STEM WINDING AND SETTING AUTOMOBILE CLOCK.

v Application filed February 13, 1923.

To all fio/tom t may concern.'

Be it known that I, WILSON E. PORTER, 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 Stem vWinding and Setting 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 eX- act description of the saine, and which said drawings constitute part of this application, and represent, in-

Fig. 1 a view in front elevation of a stem winding and setting automobile clock constructed in accorda-nce with my invention.

Fig. 2 an enlarged broken view thereof, with the bezel, dial and hands removed.

Fig. 3 a view thereof, partly in side elevation but mainly in vertical central section.

Fig. 4 a reverse plan view of the movenient thereorn as removed from its case.

F 5 astill further enlarged detail seeticnal view of the upper end of the winding and setting stem, with the wheels carried by it.

lily invention relates to an improvement in stein winding and setting automobile clocks, the object being to provide a simple, compact and reliable time-piece of the character described, constructed with particular reference to ruggedness and durability of construction and ease of operation, and adaptability to cowls of widely varying thickness.

lith these ends in view, my invention consists in a stem winding and setting automobile clock having certain details of construction and combinations of parts as will be hereinafter described and particularly pointed out in the claims.

As herein shown, my invention is applied to an eight-day clock-movement having a main winding-wheel 10 located against the back of the rear movement-plate 11 and meshed into by a relatively small winding pinion 12 mounted upon the rear end of a winding-arbor 13 bearing in and projecting rearwardly through the said plate 11 Serial N0. 618,782.

and having bearing at its forward end in the front movement-plate 14. At its forward end, the said arbor 13 carries a drivenwheel 15 located directly back of the plate 14 and constantly in mesh with a windingwheel 16 loosely mounted upon the projecting upper end of a winding and setting stem 17 located within a bearing-tube 1S secured by its upper end to the cup-like clock-case 19 well back from the front thereof. The said stem 17, which has limited longitudinal as well as rotary movement in the tube 18, is furnished at its lower end with a winding and setting button 20. Upon its upper face, the said winding-wheel 16 is provided with face ratchetteeth 21 normally meshed into by corresponding face ratchet-teeth 22 upon the lower face of a setting-wheel 23' staked upon the extreme upper end of the stem 17. Normally, the stem 17 is coupled through the face ratchet- teeth 21 and 22 with the stem 17, so that the clock is normally ready for Winding, which is rendered very easy by the small size of the pinion 12 relative to the size of the main windingwheel 10.

The stem setting-wheel 23 aforesaid is constantly in mesh with a setting-wheel 24 mounted upon a large sleeve-like or hollow stud 25 staked into a yoke 26 and large enough in diameter not only for the passage through it of the reduced forward end of the winding-arbor 13 but also to permit the swinging movement of the yoke with respect to the said arbor'. The said yoke is hung upon a stud 27 mounted in the forward face of an intermediate movementplate 28, which is formed in its lower edge with a clearance-opening 29 for the clearance of the winding-arbor 13 and the fianged inner end of the tubular stud 25 carrying the setting-wheel 24, which is located upon the forward face of the yoke.

The setting-wheel 24 meshes into a pinion 30 turning upon a stud 31 in the outer end of the yoke, the outer end of the said stud having an extension 32 for engagement by the free end of a yoke-spring 33 coiled upon the adjacent movement-pillar 34 and having its inner end 35 hooked over the edge of the front movement-plate 14. The said yoke-spring exerts a constant eiort through the yoke 26 to maintain the mechanism in readiness Jior winding by keeping the face ratchet- teeth 21 and 22 in engagement, at which time the winding and setting stem 17 is in its depressed position.

Vhen the stem 17 is lifted or pushed inward against the tension of the yokespring 33, the yoke 25 is rocked upon its stud 27 and the yoke-pinion 30 brought into mesh with an inner intermediate settingwheel 36 located at the inner end ot a sleeve 37 turning loosely upon a stud 38 mounted in the intermediate movement-plate 23, the outer end of the sleeve 37 carrying an outer intermediate setting-wheel 39 located just in front of the front movement-plate and meshing into the dial or minute-,wheel -i-O et the dial-work, of which only the pinion 41 and the hour or socket-wheel e2 are shown. For the easy assembling ot the intermediate wheels 36 and 39, and the sleeve 37, on which they are mounted, the :tront movement-plate 14 is formed with a clearance-opening 43.

rl`he yoke-spring 33 maintains the mechanism normally in readiness for winding, as described. To set the clock, the stem 17 is pushed inward against the tension of the yoke-spring 33, whereby the upper tace of the wheel Q3, by engaging with the edge of the yoke 26, swings the same upon its stud 27, whereby the yoke-pinion 30 is brought into mesh with the inner intermediate settingwheel 36 at the inner end or" the sleeve 37, the outer end of which carries the outer intermediate setting-wheel 39, which is in constant mesh with the minute or dial-wheel l() of the dial-work. At the same time, the ratchet-teeth 21 are disengaged from the ratchet-teeth 22, thus cutting the windingtrain out of action. Inward pressure upon the stem 17 being maintained, the clock is set by turning the same in one direction or the other as required. The instant inward pressure is removed from the stem 17, the yoke-spring 23 asserts itself to restore the parts to their normal positions of readiness for winding.

By employing a winding-arbor extending between the front and rear movement-plates and by passing the same through ayoke positioned between the said plates, I am enabled to locate the winding and setting stem 17 and its tube 18 suliiciently to the rear of the front of the clock-ease 19 to adapt the same for use with cowl boards of a wide range of thickness.

I claim:

1. In a stem winding and setting clock, the combination with the winding-arbor thereof, of a stem winding and setting mechanism, comprising an oscillating yoke, a hollow stud carried thereby, a setting-wheel turning loosely upon the said stud, and a setting pinion also carried by the yoke and meshed into by the said setting-wheel, the said hollow stud being large enough for the said winding-arbor to pass through it with sufficient play for the oscillation of the yoke.

2. In a stem winding and setting automobile clock, the combination with the case thereof, of a bearing-tube secured in radial relation thereto about midway the depth of the case from Jfront to rear, a winding and setting stem having bearing in the said tube and provided at its upper end with a loose winding-wheel and a fixed settingwheel, means for connecting and disconnecting the said wheels by the longitudinal movement of the stem, a clock-movement located within the said case and having its winding and setting trains positioned for coaction with the said winding and setting wheels upon the said stem.

3. In a stem winding and setting autoincbile clock, the combination with the case thereof, of a radial bearing-tube depending 'from the case about midway the depth thereof, a winding and setting stem having bearing in the said tube and mounting a lined setting-wheel and a loose winding-wheel, a clock-movement located within the said case and having front, rear and intermediate movement-plates, a winding-arbor mounted in the said front and rear movement-plates, and winding .and setting trains, including an oscillating yol'e mounting a setting-wheel and a setting-pinion through the 'former of which the winding-arbor passes without interfering with the oscillation ci the yoke, which is shifted by the inward movement of' the stem to bring its setting-pinion into mesh with a wheel of the said setting-train.

In testimony whereof, I have signed this speciiication in the presence of two subscribing witnesses.
