SAFETY-PIN.

Specification of Letters Patent.

Patented Aug. 6, 1918.

Application filed February 15, 1915. Serial No. 8,135.

To all whom it may concern:

Be it known that I, HOWARD B. ROBINSON, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Safety-Pin, of which the following is a specification.

My invention relates to the devices above named, and an object of my invention, among others, is to provide a device of this class in which the pin point shall be securely held against accidental displacement.

One form of pin embodying my invention, and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which Figure 1 is a side View of a pin embodying my invention.

Fig. 2 is a view in section through the same on plane denoted by dotted line 22 of Fig. 1.

In the accompanying drawings the numeral 6 indicates the rigid branch of the pin, 7 the limber branch and 8 the spring coil which are made in a manner well known to pins of this class, the rigid branch 6 being secured within the head or shield 9 in any suitable manner. This head or shield 9 has a plate 10, preferably comprising an integral part. of the head, extending entirely across one side of the structure, and one edge of the shield is folded to provide a socket 11 for the reception of the point 12 of the limber branch 7 of the pin.

A holding tongue 14: projects into the socket 11 and is normally held in position to prevent the point 12 from disengagement from said socket, this tongue in fact constituting a bar that in its normal position absolutely prevents passage of the point 12 out of its socket.

This tongue 14 is formed as by means of slits extending from a point near the socket in which the rigid branch 6 of the pin is secured toward the socket 11, and the portion between these slits is forced inwardly and comprises the tongue. It has spring qualities suflicient to cause its free end to normally rest against the inner surface of the socket 11 opposite the plate 10. The point 12 of the pin being pressed against this tongue 14, the latter will yield to permit the point of the pin to pass into the socket 11 after which the tongue will immediately resume its normal position against the inner wall of the socket after the point of the pin has reached its seat, and the latter will thus be barred from removal from the socket, the distance between the end of the tongue 14: and the opposite wall of the socket 11 being suflicient to permit the end of the tongue to pass under the point of the pin. The tongue may be pressed inwardly to release the pin point and permit the latter to be removed from the socket 11.

While I have illustrated and described herein a satisfactory construction of device embodying my invention, this may be departed from to a greater or lesser extent and yet be within the spirit and intent of the invention.

I claim- A safety pin including a head having a plate closing one side of the head and with sockets formed in opposite edges of the head, a rigid branch having its end secured in one of said sockets, a limber branch insertible in the other of said sockets, and a resilient tongue formed by cutting slits crosswise of said plate to a point within the boundary of a lip of said socket for the limber branch, said tongue being pressed inwardly to resiliently engage the inner surface of said lip whereby insertion of the pointed end of the limber branch is permitted but accidental disengagement is prevented.
