AUTOMOBILE cLocx.

Application flled'August 22, 1921. Serial No. 494,061.

To all whom it may concern:

Be it known that I, WILSON E. PORTER, a citizen of the United States residing at New Haven, in the county of ew Haven and State of Connecticut, have invented a new and useful Improvement in Automobile Clocks; and I do hereby declare theffollowing, when taken in connection with the accompanying drawings. and the character of reference marked thereon, tobe a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Fig. 1 a view in front elevation of an automobile clock installed in a cowl or instrument board, which is partially broken away.

Fig. 2 a rear view of the same.

Fig. 3 a view in vertical section on the line 3- 3 of Figure 1, showing the clock proper and the tube enclosing its windingand settin -stem in elevation.

ig. 4 a detached erspective view of the mounting-cup or cloc -housing.

My inventlon relates to an improvement in automobile clocks of the stem-winding and stem-setting watch type, the object being to provide simple, convenient and effective means for installing such clocks in the cowls or instrument boards of automobiles, .whereby the clocks are firmly held in place and protected against dust and whereby, also, compensation for variations in the thickness of the cowl boards is provided for.

With these ends in view, my invention consists in a clock having the forward ortion of its case provided with a. concen rie overhanging mounting-flange and the rear end of its case provided with a centrallyarranged rearwardly-projecting threaded stud, a mounting cup adapted to enclose the case and formed with a central perforation for the passage of the said stud, andwith clearance for the tube enclosing the radiallyextending windingand setting-stem of the clock, and a nut applied to the said stud and engaging with the said cup for drawing the said flange and cup to a bearing upon the opposite faces of the cowl board.

My invention further consists in certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out my invention, as herein shown, I employ a clock 5 of the watch type, this clock being of any standard construction and enclosed in a cylindrical case 6 having a radially-offsetting rigid tube 7 enclos-- ing the usual windingand setting-stem which is operated by a crown or thumb piece '8 virtually seated in the end of'the tube. The said case 6 is provided upon its forward edge with a concentric overhan ing mounting-flange or'bezel 9 large enoug in diameter to permit it to have substantial bearing upon the cowl board 10 around the forwardredge of the circular opening 11 formed therein for the passage through it from front to rear of the clock-case 6. The

said case 6 is provided upon its rear face with a centrall arranged rearwardly pro- ]ecting threade stud 12 carrying a knurled binding-nut 13. So much of the clock-case 6 as projects rearwardly through the opening ll-is enclosed and protected by a mounting-cup or clock-housing 15, enough larger in diameter than the opening 11 for the engagement of its forward edge with the rear face of the cowl board adjacent to the rear end of the opening 11. The said cup is provided with a central perforation 16 through which the stud 12 projects rearwardly. After the clock and cup have been applied to the opposite faces of the cowl board, the nut- 13 is applied to the stud 12 and operates to draw the flange 9 and the edge of the cup 15 against the opposite faces of the cowl board 10 until the parts are firmly held in place against displacement.

For the clearance of the tube 7 the flange of the cup 15 is formed with an open slot 17 extending rearward from its edge parallel with its axis. It will be apparent that the length of the stud 12 and the slot 17 provide for the application, without alteration, of the clock to cowl boards varying considerably in thickness.

I claim: 1 The combination with an automobile cowl having a circular opening, of a stem-winding and stem-setting automobile clock installed in the said opening and having a cylindrical case provided upon the center of its closed back with a single, fi-xed threaded stud, carrying upon its flange a fixed, downwardly-extending tube for receiving and protecting the windingand settingstem of the clock, and furnished at its open end with a clamping flange to engage with the exposed face of the said cowl; a combined mounting-cup and dust-guard fitting over so much of the said case as projects from the opening in the said cowl, centrally perforated for the passage through it of the said stud and formed in the lower edge of its flange with a slot for the downward passage through it of the said fixed tube; and a nut applied to the said stud for drawing the flange of the case and the open edge of the cup into engagement With the opposite faces of the cowl, and normally closing the perforation in the said combined mounting- 10 cup and dustguard.

In testimony whereof, I have signed this specification in the presence of two subscribing Witnesses" WILSON PURlEl-t.
