NATHAN E. I-IANSON, OF NEW YORK, N. Y., ASSIGNOR TO UNION SPECIAL MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

RUFFLING AND SEWING MACHINE.

riesgos.

T all whom it may concern Be it known that I, NATHAN E. HANsoN, a citizen of the United States, residing at New York, in the county of New York, Sta-te of New York, have invented certain new and useful Improvements in Ruiiiing and Sewing Machines, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of reference marked thereon.

This invention relates to new and useful improvements in sewing machines, and more especially to machines for rufling and sewing, the object of the invention being to provide a machine wherein ruffles of all sizes from the largest to the shadow rufiling may be made, or the ruttling action may be stopped entirely, without stopping the action of the stitch-forming mechanism.

A further object of the invention is to provide a machine of the above character with guides for guiding various pieces of material, so that they may be secured to the strip being ruflled.

Further objects of the invention will in part be obvious, and will in part be hereinafter more fully described.

The invention consists in the parts, improvements and arrangements hereinafter shown and described.

In the drawings which show by way of illustration only one embodiment of the invention, Figure 1 is a front view of a sewing machine embodying my invention; the knee shift being omitted from this view; Fig. 2 is a detail view of the mechanism for operating the rutfler shaft from the main shaft of the machine; Fig. 3 is a similar view from the opposite side, showing also the mechanism for adjusting the throw of the rufliing mechanism; Fig. 4 is a detail view, showing the knee shift and its connection with the adjusting device for the ruffling mechanism; Fig. 5 is a detail view from the end of the machine, showing the needles, the presser foot, the guides for the fabric and the ruffler; Fig. 6 is a detail view showing the operation of the ruffler in connection with the presser foot; and Fig. 7 is a cross section of l a seam made on one form of my invention.

Fig. 8 is a sectional view through the segment plate showing the stop nut and the adjustable bolt.

The machine herein shown by way of 55 illustration, is similar in many respects to Specification of Letters Patent. Fatal/ted Jun@ 22, 1915 Application mea my s, 190s.

serial No. 442,529.

that shown and described in the patent to Russel G. Woodward, No. 706,484, granted August 5th, 1902. It will be obvious, however, that from certain aspects the invention is not limited to this particular type of machine, but may be embodied in various types of ruliiing and sewing machines.

The bed plate 1 has rising therefrom an overhanging arm 2, carrying a needle head 3 at its forward end, in which reciprocates a needle bar 4, carrying needles 5, 5, at its lower end. Said needle bar is reciprocated by the needle lever 6, through the link 7, from the main shaft 8 in the well known manner.

The ruiiiing blade 9 is secured to a head 10, by suitable screws. Said ruliiing head 10 is pivoted at 11 to the supporting arm 12, which is carried by the rock shaft 13 mounted in suitable bearings carried by the bed plate 1. The shaft 13 at its rear end is provided with an arm 13, which is connected to the auxiliary shaft 132, carrying an arm 14, to which is pivoted a link 15 in a manner shown in Patent 706,484, above referred to. rlhe forward end of the link 15 is provided with a bolt 16, carrying a pivot block, running in a curved slot 17, in the segment plate 18, pivoted at 18 to a lug carried by the frame of the machine. The segment plate 18 is vibrated by means of an eccentric 19 carried by the main shaft 8, through an eccentric strap 20, which is pivoted at 21 to said segment plate.

The mechanism above described is sub stantially the same as that shown in the patent to Woodward above referred to.

By adjusting the bolt 16 in the slot 17, toward and from the pivot point 18, the throw of the ruffler blade may be increased or decreased, and if the pivot bolt 16 is brought so as to coincide with the axis of the pivotal connection 18, then no vibration whatever will be imparted through the link 15, and the ruffler will be thrown out of action. The slot 17 is preferably curved concentrically about the pivotal connection between the link 15 and the arm 14 when the ruflling blade is at its eXtreme forward position. This construction will afford means for holding the ruilling member the same distance from the needle at the forward end of its stroke during all its adjustments.

As a means for adjusting the throw of the ruiling blade, I have provided a rock shaft 22 which carries an arm 23, to which is pivoted a link 24. rlhe opposite end of the link 24 is pivoted to the connecting bolt 16 The shaft 22 also is carried by suitable bearings formed in the bed plate 1 of the machine, and at its rear end is provided with an ar1n25. A spring 26 is connectedv at one end to an eye 27, carried by the arm 25, and at its other end to a stud 28, carried by the head of the machine. Said spring 26 normally tends to hold the arm 25 raised, and the arm 23 lowered, which will hold the pivot bolt 16 at the lower end of the slot 17 in the segment plate'V 18. An adjustable screw 29 is carried by a lug 30, supported by the bed plate of the machine, and extends into the path of thev arm 25', so as to'limit its upward movement. A stop nut 31 serves to lock the adjustable screw 29i in various positions. A stop bolt 32 is mounted in the slot 17, and may be readily adjusted up and down in the slot to any position Adesired by loosening the nut carried thereby. This stop bolt serves to limit the upward movement of the pivot bolt 16. As a means for shifting the arm 25, I have shown herein a knee shift 33, which is pivoted at 34 to a suitable bracket 35 carried by the machine stand. A rod 36 is connected at 37 to the lever 25, and at 38 to the knee shift 33.

In the operation of my device, the stop bolt 32 is so positioned in the slot 17, that when the bolt 16 is thrown against said stop bolt the largest size ruffle desired will be made. The stop screw 29 is properly set so as to determine the smallest size ruffle desired. The operator then by manipulating the knee shift 33 may, without stopping the machine, readily throw the link 15 so as to make the largest size ruffle or the smallest size ruffle, or any intermediate size ruie desired. lVhen it is desired to stitch a certain distance without any ruliiing whatever, the screw 29 is then so positioned that the bolt 16 may be thrown down over the axis of the pivot 18. The presser foot 39 has a stripper blade 40, secured thereto by suitable screws, and said stripper blade is located so as to extend down under the front portion of the presser foot. The ruiiiing blade 9, as above noted, is pivotally connected with the arm. 12, and a spring 41 engaging the under side of the ruffling blade see Figs. 1 and 6, normally tends to hold the rufliing blade thrown up against the stripper blade 40. The strip of fabric A to be rufiied, is led through the guide 42 carried by an arm 43, rigidly secured to a block 44, attached to the bed plate of the machine. Said guide 42 is so disposed that the strip of fabric A passes between the stripper blade 40 and the ruffling blade 9. Thevib'rations of the rufling blade carry the fabric forward, forming the ruffles against the under side of the stripperblade, which are held thereby in the usual manner. I have also shown a fabric guide 46, for guiding a piece of fabric B. Said guide 46 is so located as to carry the fabric B underneath the ruflied strip, and is so constructed as to fold over the edge of the fabric B on to the upper face of said fabric. l have also shown a tape guide 47, which is formed integral with the presser foot, and leads a strip of tape C down through a slot in the presser foot in front of the stitching point. Said tape guide 47 is provided with means for folding the edges of the tape uuderneath, and is located so that said tape is led to the stitching mechanism, and a line of stitching passed therethrough adjacent each edge of the tape. This tape is secured to the fabrics A and B so as to cover the raw edges of said fabrics.

It will be obvious from certain aspects of my invention, that various forms of fabric guides may be used in connection with the ruiiling mechanism herein shown and described, and that, therefore, the present disclosure is only one illustration of the capabilities of operation of my device.

The sewing machine is, of course, provided with the usual feeding mechanism and the mechanism for operating the rufller is so timed when forming ruiiles as to give to the rufliing blade a differential movement rela tive to the movement of the main feed. It will be obvious that instead of a ruiiling blade technically known as such, other rufing members may be substituted therefor. If the rufiiing mechanism herein shown, operate upon elastic fabric such as knit goods, it is obvious that the ruiiling action may be adjusted so that the elastic material will gather only sufficient to overcome the tendency to stretch, thus stitching said elastic fabric evenly and smoothly to another material.
