SEAM-BEATING MACHlNE.

SPECIFICATION forming part of Letters Patent No. 324,086, dated August 11, 1885.

Application filed May 4, 1885.

To all whom it may concern.-

Be it known that we, CHARLEs W. CoLLYnR and WILLIAM G. CoLLYER, both of Lynn, county of Essex, and State of Massachusetts, have invented an Improvement in Machines for Hammering and Beating Out the Turned Seams in Leather-Fork, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In the manufacture of boots and shoes and other articles composed in whole or in part of leather it is customary to stitch together two plies or layers of material with their right sides or faces together, and to thereafter turn the said material to present the right sides outward, and to do this well requires considerable time and skill, and especially is this the case when the seam is provided with a corded or other welt.

The object of our invention is to provide a mechanism whereby two plies of leather or other material sewed together along one or more edges, and with or without a cord or other welt, may be readily and easily turn ed and be thereafter bent or hammepedout smooth, our machine beiln'g'ffespecially desirable for use in turning the button-pieces and the quarters of button and other boots and shoes.

Our invention consists, essentially, in a machine for hammering or beating out the turned edges of material sewed together wrong side out.

We have provided the bedplate or frame of our machine with ahorn or turning device, upon or over the end of which the material to be turned right side out is pushed in the process of turning the same.

Figure 1, in side elevation, represents a machine embodying our improvements, and Fig. 2 a top or plan view thereof.

The frame-work A, of suitable shape to support the working parts, has mounted in it a shaft, B, having an attached belt-wheel, 13*, provided with preferably an adjustable tappet, O, the said tappet, as herein shown by dotted lines, being made as a toe provided with a shank inserted in a diametrical hole in the said shaft, and being held in adjusted po- (No model.)

sition by a screw, D. The cars A of the frame A receive between them the rear end of the hammer lever or carrier F, provided with bosses 2 2, which fill the spaces between the said ears, and a short shaft, G, is extended through the said ears, and also through the said lever or carrier in the line of the bosses, the lever or carrier being thereafter connected or fixed with relation to the said shaft by a screw or pin, H.

The lever or carrier F herein shown has its front end made round, as shown by dotted lines, Fig. 1, to receive the hammer a, which is shown as insert-ed therein and made reversible, as it sometimes happens that the work may be best done by means of a hammer of metal, and at other times by a non-metallic face-such, for instance, as wood.

The end of the hammer uppermost in Fig. 1 is shown as provided with a nonmetallic core or face, a. The end of the lever or carrier F is provided with a spring-catch, I), held in place by a screw, H the catch having suitable points or projections to enter notches in the hammer, thereby holding the same in vertical position, the hammerbeing reversible when the spring is drawn back, so as to remove its projections from the recesses in the hammer.

The lever or carrier is held normally down by a suitable spring, as at c, interposed between the bracket 0! and the top of the said lever or carrier, the lower end of the spring setting on a lug or projection, 0 of the lever or carrier, the spring being made adjustable as to its strength by the adjusting-screw 0 the said spring being compressed each time the lever or carrier is lifted by the cam (J, and becoming effective to throw the carrier and hammer down quickly as the end of the cam passes the corner 8 (see dotted lines, Fig. 1) at the lower side of the carrier or lever F.

The frame has at its upper side a work-supporting plate, 10, on which, is laid the leather or other material having the turned seam which is to be beaten or hammered out. The lowest position of the hammer is regulated by the stop d", made preferably as a screw, having its upper end bored to receive a plug of leather or other sound-deadening material to act as a cushion, the screw being adjustable to place the stop in proper position to arrest the hammer at the point desired, or so as to strike the material on the worlcsupport with the desired force. The turning device is shown as a horn or finger, f, attached to the frame by a screw, f. and being held in working position by a catch, f

\Vhen two pieces of leather placed face to face and stitched together near their edges, with or without a welt or piping, are to be turned face side out to be made up into a boot or shoe or other article, the edges of the material next the seam, and while the material is wrong side out, are pressed against the upper end of the turning devicefafter a manner well known and practiced in such cases, and the said pieces of leather previously sewed togethcr wrong side out are turned to present their face sides out, and thereafter the seam has to be pounded or beat out by hand, and when the seam has a welt or a piping or cord this requires considerable care and is a slow process; but in accordance with our invention, with the power-actuated hammer, the said seam is readily and quickly pounded or beat out smoothly and uniformly.

e do not broadly claim a power-actuated hammer.

We claim 1. The frame-work, its shaft and adjustable cam, and the work-supp0rt, combined with the hammer carrier or lever, its attached hammer, and a spring to depress the said lever or carrier, substantially as described.

2. The frame-work, its shaft and cam, and the work-support, and the lever or carrier, combined with the reversible hammer, substantially as described.

3. The frame-work, the work -support, the lever or carrier, and the hammer actuated by it, combined with a turning device to assist in turning the material right side out preparatory to hammering or bending and finishing the seam, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
