Specification of Letters Patent. "Patented NO 30 192() Application filed August 20, 1919. Serial No. 318,689.

a very low cost and which is also simpleand positive in its action so as to enable easy and quick threading of the needle.

The invention is illustrated in the accom panying drawings in which:

Figure 1, is a side elevation:

Fig. 2, is an edge elevation:

F ig. 3, is a fragmentary detail perspective view of the threader point, and

Fig. l, is a similar view ofa modified form of threader point.

In proceeding in accordance with the present invention, a pair of similar oppositely disposed thin metal guide members 1, are employed. These plates are secured at their inner ends, as by rivets 2, on opposite sides of an interposed threader point 3, the latter being composed of a base 4 and a straight uniform cross sectioned shank 5 formed so as to readily pass through the eye of a needle. The point 8 isformed with a notch 6 forming a hook in. which the thread is caught. Eachmember 1, is formed with a longitudinal. slot 7 the slots being in register and being alined withthe interposed point 3 and shank 5. The slots form bifurcated outer ends for the guides l, the said outer ends of the latter beingtapered to a point and curved outwardly in diverging relation so as to facilitate'the entrance of the needle between the guides. V

In Fig. t the point is shown provided with a pair oi": thread abutments or notches forming a pair of hooks located onthe respective opposite sides of the point so that regardless of which side of the point the thread is passed along, same will be caught by or in one of the hooks.

In operation, the needle is first passed. be

is then passed through the slits 7 to engage the notch 6 following which the thread being held by the fingers the needle is moved along the point 3 and shank 5 and past the notch 6, which causes the thread to pass through the eye of the needle after which the needle is moved to release the thread from engagement with the device.

If desired a handle 8 may be provided, though this is not essential.

Sincethe guides 1, are similar and the shank 5 is interposed between same and secured by a. common fastening which holds the guldes in their operative relation, it will be apparent that the device can be economically produced and assembled. The thread it will also be noted is passed through the slots in a straight line and only for a short distance so as to catch in the notch 6, which provides an easy, simple and quick operation. The guides 1, function in a dual mannor, 2'. e. to guide the thread into the notch of shank 5 and to also guide the needle over the point 3 and shank 5. The guides being formed preferably of spring metal are yielding and embrace the needle therebetween with slight pressure so as to hold the latter in position relative to the device.

What is claimed is r 1. In a needle threader, a. pair of similar substantially flat and independent spring plates having their outer ends free and tapered in a somewhat 'V-shape and having alined longitudinal thread-receiving slots eX- tending therethrough, and a thread engag ing hook interposed between the plates and acting to space same apart, said thread hook being alined with the slots so that the thread can be moved into and through the slots and engaged with the hook, said slots allowing the thread to be extended through the slots and transversely over the outer faces of the plates, said plates being spaced along their adjacent side edges to allow the needle to be placed between the plates fron'i either side of the latter.

2. In a needle threader, a pair of similar substantially flat and independent spring plates having their outer ends free and ta pered in a somewhat V-shape and having alined longitudinal thread-receiving slots ex tending therethrough, a thread engaging hook interposed betweenthe plates'and acting to space same apart, said thread hook being alined with the slots so that the thread can be moved into and through the slots and engaged with the hook, said slots allowing the thread to be extended through the slots and transversely over the outer faces of the plates, said plates being spaced along their adjacent side edges to allow the needle to be placed between the plates from either side of the latter and fastening means passed through each of the plates and through the thread hook, each slot forming a pair of points at the outer end of the plate, the points of each plate being curved 10 outwardly and in diverging relation.

In testimony whereof I afiix my signature.

WILLIS C. HILL.
