SEWING MACHINE ATTACHMENT Filed Dec. 28. 1942 ..974 Inventor Elzas ,Elea/ei? Patented Aug. 15, 1944 UNITED STATES PATENT OFFICE SEWING-MACHINE ATTACHMENT Elias W. Blewett, Forty Fort, Pa'. Application December 28, 1942, Serial No. 470,374

1 Claim.

The present invention relates to new and useful improvements in darning and embroidering attachments for sewing machines and has for one of its important objects to provide, in a manner as hereinafter set forth, a device of this character which is adapted to be expeditiously mounted for operation on the machine after the usual presser foot has been removed therefrom, without the necessity of altering said machine structurally in any way.

Another very important object of the invention is to provide, in an attachment of the aforementioned character comprising a spring pressed foot, novel guide means for slidably supporting said foot.

Other objects of the invention are to provide a sewing machine attachment of the character described which will be comparatively simple in construction, strong, durable, highly eflicient, reliable and quiet in operation, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specication, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure l is a view in side elevation of a darning and embroidering attachment constructed in accordance with the present invention.

Figure 2 is a view in front elevation of the device.

Figure 3 is a top plan view.

Figure 4 is a bottom plan View of the attachment.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises an attaching bracket which is designated generally by reference numeral I, said bracket being formed from a single length of suitable sheet metal.

The bracket I includes a vertical, elongated, upwardly tapering plate 2 which terminates, at its upper end, in a forwardly projecting end portion constituting an apertured guide 3.

Projecting rearwardly from the lower end of the plate 2, substantially at right angles to said plate, is a ange 4. The flange 4 is folded on itself, as at 5, and terminates in a forwardly projecting end portion constituting a guideG having a transverse slot 'I therein which is vertically aligned with the aperture in the guide 3. The flange 4, together with the portion 5 thereof, has extending thereinto from its free end a longitudinal slot 8 for the reception of the usual presser bar of the sewing machine, after the conventional foot has been removed therefrom.

Mounted for vertical movement on the bracket I is a metallic rod 9 of circular cross section. The rod 9 extends slidably through the aperture in the upper guide 3 and has its upper end portion mutilated in a manner to provide a stop I0. On the lower end of the rod 9 is a at metallic plate I I which extends slidably through the transverse slot 1 in the lower guide 6. Projecting forwardly from the lower end of the plate II is a substantially cup-shaped foot I2 having a centrally located circular opening I3 therein which accom-- modates the needle of the sewing machine.

A coil spring I4 is mounted on the rod 9. The upper end of the coil spring I4 is engaged beneath the guide 3. The lower end of the coil spring I4 is engaged with the shoulders provided by the upper end of the plate II for yieldingly urging the presser foot I2 downwardly on the work.

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. Briefly, the usual presser foot is removed from the sewing machine and the bracket I is mounted in its place. The machine is then actuated and the material is manipulated beneath the presser foot I2 in an obvious manner. The shape of the foot I2 facilitates moving the work in any direction.

It is believed that the many advantages of a sewing machine attachment constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be restorted to which will fall within the scope of the invention as claimed.

Having described the invention, what is claimed as new is:

A darning and embroidering attachment of the character described for sewing machines comprising, a bracket for mounting on the presser bar of a sewing machine, said bracket being formed from a single length of sheet metal and including vertically spaced, forwardly projecting upper and lower guides, the lower guide having a transverse slot therein, a rod slidable in the upper guide, a plate on the lower end of the rod slidable in the slot in the lower guide and substantially wider than said rod to form shoulders at opposite sides of said rod, a presser foot projecting forwardly from the lower end of the plate, a coil spring under tension on the rod between the upper guide and said shoulders for yieldingly urging the foot downwardly, and a stop on the upper end of the rod engageable with the upper guide and limiting sliding of said rod downwardly.
