WILLIAM MASTERSON, OF NORTH SMITHFIELD, RHODE ISLAND, ASSIGNOR TO JOHN S. NEEDHAM AND JOSEPH TAYLOR, OF BLAOKSTONE, MASS.
IMPROVEMENT 1M STOPPING MECHANISMS FOR D0UBL|NGMACH|NES,&0.-
Specification forming part of Letters Patent No. 158,295, dated December 29, 1874; application filed October 2, 1874.
To all whom it may concern:
Be it known that I, WILLIAM MAsrERsoN, formerly of Blackstone, in the county of lVorcester and Commonwealth of Massachusetts, but now of North Smithfield, in the State of Rhode Island, have invented certain new and useful Improvements in Stop Motions for Winding and Twisting Machines, and for other purposes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings forming a part of this specification, and in which- Figure 1 represents a top or plan view of so much of a winding and twisting machine as is necessary to illustrate my improvements in stop-motions for winding and twisting machines, and for other purposes. Fig. 2 represents a vertical section on line A B, Fig. 1. Fig. 3 represents a front view of a detached part; and Fig. 4 represents a section of a detached part, as will be hereafter more fully described.
To enable those skilled in the art to which my invention belongs to make and use the same, I will proceed to describeit more in, detail.
The object of my present invention or improvements is to obviate more particularly the objection incident to the present winding and twisting machines used in the manufacture of worsted, and other similar productions.
In the drawings, the part marked A represen ts therail upon which the bobbins of worsted or other thread or yarn, B B, are supported while their threads to a are drawn oft, twisted together, and wound upon a bobbin in the usual manner. Rail A is provided with spindles b, upon which the bobbins turn. The threads to a, to be doubled and twisted, are passed under the hooked ends 0 c of lever O U, inthis instance made of wire, with coils d, which serve to receive a fulcrum-pin, 0, upon which said levers are free to vibrate, so as to fit under the head D of piston E, which is fitted so that it can work up and down freely in a hole in the-thread-guide F, which is shown in section, Fig. 4. The hole in the threadguide F, in which the upper end of piston E known winding and twisting machines.
works, is intersected by hole 1, which is bored entirely through the thread-guide F, and a.
slot, 2, is cut in one side of the thread-guide F, so that the threads a can be slipped into hole 1 by drawing them into slot 2. The up- It will be understood, however, that myimproved stop-motion for winding and twisting machines, and for other purposes, can and is to be applied to any of the common and well- In the drawings the unbroken threads are indicated by full lines, and the broken threads by dotted lines.
The operation is as follows: Assuming that the threads upon bobbins B B are to be doubled and twisted, they are first caught under the hooked ends 0 of levers (l G, whereby the rear ends of said levers are drawn up, as shown in full lines, Fig. 2. The threads are then slipped into slot 2, and drawn into and through hole 1 in thread-guide F, after which they are passed through the ordinary rolls, which draw off the threads from bobbins B B, and deliver the doubled thread to the ordinary twisting apparatus, by which it is twisted and wound upon bobbins in the usual way. In case oneof the threads breaks, the rear end of its lever C will fall, as indicated in dotted lines, Figs. 2 and 4:, thereby throwin g headD and piston E up, as shown in dotted lines, same figures, and as the upper end of piston E passes slot 2 and hole 1, it catches the unbroken thread or threads, as the case may be, and carries them up and securely binds them against the upper edge of hole 1, thereby causing all of the threads to break, thus preventing one or more of the threads being drawn 01f and deliveredto the twisting mechanism after one thread has broken. Only two threads, a, are shown in the drawing, but any desired number may be run through to be doubled and twisted together. The head I) of piston E is caused to rest, by its gravity and that of piston E, upon the ends f of the short arms of levers 0. Consequently, after piston E has been raised by the breaking of one of the threads, as before described, and has clamped or broken the remaining thread or threads, as indicated in Fig. 4, it will fall again to the position shown in full lines, same figure, as soon as all the levers O are raised again to the position shown in full lines, Fig. 2, thus permitting all the threads to be easily inserted through slot 2 into hole 1 and threadguide F. Piston E is made round in this instance, but its shape may be varied without changing the principle of its operation. Levers O (l are pivoted, in this instance, upon a journal or pin, 0, which passes through the upper ends of the legs G G of the threadguide F; but they may be pivoted in a different manner, provided they are so arranged as to act upon piston E, to break and stop the thread or threads, as before explained. The upper end of piston E, which clamps and breaks the thread or threads, as the case may be, may be made in a different form from that shown in the drawings, and still answer the purpose of a thread stop or breaker; but I prefer the form shown, since it is calculated to gather the threads, when a number are used, in such a manner as to insure their being stopped and broken at the same time.
Those skilled in the art to which my invention belongs will readily appreciate the great practical value and importance of my improvement, since it prevents not only a great amount of waste, but saves a great deal of time of the operative in unwinding yarn from the bobbin in the twister, which has run on without the full complement of threads. Tl'len, again, it prevents any number of threads less than the full complement being twisted and wound upon the bobbin, which careless or indifferent operatives frequently allow to pass into the subsequent operations of manufacture, thus damaging the goods and rendering them unsalable.
Having described my improvements in stopmotions for winding and twisting machines, and for other similar purposes, what I claim therein as new and of my invention, and desire to secure by Letters Patent, is
1. The combination, with the thread-guide F, provided with hole 1 and slot 2, of piston E, having its upper end beveled, substantially as and for the purposes set forth.
2. The combination, with piston E and piston-head D, of one or more thread-levers, 0, provided with a thread-hook, c, and a pistonlifting projection, f, substantially as and for the purposes set forth.
3. The combination, with stand G, provided with legs G G, of slotted thread-guide F, piston E, provided with piston-head D, and one or more thread-levers, O, substantially as and for the vpurposes set forth.
WILLIAM MASTERSON.
