RUFFLING AND GATHERING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 349,279, dated Septeniberld, 1886.

Application filed April 17, i884. Serial No. 126,204. (No modrl.)

Toall whom it may concern.-

Be it known that I, ALLEN JOHNSTON, of Ottumwa, in the county of Wapello and State of Iowa, have invented a new and useful 1mprovement in Ruffiing or Gathering Attachments for Sewing-Machines, which improvement is fully set forth in the following specification.

This invention relates to that class of rufflers IO or gatherers in which the rufiling device, usually a reciprocating blade, is operated through two levers, one of which receives motion from a suitable moving part of the sewing-machine, and the other of which, receiving motion from the former, communicates it to the ruffiing device.

The invention consists in the new means or combination of devices for imparting motion to and for adjusting the stroke of the ruffling 2o device or blade.

The accompanying drawings represent an attachment constructed in accordance with the invention.

The device is shown on an enlarged scale.

Figures 1 and 2 are views in elevation from opposite sides, and Fig. 3 a,plan view. I

A is the ruffler-frame, which, as shown, is adapted to be secured to the bed-plate of the sewing-machine. A rattler-frame adapted to 0 be supported from the presser-bar or attached directly to the stationary arm of the machine could be used instead, being equally wellknown forms of ruflier-frames.

B is the auxiliary presser-foot,which extends under the usual presser-foot of the machine. In a foot-ruffler or ruffler adapted to be attach ed to the presser-bar of the sewing-machine. it would not be used.

0 is the separator, fastened at one end to an 0 arm of the ruffler-frame.

The ruffling device or blade D is operated by means of the two levers E F, which are pivoted at a to the upright plate b, making part of the ruffler-frame. The lever E is forked at the .5 outer end, and receives motion from the needle-bar or from other suitable part of the machine. The rufiier-blade is fastened to the projection or pin 0 at the lower part of the lever F.

The regulating device G, in the form of an elastic device or spring-arm, is pivoted at d to the lever F. The end 6 projects beyond the lever and forms a handle by which the lever can be turned. It is provided wit-h a lip, f, which engages the ratchet'or toothed surface 9, in virtue of the elasticity of the device, spring, or arm. By means of the handle 6 the device, arm, or spring can be withdrawn to disengage the lip f, and it can then be turned in either direction, to increase or diminish the stroke of the ruffling device or blade. When the needlebar rises and lifts the fork ed end of lever E, the said lever strikes the projection g on the lever F, and during the'rest of its ascent carries with it the lever'F. The ruffler-blade is thereby ad vanced to make a fold or gather in the fabric, which is inserted between it and the separator. WVhen the forked end of lever E is carried down, the projection h thereon strikes the adjustable device, arm, or spring G, and carries back the lever F and the ruffler-blade. By turning the said device or arm to theright in Fig. 1 the lever E makes contact with. the same later in its descent, and therefore carries back the ruffler-blade to a less distance. By turning the device or arm G to the left in Fig. 1 the contact will occur sooner,an d the ruffler-blade will be carried a greater distance. The stroke of the rufiler may thus be lengthened or shortened within the limits of the adjustment. VVhenever the device or arm is moved and the handle 0 released, the elasticity immedi ate] y makes the lips f engage the teeth of ratchet g and the parts are retained in position.

It is evident that modifications may be made in the details of construction without depart ing from the spirit of the invention, and that parts of the invention may be used separately.

I claim the new improvements described, to Wit:

1. A ruffling or gathering attachment composed of the following elements in combination, to wit: the ruffler-frame, the movable rufliing device 01" blade, the lever having a fork with onemember over or above the other in the outer end for engaging the needle-screw of the sew ing-inachine, the lever connected with the rut fier-blade and receiving positive motion in both directions from the former lever both said levers being arranged 011 the same side of the needle-hole as the said i'uffier-blade, and supported 011 said rufiier-frame so as to turn in the same direction, and the stroke regulating means for varyingthe amount of 10st motion between the ]evers, said means eomprisiug an elastic arm or spring and a, ratehet or serrated surface, \vhieh said arm or spring engages, substantially as deseribed.

2. In a rattling orgatheriug attaehment,and in combination with the rut'llingdeviee or blade and the two levers, one provided with a fork in the end to engage the ueedle-serew ot' the sewing-maehine, and both arranged on the same side ot the needle-hole as the said rullliug deviee orblade. the stroke-regulat ing meanseomprising a spring-arm fastened to one of said levers at the bottom, in proximity to the rut fling deviee or blade, and engaging with the ratehet or serrated surl'aee on the opposite side of the fulerum ot said lever, substantially as deseribed.
