HAT-PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 237,069, dated January 25, 1861.

Application filed July 12, 1880. (No model.)

To all whom in? may concern Be it known that we, CHARLES TYRRELL and EDWARD KEARNs, of Norwalk, in the county of Fairfield and State of Connecticut, have invented a new and useful Improvement in Hat-Pressing Machines, of which the following is a specification.

The object of our invention is to provide for more accurate and convenient adjustment and regulation of the pressure in machines for pressing hat-bodies.

Heretofore in such machines the die or block has been fitted upon a follower fitted for movement by a cam-lever to give the pressure required, the block being first adjusted; but in such machines the range of adjustment is limited, and considerable care is necessary to insure proper pressure.

We make use of an upright frame, the upper cross-rail of which carries a fixed mold and supports by adjustable rods a lower crossrail that is fitted for movement upon the side bars of the frame. Between the upper and lower rail of the frame is a cross-head, fitted for movement by toggle bars connected to the lower rail, and carrying the block or die, which is supported by a leg upon eccentrics or cams that are fitted for movement by a lever to raise the mold. The mold is first brought up bythe toggles, and the required pressure then given by the cam-lever.

The construction and operation will be described in detail with reference to the accompanying drawings, wherein Figure l is a front elevation of the machine. Fig. 2 is a vertical transverse section 011 line as a; of Fig. 1. Fig. 3 is a detail section on line y y of Fig. 1.

Similar letters of reference indicate corre sponding parts.

The frame, composed of side standards, a a, and top rail, 1), is supported on the floor or a suitable base.

At the lower ends of the standards a (t is placed a rail, 0, having mortises in its ends that set over guides d, that are fixed upon the the inner sides'ofthe standards and supported from the top rail, 12, by rods 0 c and nuts f f, so that the rail 0 may be adjusted to and from the upper rail.

Between the standards is fitted a head or follower, A, composed of cross-bars g g and posts h h, secured together by the rods 9, the nuts of which are loose to allow raising of the upper bar g, as hereinafter described. The lower bar 9 of head A and the rail 0 are connected by toggle-bars t, which are suitably jointed to the rail and bar. The lower toggle is jointed to the lugs of a casting, k, that is attached upon rail 0, which casting is also fitted with a cross-shaft, k, having an arm that connects, by a link, Z, with the joint-pin of the toggle-levers. Upon this shaft k is also fitted an arm, m, by which the shaft may be turned to move the toggles, which arm is to be suitably connected for operation by hand or foot.

At the under side of the top rail, 1), is rigidly attached the mold and upon the top bar 9 of head A the die or block 0 rests, a lug on its under side entering a mortise of the bar. To the under side of this bar 9 is attached a hanger, p, which is fitted in its lower .forked end with a lever, q, that is formed with a toothed cam which engages with a cam or eccentric, r, that is hung in suitable bearings on the lower bar g. The die 0 consists of an outer shell of metal, containing a bedding, 8, of elastic material, that is sustained-upon an interior metal form, .9. The lower side of mold n is shaped to receive the block, and between the elastic bedding 3 and metal mold 0 the bat is pressed.

By operating the arm m to bend the togglebars 2' the head A is brought down, and space thereby given for placing the bat upon the die, and by reverse movement of arm m the toggles are straightened and the die and mold brought together, with the bat between them. The rail 0 is to be adjusted so that this movement of arm m shall bring the hat to the shape required, or nearly so, and further adjustment may be made, according to the shape and size of block 0, by placing washers between block 0 and bar 9. After the head A is raised the pressure is to be given by pressing the camlever q down, which raises the upper bar, g, and die 0. Great pressure may thus be given to the extent required, and the movement is sufficiently long to compensate any inaccuracy of adjustment.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. In hat-pressing machines. the sliding 5 head A, carrying the block or die, toggles i, fitted for operation by an arm or lever, and adjustable rail 0, combined together and with the frame carrying the mold, substantially as shown and described.

2. In combination with the sliding head A and its supporting-frame, the rail 0, sustained from the fixed rail b by screw-rods e, and the toggle-bars i supporting the head, substantially as shown and described.

3. The cam-leverq and eccentric r, combined with the sliding head A and block a, substantially as and for the purposes set forth.

4. The head A, consisting of bars 9 g and posts a, tied together by screw-rods g, the cam-lever q, and eccentric 1, combined togo gether and with toggle mechanism for operating the head, substantially as and for the purposes set forth.
