CHARLES H. BAYLEY, OF BOSTON, MASSACHUSETTS.

SEAM-PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 643,455, dated February 13, 1900. Application filed May 13, 1899. Serial No. 716,647. (No model.)

To aZZ whom, it may concern.-

Be it known that I, CHARLES H. BAYLEY, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Seam-Pressing Machines, of which the following is a description sufficiently full, clear, and exact to enable those skilled in the art to which it appertains or with which it is most nearly connected to make and use the same.

This invention relates to machines for pressing and smoothing the seams, hems, and similar features of leather manufacture, so as to finish or complete the same or to suit it for further operative steps in the process of manufacture.

It is the object of the invention to so improve seam-pressing machines and machines for cognate purposes as that they may be used with greater facility and to accomplish the work much more expeditiously than heretofore.

It is also the objectof my invention to render the machines simpler in construction and more durable than they have previously been, to the end of securing substantial economy both in construction and use.

To these ends the invention consists of the improved machine hereinafter described in detail and particularly pointed out in the claim.

Reference is to be had to the annexed drawings, and to the letters marked thereon, forming a part of this specification, the same letters designating the same parts or features, as the case may be, wherever they occur.

Of the drawings, Figure 1 is a side elevation of the machine embodying my improvements. Fig. 2 is a plan view of the same. Fig. 3 is a vertical sectional View taken on the line 3 3 of Fig. 2.

In the drawings, a designates the bed or base of the machine, from the rear standard part b of which there extend forward two arms 0 0, between the ends of which the lever d is fulcrumed on the pin a. The lever 01 is forked at its rear end, and a journal-box f is arranged to reciprocate in said fork, the crank part 9 of a shaft It being arranged to operate in said journal-box and the shaft having a pulley or pulleys i secured to it, by which it is adapted to be rotated. The shaft of course is suitably journaled in the standard b.

j designates the hammer, plunger, or pounder, which is supported vertically in a suitable guideway in the front end of the lever and-is pressed or held down to normal position by a quite-powerful spring is acting thereon, the nuts Zm, turned on the upper end of the plunger, limiting its downward movement. A washer n, of leather or similar material, is interposed between the support for the shaft of the plunger and the nut Z, so as to cushion the blows between the two.

0 designates the hollow screw-threaded shank of the bed 19, which shank is adapted to be screwed up and down in what is substantially an interiorly-screw-threaded pinchcollar q, formed on the forward end of the base a, so that the bed may be adjusted up and down in its support. Holes r are formed in the periphery of the bed to receive a pin or other means for turning the bed to adjust it, and a bolt 8 is extended through one projection on the pinch-collar and tapped into the other to fix the shank of the bed in position when once it is adjusted to proper position.

t designates the bed-plate, which is provided with a shank a, adapted to extend down through the hollow shank 0 of the bed, so as to maintain it in position. Interposed between the bed 19 and the plate 15 is a washer '0, of leather or other suitable material, to cushion the blow of the plunger j upon the material between it and the bed-plate. The shank u of the bed-plate will be sufficiently loose in the hollow shank to permit the bedplate t to turn with the material being operated upon.

In the operation of the machine, a belt being applied to the pulley t' the leverd will be oscillated quite rapidly and the plunger will of course be operated in like manner, so that seamed material passed between the plunger j and the'bed-plate i will be acted upon and pounded or smoothed down with great nicety, and if thick places should be encountered the spring pressing down the plunger will of course yield, so that the plunger will not act with too great energy or force. As before stated, in turning material being operated upon by the plunger the fact that the bed-plate t is constructed to turn on its shank will greatly facilitate the operation.

The vertical adjustability of the bed is for the purpose of suiting the machine to varying thicknesses of leather.

Provision is made, it will be seen, so that the bearings of all the movable parts may be freely lubricated.

The great advantages of this machine are its simplicity, the readiness with which it may be adjusted, the facility with which the work of the seam-pressing may be performed, and its strength and durability generally. The cushioning of both the plunger and the bed-plate are things that cushion the violence of the blows and deaden the noise, so that it may not be objectionable.

Having thus explained the nature of the invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, it is declared that what is claimed is- In a machine of the character described,

the combination of a lever having atubular head; a hammer having a stem extending through said head; a spring surrounding the stem within the head between shoulders of the latter and the stern; a stop-nut on the stem above the head; and sound-deadening or cushioning material interposed between said nut and the head.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 18th day of
