Other obj ects and features of novelty willbe :Qapparent from: the followhigs ecification when read in connection with theaccompanying drawing in which twopreferredembodimentsotthe invention are illustrated byway of example.

Figure L is a, sectionalelevation of .a first embodiment of a driving mechanism according to the present invention.
. Figure 2 is a plan View to Fig.v l.
, FigureBis asectional elevation of a second em- 3 ,bodiment of the driving mechanism.

Eigureh is a lateral elevationpartly in section,
, Figure 6,. Shows an enlarged 1 section across a spoke of the steering wheel and the casingeb tached thereto, containing the watch and its automatic driving mechanism.
The driving mechanism shown in Figs. 1 and 2 is mounted on a frame I having a circular. pening wherein is located a substantially semispherical bearing cup 2 which has a central bottom opening-3. This cup 2 contains three ball bearing rings 4 which are arranged aboveonean- :other and applied on their outer sidetothein- ;--ner cupsurface. A piece it having theform of :a; segment of a sphere is turnably supported in the middle of these ball bearing rings =4 and has a central hole Eithrough which extends a rod "1 which is. connected to the piecev 5 at the center 8 of the spherical bearing surfaces. The rod 1 carries at its lower end swingable weight means in the form of a pendulum bob 3 and extends upward beyond piece 5, the upper end having formed thereon a ballshaped of a ball and socket joint 1, by the intermediary only one thereof will operate.
head constituting-eapart of which a click It is articulated. thereto. This click II] engages a ratchet wheel I I turning with theaxle l2 of abarrel 13 which contains the main or drawing spring of a'wa-tch or other time piece. This drawing spring (not shown) has spiral form and is-secured with its inner, end to theaxle [2, while the other end. is attached to the barrel [3 which is provided witha toothed rim l5 engaging'a pinion of the time piece to be driven and thus transmitting the rotation upon the same. The pendulum 8 must substantially swing in perpendicular plane relative to, the axle l 2 of, the ratchet wheel I l that the click I9 drives the latter by steps. However, on account of: its
suspension and of the impulses acting. thereon, ,the pendulum. may swing parallelly to the axle I2, in which case no driving step will beachievedby click H). To drive ratchet-wheel levenw-hen the pendulum swings parallelly to axle |2,,- a; rod I6 is connected with one end to the. pendulum rod .7 and engages with its other end. aslot, ofone arm I! of .an angular lever whichisturnable about a vertical pin it. The-other arm. l9.-of this lever is articulated to a click 28 which engages the same ratchet wheel ll. This systemof rods or driving mechanism transmits. oscillations of the, pendulum in any direction and of. different amplitudes as driving steps upon the ratchet wheel, whereby, according to the direction-of the pendulum oscillations at the time, both clicks or Shock absorbing stops maybe provided on the insideof, the casing .24 containing the pendulum in order to limit the amplitudes of the latter.
A ring 2a is secured on the bearing cupZ, which narrows the. upper opening, to prevent the. pendulum from leaving with its piece 5, the bearing, when intensive. shocks occur. Where, it.is.desirable that the watch or'like apparatusis-also going, when the vehicle is notused I'ona certain time, there may be provided a hand windingdevice on the watch besides the. self acting; pendulum mechanism which will periorm .I further winding-up as soon as the vehicleis used. .A pawl 23 is pivotally mounted to engage ratchet wheel I I for preventing the latterfrom. rotating backwardunder the action of the tensioned drawing spring. Of course, there is no needoi .a particular barrel iii in the described driving mechanism, as he clicks actuated by the pendulum may directly act upon a ratchet wheel and barrel of the watch or apparatus to be driven.
The described driving mechanism is enclosed in a casing 24 which protects the same. This casing may be secured at any place to the vehicle or a part thereof and will be submitted to the movements and vibrations of that place, which set the pendulum in motion. A watch, for instance, may be combined with this pendulum mechanism and attached to a spoke of the steering wheel of a motor car (Figs. 4 and 5).
The pendulum receives then, besides the ordinary shocks caused by the movement of the motor car, additional impulses through the rocking of the steering wheel. Moreover, it may be very useful that the car driver has constantly a watch in front without being compelled to make other physical movements than to look on the steering wheel. The watch may be detachably pushed on the steering wheel.
In a second embodiment of the invention, shown in Fig. 3, the pendulum 9 is again suspended by means of a semi-spherical piece 5 in the spherical bearing cup 2 on ball bearing rings and is adapted to swing universally in any direction. A disc 25 is secured on said semispherical piece 5, having an upwardly bent rim which is connected by a plurality of regularly spaced pulling strings to a vertically guided click 28 which is resiliently held in engagement with a ratchet wheel 3| by means of pulling springs 30 acting on the horizontally slidable guideways 29 of the click 28. The shaft 32 of the ratchet wheel 31 may be coupled with the barrel of a watch or other apparatus.
Fig. 6 shows a section through a spoke 34 of the steering wheel of a motor car, having a watch and pendulum mechanism attached thereto. The casing 35 may be detachably pushed from oneside on the spoke 34 and secured in its position by means of a strap 31 which is hinged to the casing at 36 and carries a rubber piece 38 which will be pressed against the spoke, when the strap 31 is locked to the casing at 39, while the three other walls of the slit are rigid. The watch or clock 42 is located on the front of the casing and a shaft 40 extends therefrom to the pendulum mechanism 4 I, which is located behind the spoke and winds up the watch movement. The whole apparatus may thus temporarily be removed from its place.
