RUSSEL G. WOODWARD, OF WAUKEGAN, ILLINOIS, ASSIGNOR TO THE UNION SPECIAL SEWING MACHINE COMPANY, OF CHICAGO, ILLINOIS,

A CORPORATION OF ILLINOIS.

SEWING-MACHINE PRESSER-FOOT.

SPECIFICATION forming part of Letters Patent N o. 722,550, dated March 10, 1903. Application filed May 21, 1900. Serial No.1'7,461. (No model.)

T all whom it may concern,.-

Beit known that I, RUSSEL G.WOODWARD', a citizen of the United States,residingat Waukegan, in the county of Lake, Stare of Illinois, have invented certain new and useful Improvements in Presser-Feet for Sewing-Machines, of which the following is a description, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

My invention relates to an improvement in presser-feetl for sewing-machines, and has been designed especially for use on what is known as the Union Special Yoke-Ruffling Sewing-Machine, upon which I made application for Letters Patent of the United States on the th day of July, 1898, Serial No.686,444.

It is the object of the present invention to provide a presser-foot having a part which partakes not only of a tilting movement, but which when a seam is passing under it will rise bodily to allow it to pass under. This is especially useful in a machine of the character described where the presser-foot is made in two parts, one part bearing on that portion of the fabric to be ruffled, While the other i bears on the thicknesses of goods not ruffled,

for if the presser-foot has only a tilting motion on its pivot when a heavy seam or high ridge of clothV is reached lthe foot will tilt when the projection strikes the'toe of the foot, but will bind beneath the body of the foot. So, also, if the foot has only a vertical bodily sliding movement when the projection strikes the toe there will be a bind which will last until such time as the ridge of the goods reaches the central point of the foot. By providing, however, an arrangement of foot in which the part bearing on the ridge or seam both tilts and lifts bodily the foot will first tilt as the ridge or seam strikes and will then gradually rise bodily as the ridge or seam passes under it.

The invention therefore consists of a presser-foot constructed as hereinafter described, and .referred to in the appended claims.

The invention is illustrated in the accompanying drawings, in which-- Figure 1 is a perspective view of my improved presser-foot. Fig. 2 is a vertical crossseotion; Fig. 3, a sectional side elevation of the same. Fig. 4 is a detail view of the upright vertical pin, and Fig. 5 is a detail View of the movable part of the presser-foot.

In the'drawings the presser-foot is shown as provided with a shank 1, adapted to be clamped around the lower end of the presserbar A. It has the integral rigid part 2, adapted to bear on a portion of the fabric. The other portion 3 of the presser-foot has the upwardly-eXtending lugs 44, embracing the part 5, which is formed with the shank of the presser-foot. This part 5 has an opening 6 through it, which opening is larger at the top than at the bottom, and through this passes a pin 7, provided with a ball portion 8, fitting within the opening, but too large to permit of withdrawal through the lower end of the opening, the latter being reduced and forming a seat 9 for the ball at its lower end, this pin at its lower end being fixed into the bottom of the part 3 of the presser-foot and being, therefore, rigid therewith. By this arrangement, therefore, the part 3 of the presser-foot may tilt upon the shank 5 as a pivot by means of the ball-joint, and bodily vertical movement is also permitted, as the pin can rise and fall in the vertical opening 6.

The part 3 is normally depressed by means of the spring 10 bearing on top of the pin 7.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A sewing-machine presser-foot, comprising a rigid portion, a vertical pin pivoted thereto and having vertical movement therein, and a foot portion adapted to bear on the fabric and rigidly fixed to said pin and means for normally depressing the foot portion upon the fabric; substantially as described.

2. A sewing-machine presser-foot, comprising a rigid portion having an opening therethrough, formed with a seat, a pin passing therethrough having a ball resting on said seat, and a foot portion xed to said pin and means for normally depressing the foot portion upon the fabric; substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
