HAT-PIN GUARD.

Specification of Letters Patent.

Patented Mar. 19,1912.

Application led July 10, 1911. Serial No. 637,611.

To all 'whom t may concern:

Be it known that I, AUGUST MUELLER, a citizen of the United States, residing at New York city, county and State of New York, have invented a new and Improved Hat-Pin Guard, of which the following is a specification.

This invention relates to a hat pin guard of' novel construction which may be readily applied and removed, and is not liable tov become accidentally detached.

x In the accompanying drawing, which is made part of this specification Figure 1 is a side elevation of' a hat pin guard embodying my invention; Fig. 2 an enlarged longitudinal section thereof; Fig. 3 a cross section on line 3 3, Fig. 2; Fig. 4 a cross'section on line 4 4, Fig. 2; Fig. 5 across section on line 5 5, Fig. Q, and Fig. 6 a detail side view partly in section of the plunger.

A tubular casing is provided with a lower flange which is interlocked with the upwardly turned flange or bead 11 of a centrally a pertured base plate or pin guide 12. Above plate 12 there is secured within casing V10, a resilient plate 18 provided with a pair ot opposed slots L14. and an intervening bridge which is divided at the centerI to form a pair of diametrieally opposed spring arms 15. T hese4 arms thus form an integral portion of plate 13, the free ends of the arms being notched as at. 16. Above plate 13 there is arranged a third coniform apertured plate or cap 1T that serves to limit the inward play ot' spring arms 15. The rim ofconform plate 17 and that of resilient plate 13 are interposed between the endffiange of casing 10 and pin guide 12, so that the beaded edge of' the latter serves to securely attach plates 17 and 1 3 to the casing. Axially through easing 10, there extends a tubular plunger 18 passing outwardly through the apertured head of the casing and here provided with a readily accessible button or finger piece 19 that closes the plunger. The inner end of the plunger passes freely through the central aperture of cap 17 and is by prongs 20 connected to both of the spring arms 15, near the free ends thereof. l

In use the hat pin 21 is with its pointed end pushed into casing 10, so as to pass through apertured base plate 12 between spring arms 15, and into the hollow of the tubular plunger 18. By the introduction of the pin into the casing, the spring arms will become slightly deflected so as to obtain with their notched ends 16, a firm grip on the pin and thus securely lock the guard thereto. By slightly drawing the plunger out, the spring arms will be swungapart to release their hold on the pin, so that the latter may be readily withdrawn.

It will be seen that the device may be readily manipulated, that it is of neat appearance, and that it effectively incases the protruding end of the pin, so that dangerous contact therewith is averted.

I claim:

A hat pin guard-comprising a tubular casing flanged at one end. a centrally apertured coniform plate, a divided additional plate having a pair of opposed spring-arms, a pin guide interloeked with the casingfiange, and securing the conif'orm plate and the divided plate to the casing, and a tubular plunger adapted to receive the pointed end yof a hat pin. said plunger extending outside the casing at the end oppositel the pin guide and being engaged by the spring-arms, whlle the conit'orm p ate constitutes a bearing for the plunger and also a check for llmltmgthe inward play of the spring-arms.
