MACHINE FOR MANUFACTURING STIFFENERS FOR BOOTS R SHOES.

SPECIFICATION forming part of Letters Patent No. 319,873, dated June 9, 1885.

Application filed March 9, 1885.

To all whom it may concern:

Be it known that I, J OHN M. WILLOUGHBY,

1 detail sectional view of the post or upright end piece, 19, to show its mouth r.

In operating the machine, which is hereinafter more fully described, a flat blank of well-known form and of suitable material,

usually leather or leather-board, is rolled and curved lengthwise, while its straight edge is bent and pressed to form a flange, thus producing what is known as a flanged and rolled counter; and my invention consists in the combination, in such a rolling-machine, of a concave and a convex roll, a concave presserrol-l mounted in adjustable bearings behind the convex roll, and a rigid end piece arranged, as hereinafter described, to act upon the flanged end of the counter-blank as it passes through the rolls and press and set it to shape to form the flange of the rolled counter.

To all skilled in the art the concave and convex rolls, as also the method of mounting them in adjustable bearings, and of gearing the shafts together and to a driving-shaft, as shown in the drawings, are well known and will not require a detailed description.

0 4 provide the upright frame parts 0 C of the machine with the arms a a, projecting rearwardly, and to the ends of said arms I bolt the cross-pieces (1. Through the cross-pieces 5 d, I set the screw-bolts f, which bear on the blocks h, in which is mounted the shaft 70. This shaft carries the concave presser-roll m, which, as will be obvious, may by the sllding In mounting the adjustable presser-roll I (No model.)

blocks h and screws f be set to or from the convex roll n, thus enabling the operator to obtain a greater or less amount of pressure upon the blank as it passes between the rolls on and n. The shaft 70 of the concave presserroll is driven by means of gears which connect it with the shaft of the convex roll n. It will be obvious that by varying the size of the gears used to connect the three shafts any of these rolls may be driven at a relatively greater or less speed.

At the end of the rolls I provide an upright, p, which is securely bolted to the bed of the machine. (See Figs. 1 and 4.) This piece acts upon'the edge of the counter-blank which projects beyond the end of the rolls while the blank is passing between them, which projecting edge is thereby pressed and-,rubbed against the end of the convexroll and forms the flange of the counter. In order that this flanged edge may be gradually bent and 7 turned over and against the end of the convex 7o roll as the blank passes through, I provide the'uprightp with a concavity or mouth,r,(see Fig. 5,) of a depth where the flange edge enters it nearly equal to the width of the flange, (see Fig. 1,) and gradually lessening in depth 7 until it disappears. As the blank enters the rolls, the flange edge enters this cavity or mouth 1, and as it passes through is gradually turned over and against the end of the convex roll, and after passing the mouth r is rubbed and pressed against said end by the flat inner face of the upright 12. In this manner the flange is evenly and smoothly pressed and set. The upright piece .9 is the edge-guide of well-known construction.

What I claim is The combination, with a concave and convex roll and an adjustable presser-roll, of the rigidly-set end piece, p,provided with a mouth, o whereby the flange is turned and set, substantially as shown and described.

JOHN M. WILLOUGHBY.
