SAFETY-CATCH FOR BREASTPINS AND THE LIKE.

Specification of Letters Patent.

Patented Nov. 16, 1920.

Application filed March 1, 1920. Serial No. 362,512.

has for an object to effect betterments therein of a character to improve the functions of such devices and to attain new results therein. It is an aim to provide a keeper device which will automatically close over a pin as the pin is pressed into a stationary 'furcated element, especiallyof a character to apply greater force to the starting movement of the keeper element by engagement of the pin whereby means may be provided to hold the keeper yieldably in open position without liability of interfering with the closing operation of the device or making it difficult; and the means by which this increase of force attained also operates to afford greater movement to the keeper than "is possible in prior devices having pin operated keeper's arranged to close over a pin by movement of the pin to closed posltion. Another purpose of the lnvention is to con struct the keeper element and stationary member in such fashion that they will cooperate with the pin member to prevent accidental opening of the keeper device.

Additional objects, advantages and features of invention reside in the device and will be apparent from the following disclosure, including drawings, in which,

Figure 1 is a side elevation of a brooch and pin-keeper constructed in accordance with my invention, approximately actual size.

Fig. 2- is an outer side elevation of the keeper device proper, greatly enlarged,

Fig. 3 is a similar viewshowing the device in closed position,

Fig. 4 is a front elevation of the keeper,

Fig. 5 is a rear elevation thereof,

Fig. 6 is an inner side elevation,

Fig. 7 isja top View thereof, with the parts in open position. 7

There is illustrated a base bar 1 of a brooch upon which any usual or special namental work may be mounted, this bar having ears 11 thereon at one end between which there is pivoted a usual form of spring 12 provided with a heel 13 by which the point of the pin is caused to spring outwardly, or away from the bar 10. A keeper 14 is provided upon the bar adjacent the end opposite the one having the ears 11 thereon, this keeper device comprising a base body adapted to be stamped from sheet metal and bent into a U-shaped shape, to provide spaced ears 15 and 16, with a connecting bight portion 17 at the base, which may be soldered or otherwise secured upon the bar 10; and pivoted between the ears 15 and 16 there is a keeper proper 18.

The ear 15 is sloped toward the rear side 19 of the bar 10, and the car 16 has a rear portion extending an equal distance toward the rear. Between the outer part of the car 15 and the rear part of the car 16, there is fixed a pivot pin 20, carrying the keeper 18. Two aws 21 and 22 respectively are formed on the ear 16, the one being projected upwardly above the pin 20, which is located rearwardly of the medial longitudinal ver tical plane of the device. The forward side of the jaw 21 is inclined forwardly toward its lower part, forming one side of an inclined slot 23 between the jaws. The front jaw 22 therefore has a rearward inclination toward its upper part to form the front side of the slot. The slot terminates at its lower part on a plane adjacent the axis of the pin 20 and is of a suitable width between the jaws to freely receive the pin 12 for oscillation therein.

The keeper 18 comprises primarily a hook portion 24, the base of which receives the pin 20 therethrough, and projected forwardly from the base of the keeper there is an operating jaw and detent member 25 serving three functions as will be subsequently explained. The jaw 25 is broadened so as to form a stop portion 26 adapted to strike the bottom of the bight between the ears 15 and 16 when the keeper is in closed position, as shown in Fig. 3. At this time, the upper side of the aw extends approximately horizontally closely adjacent or on a level with the bottom of the slot 23. The bill 27 of the hook 24 is so formed that when the device is in closed position the inner face of the bill ext-ends vertically a short distance, or in such relation to th opposing face of the stationary jaw 21 that upon opening movement of the keeper device when the pin is engaged therein, the pin will be caught between the jaw 21 and the hook bill, and opening movement oi": the keeper prevented, unless the pin is depressed so that the hook may clear it. The opposed faces of the hook and jaw 21 in the present construction are nearly or quite parallel when the pin becomes coengaged therebetween, although a slight variation "from parallelism is permissible, owing to the outward pressure oi the pin. The point portion oi: the jaw 25 is bent laterally to a slight extent, as clearly shown in Fig. 7, so that it engages between the jaws 21 and 22 when the keeper device is in open position, and being snugly held between the cars 15 and 16, a slight wiping action occurs between the point portion of the operating jaw and the statonary jaw 22, an inclined portion being presented to the jaw 22 so that initial movement of the keeper "from open position is slightly retarded, the device being yieldably detained in open po sition in this way.

The keeper is provided with a finger piece 29, located upon the outer edge of the bight of the hook 24-, where it may be conveniently reached for opening of the device when necessary. The keeper is also provided with a heel lug 30 upon its rear edge, so arranged as to strike against the rear part of the bar 19 when the device is moved to full open position. 1

It will be seen that when the device is in open position the pin member 12 becomes wedged between the outer parts of the operating jaw and the stationary jaw 21, so that a slight pressure upon the pin is sufiicient to overcome the resistance of the point 28 to opening movement of the keeper. Continued pressure upon the pin 12 causes it to pass downwardly through the slot 23 moving the jaw 25 until the stop portion 26 engages against the base of the device as shown in Fig. 3. The hook will then have been moved across the slot 23 so that its inner, surface is alined with the upper end portion of the jaw 22, which is suitably formed for the purpose. Release of the pin 12 will then permit it to spring outwardly into the hook of the keeper. Opening of the device is accomplished by pressing upon the pin 12 until it moves into the lower part of the slot 23, and then pressing upon the fingerpiece 29 to move the keeper into open position. The point 28 of the keeper bears upon the arm 22 throughout the movement of the keeper, so that loose movement of the parts is prevented at all times.

What is claimed is: v

1. A pin keeper for brooches and the like comprising a body element having stationary jaws thereon shaped to form a pin receiving slot therebetween, a keeper element pivoted laterally of the lower part of the slot, and having a hook portion movable into closed position over the outer part of the slot to aline therewith, said keeper including an operating jaw member having a face positioned to li across the lower part of the slot when the device is in closed po sition, and to set at an angle and in close relation at its outer partto one of said first named jaws to-receive a pin member in wedging. engagement between their outer parts for sliding movement into the slot and on said operating jaw, and a pin member mounted and constructed to be held resistingly in said device, and of a size to wedge as described.
