SPECIFICATION forming part of Letters Patent No. 519,162, dated May 1, 1894. Application filed November 23,1893. Serial No. 491,776. (No model.)

.To all whom it may concern:

Be t known that I, ANTONIGNATZ SCHMIEDL, a citlzen of the United States, and a resident of the city of Philadelphia, in the county of Ph1ladelphia and State of Pennsylvania, have lnvented certainnew and useful Improvements in Shoe-Beading Devices, of which the following is a specification.

My invention relates to devices for form- [0 ing an even edge for stitched shoe seams in which the stitched and turned edge is pushed or forced out from; the inside to present a regular line preparatory to the operation of hammering the turned stitched edge to flatten and make it of smooth and regular finish. In shoe uppers the leather is sewed to the lining and the sewed pieces are then turned right side out to inolose the rough edges of the stitched parts. The infolded or turned in seam of] the leather edge is then pushed out from between the sewed parts against the line of stitching for the purpose of. giving a uniform edge to the seam, so that when the seam is flattened out the edge will be smooth and regular. This flattening is done by hammering as the work is moved over an anvil. The seam is then finished bya line of stitching close to the turned edge. For effecting this seam finishing work I have produced an 3 improved beading device which I will now describe in connection with the accompanying drawings and will point out in the claims concluding this specification the parts and combinations of parts which constitute my in- Vention. i Referring to the drawings: Figurel represents in perspective a machine embracing my improved beading device. Fig. 2 is a verticalsection of the same. Fig.3 is a front 4 View of such device. Fig. 4 is a side view of the same. Figs. 5 and 5 show the double faced cam for actuating the front seaming finger or blade. Fig. 6 shows a piece of the scalloped upper illustrating the beading action of the front finger or blade in pressing out the edge of the scallops. Fig. 7 shows in cross sectional View the action of the front seaming finger or blade upon the turned leather at the stitched edge. Fig. 8 shows a similar view of the action of the back seammg fingeror blade in pushing out the top of the scallop. Fig. 9 shows the seam after it has been beaded and flattened; and Fig. 10 shows the position of the fingers or blades when the rear finger is acting as in Fig. 8.

As I have devised the seaming fingers or blades they are arranged on the opposite sides of a fixed-finger a, and the movement of the. front finger b, is lateral and to the right side only of the fixed finger a, while the rear finger c has a vertical movement. While the front finger I) is acting against the leather to ceive a short shaft 6 which has fixed thereon a driving pulley f, on one side of which is a double faced cam g g, and on its other side is an eccentricQh, the function of which ll will presently state.

The fixed finger a is forked at its lower end to permit the placing and working of the drive pulley, cam and eccentric. Upon the back of the fixed finger is connected the finger or blade 0 by means of screws '5, 11, which pass through slots 0 c, in said finger to permit it to have a vertical reciprocating movement imparted to it by the eccentric h which the back finger embraces by its yoke end 0 Upon the front side of the fixed finger is connected a similar finger or blade I), by means of screws j, j, to permit it to have alateral reciprocating movement imparted to it by the double faced cam, and a co-acting spring 7a. For this purpose this finger has a short cross slot j through which the lower screw passes to hold the finger properly in place. These mov-- able fingers terminate in thin fiat rounded ends b c, at the rounded end a of the fixed finger with which they co-operate to push out andspread the stitched folded part of the leather in, a way which Ishall presently state. A spring Z0 is connected to constantly press lthelower end of the front finger 12 against the face of the double cam. The cam isdivided diametrically to form identical acting faces 9 g for the purpose of giving to the finger four vibrations to the one revolution of the cam; while the eccentric gives by one revolution, to its connected finger, an upward and downward movement.

The relation of the front finger b to the rounded end a of the fixedfinger and to the cam, is such as to cause the beading end of the front finger to move only beyond the front sid'eof the fixed finger so that its right edge will act against and push out one side of the scallop, While the left edge of the fixed finger a will act to hold the work against such pushing action as seen in Figs. 3 and 6, the work being moved by the operator over and upon the beading fingers to the left as indicated by the arrow 2. This pushing movement of the finger is very quick against the inner side of the fold at the line of stitching and regular edge along the stitched parts.

arms of the operator holding the work, and it.

' is evident that the finger acting twice on the same side and part of the scallop, will give a better and smoother outward pressing action than would result from a single pressing action of the finger on the same part of the seam or scallop. In this seaming operation, the stitched edge when the leather is turned right side out, is so adjusted upon the fingers as to bring the inner lapped and stitched edge outside or in front of the front-finger so that the three fingers will be between the lapped leather parts and will act wholly upon the leather and not upon the lining, as seen in Figs. 7 and 8. The cam stands with its greatest points of elevation in the line of the greatest elevation of the eccentric, so that while the front finger is acting against the right side of the scallop, the back finger will act against the top of the scallop above the top of the fixed finger as seen in Fig. 10. It is important to observe that the spring acts to give the front finger its pushing action as seen in Fig. 3, against the scallop and thereby cushions such action and prevents its liability to burst the line of stitching, so that the cam acts only to move the finger b to the left and to compress the spring so that it will act to move the finger to the right while the cam is traversing its lowest part g against the spring pressed end of said finger. The front finger having two pushing vibrations during one revolution of the operating cam gives the advantage of a quick action without increasing the speed which in such machines is about sixteen hundred revolutions per minute,'and more completely pushes out the seam at the points of the joining of the scallops; while the back finger has a positive and limited movement up against the full curve of the scallop and against which pushi'ng action thework is held by the hands of the operator. It is the double pressing action of the front finger on the same part of the scallop during one revolution of the cam that allows the latter to be run with less speed, and lessens the bad effect of the jarring upon the hands and arms of the operator; and it is theindependentaction of the two fingers-one sidewise, and the other upwardthat gives to the seam and to the scallop its proper shape and regular finish; and it is the relation of the movement of the front finger to the fixed finger that causes the latter to support the left side of the scallop while the front finger is pushing and forcing out the right side of the scallop away from the fixed finger.

The eccentric strap 0 may be provided with an adjustable wear-pad Z, see Fig. 2, preferably of leather on which the eccentric acts and by which lost motion from wear may be taken up by means of a screw on pressing through the strap and bearing upon the pad which may be secured to the inner side of the strap. The cam acting end of the front lever may have a leather wear plug n bearing on the cam to prevent wear, as in Fig. 3. The

scalloped edge having been properly expanded and given its proper uniform shape, the work is then laced upon the anvil of ahammering device to flatten and finish the beading as seen in Fig. 9, and for this purpose I attach the beading device to a base which contains a hammer device, as seen in Fig. 1. I make this attachment by forming a socket r in the end of the base to receive the upper step part 8 of the beader casting, and firmly support it upon the bench by the aid of screws to passing throughthe base and clamped upon the stepped casting, so that the two devices may be sold as one machine for beading and hammering, but both not necessarily operated at the same time. As this seam hammering device is made the subject of a separate and distinct application for apatent filed of even date herewith a description thereof is deemed unnecessary herein and no claim is made to such device in this application.

I claim as my improvement- 1. In a shoe beading device, the combinaion of a fixed finger blade, a finger blade mounted on the front and a finger blade mounted on the back of said fixed finger, the said back finger having avertically reciprocating movement and the front finger having a laterally reciprocating movement, and mechanism for operating said movable fingers, substantially as described.
