SEAM-PRESSING DEVICE.

SPECIFICATION forming part of Letters Patent No. $76,606, dated June 7, 1892.

Application filed November 3, 1891. Serial No. 410,765. (No model.)

To all w/tom it may concern:

Be it known that I, JOHN E. BROWN, a citizen of the United States, residing at "SK ashington Court-House, in the county of Fayette and State of Ohio, have invented certain new and useful Improvements in Seam-Pressing Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide improved pressing or flattening devices for use more especially on that class of machines designed to turn and press the scallops and seams of shoe-uppers. V.

The improvements consistin the construction and combination of parts herein described, and particularly pointed out in the claims.

In the accompanying drawings, forming a part of this specification, Figure l is a side view, partly in elevation and partly in section, illustrating an embodiment of my improvements; and Fig. 2 is a front elevation, with parts of the turning mechanism broken away.

Like letters denote corresponding parts in the two figures of the drawings.

Referring to said drawings, the letter A designates a table, upon which is supported a bed plate B. Secured to the rear part of the bedplate is the presser frame or standard O,while upon the front portion of said bed-plate is fixed a horn or standard D, carrying the scallop or seam turning mechanism. Pivoted to the standard 0 is a lever O, which has connected with its upper end a forwardly-extending horizontal arm 0 The front portion of the arm is held and supported so as to be horizontally reciprocable in suitable bearingsupon the top of the forwardly projecting part of the standard 0. A dependent end portion of this arm 0 carries a presser-disk B of the seam compressing or flattening device. The other or stationary portion of the seampressing device consists of a disk or head D provided with a shank or rod on, held by means of a pin c in a screw-threaded tube or socket-piece p in the end of the standard 0. The threaded tube or socket-piece p is made with a flange m, and between this flange and the disk or head D I propose to place an elastic packing-ring m of rubber or other material, so that the disk or head D will yield should the material placed between the presser be so thick as to render it liable to be unduly crushed under the blows of the disk D. The fact that the socket-piece p is threaded permits the adj ustme'nt thereof for compressing seams of different thicknesses.

Upon the threaded socket-piece 19 turns a check-nut 12, having a finger-piece n, whereby the said socket-piece may be locked in any position to which it may be adjusted.

Pivoted upon the front of the standard 0 is a lever O, the upper arm of which is connected by means of a link 0 with the lever C, while the lower arm is provided with a presser or beater, which acts against the adjustable disk or head seated in the standard 0. The stationary part of this seam-presser resembles that at the top of the standard 0, and it is therefore unnecessary to describe again the several parts of which it is composed.

Connected with the lower end of the lever O is a bar or link P.

Ashaft Q, provided with any suitable means for applying driving-power thereto, is journaledhorizontally in the bed-plate, so that a crank-pin q on one end of said shaft may engage the forward end of the bar or link P.

The operation of the machine is as follows: The rotation of the shaft Q, causes the link or bar P to reciprocate horizontally, thus rocking the lever O. This rocking of the lever O, as is obvious, causes the presser-arm C to reciprocate, and with it the disk or hammer D. The rocking of this lever C also causes the link 0 to reciprocate, and with it the rocking of lever 0.

As the seams at some parts of an upper are thicker or heavier than at others it is der able that pressers whose faces do not approach each other with equal propinquity be provided. Hence I have added the second presser, the stationary face of which maybe adjusted to suit the seams of diiferent thicknesses.

The subject-matter herein set forth is also IOG 1. In a seam pressing or flattening device, the combination, with a support or standard, of a vibrating head or hammer, a stationary head or disk having a shank adapted to fit within a tube or socket-piece, the said tube or socket -piece constructed to receive the shank and provided with a flange, an elastic packing interposed between said flange and the stationary disk, and means for securing the said tube or socket-piece in different adusted positions on the standard,substantially as shown and described.

2. In a seam pressing or flattening device, the support orstandard provided with a screwthreaded socket, a vibrating head or hammer, a stationary head or disk having" a shank adapted to fit within a tube or socket-piece, the said tube or socket-piece constructed to receive the shank and com plementarily screw: threaded to engage the socket in the standard, a flange on said tube, and an elastic packing interposed between the flange and stationary disk, in combination, substantially as shown and described.

3. The combination of the standard C, the lever O, fulcrumed in said standard, means for rocking the same, the stationary disk or head D the arm or bar 0 havinga beater or presser at one end and pivotally connected with the lever C at the other and supported and sliding in suitable bearings, so as to be reciprocable longitudinally with respect to itself upon said standard and the said bearings, substantially as shown.

In testimony whereof I aflix mysignaturc in presence of two Witnesses.
