Letters Patent No. 100,161,

dated February 22, 1870.

IMPROVEMENT IN RUF-ILING- ATTACHMENT FOR SEWING-MACHINE.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, ARTHUR M. Lnsnrn, of Ohicago, in the county of Cook, and State of Illinois, have invented a new and improved Rufliing-Attachment for Sewing-ll/Iachine; and I do hereby declare the following to be afull,clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had'to the accompanying lrawingsforming part of this specification, in which- Figure 1 is a perspective View of my .improved ruffler attached to the bed-plate of a sewing-machine; and

Figure 2, a pers from the machine.

Similar letters of reference indicate corresponding parts in the several figures of the drawings.

My invention has for its object to improve the construction ofrufliers for,sewing-machines, whereby the same are rendered more etficient in their operation.

My invention consists in a rufiier composed of two elastic plates, made adjustable with -relation to the resser-foot and feed-surface, and provided with a curved slot, so that, when adjusted about its confining screw for the purpose of regulating the fullness of the gathersor ruffles, the slot shall always be in range of the needle.

It consists further in an adjustable locking-device for securing the ruflier in position uponthe machine with reference to the feed-surface.

In accompanying drawings- A is the top or main portion of the rnttler, composed of a thin elastic metal plate, attached at one end to the bed-plate B ofa sewing-machine by means of the gauge-screw 0.

Its free end extends forward beneath the presseribot D of the machine .and over the feed surface of the latter.

This end of the main plate A is provided with two slots ab, the former serving to guide the cloth to be ruflied and its hand, and the latter arranged at an angle to the former, permitting the passage of the pective view of the same detached To the under surface of this plate is attached by means of a rivet or the screw andnut 0, one end of the second and smaller elastic plate E, shown in dotted lines, fig. 2, whose enlarged free end bears against the under surface of the plate A, between the slots a b. It is prevented from displacement by means of the stud d extending through the top plate, as shown.

The cloth 1 to be rutfled is placed under the plate Enpon the teed-surface of the machine, with its edge The band G, to which the cloth is sewed to forrn the ruflie, also passes through the slot a above the plate A, and between such plate and the under plate E.

By this means the presser-foot, instead of bearing directly upon the hand, rests upon the plate A, while the enlarged outer end of this plate and the plate E, distribute the pressure over a large surface of the band and cloth, and facilitate their easy passage through the machine.

The needle I passes throu cloth to the band.

It is often necessary or-desirable to change the rattling to make the same more or less full. This is accomplished in the following manner:

\Vhen. it is desired to gather the rufiie very full, the rufiier is moved in a direction opposite the feed of the machine, or toward the operator, so that but a small surface of the cloth beneath the bottom plate E, and in rear of the needle is exposed to the action of the feed-surface after the cloth has been stitched to the band.

This feeds the cloth and band slowly, and permits a larger accumulation of gathers in front of the needie before stitching. v

\Vhen the ruffler is moved in the opposite direction, so that the feed shall act upon a larger surface of cloth in rear of the needle, and a smaller surface in front of the same, the cloth and band pass through the ruflier with greater speed after-having been stitched together, and there is less accumulation of gathered cloth in front of the needle.

From this description it will be seen that-the fullness of the rufiiing depends upon the amount of cloth acted upon or gathered by the teed-surface in front of the needle. I

The opening bin the plate A is curved and elongh the slot 1) to'unite the gated to permit the passage of the needle when the rufiierisadjusted with relation to the feed-surface. Its' edges are also graduated to indicate the degree of rutflin g desired.

In order to prevent the displacement of the rufilcr with reference to the feed-surface and PICSSBT-fOOt, and at the same time permit the adjustment of the ruffler, I have provided a lever, H, pivoted centrally .to the bolt 0 or rivet which unites the plates A E, and

extending atone end to the presser-fbot, at which.

point it is provided with a pin or stud, 71-.

Its opposite end is formed with a slot, t, through which the adjusting screwO passesto clamp said lever in position.

\Vhen the rutller is adjusted to form a ruflie of the desired fullness, the lever II is also adjusted so that the pin it shall bear against the side or end of the.- presser-foot, and thus hold the rutfier in-p'osition;

My improved rufiicr is easily constructed, and per forms its work in the most thorough and satisfactory manner.

Having thus described my invention,

What I claim as new,and desire to secure by Letters Patent, is-- 1. The rufiler for sewing-machines, consisting of the two elastic plat-es A E, constructed as described, the former being provided with the curved slot to admit of the movement of the ruffler about its holding screw, in order to adjust the position of the plates,

with relation to the feed and foot, to regulate the fullness of the gathers or rnffles.

2. An adjustable locking-device, in combination with a rufflor for sewing-machines, which shall bear against the presser-foot and hold the miller in position with reference to the feed-surface, substantially as described.

\Vitnesses: ARTHUR M. LESLIE.
