SHOE-UPPER-TURNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 380,959, dated April 10, 1888.

Application filed January 30, 1888. Serial No. 262.455. (No model.)

T0 @ZZ whom 'it may concern.-

Be it known that l, FRANK D. WaLDnN, a citizen of the United States, residing at Jeffersonville, in the county of Clark and State of Indiana, have invented a new and useful Improvement in Shoe-Upper-Turning Machines, of which the following is a specification.

My invention relates to an improvement in shoe-upperturning machines; and it consists in the peculiar construction and arrangement of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

The accompanying drawing is a View in vertical perspective of a s'hoe-upper-turning machine embodying my improvements.

A represents a hollow pyramidal standard rmly secured to the frame of the machine X, formed in two sections fastened at any point, and so constructed as to contain an upright shaft, U, rounded and attened at its upper end and having an offset pivot with a frictionroller at its lower end, and is allowed a free up-and-down motion in the standard,in which suitable bearings are provided. To this shaft a reciprocating movement is communicated upward by a cam-wheel, N, on the horizontal shaft S, and downward by the coiled spring H, which also serves to hold the oftset pivot and its roller ofthe upright shaft onto the periphery of the cam-wheel.

G represents a presser irml y secured to the frame of the machine X, consisting of the standard g, supporting the ears o e and terminating in the vertical surface T, and the presserarm B,worling in the ears c c of the standard g, and its presser-plate K,working against the corresponding surface T of the standard g, and connecting at b with the connecting-rod D.

D represents a connecting-rod connecting the presser-arm B at b with a cam-lever, L, at Z, and composed of two sections connected by the right and left screw-nut I. The cam-lever L, connected with the conne'cting-rod,has its offset and friction-roller pressed upon the periphery of the cam wheel M by means of the spring e.

S represents a shaft rotating in the hangers V W, and carrying the two cam-wheels M N and the pulley-wheel J.

F represents a lifting device actuated by an ordinary foot-lever (not shown) engaging the shaft II under the collar E, and so arranged as to disengage and keep disengaged the shaft U from the cam-wheel N at will.

The mode of operation of the above-described machine is as follows: The shaft S is driven by suitable belting,and the power applied may result from steam or any suitable mechanism. The cam-wheel N, working against the offset, and the coiled spring pushing against the collar, communicate to the shaft U a reciprocating movement up and down, its extent being governed by the shape and size of the wings of the cam-wheel. Over the upper end of the uprighta workman slipsashoe-upper,as shown in dotted lines, and allows the shaft to penetrate each scallop in its turn, and to force it out to an extent permitted by the seam. Vhile this movement is in progress the parts of the upper turned by the foregoing process and movement are brought in succession between the jaws of the presser G, where they are flattened or beaded by a series of pressings or beatings produced as follows: By means of the cam-wheel M and the spring e a reciprocating movement is imparted to the lever L,which in turn imparts, through the connecting-rod D, to the presser-arm B a rapid succession of movements against and from the stationary head and plate T of the standard g. Should the shoe-upper have a plain unsoalloped edge, then the upright shaftU should be stationary, and the shoe-upper should simply be drawn over it. vrIhe upright shaft is rendered stationary as follows: The long arm of the lever F is drawn down. By this means the shaft is lifted up and removed from engagement with the camwheel N. The pressing process is the same as for the scalloped upper.

The force of the pressing or beading process is regulated by the length of the connectingrod D,whioh is shortened or lengthened by the right and left screw-nut I. i

By my machine I obtain these advantages over this process. The shoe-upper is not removed to another machine to be pressed, that operation in my machine being a continuation of the turning process.

The operation of pressing, owing to the rapidity of the movement of the presser, is more expeditious than the old process of hammering,while, owing to the uniformity of the beat- IOO ings of the presser-arm, there is no opportunity to break the leather at the seams by an unusual] y heavy blow-,a mischance quite common to the old process.

I am aware that a machine exists wherein the turning of each scallop is accomplished by a corresponding depression of the treadle. My machine has the advantage over this of possessing mechanical means for turning the scallops without the intervention of the workman, and in greater rapidity of movement and uniformity of work.

I am also aware that there has been a turning device patented in which au up-anddown movement is given to a pusher working in an inclined projecting standard with a movable end, and is itself made in sections and actuated up and down in a slanting direction by a lever and foot-treadle. In this device, also, as foot movement is no faster than hand movement, and as'the device has no multiplying mechanism, it has little or no advantage over the old stationary finger in economy of time and labor. In my device, supposing steampower to be applied to the horizontal shaft, its large number of rotations would be converted into thrice the number of movements of the upright shaft, provided a three-winged cam-wheel be used.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. A shoe-upper-turning machine in which devices for turning the edges of shoe-uppers and for pressing the same are combined, consisting of the standard A, attached to a suitable frame, X, the upright shaft U, to which areciprocating movement up and down is given by the cam-wheel N and the coiled spring H, the presser G, likewise attached to the frame X, composed of the fixed standard g, and t-he presser-arm B, actuated by the cam-wheel M, and the lifting device F, all substantially as described.

2. A shoe-upper-turning machine consisting of two standards, A and G, attached to the frame X, the standard A constructed to admit freely the shaft U, and having a recess adapted to receive the coiled spring H, the standard G consisting of the arm g, supporting the presser-arm B, attached to it between the ears c c byvapin, the connecting-rod D, the lever L, the shaft S, supporting the camwheels M and N and the pulley-wheel J, and the lifting device F, substantially as described.

3. In a shoe-upper-turning machine, the frame X, the standard A, the standard G, the connecting-rod D, connecting the presser-arm B with the lever L, formed in two sections, y and z, connected by the extension screw-nut I, the lifting device F, the cam-lever L, the

shaft S, supporting the cam-wheel M, which f.

actuates the presser-arm B through the lever L and the connecting-rod D, and the cam-wheel N, which actuates the upright shaft U and the pulley-wheel J.

4. In a shoe-uppe1-turning machine, the upright shaft U, rounded and flattened at its upper end to form a turning-iron, supporting the collar E and resting by means of an otiset and friction-roller against the periphery ofthe camwheel N and working freely in the standard A, and supporting a coiled spring jammed between the collar E and the standard at P, the lifting device F, its lever catching the shaft under the collar and adapted to remove the shaft U from engagement with the cam-wheel N, the presser-arm B, constructed to press the edge of a shoe-upper between its surfacek and the head ofthe standard g, and the shaft holding the cam-wheels adapted to actuate the upright shaft U and the presserarn1 B by means substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
