LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 411,187, dated September 17, 1889.

Application filed May 31, 1889. Serial No. 312,690. (No model.)

To aZZ whom it may concern.-

Be it known that I, SUMNER A. DUDLEY, of Taunton, in the county of Bristol and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Loom-Shuttles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and the letters of reference marked thereon, forming a part of this specification, in whicl1- Figure 1 represents a top or plan view of a shuttle embracing my said improvements. Fig. 2 represents a bottom view of the shuttle shown in Fig.1. Fig. represents a side view of the shuttle with a portion broken away to show some of the parts more fully, as will be hereinafter more fully described; and Fig. 4 represents an illustrative shuttle, one side being broken away, as will be hereinafter described.

To enable those skilled in the art to which my invention belongs to make and use the same, I will now describe my said invention more in detail.

In the drawings, the complete shuttle-body is marked A, having the spindle B, the screw end B being screwed into the base-piece K of the slinttle-body,while the front B'of the spindle is made short and with a split in the center, the split parts forming an expanding spring to hold the bobbinO more securely. Bobbin C is provided with an opening D to receive the spindle when the yarn is spun and wound thereon.

Spindle B is stiff and rigid and does not turn out when the bobbin of yarn is to be placed thereon or the empty bobbin 0 is removed therefrom. The base C of bobbin C has a groove C out therein to receive the catch ends G G of the bobbin-holding catches F F, which are secured in their respective slots cut in the shuttle by pins II II, while a spiral spring I is compressed between the rear ends E E of the bobbin-holding catches F F, as fully shown in the drawings. Spring I fits in a hole bored in the wood part K of the shuttle. Consequently one end of said spring presses out the end E of the bobbin-holding device F G, and the other end of the spring I presses out the end E of the bobbin-holding device F G, and by the combined action of the said bobbin-holding devices the bobbin is held secure, and that, too, in a central position in the shuttle, and as a result the yarn is drawn oif the bobbin C and through the eyeLof the shuttle without liability to break by being caught on the front end of the bobbin, as is the case in shuttles when only a single bobbin-catch and holding device are used.

The operative can change from an empty to a full bobbin with my invention much quicker and in a more convenient manner than by the use of the old style of shuttle,in

.which a single catch is used, and the spindle is hinged and has to be turned out to remove the empty bobbin and put on a full one.

WVith my short rigid spindle the operative with the thumb and forefinger depresses the ends E and E, thereby lifting both catches G and G from the groove 0 when the bobbin 0 will slip from spindle B when the front end of shuttle A is depressed or held down, this operation being performed by one hand while with the other hand the operative holds the full bobbin ready to be slipped into place on spindle B, where it will be caught and held by the catches G G as soon as in place, and the ends E E are allowed to spring back into the position shown in Figs. 1, 2, and 3 of the drawings. As the bobbin is not turned or lifted out of its longitudinal position until after both catches are free from groove 0 the rear part of thebo'bbin-head is not liable to be split off,which is a great advantage and obviates the objections to the hinged spindle in common use. i

In Fig. 4 an illustrative shuttle, partly in section, is shown, in which the bobbin G is shown held by a single catch device F G, and the hole D inthe bobbin being worn large at the base or head 0. The bobbin end over which the thread is drawn cants to one side of spindle B. Consequently the yarn will break before it is all drawn off from the bottom part of the bobbin, a result that will not follow if my double catches are used.

It has become the practice to dampen the yarn 011 the bobbins in woolen-mills before using the filling in the Weaving operation. The result is that the bobbins become swollen and are often split by the long shuttle-spindle in common use, and to remedy this andother diiiiculties before mentioned I make the shuttle with a short spindle and combine with it and the shuttle two bobbin holding or catch devices, as before fully explained. As the spindle is short and is rigidly fixed in the base K of the shuttle-body by means of its screw end B it is not liable to break or get out of order. If preferred, a solid stem or spindle B may be employed, since with two bobbin-catch devices, as described, the bobbin is held well in position when either form of stem or spindle B is used.

Having described my improvements in shuttles what I claim therein as new and of myinvention isa 1. The combination, with shuttle-body A, of the short stiff spindle B, bobbin-holding catches E F G and E F G and spiral spring I, substantially as and for the purposes set forth.

2. The combination, with the base K of the shuttle, of the bobbin-holding catches E F G and E F G, and spiral spring I, said parts being constructed and relatively arranged for joint operation, substantially as and for the purposes set forth.
