SHUTTLE-PROTECTOR.

SPEGLFEGATION formingpart of Letters Patent No. 676,321, dated June 1 1, 1901.

. Application filed November 20,1900. Serial No. 37,162. (No model.)

To all whom it minty concern.-

Be itknown that I, JAMES JORDAN, a citizen of the United States, residing at Burlington, in the county of Chittenden and State of Vermont, have invented certain new and useful Improvements in Shuttle-Protectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in shuttle-box backs; and it pertains to a particular construction of the end of the back, whereby the wear and frequent destruction of the shuttle are prevented and the erratic movement of loose spindles is controlled.

My invention is particularly intended for use in connection with the Northrop loom, which uses a shuttle with a self-threader at one end thereof. Owing to the shape of the end of the shuttle-box back in this loom it is found in practice that when the shuttle in its movements along the race-plate catches in a dropped or loose thread or for any other reason is directed out of its course the point of the shuttle strikes the metallic end of the boX-back,with the result that the point of the shuttleis frequently broken or smashed, which absolutely destroys the shuttle for further use. WVhen the shuttle is not directed sufficiently from its course to cause the above result, the self-threader is liable to be worn by friction with the metal, and in a short time the shuttle must be put aside. In addition to this should the bobbin in the shuttle become loosened by not being properly pressed into its place or by the breaking of its spring it is liable to fly upward in its transfer and catch in and break the warp, so that in the actual running of said loom the life of the shuttle is Very short and the warp is seriously injured.

tion of the race-plate of the loom,- B my im: proved back for the shuttle-box, and O the shuttle-box plate.

My improvement consists in providing the end of the shuttle-box back with a yielding protector a, which is attached to the end of the top D of the shuttle-box back B and has its end 5 projecting downward below the inner face of the said top D and its end 0 curved, as shown, for the purpose of directing the shuttle downward or toward the bottom of thebox-plate 0. Its bottom extends down sufficiently far to form a shoulder S to-catch the end of the bobbin should it fly upward from the shuttle in its transfer from not being properly pressed down in its place in the shuttle or by reason of the breaking of its springs, so as to prevent its breaking through and materially injuring the warp.

This protector is composed of leather, rubber, or wood and may be attached in several ways to the end of the top D; but in either event it is made detachable, so that should it become injured by the contacttherewith of the metallic end of the shuttle or become worn it can be readily detached and another substituted therefor. By this construction of the top of the shuttle-box back the injury and Wear are mostly upon the protector, which is very cheap, as compared to the shuttle, and easilyreplacedbyanother. In actualpra-ctice it is found to avoid entirely the destruction of the end of theIshuttle and consequent incapacitation of the shuttle, and to greatly ina 1 5' Referring now to the drawings, A is a por i crease the life of the shuttle because of the de- I ner of attaching the protector, which is accomplished by providing the extremity of'the top of the shuttle-box with a longitudinallyextending slot or groove d, which is adapted to receive a tenon or projection upon the end of the protector. In this construction it will be noted that the protector projects below the inner face of the top of the shuttle-box to form the shoulder S to catch a flying bobbin and has its end curved for directing the shuttle down upon the box-plate O. The protector is preferably held within the slot cl through the medium ofscrews' e, which pass through the wall' of' the slot and into the protecton In Figs. 2 and 4 I show a slight modification in the shape of the protector and the manner of securing it to the top of the shuttle-box. In this instance the protector consists of a block I), having right-angle end and topfto fit into the L-shaped recess G, formed across the end of the top of the shuttle-box, while theo-uter or other end 0 is curved similar to the corresponding end of the protector (1, (shown in Figs. 1 and 3,) and it is also similar to said protector in that it has its under side projecting or'extending down below the inner face of the top of the shuttle-box to form thejshoulderS. The protectorin thisinstance serves the same purpose as the protector in Fig. land operates the same way to direct the shuttle down on the box-plate and to protect the shuttle from injury and wear and to catch the loosebobbin. The protector b is attached through the medium of the bolt H, which passes through the rear wall of the back of the box and through the block, as

illustrated, and by means of which the protector is-readily and quickly removable therefrom in case of injury or wear to be substituted bya new one.

Itwill be noted that in both constructions theend of the top of the shuttle-box is cut out and the protector inserted in the recess or whereby it isadapted to accomplish the pur- I poses-herein fully explained.

wall of the top, as shown, whereby it is more yielding than it would be if the metallic top extended entirely over the block or member.

While I have described my invention as inmake of loom where it would be advantageous for the purposes herein described.

Having thus described my invention, what "I claim, and desire to secure by Letters Patent, is-

1. A shuttle-box back having its top provided at the entrance end with a yielding ,1 block projecting downward below the inner face thereof and having its outer extremity curved upward at its under side, substantially as described.

2. A shuttle-box back having its top provided with a transversely-'arranged' recess, a yielding block detachably secured within the said recess, the under side of the block projecting downward below the face of the top and having its outer face curved upward, substantially as described.

3. A shuttle-box back havingat oneend a yielding block, the said block having its outer end extending beyond the outer end of the said top, substantially as described.

4. A shuttle-box back having its top projvided at one end with a yielding shuttle-protecting block, the said block having atits inner end a shoulder adapted to engage theend of the displaced bobbin, substantially as and for the purpose described.

5. A shuttle-box back having its top provided at one end with a yielding-'shuttle-pro- .tectin g block projecting downward below the inner face thereof, the inner end of the'block having a downwardly-projecting shoulder for the purpose of engaging the end ofa displaced bobbin, substantially as described.

6. A shuttle-box back having its top provided at one end with a yielding shuttle-protecting block, the outer end of the said block being curved upward and the inner end of l the said block having a downwardly-projecting shoulder for the purpose of engaging the end of a displaced bobbin, substantially as described. groove and pro ects below its inner face,

In testimony whereof I do affix my signature in presence of two Witnesses.
