PIN-FASTENING.

SPECIFICATION forming part of Letters Patent No. 485,005, dated October 25, 1892.

Application filed March 11, 1892. Serial No. 424,491. (No model.) Patented in Germany April 23, 1891, No. 59,146. and in Belgium April 25,1891,N0-94=,667-

T0 at whom it may concern.-

Be it known that I, THEODOR FAHRNER, a citizen of the Grand Dukedom of Baden, residing at Pforzheim, in Baden, and Empire of Germany, have invented certain new and useful Improvements in Pin-Fastenings, (for which I have obtained a patent in Germany, No. 59,146, dated April 23, 1891, and in Belgium,No.94,667,dated April25,189l,)of which the following is a specification.

This invention relates to a pin-fastening which is applicable generally to pins used in jewelery, such as scarf-pins,loutis also applicable to pins used for other purposes.

It consists in the various features of improvement more fully pointed outin the claim.

In the accompanying drawings, Figures 1 and 2 are rear and front elevations of a pin provided With myimprovement. Fig. 3 shows corresponding views of a modification.

The letter A represents a pin provided with a downwardly-curved guard B, made either in one piece with the pin, as in Figs. 1 and 2, or in a separate piece therefrom, as in Fig. 3. The guard B is so curved that it crosses the shank of the pin twice, so as to form an upper closed loop and a lower open loop. In

Figs. 1 and 2 the first crossing is effected by the intertwisted portion 0, while the lower crossing is effected by the spiral tipD of the guard. In Fig. 3 the upper crossing is single and takes place at the point C.

In use the pin is pushed into the scarf or other material up to the point C or C, with the spiral D lying in front of the pin-shank. After the pin is seated it is revolved through a semi-revolution, so that the spiral comes to lie back of the pin-shank, as shown in Fig. 2 and the right-hand side of Fig.3. This will iuterpose the spiral between pin-shank and the punctured part of the scarf and will effectively prevent the pin from being withdrawn. It will be necessary to turn the pin back into its original position before it can be removed. It will be seen that by crossing the pin and guard at the upper point the scarf can never slip up above such point and the head of the pin will therefore always remain properly exposed. Of course the guard B may be curved either to the right or left of the pin-shank, as may be desired.

What I claim is- A pin provided with a downwardly-curved guard that crosses the pin-shank twice to form an upper closed loop and a lower open loop, substantially as specified.

Signed at Stuttgart, \Viirtemberg, this 23d day of February, 1892.
