No. 484,366.. Patented Oct. 11, 1892.

UNITED STATES PATENT QFFICE.

FRANK HENRY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE PENNSYLVANIA INDUSTRIAL DEVELOPMENT COMPANY, OF SAME PLACE.

HEM FOLDER AND PRESSER.

SPECIFICATION forming part of Letters Patent No. 484,366, dated October 11, 1892.

Application filed July 8,1892- Serial No. 439,386. (No model.)

To all whom it may concern:

Beit known that I, FRANK HENRY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Hand Hem Folders and Pressers; 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.

My present invention relates to hand hemfolders, and has for its object certain improvements on the device shown in the patent granted to me on the 2d of March, 1875, and numbered 160,429, which improvements will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification, Figure 1 represents a perspective of my invention; Fig. 2, a vertical transverse section on the line a: 00, Fig. 1; and Fig. 3, a vertical longitudinal section onthe line y y.

Reference being had to the drawings and the letters thereon, A indicates a clamp having a jaw a and screw 17, passing through an arm 0, for securing the device to a table or other like structure for use. At the upper end of the vertical armd of the clamp is a horizontal plate B, provided with a groove 6 near one edge to receive a vertical flange f on the hemmer O, a stud g, which passes through the plate, and a leaf-spring h, secured to the under side of the plate and to which the stud g is secured to hold the hemmer in position on the plate by engaging a slot l in the hemmer, and the head of the stud resting upon the bottom plate 7.0 of the hemmer.

D indicates the presser, which crosses the plate B transversely at a right angle to the line of passage of the fabric and is substantially-U shape, one arml of which is journaled in lugs 'm'n, projecting from the under side of the plate B, and on said arm l is a cam-like projection 0, which engages a leafspring 19, secured to the arm 0 of the clamp, and between which leaf-spring and the arm 0 is a helical spring q to apply tension to the other arm 0" of the presser, which normally rests upon the plate B and holds it down upon the fabric as it proceeds from the hemmer properly folded and presses the hem with sufficient force to 'fix the folds in the fabric. The arm 1" crosses the table upon its upper side in the rear of the hemmer O, and may be raised out of contact with the fabric by turning the presser on the arm Z, the extent of its motion being limited by the projection s on' the free end of the spring 10, as shown in full and in dotted lines in Fig. 3.

Having thus fully described my invention, what I claim is I. In a hand hem-folder, a plate having a groove, a stud extending through the plate, and a spring to which said stud is attached, in combination with a hemmer provided with a'vertical flange anda slot to engage the stud.

2. The combination of a plate, a hemmer supported thereby, a two-arm presser having a bar connecting said arms, one of said arms being pivotally supported in bearings beneath the plate and the other arm crossing the plate in rear of the hemmer and above the plate, and a spring acting upon said presser.

3. The combination of a plate, a hemmer supported thereby, a two-arm presser having a bar connecting said arms, one of said arms being provided with a cam and pivotally supported in bearings beneath the plate and the other arm crossing the plate in rear of the hemmer and above the plate, and a spring acting upon said cam.

In testimony whereof I affix my signature in presence of two witnesses.
