RUFFLING SEWING-MACHINE.

SPECIFICATION forming part of I ettersiatent No. 656,440, dated August 21, 1900. Application filed lune 2e, s rata, 721,918. (No model.)

an operating-bar receiving its movements To all whom, it may concern/.- I v Q Be it known that we, PHILIP DIEHL and MARTIN HEMLEB, citizens-of tlleUnited States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and'useful Improvements in Sewing-Machine Bufflers or Plaiters, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for its object to provide a sewing-machine ruffling or plaiting device in which the rufiling or plaiting blade .preferably has but one reciprocation for severalj stitches and which comprises a rotating pattern-wheel capable of variation by means of changeable pins, so that one plait may be formed for a greater or lesser number of stitches. In this improved ruliiingor plaiting device the ruffier or plaiter is preferably actuated independently of the needle-bar by from a constantlymoving vibrating arm which is automatically connected or coupled at intervals of severalstitches (and preferably for a single stitch at a time only) with the said vibrating arm, so that the rufliing or plaiting blade is operated to form one or more ruftles or plaits, and the operatingbaristhen automatically disconnected or uncoupled from said vibrating arm, so that the said blade may remain at rest for any desired interval.

In the accompanying drawings, Figure 1 is a front side view of the head of a sewing-machine with the face-plate removed equipped with the invention, Fig. 2 is a front end view, Fig. 3 a rear end view, Fig; 4 a rear side vlew, and Fig, 5a plan view, 'ofthesame.

Figs. 6 and 7 are detail'views of the pattern ratchet-wheel. 1 R y A denotes the head at the forward end of themachine bracket-arm A, l

of said lever, the latter being forked at c at its other end for engagement with a stud d on a vertically-reciprocatin g operating-bar D, which imparts movements to the said lever 0'. y l

The driving-shaft b is provided at the rear of the crank b with an eccentric b embraced by a forked arm 6 on a rock-shaft e, having its bearing in a bracket E, attached to the rear side of the head A, said shaft having a second arm 6 carrying at its forward end a sliding coupling-pin e adapted to engage a notch d in the operating-bar D. l

. Mounted on the shaft e, to rotate loosely thereon, is a pattern ratchet-wheel f, provided with holes f, in any desired numberof which may be fixed pins f having projecting pointed ends to engage a slide-rod f mounted loosely in the bracket E, so as to have a free endwise movement, said rod being pressed toward the ratchet-wheel f by a spring a on the arm 6 of the shaft 6. A spring-lever e pivotally attached to said arm 6 and engaging the coupling-pin 6 is so placed that its rear end is pressed against the slide-rod f by the spring e so that when the said slide-rod is forced outward by any one of the pointed pins f the forward end of the said spring-lever will press the pin 6 against the operating-bar D, and thus when said pin by the vibration of the constantly-moving arm 6 comes into register with the notch d of said operating-bar said pin will be forced into said notch and thus couple the saidoperatingbar D to the constantlyvibrating arm a to operate the ruffler to cause the blade thereof to form a plait between the time of formation of two stitches, the coupling-pin a being withdrawn from the bar Das soon as the point of the pin f passes the slide-rod f The are of vertical movement of the rear end of the spring-lever e is so short that said lever does not move outof contact with the outer end of the rod f The pattern ratchet-wheel fis intermittingly rotated by a spring-pressed pull-pawl g, carried by a lever G, pivoted at its lower end to the bracket E and provided above its pivot with a pin or roller-stud g, engaged by V a depending fork 2 attached to the arlne of the rock-shaft e, a detent-spring g preventin g backward rotation of said ratchet-wheel.

In the operation of the machine the pattern ratchet-Wheel f is intermittingly rotated and the rock-shaft e is in constant operation, so that the arm 6 carrying the pin 6, is moved up and down at each rotation of the drivingshaft or at each stitch being formed by the machine. When one of the pins f carried by the said ratchet-wheel comes-opposite the slide-rod f said rod will be forced outward to cause the'spring-lever e to press the coupling-pin a against the operating-bar D, so that when in the operation of the vibrating arm 6 the said pin comes opposite the notch cl in the said bar D said pin will be forced into said notch to couple said bar with the arm (2 and thus cause said bar to be reciprocated vertically to operate the ruffiing-blade and cause the latter to form one or more ruffles or plaits, after which by the disconnection of the coupling-pin c from the bar D the further movement of the said bar will be suspended until another of the pins f comes into register with the slide-rod f Thus the number of stitches to be formed between each plait will be determined by the distance apart of the pins f in the pattern ratchet-Wheel f, said ratchet-wheel being moved forward one tooth at each rotation of the driving-shaft or during the time each stitch is formed by the machine. Any desired number of pins can be inserted in the holes of the ratchet-Wheel f, and by changing the number, positions, or forms of said pins the pattern of the plaiting may be varied-without changing the patternwheel, as will be understood.

By operating the ruflier or plaiter from an independent bar instead of from the needle bar of the machine, as heretofore, the needlebar is relieved from this extra duty, while the independent operating-bar adapts the construction to an automatic connection and disconnection of the rut'tler or plaiter operating device with and from its actuating mechanism, so that the machine is adapted to form one plait for any desired number of stitches, or if the projections on the ratchet-wheel be of proper form the machine is adapted to make any desired number of consecutive plaits, one at each stitch. 1

We do not wish totbe understood as limiting our invention to the details herein shown and described, as these may be varied Widely without departing from the spirit of our invention.

' Having thus described our invention, we

claim and desire to secure by Letters Patent 1. The combination with a sewing-machine ruffling or plaiting attachment provided with an actuating-lever, of an operating device, independent of said attachment, for said lever,

an actuating mechanism for said operating dean operating-lever, of an independent operating-bar for said lever, an actuating mechanism for said operating-bar, and automatic means for connecting and disconnecting said actuating mechanism and operating-bar.

3. The combination with a sewing-machine ruffling or plaiting attachment provided with an operating-lever, of an operating-bar connected with said lover, a rotating patternwheel for controlling the movements of the ruffling or plaiting blade of said attachment, a vibrating arm for actuating said bar, and a coupling device, controlled by said patternwheel for connecting and disconnecting said arm and bar.

t. The combination with a sewing-machine ruffling or plaiting attachment provided with an operating-lever, of a vertically-reciprocating bar in the head of the machine and independent of the needle-bar, and connected with and serving to operate said lever.

5. The combination with a sewing-machine ruftling or plaiting attachment provided with an actuating-lever, as c, of the independent operating-bar D connected with said lever, a vibrating arm for operating said bar, and automatic means for connecting and disconnecting said arm and bar.
