Feb. 18, 1930. G. A. RUNKEL SHUTTLE HOOK Filed April 27, 1929 Grantfl.fluml?eggmm Gamma Patented Feb. 18, 1930 UNITED STATES GRANT A. RUNKEL, OF LANCASTER, PENNSYLVANIA SHUTTLE HOOK Application filed April 27, 1929'. Serial No. 358,580.

This invention aims to provide a tool for threading a shuttle, and particularly a shuttle in which a mass of wool or the like is used to get the desired tension on the thread, the

construction being such that the thread may be pulled through the wool by means of the tool, without dragging any of the wool away into the pot eye of the shuttle.

The invention aims to provide general improvements in a tool of the sort alluded to, and it will be understood that a mechanic who keeps within the scope of the claim can change the precise structure shown, without departing from the spirit of the invention.

Figure 1 is a longitudinal section of the shuttle into which the tool has been thrust; Figures 2 and 8 are elevations showing the hook portion of the tool; Figure 4 is a cross section on the line H of Figure 2.

My tool can be used in various ways, but I will illustrate one specific application of it. The numeral 1, therefore, marks a shuttle carrying a bobbin 2 on which the thread 3 is wound. The numeral 1 designates a partition carrying the pot eye 5, and behind the partition there is a recess 6 in which is mounted a mass of wool 7 or the like, held in a cloth casing 8, the wool being used to keep the proper tension on the thread that extends through the wool and through the pot eye 5. A good deal of trouble has been met with in using threading tools in a shuttle of this kind, because the hook on the tool that pulls the thread through the wool 7 and through the pot eye 5, will also pull away some of the wool: an operation which is undesirable for reasons readily understood by those skilled in the art.

The shuttle-threading tool forming the subject matter of this application comprises a rod 9 preferably made of flexible metal, but stiff enough to keep any shape to which ithas been bent by the application of considerable force at the fingers of an operator. At one end the rod 9 is provided with a handle 10. At its opposite end, the rod 9 is supplied with a longitudinal slot 11 having a flared lateral mouth 12 which opens through the side of the rod. The slot 11 and the mouth 12 define a hook 14 having a bill 15 extended longitudinally of the rod and set back as at 16 from the prolonged outer surface 17 of the rod. Owing to the construction of the hook 14, and because the rod is smooth and 'devoid of projections from the hook 1 1 to the handle 10, the rod may be thrust through the pot eye 5, the thread 3 may be engaged with the hook 14, and the tool may be operated to pull back the hook through the wool 7 without catching and tearing the wool or dragging any of the wool into the pot eye 5.

I claim:

A shuttle-threading tool comprising a rod provided at one end with a handle, and supplied at the opposite end with a longitudinal slot having a lateral mouth which opens through the side of the rod, the slot and the mouth defining a hook having a bill extended longitudinally of the rod and set back from the prolonged outer surface of the rod, the grid being smooth from the hook to the han- In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.

GRANT A. RUNKEL.
