HEIVIMING ATTACHMENT FOR SEWING-MACHINES.

Specification of Letters Patent.

retell-tea rep. an, alert.

Application filed February 7, 1916. Serial No. YB/ 794.

-; and State of Massachusetts, have invented certain new and useful Improvements in Hemming Attachments for Sewing Machines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved hemming attachment for sewing machines, and

has for its primary object to provide a device of this character which may be readily attached to or removed from the machine whereby hems of various widths may be turned in the material and stitched as the.

material is drawn under the presser foot.

The invention has for an additional object to provide a device for the above purpose embodying a slotted gage plate provided with means for attaching the same to the presser foot standard, a hem turner slidably and adjustably mounted upon the gage plate and over which the material is drawn.

It is another object of the invention to provide a simple and effective device for turning wide hems in the material, said device being applicable to the ordinary sewing machine without necessitating any alterations whatever therein. a

With the above and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a perspective view showing my improved hemming attachment applied to a sewing machine;

Fig. 2 is an enlarged longitudinal section through the device;

Fig. 3 is a detail perspective view of the adjustable hem turning plate.

Referring in detailto the drawing, 5 indicates the needle bar of a sewing machine, 6 the presser foot bar arranged contiguous thereto, and 7 the preSSer foot suitably at tached to the lower end of the latter bar. These bars are of any ordinary or approved construction, the present invention being applicable to various types of sewing machines now in common use.

My improved hemming attachment i11- cludes a gage plate 8, the medial portion of which is provided with parallel longitudinally extending slots 9. Beyond the slot at one end of the plate, one of the longitudinal edges thereof extends obliquely inwardly, as at 10, and from this narrowed section of the body plate a relatively wide wing 11 extends,

and this wing is bent at its juncture with the end of the body plate inwardly and under the end portion of the plate to lie in spaced parallel relation thereto, At the juncture of the wing 11 with the obliquely inclined edge 10 of the gage plate, a notch or recess, indicated at 12, is cut in said wing. The gage plate is disposed in advance of the presser foot 7 and the vertically reciprocating needle, indicated at N, is in line with the notch 12. The raw edge of the material is turned under and drawn through this notch, said turned edge being stitched to the body of the material. One end of the wing 11 which extends in substantially parallel relation to the oblique edge 10 of the body plate, is upwardly and inwardly bent upon itself, as shown at 13, and over the same the edge of the material is drawn.

The other end of the plate 8. has an angularly disposed transverse flange 14: formed thereon which is adapted to rest upon the bed or table of the machine.

16 designates the hem turning plate which is preferably of the form shown in Fig. 3 and is bent upwardly at one end, as at 17, and provided with an inwardly extending terminal portion 18 disposed in parallel relation to the body of the plate. Spaced screws 19 are fixed at one of their ends in this terminal portion 18 of the plate and project upwardly through the respective slots 9 in the gage plate. Clamping nuts, indicated at 20, are threaded upon the ends of these screws, whereby the hem turning platemay be securelyclamped in its adjusted position withrespect to the gage plate. The latter plate is graduated, as at 21, 011 its opposite longitudinal edges along the slots 9 in said plate.

To one longitudinal edge of the plate 8, at the end thereof which is provided with the inwardly projecting wing 11, the end of a bar 22 is riveted or otherwise securely fixed. This bar is formed of relatively heavy metal and projects laterally from the edge of the plate and is then extended upwardly at right angles to the plane of the plate 8. ()n the upper end of this bar, a horizontally projecting arm 23 is formed which is provided with a central bend or seat 24 for engagement upon one side of the presser foot rod or bar 6. Screws are fixed at one of their ends in this arm 23 and a clamping plate 26 is adapted to be engaged upon the opposite sideof the rod 6 and is provided with openings in its ends to receive the screws 25. Suitable clamping nuts are threaded upon the ends of these screws, whereby the device may be securely clamped in connection with the rod 6 or readily adjusted thereon.

In the operation of the device, the same is applied to the presser foot rod of a sewing machine, as shown in Fig. 1, and the edge of the material is inserted between the plate 16 and the gage plate 8. This plate 7 16 has, of course, been previously adjusted so as to position the flange l7 thereon in accordance with the selected graduations on the scales 21 which determines the desired width of the hem. The edge of the material is then turned over and extended outwardly over the wing 11 and the inturned flange 13 thereon. The turn or bend in the material is engaged against the vertical flange 17 of the plate 16. As above stated, when the material is drawn over the curved edge 13 of the wing 11 and under the plate 8, the raw edge of the material engaging the bend in the plate at the juncture of the wing therewith, is turned under as it moves through the notch 12 and subsequently stitched to the underlying body portion of the material. The material will be continuously and automatically turned to form the hem as it is drawn between the

plates

8 and 16. Thus, by simply loosening the clamping nuts 20 and properly adjusting the plate 16 with respect to the gage plate 8, a hem of any desired width may be turned on the edge of the material.

From the foregoing description, taken in connection with the accompanying drawing, the construction, manner of use and several advantages of my invention will be clearly and fully understood. The attachment may be very easily and quickly applied to the sewing machine or removed therefrom, and provides simple and reliable means for accurately turning a wide hem in the edge of the material. The adjustment of the hem.

turning plate can also be very reading effected. The device, as a whole, comprises very few parts which are all of exceedingly simple form and it is, therefore, apparent that the attachment can be manufactured at relatively small cost. The device is designed for use upon various types of sewing machines without necessitating any changes or alterations in the construction thereof.

While I have shown and described the preferred construction and arrangement of the several elements, it is to be understood that the device is susceptible of considerable modification therein and I, therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is A hem turning attachment for sewing machines including a relatively fixed. graduated gage plate provided with an angular flange on one end to rest upon the bed of a machine, the other end of the plate beingreversely bent and disposed in parallel relation to the body of the plate, said latter end of the plate and the contiguous body portion of the plate having their corresponding longitudinal edges obliquely inclined and the returned end portion of the plate being provided with an upwardly and outwardly turned bead on its inclined edge, a hem turning plate disposed in spaced parallel relation beneath the gage plate and provided upon one end with a flange against which the edge of the material engages and by which the same is turned to form the hem, and adjustable means on the flange of the hem turning plate to co-act with said gage plate and clamp said flange against the under side thereof.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
