SOLE-CHANNELING AND FLAP-TURNING MACHENE.

SPECIFICATION forming part of Letters Patent No. 602,980, dated April 26, 1898.

Application filed July 3, 1897. Serial No. 643,359. (No model.)

To all whom it may concern:

Be it known that 1, Hanson]; T. Cnosnv, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sole-Channeling and Flap-Turning Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to sole-channelin g and flap-turning maehines,and is an improvement upon the invention described in another application of mine filed May 24, 1897, and serially numbered 637,844; and it consists in certain novel features of construction, arrangement, and combination of parts,which will be readily understood by reference to the description of the accompanying drawings and to the claims hereto appended and in which my invention is clearly pointed out.

Figure l of the drawings is a side elevation of a machine embodying my invention. Fig. 2 is a front elevation of the same. Fig. 8 is a partial plan of the front portion of the machine with the feed-shaft and feed-wheel removed. Figs. 4, 5 and 6 are respectively a plan, a side elevation, and a front elevation, of the channel-cutting knife, the flap-turning blade or hammer, and the section of the vibrating lever to which they are secured. Fig. 7 is a perspective view of the channelcutting knife removed from its carrier. Figs. 8 and 9 are respectively a side elevation and an inverted plan of the flap-turning blade or hammer. Fig. 10 is a front elevation of the channel-cutter, flap-turner, and the lever for carrying the same 3 and Figs. 11 and 12 are respectively a plan and a transverse section of a piece of leather illustrating a channel having its flap turned as performed by my invention.

In the drawings, A is the frame of the head of the machine.

B is the drivin -shaft, C the driving-pulley, and D the knife-lever-operating crankpiu, said shaft B having formed thereon or secured thereto a worm (not shown) which engages with and imparts motion to the wormwheel F, firmly secured upon the feed-shaft G, mounted in bearings in the frame A. and having secured upon its front end the feed disk H and gage-r0111 and at its rear end the non-revoluble yoke or collar J, by which the lever K, rod L, and a treadle. (Not shown.) Said shaft G may be moved endwise in its bearings against the tension of the spring M.

N is a vertically-movable slide,'upon which are mounted the gage-r011 O, the vibrating lever P, the stationary cutter a, and the fixed presser-guide Z), said slide having a spring 0 attached thereto, the tension of which tends to move said slide downward.

Q is a cam-plate mounted upon a pin set in the frame A, about which it is movable in one direction by the rod (1 and a treadle (not shown) and in the opposite direction by the spring B, said cam engaging a pin 6, set in said slide N and operating to raise said slide when the rod (1 is moved downward.

The upward and downward movements of the slide N are limited by the stops f and f, respectively.

So far the machine is constructed and operates substantially as described in my beforecited application.

In my present invention instead of making the knifecarrying lever in one piece and pivoting the knife to its extreme front end, as in my former invention, 1 make said lever in two parts P and P, pivoted together at g, said part P being adjustable about said pivot to vary the angle of the channel-cutting knife h,by means of the clamping-screw i, the shank. of which passes through a slot t" in the rear end of the part P and is screwed into the part P, as shown. The: forward end of the part P has formed in its side a slightly curved rectangular slot j to receive the knife 72, which is clamped therein by the cap it, formed in one piece with the flap-turning blade or hammer 71;, said cap having a simi- 9o larly-curved rectangular slot j formed therein to receive one edge of said knife and secured to the part P by the clamping-screw Z and the steady-pin Z. By this construction the knife It may be formed on the end of a slightly-curved rectangular bar, as shown in Fig. 7, and it maybe adjusted endwise in its bearing as it is worn up by sharpening, and it may also be adjusted to enter the sole at difierent angles by means of the clampingzoo screw 7 as before described.

The flapturning blade 70 is secured to the part P of the lever P, as above described, with its inner edge coinciding with the contiguous edge of the knife 71 and in contact therewith, as shown in Fig. 6. Said blade has its operating end curved, so that while the portion 2 next to the knife his somewhat shorter than said knife, or, in other words, its lower end is above the lower end of the knife, its opposite edge portion 3 has its lower end considerably below the level of the lower end of said knife, as shown in Fig. 6. The curved lower end of said blade 7c has formed therein near the cutting-knife h a shallow curved notch 4, as shown. The blade 70 also has its front face curved, as shown in i Fig. 9, so that while the part 2 of said blade enters the out made by the knife h the curved notch at engages the edge of the flap as said blade is reciprocated and turns said edge outward, and the curved portions 3 and 5 complete the turn-in of the flap and by the rapid impact thereof firmly sets the flap in its turned position, the parts 3 and 5 being outside of said flap. By this construction and operation of the channel-cutting and flapturning devices moving in a direction at right angles to the line of feed of the material being acted upon a perfect channel is produced and fully prepared to receive the sewing at one operation, which is a very material advantage over cutting the channel at one operation and turning or opening it by a separate and distinct operation, as is now generally the practice.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a channel-cutting machine the combination with a feeding mechanism of a vibratory lever made in two parts connected together and adjustable one upon the other by means of a pivot-pin, and a clamping-screw the latter passing'through a slot in one of said parts concentric with the axis of said pivot-pin, and set in a fixed position in the other of said parts; a channel-cutting knife clamped to the movable end of said lever and adjustable in the direction of the length of said knife; and means for vibrating said lever in a vertical plane at right angles to the line of feed of the material.

2. In a channel-cutting and flap-turning machine the combination with a feeding mechanism and a fixed cutter arranged to cut a shallow incision in the material as it is fed past it, of a vibrating cutter moving in a vertical plane at rightangles to the line of feed and adapted to out a succession of incisions in the material at a slight angle to the face of material; and a flap-turning blade in close proximity to and movable with said vibrating cutter.

3. In a sole channeling machine the combination with a feeding mechanism and a fixed cutter arranged to cut a shallow incision in the face of the material, as it is fed past it, of the vibratory lever P P made in two parts pivoted together and adjustable one upon the other; the cutting-blade 7?, and the turner 7t 7t secured to the lever P P and arranged relative to each other as set forth; and means for vibrating said lever in a vertical plane at right angles to the line of feed of the material to be acted upon.

4. In a sole-channeling machine the combination of the rotary feed-disk H; the revoluble gage-rolls I and O; the fixed pressure gage I); the fixed cutter a; a vibratory lever movable in a vertical plane at right angles to the line of feed; the cutter h and the flapturning blade 7:, both carried by said lever; and means for imparting a short and rapid vibration to said lever substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 30th day of June, A. D. 1897.

HANFORD T. CROSBY.
