RUSSEL G. WOODWARD, OF WAUKEGAN, ILLINOIS, ASSIGNOR TO UNIONSPECIAL SEWING MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

SEWING AND RUFFLING MACHINE.

Specification of Letters Patent.

Patented June 23, 1908 Application filed July 14:, 1903. Serial No. 165,490.

To all whom it may concern:

Be it known that I, RUssEL G. W001)- 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 and Rufliing Machines, of which the followingis a description, 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 rufliing machines, the particu lar object being to provide a sewing and rufliing machine in which the sewing apparatus involves a zig zag stitch-forming mechanism, and is combined with a' rufller.

The purpose for which the present machine has been especially devised is for forming a seam such as illustrated in my Patent No. 718,960, that is, in brief, for providing a fabric with a series of rufiies and securing the ruffles by stitches composed of parallel rows of loops, the loops of one row passing through the bases of the ruffies, and the loops of the other row passing through beyond the edge of the ruffles, the connecting threads lying along side the bases of the ruffles, whereby the tops of the ruffles are left free and open, and the stitches are substantially hidden, only the points of the triangular stitches showing where they pass over the edge of the ruffle. If this ruffle is secured to a body fabric, as shown in said patent, the points of the stitches will show in the body fabric; otherwise, they will project simply beyond the edge of the ruffled fabric. It will be understood, however, that I do not wish to be limited to the particular mechanism shown for making a cross stitch, for other stitch forming mechanism of'this character may be combined with devices, whereby the fabric may be ruffled, the ruflie secured by suitable stitches which do not pass through the tops of the rufiies, but in which the cross stitches or threads extend around the bases of the ruflies formed, one line of stitching being within the fabric and the other outside the edge thereof and passing through a body fabric or both being within the edge of the ruffled fabric.

In providing a machine adapted to make the seam above referred to, a number of features of importance have been developed, among which may be mentioned the provision of mechanism for actuating the rufliing blade against the fabric, only every other stitch, so that the fabric will not rufi'le when the stitch outside of the fabric is being taken. It has also been found desirable to provide a device for catching hold of the ruflie, which has been pressed down by the presser foot, ahead of the stitch-forming mechanism, and drawing it up into vertical position, so that the stitch which is taken inside the edge will not pass through the top of the rufiie being afterward pressed down again by the action of the rear part of the presser foot.

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

So far as the general structure of the machine is concerned, it is of the Union Special overseaming machine type, in which the needle bar is supported in a laterally swinging frame, and there are connections between the frame and the driving shaft, for imparting lateral vibration to the needle. The particular means for vibrating the needle herein shown, are similar to those shown in an older type of Union Special overseaming machine, which has practically been superseded by the type of mechanism shown in the application for Letters Patent filed the 24th day of May, 1900, by Charles G. Kramer, and serially numbered 17,791, but this is only shown by way of illustration. The drawings illustrate the particular mechanism illustrated in an application for patent filed by Lansing Onderdonk, No. 676,432, filed April 4, 1898.

The particular rufliing mechanism illustrated in this application is the same as that illustrated in my Patent No. 706,484, dated August 5th, 1902, except for the provision of the means above referred to for throwing the ruffler blade out at every other stitch.

The invention is illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of a sewing machine embodying the invention Fig. 2 is.

an end view of the same Fig. 3 is a perspective view of the machine, with all the parts removed except the presser foot, the ruflier, the mechanism for throwing the rufiier out of action at every other stitch, and the mechanism for holding the ruffle in a vertical osition while the needle is taking the stitc 1 on the inside of the edge of the ruffled fabric; Fig. 4 is a similar view, the parts being shown in a different position from that in Fig. 3; Fig. 5 is a ruffling mechanism, and ru e-holding mechanism, detached; Figs. 6 and 7 are detail views, showing the position of the parts in the formation of the inside and outside stitches Fig. 8 is a front view of the camfor operating the ruffler-raising device, and for operating the ruffle-holding finger; Fig. 9 is a detail sectional end view of the pivot support for the bar which operates the rufile-holding finger. In these drawings, A represents the base of the machine; B, the goose neck or overhanging arm; C the needle lever, which imparts vertical reciprocating movement to the needle bar a. v

D represents the swinging frame, which supports the needle bar a, said swinging frame having lateral vibration imparted to it by means of the pitman connections I) to the frame 0 pivoted on the sewing machine standard, and which has a downwardly projecting stud d, carrying on its lower end a roller 0, which travels in the cam groove f, which is formed with a gear wheel g, the hub of which is sleeved on a stud on the machine frame, said gear wheel 9 being in mesh with a gear wheel H on the driving shaft E of the machine.

The numeral 23 represents a rock shaft journaled in suitable bearings on the bed plate. On the outer end of the rock shaft 23 is a collar 25 supporting an arm 26, which carries the ruffling blade 27 pivoted thereto, and held down to its work by the spring 28, motion being imparted to the rock shaft to cause the ruffler blade to operate in the manner set forth in Patent 706,484, above referred to.

All the parts heretofore referred to are of the usual well known construction, and need not be more particularly described.

I will now describe the mechanism for imparting to the ruffler blade an upward. movement to cause it to fail of its rufiiing action every other stitch; that is, to prevent its ruffling while the needle is making the stitch outside the fabric.

The gear and cam wheel 9, has at its outer edge, a cam shaped periphery 7L, adapted to engage a lug or projection i, secured to the end of the shaft 76, journaled in lugs l, on the bracket plate m, secured on the work plate of the machine. At the opposite end the shaft It has a projecting finger n, which engages the under side of the pin 0, secured to the ruffler blade support. When the high part of the cam h, reaches the projection i, it depresses the same, rocks the shaft is, and

lan view of the,

raises the ruffler blade 27 from the work, thus causing in each revolution of the main shaft, a reciprocation of the ruffler blade to take place without ruffling the fabric. The parts are so timed, that this rise of the rufller blade begins while the needle is descending to make the stitch outside the ruffled fabric 1, and is held in its raised position while the needle moves upwardly and laterally and into the goods and until it begins to rise, the ruffiing taking place while the needle is receding from its position in the goods.

It will be understood that so far as this feature of the invention is concerned, the timing may be changed, or the intervals of ru-ffling and idleness may be varied, Without departing from the spirit of my invention.

P represents the presser foot of the machine, supported on the presser bar P, in the usual way. The action of a presser foot upon the ruffles is, of course, to press them down, and usually the stitches pass through the ruffles, as it is desirable in making the seam set forth that the tops of the ruffles be left free and 0 en, and the inner row of stitches pass on y through the bases of the ruffles, and that the connecting threads to the outer row lie alongside the bases so that they will besubstantially covered up by the rufiies, the presser foot has an open space p, in which the needle reciprocates, and a movable finger or blade g, on the end of the arm q, is provided for seizing a ruffle and holding it vertically out of the path of the needle while the stitch in the rufiied goods is being made. The arm g is fixed to the end of a lever 0", which is pivoted to swing vertically on the pin secured to the block 15, having a vertical pivot u, on the end of the bracket pla-te'v, secured to the work plate of the machine. At its op osite end the lever r, is formed with a IBCfllCGCl head carrying a ball w, which fits in a socket formed on a plate :1; adjustable by slot and set screw y, z, in a groove 2, formed in the plate 3, fitting the inner periphery of the cam ring h, being held therein by the wedging screw 4.

In order to give the movements desired to the lever r, thesocket in which the ball to fits must be off the center, and the time of movestitched while the needle is shifting to the right (looking toward the machine), and while it is moving down on the outside the ruffled goods, the finger or blade g, moves down between the ruffle which is next to be stitched, and the one which is in front of it, when the needle begins to rise, the blade q, moves to the rear of the machine, raising the ruffle to vertical position and holding it there until the needle passes into the base of the ruflie, when it begins to rise, and then moves forward while the needle is in the ruffled goods, and while the blade 27 is forming another ruflie. It will be seen that while the ruflier is making its idle forward movement, the blade g is straightening up the ruflie. After the sewing the ruflles are pressed down by the rear portion of the presser foot. A wire guide 30, for the fabric upon which a fold is turned, is provided, although any suitable folding guide may be provided;

Various modifications and changes may be made in the invention, without departing from the spirit of the same, and it will be understood I do not wish to be limited to the particular stitch forming mechanism herein shown, as other cross stitch mechanisms may be used combined with the ruffling device, acting in such manner as to make a ruffled seam in which the cross stitches lie alongside the bases of the rufiles and the holding stitches are not deposited in the ruffles themselves, but in such position as to hold them permanently, but leaving the tops free and 0 en.
