HUDSON W. HAKI ES, 0F. MILLBUBY, MASSACHUSETTS, ASSIGNOR TO WALTER C.

LOOlVI-SHUTTLE.

Specification of Letters Patent.

Patented June '7, 1921.

Application filed April 27, 1918. Serial No. 231,063.

T 0 all whom it may concern:

Be it known that I, Henson W. HAKES, a citizen of the United States, residing at Millbury, in the county of Worcester and State of Massachusetts, have invented a new and useful Loom-Shuttle, of which the following is a specification.

This invention relates to a loom shuttle and particularly to bobbin holding devices therein.

In automatic weft replenishing looms it is common to replenish the weft by forcing a fresh bobbin downward into the shuttle, thereby displacing an exhausted bobbin. The bobbins are each provided with a plurality of rings around their butts, and are held in the shuttle by grooved steel springs which engage these rings. These springs are subjected to heavy blows and to repeated jars and vibrations.

It is the general object of my present invention to improve the construction of devices for holding these springs in position in the shuttle body, so that the spring and all parts associated therewith may be rigidly secured and retained in position.

With this general object in view, my invention consists in certain arrangements and combinations of parts hereinafter described and more fully pointed out in the appended claim.

A preferred form of my invention is shown in the drawings, in which- Figure 1 is a plan view of a shuttle having my invention embodied therein;

ig. 2 is a longitudinal sectional elevation of the parts shown in Fig. 1;

Fig. 3 is a transverse sectional elevation taken along the line 3-3 in Fig. 2;

Fig. 4 is a plan view of the bobbin-holding spring and spacing block;

Fig. 5 is a side elevation of the parts shown in Fig. 4;

Fig. 6 is a perspective view of the springholding plate, and V Fig. 7 is a perspective view of the spacing2 block.

eferring to the drawings, I have indicated a shuttle 10 and a bobbin 11 provided with rings 12 which are held in grooves 13 in a two-armed bobbin-holding spring 14.

This spring is preferably formed from a single piece of flat steel bent to the outline shown in Fig. 4. The grooves 13 are milled in the inner face of each arm and the upper edges of the spring are beveled at 15 (Fig. 3) to more readily admit the bobbin.

Preferably this bevel is continuous for the entire length of the spring and is formed in the operation of rolling the steel, thus eliminating the expense of milling the edges of each spring.

A spacing block 16 is closely fitted between the arms of the spring 14, and the spring and block are perforated for a screw 17 by which they are secured in the shuttle. A retainer 18 is passed around the spring 14 and is secured at one end to the shuttle 10 by a screw 19. The retainer 18 is provided with an inclined portion 20 which assists in guiding the bobbin to its correct position between the arms of the spring 14.

A spring-holding plate 21 is interposed between the upper edge of the spring 14 and the retainer 18. This plate has extensions 22 on both sides which extend forwardly over the edges of the spring 14 and assist materially in securing the spring in position. The body portion of the plate 21 is provided with an opening 23 (Fig. 6) through which extends the projecting upper end of the spacing block 16.

With this construction, the parts are all held together in a peculiarly rigid and immovable condition, and displacement of any part is rendered practically impossible. In particular, the extension of the spacing block 16 through the opening in the plate 21 absolutely prevents change in relative position between the plate 21 and the spring 14 which is secured in position by said plate.

Having thus described my invention, it will be evident that changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in the claim, and I do not wish to be otherwise limited to the details herein disclosed, but what I claim is- In a loom shuttle, a two-armed bobbinholding spring, a bobbin-guiding retainer inclosing said spring, a spring-holding plate interposed between the upper edge of said spring and said retainer, said plate having a body portion and branched side portions extending forwardly to engage the arms of said spring and having an opening through its body portion a separate spacing block held in fixed position between tne sides of said spring, said block extending above said spring and fitting into said opening to po sition said plate and to positively prevent longitudinal or transverse movement of said plate relative to said block, and means to 10 hold said parts in operative relation in said shuttle.

fixed my signature.
