4 Claims.
This invention relates to thread guides such as are used on textile machines for the purpose of guiding the yarn or thread, and particularly to reciprocating thread guides or yarn guides such as are used on coning machines.
These reciprocating guides constantlysupport" the yarn as it is being wound, and thus wear out very quickly, requiring frequent replacements.
This replacement of worn guides has thus far considerably increased the manufacturing costs of yarn producers.
Moreover, these worn thread guides have frequently caused damage to the thread, particularly in the winding of artificial silk thread which is composed of a great number of fine individual filaments. v
It is, therefore, one object of the present invention to provide an improved thread guide which possesses greater resistance to wear.
A'further object'is the provision of an improved thread guide which will cause less damage to the yarn.
These and other objects will become apparent from a study of the following description, taken with the accompanying drawing, in which! Fig. 1 is an end elevation partly in section of a conventional winding mechanism showing the thread guide in operative position;
Fig. 2 is a front elevation of the. thread guide mounted in a standard guide holder commonly used in connection with textile machinery;
Fig. 3 is a cross-sectional top view along'lines 3--3 of Fig. 1; and
Fig. 4 is a perspective view of the guide by itself.
Referring to the drawing, the portions of the conventional winding machinev shown in Fig. 1 comprise a cone or other core H) which is supported by a spindle (not shown) for rotation therewith. Upon rotation of the core l a yarn package H is built up thereon. A weighted lever I2 is pivoted below the spindle at l3 and has a groove formed near its upper end receiving a traversebar I4 which is reciprocated by a cam mechanism (not shown). A supporting metal arm I 5 has a foot or laterally extending flange l6 secured to the traverse bar, a retaining tongue therefor, and an upper end on which is mounted a yarn guide l8.
This thread or yarn guide l8 which is secured to the supporting arm l5 by shellac or the like comprises a smooth piece of material having a low coeflicient of friction, such for example as porcelain or glass, with a convex bearing surface or core III or the yarn package wound thereon as it is rotated. The thread guide I8 is provided with a- V-shaped notch 20 extending centrally through the'convex surface I9. The bottom 2| of this notch is shaped to provide a narrow surface convexly curved from front to rear of the guide I 8 and having its highest point intermediate its length. v
According to the present invention the convex surface IQ of thread guide I8 is provided with a uniform vertical groove 22 which extends as a smooth continuation fromthe front end 23 of the notch bottom 2| to thelower end 24 of the convex surface. This groove 22 has a width several times the thickness of the yarn to be wound and a depth at least slightly greater than the thickvertical groove 22 and passes onto the core ill on which the yarn package I is formed.
The yarn body I] increases in thickness as the winding progresses and, as a result, the thread guide |8 which rests against the yarn body and which is supported on the counter-balanced lever l2 for pivotal movement therewith is forced outwardly and away from the axis of the core l0. Consequently, the point of contact of the thread guide I8 with the yarn body II is gradually and progressively shifted towards the lower end 24 of the convexly curved bearing surface 13.
Since the thread or yarn always travels within the groove 22, the friction between the thread and the yarn body being formed, as a result of the reciprocation of the thread guide l8 along the surface of the yarn package, is greatly minimized and injuries to the thread which would ordinarily occur with the use of the conventional type of thread guide are eliminated.
Heretofore, the point of greatest wear on the thread guide was to be found in the notch 20 at the termination of its bottom 2| on the front face of the bearing surface I9. This wear consisted in furrows caused by the thread at this point in the bottomof the notch 20 because the thread was not free to move laterally at the front end 23 of the surface l9 as the thread guide recipro- IE! to rest against the lateral surface of the cone Oated- In the thr guide pr n t e present invention, however. the notch bottom 2| tar-- groove 22 during the reciprocation of the guide ll, thus resulting in substantially less formation of furrows in the thread guiding surface and materially less wear on the thread guide.
What I claim is: f
1. A thread guide comprising a body of material formed to provide a convex surface adapted to bear against a winding core and having a notch extending downwardly from its upper edge, the bottom of said notch being convexly curved, and an up and down groove in said convex surface forming a smooth continuation of the adiacent end of the bottom of said notch and being of a greater width than the thread to be guided and of a depth sufficient to receive said thread completely. 4
2. A thread guide for use in winding or coning machines and comprising a body of material formed to provide a convex surface adapted to bear against a winding core and having acentral V-notch extending downwardly from its upper edge, the bottom of said notch being upwardly arched, and a uniform up anddown groove in said convex surface extending as asmooth conface and being several times the width of. the
thread to be guided and of a depth suflicient to receive said thread completely.
3. In combination with a thread winding machine having a horizontally extending core and e a thread guide support reciprooable lengthwise with respect to the core and pivotally mounted for movement away from the core as the thread body is formed: a thread guide mounted on the tom surface, and a thread-receiving vertical groove extending from the bottom surface of said notch to the lower edge of the convexedsurface.
4. In combination with a thread winding machine having a horizontally extending core and a thread guide support reciprooable lengthwise with respect to the core and pivotally mounted for movement away from the core as the thread body is formed: avitreous thread guide mounted on the support and having a smooth convexed surface adjacent the core, said thread guide being formed with a central V-notch extending downwardly from its upper edge and having an upwardly arched bottom surface, and a uniform thread-receiving vertical groove having the depth of and several times wider than the thread to be guided extending from the bottom surface of said notch to the lower part of the convexed surface.
