SAFETY-PIN.

SPECIFICATION forming part of Letters Patent No. 784,968, dated March 14, 1905.

Application filed April 16,1904. Serial No. 203,257.

To (all 1071/0111, it 'lll/fl/j/ concern.-

Be it known that I, AsA W. STRAIGHT, a citi- Zen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Safety-Pins; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has general reference to improvements in safety-pins; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described and then pointed out in the claim.

In the drawings already referred to, which serve to illustrate this invention more fully, Figure 1 is a perspective view of' this improved safety-pin. Fig. 2 is a plan of the same. Fig. 3 is an inverted plan, a portion of the plate being broken away to illustrate the construction of this device more clearly. Fig. 4 is a longitudinal sectional elevation in line a m of Fig. 2. Fig. 5 is a transverse section in line y 1 of Fig. 3. Fig. 6 is a plan of the pin detached. Fig. 7 is an end view of the plate with the pin removed.

Like parts are designated by corresponding symbols of reference in all the various figures.

The object of this invention is the production of an efficient, serviceable, simple, and comparatively cheap fastening-pin, usually termed a safety-pin.

A in the drawings represents a metallic plate made from any suitable material, such as aluminium, brass, German silver, silver, or gold. It is of substantially rectangular form, and it has its two longitudinal edges downwardly and inwardly curved at 2 3, so as to form in this plate two grooves 4 and 5, wherein is located a pin B. (Shown most clearly in Fig. 6.) This pin is constructed of a wire rod of suitable diameter and length, having one of its ends pin-pointed at 6 and the other end bent at an angle at 7 and then at a double right angle at 8 and terminating in a U-shaped portion 9, the latter portion or member being of such dimensions that its parallel members 10 and 11 fit snugly, yet slidingly, within the grooves 4 and 5 of the plate A. The metal of this pin being rather hard, this U-shaped portion of the pin is resilient and there fore capable of retaining any position (by frictional contact within the grooves 4 and 5 of the plate) into which it may be placed on said plate A. The pin B has near its point 6 a bend 12, Figs. 1 and 4, of an angle of aboutforty-five degrees, (more or less,) and then a straight portion 13, terminating at the angle 7, said straight portion running substantially parallel with the plate A. This pin B is placed into the grooves 4 and 5 with its U-shaped portion 9, and then these grooves 4 and 5 are closed at their ends at 14 and 15 to prevent the pin from being withdrawn from the plate A. In applying this pin B it is pushed forward by catching hold of the plate with the fingers and pushing the portion 7 with the thumb, so as to occupy the position shown in Fig. 3, in which position the U-shaped portion 9 strikes the stop 15, when the point 6 of the pin may be pushed into the material, garment, or other part 16, Fig. 4, until it emerges therefrom. It is then further pushed along until its point 6 emerges therefrom on the upper or entering side of the garment and then the plate pushed forward to protect the point of the pin until the U-shaped portion 9 strikes the stops 14 on the plate 4. In this manner the material, garment, &c., are securely held together by the pin.

Among the advantages obtained by this construction of this safety-pin are simplicity, cheapness of construction, durability, and neatness. The material on which it is used cannot be injured or torn, nor can the pin'be lost.owing to the fact that the bend portions of the pin proper prevent its ready removal, which can only be accomplished by lifting the rear end of the plate (that shown to the right in the figures of the drawings) and by giving it an upward and rearward movement.

It is obvious that the plate may be soldered. brazed, or otherwise fastened to any ornamental jewelrysuch as a stick-pin, hatpin, scarf-pin, brooch, and the likewithout the slightest change or modification.

The stops 14 and 15 heretofore mentioned are formed by depressing the edges of the plate A at the ends of the grooves 4 and 5; but they may also be produced in any other desirable and convenient manner without departing from the scope of this invention.

Having thus fully described this invention, I claim as new and desire to secure to me by Letters Patent of the United States An improved safety-pin, consisting, essentially, of a plate having both of its longitudinal edges downwardly and inwardly bent to form grooves; a pin consistingof a single piece of wire having one of its ends pointed to serve ASA IV.
