HAT-PIN SHIELDS Application filed February 1, 1911.

To all whom it may concern:

Be it known that I, ROBERT N. WVELLKE, a citizen of the United States, residing at Pasadena, in the county of Los Angeles, State of California, have invented certain new and useful Improvements in Hat-Pin Shields; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in pin-shields and guards and my object is to improve the construction and increase the efficiency and utility of devices of this character.

A further object is to provide a form of guard which will be locked into position by means of a stud operating in an eye formed in the point of the pin.

A still further object is to provide novel, simple and eflicient means for mounting the beforementioned stud in the body of the uard.

It will also be understood that a primary object which governs to some extent every other consideration is to reduce the cost of the device to the lowest limit possible, consistent with efficiency, sightliness and durability.

Vith the above and other objects in view the invention consists in a certain construction and arrangement of parts and details as is hereinafter more fully described, specifically pointed out in the appended claim, and illustrated in the accompanying drawings, which show a preferred embodiment of the invention.

Referring to these drawings which are attached to and form a part of this application, Figure 1 is a side elevation of the improved guard shown in position on a hat pin. Fig. 2 is an enlarged longitudinal sectional view of the guard itself. Fig. 3 is an enlarged inside end view of a portion of the guard showing the complete method of striking out the clamp portion. Fig. 4 is a detail perspective of the locking pin.

Referring more specifically to these views, in which similar reference numerals desig nate corresponding parts throughout, 1 indicates in general a conventional hatpin, having the pin portion 2 in the point of which is formed a needle-eye 3, and a hemispherical head 4. The guard or look member for the end comprises a hemispherical Specification of Letters Patent.

Serial No. 606,004.

head portion 5 which as will hereinafter appear is preferably formed of stamped sheet metal, and a, pin sleeve 6 of inside diameter approximately equal to the outside diameter of the pin and secured to the hemispherical head portion 5 by soldering to an out-turned flange as shown at 7, or any other suitable fastening means, the same constituting no part of the present invention. Intermediate the length of the sleeve 6 it is perforated as shown at 8 for entrance of the locking pin as will hereinafter appear.

To render the improved device as inconspicuous as possible and at the same time to facilitate the operation of the same I have so formed the operating head as to outwardly resemble the pin head itself, and the operating or locking means is, in conformity with this object, located on the inner plane face of the hemispherical head.

As shown in Fig. 2 this face is formed of a disk here designated 5 secured to the hemispherical head portion by clamping the latter inwardly as shown at 9.

In Fig. 4 a detail view of the locking pin is shown and from this View it will be seen that this pin comprises essentially a bellcrank lever having a depending stud or pin proper here shown at 10, a transverse journal member extending laterally on either side of the angle of the bell-crank and here shown at 11, and a press button member enlarged and formed inwardly concaved to receive and retain the locking spring as will hereinafter appear. In order to secure the locking pin to the disk 5, two small tongues 13 are struck outwardly from the face of the latter. The bearing or pivot member 11 is introduced beneath these tongues which are then bent inwardly as shown in Fig. 2. It will thus be seen that a simple and effective pivot journal is formed in the least expensive manner possible. In order to normally retain the locking lever in its downwardly tilted or operating position a small coiled spring is inserted beneath the inwardly concaved head as shown at 16, the base of this spring being retained by the small in-struck lugs or tongues 17 about which the base of the spring is coiled.

In the operation of the device the pin is inserted in the sleeve 6, the entering point elevating the locking lever against the pressure of the spring 16 as is obvious. When the eye of the pin registers with the aperture of the sleeve the locking pin will descend, thus securing the body of the guard in its place. To remove the guard it is only necessary to direct pressure on the press button handle or end of the lever on which the lockingpin is formed and this pressure will be almost automatic since the natural method of grasping the guard would be to fix the fingers across the inside flat face.

The improved device may be constructed of any desired material and in any form or size to conform to personal judgment or manufacturing requirements, the only essential features being that the locking pin should be disposed and maintained in position as described.

hat I claim is:

In a locking guard for perforated pointpins, a guard member comprising a head portion and a sleeve secured thereto, the inner face of the head portion being provided with out-struck tongues having their outwardly extending points return bent to form journal loops, said inner face being further provided with additional outstruck portions, a locking pin adapted to enter a perforation in the sleeve and co-act with the pin perforation, a bell-crank lever formed integrally with said locking pin, a transverse pivot pin formed integrally with said bell-crank lever and extending beneath said return bent tongues, an inwardly concaved press button member formed on one end of said bell-crank lever, and a coil spring having its lower coils surrounding said additional out-struck portions, and its outer coils contacting with the concave face of said press button member.

In testimony whereof, I aflix my signature, in presence of two witnesses.
