SEWING MACHINE ATTACHMENT.

SEWING-MACHINE ATTACHMENT.

To all whom it may concern:

Be it known that I, AARON Answer, a subject of the Emperor of Austria residing at New York, in the county and tate of New York, have invented certain new and useful Improvements in Sewing-MachineAt/tachments, of which the following is a specification. 4

This invention relates to sewing machine attachments, and has for its object to produce a combined presser foot and shirring attachment that can be easily and quickly attached to any ordinary sewing machine, and that will do eflicient work both as a presser foot and as a shirring device, and that will at the same time be simple and economical in manufacture, and easy to use.

These and other objects of my invention are described in the following specification and shown in the accompanying drawing, the particular features of novelty which constitute my invention being pointed out at the end hereof.

In the drawings similar letters and figures of reference refer to similar parts wherever they occur.

Figure 1 is a fragmental front elevational view of the head of a sewing machine and part of the base plate and feed, showing my invention applied thereto;

Fig. 2 is a similar view showing my device in position for shirring; and

Fig. 3 is a central vertical sectional view of my attachment taken alone.

I form my combined presser foot and shirrer in two principal parts, a main presser foot 10, having a shank lil formed to fit the end of the presser bar 12, provided with a set screw 13 for attaching it thereto; and a supplemental presser foot 14.

The main presser foot 10 is undercut to form a recess 15, the forward end of which extends somewhat past the needle hole 16, forming a recess or pocket adjacent to said needle hole.

The supplemental foot 14 is formed with an upper surface to fit the recess 15, and

. with a thumb notch 19 in the side of the foot Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed. November 3, 1917. Serial No. 200,149.

The supplemental foot 14 is pivotally attached to the main foot 10, as at22, at a point intermediate of the ends of the shank 20, so that said supplemental foot may be either turned (into engagement with the main foot 10, in which case its upper sur-v face fits the recess 15, and the operating surfaces 31, 32, of the two feet respectively, register with each other and form a substantially continuous presser foot, or the said supplemental foot may be turned-upon its pivot 22 outwardly and backwardly away from the main foot into the position shown in Fig. 2, so as to be out of the way of the operator and the-material operated upon.

A leaf spring 35 is secured to the face of the main presser foot shank 1-1, with which it is symmetrically shaped, in position to engage with the shank 20 of the supplemental foot 14, to hold said foot in its opened or closed positions until manually shifted from one to the other of said positions. Said leaf spring is formed with a substantially rectangular tongue 36, which passes through a slot formed in the front wall of the shank 11 of the main presser foot, in position to engage either one of the rectangular walls 40, 41, 42, of the shank 20 of the supplemental foot according to the position in which the latter is turned, this construction serving to hold the supplemental foot in adjusted positions as desired.

In operation, when my device is used as an ordinary presser foot, the supplemental foot is closed, as shown in Fig. 1, and the two feet then form, to all intents and purposes a single presser foot, which operates in all respects like an ordinary presser foot.

When it is desired to shir, the supplemental foot is moved outwardly and away from the main foot into the position shown in Fig. 2, and when in this position the feed of the machine will feed somewhat more than the usual amount of cloth, which will pass into the recess or pocket beneath the needle hole, thereby effecting a shirring as the needle stitches the gathered cloth together.

What I claim as new and desire to secure by Letters Patent is formed to engage said undercut face in one of its positions so that its operating surface will register with the operating surface of said main foot. 7 V

2. A sewing machine attachment comprising a main presser foot having an attaching shank and an undercut operating face, and a supplemental foot pivotally secured to the shank of said main foot, said supplemental foot'being adapted to be closed against said main foot to register therewith to oo-act as a presser foot, and to he turned away from said main foot when the latter is used for shirring, and means for holding said parts in adjusted positions.

3. A sewing machine attachment comprising a main presser foot having an attaching shank, an undercut operating face, amovable supplementary foot pivotally secured to said shank and adapted to beclosed into said undercut to co-act with said main foot as a presser foot, and to be turned away from said main foot at an angle to said shank when the main foot is used for shirring, and means for holding said supplementary foot in its adjusted positions.

4. A sewing machine attachment comprising a main presser foot having an attaching shank provided with rearwardly extending lugs, said foot having an unde'rcut operating face, an adjustable"supplementary foot having a shank pivotally attached to said lugs, and-a leaf.v spring secured to the inner face of the shank of said main foot having a tongue projecting through a slot formed in the last named shank to engage said supplementary foot to retain it in adjusted po- 7 surfaces to hold said supplementary foot in adjusted positions.

In testimony whereof,'I have signed my name to this specification in the presence of two subscribin'g'witnesses, this 8th day of August, 1.917.
