2'0 aLZ/I who/it it may concern.-
Be it known that I, LEON W. CAMPBELL, of WVoonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Spinning or Twisting Frames, of which the following is a specification.
This invention has relation to spinning or twisting frames, and has for its primary object the provision of means for decreasing and in a large measure preventing the waste of yarn that has hitherto been due to the breaking of the ends and the wrapping or coiling of the latter about the rolls.
My invention is intended to utilize the power that rotates the drawing-rolls to directly cause the second breakage of a broken roving at the receiving side of the rolls, thus enabling the desired result to be produced with greater certainty and-by more simple and reliable means than have been heretofore used.
The invention consists in the improvements which I will now proceed to describe and claim.
Referring to the accompanying drawings, which illustrate one embodiment of the invention, Figure 1 represents in front elevation the upper portion of a spinning or twisting frame. Fig. 2 represents a section through the same from front to rear. Fig. 3 represents a perspective view of a device embodying my invention.
Referring to the drawings, a portion of the spinning-frame is shown which differs in no respects in its essential features from those ordinarily employed. Three sets of drawingrolls are used, as is ordinarily the ease, (indicated at a a, I) Z), and c d.) The top rolls are mounted in the usual manner in operative relation to the lower rolls, that at 0 being preferably shod with leather or other suitable material and that at (Z being formed of steel and being fluted in the usual way.
The strands a: and y come from reels and pass through the thread-eye e to the rolls. Thence they extend to the pigtail or threadeye f. In the rear of the rolls there is a rod g, which is usually employed in machines of this character.
My invention, according to its illustrated embodiment, comprises a stand h, arranged between each pair of fluted portions of the roll d. Each stand has a stud-shaft 1 projecting fromeither side thereof. Journaled upon each projecting end of the shaft there is a partial roll j, equipped with. a rearwardly-extending arm is and with a forwardly and downwardly projecting weight Z. Gonnected to the arm 7c is an adjustable extension m, having an upturned end 12 projecting through a slot in the rod g. This end at is slotted, as at o,to form a thread-eye, through which the strands :r y may pass. The end projects normally above the periphery of rod g, being held in that position bythe weight Z, which is just sufficient to overcome and counterbalance the weight of the arm and the extension at. a
The partial rollj is set close to the periphery of the roll (I, in fact, so close that when the roving is coiled once or more about the roll it will engage the periphery of the roll j and cause said roll to be rotated in the direction of the arrow. This swings the arm 70 downwardly and the yarn is nipped by the wall of the thread-eye e, which constitutes a movable roving-clamp member,-against the rod g, which constitutes a fixed roving-clamp member,with sufficient force to cause the reving to part under the tension exerted by the rolls a a.
I have found by experience that when the roving is parted in this way the fibers on the end of the strands lie between the rolls, so that upon releasing the roving it will be gripped by and carried through the rolls automatically.
I prefer to adjustably connect the arm 7t and the extension m, as the stand 71. may be adjusted when the rolls are varied in position without affecting the relation of the end a of the extension and rod 9. This adjustable connection may be provided by the fiangesp, which are bent upward and inward to embrace the arm k, as shown in Fig.
. It will be seen that by my invention above described the power that rotates the rolls is directly utilized to stop the delivery to the rear rolls of any single roving that has been broken between the front rolls and the spindles,such roving being again broken at a point behind the rear rolls. By thus utilizing the power applied to the rolls the second breakage of the roving is effected more certainly and positively than would be the case if the roving-breaking mechanism were controlled or actuated by a yielding force, such as a weight or a spring, and the mechanism involved is more simple and reliable.
The phraseology employed by me in this specification, as well as in the appended claims, is for the purpose of description and not of limitation, and I intend in no wise to therebylimit myself to any particular details of construction for which mechanical equivalents may be employed.
The partial rollj constitutes a normally idle member of a couple of rotation, the other member of which is the rolld, said normally idle member being made operative by the accumulation of a roving on said lower roll.
It will be seen that the clamp is held continuously closed after the action of said couple untilitis opened by the attendant and that the end of the broken roving is held in the nip of the first pair of drawing-rolls ready for antomatic engagement with said rolls when the clamp is opened.
Having thusexplai'ned the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is 1. A spinning or twisting machine having a plurality of means each controlled independently by the accumulation of one of the single rovings upon one of the rolls for continuously'clamping or grasping the same roving at a point adjacent to the receiving side of the series of rolls,whereby the power which rotates the rolls is utilized to again break any single roving,and stop its delivery to the rolls, the broken end being left in position for antomatic engagement with the nip of the rolls at the receiving side.
2. In a spinning or twisting machine, the combination with the drawing-rolls, of a roving-clamp adjacent to the receiving side of the rolls, and clamp closing means, comprising a normally idle member of a couple of rotation, the other member of which is the lower roll of the front drawing-rolls, and connections between said idle member and the clamp, the said idle member being in close proximity to said lower roll whereby upon the breakage of a roving at the delivering side of the rolls, and the accumulation of the roving upon said lower roll, the said idle member is actuated to operate the clamp.
3'. In a spinning-frame, drawing-rolls, means to stop delivery of the roving, said means comprising two apertured and relatively movable members normally forming a roving-guide, and means actuated by or through accumulation of roving upon breakage of the thread, to effect relative movement of said apertu red members and part the roving.

In testimony whereof I have affixed my signature in presence of two witnesses.
