STOP-MOTION FOR QUlLLlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 396,384, datedJanuary 22, 1889.

Application filed February 1, 1888. Serial No. 262,593. (No model.)

To all whom it may concern-.-

Be it known that l, DWIGHT ASHLEY, of the cit-y of Paterson, in the county of Passaic and State of New Jersey, have invented a certain new and useful Stop-Motion for QuillingWIachines, of which the following is a specification.

My invent-ion relates to quilling-machines for silk, and is designed to facilitate doubling and quilling in one operation.

The object of my invention is to provide an improved automatic stop-motion, so that one, two, or more threads, each coming from a separate bobbin, may be brought together and wound on a quill, and the quill-spindle be stopped when one or more of the threads which are being wound by that spindle break. I attain this object by means of the mechanism hereinafter described, and illustrated in the accoinpanyin drawings, which form a part of this specification.

In the drawings similar letters and figures of reference indicate like parts.

Figure-1 is a sectional end view of the principal parts of a quilling-machine with my invention attached. Fig. 2 is a front view of one spindle and most of the parts of my stopmotion relating to that spindle. Fig. 3 is an end view showing only those parts which comprise my invention. The illustration shows the position of the parts when the spindle is in operation. Fig. 4 shows the relative position of the tilting lever and other parts, the latch-lever and reach-rod being shown in section. Fig. 5 is a detail of the latclrlever. Fig. 6 is atop viewor plan of part of my invention, showing the taper piece used to push the rock-lever sidewise.

The frames A and studs l3 3 form a framework, and, together with the spindle D spindle-disk D, and spindle-shaft I), the back shaft, e, carrying the friction-cone e, the friction-cone D on spindle-shaft D, the buildingrod f, the tension-rod C, the main shaft G, pulley G on the main shaft, and the pulley on the back shaft, which drive the spindle through the intervention of back shaft, 6, and cones 6 D form, together with the tight and loose pulleys X, part of a quilling-machine which is given only to illustrate the application of my v invention.

My stop-motion is mounted partly on the bracket A and partly on the back bar, 13*, and girt A I is a drop-wire pivoted on the pin 1, which 5 5 is held in a bracket secured to girt I I is provided at its upper end with an eye for a thread. Several of these drop-wires are mounted in front of a tilting lever, J, and either of them, if not held against the stoprod 1 by the tension of the silk, would fall back and strike the tilting lever J.

J is a tilting lever hanging loosely on pin J, which is fixed in a bracket secured to girt J The tilting lever J is slotted, J Figs. 2 and 3, and is provided with a pin, J When the spindle is running, lever J leans against a fixed stop-rod, R.

L is a reach-rod, which passes through a slot in the bracket K and extends backward over the back bar, B and between two pins, B fixed in back bar, B It is provided with a taper piece, N, bearing against the rock-lever V, Figs. 2 and 3, pivoted at V, and also with a tension-spring, N, which tends to draw it backward. It is prevented from being drawn backward by the latch-lever K. The motion of rod L in the direction of arrows 102 is limited by the pins 0 O, which strike the pins The latch-lever K is pivoted at K in bracket K K being fixed to girt J The front end of the latch-lever is heavier than its back end; hence its back end lifts into the notch L, Fig. 3, in the reach-rod L, and holds the rod against the action of the spring N, and in the position shown.

P is a toothed wheel secured to shaft M, which is continually revolved by a belt, H, running from pulley II on the main shaft to pulley H X represents tight and loose pulleys on the main shaft.

V is a rock-lever mounted pivotally at V, the upper end of which forms the back bearing of spindle-shaft D.

A tension-spring, U, Fig. 2, which connects lever V to girt A holds the friction-cones e and D in contact. If this spring U were overcome and the rock-lever moved in the direc- I00 tion 101, Fig. 2, the friction-cones would be separated and the spindle would stop. The

thence directly to the quill, which is placed on the quill-spindle D The quill-spindle is placed eccentrically upon the spindle-disk, and is carried around the end of the building- .rod in order to wind the silk upon the quill. Any of: the drop-wires I not in use maybe tied to the stop-rod 1 It a thread breaks,

the drop-wire through which it passes falls piece used as a wedge, and having a spring 1 ioedrawing the same backward when unbackward and strikes the tilting lever J, which tilts toward the position represented by the line J i The pin J in lever .T engages in teeth of wheel 1; hence lever J is forced into position J, and raises the front end of latch-lever K. This drops its lower back end out of the slot in red L, which is then drawn backward by the spring N, and the taper piece N pushes the rock-lever V in direction 10.1, as required to stop the spindle. The

broken end is then tied up and the spindle restarted by pulling rod L forward and pushing lever J into the position shown, when the latch-lever K holds rod L in position. The

slot J allows the pin J to lift over the teeth in wheel P.

The stop-motion may be used either when the spindle is moved back and forth or when the buihling-arm is moved as indicated in Fig. 1.

'With this description of my i nvention, what I claim is' In a stop-motion or doubling attachment for quiHing-machines, a rock-lever which carries one end of the quill-spindle shaft provided with a tension-spring, a tilting lever provided with a'pin and a slot, as illustrated and described, a reach-rod carrying a taper latched, and stop-pins to limit its backward and forward motion, a latch-lever which acts by gravity, a revolving toothed wheel which engages with a pin in the tilting lever to force it backward, and the drop-wires shown and described, and for the purposes described and set Forth.
