Z and Z in contact, when the slides Z are moved as'hereinafter de- The slides l and Z are ea,ch connected to the head E, by means of a suitably placed spring, vpreferably the coiled springs 25, each of which is connected at one end to the head E, or projections e thereon, and at the other end to one of the slides 1 The arms, slides Z, are supported on the under side of the forwardly projected portion of head E, by means of gibs 6*, e orzother suitable means, and the above described arrangement is such that a forward motion of the slides Z causes the blocks Z to move inwardly in their transverse grooves carrying the arms L inward with a parallel lateral movement, advancing the ends of the band or clamp F toward the median line.

and causing the clamp or band F 'to closely embrace the upper upon the last. When the slides P- are advanced as above stated to laterally close in the clamp or band F, they act also by means of their spring connections t, t, with the head E. to slightly advance the head E to insure a proper pressure of the band or-clamp F at the back of the heel.

Each of the slides Z is connected by an independent yielding connection, preferably a coiled spring'h, with a movable cross head H, or other suitable device, the arrangement being such that of the last bring the other side into contact with the upper, thus insuring theproper set of the bloclts' scribed in vices, and a last clamp or band F on both sides of the last. The head H may be conveniently advanced and retracted by means of a lever h (Fig. 1), upon which it is formed or secured, and which may be conveniently actuated by mechanism shown in part in the drawings, but of which no further description is regarded as necessary herein, substantially the same mechanism being shown and described in Letters Patent of the United States, No. 521954 hereinbefore referred to.

As heretofore stated the bed plate C has a longitudinally tipping movementand may be conveniently supported and adjusted by mechanism similar to that shown and de Letters Patentof the United States No. 55283-1 issued to the Goodyear Shoe Machinery Company June 7 1896 on the invention of-E. F. Grandy, and which,

.as we claim no invention therein, we have notherein described drawings.

I In the foregoing specification and in the claims we have made use of the terms inward, outward, lateral and longitudinal 7, as descriptive of the action of the various instrumentalities; thus the frame A has suitable longitudinal ways which extend in the direction of the length of the last when in the machine, in which the carriage B has a sliding. movement. The tipping bed C has a groove running in the same direction as the ways in the frame A. ,The band F has a lateral or sidewise swinging movement about the center f. The arms L, L which carry the band F have a lateral movement toward and from each other. The blocks Z have an inward and outward movement toward and from each other.

We do not consider our present invention as limited to the specific construction herein shown and described, but

We claim as novel and desire to secure by Letters Patent of the United States? 1.
