MACHINE FOR PRODUCING STITCH-IMPRESSIONS 0N SOLES FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters PatentNo. 267,702, dated November 21, 1882.

7 Application filed September 19, 1882. (No model.)

To all whom it may concern.-

Be it known that I, LYSANDER 0. MAKE- PEACE, of the city and county of Worcester, of the State of Massachusetts, have invented a new and useful Improvement inMachines for Producing Stitch-lmpressions on Soles for Shoes or Boots; and I do hereby declare the same to be described in thefollowing specification and represented in the accompanying drawings, of whichi Figure l is a front side elevation, and Fig.

invention, the nature of which is defined in the claims hereinafter presented. Fig. 3 is a rear side elevation in part. Fig. 4 is a top view of the guide-supporting bracket and the knifecarrieranditssustaining-carrier. Theremaining figures are hereinafter explained.

ter explained, such sole is bent and stitch-impressed along its edge upon the hair side of the sole, and the portion not bent down is pared, so as to cause the entire lower surface of the sole to be substantially in one plane. Thus the part stitch-impressed is part of the hair side of the sole, and when so stitchimpressed presents a smoother and far better finish, comparatively speaking.

Fig. 5 denotes a top view, Fig. 6 anedge elevation, and Fig. 7 a transverse section, of a sole as prepared by the aforesaid machine.

Fig. 8 is a transverse section of a sole-blank as bent on its hair side near each of its opposite edges, preparatory to being pared, or having a portion of the part bent down removed, in order to bring theentire lower surface of the sole in one plane. In this figure S is the sole-blank, A A the parts thereof bent down, while 0 6 denote the portion or strip pared off,

suchbeing triangular in transverse section.

In Figs. 1, 2, and 3, B denotes the machinearm, a, to which is fixeda bracket, l), carrying the stationary guide 0. J ou-rnaled in the gooseneck is a shaft, D, to be provided at its rear end with a driving-pulley. Near its front end such shaft carries the impression or marking wheel E, formed very like a spur-gear. Below the said shaft there is in the frame an arm, F,

pivoted at its rear part to the frame, and having pivoted to it at its front end aconical feedwheel, G. This arm rests upon aspiral spring, H, against the lower part of which a screw, I, screwed upward into the frame, bears. Over the feed-wh eel and revolvingfreel y on the shaft 1) is a conic frustum or bending-whee], K, and in advance of the bite of the feed and impression wheels is a paring-knife, L, which is supported by a carrier, M, pivoted to another carrier, N, which in turn is .pivoted to the bracket 12, so as tobe capable of turning in a vertical plane in order for the cutting-edge of the knife to rise or. fall with the feed-wheel G as the thicknessof the sole-blank may require. The said knife enters a notch ina slide, D, pivoted to the arm F, a connecting-bar, 0, being extended down from the said arm to the upper of two pedals, P and Q, arranged as represented, the said upper pedal resting upon a friction-roller, f, carriedby the pedal Q. By means of the upper pedal the feed-wheel may be moved downward away from the impression-wheel, and by means of the lower pedal such feed-wheel may be forced upward toward the said impression wheel, as occasion may require. The carrierNis provided with a setscrew, g, to act against the journal h of the knife-carrier M, the said carrier M being capable of being tur'ned,so as to give the proper inclination to the cutting-edge or front end of the knife.

In using the said machine, the sole-blank at its edge is to be laid against the guide 0 and introduced between the impression and feed and bending wheels. The driving-shaft,b eing to advance the blank and impress or mark it and force it against the paring-knife, which will pare it, the bending-wheel in the meantime bending down the blank so as to bring in the plane of the cutting-edge of the knife that part of the under side of the blank which is not directly underneath the impression-wheel.

frame, provided with-a goose-neck or curved in revolution, will cause the impression-wheel As the sole-blank continues to advance it will be stitch-impressed about its curved periphery and pared in manner as described.

Iam aware ofthe machines represented in the United States PatentsNos. 140,035 and 150,842,

the first being for bending the edges of boot and shoe soles preparatory to the sewing of welts thereto, and the second being for stitchmarking a sole and trimming it at its edge. Neitherof these machines hasa knife arranged as in my machine to pare off a part of the bentdown portion of the sole, so as to bring the ing wheels, and adapted to operate substantially as specified.

2. The combination of the pivoted or adjustable knife-carrier M, its pivoted carrier N, as described, and theknif'e-slide D,pivoted to the arm F, with the paring-knife, the stationary guide, and the feed, bending, and marking wheels, all being arranged and to operate substantially as and for the purpose or objects set forth.

3. The combination of the two pedals PQ, and the connecting-bar O with the arm F, the feed, marking, and bending wheels, and the paring-knife, all being arranged, supported, and adapted to operate substantially as set forth.
