H. M. PEDERSEN SAFETYPIN Filed Aug. 25, 1943 Inventor HWM M. Pdersw Patented July 11, 1944 UNITED STATES PATENT OFFICE SAFETY PIN Harold M. Pedersen, Forest Hills, N. Y.

Application August 25, 1943, Serial No. 499,959

3 Claims.

This invention relates to new and useful improvements in pins for holding clothes and other items together and more particularly to a safety An important object of the present invention is to provide a safety pin which is much less liable to come apart than the present-day safety pins in general use.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawing:

Figure 1 represents a side elevational view of the safety pin.

Figure 2 is an elevation looking at the opposite side from that shown in Figure 1.

Figure 3 is a cross section on the line 3--3 of Figure 1.

Referring to the drawing wherein like numerals designate like parts, it can be seen that the pin includes an elongated spring wire A bent to form a coil 5 at its intermediate portion where clips 6 are employed for holding the coil intact. The end portions 1, 8 of this wire member serve to define the pin back member and the pointed pin proper.

Numeral 9 denotes a head structure in the form of a hood constructed of sheet metal, this hood 9 being rolled at its edge portion as at Hi over the adjacent curved end portion of the back I. The hood 9 has a single side wall I l and this is formed with an opening to receive the bent backwardly disposed end portion 12 of a tongue l3 which extends downwardly from the rolled portion 10.

Extending upwardly from the lower port on of the wall ll is a spring lever l4, one edge portion of which is cut away to define a lug l5 which projects inwardly and has its lower end notched as at IS. The upper or free end of the lever I4 is curved as at H and normally bears against the upper portion of the edge roll of the hood 9.

It can now be seen, that in order to place the pin 8 in the position shown in Figure 1, the lever I4 must be swung outwardly so as to permit the pin 8 to by-pass the lug I5. When the p n 8 assumes the position shown in Figure 1, there is no way in which the pin can become displaced, inasmuch as the lug I5 is closely overlapping the tongue l3 and completely blockin any possible passageway for the pin 8.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. A safety pin including a head having a platelike wall closing one side thereof and provided with a rolled edge forming a socket at one side edge portion of the head, a wire member embodying a rigid back portion having its end curved and secured in the rolled edge at the other side edge portion of the head, said wire member further embodying a flexible resilient pin memher having a pointed end portion insertible in said socket, a rigid tongue projecting from the rolled edge of the head where the back portion is secured therein and extending crosswise of the head toward said socket, the end of said tongue contacting said side wall, and a spring tongue lever projecting from the rolled edge of the head at said socket and extending crosswise of the head toward and past the rolled edge where the back portion is secured therein, said spring tongue lever being disposed outwardly of said rigid tongue and having an inwardly projecting rigid lug intermediate its ends normally extending past the rigid tongue at one side of the latter, said lug being movable away from the rigid tongue upon manually springing the spring tongue lever outwardly to permit passage of the pin member from the socket for complete disengagement from the head.

2. A safety pin including a head having a platelike wall closing one side thereof and provided with a rolled edge forming a socket at one side edge portion of the head, a wire member embodying a rigid back portion having its end curved and secured in the rolled edge at the other side edge portion of the head, said wire member further embodying a flexible resilient pin member having a pointed end portion insertible in said socket, a rigid tongue projecting from the rolled edge of the head where the back portion is secured therein and extending crosswise of the head toward said socket, the end of said tongue contacting said side wall, and a spring tongue lever projecting from the rolled edge of the head at said socket and extending crosswise of the head toward and past the rolled edge where the back portion is secured therein, said spring tongue lever being disposed outwardly of said rigid tongue and having an inwardly projecting rigid lug intermediate its ends normally extending past the rigid tongue at one side of the latter, said lug being movable away from the rigid tongue upon manually springing the spring tongue lever outwardly to permit passage of the pin member from the socket for complete disengagement from the head, said end of the tongue being extended through the side wall and bent to secure the tongue to said side wall.

3. A device as defined in claim 1, wherein said lug has a notch in its lower edge to positively prevent complete outward passage of the pin memher until the spring tongue lever is manually sprung outwardly, and wherein said lug has an inclined upper edge to permit forcing of the pin member past the same toward the socket without manual operation of the spring tongue lever.
