BROOCH Application led August 6, 1930. Serial No. 473,306.

This invention relates to brooches, and in particular to improvements in convertible rooches.

The common type of brooch comprises a e body member, usually jeweled or otherwise decorated, provided on its reverse or under side with a pin by means of which the brooch is secured to the clothing of the wearer. Brooches of this type have been made and l worn from time immemorial.

There is another type of brooch which has of late attained considerable vogue and which is generally referred to as a clip brooch. This brooch comprises a decorated body member, butinstead o the pin of the common brooch, is provided on its reverse side with a spring-pressed clamping member or jaw which cooperates with the body member to grip a section of the wearers clothing. Such a brooch may be snapped over the hem of a gown at the throat or shoulder for purely decorative purposes, used for gathering the bertha of a dress, to secure a scarf, or employed in divers ways which need not here be enumerated.

Attempts have been made to make a convertible brooch, one in which two clip brooches may be assembled and used as a single pin brooch and then disassembled and 3@ used separately. (By this means ownership of three brooches can be acquired for the price oiE two-a consideration o some importance when expensive jewelry is involved.) Thus two clip brooches are placed together, end to end and held so by means of a plate, or other connecting member extending across their under sides and screwed in place. This plate being provided with a pin converts the two clip brooches, their clamping i0 members temporarily inoperative, into a common ordinary pin brooch-that is to say, after a fashion.

Doubtless after the connecting plate is screwed onto the clip brooches a single brooch results, but the modus operandi is not satisfactory. The little screws get lost. The operation is laborious and does not commend itsel to those who wear brooches. Then too such a combination brooch is likely to be 5@ clumsy.

In accordance with the present invention I have provided a pair of clip brooches and means for quickly and easily joining them to form a single pin brooch. The operation, both of assembling and disassembling can be performed in a twinkling by any one. No screws are required and' the combination brooch is neat, strong and handsome. At the same time I have eliminated the separate s rings commonly' used in connection with 60 e clamping members of the clip brooch unit-s and have greatly improved the appearance and efficiency thereof.

The improved clip brooch of my invention comprises a body on which is pivotally e5 mounted a resilient clamp, preferably U- shaped. The ends of this clamp are provided with opposed journal pins supported within spaced bearings on the body. The bearings and clamp ends are provided with coacting cam faces so designed that as the clamp is swung outward its arms are spread and the clamp thus placed under tension which urges its return into contact with the body `until it reaches a neutral postion at approximately 45 to the body. Beyond this the clamp is biased toward a vertical position. Thev cam faces are so designed that in both limiting positions, the horizontal and vertical, the parts snap into fixed position and the tension on the clamp is relieved. The cooperating faces of the clamp and body are, of course, provided with means for gripping the clothlng of the wearer. This clip brooch has no separate spring and relies for its eiectiveness on the natural resiliency of the clamping member.

In order to assemble two of these clip brooches to form a pin brooch I provide a bar which extends across the backs of the clip broochcs when they are laid end to end and passes between the spaced bearings 0n each brooch. This bar is provided with holes which are alined with the journal pins. When the clamps are swung downward into contact with the body these journal pins, due to the design of the cam faces and the resilience of the clamps, are moved axially and pass into the holes on the bar; thus the two clip brooches are held firmly altogether and form a single brooch which may be used in the ordinary manner. The ber is, of course, pro vided with the usual safety pin.

In the accompanying drawing I have illusu trated a preferred embodiment of my invention. In the drawing, F igure il is a perspective view of the assembled. brooch; Figure 2 is a plan view'of the brooch when assembled; Figure 3 is an enlarged transverse section taken along line 3 3 of Figure 2, illustrating the manner in which the journal pins are mounted and the manner in which they enter the holes in the common connecting bar; Figure 4 is a, detail showing the structure of the coacting cam faces, the journal pins being illustrated in retracted position; Figure 5 is a. detail of the connecting bar and Figure 6 is a perspective vicwfshowing the relation of the parts during assembly or disassembly and before the connecting bar has been secured in place.

The clip brooch illustrated comprises a body 10 having a jeweled or otherwise decorated face 11. On the back, or reverse side, a. resilient U-shaped clamp 1i? is pivotally mounted in the following manner: The ends of the clamp are inturned and terminate in opposed coaxial journal pins 13 normally urged toward each other by the resiliency of the metal of which the clamp is made. These pins are journaled within bearings A- mounted upon the body and spaced apart. The outer face of each bearing is provided with a. cam face having four equi-snaced notches 15 and the corresponding inner face of each inturned end of the clamp is provided with a coacting cam face having four equi-spaced projections 16 designed to interlit with the notches 15 when the clamp is in either of its limiting positions, horizontal verticals f we assume the parte in closed position as illustrated in Figures l, 2 and with the clamp lying along the back of the body, the projections 16 lie within notches 15 and the journal pins 13 extend toward euch other and almost abut. lVhen the brooch opened to permit the insertion of a piece of clothing the clamp is swung outward. This swinging movement causes the cam projections 16 to ride up along the sloping side walls of the notches 15, thus spreading the arms of the clamp, retracting the pins 13 and placing the clamp under tension. lVhen the projections 16 have reached the dat outer face of the bearing the parts occupyT the position ill strated in Figure Il. Upon swinging the clamping member further upward projections 16 again enter the notches but in e position removed 90 from the originel position. Although the clamp is under tension.l

when the parts are in neutral posit on, as illustrated in Figure 4, it is moved i, vo horizontal and vertical positions by this tension only when the projections 16 enter the notches 15. l

The lower face of the clamp is provided with two downwardly extending points 17, and the body with 'two upwardly extending series of teeth 18 both of which are designed to bite into the clothing and hold the brooch firmly in position.

The two clip brooches are assembled to form a single pin brooch in the following manner: 'Die clamps 12 are moved into neutral position, as illustrated in Figures 4 and 6, in which position the pins 13 are retracted. A connectin bar 19 is thereupon laid across the backs cfg the two clip brooches, as illustrated in Figure 6. Each end of this bar is provided with a. hook 2O which is inserted beneath a loop 21 on the body of each of the brooches and the two snap brooches swung into alinement, the bar passing between the two spaced bearings 14. Wlhcn the parts are in this position the clamps 12 are swung downward, this movement causing the journal pins 13 to move axially toward each other and enter holes E22 in the bar. The parts are now firmly joined and the two clip brooches converted into a single pin brooch. The bar is, of course, provided with the usual pin 23 provided with a safety catch 24. To disassemble the parts, the operations just described are reversed, the clamps swung into neutral to retract the pins 13, and the bar 1S) removed.

The individual clip brooches of my invention are simple in construction and use, have no separate springs to break, and are strong, durable and attractive. The two can be quickly and simply assembled to form a pin brooch and as quickly and simply disassembled. No mechanical skill is required and no tools. Gnly one eXtra part is necessary-a light connecting bnr. Thus 'the inu convenience arising from loss of screws and other arts is minimized and a neat, light and Graceful assembly `achieved.
