IMPROVEMENT IN LOOM-SHUTTLES.
Specification forming part of Letters Patent No. 186,674,
May 1,
To all whom it may concern.'
Be it known that I, ALBERT HALLOWELL, of Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented new and useful Improvements in Loom- Shuttles, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings.
My invention relates to self-threading devices 5 and consists in closing the threadingslot, as hereinafter described.
Figures l and 4 are plans of the delivery end of a shuttle; Fig. 2, a vertical longitudinal section of the same; Figs. 3 and 6, vertical cross-sections through the eye ofthe shuttle; and Fig. 5, a side view of a shuttle with a part broken away to show the internal mechanism. Figs. 1, 2, 3, and 6 show the best form of my invention.
A is the body of the shuttle. lie plug of the shape shown in Figs. 2 and 3, being a cylinder, D, surmounted by the frustum of an inverted cone, C. A cap-screw, E,v is screwed into the lower end of said plug, the head of the screw being larger than the cylinder D. A flange at the top of the plug, and a spiral spring, F, around the cylinder D, be-,. tween the head of the screw and the shoulder in the wood A, keeps the top of the plug dush with the top of the shuttle. On the side of the plug, nearest the eye H, is a wedge-shapedi piece, G, thickest at the top, and cast in one piece with said plug. The wedge G fills a slot cut from the top of the shuttle to the eye H. A slot, I, extends from the chamber "K to the plug. A wing, S, on the plug B preventsv the thread from catching between the cone C e shuttle.
' By pressing the screw upward, the plug is lifted, and the thread from the cop may be passed through the slot I, and on the farther side of the plug down through the wedgeshaped slot into the eye. On taking the finger from the screw, the plug and wedge fly down into place ush with the top and side of B is a metaldated January .30, 1877; application filed 1876.
represents a lever, pivthreading the shuttle. The adjacent edges of the arm G and the plate L are beveled to fit each other accurately.
By pressing on the left end of the lever the arm is raised, so as to leave a slight opening between said arm and the eye-plate, and the thread from the cop is then passed over the ear and plate down into the eye H. The lever, when released, springs down against the plate, and closes the opening between the arm and the eye-plate.
The lever, the plug and wedge, and the screw are all finished ush with the wooden body of the shuttle, so that there is nothing to catch the warp-threads when the shuttleis thrown in the loom. Instead of the screw E, a rivet, E', running through the plug B and headed on the top of the plug B, may be used, as shown in Fig. 6.
I claim as my inventionl. A loom-shuttle provided with a threading-slot capable of being opened and closed, as and for the purpose described.
2. A loom-shuttle provided with 'an automatically-closing threading-slot, as and for the purpose described.
3. The combination of the plug B, provided with the wedge G and the spring F, as and for the purpose described.
