SEWING-MACHINE PRESSER-FOOT.

SPECIFICATION forming part of Letters Patent No. 722,441, dated March 10,1903. Application fil ed September 1, 1899. Serial No. 729,193. (No model.)

To a whom it may concern.-

Be it known that I, RUssEL G. WooDWARD, a citizen of the United States, residing at Waukegan, in the county of Lake, State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a description, reference being had to the accompanying drawings and to the letters and figures of refer- IO ence marked thereon.

My invention relates to an improvement in presser-feet for sewing-machines, and has been designed especially for use on what is known as the Union Special Yoke Rufliing 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 20 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 connection with a ma- 2 5 chine 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 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 a high ridge of cloth is reached the foot will tilt when the projection strikes the toe of the foot, but will bind beneath the body of the part. 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 arrangeo ment of feet in which the part bearing on the ridge 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 having a part which both tilts and has a bodily-vertical movement.

It also consists of a presser-foot having a part which is pivoted to the main part, said part and its pivot being movable up and down.

Finally it consists in the matters hereinafter described, and referred to into the appended claim.

The invention is illustrated in the accompanying drawings, in which- Figure '1 is a perspective view of a portion of a Union Special Yoke Ruffling Machine, showing myinvention applied thereto. Fig. 2 is a perspective view of the presser-foot. Fig. 3 is a vertical section of the presser-foot in a plane including the line 1 1 of Fig. 2. Fig.4 is a cross-section on line 2 2, Fig. 3.

In the drawings, A represents the bed-plate,

B the gooseneck, C the needle-lever, D the needle-bar, E the presser-bar, and F as a Whole the mechanism supporting and actuating the ruffler-blade, all these parts being similar in construction and operation to corresponding parts shown and described in the application above referred to.

The presser-foot to which especially the present invention relates is shown with its shank 1 adapted to be clamped around the lower end of the presser-bar E. It is provided with the integral rigid part 2, adapted to bear on that portion of the fabric which is to be ruffled and united to the other portions of the fabric. The other portion 3 of the presserfoot has the upwardly-extending lugs 44, embracing the part 5, formed with the shank of the presser-foot and pivoted thereto by means of the pivot-pin 6. The pivoted portion 3 of the foot is provided with openings for the passage of the needles and bears on the portion of the fabric outside the line of ruffling and by reason of the fact that it is pivoted will tilt when an extra thickness of goods, such as a seam, passes under it. To permit of the part 3 also moving bodily as well as tilting for the purpose referred to in a former part of this specification, this part 5 where the pivot-pin6 goes through it is vertically slotted, so that as the part 3' is pressed up by the action of the fabric beneath it the pivotpin will slide in the slot 7 Normally the part 3 5 is kept pressed down to its work by means of the spring 8, secured to the shank of the foot by the screw 9, the free end of the spring resting upon the cross-bar 10, extending between the lugs 4 4.

walls embracing the rigid vertical part and provided with a pivotpin passing through said vertical embracing walls and loosely fittint, the slot, with means for keeping said second portion normally depressed upon the fabric, substantially as described.

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

RUSSEL G. WOODWARD.
