SPINNING OR TWISTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 747,893, dated December 22, 1903.

Application filed September 18, 1903. Serial No. 173.646. (No model.)

To all whom it may concern:

Be i t known that I, THOMAS SAMPSON, a citizen of the United States, residing at Water- Ville, in the county of Kennebec and State of Maine, have invented an Improvement in Spinning or Twisting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to machines for spinning, twisting, or doubling yarns, and more particularly to such machines employed in the treatment of woolen or worsted yarns wherein the yarns or threads pass from delivery-rolls to bobbins mounted on rotating spindles to be wound thereon by or through the medium of a ring and traveler device. In treating woolen and worsted yarns on such machines considerable trouble is experienced from the doubling of the threads, due to the broken end of one thread engaging an adjacent intact thread and being carried therewith to the bobbin, so that the thread will be double for more or less of its length, depending on the time which elapses before the attendant notices and corrects the fault. Separators of various types have been interposed between adjacent spindles to prevent the ballooning of adjacent threads from interfering; but such separators do not obviate the fault before noted, as the broken end will fly around the upright edge of the separator and when engaged by an intact thread will draw off over such edge until discovered.

My present invention has for its object the production of simple and effective means for obviating the fault referred to, and I have also provided means for preventing waste, due to abroken end, from becoming entangled with or picked up by an adjacent thread.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims. Y

Figure 1 is a front elevation of a portion of I a spinning or twisting machine of well-known construction with one embodiment of my invention applied thereto. Fig. 2 is a transverse sectional view thereof on the line 2 2, Fig. 1, looking toward the .left. Fig. 3 is a perspective view detached of a combined thread guide and parter embodying my in- .vention, and Fig. 4 is a similar view of a well-known construction and operate in a manner familiar to those skilled in the art..

In the present embodiment of my invention 1 hinge to the front edge of the roller-beam a series of preferably sheet-metal plates I), each plate having suitable hinge members b to receive pivot-pins or pintles 12', carried by the roller-beam. Each plate is provided with a thread guide or eye, preferably inte- 7o gral therewith and formed by anopening I) punched or otherwise made in the plate above the spindle, a slot 17 from the front edge of the plate leading to the eye in order that the thread may readily be inserted therein. By making the guide-eye integral with or a part of the plate I do away with the usual pigtail or pot-eye now commonly used and which are made separate and secured to a support connected with the rollerbea m. The plates are interposed between the spindles and front delivery-rolls and so located with relation to the latter (as will be manifest from an inspection of the drawings) that if an end breaks above it the thread will fall 8 upon the top of the plate and be sustained thereby until removed by the attendant when the end is pieced up.- At one of its side edges each plate is upturned or flanged to present a stop a at right angles to the line of spindles. This stop serves to prevent waste collected on the plate from blowing or spilling over the side thereof onto the next thread or end and becoming entangled therewith, it being manifest from Fig. 1 that while the stop guards 5 one side of its plate the opposite side is guarded by the stop on the next plate. Such waste as collects can be readily removed and in such condition that it may readily be utilized, and it is effectually prevented from dropping I00 down into the machine or onto the floor, as well as from being picked up and wound in by an intact end. Ordinarily the ends are led from the rolls to the travelers through pigtails or pot-eyes mounted on blocks hinged on the roller-beam, and if an end breaks the thread or yarn above the pigtail, due to the continued operation of the rolls, will fall upon the bobbin beneath it or into the machine, or it may be blown sidewise and picked up by an adjacent end, tending to break the latter. These objections are overcome entirely by the device hereinbefore described, and breakage of ends from such cause is reduced to a minimum.

At its side edge opposite the stop 0 each plate I) is provided with a depending bladelike portion d, which is substantially midway between two adjacent spindles and herein shown as wide as the plate I) is deep. The lower edge of such portion cl, which I term a thread-parter, is a short distance below the upper end of the bobbins. This blade-like member at acts to a certain extent and secondarily as a separator, inasmuch as it limits the ballooning of the threads on each side thereof; but it will be obvious that it is much shorter than the ordinary separator, the latter usually being so arranged that its lower edge closely approaches the ring-rail at all times. Primarily, however, the member d has a very different purpose and operates in a manner wholly different from the usual separator. If an end breaks down between the traveler and the plate 6, it tends to flyover to one of the threads adjacent and be carried thereby around the top of the bobbin, as shown in dotted lines, Fig. 1, the broken end being drawn under the lower edge of the member 01. As 'the broken end winds upon the top of the bobbin the strain thereby exerted on the end draws it taut across the lower edge of the blade-like member (Z and breaks or parts it, the short piece thus left usually being thrown ofi the bobbin by centrifugal force. The remaining piece hanging below the plate I) is too short to do any damage to or become entangled in adjacent threads, and as the rolls continue to deliver the thread it collects on top of the plate, as has been described.

The plates 1) may be made of any suitable material, metal or wood, and if made of metal the stop and thread-parter are conveniently and cheaply made integral therewith. If the plate is made of wood,the stop and threadparter will be made of sheet metal and firmly secured thereto.

If desired, the lower edge of the threadparter may be toothed or serrated, as at d Fig. 4, to increase the parting action on the thread or yarn.

By hinging the plates to the roller-beam they may be turned up out of the way for doffing, and when in use the plates are maintained substantially horizontal by the engagement of the rear edges of the thread-parters with the front edge of the roller-beam, as shown in Fig. 2.

My invention is not restricted to the precise construction and arrangement herein shown and described, as the same may be varied or modified in difierent particulars by those skilled in the art without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. In a machine of the class described, a plate having a thread-guide formed integrally therewith, and a blade-like threadparter depending from one edge of and integral with the plate.

2. In a machine of the class described, a plate hinged at its rear edge and having a thread-guide formed in it, and a blade-like thread-parter depending from one side edge of and integral with said plate.

3. In a machine of the class described, a plate having an integral thread-guide, and provided at one side edge with an upturned stop and at its opposite edge with a depending thread-parter.

4. In a machine of the class described, a series of plates adapted to be sustained side by side, substantially horizontal, each of said plates having a thread-guide formed therein and presenting a surface upon which broken threads may accumulate, an upturned stop at one of the side edges of each plate, and a downturned thread-parter at the opposite edge.

5. Delivery-rolls, a rotatable spindle beneath them, a normally horizontal plate interposed between said rolls and spindle and presenting a fiat surface upon which may be deposited a broken thread delivered from the rolls, the plate having a guide-eye integral therewith and a slit leading to the guide-eye from one edge of the plate, and an upturned stop at one of the side edges of and integral with the plate.

6. Delivery-rolls, a rotatable spindle below them, an interposed, normally horizontal plate interposed between said rolls and spindle and having a guide-eye and aslit leading thereto from one edge of the plate, the plate presenting a surface upon which may be deposited a broken thread delivered from the rolls, and a depending bladelike threadparter at one of the side edges of the plate, to engage and part a broken end when drawn across its lower edge.

7. Delivery-rolls, a rotatable spindle beneath them, a normally horizontal plate interposed between said rolls and spindle and presenting a flat surface upon which may be deposited a broken thread delivered from the rolls, the plate having a guide-eye therein, an upturned stop at one of the side edges of the plate, and a depending blade-like threadparter at the opposite edge thereof, to engage and part a broken end when drawn across its lower edge.

8. Delivery-rolls, a rotatable spindle beneath them, a normally horizontal, pivotallymounted plate projecting above the spindle and having an integral guide-eye, an upturned stop at one side edge, and a depending thread-parter at the opposite edge of the plate, both integral with the plate.
