UNITED STATES PATENT OFFICE.

RUSSEL GREEN \VOODWARD, OF WVAUKEGAN, ILLINOIS, ASSIGNOR TO THE UNION SPECIAL SEWING MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

RUFFLING AND SEWING MACHINE.

SPECIFICATION forming part of Letters PatentNo. 706,484, dated August 5, 1902. Application filed May 17, 1898. Serial Nofifi 80,971. (No model.)

Illinois, have invented certain new and useful Improvements in Ruflling and Sewing Ma'- chines, of which the following is a description, reference being had to the accompany- 1 ing drawings and to the figures of reference marked thereon.

My invention relates to an improvement in sewing-machines, and especially to machines for ruiiiing and sewing, the object beingto provide a machine wherein by mere adjustment ruffles of all sizes from the largest to the shadow ruiiling may be successfully made.

The invention consists, primarily, of improved means for operating the rufiler-blade and providing for the necessary adjustments in a simpleand efiective manner, while, further, the invention consists in an improved arrangement and relationship of the rufflerblade, feed presser-foot, and stripper-blade, whereby all danger of the ruffler-blade dislodging or drawing back the goods or pulling out the gather in its backward movement is 1 avoided, the action being further aided by the peculiar construction of the presser-foot.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a sewing-machine embodying the invention, aportionof the bed-plate being removed to show the parts for operating the rufller. Fig. 2 is an enlarged view, partly in section, showing the manner of effecting the adjustment to varythe length of the ruffle. Fig. 3 is an end view ofjthe ma chine, showing the relation of theparts as the feed is rising,the presser-foot,too,is rising, and the ruffler-ismoving forward beneath the end of the presser-footr Fig. his a similar view showing the parts as the feed isfalh ing, the foot is falling, and the ruffler-blade is backing out Fig. 5 is a detail view of the presser-foot. Fig. (5 is a perspective view of the operating parts,and Fig. 7 is an end view of the same.

Inthe drawings the machine illustrated is the well-known Union Special single-needle double-chain-stitch machine, and the parts .24: and 25 on the bracket 11.

thereof need no explanation, the feeding mechanism, looper movement,and other parts of the sewing organization being of that familiar type.

The. main or driving shaft of the machine is represented by the. numeral 1, and in suitable position thereon is-an eccentric 2, cmbraced by a strap 3 on the connecting-rod 4, as clearly shown in Fig. 7, which connectingrod at its outer end is sleeved on a stud 5, secured to a projecting lug 6 on the curved arm 7, which has a sidewiserprojecting collar 8 on its lower end secured on the shaft or pin 9, journaled in the lug 10 on the l bracket 11, formed with the bed of the machine. The arm 7 has in the face toward the front end of the machine a T-slot 12,in which fits and is guided the squared head 13 of a stud or bolt 14, on which is sleeved the collar or head 15 on the end of the arm 16, which at the opposite end is sleeved on the pin or shaft 17, passing through and secured to the upper end of the link 18, pivoted to the bracket 19, sunk into the bed of the machine. It will be seen that the pivoted link, with the shaft 17, forms a rocking frame, the arm 20, sleeved on said shaft 17, beingat its outer end sleeved on the rod or stud 21, secured to the upper end of the arm 22, clamped at its lower end on the rockshaft 23, which rock-shaft is journaled in lugs On the outer end of the rock-shaft is secured one end of the arm26, which carries the ruffling-blade 27, pivoted thereto and held down to its work by the'spring 28 in a manner well known. The ruiiier-blade has a slot 29 to allow of the passage of the needle, the points of the ruffler-bl'ade on either side passing beyond the plane of the needle. It will be seen that by this arrangement of the two independent rockframes-the link operated from oneand transmitting motion tothe otherthe parts can be so timed, by placing the eccentric properly on the driving-shaft, that the gathering of the goods is accomplished .while the presser-foot is firmly clamping the goods against the throat-plate, so that whenthe needle is near its highest point the rufller is receding and the feed is operating, the feed beginning to lower and letting the presser-foot down on the goods to hold the latter just as the ruflierfoot and throat-plate, the ruffler moving back and forward again while the presser-foot is down. I

To prevent any danger of dislodgment or shifting of the goods while the rufiier is receding, I provide the presser-foot with agroove 30 to receive the ruffled portion and a beveled part 31, which cooperate with the stripper-plate 32, the action being such and the parts being timed so that as the feeddrops and the presser-foot falls the fabric on the end of the ruffler-blade will be clamped between the end of the foot and the said stripper-plate, and thus the blade can back out of the ruffie, leaving the latter firmly held, so as to be caught by the stitches. By this arrangement a ruflie of minimum width may be sewed on this machine. To provide for proper setting of the machine for different widths of ruffles or gathers, the arm 7 has on its outer face an index, while the head or collar 15, pivoted on the bolt 14, the squared head of which bolt 14 is adjustable up and down in the slot 12 and secured in position by nut 33, is provided with a piece or plate 34, carrying a pointer 35 to register with the notches on the index.

For convenience of the operator, to be used when a Very slight ruffie is to be made and when the head 15 is near the lower limit of the slot 12, an extension 38 is pivoted on the head 15, which extension may be used as a pointer.

The rock-shaft 23 is provided with a V- shaped slot milled into its outer end, and the part 26, which is clamped around said rock shaft, is provided with an opening for a setscrew, which passes through the end of said arm into the V-shaped slot, therebyinsuring always the proper setting of the arm 26 on the rock-shaft.

Various minor modifications and changes in the construction of the apparatus may be made Without departing from the spirit of my invention.

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