WINDING AND SETTING MECHANISM.

Patented June 9, 1914.

Application filed April 30, 1913. Serial No. 74,567.

To all whom it may concern Be it known that I, WALTER K. Menus, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Winding and Setting Mechanisms, of which the following is a specification.

This invention relates to a winding and setting mechanism for clocks, and is particularly adapted for clocks mounted on auto: mobiles, and the like.

The object of the lnvention is to provide a clock having a dust and Weather-proof case which can remain permanently closed, and having an improved winding and setting shaft or stem, which extends at right angles to the face of the clock, so that the clock case can be mounted 'in an apron, or the like, on an automobile, yet have said shaft always readily accessible for operation.

With the above object in View, the inventionconsists in the improved winding and setting mechanism hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description.

The invention will be clearly understood from an inspection of the accompanying drawing in which-.

Figure 1 is a front elevation of a clock, with parts broken away, having an illustrative embodiment of the invention applied thereto; Fig. 2 is a central vertical section taken on the line 22 in Fig. 1; Fig. 3 is a fragmentary rear elevation; and Flg. 4t'is a fragmentary vertical section, on an enlarged scale, through the winding mechanism.

As illustrated in the drawing, themechanism is embodied in a clock the case of which comprises a cylindrical body-portion 10, closed at one end and open at the other, said open end being closed by a cylindrical glass closure 12, preferably screwed in place to provide a case which is dust and weatherproof, and is particularly adapted for use upon automobiles and the like.

The works of the clock are of well known construction, and as shown comprise a front plate 14 anda back plate 16, suitably spaced apart by pins and mounted within the cylindrical portion of the case 10. A spring drum 18 is mounted on an arbor 20, journaled in the front and back'plates, and the rear end of this arbor is squared to fit a correspondingly shaped hole in a gear 22, said gear being held in place upon said arbor by a screw 2st threaded into the end of thearbor. The'gear 22 is rotatable in a counter clock-wise direction as viewed in Fig. 3, and is held against rotation in the opposite direction by a pawl 25 held pressed against said gear by a spring 27. The gear 22 meshes with an idler gear 26 mounted on a stud 28 carried by the back plate 16, and said idler meshes with a winding 30 on the winding and setting shaft 32.

The shaft 32 is squared at its rear end to fit a correspondingly shaped hole formed in the gear 30, said gear being held in place on said shaft by a screw 34 threaded into the end of said shaft. The shaft 32 is slidably and rotatably mounted in brackets 36 and 38 affixed to the front and back plates 14 and '16, respectively,- A coiled spring 40 surrounds the shaft 32 and bears at one end against the bracket 36, and at its other end against a collar 42 on said shaft. This spring tends'normally to maintain the shaft 32 with its collar 42 in engagement with the bracket 38, and the gear 30 in mesh with the idler gear 26, so that the shaft isnormally always in a position to wind the clock. The shaft 32 extends through the front wall of the lower portion or extension 44 of the clock case, and is provided at its front end with a knob 46, whereby the shaft may be rotated or pulled out to disengage the gears 30 and 2G.

A'gear 50, which may be termed the setting gear, is fast on the shaft 32, and is adapted to be brought into mesh with a gear 52 rotatably mounted on the front plate 14, when said shaft is pulled out longitudinally against the tension of the spring 40. The gear52 meshes with a gear 54 rotatably mounted on the front p1ate,-and the latter gear in turn meshes with a pinion 56 carried bythe center arbor, said pinion controlling the minute hand 57. A pinion 58 is fast upon the gear 54 and meshes with a gear 60, which controls the hour hand 62;

It will be observed that the winding and setting shaft 32 extends at right angles to inclosure at the front end of an automobile, said apron fitting closely about the case of the clock.

In operation, when it is desired to wind the clock, the knob 46 is turned clockwise, the spring 40 acting to maintain the winding gear and the idler gear 26 in mesh.

Whenit is desired to set the clock, the shaft 32 is pulled out sufficiently to disengage the I gear 52 are disengaged, and the winding gear 30 meshes with the idler gear 26.

hat I claim is 1. A clock. comprising a casing having a lateral extension, an arbor to which the main spring is attached, a gear on said arbor and rotatable therewith, gears arranged tocontrol the movements of the hands, a. winding and setting shaft slidably and rotatably mounted within said extension and operable from the front of said casing extending substantially at right angles to the plane of the face of the clock, a winding gear and a setting gear mounted on and movable with said shaft, said winding gear being adapted to be brought into driving relation with the gear on said arbor when said shaft is moved longitudinally in one direction, and said setting gear being adapted to be brought into driving relation with said gears which control the movements of the hands, when said shaft is moved longitudinally in the opposite direction.

2. A clock comprising a casing having a lateral extension, an arbor to which the main spring is attached, a gear on saidarbor and rotatable therewith, gears arranged to control the movements of thehands, a winding and setting shaft slidably and rotatably mounted within said extension and operable from the front of said casing extending at right angles to the plane of the face of the clock, a windingear and a setting gear mounted on am movable with said shaft, said winding gear being normally in driving relation with the gear on said arbor, and

said setting gear being adapted to be brought into driving relation with said gears which control the movements of the llalllds, when said shaft is moved longitudina y.

A clock comprising a casing having a lateral extension, an arbor to which the main spring is attached, a gear on said arbor and rotatable therewith, gears arranged to control the movements of the hands, a winding and setting shaft slidably and rotatably mounted within said extension and operable from the front of said casing extending at right angles to the plane of the face of the clock, a winding gear and a I setting gear mounted on and movable with saidshaft, said windinggear being normally in driving relation with the gear on i said arbor, and said setting gear being adapted to be brought into driving relation with said gears which control the movements of the hands, when said shaft is moved longitudinally, and means for auto- 7 matically returning said shaft to normal position when the setting operation is completed.

4:. A clock comprising a casin having a lateral extension, front and baci plates, a 8 spring arbor journaled in said plates, a gear on said arbor rotatable therewith, an idler gear meshing with said gear, a winding and setting shaft slidably and rotatably mounted in hearings on said plates within said ex- 8 tension and extending at right angles thereto, gearing which is connected to the hands of the clock, a winding gear and a setting gear on said shaft and movable therewith, said winding gear being normally in mesh 9 with said idler, said setting gear being adapted to be brought into driving relation with said hand controllin gearing when said shaft is pulled out longltudinally.

5. A clock comprising a casing having a 9' lateral extension, an arbor to which the main spring is attached, a gear on said arbor and rotatable therewith, gears arranged to control the movements of the hands, a shaft slidably and rotatably mounted within said 11 extension and operable from the front of said casing extending at right angles to the plane of the face of the clock, gearing mounted on and rotatable with said shaft,

said gearing being adapted to be brought 1! into driving relation with the gear on said arbor when said shaft is moved longitudinally in one direction, and adapted'to be brought into driving relation with said gears -which control the movements of the 1;
