THREAD-GUIDE FOR SHUTTLES.

Specification of Letters Patent.

Patented Uct. 29,1918.

Application filed January 25, 1918. S eria1No. 213,762.

To all whom it may concern:

Be it known that I, FREEMAN CASS, a citizen of the United States, residing at Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Thread-Guides for Shuttles, of which the following is a specification.

The'present invention relates to improveguiding eyes for loom shuttles and particularly is an improvement upon a device for this purpose of the type or general character illustrated patent to J. R. Mitchell, No. 1,188,005, dated June 20, 1916.

The object of the present invention is to provide a thread tension or guiding eye. having a bodyof porcelain, or similar matemetal cap or holder, which may be readily connected with or detached from the poroe secure the same properly in the shuttle.

In the accompanying drawings Figure 1 isa plan view of a portion of a loom shuttle provided with a thread guide embodying the invention;

Fig. 2 is a sectional view, on the line 2-2 of Fig. 1;

Fig. 3 is a longitudinal sectional view through the thread guide, detached from the shuttle;

Fig. 4 is an end view of the guide;

Fig. 5 is a sectional view, on the line 5-5' of Fig. 3, drawn to an enlarged scale;

.Fig. 6 illustrates a slightly modified form of the cap or head.

Fig. 7 is a perspective view of the device shown in Fig. 6; and Fig. 8 is a detail sectional view.

Referring to the drawing A designates the loom shuttle, provided with the slots and openings commonly used in self threading shuttles and in which is-suitably positioned.

the thread tension and guiding eye constituting the present invention.

This, as shown, comprises a body, B, of any suitable vitreous material, such as porcelain, glass, etc., hereinafter referred to as porcelain, and a metal head or cap, (1, which'is detachably connected to the body and provided with means for engaging the shuttle to retain the guide in properposition therein. The body B is provided with the usual slots and eyes including the thread rer1al, for contact with the thread, with a.

ceiving opening, 6, and as shown the cap or head, C, receives the end of the body which is solid and does not extend beyond the said opening 6.

The cap or head, C, is held from relative rotary movement on the porcelain body by means on its inner surface engaging said body, as by forming a rib or lug C on the interior of the cap which fits within a suitably formed recess or groove in the body B. The cap and body are further united, and held from separation, by a screw D, or equivalent fastening means, so that the two form a unitary structure which can be readily fitted to or removed from the shuttle A.

Exteri0rly the cap or head C is provided with means for engaging the body of the shuttle and holding the guiding eye-in position therein. In the form of the invention illustrated in Figs. 1 to 5 this means consists of a rib or lug c which is adapted to enter a suitable groove or socket in the shuttle to hold the guiding eye from rotation therein.

As shown in Figs. 6 and 7 the metal head or cap member G of the guiding eye may be provided with a plurality of exterior ribs or lugs, E, to increase the extent of engagement between it and the shuttle.

The manner of using the improvements and the advantages thereof will be readily apparent.

It will be seen that the invention provides a thread guiding eye in which the thread contacting body is of porcelain, which material has been found most suitable for such purpose, while the shuttle engaging portion is of metal so that it will accommodate itself to contraction of the wood of the shuttle, Without causing breakage of the porcelain body. Further the cap or head can be readily removed and a new one substituted, or the same cap or head may be used successively with a plurality of porcelain bodies.

Instead of employing a screw D to con nect the metal cap or head with thebody B a pin or other equivalent securing means may be employed, as shown in Fig. 8.

Having thus described the invention, what is claimed and desired to be secured by Let ters Patent is 1. A thread guiding bushing for a shuttle comprising a porcelain body, a metal head fitted on one end of the body and provided with an exterior rib adapted to engage the shuttle to prevent rotation therein of the ment by an interlocking rib and groove and bushing, and means connecting the head and said head being exteriorly provided with body to prevent separation thereof. means for engaging a shuttle, and means for 10 2. A thread guiding bushing for a shuttle securing the head to the body to prevent 5 comprising a porcelain body, a metal head separation thereof.

fitted to one end of the body, the head and In testimony whereof I aflix my signature. body being held from relative rotary move- FREEMAN CASS,
