LOOM-SHUTTLE.

SPECIFICATION forming` part of Letters Patent No. 407,871, dated July 30, 1889.

Application filed August 13, 1888. Serial No. 282,624. (No model.)

To all whom it may concern:

Be it known that I, GEORGE C. MOORE, a citizen of the United States, residing at Easthampton, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Loom-Shut- A tles, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of my invention is to provide a convenient shuttle adapted to carry a large cop of yarn and of such construction that the yarn may be drawn off under proper tension. I also provide my shuttle with a cop-holding spindle which is securely and rigidly held in place, but which can be quickly and conveniently removed and inserted when it is desired to place a new cop in the shuttle.

My shuttle is more particularly intended for use in narrow-ware looms-such as is shown and described by my application, Serial No. 282,625, iiled simultaneously herewithbut may be used for other purposes.

In the drawings, Figure 1 is a plan view of my improved shuttle. Fig. 2 is a bottom view of the same. Fig. S is a section on line 3 3, Fig. 1. Figs. 4, 5, and (i are detail views of the spindle and its locking-plate; and Fig. '7, a detail sectional elevation on line 7 '7, Fig. 1, looking in the direction of the arrow adjacent to said line. l

A denotes the body of the shuttle, the forwardly-proj ecting front part of which is provided at its center with a delivery-eye a.

B is the cop-holding spindle, and C is the cop. The spindle B is provided with a tang B', the upper part of which is notched to form a hook b, and the lower part of which forms a downwardly-extending projection b.

D is the locking-plate, by which the spindle is attached to the shuttle, said plate having a vertical recess d to receive the tang B of the spindle, and said recess being open to the front of said plate, excepting at the points where it is bridged by the upper and lower cross-bars d d2. When the spindle is in operative position, as shown by Fig. 3, it will be rigidly locked in place by the engagement of the hook b with the upper cross-bar d', the

downwardly-extending projection b being behind the lower cross-bar cl2. By lifting the spindle to the position indicated by Fig. 4. the hook b and projection h will be disengaged from the cross-bars d d2, so that the said spindle can be readily removed by turning up the forward end thereof and taking the tang out of the slot d.

The yarn from the cop passes through a guide-eye d near the end of the shuttle, thence through a tension device consisting, preferably, of two bow-springs e and f, held in place by a wire support g and a pin h, said pin passing through both of said springs, and serving, also, to keep the yarn, which runs below it and above one end of the said wire, from getting out of the tension device. The ends of the spring e are forked or notched to embrace the wire support g, as is also one end of the spring f. (See Fig. 7.) To vary the tension, the spring emay be removed and bent or straightened a little to cause it to press with more or less force on the yarn. If desired, the spring f may be omitted, in which case the yarn will run between the spring e and the inner wall of the shuttle. From the tension device the thread runs through the eye c' of a light take-up spring 7s, housed in a tube m, attached to the inner wall of the shuttle. The spring 7s is in the present instance removably secured in its tube by a plug n, which engages the tail end ot' the spring, as shown in Fig. 1, so that if the spring should break or lose its tension the plug can be taken out and the spring loe removed and replaced by a new one.

I prefer to use cops of yarn in my shuttles, as more yarn can thus be carried by the shuttles at one time than would be possible were quills or bobbins employed 5 but, owing to the rapid reciprocating movements of the shuttles, more or less slack yarn is apt to be drawn from the cops; and to prevent the looselyhanging slack yarn from dragging on the lower warps of the sheds I provide each of my shuttles with a bottom piece or floor a3. This bottom piece or iioor incloses the bottom of the shuttle, and as it shuts out more or less of the wind incidental to the motion of the It may here be observed that my improvedshuttle is capable of carrying about eight times as much yarn as is carried by the quills or bobbins of the shuttles heretofore usually employed in the looms for weaving elastic fabrics, and frequent stoppage of the loom for the purpose of supplying the shuttles with yarn is therefore avoided.

Having thus described my invention, l clailn and desire to secure by Letters Patentl. The combination, with the loom-shuttle body A, of the spindle B, having a tang B', provided with a hook b and a downwardlyextending projection b', and the locking-plate D, having the recess or slot cl, and the crossbars d and d?, bridging the front of said recess or slot, substantially as set forth.

2. The combination, with the loom-shuttle body A, of the wire support g, the tension bow-spring e, having notched or forked ends embracing said support, and the pin h, substantially as set forth.

3. The combination, with the loom-shuttle body A, of the tension device consisting of the wire support C, the bow-springs c and f, and the pin h, substantially as setforth.

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

GEORGE O. MOORE.
