SPECIFICATION forming part of Letters Patent No. 788,733, dated May 2, 1905.

Application filed August 19, 1904. Serial No. 221,426.

To It whom it may concern:

Be it known that I, LOUIS O. SuNe, acitizen of the United States, residing at 348 West Jefferson street, Louisville, in the county of Jefferson, State of Kentucky, have invented certain new and useful Improvements in Clasp- Pins, of which the following is a speciiication.

This invention relates to clasp-pins, and more particularly to that class which employs an arm carrying a locking-catch and a pin pivoted to the arm and adapted to be held at its free end by the locking-catch.

It is an object of the present invention to provide an improved device of this kind which will automatically lock thefree end of the pin when the pin is pressed against the lockingcatch and will cause the pin to automatically move to open the device when thepin is freed from the locking-catch.

Other objects and advantages will appear in the following description and will be particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of the pin in a locked position. Fig. 2 is a bottom plan view of the pin. Fig. 3 is an end view showing the locking-catch. Fig. 4c is a perspective view of the pivoted member of the locking-catch. Fig. 5 is a section on the line 5 5, Fig. 3.

1 indicates the fixed arm of the device, and pivoted near one end at 2 is the pin 3, which has a tendency to remain open or at its free end away from the locking-catch, which will be hereinaftermore fully described. The pin 3 is caused to remain awayfrom the lockingcatch by means of a projection 1, thatengages with a portion of the arm 1 and limits the pins free movementtoward the locking-catch. The pin 3 is made of spring material, so that a further movement of the free end of the pin toward the locking-catch after being stopped by the projection 4 will cause the pin to be placed under tension. Of course any other means could be employed to normally hold the pin away from the locking-catch.

The locking-catch comprises a rigid or fixed member 5 and a pivoted member 6. The member 5 is provided near its point of at- 5 tachment to the bar 1 with two perforated and parallel ears 7, extending transversely of the bar 1, while the free end of the said member is provided with a guide-face 8, which directs the pin 3 between the two members of the catch. The member 6 is provided with two parallel and perforated ears 9, which are pivoted to the ears 7 of the rigid member by means of a bar 10, which extends longitudinally of the device. A spiral coil-spring 11 surrounds the bar 10, is secured at each end to one of the members of the catch, and is housed between the ears of both members to hold said members together. A curved arm 12 extends laterally from the pivoted member 6 and serves on its inner face 13 to hold the pin 3 to the catch and on its outer face 14 to assist in guiding the pin 3 to the juncture between the members formed by the end of the curved arm and the guide-face 8 of the fixed member. Projecting from the pivoted memher 6 is an operatingfinger-piece 15, by which the two catch members are separated to permit the pin 3 under tension to open.

To locl; the pin 3, it is pressed between the end of the arm 12 and the face 8, and to unlock said arm the linger-piece 15 is'moved, thereby moving the pivoted member 6, and the pin 3, having nothing to hold it and be ing under tension, springs away from the locking-catch.

It will be seen that I have provided a device in which the operating-spring is housed, the operation is entirely automatic, the parts are few and not liable to get out of order, and the operation is simple.

Having thus described my invention, wha I claim is 1. Adevice of the class described comprising an arm, a spring-pin pivoted at one end near an end of the arm, and a catch, near the other end of the arm, with which the free end of the pin is automatically interlocked when pressed thereagainst,comprising a fixed member having its free end provided with a guideface and a pair of ears near its other end; a pivoted member provided with a pair of cars pivoted on an axis longitudinal of the device to the ears on the fixed member, a laterally-projecting arm forming a hook on its inner face and a guide on its outer face, and a fingerpin extending longitudinally of the device and connecting the ears of the pivoted and fixed members, and a spiral spring surround- 5 ing the pin between the ears and housed by the members.

The foregoing specification signed this 16th day of August, 1904.
