CLASP.

Application led December 1,6, 1922, Serial No. 607,381. Renewed November 3, 1925.

This invention relates to clasps adapted to be used in connection with watch fobs or as a fastening means for the end of key chains.

An object of the invention is the p rovision of a simple and eiiicient clasp which will grip a part of the clothing and be locked in such a reliable manner that the clasp will be safe against accidental or unf forced inwardly by ,theY spring tongue 9,

The tongue 9 has sutlicient resilience and authorized removal.

Other objects and advantages of the in! vent-ion will become apparent during the course of the following description.

The invention is illustrated by way of example in the accompanying drawings, In which,

Figure 1 is a view in perspective of the clasp attached to a trouser band and used 1n connection with a watch fob.

Figure 2 is an end view of the same.

Figure 3 is a vertical sectional View of the clasp shown in Figure 1.

Figure Il is a viewvin perspective of a modified form of the claspadapted tov be used in connection with a key chain.

Figure 5 is a vertical sect-ion of the same.

Figure .6 lis a view in perspective ofthe clasp Shown in Figures 1 to 3, in open position'.

liteferring to the drawings, 1 designates a front plat-B which may be engraved in any suitable manner in order to display the owners monogram or some design of a fraternal or secret Society to which the owner may belong. Vhere desired, instead of the engraving, the design or monogram may be cut, in the face of the plate. materials employed may be of any typeof metal lsuitable for the purpose. The front pla-te is provided with a slot 2 at its lower end through which is threaded a fob 3. An ear- 4, projecting from a lower .corner of the front plate 1 is perforated to receive a chain 5 which carries a watch located in a pocket 6 of the trousers.

The front plate ,is bent rearwardly as shown at 7 and provided with a returned bent porti-on 3.` Projecting downwardly, and offset from the returned bent portion 8, is an integrally formed spring tongue l9 spaced from the front plate 1. The tongue 9 has considerably less width than the returned bent portion 8. The returned bent portion is .provided upon opposite sides .of

' the tongue 9 with bearings 10. 1 A pin V11 is The integrally formed on each of a pair of legs 13 and 14: of a clamping member 15,

The tongue 9 projectsbetween the legs rigidity to maintain the jaw 19, formed on the lower end of the cla'rping member, projectedV into the slot 2,

The clamping member is provided with an inwardly projecting resilient tongue 20 engaging the slot E20a formed by punching out a portion of the metal vof the locking plate 16 to provide the finger piece 26, The engagement ofthe end of the tong-ue within the slot 2Oa prevents movement of the locking plate 16 on its pivot 17 when the jaw 19 of the clamping member forces the trouserV band into the's'lot 2 of the front plate 1.

It will be noted that the vclasp is adapted to'engage either the trouser 'bandi 21 or a beltwhen locked in positionfto prevent loss of a watch. vThe clasp vshown in Figures 1 to 3 inclusiveis locked-upon a trouserk band andif it be-desired to remove the clasp it is only necessary to exert pressure' on the finger piece 26 whereby the resilient' tongue will be forced inwardly and awayY from the locking member 1.6 to permit the locking member to be oscillated and released gated slot 2 in the plate 1.

end 18 of said locking member is forced be- ,Y

neath the spring tongue 9 as the locking ffii) slot.

Figures 4 and 5 disclose a modication of' the clasp. llhis term ot clasp.' is provided with a front plate 1 adapted to be Vengraved or decorated in a manner similar to the i'ront plate oi: the clasp shown in Figure 1. A resilient tongue 9a and a clamping member 15a are provided, with the clamping member pivotally mounted on the returned bent portion 8 ofthe plate 1. v The toothed jaw 19 ci the clamp projects within the slot 2 of the front plate and is adapted to pinch or torce the part of the clothing so engaged, into said i tongue 2O is provided at Ythe rear of the clamping member` 15EL to engage the notch 2O@l oi the locking plate 161 andy adjacent the 'finger piece 26 which projects'beyond the plane ot the tongue 9a. The end of the tongue or spring member 9a is bevelled as shown at 22.V and adapted to engage the coniplementary bevelledportion 23 et the plate 16 whichvis pivotally connected at 17 to the clamping member 15a. The spring tongue 9a engaged with the locking platey 16 through the `bevelled portion oi the respective members, tends to force the locking plate` M" 16a inwardly while the tongue 2O presses outwardly against the locking plate whereby the locking plate is rigidly heldin place to preventaccidental movement of the clamping member 15a on its pivot pin 11a. The legs 18 and 14 of the clamping member 15EL are provided with journals 27 which are mounted on the pins 11. rlhe pin 1la is rigidly securedto the back of the resilient tongue 9a.

At the extreme end and centrally of theV lower edge of the plate 1 is formed an ear 24 provided with a perforation 2544 which 1s adapted to receive one end ot a chain which is provided with a key ring at its other end.

rl'fhe operation of the modified form of clasp shown in Figures 4 and 5 1s as follows: Pressure upon the linger piece 26 moves the `resilient tongue 2O inwardly. while the bevelled .edge or the locking plate 16a is moved suiliciently away trom the bevelled end oit the tongue 9Ei to permit the locking plate to be swung onY its pivot 17 and moved out ot engagement with the end of the tongue 9%. rlhe clamping member 15d is lnow free to be moved on its pivot and to be swungout- .wardly away irom the plate 1 to release the clasp from the trouser band or from a belt.

It must be borne in mind that the clasp is adapted to be suitably attached to either the band of a pair of trousers or a belt and .of the clasp projects into `the slot 2 and the belt is inserted and slidable inthe space be* tween the pivoted clamping member 15 and the front plate 1 as shown more particularly in dotted lines in Figure 4. l
