Referring in detail to the drawings, the numeral 5 generally designates a suitable support such as the instrument panel of an automobile on which is conveniently mounted the clock 6 prefe erably of the 8-day type which has a suction pipe 1 extending from one side to which is connected a tube 8 which has its opposite end connected to the suction manifold .9 of the automobile engine I0. The clock 6 comprises a suitable clock casing ll having a mounting and securing flange l2 adapted to be screwed or bolted as indicated by the numeral l3 to the front of the instrument panel with the body of the clock casing disposed in a suitable opening in the panel, so as to dispose the vacuum connection 1 to the rear and out of sight behind the instrument panel 5; The back of the clock casing H is provided with a screened opening I4 to admit air into the interior of the clock casing and into the opening l5 inthe vacuum rotor casing Hi, this casing having a removable cover H in which the opening 15 is located, the cover and casing being held in place on the disk 18 by means of respective fastening means l9 and 20. The disk I8 and the parts attached thereto are mounted within the clock casing II in a suitable manner. Extending from the back of the casing I6 is a bushing 2| forming the journal for the rotor shaft 22 which has on its outward end a pinion 23 and on its inner end a bladed rotor 24 which has blades arranged circumferentially thereon to receive the impelling eifect of air drawn through the opening I5 and directed on to the blades by the angulated nozzle I'5' as shown in Figures 10 and 11. A radially arranged nipple 25 has an 26 communicating with the interior of the rotor casing and to this nipple is connected and extends the vacuum pipe 1. The pipe 1 has a head 21 provided with a reduced opening 28 in the nature of a valve seat in front of which operates the valve 29 which has the fan-shaped part 30 operating directly in front of the opening 28 and the arm portion 3| which extends upwardly and is pivoted intermediate its ends as indicated by the numeral 32 on the said head and has its upper end operatively disposed between

respective pins

33 and 34 on the lower extremity of the enlarged portion 35 of the valve operating and holding lever assembly 36 whichinvolves the lever 31 which is pivoted at the point indicated by the numeral 38 onga bracket- 39 projecting from the disk I8 as shown in Figure 7. Extending from the rear of the lower part of the lever 31 is the L-shaped' arm 49 which is pivoted at its upper end as indicated by the numeral 4| to the lower end of the vertical portion 42 of the bracket 43 which is fastened to the disk IS. A contracting spring 44 is stretched between a pin 45 adjacent the lower end of the L-shaped bracket 40' and an anchor 46 at the upper end of the portion 42 of the bracket 43, the function of this spring being to hold the lever assembly 36 in an over-center position in which the respective one of the

pins

33 and 34 will be operatively engaged with the appropriate side of the arm 3! of the valve 29, so as to hold the valve in an open or closed position, as. the case may bev The vertical part 42 of the bracket 43 has aprojection 47 from which pivotally depends the lever 43 which is pivotally traversed by a pin 49 at its lower end, the pin being secured to the upper end of the lever arm 31 of the device 36. The form of the lever 48 is shown in Figure 21, its pivotal point being designated by the numeral 48' and the lower end thereof being bifurcated as indicated by the numeral 59 to pivotally receive the pin 49; Intermediate the ends of the lever 48 the same is provided with a pin which works in the groove 52 in therotatable and slidable sleeve '53 which works on the shaft 54 as shown in Figure 9, the purpose of this arrangement to be described later on herein. A bracket 55 engages and supports the vacuum connection l on'the disk l8 as shown in Figure 3.

The rotorshaft pinion 23 is in mesh with a gear 56 which has a pinion 56' in mesh with a gear wheel 58 having a pinion 51 in mesh with a gear wheel fifliwhich has a pinion 59, the last being inmesh with a gear wheel 62 having a pinion 6| in mesh with the gear wheel 63' which is on the winding shaft 65' of the spring motor i to be described. The shaft 65' has a pinion 8! which is in mesh with a relatively large gear wheel 80, the gear 63' being on the circumference of the spiral spring containing casing 61. One end of the winding shaft 65 is journaled as indicated by the numeral 68 on the clockworks support 69 and the opposite end of this shaft is journaled' in the disk l8 as shown in Figure 8, and passing through an opening in the parallel clockworks support H. Another support 12 located between the support H and the disk I 8 has fixed thereto the shaft 54 and a washer 13 is disposed on the shaft 54 at the outer side of the support '72 and turning on this washer and on the shaft 54 is the hollow shaft which ine cludes integral therewith at the inner end thereof the relatively large gear wheel 16' in mesh with. the pinion H on the shaft 65'. Turning on the hollow shaft 15 and spaced from the gear wheel 16 by a Washer 18 is thebushing 19 which includes integral therewith the gear wheel which is in mesh with the pinion 8! on the shaft 65, both the hollow shaft and the bushing 19 extending through an opening 82 in the disk l8, all as shown in Figure 8 of the drawings.

On the outer end of the hollow shaft 15 is an arcuate cam 83 which extends a fractional part of the circumference thereof for the purpose of engaging and raising a portion of the axially inward end of the slidable and rotatable element 53 in opposition to the action of the spring 84 which is circumposed on the shaft 54 between a stop 85 and the outer end of the member 53. The member 53 has a radial pin 86 with which a vertical pin 8'! on a flange portion of the bushing 19 is adapted to engage to operate the parts shown in Figure 8.

Referring to Figure 20, it will be evident that the shaft 35 is hollow and has rotatably extending therethrough the shaft 65 to which within the spring casing 51 is anchored one end of the spring 90, the opposite end of the spring being anchored conventionally to the casing, and the shaft 55 being rotatable relative to the casing 61-.

The hollow shaft 65 is anchored, however, as

indicated by the numeral 9| to the spring housing 6'! and to the gear wheel 63, the last being in mesh with the pinion 6! on gear wheel 62. A portion of the shaft 65 is squared as indicated by the numeral 93 so as to non-rotatably mount the portion 94 of the shaft 55 thereon which carries the pinion Bl, the portion 95 of the hollow shaft being anchored as already stated to the spring housing 61.

Supposing the spring 99 to be in wound con dition and the clock is operating on its usual 8- day schedule, and that the valve 29 is in the closed position, and the cam 83 out of operative engagement with the element 53, the, unwinding of the spring 99 will cause the spring housing 61 to rotate in an opposite direction thereby causing the pinion ii to operate the gear wheel 16 and hence the hollow shaft 15 so as to cause the cam 83 to approach operative engagement with the element 53 after the lapse of a predetermined period, so that at the end of said period the element 53 will be cammed out along the shaft 54 against theresistance of the spring 84 and in so moving, move the pin 5| on the lever 48 and thereby swing the lever in a direction to swing the valve operating and holding assembly 36, so that this last operates the valve 29 from the closed to an open position, thereby causing the established suction in the engine manifold,-

supposing the engine to be operating, to communicate with the interior of the rotor casing and cause rotation of the rotor 24, thereby turning the gear 63 on the spring Winding shaft 65,

and thereby effecting rewinding of the springiill.

Thus it is evident that at predetermined intervals of time, shorter than the 8-day operation normal to the clockworks, the vacuum rotor will be operated automatically to rewind the clockworks spring; so that the clockworks are constantly maintained at an 'efliciently wound condition. In view of the fact that the clock runs ordinarily for an 8-day period without rewinding, and in view of the fact that the automobile engine will probably be run for considerable lengths of time during each 8-day period, there is little likelihood that the clock, in the ordinary use of the automobile, will ever become fully run down. The operation of the solid shaft 65 by the operation of the vacuum motor produces also rotation of the pinion 81 which is in mesh with the the shaft of the large gear wheel 80 on the bushing 19, and the turning of thisbushing, as a consequence, will bring the pin 81 into engagement with thepin 86 on the member 53 so as to turn the member 53 to a position on the shaft 54 in which it is out of engagement with the cam 83.

Although I have shown and described herein a preferredembodiment of my invention, it is to be definitely understood that I do not desire to limit the application of my invention thereto, and any changeor changes may be made in the structure and arrangement of the parts, within thespirit of the invention and the scope of the subjoined claims.
