FLUID: 01.001: 7 Patrick McAulifie, New York, N. Y. Application July 22, 1942; Serial No'. 451,911 Claims. (CL 58'-2) This invention relates to new and useful improvements in fluid clocks such as are operated by water or any other desirable liquid.
The principal object of the present invention is to provide a fl'uidclock whichwill operate with 1 precision and which in construction employs only the basis elements necessary in a liquid clock, with these elements assembled in such a manner as to be more positive acting and fool-proof than conventional devices of this character.
Other objects and advantages of the invention will become apparent to the reader of the follow ing description. I
In the drawings- Figure 1 represents a front elevational view of the clockv Figure 2 is a top plan view.
Figure 3 is a section On the line 3-3 of Figure 2.
Figure 4 is a horizontal sectional view taken substantially on the line 4-4 of Figure 1.
Figure 5 is a fragmentary detailed sectional view taken substantially on' the line 55 of Figure 4 and showing the drive ratchet.
Figure 6 is a fragmentary side elevational view of a rigid but yieldably mounted liquid drop operated arm. l
Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes a housing having a front wall a in which is an opening through which a clock dial 6 is visible. At the rear of the clock dial 6 is a shell 1 containing a 12 to 1 ratio gear drive mechanism A. A shaft 8 carrying a minute hand 9 and driven by the pawl and ratchet mechanism partially shown in Figure 5, drives the mechanism A and, in turn, a hollow shaft 8a on the shaft 8, the hollow shaft being provided with an hour hand I 0.
The shaft 8 has a ratchet wheel II thereon with which engage diametrically opposed pawls I2, I3 on side portions 1), b of a drive frame I4 which has an elongated shank I5 terminating in an eye I6 loosely embracing an elongated curved spring arm I1 having its upper end anchored as at I8 to the back wall 0 of the housing 5. A U- shaped stop member I9 embraces the spring arm Il to limit movement thereof and is attached to the rear wall 0.
Stop members, such as pins 20 are provided on the spring arm IT to limit the position of the eye I6 thereon.
A small pan-like structure 2I is at the lower end of the spring arm I1 and overliesthe upper flared end 22 of a stack 23, which opens at its lower end into a liquid receiving chamber724*havinga drain p1ug'25. As is shown in Figure 3, the cylindrical shell l of the clock is mounted on legs 23 supportedby'the top wall of the com partment 24.
Upon the removable top wall llof the housing5is mounted a liquid tank 28 from'which a conduit 29 extends downwardly and through an opening in'the top 21. This conduit 29'extends horizontally under the cover or top 21 and into a spout 30 where it is providedwith a T-fit ting 3I'l-l'aving its discharge end d depending as shown in Figure 3'. This fitting 3| contains a valve'element controlle'd'by a rod 32 extending beyond the spout 30 and through an Opening in one end wall'of the housing v5, where a hand knob 33 is provided.
The conduit 29 adjacent the tank 28 has a valve 34 therein controlled by a rod 35 extending to a convenient lateral position.
It can now be seen, that when the valve in the T-fitting 3| has been properly regulated by the rod 32 so that periodic drops e of liquid will discharge therefrom, these drops will fall onto the pan-like structure 2|, causing flexing of the spring arm I1 and corresponding action of the drive frame I, with the result that the pivotal pawls I2, I3 act on the ratchet wheel II and cause progressive rotation of the shaft 8 which, in turn, drives the minute and hour hands 9, III.
A modification of the spring arm I1 is shown in Figure 6, this view showing a rigid arm Ila havinga pan-like structure 2Ia at its lower end, while its upper end is disposed through openings 35, 36 in concentric rings 31, 38, respectively, and through an opening in a bridge member 39 within the ring 38, beyond which the rigid arm Ila has a head 4|]. The internal ring 38 is secured to the external ring 31 by spokes M, 42, and a coiled compression spring 41 is interposed between the outer ring 31 and the arm Ila within the confines of the ring 38, the spring 41 extending through an opening in the ring 38. Thus it can be seen, that the arm Ila is not only springsupported but adequately guided by the short slots 35, 3B in the rings 31, 38. The shank I5 of the drive frame I4 is associated with this arm Ila in the same manner.
While the foregoing specification sets forth the invention i specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is:
l. A liquid clock comprising a liquid supply tank having a conduit extending therefrom, a valve in the conduit having a discharge opening from which liquid can drop, a yieldable arm having a pan-like structure onto which the drops of liquid can drop and effect movement of the arm, a clock dial, an indicating arm for the dial, a shaft for the arm, and drive means between the yieldable arm and the shaft, said drive means comprising a frame carrying a pair of opposite pivotal pawls and a ratchet wheel on the shaft located within the confines of the frame and with which the pawls engage.
2. A liquid clock comprising a liquid supply tank having a conduit extending therefrom, a valve in the conduit having a discharge opening from which liquid can drop, a yieldable arm having a pan-like structure onto which the drops of liquid can drop and effect movement of the arm, a clock dial, an indicating arm for the dial, a shaft for the arm, and drive means between the yieldable arm and the shaft, said yieldable arm being in the form of a spring having one end anchored.
3. A liquid clock comprising a liquid supply tank having a conduit extending therefrom, a valve in the conduit having a discharge opening from which liquid can drop, a yieldable arm having a pan-like structure onto which the drops of liquid can drop and effect movement of the arm, a clock dial, an indicating arm for the dial, a shaft for the arm, and drive means between the yieldable arm and the shaft, said yieldable arm comprising an elongated rigid member having said pan-like structure at one end, and a compression spring supporting the other end of the arm.
4. A liquid clock comprising a liquid supply tank having a conduit extending therefrom, a valve in the conduit having a discharge opening from which liquid can drop, a yieldable arm having a pan-like structure onto which the drops of liquid can drop and eifect movement of the arm, a clock dial, an indicating arm for the dial, I
a shaft for the arm, and drive means between the yieldable arm and the shaft, said yieldable arm comprising an elongated rigid member having said pan-like structure at on end, and a compression spring supporting the other end of the arm, and guide means for said rigid arm.
5. A liquid clock comprising a liquid supply tank having a conduit extending therefrom, a valve in the conduit having a discharge opening from which liquid can drop, a yieldable arm having a pan-like structure onto which the drops of liquid can drop and effect movement of the arm, a clock dial, an indicating arm for the dial, a shaft for the arm, and drive means between the yieldable arm and the shaft, said yieldable arm comprising an elongated rigid member having said pan-like structure at one end, and a compression spring supporting the other end of the arm, and guide means for said rigid arm, said guide means comprising an annulus having a short slot therein through which the arm is disposed and a second annulus having an opening therein through which the arm is disposed, said spring disposed between the last-mentioned ring and the arm.
