ARTHUR THOMAS BALL, OF MOUNT VERNON, NEW YORK.

Specification of Letters Patent. Patented Sept, 26, 1911, Application filed April 5, 1911.

Serial No. 618,989.

Toall whom it may concern:

Be it known that I, ARTHUR T. BALL, a citizen of the United States, residing at Mount Vernon, Westchester county, State of New York, have invented certain new and useful Improvements in Pin-Guards, of which the following is a full, clear, and exact description.

My invention relates to what I will term a pin-guard, the same being a useful appliance to be employed in connection with any sort of pin, guarded for any purpose.

In the drawings I have shown my invention as applied to a hat pin and also to a scarf pin. In the former event, it protects the point of the pin and in the latter event, it prevents danger of loss.

The invention consists primarily in the novel construction of the guard, which, as shown, is of the greatest possible simplicity.

In the drawings, Figure l is a side elevation of a hat pin having a guard applied thereto, constructed to embody my invention. Fig. 2 is a longitudinal section of the pin-guard proper, showing a pin in place. Fig. 3 is a plan view of the parts as shown in Fig. 2, the outer sleeve being shown in section. Fig. 4L is a cross-section of the parts shown in Fig. 2, said section being taken at the middle of the guard. Fig. 5 is a similar section of a modification. Figs. 6, 7 and 8 illustrate details.

The guard proper is constructed to slide upon a pin and frictionally grasp the same. It comprises only three parts, an inner tube l, an outer tube 2, and a spring 3. The inner tube is cut away on one side and longitudinally, as shown in Fig. 7 to provide room for a spring 3. The spring 3 is bowed downwardly so that its intermediate portion will project into the bore of the inner tube. The ends of the cut-away portion of the inner tube afford seats for the two ends of the spring 3. When the spring is in place in the cut-away portion of the inner tube 1, the outer tube is slid over the parts as shown in Fig. 2 so as to cover the spring and spring opening and so as to hold the spring 3 permanently in place.

As shown in Fig. 4, the under side of the spring 3 may be flat, or, as shown in Fig. 5, the under side thereof may be channeled longitudinally to engage a pin throughout a greater area. By preference, one of the tubes, for example, the inner one, is made somewhat longer than the outer tube 2 so that when the parts are assembled, the ends of the longer tube may be offset to prevent the longitudinal separation of said tubes when once assembled. It is preferable to make the inner tube longer because by so doing the ends may be spun outwardly, thereby giving a rounded, or somewhat bellmouthed, pin entrance to the guard.

In Fig. 2 I have shown the guard as it appears in use. In this form the guard is suitable for a scarf-pin. In other instances the guard may have an ornamental covering or attachment, such as 4, of any desired design appropriate as a hat-pin head, the guard proper boing secured to the ornamental covering 4 in any desired manner, as by solder.

Vhat I claim is:

A pin-guard comprising two tubes, one iitting within the other, said inner tube having a longitudinal slot formed in one side thereof, a bowed spring located within said slot, supported at each end by and between said tubes, the intermediate portion of said spring projecting into the bore of the inner tube, and means for holding said tubes against longitudinal separation.
