DASH-LOCK FOB AUTOMOBILE-CLOCKS.

Specification of Letters Patent.

Application filed March 19, 1913. Serial 110. 755,541.

To all whom it may concern Be it known that I, VVrLsoN E. Poimsn, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Dash- Looks for Automobile-Clocks; and 'I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Figure 1 a View partly in side elevation and partly in broken vertical section showing my improved dash-lock for automobile clocks with the lock in its locked position. Fi 2 a corresponding view with the lock in its unlocked position. Fig. 3 a detached view in front elevation of the dash-plate. Fig. 4 a detached rear view of the clock. Fig. 5 a detached plan view of the double key. Fig. 6 an end view of the locking-end of the winding key.

My invention relates to an improvement in dash-locks for automobile clocks, the object being to produce a simple and convenient lock constructed with particular reference to accurately positioning the clock when first applied to the dash, and to preventing the clock from working loose under the jar of the automobile, or from being worked loose by the turning of a part of the clock or its bezel if it is a keyless clock, and winds by the rotation of its bezel or other rotary winding-member.

With these ends in view, my invention consists in a dash lock for automobile clocks, having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a circular dash-plate 2 adapted to be permanently fastened by screws 3 directly to the dashboard 4 of an automobile. The said plate 2 is provided with an integral positio'ningfinger 5 projecting above its upper edge and adapted the dash and whichis inclined with respect to the case-band 8 so as to give the face of the clock an upward inclination in the usual manner as shown in Figs, 1 and 2. The said base-ring 9 is larger in diameter than the case-band 8, and also larger in diameter than the dash-plate 2, and serves to entirely Patented Oct. 21, 1913.

conceal the positioning-finger 5 thereof and the entrance of the said finger into the positioning notch in the rear edge 7 of the band 8, so that when the clock is applied to the dash, the dash-plate 2 is housed, and the positioning-finger and positioning-notch are entirely concealed from view.

The. case-back 10 which is fixed within the rear end of the band 8 at a right angle thereto, is provided, as shown, with a heavy centrally arranged rearwardly projecting fastening-stud 11 adapted to enter and fit snugly into an upwardly inclined socket 12 on the face of the dash-plate 2. The said socket has upon its lower edge a rib 13 having a threaded hole 13 to receive a bindingscrew 14 which enters a hole 15 formed in i the lower face of the stud 11 at a right angle a triangular head 16 which prevents it from being turned by an ordinary key and limits its operation to a special key having a pod 17 with a corresponding triangular opening 18 as well as a pod 19 having the usual rectangular opening 20 for wlnding the clock in case a key-winding clock is used. The key shown is adouble key and formed with the usual bow 21. Access to the triangular head 16 of the binding-screw 1 1 is had through a hole 22 formed in the caseband 8 in line with the hole 15 when the clock is in place upon the dash, and normally closed by a plug 28 which must be removed and replaced by a screw driver.

In using my improved dash-lock, the clock is set over the plate'2 and rotated with respect thereto until the notch. 6 in the band 8 snaps over the positioning-finger 5 of the dash-plate 2, whereby the clock is accurately positioned and thereafter prevented from being jarred loose by the jarring of the car or worked loose by the winding of the clock in case it is a keyless clock. The special key is now employed to turn the bindingscrew 14 into the hole 15 of the fastening stud 11, whereby the clock is firmly and solidly secured to the dash-plate 2. The plug 23 is now inserted to prevent access to to the axis thereof. The said screw 14: has

the screw 14 and to exclude dust from the case. For the removal of the clock from the dash 4, the plug must be first removed from the band 8 after which the special key must be employed to operate the screw so as to release the stud 11 from the socket of the plate 2 from which the clock may now be drawn away.

I claim 1. In a dash-lock for automobile clocks, the combination with a dash-plate provided with a positioning-finger, of a clock having its case formed in its projecting rear edge 'ith a positioning-notch to receive the said fingcr and provi led with a base-ring larger in diameter than the said dash-plate and band and forming a housing for the said plate and the rear edge of the band when the clock is fastened to the dash, and lock ing means for permanently securing the clock-case to the said plate.

2.1n a dash-lock for automobiles, the

combination with a dash-plate provided with a positioning-fingerand with a fastening-socket provided with a. binding-sc-rew of a clock having its ease formed in its projecting rear edge with a notch for receiving the said positioning-finger, and provided with a fastening-stud entering the said socket and bored for the reception of the said screw and the case of the clock being also provided at its rear end with a baseflange or housing larger in diameter than the dash-plate and case and se: ceal the dash-plate and the case when the clock is applied to in testimony whereof, I have 1 specification in the presence of two scribing witnesses.
