R. v. FORD SAFETYPIN Filed April 24, "1955 INVENTOR. R0 BERT 1 FORD Patented May 4, 1937 SAFETYPIN Robert V- Ford, San Francisco, Calif. Application April 24, 1935, Serial No. 17,956

the spring portion 6, to hold the same on the pin 8 Claims.

This invention relates to a safety pin having a clasp head thereon to prevent the pin becoming unintentionally opened.

An object of the invention is to provide an improvedtype of safety pin which will securely hold and cannot be accidentally detached when in use. A still further object of the invention is to provide a safety pin that will be superior in point of simplicity, inexpensiveness' of construction, positiveness of operation, and facility and convenience in use and general efiiciency.

In this specification and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it maybe embodied in other forms; and it is also to. be understood that in and by the claims followingthe description, it is desired to cover the invention in whatsoever form it may be embodied.

I In the accompanying drawing:

a Fig. 1 represents aside elevation of a safety pin constructed in accordance with my invention, and showing the same in the closed position.

Fig. 2 is a side elevation of the pin with the .clasp portion removed therefrom. a I

Fig. 3 is a section taken through Fig. 1 on the line 33.

Fig. 4 is a side elevation of a pin in the closed position, and showing the clasp moved to a point where the pin may be either opened or closed.

In detail the construction illustrated in the drawing comprises a safety pin formed of two side members I and 2, connected at one end by a spring ring 3, said parts being preferably composed of spring wire. in the usual manner. The side member I is pointed at one end in the manner of an ordinary pin as shown at and the other side member 2, which constitutes the back of the pin and handle therefor, is provided at one end with a transverse loop or bend 5, a leg disposed at a slight angle to the member 2 and constitutes a spring portion 6, and the terminus 6'. The terminus of the spring portion ii lies substantially at right angles to the side members I and 2 and forms a guard to prevent accidental opening of the side member I when the pin is closed, except in the manner to be hereinafter described.

A clasp cowl or casing 8 is adapted to beconfined around the side member 2, and the loop 5, as well as the spring portion 5, said clasp 8 being of a flattened longitudinal shape and having opposite sides 9 thereof crimped or bent in under assembly. The forward is slotted as at I0, and the portion of the clasp II immediately below the slot ID, in vertical alignment with the pointed end of the side member I, to prevent dislodgement of the pin from said socket when the clasp 8 is in the closed position shown in Fig. 1.

The upper side of the side member 2 is either bent or formed with a projection I2 thereon, which lies within a recess or notch I3 on the upper side of the clasp 8. When the projection I2 registers with the notch I3, as shown in Fig. 1, then the pointed portion of the side member Imay not be opened or closed. In order to open the pin, the clasp 8 is moved axially outward on the side member 2 of the pin, by disengaging the projection I2 from the. notch I3, into the position shown in Fig. 4. The spring portion 6 of the side member 2 normally maintains the projection on the side member 2 in registry with the notch I3. Of course this position may be changed by moving the clasp 8 endwise on the pin, after overcoming the tension of the spring portion 6. The distance between the looped portion 5 of the side member 2 and the terminus 6 thereof, regulates the distance which the clasp 8 may slide on the pin when the clasp member moves from the closed position shown in Fig. 1 to the opened position shown in Fig. 4.

In operation the pointed portion of the pin is first opened by sliding the clasp into the position shown in Fig. 4, after which the pointed portion of the pin is passed through a garment or other article, in the usual manner and pressed down into the position shown in Fig. 4, after which the clasp 8 is moved into the closed position shown in Fig. 1. The pin is detached from the garment by reversing the sequence of operation heretofore described.

With my pin, it is impossible for the same to become accidentally opened, inasmuch as the clasp 8 cannot be moved except by a force suffie cient to overcome the tension of the slanted spring portion 6 of the side member 2, against the crimped portion 9 of the clasp, and to permit the disengagement of the notch I3 from the projection I2. The terminus 6 of the spring portion also functions as a guard which maintains the portion of the clasp 8 pointed end of the side member I in its socket a and holds the same against accidental dislodgement, as well as a guide for directing the pointed end of the side member I into the socket II.

Having thus described this invention, what I claim and desire to secure by Letters Patent is:

l. A safety pin comprised of two side parts having a spring connection at one end, one of said parts being pointed at an end thereof, and the other part being formed into an inwardly di- 5 rected loop and relatively straight leg in the same plane with the aforesaid side parts; and a clasp slidably confined on the side part having the loop and leg thereon and being adapted to receive the pointed end of the other side part therein, whereby in one position of the clasp the pointed end of the pin may be opened and in the other position said pointed end is held closed; a projection on one side part engaging a notch in the clasp for holding said clasp in a position against movement and thereby preventing the pointed end of the side part from being opened.

2. A safety pin comprised of two side parts having a spring connection at one end; one of said parts being pointed at an end thereof, and the other part being formed with a spring guide thereon in the same plane with the side parts; a clasp mounted on said spring guide for holding the side part having the pointed end in the closed position, said clasp being slidable whereby the pointed end of the side part may be disengaged therefrom and brought into the opened position; and a projection on one side part engaging a notch in the clasp for holding said clasp in a position against movement and thereby preventing the pointed end of the side part from being opened.
