IMPROVEMENT IN HEMMERS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 144,649, dated November 18,1873; application led September 27, 1873.

To all 'whom it may concern:

Be it known that I, WILLIAM LEE AP- THORP, of Tallahassee, in the county of Leon and State of Florida, have invented a nenT and Improved Adjustable Hemmer, of which the following is a specification:

My invention consists of a hem-turning scroll for the edge of the cloth, permanently attached to the ends of a piece of wire, which constitutes the frame by which saidscroll is supported and attached to the machine, and on which a scroll-guide for the fold of the cloth is fixed so as to slide toward and from the edge-turning scroll to suit the width of hem required, the wholev comprising a very simple, cheap, and etiicient attachment for making liems of any required width.

The drawing is a perspective view of my iinproved hemmer adapted for use on the Wheeler and Wilson machine.

A represents the edge-turning scroll, which is a thin piece of sheet metal bent into semicircula-r form, or thereabout, at the end a, at which the cloth enters, and having the edge b gradually extended spirally toward a complete circle, but tapered and llattened so that at the end d, where the cloth is delivered to the needle, it is contracted in such manner that it turns the edge of the cloth neatly under, and lays it flat as it goes to the needle and presser, thus making the inner edge of the hem. The other edge of the hem, consisting of the fold of the cloth, is made by the folding scroll and guide B, which consists of a straight concave plate, arranged to ont the scroll A. The

scroll A is attached to the ends of wires C by the ears l) on its upper edge. These wires are bent downward at E, or connected to others, F, extending back under C to the scroll A, or nearly to it, and connected together by the piece G. The wires C are arranged about as high above wires F as the height ofthe scrolls A B. The latter scroll is connected with a flat plate, H, itted on wires F, so as to slide toward and from scroll B to regulate the width of the hem. A little plate, I, with a slot, J, is attached to one of the wires F for securing the attachment to the cloth-plate of the machine by a thumb-screw. The slot allows of shifting the scroll relatively to the needle to have the hein sewed more or less distant from the edge, as may be required. The scroll B, with its plate H, is shifted toward and frolm scroll A to adjust it to the width of hem` required. The wire frame C F G is constructed of one piece.

This hemmer can be adapted for other machines by slight modifications of the attachingplate.

Having thus described my invention, I claim as new and desire to secure by Letters Batent The scroll A, formed as described, adjustable scroll B, the frame C F G, and attachingplate I, combined, constructed, and arranged substantially as speciied.

WILLIAM LEE APTHORP.
