' UTOMOBILE-CLOCK.

new and useful Improvement in Automo-v bile-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 in front elevation of a rear-wind and rear-set automobile clockand housing therefor, constructed in accordance 'with my invention and shown as applied to the cowl-board of an automobile.

Fig. 2 a view thereof in vertical section on the line 22 of Fig. 1, with the clock proper mainly shown in side elevation.

Fig. 3 an enlarged broken detail sew tional view showing the construction of the clock and housing, for locking the former in place in the latter, with ample clearance for the clock-case within the housing.

Fig. 4: a detached plan view of the housing with the clock in its locked position therein.

Fig. 5 a view in elevation of the housing, showing the largecoiled ejectingspring in the bottom thereof. v

Fig. 6 a view in rear elevation of the clock proper.

My invention relates to an improvement in rear-wind and rear-setautomobile clocks and housings therefor, the object being to produce a; clock and housing of'simple, com' pact, durable and convenientconstruction designed with particular reference to lo eating the face of the clock bezel as nearly.

flush as possible with the .surfacebf the cowl-board.

With these ends in view, my invention consistsin a rear-wind; .and rearset automobile clock and housing therefor, having 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 rear-wind and rear-set clock of any approved construction so far as its movement is concerned. As herein shown, this clock has a laterally projecting flattened bezel 3 the outer edge of which Specification of Letters Patent.

is knurled as at 4 for being gripped by the tips of the fingers forrotating the clock as required to lock it within, and unlock it from, a cup-shaped container or housing 5 closed at its rear end and provided at its forward end with a fastening-flange 6 formed with countersunk screw-holes 7 by means of which the housing is secured by screws 8 to the cowl-board 9 which is formed with a circular opening 10 into which the housing is set. The rear face of the outer edge of the bezel 3 bears directly uponthe outer face of the fastening-flange 6 from which the bezel 3 projects only to the extent of its own-thickness. The said bezel 3 is formed upon its inner face with an integral, annular centering-band or supporting flange 11 adapted in internal diameterto fit snuglywithin the open outer end of the cup-shaped housing 5 in which it centers the cylindrical clock-case 12, the

open forward edge of which is fitted snugly Since the external diameter of the clockcase 12 is smaller than the internal diameter of the housing 5, an annular clearance space 13 isformed between them when theclock is in position in the housing. The use of the centering-band 11 makes it un necessary to fit the'clock-case, as a whole, into the housing and makes it easy to introduce the clock into the housing move it therefrom.

For locking the clock in the housing, I employ, as shown, two radially arranged lockingpins 16 mounted at opposite points in the centering-band 11, but also extending inward into the outer e'dge'of'the cylindrical clock-case These pins are adapted in length and in position to engage directly with the rear face'of the fastening-flange 6. For this purpose the inner edge of the said flange is formed at opposite points with radial entrance-notches 17, the innerends of which intersect clearance-slots 18 formed in the extreme forwardedge of the and to re winding and I employ an ejecting-spring 19 lowinding-key 20 and the setting-button 21,

the back of the clock-case 12.

For removing the clock for the purpose of winding and setting it, it is rotated clockwise forthe length of the slots 18-to bring its locking-pinsl6 into registration withthe entrance-notches 17 when the ejection-spring 19 immediately acts to eject the clock sufficiently far from the housing 5 to enable it 'to be very readily grasped and withdrawn entirely therefrom for being wound and set,

after which it is reintroduced into the housing with its pins 16 registered-with the entrance-notches 17. The clock is then pushed inward against the tension of the spring 19 until the rear face of its bezel 3 has been brought to a bearing upon the outer face of the flange 6 after which the clock is rotated counter clockwise through its bezel for the engagement of its locking-pins 16 with the rear face of the flange 6, the pins at this time enteringthe clearance-slots 18. The inner edge of the bezel overhangs the crystal 22 which rests upon the usual mat 23,

which in turn rests upon the clock-dial 24. Inasmuch as the clockis not closely fitted into the housing throughout its length, but centered and supported therein only at its outer end by the lateral projection formed by the band 11', the clock is readily removed from, and introduced into the housing. In this connection it may be noted that there is so little friction between the band 11 and the outer end of the housin'g,that the springhas little friction to overcome in ejecting the clock sufficiently to permit it to be readily grasped by the fingers for being entirely. withdrawn from the housing.

I claim 1. The combination with a housing adapted to be mounted in an automobile, of a'rearwind and rear-set clock having a cylindrical clock-case and an independently formed laterally projecting bezel formed with an inwardly extending annular centering-band adapted in external diameter to fit snugly within the forward end of the said housing and ininternal diameter to fit over the forward end of the clock-case to which it is secured, and means for removably securing provided in its forward end with an inde-' pendently formed laterally projecting bezel which overlaps the said fastening-flange and which is formed with an inwardly projecting annular centering-band fitting within the forward end of the said housing and over the forward end of the clock-case to which the band is secured, and means mounted in the said band for removably securing the clock within the housing from which it is removed in tozfo for winding and setting.

3. The combination with a housing adapted to be mounted in an automobile and formed atits outer end with a fasteningflange, of a rear-wind and rear-set clock having at its rear end rearwardly projecting winding and setting means, and provided at its forward end with a laterally. projecting bezel which overlaps the said fastening flange and which is formed with an inwardly projecting annular centering-band fitting within the forward-end of the housing and over the forward end of the clockcase to which it is secured, an ejecting spring interposed between the rear end of the clock and the bottom of the housing and adapted to clear the said winding and set ting means at the back of the clock, and means for removing the clock withinthe housing from which it is removed in 60250 for windingand setting.

In testimony whereof 'I have signed this specification in the presence of two subscribing witnesses. WILSON E. PORTER.
