IMPROVEMENT IN THIMBLES.

Specification forming part of Letters Patent No. 138,445, dated April 29, 1873; application filed February 17, 1873.

To all whom it may concern:

Be it known that I, WILLIAM P. SLENsBY, of the city, county, and State of New York, have invented an Improved N eedle-Threadin g Thimble, of which the following is a specification:

This invention relates to a new combination of thimble and needle-threader, when the latter is cast in one piece and provided with projecting rivets or pins, whereby it is attached to the thimble, and whereby the spring which is to retain the needle in the threader is also attached to the latter. The invention consists, first, in the combination of the cast B needle-threader with three projecting pins, of which two at one side serve to fasten the threader to the thimble, and one at the other side to hold the tension-spring in place. The invention also consists in perforating the thimble for the reception of the rivets on the threader.

By this manner of construction the connection of the two parts named is greatly simpli-. fied, and a firmer hold obtained than by the ordinary process of soldering.

In the accompanying drawing, Figure 1 represents a perspective view, showing the three parts-to wit: the thimble, the'threader, and the spring-detached. Fig. 2 is a longitudinal section of the threader, showing it applied to a thimble.

holds the needle in position in the threader, the said spring with its yielding end constituting part of one side of the needle-receptacle a, which is clearly shown in Fig. 2.

The spring 0 is attached to the threader B by means of a rivet, 6, formed on the latter. ff are two more rivets or projecting pins formed on the casting B for the purpose of fastening the same to the thimble A. The thimble is perforated, as at g g, for the reception of these pins f f, and has its rim or lower flange it cut out in line with" these apertures for accommodating the body of the threader By reference to Fig. 1 it will be observed that the pin 6 is on that face of the threader B which stands at right angles to that face of the same from which the pins f project.

For connecting the parts the spring 0 is I first riveted to the threader B by means of the pin 6, and the combined threader and spring are then riveted to the thimble, in the position indicated in Fig. 2, by fitting the pins f through the apertures g, and then upsetting or heading them within the thimble to secure the threader in place.

Claims.

l. The threader'B, cast with projecting rivets e and ff, substantially as herein shown and described.

2. The thimble A, perforated as shown at g g, substantially as and for the purpose specified.

3. The combination of the perforated thimble A with the cast threader B having the pins eff, and with the spring 0, all arranged for connection with each other in manner set forth.
