ANTON J. SCHMIEDL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO EDWARD B. JORDAN, OF SAME PLACE.

LEATHER-BEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 472,609, dated April 12, 1892. Application tiled April 12. 1888- Serial No. 270,441. (No model.)

`To all whom, t may oon/cern,.-

Be it known that I, ANTON J. SCHMIEDL, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Leather-Beading Machines, of which the following is a specification.

My invention relates to machines for beading leather in general, and is particularly adapted to use in the manufacture of boots and shoes.

It consists of certain improvements, which are fully set forth in the following specification and illustrated in the accompanying drawings, which form a part thereof.

In the manufacture of boots and shoes and other articles in which two pieces of leather are sewed together it is customary to turn the pieces of leather inside out over the seam thus made to cover the rough edge, and the leather is then pushed out at this seam to present an even edge and subsequently hammered and sewed. This is the operation known in the art as beading; and it is to accomplish this effectively and speedily that my invention is designed. After the edges have thus been pushed out or beaded it is usual to flatten them down by hammering and ultimately sewing a line of stitches close to the edge; but my invention is concerned only with the former operation.

The state of the art prior to my invention is illustrated in Letters Patent No. 251,789, of January 3, 1882,. granted to James McGuigaii, in which isshown aiixed arm having an opening at its end ofV sufficient size to admit the seam of the leather which is to be turned. Within this fixed arm is a pusher connected to a lever, which is operated either by foot or hand to project forward the pusher, and thus `turn the leather. This machine would not accomplish the obj ect of my invention, which is to push out the leather on one side of the seam to form the beaded appearance and not to push out the seam itself. Y u

My improvement requires a rapid reciprocating movement from the pushing arm or blade, and the leather is worked over the stationary part by thc movements of the hands in opposition to the action of the reciprocating blade.

In the drawings, Figure l is a front elevation of my improved beading-machine. Fig. 2 is a side sectional View of the same through the line oo of Fig. l. Fig. 3 isa similar view, on a smaller scale, showing a modification of my invention. Fig. .tis a fiont elevation, on a smaller scale, of another modification. Fig.A 5 is a detailed View of the detached operating-wheel and cam or eccentric mechanism. Fig.,6 is a cross-sectional view of the beading blades or arms upon the liney i/,of Fig. 2. Fig. 7 is a detailed view of a modification of the beading blades or arms at their ends. Fig. 8 is a cross-sectional view of a piece of leather, showing the Operation of my machine in beading. Fig. 9 is a plan view of the same, and Fig. l0 is a cross-sectional view of the same after it has been beaded and sewed.

A is the frame or support of the machine by which it may be secured to a table and is provided with an arm or bracket B.

C is the operating-wheel and may be provided with a band connecting with a suitable power-wheel, or any other means may be employed to operate it or its shaft. This wheel is secured upon a shaft D, which is loosely journaled in the bracket B of the frame. I prefer to journal it, in the manner shown in the drawings, upon pin-bolts H, as this method greatly reduces the frictional resistance and allows for adjustment to prevent lost motion; but of course this is a mere detail of construction and not a limitation of my invention. portion of this shaft D near the wheel O is formed into an eccentric or cam part cl, upon which is bolted or otherwise secured eccentric-strap J, to which is hinged at K the central reciprocating arm or beading-blade E, the extremity of which I prefer to make into a flattened part e, and in the working of scallops-such as are shown in Fig. Q-this extremity should preferably be made rounded, as it is shown in the drawings. j

F is an upright arm consisting, preferably, of two parts secured together and havinga central slot or guideway G extending through or between them for the passage of the arm E in its reciprocations up and down. This arm F is rigidly secured to the bracket B, so that it remains motionless during the oper- IOO ation of the machine g butin the modifications of my invention the arrangement may be different, as is hereinafter explained.

The pieces of leather I, being sewed together and turned over on the seam fi, are placed over the end of the arm F, which is preferably rounded to correspond to the blade end c. The machine is put into operation and the extremity e of the arm E, which is normally just below or even with the ends of the arm F, reciprocates rapidly up and down into the bend formed by the leather and pushes it out, as shown in Figs. S and f),form ing the parts 'i2 and i3. W'hen this operation is performed in only one bend of the leather, as the edges of boots and slices, it is made into the form illustrated in Fig. l0, with part 'i2 projecting beyond part ci". The seam of the leather is now ready for the hammer, and after being hammered by hand or machine the seam is sewed with a line of stitchesft" near the edge, making the bead i3 more prominent.

In the old way of beading leather it was hard work on the girls hands pulling it over the fixed blade or beading-iron, and the operation was also slow. In my case, however,I cause the rapidly-reciprocating blade end e to push up the bead and the girl has simply to hold tlie leather in position over the arm F, so as to be acted on by the part e. If she holds steadily on to the leather, the reciprocations of the part e will be so rapid that the leather must give, assuming the desired form, rather than that the hands shall be drawn up and down. The work is far easier for the operator and the finish produced is more uniform.

In the modification in Fig. 3 the arm E is rigidly secured to the bracket B by a screw or otherwise, if desired, and the arm F hinged at K to the eccentric-strap .I or the eccentric (Z of the shaft D, so that this arm reciprocates, while the arm E remains motionless, producing substantially the same effect as in the former case.

In the modification of the invention in Fig. 4 the shaft D is provided with two cam parts d', to which the arms E and F are respectively journaled, and in this case both of the arms will rccipi'ocate, and the cam portions l are arianged diametrically opposite to produce an opposite recipi'ocation. If desired, one of the sides of the arms F may be cut away, as atfin Fig. 7, to make the end over which the leather is placed less thick, and the rear part of arm F gives a support for the operators hands in holding the leather.'

It is evident that in all of these modificationstliesamegeneralpiincipleiscarriedoutto wit, a relative reciprocation between the parts E and F, so that the part e is reciprocated beyond the part F, or vice versa. It is immaterial whether the reciprocations are imparted by the eccentric device shown or by any other suitable mechanical device, of which a large number could be readily adapted to the invention, and it is also immaterial to my invention, when more broadly considered, whether the part c iecedes below the end of the arm F or not, though I claim this specific species as apart of my invention. The main feature is to provide a suitable pushing-out device adjacent to act upon the leather without particular action of the operators handthat is to say, a device which acts upon the leather in contradistinction to a device which is acted on by the leather. It is self-evident that the important parts of the arms E and F are the free or outer ends or blade parts, or those parts which act upon the leather.

I do not limit myself to the mere details of construction here shown, as they may be manifestly varied in many ways without departing from the principles of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is*
