PIN-CLUTCH.
Specification of Letters Patent.
Patented Nov. 24, 1914.
Application led June 2, 1914. Serial No. 842,494.
To all whom t may concern Be it known that I, HARRIS LEVIN, a citi- Zen of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Pin-Clutches, of which the following is a. specification.
This invention relates to clutches for pins such as scarf pins, and has. in view the production of a device that is simple, eco nomical to make, reliable inuse, and which not only holds a pin securely, but from which a pin is released quickly and easily, as will now be explained, reference being had to the following specification andL claims, and the drawing, in which- Figure 1 is a longitudinal sectional view of the device, Fig. 2 is a similar view of the device with a pin inserted, Fig. 3 is top view of the holder 17, Fig. 4 is a section of the holder showing the position of the balls, Fig. 5 is a section of the holder showing the use of rollers instead of balls, Fig. 6 is an elevation showing a flat spring with a groove, attached to the hollow stem 12, and Fig. T is a perspective of the casing 17.
Referring to the drawing there is shown4 a casing 10, provided with a top or cover 11 and a bottom 19. Through the top 11 passes al hollow stem 12 having an enlarged por tion 13. To the hollow stem 12 are attached flat springs 15. These springs may either be in one piece forming a U as shown, or they may be attached separately. The enlai-ged portion 13 has preferably an internally expanded opening to facilitate the insertion of a pin 20. The hollow stem is kept under tension by means of the coiled spring 16. Below the stem 12 is located the holder 17 in which are held balls 18, or rollers 22, contacting with the springs 15 and holding a pin 20 securely after it has been inserted. The holder 17 may preferably be made of a single piece, as shown, in which are .made the incisions 14 and a perforation between these incisions tohold the balls 18 or the rollers 22. The flat springs 15 may have a central groove 21, if desired, to more firmly engage the balls 18, as shown in Fig. 6. The holder 17 is driven into the casing and is held secu-rely in place by friction. It has incisions 14 in which move the flat springs 15 and prevent them as well as the stem 12 from rotating.
Copies of this patent may be obtained for The operation of the device is as follows: Vhen a pin 20 is passed through the hollow stem 12 it forces the balls 18 or rollers 22 apart, at the same time causing them to revolve, whereby the springs 15 and the hollow stem 12 attached thereto are mov'edupward, the hollow stem being kept under tension so as to keep the balls 18 or rollers 22 in constant contact with the inner surfaces of flat springs 15. If an attempt be made to remove a pin from a scarf, the lenlarged end 13 of the hollow stem 12 will be forced against the fabric and by the pressure forces the springs 15 more firmly against the balls or rollers, whereby the pin is held in place very securely.
To remove a pin it is taken hold of by one hand, and the enlarged portion 13 is separated from the casing by the other. By the separation of the enlarged portion 13 from the casing, the springs 15 are elevated and their hold upon the balls 18 is diminished so that the pin is readily pulled out.
The device is most convenient both for p attachment and release, and not liable to get out of order. This device holds so firmly that it will break rather than release its hold. When rollers are used in place of balls plain flat springs are preferred. lVhen balls are used in the holder theflat springs may be either plain or grooved.
What l claim as new is:
1. 1n a safety clutch, a casing, revoluble members, a holder for the revoluble mem bers attached to lthe casing, a hollow stem carrying fiat springs contacting with the revoluble members, a spring holding the hollow stem under tension, the flat springs being prevented from turning by contact of said springs with said holder.
2. In a safety clutch, a casing, balls, a holder for the balls, a hollowstem carrying fiat grooved springs ,contacting with the balls, a spring holding the hollow stem under tension, the flat springs being prevented from turning by contact of said springs with said holder.
Signed at New York in the county of New York and State of New York this 29th day of May, A. D. 1914.
