IMPROVEMENT IN SHUTTLE-HOLDER.

The Schedule referred to :in these Letters Patent and making part of the same.

To all whom it 'may concern:

Be it known that I, CHARLES H. PAnnnNTnn, ot" Lowell, 4in the countyl of Middlesex, and State of Massachusetts, have invented new and useful Improvements'in Shuttle-Holders; and I do hereby decla-re that the-following is afull and exact description thercof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in providing a box, or receptacle for a shuttle, for the better security against damage to the same, and also more couvenie-nt to the user, during the operation of taking out andgputting in the shuttle, combining, in itself, cheapness, simplicity', novelty, and durability.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure 1 represents a plan of my improved shuttle- Y holder.

lFigure 2 represents a front elevation of the same, with a shuttle, as shown by red lines.

Figure 3 represents a side elevation of the same,

with parts broken out, showing the operation of the same.

Similar letters in the different figures indicate corresponding parts.

A represents a section, or a part of a loom, to which is secured my improved shittle-holder, by means of screws.

The shuttle-holder is cast in three pieces, b, c, and d, as shown in iig. l ofthe drawings, b representing .the righthand portion, or part of the bolder, and o, the lefthand, the sides of which are aringat the top, and contracted at the lower end.

rlhe sides correspond in shape with the shuttle. Their back parts are straight and smooth.

Nearly in the centre, on both of the sides band c, the ears d and e project, with the required bearings.

oel is the self-adjusting front-piece. Its bottom, or lower end, is curved inward, corresponding nearly in shape with the lower end of the sides b and c, nearA the centre of which, and cast to the same, is a suitable gudgeon, j', with journals at its extremities, which work in the bearings formed in the ears d Iand e.

The toprof this front-piece d is formed correspondingly in shape with the top of the side-pieces b and c.

Also, at the top, projecting from the'centre, is the catch-.hook g, which catches the shuttle in its descent, and on which the same is suspended.

It is a fact well known to manufacturers, that shuttles require much attention and care, to keep them free from roughness and bruises, so that they will pass and repass through the warp, without 'chang or breaking the same.

The usual way of keeping shuttles, when not in'use, is to hang them up on nails or pins. When this method is resorted to, the jar and vibrating of the loom will oftentimes throw them o, sometimes falling in the web, breaking the warp, at other times falling in the gearing of the loom, which is apt to result in the destruction of the shuttle, and great damage to the machinery.

Another common device used is a metallic, or iron box, cast in one piece,made so that the shuttle will it loosely, and,

into this box, the tip, by the weight of the shuttle, in

its descent strikes the bottom, so that, in a `very shortv time, the tips become bruised and damaged, to such an extentyt-hat it renders them unserviceable, and repairs necessary. Sometimes the bottom of this box is muttl'ed with leather or cloth, which is constantly giving trouble to the overseer.

W'ith my improved shuttle-holder, these several existing ditiiculties are eiectually remedied. The operator is enabled to deposit his shuttle in the holder without any damage, or injury in the least to any of its parts, as follows:

The shuttle is taken by the thread-delivery end, in a' vertical position, inserting the opposite end in the top of the holder, which is daring, or tunnelling on three sides, carelessly allowing the shuttle to descend in the holder, which iits loosely, in its descent. The nose of the shuttle comes in contact `with the inner bottom curvedpart of the frontfpiece d, pressing it outward. This operation carries the catch-hook g inward, by the front-piece al turning ou' the gudgeon f, until it catches the shuttle in the recessed delivery of the same, thus suspending the whole weight of the shuttle on the catch-hook g, relieving lthe bottom tip from striking or resting on any iron or metal of Iany kind, keeping the shut-tlesafe,and secure from falling,

and retaining the smoothness and perfect outside tinish, that are so essential to a perfect working-of the same, combining lightness in metal, cheapness in its manufacture, and finish, novelty, strength, durability, and beauty.

What I claim as 'my invention,and desire to secure by Letters Patent, is-

1. The self-adjusting front-piece d, with catch-hook y, for the purpose substantially as described and set forth.

2. A shuttle-holder, composed of three pieces, b, '0, and d, when arranged substantially as and for the purpose described.
