H. s. BREWINGTON. SAFETY PIN.

HENRY S. BREVVINGTON, OF BALTIMORE, MARYLAND.

SPECIFICATION forming part of Letters Patent No. 606,374, dated June 28, 1898. Application filed November 153, 1897. Serial No. 658,485. (No model.)

To all whom it may concern.-

Be it known that I, HENRY S. BRE WINGTON, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented a new and useful Safety-Pin, of which the following is a specification.

My invention relates to safety-pins,and more especially to that class of safety-pins made wholly of wire, one end of which forms the pin and the other the shield to receive the.

point of the pin when in use. i

The object of my invention is to provide a safetypin of this class with an improved shield for the point which shall be simple, cheap, strong and durable and which will permit of the ready entrance of the point of the pin into the shield from either side of approach thereto.

WVith this object in view my invention consists in a safety-pin and point-shield made of a single piece of wire, one end ofwhich is pointed to form the pin proper, the central portion being coiled to form the spring, the main body of the pin, which connects the shield with the spring-coil, being substantially parallel to the pin portion, and the outer end of the body portion being bent upward and given a return-bend substantially in the reverse of the direction of the body portion, thence bent to form a singlecoil upon one side of its return-bend, thence over the outside of the return-bend, and again bent on the opposite side of the return-bend to form another coil, these coils, with their connect.- ing portion and the return-bend of the body, forming the shield to receive the point of the pin when locked in position.

In order to enable others skilled in the art to which my invention most nearly appertains to make and use the same, I will now proceed to describe its construction and operation, reference being had to the accompanying drawings, forming part of this specificatiou, in which Figure 1 is a perspective View of a safetypin constructed in accordance with my invention, with the pin in its open position and shown in its closed position in dotted lines. Fig. 2 is a view of the same in side elevation, the pin being locked in the shield. Fig. 3 is a top plan view of the pin as shown in Fig. 2. Fig. at is a fragmentary detail perspective view ofthe shield and a portion of the body, part of the pin being shown in dotted lines. Fig. 5 is a top plan View of the shield and the point end of the pin proper in position in the shield. Fig. 6 is a transverse vertical sectional view taken on the line 6 6 of Fig. 2, looking in the direction of the arrow. Fig. 7 is a view in elevation of the shield end of the pin.

Like letters of reference mark the same parts wherever .they occur in the various is curved upward and then given a returnbend, as at G, from which point it is bent to form a coil H on one side, which ends at the point I, from whence the wire is bent at J over the top of the return-bend G, and again bent into the form of a coil K, which ends at the point L against the cross-bend J.

The coils H and K begin and end at the same point, which is directly in a vertical line with the point B of the pin A, and their inner portions are slightly apartto permit of the free entrance of the point of the pin between them when passed under them from either side, andithe locationof the bendJ with reference to the coils, as well as the location of the coils themselves, will cause the pin-point when pressed toward the shield to slide off the bend J of the shielduponbne side or the other.

main body until it can be adjusted into the shield from below.

From the foregoing description it will be apparent that I have produced an exceedingly cheap, simple, strong, and durable pin of the class described, and while I have illustrated and described what I consider to be the best means for carrying out my invention I do not wish to be understood as restricting myself to the exact details of construction shown and described, but hold that any slight changes, such as might suggest themselves to the ordinary mechanic, would properly fall within the limit and scope of my invention. Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

The herein-described safety-pin, formed of a single piece of Wire, comprising the pin abutting, at L, against the cross-bend J, all 25 substantially as described.
