SHUTTLE.
Application filed December 2, 1927. Serial No. 237,179.
The present invention relates to an improvement in shuttles.
1n sill; shuttles a pivoted tension lev-er having a plurality of thread eyes on one arm, has
lone` been used in connection with a `series ot pins to apply tension to the yarn being discharged by the shuttle. The `other arm of the tension lever has been attached to one end of aV piece of rubber elastic, the other end of the elastic being secured to a pin in the shuttle, the pull ot the rubber elastic tending to move the tension lever in the direction to cause it to take up the yarn when th-e pull on it is reduced in the operation of the shuttle. This rubber elastic has long been a source oit serious criticism on the part of the weavers and ot the shuttle manufacturers, but its use still obtains, and no satisfactory substitute has gone into extended use.
The object ot the present invention is to produce an improved Vform of tension for shuttles, and the invention consists in the shuttle tension hereinafter described and particularly defined` in the claims.
In the accompanying drawings illustrating the preterred form ot the invention, Fig. 1 is a plan of the eye end of a silla shuttle embodying the present invention; Fig. 2 is a rear ele-v vation ot this portion of the shuttle; Fig. 3 is a horizontal section showing the shuttle tension and controlling means; Fig. 4iis a front elevation ot this end oi the shuttle; and Fig. 5 illustrates modification.
The illustrated embodiment of the invention is described as follows: The shuttle body carries the usual bobbin 11 in the bobbin recess 12. From the bobbin the yarn 13 extends through the eye 14- to the pin 15, and thence through the eye 16 of the tension lever 17, trom which it passes over the successive pins 18 and through the remaining eyes 19 of the tension lever. The tension lever 1'? is pivoted on the screw 20, and provided with a short spring-pressed arm 21, which embraces the spring-carrying rod 22. This spring-carrying rod is supported in the posts 23 and 241. The pin 24 is provided with a plain hole to receive the spring rod 22. The pin 23 is similarly provided with a plain hole, but it is also provided with a longitudinal hole which receives a screw 25 by means of which the position of the spring rod 22 may be fixed. Secured on the spring rod 22 is ,the spring button 2 tor the spring 27, which The pressure exerted by the spring 27 on the spring arm 21 of the tension lever tends to turn the tension lever into the position shown in F ig. 3, thereby forming a series oi' bights inthe yarn 13 being discharged from the shuttle. When a greater tension is applied to the yarn, the tension lever will be turned, drawing the eye arm up toward the row of pins 15, 18, and thereby moving the spring arm 21 ot' the lever in the direction to compress the spring 27. With som-e threads it is necessary to apply a greater spring pressure to the tension arm than with others, and this is readily accomplished by loosening the screw 25 and moving the spring rod 22 in one direction or the other-to the right, as viewed in 3, to reduce the tension on the thread, and to the lett to increase it. After the spring rod has been moved to the desir-ed position, the set screw 25 is screwed down and the spring is ield in its adjusted position.
f t is to be observed that this construction is simple in torni, and is made ot durable material. The eye portion of the spring arm 21` is made elongated so that the turning of the tension lever does not cause any binding ot the arm on the spring rod 22. The spring 27, being a compression spring, is a durable form of spring` and is preferred to a tension spring for that reason. Moreover, the use of this durable construction eliminates a great waste of time in replacing broken rubber elastics in the ordinary form of tension lever heretofore employed. The construction is simple and easily assembled.
In assembling the device the spring rod receives the spring and the Washer, and the right-hand end of the spring rod, as viewed in Fig. 3, is thrust into the opening in the shuttle by inserting it above the pin 211, and thrusting out toward the tip in a generally inclined position toward the tip of the shuttle, and moving out in that direction until of the springarm 21 of the lever, at which time the spring rod 22 is moved upwardly,
as viewedv in Fig. 3, until it is'laid into the open end of the loop formed in the lower end of the spring arm. Then the spring rod is moved in the opposite direction., and its end y .CII
i rod 22.
is inserted in the hole in the post 23. It is carried in this direction into the recess 30, whereupon the rod is moved until the righthand end is caused to enter the hole in the pin 24. The pressure of the spring against the spring arm of the tension lever Will now move the rod to the right, as viewed in Fig. 3, and the parts Will be assembled in place ready for adjustment to secure the desired tension to be applied to 'the tension lever.
F ig. 5 illustrates a modilication wherein the posts 31 and 32 replace the posts 23 and Q/l, and the rod 33 is used in place of the This spring rod 33 is received in holes in the posts 3l and 32y as in the other iorm, but its adjustment longitudinally is secured by screw-threading either one end or the other and providing it With set nuts 34 and 35. VJ here nicety offadjustrnent is desired this modification may be used. general, however, the cheapness of the other construction and the celerity with which adjustment of the spring tension may he made render its use preferable. Other constructions may be employed Within the scope of the claims.
Having thus described the invention, What is claimed is:
1. A shuttle provided with a tension lever pivoted in a recess therein, said tension lever having an eye arm and a spring arm,
a spring rod supported in the shuttle and Inl provided with a button, a compression spring on the spring rod engaging the spring arm at one end and the button at the other end, and means for securing the spring rod in position in the shuttle.
2. A shuttle having a spring lever tension device, consisting of a tension lever pivoted in the shuttle provided With an eye arm and a spring arm, a spring rod provided .With a button, posts supported in the shuttie provided With holes to receive the spring rod, one of said posts being provided With a set screw for securing the spring rod in adjusted position in the posts, a compression spring embracing the spring rod and engagino; the spring arm of the tension at one end and the button fixed on the spring rod at the other end.
3. A shuttle having a spring lever tension device comprising a tension lever pivoted in the shuttle, having an eye arm and a spring arm, the spring arm having an open-sided eye, a spring rod received in the open-sided eye of the spring arm, means for supporting the spring rod having provision for ad- `iusting it, and a compression spring on the spring rod ior applying pressure to the spring arm of the tension lever.
In testimony whereof I have signed my name to this specification.
