RUSSEL G. WOODWARD, OF WAUKEGAN, ILLINOIS, ASSIGNOR T0 UNION SPECIAL MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

SEWING-MACHINE.

To all whom it may concern Be it known that I, RUssEL G. 001)- WARD, a citizen of the United States, residing at vVaukegan, in the county of Lake, State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, of which tion, reference being had to the accompanying drawing and to the letters and figures of reference marked thereon.

My invention relates to an improvement in sewing and ruliling machines, more especially adapted to the well known sewing and ruff-ling machine of the Union Special type, such as illustrated more particularly in Patent No. 655,143, ofJuly 31, 1900.

The object of the present invention is to provide a machine of the type referred to, in which the rufller and all the parts cooperating therewith, such as the folder, stripper blade, and edge guide, may all be thrown out of operation without disturbing the action of the stitch forming mechanism.

The invention has been especially designed for use in connection with skirt and pettieoat sewing and ruffling machines, in which a ruffle or series of ruflies, is to be secured to the body of the skirt, and it is desirable to throw out the rufliing apparatus, to enable the operator to end the seam where it be gan without the interference of the ruffling device, although, of course, the invention is applicable to any machine for sewing and rufliing tubular goods.

The invention consists in the matters hereinafter described and referred to, in the appended claims.

The invention is illustrated in the accompanying drawing, in which Figure 1, is a perspective view, of so much of a sewing and milling machine as is necessary to a complete understanding of my invention. Fig. 2, is a front end view. Fig. 3, is a skeleton perspective view of the mechanism for throwing out the ruflling attachment, the parts being shown disconnected from the machine head; F ig. 4 is a rear ele vation partly in section of the machine, the parts being broken away. Fig. 5 is a detail perspective view showing the relation of the presser foot to the stripper carrier and the ruffler. Fig. 6 is an elevation showing the rufller and manner of pivotally supporting the presser foot being re- Specification of Letters Patent.

the following is a descrip- Patented Jan. 5, 1915. Serial No. 151,826.

moved; Fig. 7 is a sectional view on line 77 of Fig. 6.

In these drawings, 1 represents the main shaft from which motion is imparted to the horizontal transverse bar 19, sliding in lugs 20, on the bracket 2, to which is secured a removable piece 3, having a groove 4, adapted to engage a feather 5, on the head of the machine. The supporting head 22 for the milling blade 27, is attached to the end of the transverse sliding bar 19, and to the bracket 2, is attached the stripper blade support, the folder support, and the edge guide support, these parts being of the usual construction. Motion is imparted to the rock shaft 15, in a manner similar to that shown in the patent above mentioned, except that the spring 50, always bears against the opposite side of the projection 49, from what it does in said patent, so as to always keep the lower end of lever 48, swung inwardly, and therefore, the rock shaft continuously vibrating. Motion is imparted to the sliding bar 19, and therefore, to the ruflier from the rock shaft by the following mechanism:

Upon the forward end of the rock shaft, is fixed a head 6, having two arms 7, extending downwardly therefrom, the opening be tween them being wider at the top, than at the bottom, the width of the space at the bottom being sufficient to receive snugly the arm. of lever 8, which has a link connection 18, with the sliding bar 19, and at its upper end is pivoted to the lower end of the fork 9, pivoted on a sleeve 10, surrounding the rock shaft and held in place by two collars 100 adjustably secured on the rock shaft. Upon the opposite or front side of the head of the machine, is pivoted at 11, upon an ad justable block 110 on the overhanging arm another arm or lever, 12, which is attached to the bracket 2. lVhen the arms or levers 8 and 12, are swung up on their pivots, the arm or lever 8, moves up out of the narrow space in the vibrating yoke formed by the arms 7, 7, and the wider part of said space in the yoke is sufficient to allow vibration of said yoke, without contact with the arm 8, thus when said arms are swung up on their pivots, the sliding of the arm 19 ceases, and therefore, the ruifler stops. The swinging of the arms or levers 8 and 12 on their pivots, and the consequent stopping of the ruffler, and throwing of all the parts which cooperate with the ruffier, out from the front of the needle, to enable the operator to join the edges of the tube, is accomplished in the machine herein shown, by having the rod 13, pivoted to the bracket 2, at its lower end and at its upper end, pivoted to the end of the presser foot lever 1 from the end of which connection is made by a chain to a foot treadle.

From the above, it will be apparent that the arm or lever 8 is in a sense a rocker arm which is pivotally supported at one end, while the other end thereof is connected to the rufiling blade. This rocker arm is, however, pivoted and when the outer end thereof is swung about the pivot through the aid of the treadle the rufiling blade is rendered ineffective. That is to say, this rocker arm serves as the means through which the vibrations of the rocking part 7 are imparted to the gathering or rufiling device and when said rocker arm is moved so as to be disconnected from said rocking part, then, of course, the vibrations of the gathering or ruflling blade cease.

Of course, other means may be devised for swinging the bracket 2 on its pivots, the pivots of the arms or levers 8 and 12, being practically the pivot of the bracket 2. The engagement of the groove 4, of bracket 2, with the feather 5, insures rigidity of the parts, while the ruflier is in action.

By means of the adjustment of the part 10 on the rock shaft, and the block 110, the rufiling attachment may be adjusted bodily to the right or left so as to swing on the arcs of the different circles. When it is desired to adjust the rufliing attachment to the right the block 3 is removed and the pivotal points moved to the right in the manner described. In order to raise the rufiling blade from the goods automatically as the presser foot is raised, I provide the arm 23 which supports the folder and stripper blade with a screw 112 which is located in the path of the presser foot 113. Vhen the presser foot is raised the foot engages said screw and swings the arm 23 upon its pivotal support. The lower end of the arm 23 contacts with the projection 111 carried by the ruffler head 22 and turns said head about its pivotal point and thus raises the rufiiing blade up from the stripper blade.

In practice the folder 25 and stripper blade 26, are supported by the bracket 2, through the depending arm 23. The edge guide support 24, is also hung from said bracket, in the usual way, while the ruffling blade is attached to the head 22. The folder is on the base piece 28, which is raised above the cloth plate 29 of the machine, to allow the body or fiounces of the skirt to pass beneath it. The piece to be rufl'led and sewed on to the flounces, has its edge folded and guided by the folder 25, and it is ruflied and fed to the stitch forming mechanism along with the tape passing through a guide preferably one on the presser foot. In sewing the ruflie on to the flounce of the skirt, when it is desired to sew the free ends of the ruiiled piece to the goods, or when for any other purpose continuous sewing and not rufi'ling is desired, the ruftler, stripper blade, folder and edge guide, are thrown bodily from in front of the needle and continuous sewing may take place.

Various minor modifications and changes in the construction and parts of this machine may be made, without departing from the spirit of my invention, and, of course, I do not wish to be limited in the use of this invention to the disconnection of a rufiling device alone from its operative connections,

for other tools or devices may be so manipulated as to be thrown out of action in a similar manner.

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