SAFETY-CATCH FOR BROOCH ES, ac.

$PECIFIGATION forming part of Letters Patent No. 719,919, dated February 3, 1903.

Application filed June 20, 1901.

To all whom, it may concern.-

Be it known that I, GEORGE W.WASHBURN, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Safety-Catches for Brooches and other Articles, of which the following is a specification.

This invention relates to what are commonly termed safety-catches for the pins of brooches, for safety-pins, and other kindred devices, the object being to provide a catch whereby the pin, engaged therewith may be locked within it, and thus the pins accidental disengagement therefrom beprevented and the loss of the article be precluded.

In carrying out theinvention 1 provide a tube closed at its outer end and open at its inner end and having an openingat one side by means of which the pin may have its point inserted within the tube, wherein it is locked against accidental displacement by means of a surrounding sliding guard of peculiar construction applied to the tube frictionally in such way as to hold it in adjusted position, all as I will proceed now more fully to describe and claim.

In the accompanying drawings, illustrating my invention, in the several figuresof which like parts are similarly designated, Figure 1 is a perspective view of a brooch with the pin free. Fig. 2 is a similar view ofabrooch with the pin locked. Fig. 3 is a side elevation, parts locked. Fig. 4 is an inner end elevation of the catch detached, with the guard partly broken out. Fig. 5 is a cross-section of the tube taken substantially in the plane of line A B of Fig. 6. r Fig. 6 is a longitudi nal section of the detached safety catch. Fig. 7 is an end view of the slide or guard detached. Figs. 4, 5, 6, and 7 are on substantially the same scale and enlarged with reference to Figs. 1, 2, and 3.

The plate orbody 1, which supports thepin 2 and thecatch 3, may be of any approved construction and design. The catch itself comprises ahook 4, having afoot 5 or other medium for connecting it with the plate or body, and also having a bill 6. To this bill Serial No. 65,884. (to model.)

portion of the hook is applied atube 7, the outer end 8 of which preferably is closed, while the inner end 9 next the hook is open, and in one side of this tube is a longitudinal slot or opening 10, which is coterminous with the mouth of the bill of the hook.

It will be understood from the foregoing that thepin 2 is engaged with the catch by slipping its point into the tube through the opening 10 and the bill of the book. In order to lock thepin Within the tubewhen thus applied and to provide for its retention therein against accidental displacement, I employ a slide composed of aring 11, within which is asplit ring 12, secured, as by solder, at 13 to thering 11, and the said split ring is a contractile ring in order to exert sufiicient friction or pressure between the tube and the slide to hold the slide in any given position. As sufficiently indicated already, this slide is capable of movement longitudinally of the tube, so-that it may be moved to the outer end of the tube, as in Fig. 1, in order to uncover the slot in the tube sufficiently to permit the ingress and-egress of the pin and also may be moved inwardly, as in Figs. 2 and 3, to retain the pinwithin the tube. In order to prevent the escape of the slide outwardly from the tube, astop 14 is provided at the outer end of thelateral opening 10 in the tube and at substantially right angles to the tube.

It will be observed that the hook itself takes the strain that is imposed upon the pin in use, and thus the tube which is relieved of the strain may be made quite light.

By the construction described a very simple and efficient safety-catch is provided for use in brooches, safety-pins of various kinds, and other kindred articles.

I do not limit the invention to the exact details of construction; but an essential characteristic of my present device is a sliding guard surrounding the pin-receiving tube and comprising a contractile split ring whereby the guard is securely held in its respective positions.

I use the term guard with reference to the device hereinbefore mechanically described as a slide, its function being that of a guard.

What I claim is 1. A safety-catch for brooches and the like comprising a hook, a tube having an end opening and a lateral opening, a pin which enters said lateral opening when it is hooked, and a sliding guard having as part thereof a contractile split ring surrounding said tube.

2. A safety-catch for brooches and the like comprising a hook, a tube having an end opening and a lateral opening, a pin which enters said lateral opening when it is hooked, and a sliding guard having as part thereof a contractile split ring surrounding said tube and a solid ring within which said split ring is secured.

3. A safety-catch comprising a pin-engaging hook, a tube having an open end adjoining the hook, a closed outer end, a pin-receiving lateral opening and a stop at the outer end of said lateral opening, and a sliding guard having as part thereof a contractile split ring surrounding said tube between said hook and said stop.

4:. A safety-catch, comprising a hook, a tube applied to the bill of the hook and-having an end opening and a lateral opening coterminous with the mouth of the bill of the hook, and a guard consisting essentially of a split ring next the tube and within an outer ring.

5. A safety-catch, for brooches and the like, comprising essentially a hook having a bill, a tube applied at substantially right angles to the said bill and having a lateral opening substantially coterminous with the mouth of the bill, a stop at one end of said lateral opening, and a slide applied to said tube and comprising a contractile split ring embracing the tube and a surrounding solid ring to which the split ring is secured.
