Nrrn STATES JAMES M. HARRISON, OE ROCHESTER, NEW YORK, ASSIGNOR TO THE ROCHESTER SHOE MACHINERY COMPANY, OF SAME PLACE.-

PATTERN-PLATE.

SPECIFICATION forming part of Letters Patent No. 463,603, dated November 17, 1891. Application tiled June 15, 189].. Serial No. 393,327. (No modeL My present invention has for its objects to provide an improved former or pattern plate particularly adapted for machines in which a .cutter or marking-tool is made to traverse a certain path to mark or cut goods according to the contour of said patterns, but which can be used as a pattern to mark or cut goods by hand.

I-Ieretofore it has been necessary to employ a separate former for each different style of article, and as their first cost is considerable a great outlay is necessary to perfectly equip a factory where a great variety of goods is made.

With the object in view, therefore, of reducing the cost of the devices and at the same time increasing their usefulness my invention consists in an improved former, which can readily be adjusted for any style of article; and it further consists in certain novelties of construction and combinations of parts, all as will be hereinafter described, and the novel features pointed out particularly in the claims at the end of this specification.

In the accompanying drawings, Figure lis a side view of a button-fiy-scalloping machine, showing the application of my inven-l tion thereto. Fig. 2 isa sectional view on the line x of Fig. l, showing the former in plan; Fig. 3, a plan View of the former, showing the manner of adjusting it; Fig. 4, a horizontal sectional View; =Fig. 5, a longitudinal and Fig. 6 a crosssectional view.

Similar reference numerals and letters in Vthe several iigures denote similar parts.

I have show-n my improved former applied to a machine for scalloping button-flies for shoes, such as is c ontained in Patent No. 372,618, dated November l, 1887, D indicating the cutting-chisel; E, the head thereof; F, the

arm carrying the chisel; L, the plate for depressing the chisel; M, the ratchet-segment for limiting the lateral movements of arm F; N, the spring for rotating arm F; O, the spring drawing the chisel inward and holding it against the former; P, the catchco-operating with the ratchet-plate, and Q the latchfor operating it, actuated by the stationary arm R when the plate L is reciprocated.

The parts are well known, and therefore their specific construction and operation need not be herein described further than that the plate L is depressed to bring down the head carrying the cutting chisel, the lateral movement of which is governed by the ratchet-plate, the cat-ch releasing one tooth and allowing the spring to move saidhead to the next, when the plate L is moved upward after cutting one scallop. ments of the chisel are governed by the edge .of the former or pattern-plate l, forming the The radial move-k subject of my present invention, said former being adapted to be mounted on standards or posts 2, secured to. a presser-plate, as ordinarily, to the bed of the machine, or it may be secured to any other suitable support, or, if desired, used without a support resting on the goods themselves. Y

In making my former I prefer to employ a frame consisting of two plates 3 and 4, connected together at opposite ends by suitable blocks 5, leaving a space between them sufficient for the accommodation of a series of blocks or slides 6, each having a pin 7, projecting from its upper surface near the outer end, and preferably rounded off on the outer end, so that whenin extreme inward position, with the pins T engaging the edge of upper plate 3, (which is preferably curved, as shown, or another suitable stop,) said ends will also form a practically continuous curve.

IOO

cutting-chisel or marking device is held, and its contour is regulated by the projection of the blocks, and'deterinines that of the article being cut or marked.

At one or both ends of the frame carrying the movable blocks is a screw 12, operating when screwed in to cla-m p the blocks together and to the frame, holding them in their adjusted position.

The operation of setting the former or gage will now be understood. The operator is provided with a number of patterns 13, Which may be of Wood or light metal and provided with a small pin in one end, as shown in Fig. 3 in dotted lines, each pattern having the contour of the button-Hy or other article it is desired to form. Assuming the blocks 6 are all retracted, with their pins 7 against the edge of plate 3, the operator, taking one of the plates 13, being the pattern he Wishes to eut or mark, inserts its pivotal pin in the aperture in plate Sand turns its free end outward, as in Fig. 3, when its edge will engage the pins 7 and move the blocks G outward until the strip 9 is in proper position, conforming to the edge of pattern 13, when the blocks are secured by means of the screw 12 and the former is ready to properlyguide the tool operating against the strip. This former could be used Whenever desired and for whatever purpose, the machine to which it is shown attached being but one of the many Ways in `which it may be utilized--as, for instance, it could be used with goodettect for cutting the uppers of shoes, the operator passing his knife around the edge the same as he now does with a single metallic pattern-plate.

Numerous modifications could be made without departing from the spirit of my invention, as the outer strip 9 could be dispensed with and other means employed for retracting the sliding blocks, and instead of providing the pivot-pin on the pattern-plate 13 the latter could be moved into position, being guided in its movements by suitable means. However, I prefer the arrangement shown, as

I have found it admirably adapted for the purpose.

It will be understood that instead of setting the former by means of the pins on the sliding blocks the edge of the pattern 13 could, it desired, be placed against the rear ledges of the blocks, moving them and the strip 9 outward the required distance.

I claim as my invention- 1. The combination, with the frame, of the series of abutting and longitudinally-movable blocks arranged therein, having the curved faces for the ready passage of a cutting or marking tool, and also the projecting pins for the engagement of the edge of a pattern, and the clamp for securing the blocks together and to the frame, substantially as described.

2. The combination, with the frame, of the series of abutting and longitudinallyfmovable blocks therein, the flexible strip, supporting devices for holding said strip against the blocks and forming a smooth surface for the operating-tool, and a clamp for securing the blocks together and to the frame, substantially as described.

3. The combination, with the frame, of the series of abutting and longitudinally-movable blocks therein having the projecting pins for co-operating with the pattern, the tiexible strip-supports for holding it against the outer ends of said blocks and forming a smooth surface for the operating-tool, and a clamp for securing the blocks together and to the frame, substantially as described.

et. The combination, with the frame, of the series ot' sliding blocks therein, each having a pin projecting above the top of the frame,

the strip of spring material at the outer ends of the blocks and guides for it, a spring connected to said strip, and aclamp in the frame for securing the blocks in adjusted position, substantially as described.
