RUFFLING ATTACHMENT FOR SEWING-MACHINESK SPECIFICATION forming part of Letters .lE'atent No. 284,628, dated September 11, 1883.

' Application filed November 22, 1881. (No model.)

To aZZ whom, it may concern/.-

Be it known that I, HARRY O. GoonRI om residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Im provement in Ruffling Attachments for Sewing-Machines, of which the following is a full description, reference being had to the accompanying drawings, in which Figure l is a top or plan view,- Fig. 2, a side elevation, showing the actuatinglink depressed aud the ruffling-blade drawn back; Fig. 3, a side elevation, showing the actuating link elevated and the ruffling-blade advanced; Fig. 4, a bottom or under side View.

This invention relates to rufflers or rufliing attachments for sewing-machines,and has for its objects to simplify the construction and perfect and improve the operation of the several parts composing the device or attachment, and to render the action of the ruffling-blade more certain and sure, and have its movements readily, accurately, and easily adjustable to give the required length of stroke, and have the blade so arranged and located with relation to its carrying and actuating mechanism that any failure to operate properly, either by reason of lost motion in any of the parts, irregularity of stroke of the ruffiing-blade, or improper time between the stroke of the ruffiing-blade and the movements of the needle, can be remedied and the device be made to work in a satisfactory manner in these re foot bar;

spects. These objects I accomplish by the novel construction and arrangement of devices hereinafterdescribed and claimed.

In the drawings, A represents the frame or support; B, the actuating-link; O, the sup-- port for the stationary cloth-retaining blade,- (1, the standard or upright of the frame; I), the socket for attaching the frame to the presserc, the opening for the passage of the presserdootbar; d, the base-plate of the frame; 6, the side piece or arm of the frame on which the slide or head moves; f, the slot in theside piece or arm; 9, the main slide or head secondary slide or head; 17, the slot in the slide or head 71 j, the ruffling-blade; 7c, the secondary stationary cloth-retaining blade; Z, the main cloth-retaining blade; m, the support for the forward end of the ruffling-blade; n 0 p q this frame or support is made from a single piece, bent or formed into shape to have a standard or vertical portion, a, a base or horizontal plate, (1, and a side piece orv arm, 6. The;

standard or upright a projects up from the forward end of the base or bottom plate, (I, and its upper end is provided with ahead or socket, b, in which is an opening, 0, for the passage of the end of the presser-foot bar. This standard or upright a is of the requisite length to be attached by its socket and have the under face of the base-plate (I rest over the material when the presser-foot bar is down, the same as an ordinary presser-foot, and when attached and properly adjusted the attachment is made secure by means of the set-screw a, passing through the socket b on one side, so that its end" will engage the face of the presserfoot bar.

The base or bottom plate, (1, stands at right angles, or nearly so, to the vertical standard or upright a, and projects out from such standard sufficientl y far to furnish a support ,for the side piece or arm, 6, and leave a clear space between the inner end of such arm and the standard. This base (Z is provided with an opening, 15, located at the proper point, for the passage of the needle, and to allow the needlebar to operate clearof the standard or upright a, and its rear portion is slightly elevated, so as to leave a clear space for the movements of the ruifling-blade and the passage of the cloth or material being ruffled.

The side piece or arm, 6, is located, as shown, at the extreme edge or side of the base (2, on the rear portion thereof, and has its forward or attached end bent or curved upward to bring the main portion or body in a higher The main por- 7 plane than that of the base. tion or body of this arm extends out suffir, set-screws; s, the slot in the free end of the perfect freedom of movement,

and keep the ing between the slide and arm,

' pivots of the actuating-link from coming in line and creating a strain on the parts.

The slide or head gis provided with a groove or recess on its outer side or face to receive the body of the arm 6, and is held inplace, so as to slide freely back and forth thereon, by means of the set-screw or pin, q, the shank. of which passes through a longitudinal groove,

f, in the body of the arm; or it may be held in place in some other suitable manner.

The slide or head his located on the inner side or face of the head or slide 9, and is held in place by means of a set screw or pin 1*, the shank of which passes through a slot, 1', in the head or slide h. This slot w is for the purpose of permitting the slide or head 9 to move in both directions, to a certain extent, without affecting the slide or head h, and when the limit of this independent movement of the head 9 is reached, the two heads 9 h will move together, the object being to give the proper length of stroke to the ruffling-blade. The distance that the slide or head 9 travels independently is regulated by a set-screw, o,

' located in the'end of the head h, the end of which can be made'to project a greater or less distance into the slot 43, so that in the backward movement of the head 9 the shank or body of the set-screw or pin 0" will strike the end of the set-screw o sooner or later in its movement and carry the slide or head h also back, and when the backward movement ceases the slide or head 9 will move forward, without moving the slide or head h, until the shank of r strikes the forward end face of the slot 1', or the end of the set-screw p, when the two slides or heads will move forward together until the limit of the forward movement is reached. On the return or backward movement of g the slide or head h remains stationary until the body of r and the end of o engage and cause the two slides or heads to move back together.

The ruffling-bladej is made from a piece of spring-steel or other suitable material, and has its forward end provided withnotches or teeth to catch the cloth or material, and an opening or slot for the passage of the needle, as usual. This blade, at its rear end, is firmly secured in any suitable manner to the under face of the slide h, and its length is such that when advanced by the forward movement of the slide or head to the end of its stroke the needleopening in its forward end will be in line with the needle-opening t in thebase or plate d, and it is held or supported so as to be freeto move and maintain the proper relation to the work by the guide 922,. secured to the under face of the support 0, in the form of construction shown, which guide has a suitable slot for the passage of the blade, and is made yielding to conform to the curve of the blade, so that in use the blade will not become straightened or lose its curvature and be rendered non-act- The size of the ruflles is varied as desired by giving the blade a long or short stroke, the short stroke producing a fine gather, and an increase in the length of stroke increasing the width or size of the gather accordingly. The length of stroke depends upon travel of the slide or head h. To produce a short stroke the end of the set-screw 0 is made to project but slightly, if at all, so that the engagement of the screw or pin 0' therewith or with the end face of the slot 1; will occur near the finish of the return or backward movement of the slide or head 9, giving the slide or head h a small degree of travel and withdrawing the blade j to that extent only. To increase the length of stroke the end of the screw 0 is made to project farther into the slot i, giving the slide or head h a farther length of travel backward by the engagement of the screw or pin r with the end of the screw 0 at a point farther forward, withdrawing the blade j a greater distance and increasing its stroke, the degree of increase depending on the projection of the screw 0 into the slot The retaining strip or plate h is made of a thin strip of steel or other suitable material, and is attached to the upper face of the holding-plate Z by riveting or otherwise, and is given a slight upward bend or curve to raise its forward end above the face of the plate I, and this forward end is provided with joints or teeth, which act to catch the cloth or material and prevent it from being drawn back by the withdrawal of the rufiler-blade. The holding-blade l is also made of a strip of steel or other suitable material, and is located beneath and in line with the rufiiingblade. Its rear end is attached, by rivets or otherwise, to a support, 0, and its forward end projects heneath the base or plate 11 in line, or nearly so, with the opening it, and this end and the forward end of the plate k are each provided with a slot or opening for the passage of the needle,which slots are in line with each other and with the needle-opening t.

The actuating link or pitman B is made from a single piece of brass or other suitable material having sufficient rigidity to operate the slide or head g. One end of this link or pitman is provided with a slot or opening, 8, for the passage of a set-screw, by means of which it is pivotally attached to the needle-bar, and the other endis pivotally attached to the slide or'head g by the set-screw q. The length of this link or pitman B is such in relation to the needle-bar and the slide or head 9 that the upward movement of the bar will advance the slide or head and the downward movement will recede the slide or head, the advance commencing at the commencement of the upward movement, and the recession commencing at the commencement of the downward movethe length of ment, the advance ceasing when the highest point of ascent is reached, and the recession at the lowest point of descent.

In use there will be more or less wear of the pivots and parts, causing lost motion to some extent, which might produce an insufficient advance of the ruffling-blade. This defect can be remedied and the blade be given the requisite advance by the set-screw 1), located in the forward end of the slide or head 71 the end of which can be made to project into the slot z, to be engaged by the set-screw or pin r in the advance of the slide at the proper point to advance the slide it the distance required to bring the forward end of the blade in correct relation to the needle. In the event the slide 9 does not have asufficient forward movement to advance the slide it far enough to proj ect the end of the ruffling-blade, as required, the end of the screw 1) can be made to project into the slot i to give the head It the required amount of forward movement by engagement with the screw or pin 1*.

The support C may be of the form shown, or of any other suitable form. Asshown, it is made from a single piece, bent to have two side pieces or arms connected at one end only. The free end of one arm is attached, by rivets or otherwise, to the side piece or arm, 6, and the free end of the other arm is left unattached and extends underneath the arm e and ruffling-bladej, and to its end is attached the holding-plate Z.

In use the device is attached to the presserfoot bar by the socket b and set-screw n, and the link B is attached to the needle-bar by a set-screw passed through the slot 8, or otherwise, and the cloth or material placed beneath the ruffling-blade. As the forward end of the link B is raised by the ascent of the needlebar the slide or head is advanced, and as the forward end of this linkis depressed by the descent of the needlebar the slide or head 9 will be receded, and these movements of the slide or head will give the ruffling-blade corresponding movements through the slide or head h, which movements of the blade form the ruffles, in the usual manner.

The length of the side piece or arm on which the slide g travels and its location and arrangement in relation to the needle are such as to allow the slide to move forward and back the distance required to permit the full stroke of the needle-bar to be made, and these parts and the link B have such relation to each other as that their movements will be perfectly free,

and so that the movement of one part will not interfere with the movements of the others.
