LOOIVl-SHUTTLE. V

SPECIFICATION forming part of Letters Patent No. 688,778, dated December 10,, 1901.

Application filed October 4, 1901.

To. all whom it may concern.-

Be it known that I, HENRY I. HARRIMAN, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented a-certain new and which the following is a specification, refer? ence being had therein to the accompanying drawings.

The invention relates to loom-shuttles of the well-known class having threading arrangements comprising, essentially, open or slotted yarn-delivery eyes or educts and passages or guides enabling the weft-yarn drawn from the yarn-containing cavities of the shuttles to find its way in the threading operation into the said yarn-delivery eyes or eduots.

The invention consists in a loom-shuttle of the class just referred to having threading arrangements which are constructed with especial reference to facilitating the threading operation and also to insure that in case it rises or jumps from the delivery-eye the weftyarn after once having been led into the same or in case in the threading operation it is led through the threading passage-ways substantially to the said deliveryeye without fairly entering the latter shall be prevented from escaping from the threading passageways and by the movements of the shuttle while in operation in a loom shall be caused to find its way into the delivery-eye in proper condition for Weaving.

I will now describe the invention with the aid of the accompanying drawings, in which latter I have illustrated the invention embodied in the best form thereof which I have yet devised.

In the said drawings, Figure 1 shows in elevation a portion of the length of a loom-shuttle containing the said embodiment of the invention. Fig. 2 shows the same in plan. Fig. 3 is a sectional view looking from the righthand side inFig. 2. Fig. 4 is a view showing the shuttle in a somewhat tilted position.

Having reference to the drawings, 1 designates the shuttle-body, 2 a portion of the shuttle-spindle, and 3 a portion of the yarn load upon the said shuttle-spindle.

4 is the usual yarn-passage, leading for- Serial No. 77,553. (No model.)

wardly from the main cavity of the shuttle, and 5 is the usual enlargement or chamber forming part of said yarn-passage. The enlargement or chamber 5 contains the guide post 6, around which the weft-yarn a changes its direction in traveling to the delivery eye or educt 7 in the side of the shuttle. The usual slot Sin the side of the shuttle-body extends upward from the said delivery eye or educt and is open at the top of the shuttle to permit the weft-yarn a to be carried downward through said slot into thedelivery eye or educt in threading the shuttle.

10 is the cover or threading-plate, which surmounts the post 6 and overlies the top of the slot Sin the side of the shuttle-body. As

usual, a sufficient space is left between the edge portions of the cover or threading-plate and the adjacent portion of the shuttle-body along through the threading passage-way 11 into or near the yarn-delivery eye or educt 7 from unthreading past the forward portion of the cover or threading-plate-i. e., being allowed to make a retrograde movement along the passage-way 11 past the forward portion of the cover or threading-plate-the said forward portion is furnished with a baffle-hook 14, extending laterally from the same, the free extremity of the said baffle-hook being shielded behind a transversely-extending baffleshoulder 15, with which the shuttle-body is formed or provided. The baffle-hook 14 is recurved, and the hollow the reofconstitutes a yarn-receiving pocket 16. Should the weftyarn rise or jump from the delivery eye or educt through slot 8 after having once been led into the said delivery eye or educt, or

should the weft-yarn in the performance of I00 the threading operation, have not been led completely into the said delivery eye or slot,-

any retrograde movement of the weft-yarn along passage-way 11 will be prevented from continuing beyond the baffle-hook 14. The Weft-yarn will be deflected by the baffle-shoulder 15 during such retrograde movement into the yarn-receiving pocket 16 inthe hollow of the hook and will simply draw through the hollow of the hook until when the yarn is impelled or drawn toward the delivery eye or educt 7 again, as by the hand of the weaver or the movements of the shuttle ina loom, it is caused to find its way into the said delivery eye or educt. To prevent engagement of the weft-yarn with the tip or free extremity of the hook 14 as the weft-yarn plays about in the hollow of the hook, the said tip or free extremity is depressed below the level of the adjacent surface of the shuttle-body, as indicated in the drawings.

The rear portion of the cover or threadingplate 10 is formed at the side along which the weft-yarn is drawn with a laterally-projecting point or angle 17. For the purpose of preventing aecidental escape of the weft-yarn after having been drawn under the said point or angle the shuttle-body is formed with a' laterally-extending pocket 18 to receive the point or angle, in which pocket the latter is sunk within the said pocket below the upper surface of the Wood of the side of the shuttle body. Thereby also the said point or angle is shielded from catching the warp=threads under which the shuttle moves in a loom.

esefrr I olaimas my invention-'- 1. In a loom-shuttle, in combination, the shuttle-body having the slotted or open yarndelivery eye and the baffle-shoulder forward of said eye, and the threading-plate having on its forward part the baffle-hook extending laterally behind said baffle shoulder and shielded thereby, and also having the yarn-receiving pocketin the hollow of the said hook, whereby unthreading past the hook is prevented, substantially as described.

,2. In a loom-shuttle, in combination, the shuttle-body having the slotted or open delivery-eye, and the threading-plate having at its forward part the transversely-extending baffle-hook with its free extremity shielded below the level of the surface of the adjacent portion of the shuttle, and the yarn-receiving pocket in the hollow of the said hook, substantially as described.

3. In a loom-shuttle, in combination, the shuttle-body having the open or slotted delivery-eye, and the threading-plate having at its forward part the substantially horizontal rccurved hook with shielded free extremity, and also having at its rear part the projecting point or angle shielded in a pocket provided in the shuttle-body, substantially as described.

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