Be it known that I, GEORGE WILLmM DOVER, a citizen of the United States, residing at Granston, in the .county of Providence and State of Rhode Island, have-invented a new and useful Improvement in Safety- Catches for Brooches and the like, of which the .following is a specification.

In the usual construction ofsafety catches for brooches and similar articles of jewelry, the parts of the catch are first assembled into a complete operative device, before solder ing, and the keeper or relatively stationary member-is then soldered to the brooch or similar article of jewelry, The movable or locking member of the catch, which is necessarily small and delicate, must be strong and rigid to hold its shape and to operate props erly, when in use. The heat generated. in soldering on the completed catch anneals, weakens or distorts the locking member of the catch, thereby causing the catch to work improperly and in some cases ruining the utility of the catch.

The object of my invention is to produce such a safety catch in two separate parts, whereby the keeper or relatively stationary member is first soldered to the article and the locking member then operatively secured in place by clamping the sides of the keeper together over the lockin member.

A further object of. my mvention is to im prove the construction of such a safety catch,

thereby improvin the operation, forming a more positive 100 prolonging the life and reducing the cost of the catch.

a My invention consists in the peculiar and novel construction of a safety catch for brooches and the like, said safety catch havin details of construction, as willbe more fu ly set forth hereinafter and claimed.

Figure 1 is an end view of a brooch provided with my improved safety catch with the catch in the open position in full lines and in the closed position in broken lines.

Fig. 2 is a sectional view 'of the safety catch end of the brooch taken on line 2.2 of Fig. 1. with the catch in the closed or locked position.

Fig. 3 is an inside plan view of the blank from which the keeper or relatively stationary part of the catch is formed.

Fig. 4. is a sectional view through the blank taken on line 4.4 of Fig. 3.

SAFETY-CATCH non noocrms AND THE LIKE.

Speeification of Letters Patent. P t t a 21, 19 1 Application filed September 20, 1918. Serial No. 254,922.

b Fig. 5 is a side view of the locking mem- Fig. 6 is an edge view of the locking member,and .f

Fig. 7 is a sectional view showing the lock ing member inserted in the bent up keeper in the position for movably securing the locking member in the keeper by clamping the sides of the keeper together.

Allof the figures in the drawing are enlarged to more clearly show my invention.

In the drawing 8 indicates the body of a brooch or similar article of jewelry, 9 a pin tongue and 10 my improved safety catch which consists when completed, of a relatively stationaryykeeper 11 and a movable spring locking member 12. The keeper 11 is first struck out in-blank form and shaped to have a base portion 13 and circular side ortions 14.14 in each of which is a coinci ing central pin-tongue opening 15, a radial entrance and egress opening 16, an annular groove 17 semi-circular in cross section and flattened portions $18.18 which when the sides are closed forms a curved slit 19 between the sides, a s shown in Fig. 2. The blank is then bent up V shaped, as shown in Fig. 7. The locking member 12 is made of round spring wire circular in form to loosely fit in the bore formed by the annular grooves 17.17, and has the pin notches 20.20 and the flattened operating angular end members 21.21 which extend outward from the looking member through the slit 19 as shown in Figs. 5 and 6 and forms an intermediate wedge shaped opening 22, the narrow inner end 23 of which is slightly less than the diameter of the pin-tongue used.

The bent keeper and locking members are supplied separate to the trade as jewelers findings. The base portion 13 of the keeper is then soldered to the back of the brooch or similar article, the locking member 12 inserted between the sides of the keeper as shown in Fig. 7, and the sides 1 1.14 forced together, as shown in Fig. 2, thereby movably securing the locking member in the keeper without annealing and weakening the locking member by the heat generated in soldering the catch on the brooch.

When in use the operating members 21.21 form the wedge shaped opening 22 in connection with the entrance opening 16 in the keeper. The end of the pin-tongue 9 passing through the narrow end 23 of the opening,

springs the members 21.21 apart, the I loose fit of the locking member in the'fkeeper allowing for this. The locking member is then 1 turned by the operating members 21 into the position as shown in brokenlinesfin Fig.1,

spring of the pin-tongue forcingth'e end 10f:

the pin-tongue into the adjacent notch 20 in the locking member, as shown'in' Fig. 2.; iAlthe keeper, said operating'nie'mbersf"forming a spring .wedge shaped opening for a pin on 2. A safety catch for brooches and the like comprising a keeper 11 havingwb'asePortion 13,two sides Flat-:14 in each of. which is a coinciding central opening 15, an entrance opening 16, an annular groove 17 andnflatthough the entrance opening in the keeper -tened *portionsl8, the grooves 111 7 forming is'shown at the'top, it"may-be on the side if required, in which case the locking member would have a locking movement in'one direction. e

Having thus described my "inventi'on I claim as new.
