HENIMER ATTACHMENT FOR SEWING-MACHINES.

" SPECIFICATION forming part of Letters IPatent 0. 753,891, dated March 8, 1904.

Application fil d January 23, 1900. Serial No. 2,448. (No model.)

To all whom it may concern 7 Be it known that I, ALEXANDER LAUBSOHER, a citizen of the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Hemmer Attachments for Sewing-Machines, of which the following is a specification.

My invention comprehends a combined I guide, folder, and hemmer for sewing-ma chines, and has for its object the production of a device which shall be simple in construction, yet effective in operation, and capable of automatically folding anunderturned hem upon the outer raw edge of the material for a shirt-bosom, around and inclosing the edge of an underlying interlining in the manufacture of shirt-bosoms preparatory to sewing them upon'shirts.

In the accompanying drawings, which form a part of this specification, Figure 1 represents a perspective view of the folder of my apparatus as looked at from above; Fig. 2, the same when viewed from below; Fig. 3, the 5 interliriing-suppoirt; Fig. 4,, the base-plate; Fig. 5, a side elevation; Fig. 6, an end elevation, and Fig. 7 a perspective view of the apparatus complete. Fig. 8 is an exaggerated cross-section of fabric, illustrating the fold 3, made by the device of this invention.

All figures show parts somewhat enlarged,

' the better to show their construction.

The folder which I employ is constructed of sheet metal and is shaped somewhat like the scroll of a binder used on sewing-machines, as shown at A in Fig. 1. The upper lip a of the folder is not, however, provided with a return-bend, as in binders, but projects into space in order that the overlying material for 4 the shirt-bosom may pass beneath and enter the guiding passage-way a by the convolutions of which it is turned first downward and inward and againupward and outward, as in the formation of a hem, as it advancestoward the delivery end of the folder. While the upper lip a is continuous fromthe entrance to the delivery, the lower lip is so divided as to practically constitute two members, as shown at a and of, both of which are turned inwardly to form a continuous passage-way 5 and guide, the entrance to which is shown at the point where is located the reference character a for the underturned edge of the bosom; but the portion a not only extends inwardly far enough to form such guide, but is continued upwardly and outwardly and also toward the tip a of the folder to serve as a support for the edge of the bosom and keep it separated from the underlying lining of the same. As a support for the underlying lin- 0 ing of the bosom I construct a plate, as shown at 6, (see Fig. 8,) having a depending angle 7), and attach the same beneath the lip a with said angle portion secured to the lower and inwardly-turned lip a and its straight edge 5 secured to the concave surface of the outwardly-turned lip a as seen in Fig. 5.

As ameans of attaching the folder and guide to the sewing-machine, the convex surface of the folder A is secured to the member C, 7 which I will term the base-plate, as shown in Fig. 4, which is provided with an orifice for the passageof a screw by means of which the base-plate is secured to-the bed-plate of the sewing-machine in such relation to the needle that the latter will puncture the upper ply, the lining, and" the under ply and lay the stitches at a uniform distance from the underturned edge of the bosom.

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

1. A sewing-machine hemmer attachment, comprising a folder having an upper folding and guiding lip, and a divided lower lip to hem-fold the edge of an outer fabric, such as 5' a shirt-bosom, around and inclosing the edge of an underlying fabric or lining, a plate arranged between the members of the divided lower-lip and adapted to support and guide the underlying fabric, and means for support- 9 ing said folder in operative position.

2. A sewing-machine hemmer attachment, comprising a folder having an upper folding and guiding lip, and a divided lower lip having a fabric passage-way between its members to turn one piece of cloth around another in the form of an underturned hem, said lower lip having two members arranged in differthe members of the divided lower lip and at tached to the member a thereof, and a baseplate.

Signed at Bridgeport, in the county of Fairfield and State of Connecticut, this 22d day of January, A. D. 1900.

ALEXANDER LAUBSCHER.
