My present invention has to do with wrist watches of a novel type, in which there are two open ended arms secured to thewatch case or body, and intended to surround the wrist of the wearer but preferably not in Contact with each other on the inside -of the wrist. One or both of these arms is hin ed to the watch-case and the hinge is provi ed with locking means so that when in position on the wrist, the arm is held positively against movement about the axis of the hinge. The arms are also preferably made of some material which can be shaped to fit the wrist of the wearer, the most suitable being celluloid or some other' material'which will soften under heat so that itl may be shaped to fit the wrist of the wearer. A wrist watch of the type just described is not my invention and my present invention is gb an improvement thereon. The object of the resent invention is to provide a more -satis-l actory hinge lock in combination with the other'essential parts of a .watch case of the foregoing character. f `The invention will be more fully understood from the followingl description 'when` taken in connection with the accompanyin drawings and the novel features thereof wi be pointed out 4and clearly defined in the a0 claims at the close of this specification.

Referrin now to the drawingsgat 11 is shown the ody of the watch-case and at 12 the rear cover. At 13 is shown referably a fixed armextension, this being ormed inp tegral with the case 11 or integrally secured 55 thereto. -This arm member is' preferabl narrowed, as shown at a, and is channe sha ed in cross section,y see Fig. 6, to receive the inner end of the arm 14, preferablygmade of celluloid. The inner end of the celluloid arm is widened, as shown at b, td fjit the contour of the interior of this ortion of the member 13, 'and is secured 1n place by a v.15' and screws 16-1I6 t will therefore be seen that'by loosening the two screws 16-,16 the clip 15 may be taken oi and the arm 14 taken out of the arm ,member.13, when it isdesired for any reason` to replace the celluloid arm member '14 by 7o another. In practice it is found desirable to supply celluloid arms of different colors or shapes, and the construction described forms a convenlent means of accomplishing this.

The movable arm 17 is secured to the mova- 75 member 18 in the same way.

At 17 is shown the movable arm extension which is connected with they watch case body lnarrowed portion A18a adapted to receive and rtionc of 'the arm 17. The member 18 1s provided with an outwardly dared or enlarged portion 18b at its inner end carryin hlnge eye members 18o and a latch mem r or lockin device preferably in the form of hooks s own, as a wholeat 19. The member 19 is preferabl l in the form of a split sleeve provided wit spaced slots 20 inits `outer wall, and houses a pair of pins 21, the outer ends of which project through the top and bottom fianges of the portion 186 and are urged outwardl to locking position by means of a spring 21a interposed between their opposed inner ends (Fig. 5). The ins 21y carry laterallydi ne. latch mem o r hook portions 22 w: ich projectthrough the In the form shown the watch-case body 11 yis provided at the end adjacent the movable arm member 17 with a plate 23 secured to the case in any suitable manner. .This plate has an integral substantially right angularly disposed flange or latch plate member 23a provided with slots or openings 23h and with a hinge e e member 24, the latter being alined with the eye members 18o and secured in such alinement by means of a pxintle (not shown) to maintain the movable inge member and the Watch case together. The slots or holes 23?) are positioned to register with the latch members 22 when the movable arm 17 is swun to a closed position as shown in full lineaig. 1. A

The heads or hook ends of the latch members 22 are enlarged to provide lateral extensions or lips 22a having convex outer faces or cam surfaces, Fi 5, adapted to engage the inner face of t e flange or latch member 23a at the slots or openings 236, ride over the plate at points adjacent the other ends of the slots, and engage the inner face of the member 23a at the edges of` the slots 23b, when the parts are brought into register, thereby locking the movable arm extension and Watch case against relative movement and preventing said arm member and hinge from swinging about the hinge pintle, which would release the watch from the wrist of the wearer. the latch members 22 from engagement with the flange 23 so as to swing the arm 17 to an open position so that-the watch may be removed from the Wrist, pressure must be appliedwto -the ends of both'of the pins 21y to cause the inward movement of these pins -thereby releasingy the lips 22a from engage` ment with the e ges of the flange 23a. The depression of onevof the pins 21 is insuiiicient to release the parts. It will be seen therefore that the parts arel maintained in fixed relation against accidental release, the construction described eliminating the possibility of the movable arm swinging about its hinge pint-le and permitting the Watch to fall oi the wrist of the wearer.

Then the parts are closed as shown in Fig. 3, it will be seen that the member 18 and thelatch plate 23 serve to completely conceal the member 19, the onl parts of the locking or latch mechanism s owing being the hook ends or projections 22 and the outer ends of the pins 21.

In Figs. 7 to l0 inclusive I have shown a modified form of hinge member and lock.

-In these iigures, the-fixed arm extension 130 carrying the arm 140 is substantially like the corresponding member 13 of the preceding figures, the arm extension being formedl integral with the case 110 or integrally secured thereto. The enlarged inner end 'b of the arm 140 is preferably secured in position in the hinge member 130 To releasev V180 for actuatin about its hinge pintle, it is necessa by means of a plate 150 adapted to be held 1n position upon the inner face of the hinge member 130 through the medium of screws 160 threaded into fixed sleeves 165 carried by the hinge member.

At- 180, I have shown a movable hingemember or housing generallyv like that of form of a pin 200 having a reduced shank portion 201 having at its inner end a lateral projecting portion or nose 202e provided with a convex outer face. A coil spring 203 within the sleeve'190 surrounds the shank 201. One end of this spring engages the end wall of the sleeve, the opposite end engaging the shoulder of the pin 200 so as to normally project the end of the pin 200 outwardly through one of the flanges of the hinge member 180. y It will be noted that by providing a pair of parallel members 190 each adjacent one ofthe ianges of the member 180, a pin 200 will project through an opening in each of the flanges so as to provide means on opposite sides of the member the latch members 202. v

The end of te watch case body 110 to which the hinge member 180l is connected is provided with a fixed hinge eye 240 adapted to be alined with the hinge eyes 1800 and receive a pintle for maintaining the parts together. The case is also pro- Avided at this end with a preferably centrally disposed projecting latch plate or extension 230, the upper and lower edges 23041 of which i are caused to engage the convex outer faces of the latch members or hooks 202 when the arm 170 is swung inwardly toward the plate 230, causing the noses 202e to ride over the plate edges until the parts are locked in which.' position they are shown in Figs. 7 and 9, with the ends or noses 202aengaging the outer face of the plate or extension 230 to give a neater appearance to that part of the Watch and also to prevent an uncomfortableness to the'wearer. Thev thickness -of the hinge member and plate however is less than t at of the'watch case and cover. To release the arm and permit itto swing to apply pressureto the ends of both ov the pins 200. The depression of one pin only is insufficient to release the arm.y By providing such a construction the accidental release of the parts is prevented. In both forms 'of the invention the hooks 22 4and .v 202 are adapted to engage the inner face of the plates 23a and 230, respectively, when the parts are locked together.
