SEWING-MACHINE RUFFLER.

SPECIFICATION forming part of Letters Patent No. 271,679, dated February 6, 1883.

' Application filed August 7, 1882. (No model.)

To all whom it may concern: v

Be it known that I, GEORGE W. BAKER, of Cleveland, in the county of Cuyahoga and btateot' Ohio, have invented certain new and useful ltnprovementsin Sewing-ll/lachine Ruffiers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it .pertains to make and use IO the same.

My invention relates to ruffiers; and it consists in the parts and combination of parts, as will be hereinafter fully set forth and claimed.

1n the drawings, Figure 1 is a. plan view ofa device embodying my invention. Fig. 2 is a view in elevation of the same,looking at it from the front. nal section, looking at it from the rear.

Fig.

.4 is a plan view, showing another manner of constructing my device. Fig. 5 is a plan view of a piece of goods after it has been operated upon by the ruffler. Fig. 6 is a detached view of the lever G. Fig. 7 is a perspective view of the ruffler.

A is a presser-foot, to which is secured the ruffler, which I prefer to construct similar to the well-known Johnson ruffler.

Theruffling-blade B is reciprocated by means of the pivoted crank-lever 0, one end of the arm a of which engages with a set-screw on the needle-bar D, and the end of the other vertical arm, I), engaging with lugs c and d, extending upward lrom the sliding plate E. The sliding plate E is in turn pivotally attached to the ruffiiug-blade B. Thusit will be seen that as the arm a ofthe crank-lever C is reciprocated vertically by the needle-bar D vertical arm I; will be reciprocated horizontally, and impart through the lugs c and d a horizontal reciprocatingmotion to theplate E and blade B.

F is a ratchet-wheel journaled on an extension to the rtiffler-trame.

eis a wrist or pin secured to the ratchetwheel F, which acts to operate the lever F by engaging with a slot, f, as shown in Fig.1. The lever F is pivoted near its other end, atg, and provided with a slot, it, running at aright angle to the said lever. Thus it will be seen that as the wheel F is revolved the lever F is Fig. 3 is a view in longitudithe slot h to occupy different positions, either parallel with the blade B or at different augles to it.

t'is a stud or pin which is secured to the blade B, and extends upward through the slot h, and serves to guide the forward end of the blade B in the direction of the sloth.

The-ratchet-wheel F is operated by means of the pivoted crank-lever G,whicl1 is journaled on the same screw or shaft with the 6-3 ratchet-wheel F. One arm,'j, of said cranklever G is in such a position as to be operated by a lug, It, which extends out from the side of the sliding plate E. (See Figs. 4 and 6.) The other arm, l, of the crank-lever G is pro- 6 vided with a pawl, m, which engages with the teeth of the ratchet-wheel F and imparts intermittent rotary motion to the said wheel F.

H is a spiral spring, one end of which is Socured to the ruffler-t'rame, and the other end is secured to the pawl in in such a manner as to keep the said pawl in contact with the teeth of the ratchet-wheel F, and also to keep the arm j in contact with the lug 7t.

Instead ofemploying a pivoted lever, F, with a slot, f, for the wrist or pin 6 to operate in, as shown in Fig'. 1, I may employ a pitman, F, as shown in Fig. 4, which is pivotally secured to the wrist or pin 0, the other end of the pitman being pivoted to the plate I, which in turn is pivoted at 0, Fig. 4, by means ofa hollow pivot, through which the needle passes, and its free end 17 is provided with a slot, 1', into which fit two pins, 8 s, which extend upward from the rattling-blade B. 8

Instead of pivoting the end of the blade 13 to theplate E, as in Fig. 1, I provide a slot, t, which allows this end to slide as the blade 13 is guided by the slot r.

The length of the stroke or movement of the 0 arm I and pawl m is regulated by means of the pivoted lever J, which acts, when moved in the direction of the arrow, Figs. 1 and 4, to limit the distance to which the spring H shall pull the arm lback. K is a guide, through 5 I which the piece of goods to be ruffled passes, and it consists of the two lugs a and 1), which extend upward from the frame K of the guide,

moved from one side to the other, and causes 50 and a spring, 10, which extends into slots formed in the lugs. The goods are passed between thelugs u and 'U and under the spring to.

L is a spring-shield which extends over the feed of the sewing-machine, and on the upper side of which rests the teedingedge of the ruffiing-blade B.

The operation of my device is as follows: The piece of goods to which the rufiile is attached or sewed is placed under the shield L, so as to be operated upon by the feed of the sewing-machine. The piece to be rattled is then passed under the spring to of the. guide K, and also along under the rattling-blade B and over the shield L, so as to be operated upon only by the rufliing-blade B. The machine is now staited, and as the needle-bar is driven up and down the blade B is reciprocated by means ot'the cranlclever and sliding plate, hereinbefore mentioned, and acts to feed the piece of goods to be ruflfled. Now, at every fot ward stroke of the blade B and plate E the lug It acts to move the armj of the crank- ]evcr G, and cause the pawl m on the at tn lto engage with the teeth of the ratchet-wheel F and move it. ashort distance which in turn causes the wrist or pin a to operate on the lever or pitman F, which acts to change the direction of the slot in which the pin or pins extending upward from the blade B slide, and thus the direction in which the forward end ofthe blade B moves is changed as the ratchetwheel F is rotated. This causes the blade to feed the cloth ofwhich the rufiie is to be formed at an angle corresponding to the angle of the slot in which the pin or pins slide, and as this angle is changed at every forward stroke of the blade B the scalloped ruflfle shown in Fig. 5 is formed.

What I claim is 1. In a sewingmaohinc rather, the combination, with a ruffling-blade, of devices, substantially as described, whereby the line of tnotion of said blade is changed at each stroke and the blade reciprocatcd at different; angles for the purpose of forming scalloped rnfiiin 2. Ina sewingranachine rufller, the combination, with the rufiiling-blade,of devices for guid ing the blade and changing its line of tnotion while in operation, substantially as set forth.

3. In a sewing'machine rather, the combination, with theruffling-blade, of devices for guiding the blade and changing its line of motion at each stroke thereof, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE W. BAKER.
