MACHINE r012. ROUGH-ROUNDING AND LAsrmesmcnEn-nown SHOES.

in connection with the accompanying draw.

ing, is a specification, like characters on the drawing representing like parts.

This invention has for its object to provide a novel machine for simultaneously rough rounding and lasting stitched-down shoes, thus performing at one operation the lasting of the upper and the trimming of the sole. I

Features of the invention consist in means to force the upper into the angle between the side of the last and the projecting margin of the sole, means for pressing the marginal portions of the upper and sole together thereby toperform the lasting operation, and means operating simultaneously to trim the edge of the sole at the required distance from the last. 1

In the presentmachine the shoe being operated on is held against a work supporting element which also functions to tuck the upper into the corner between the last and will be now described, after which the novel features will be claims.

In the drawings, Figure 1 is a side view of pointed out in the appended a machine embodying my invention.

Fig. 2 is a front view thereof.

Fig. 3 is a top lan view.

Fig. 4 is a sectlon on the line 4-4, Fig. 1.

Fig. 5 is a section on the line 55, Fig. 3.

Fig. 6 is a section onthe line 6-6, Fig. 3.

The principal parts of the device comprise a work supporting member qr work-guiding Specification of Letters Patent; Patented Nov, 29, 1921, Application filed October 13, 1920. Serial No. 416,605

, member against which'the projecting portion of the sole of the shoe is held and which also operates to force the upper into the angle between the side of the last and the projecting margin of the sole, a presser element or beater constructed to act on the under face of the sole at the margin sole and press or beat the marginal portions of the sole and upper portions together, and a" trimming knife which operates to trim or rough round the sole.

These parts are suitably mounted upon a frame 5 which may have any suitable shape adapted for this purpose. V

i The work-holding or work-guiding device comprises a plate 6 secured to the frame 5 and a member 10 in the form of a truncated cone which overlies the plate 6 and cooperates therewith to support and guide the shoe and which also by its shape operates to force the upper into the angle between the side of the last and the projecting portion of the sole. In Figs. 1 and 6 I have shown a portion of a shoe on a last, 1 indicating the last, 2 the upper of the shoe, 3 the sole there} of and 4 the marginal portion of the upper which is to be stitched to the marginal portion of the sole. -In operating on a shoe.

the latter is held, as shown in Figs. 1 and 6 with the portion thereof projecting beyond the last placed against the work-holding device, and the operator will move the shoe relative to the work holder so that the latter will follow around the last and in doing so the work is pressed against the member 10.

Situated beneath the member 10 is a presser elementor beater 7 which is reciprocated vertically and which cooperates with the

elements

6 and 10 to press together the marginal portions of the upper and the sole. The trimming knife, by which the sole is trimmed, is indicated at 33 and this is also arranged to have a reciprocating movement.

The beater or presser member 7 is yieldingly mounted on a slide or carriage 8 which is sli'dable vertically on ways 9 formed on the frame 5. This slide 8 is shown as having thedove-tail ways 29 formed therein and the beater or presser member 7 is provided with an extension 28 which slides in the ways 29. through which extends an adjusting screw. 30, that is screwthreaded into thelower end Said extension has a hub 49' of the carriage 28. Said screw has a hand wheel 31 on its lower end and a spring 32 encircles the screw 30 and is confined between the hub 49 and the hand wheel. Said spring thus makes a yielding support for the presser member 7. The slide or carriage 8 is reciprocated vertically on the Ways 9 and for this purpose said slide 8 is provided with rack teeth 23 which mesh with teeth 22 formed on one end of a lever 20 pivoted to the frame at ,21, the other end of said lever 20 being connected by a link 19 to a crank pin 18 carried by a shaft 15 which is rotatively mounted in the frame. Said shaft is shown as having fast and

loose pulleys

16, 17 thereon by which it may be driven.-

The presser member 7 is preferably so adjusted by the screw 30 that when the slide 8 is raised the presser member will engage the under side of the sole before said slide reaches the upper limit of its movement, so that during the final upward movement of the slide the spring 32 will be compressed thus producing a yielding pressure against the sole.

The trimming knife 33, by which the sole is trimmed, is secured to the slide 8 and by such upward movement of the slide the trimming knife cuts through the sole, thereby trimming the latter, the plate 6 constituting a cutting bed against which theknife acts.

In Figs. 1 and 2 the slide is shown as raised and the beater 7 is pressing against the sole and the cutter 33 has cut through the edge of the sole. When the slide is at the lower limit of its movement the expanding action of the spring 32 will raise the presser member 7 relative to the knife so that the face of said presser member will be above the cutting edge of the knife. When the carriage 8 moves upwardly therefore, the presser member 7 is first brought against the bottom of the sole and as the carriage continues its upward movement the spring 32 is compressed and the knife is brought into position to cut through the sole and trim the latter, as shown in Fig. 1. As the shoe is moved around the work support, 6, 10, the member 10 forces the upper into the corner between the side of the last and the projecting portion ofthe sole, the beater or presser member 7 presses the marginal portions of the sole and upper together and the cutter trims the sole, thus performing the rough rounding operation. I

It will be noted that when the cutter comes into action the marginal portions of the sole and upper are clamped between the work support and the presser member 7 so that the shoewill be firmly held during each cutting operation.

In the present embodiment of the invention the member 10 is shown as havinga reciprocating motion parallel to the sole. This is accomplished by mounting the member 10 on a slide 11 which is provided on its underside withdove-tailed ways 12 which receive the uiding member 13 formed on the frame 5. aid slide 11 is connected by a link 24 to a crank pin 25 carried on the end ofa shaft 26 which extends parallel to the shaft 15 and is geared thereto by suitable gearing 27, which is constructed so that the two

shafts

26 and 15 rotate at the same speed.

The member 10 is provided on its under face with a recess to receive the plate 6, said recess being sufiiciently larger than the plate to permit the necessary reciprocating movement of the member 10 relative to the plate. This member 10 is in the form of a truncated cone and is freely rotatable in the slide.
