STRlP PER-PLATE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 690,812, dated January 7,1902.

Application filed'September 1, 1899- Serial No. 729,195. (No model.)

To all whom it may concern:

Be it known that I, RUSSEL G. WOODWARD,

a citizen of the United States,residing at Waukegamin the county of'Lake, State of Illinois,

have invented certain new and useful Improvements in Stripper-Plates for Ruffling- Machines, of which the following is a description, reference being bad to the accompanying drawings and t0 the letters of reference marked thereon.

My invention relates to an improvement in sewing-machines; and the especial object is to provide a stripper-plate for yoke-ruffling In achines which shall be supported from above I 5 and adapted to be raised as the presser-foot is raised.

In ruffling and sewing machines as ordinarily constructed the stripper-plate, which is used for the purpose of stripping the cloth 2o ofi the ruffling-teeth, is generally supported upon the bed-plate; but'I have found that where certainkinds of work are to be done on machines of this characteras,-for example, where the lower edge of a skirt is to be ruffledthis stripper-plate is in the way, and it is desirable to support it from above, just as the rnfiling-plate is supported, in order that the portions of the goods not ruffled may be passed beneath the presser-foot without beinglia-ble to be caught on the stripper-plate.

The invention therefore consist-s, primarily, in the sewing and ruffling machine having a stripper-plate attached to the frame of the machine and adapted to be lifted as the presser- 3 5 foot is lifted.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective View of so much of a Union Special Yoke-Ruffling Machine as is necessary to an understanding of my in-.

vention, and Fig. 2 is a detached view of the stripper-plate.

In the drawings the needle-lever A, gooseneck B, ruffling mechanism 0, cloth-plate D, needle-bar E, resser-bar F, presser-foot G, needles :1, and other parts are similar to those illustrated in my Patent No. 655,143, dated July 31, 1900.

it represents the stripper-platawhich is secured by suitable screws 1) to the transverse plate 0, formed on the lower end of the angular arm I. This arm I, at a point near its up per end, is provided with a projecting sleeve through which passes a screw cl, by which the I on the supporting-arm of the stripper-blade just above the presser-foot, so that when the presser-foot is raised it comes in contact with this lug or screwe and swings the arm I upwardly, thus raising the stripper-plate above the work.

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

1. In combination with'the ruffling mech anism of a sewing machine, a stripper-blade attached to the framework of the machine independent of the cloth -plate and ruffiing mechanism, and means for raising it above said cloth-plate; substantially as described.

2. In combination with the ruffiing mechanism of a sewing-machine, an arm pivotally 1 secured to the frame of the machine independent of the cloth-plate and above the same, a stripper-blade supported thereby, and

means for moving said supporting-arm on its pivot; substantially as described.

3. In a sewing-machine having a ruffiing mechanism and a presser-foot with means for raising and lowering the resser-foot, a strip-. per-blade, an arm supporting the same pivoted to the frame of the machine above the cloth-plate, and havinga projection extending into the path of movement of the presserfoot, whereby when the presser-foot is raised, it strikes the projection and raises the stripper-blade; substantially as described.

4. In a sewing-machine having a ruffling mechanism, and a presser-foot with-means for raising and lowering the presser-foot, a stripper-blade, a pivoted arm attached to the frame of the machine above the cloth-plate supporting the same, and having a projection offset from the vertical line of the pivotpoint, and extending into the path of movement of the presser-foot, whereby when the presser-foot is raised, it strikes the projection and swings the stripper-blade -snpporting arm on its pivot; substantially as described.

5. In a sewing-machine having a rurfling mechanism, and a presser-foot with means for raising and lowering the presser-foot, a stripper-Madman arm pivotally secured on the machine-frame and supporting the said stripper-blade, and having a projection ofiset from the vertical line of the pivot-point, and extending into the path of movement of the presser-foot, whereby when the presserfoot is raised, it strikes the projection and swings the stripper-blade-supporting arm on its pivot, said stripper-blade normally projecting beneath the forward end of the presserfoot, and held thereby in engagement with the work; substantially as described.

6. In combination with the ruffling mechanism of a sewing-machine, an arm pivotally attached to the lower part of the overhanging arm or head of the machine, a stripperblade supported thereby, and means operated by the movement of the presser-foot to swing said supporting-arm on its pivot; substantially as described.

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

RUSSEL Gr. VOODWARD.
