DETACHABLE WATCH FOB MOTOR-DRIVEN VEHICLES.

Specification of Letters Patent.

Patented Mar. 20, 1916.

Application filed March 25, 1916. Serial No. 86,666.

To all whom it may concern Be it known that 1, CHARLES SoHInBnL, a citizen of the United States, residing at VJatertown, county of Jefferson, and State of lVisconsin, have invented new and useful Improvements in Detachable Watches for Motor-Driven Vehicles, of which the following is a specification.

My invention relates to improvements in detachable watches for motor driven vehicles.

The object of my invention is to provide means for securely clamping the watch to the steering wheel of a motor driven vehicle in such a manner that it can be readily detached and removed with the clamping mechanism, the watch case being permanently 1 connected with one of the clamping members.

In the drawings- 7 Figure '1 is a fragmentary view of the steering wheel of a motor driven vehicle showing a watch embodying my invention clamped toone of the spokes thereof.

Fig. 2 is a rear view of the watch, detached from the spoke of the steering wheel and showing the clamping mechanism partially in releasing position.

Fig 3 is a horizontal sectional viewof a portion of the watch casing and clamplng mechanism, showing the clamping members in clamping position, said section being taken on a plane exposing the clamping bolts or screws. a

Like parts are identified by the same reference characters throughout the several views.

The watch 1 may be of any ordinary construction except that the back wall 2 is rigidly connected at 3 with a clamping plate 4. The central portion 3 of the clamping plate 1 is formed to fit the surface of the watch casing at the center of the back 2 thereof, and is rigidly and permanently secured to the back 2, by brazing, welding or in any other suitable manner. Between this middle portion 3 and the end portions 5, the clamping plate t is bent outwardly or ofiset from the back 2 of the watch casing, to provide 1 ample clearance for the heads 6 of the Acooperating clamping member 9 is pivotally connected at oneend of one of the clamping bolts 7, and the other end portion provided with a key slot notch 11, extendlng inwardly from one side, and terminating in a rounded recess 12, adapted to receive the other clamping bolt 7. Beyond the slot 11, this clamping member is extended to form a lever arm or handle 15, which may be of any suitable contour adapted to facilitate the manipulation of this clamping member. The slot 11 is of such width as to permit an adjustment of the clamping member 9 to a position with the bolt 7 engaged in recess 12. The slot is narrowed at 13 so that force will be necessary in order to move this clamping member to either clamping or releasing position, the bolt binding upon the walls of the slot when passing the converging or inwardly extending marginal portion 13. Each of the clamping bolts 7, 7 is provided with a nut 18, and a lock washer 19 is interposed between each of the nuts 18 and the clamping members. These washers are formed of resilient material and are bent into such form that they will engage resiliently against the clamping member 9 and against the inner faces of the nuts 18. The outer ends of the bolts 7 7, are preferably provided with heads 20 to prevent the nuts from becoming accidentally disengaged and lost. These heads 20, however, are preferably removable, being provided with threaded shanks 21 engaging in the threaded sockets in the bolts 7, (or 7). The middle portion of the clamping plate 9, is provided with a transverse band 25, preferably nonmetallic, and which is adapted to bear upon the spoke 26 of the steering Wheel to which the Watch is to be clamped. The band is loose on the clamping member 9, and is adapted to revolve thereon, when the clamping member 9 is being swung toward or away from clamping position. Both of the clamping members a and 9, being preferably formed of resilient material, and the band 25 being adapted to revolve on the member 9, it is obvious that there will be no danger of marring the surface of the spoke or other support to which the watch is clamped.

To apply the watch to the steering wheel, the clamping member 9 is adjusted to releasing position, and the watch is then placed against the front side of the spoke 26, in

the position in which it is illustrated in Fig. 1, after which, the clamping member 9 is swung upon its pivotal connection with the bolt 7, into clamping position, sufficient pressure being applied to the handle extension 15, to force this clamping member between the lock washer 19, and the opposing surface of the lining member 8, through the end of which the bolt 7 preferably passes. When the clamping member has been moved to the position in which the bolt? is received in the enlarged recess 12, the spoke 26 will be securely clamped between the band 25 and the opposing central. portion of the lining member 8. The contour of the central portion of the clamping members 4 and 9, will, of course, conform substantially to the contour of the spoke 26 at the point where the clamping members engage it. After the clamping member 9 is in clamping position, the nuts 18 may be turned up on the bolts 7 7 for additional security, if desired, but ordinarily this will not be neces sary, particularly if the clamping member 9 is swung downwardly into locking position, as will be the case if the slot 11 is formed to extend inwardly from the lower edge margin, as shown in the drawings. It will, of course, be understood that the clamping members are shown in inverted position in Fig. 2. Clamping member 9 is formed of resilient material. Therefore it may be swung into and out of clamping position with reference to the spoke 26. When it is desired to remove the watch from the steering wheel, it is therefore merely necessary to grasp the handle 15 and lift the clamping lever to releasing position, the watch being, in the mean time, supported by the other hand. It is therefore obvious that the watch may be instantly removed and almost as quickly reattached to the spoke of the wheel, or to any other support to which the clamping members may be adapted to engage.

The clamping member l may be secured to the watch casing by any suitable means, whether by brazing or riveting. It will, of

course, be understood that a specially constructed watch casing will be employed, or, at least, that the back portion 2 thereof will be specially constructed and rigidly attached to the clamping member. I consider this feature of my invention very important to the success of the device, since there is no possibility that the watch may become disengaged accidentally.

I claim 1. The combination with the back of a watch casing, of a clamping member permanently secured thereto, a set of clamping bolts connected with the end portions of said clamping member, an auxiliary clamping member pivotally connected with one of the bolts and adapted to swing into and out of engagement with the other bolt, said auxiliary clamping member being provided with a key slot or recess extending inwardly from one of the side margins in a position to receive said other bolt.

2.
