TUBE-HOLDER FOR LOOM-SHUTTLES.

Specification of Letters Patent.

Patent-ed Nov. 11,1919.

Application filed December 6, 1918. Serial No. 265,525.

To all whom t may concern: y

Be it known that I, GEORGE HENRY Lovrr'r, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Tube- Holders for Loom-Shuttles, of which the following is a specification.

My invention has reference to an improvement in loom shuttles and more particularly to an improvement in tube holders for loom shuttles.

Tube holders are secured to or form a part of the shuttle spindle and are adapted to detachably secure the tube on the spindle. Such tube holders must firmly and positively secure the tube to the spindle and if detachable, `they must be rigidly secured in place on the spindle, so as not to become loosened, in the operation of the shuttle. As heretofore constructed these tube holders have various defects, such as splitting the tubes and breaking the silk or yarn on the tubes, failure to hold the tubes on the spindles and weakening the spindle in constructing the tube holder on the spindle, thereby causing breakage of the spindles and they are comparatively costly to manufacture.

The object of my invention is to improve the construction of a tube holder for loom shuttles whereby, the above undesirable features are eliminated and a more perfect tube holder for loom shuttles produced, than has heretofore been done.

My invention consists in the peculiar and novel construction of a tube holder for loom shuttles, said tube holder having details of construction, as will be more fully set forth hereinafter, and claimed.

Figure 1 is a face view of the spindle end of a loom shuttle, showing the eye end of the shuttle broken away and the spindle provided with my improved tube holder, with the tube indicated in broken lines.

Fig. 2 is a longitudinal sectional view through the shuttle and tube holder, taken on line 2.2 of Fig. 1.

Fig. 3 is a transverse sectional view through the shuttle and tube holder, taken on line 3.3 of Fig. 1, and

Fig. 4: is a side view of the tube holder removed from the spindle.

In the drawing 5 indicates a loom shuttle having the usual spindle 6 provided with my improved tube holder 7 and 8 a tube, indicated in broken lines. The shuttle 5 spindle 6 and tube 8 are of the usual construction, as shown.

My improved tube holder 7 is constructed to have an externally screw-threaded tapered bod-y 9on the larger end of which is a collar- 10 having the oppositely disposed flattened portions 11.11, the oppositely disposed radial screw-threaded holes 12.12 eX- ten'zling in from the flattened portions and' a slightly tapered central bore 13 which eX- tends lengthwise through the holder and its the spindle 6, adjacent the pivot end of the spindle, as shown in Fig. 2L A screw 11 is screw-threaded through each screwthreaded hole 12 and has an inner slightly pointed end 15 which enters a nick 16 in the spindle 6 and a lock-nut 17 on the screw 14 engaging with a flattened portion 11 locks the screw in the tightened position, as shown in Fig. 3.

When in use the tube holder is firmly and positively secured to the shuttle spindle by the screws 14.14 and the screws locked by the lock-nuts 17.17, thereby preventing loosening of the screws and tube holder. The tubes being made of paper or a comparatively soft fibrous material, are screwed onto the screw-threaded tapered body 9 of the tube holder, as indicated in broken lines in Figs. 1 and 2', thereby firmly and positively securing the tube to the spindle, without injury to the tube, or to the thread on the tube, as the tube is secured at its larger end and not in its center, as heretofore.

As the principal element for securing the tube is the externally screw-threaded tapered body 9, it is evident that this tube securing element could be formed integral with the shuttle spindle, adjacent the pivot end of the spindle, and accomplish the same results as the detachable form shown, and at less cost to manufacture the tube holder.

Having thus described my invention I claim, as new :n

1. In a loom shuttle, a spindle pivotally secured at one end in the shuttle, a tube, a detachable tube holder consisting of an eX- ternally screw-threaded tapered member having a collar and a tapered bore fitting the spindle adjacent the pivot end of the spindle and means in the collar for detachably securing the tube holder to the spindle, whereby the tube is secured in place by screwing the larger end of the tube onto the tube holder.

2. A tube holder for loom shuttles, comprising an externally screw-'threaded tapered bodyhaving a collar and a tapered bore adapted to lit a Vloom shuttle spindle adjacent its pivot end, and lneansrin the collar adapted to detaohablyseou-re theftube holder to the spindle, whereby a tube is detaohably secured in @place tothe tube holder by `screwing the larger end ofthe tube onto ithesereW-tlneaded tapered body of vthe tube 10 holder.

3, A tube holder for looin shuttles, coniprising an externally screw-threaded ltaperedbody `9 having a collar 10 on its larger end, oppositely disposed flattened .portions 15 11.11 on the collar, oppositely disposed radial screw-threaded holes 12.12 in the collar and extending in from the Hattened portions, 'a slightly tapered longitudinal contralhbore 13 adapted to lit a loom shuttle spindle adjacent its pivot end, a screw 14 in each of the screw-threaded holes 12.12 in the -oollar and having a slightly pointed end 15 GEORGE HENRY LOVITT.
