LOUIS SOHULTZ, OF COLLEGE POINT, NEW YORK.

IMPROVEMENT IN HEMMERS FOR SEWING-MACHINES.

Specication forming part of Letters Patent No. 142.519, dated September 2, 1873; application filed July 9, 1873.

To all whom it may concern: v

Be it known that I, LoUIs ScHULTz, of College Point, in the county of Queens and State of New York, have invented a new and useful Improvement in Hemmer for Sewing- Machines; and I do hereby declare the following to be a full, clear, and exact descriptical section taken on the line x ac, Fig. 1.

Fig. 5 is a vertical section of the folded fabric after it has been operated upon by myimprovement.

Similar letters indicate corresponding parts.

This invention relates to an improvement in hemmers; and consists of a certain combination of parts, to be hereinafter described.

In the drawing, the letter A designates a piece of cloth under operation by my improvement, and B is the hemmer-plate, which is fastened to the table of va sewing-machine in the usual manner. One end of the plate B is provided with a scroll, G, of the usual construction, and I combine with the hemmer a folding-guide, D, consisting of a bar bent or formed substantially as shown, so as to support and guide a hem both within and without. The4 folding-guide I) is supported 'on a movable stock, E, which is held by an adjusting-screw, F, up against the underside of the hemmer-plate, the folding-guide being made adjustable on said plate, so that its supporting and guiding parts can be moved farther away from, or nearer to, the scroll G, as desired, by means of a slot, G, through which passes the screw F, as is represented most clearly in Fig. 1. The outer edge of the folding-guide stock E is square, and is arranged with the direction or line of movement of the cloth through the sewingmachine; and on said stock is formed a ledge or guide, H, extending transversely, and in an oblique direction, across the under surface of the hemmerplate, terminating opposite the discharging end of the hemmer. From the near end of the ledge H rises a bar, I, which is extended transversely to the receiving end of the hemter being carried out a sufficient distance, is"

bent down to the level of the bottom of the hemmer, and then carried backward and out- Ward until it is nearly in line with the guiding-ledge H, when its end J is bent so as to come in front of and parallel to the said ledge, the distance between them being sufficient to admit the thickness of the cloth to be operated upon.

In using that portion of my improvement thus far described, the cloth A is placed face downward, and the edge to be hemmed is turned up infront of the ledge H, and over the inside guide J, and pulled sidewise, until the edge to be hemmed is introduced into the 'hemmen As the cloth is moved along, the` hem is formed, and also folded and guided and kept symmetrical and straight, by the inside guide J and the outside ledge or guide H, and by the oblique position of the ledge H and guide J the fabric is constantly drawn into the hemmer, and the correct operation of the device isinsured. The hem is fastened by the same line of stitches, as is indicated by the drawing. The width ot' the hem is governed by means of the slot and screw above mentioned.

In order to give to the hem a smooth iinish and take out wrinkles from the cloth, I'have provided on the left-hand edge of the hemmer-plate, observing Figs. 1 and 4, a ange, K, which projects downward near enough to thesupporting-table over which the cloth moves to iron it out as it is fed along, and take out any creases or redundancies that may be found therein, so that the hem will be presented to the needle in a smooth condition, the redundancies in the hem being continually pulled back by the iange.

The flange Kean be formed either on the edge'or bottom of the hemmer-plate, asV desired.

What I claim as new, and desire to secure by Letters Patent, is-

The slottedgplate B, having the scroll C and its edge turned at K, in combination with the adjustable stock E, with oblique ledgeV H and bar I, with free end J parallel with the ledge, all constructed and operating as described. L. SCHULTZ. IVitnesses:
