CHARLES L. SPENCER, OF PROVIDENCE, RHODE ISLAND.

IMPROVEMENT IN NEEDLE-THREADERS.`

Specication forming part of Letters Patent N0. 58,314, dated September 25, 1866.

To all whom 'it may concern:

Be it known that I, CHAELEs L. SPENcEE, of the city and county of Providence, in the State of Rhode Island, have 4invented a new and Improved Machine forThreadin g Needles; and I do hereby declare that the following specification, taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof.

Figure 1 is a perspective view with aneedle threaded. Fig. 2 is a perspective view with the cap or cover thrown open, showing the mannerthe needle is removed. Figs. 3, 4, 5, 6, 7, 8, 9, and l0 are detailed parts. Figs. 1], 12, and 13 is another form of making a needlethreader, coming apart in two halves to remove the needle, and held together by two pins when in use. The principle being the same, I shall not endeavor to describe lnore minutely.

In lheaccompanying drawings, A, Figs. l, 2, and 3 is a tube for the purpose of guiding the needle to be threaded, one side of this tube is atteued and filed beveling. The hollow or needle-channel is partially filed O' at the upper end, as shown in Fig. 3.

C, Fig. 4, is a dat spring made of any hard metal. b, Fig. 3, is a small pivot for fastening spring O to the flattened surface of A.

At the upper end of the tube A is a projection, D, Fig. 3, and upon its top surface is a tapered channel running to, and the small end of taper intersecting, the needle-channel, as shown in Fig. 7.

E, Fig. 5, is a cap or cover nicely fitted to the surface of projectionD, and fastened by a hinge. This cap or cover has a tapered channel to match projection D, for the purpose of guiding the thread to the needles eye when in use, as shown in Fig 8. At the small end of taper on cap or cover E is a ridge or stop, F, Fig. 5, for the purpose of stopping the needle when its eye covers the small tapered hole that guides the thread, as shown in Fig. l.

Fig. 6 is a small piece of wire for holding the hinge together.

Fig. 9 is an end View of tube A, showing the entrance for the needle to be threaded.

Spring C is fastened to the tube A in such a manner that when the needle is pressed eye iirst through the channel the flat part of the needle comesi'n contact with spring, and is guided so the needles eye is always brought in the right position to receive the thread.

The advantage of my invention over all other needle-threaders s, that the needle can be threaded at any and all times while one end of the thread is fastened to the work. As the thread is set free from the threader by opening the cap or cover, the needle then can be removed at the opposite end from that at which it is entered. In all others the needle must be removed at the same end of threader at which it is entered, thus drawing the thread through the needle-channel, which would be impossible to do if the opposite end of the thread was fastened to any kind of work.

I do not claim the spring as an improvement in needle-threaders; but
