Abstract
This fluid operated clock comprises a support stand which includes a shaft providing a pivot mounting for an oscillating housing, and which carries a reservoir above the housing for supplying fluid to housing inlet openings. The housing is partitioned to provide outer fluid compartments, having fluid discharge openings, and an intermediate compartment mounting an adjustable balance weight above the pivot center. The housing oscillates between defined limits and includes an actuating pin engageable with a pawl and ratchet assembly to rotate a wheel carried by the shaft and having an indicator ring attached.
Claims10
A fluid clock comprising:
- a. support means.
- b. pallet means including opposed fluid compartments each having an inlet opening and a discharge opening and a balance weight means,
- c. pivot means mounting said pallet means to said support means for oscillative movement about a pivot center disposed below the combined center of gravity of said pallet means including the balance weight means,
- d. a pair of limit means operatively engageable by said pallet means to determine the oscillative travel of said pallet means,
- e. fluid supply means disposed to supply fluid to one of said inlet openings when the pallet means engages one of said limit means and to supply fluid to the other of said inlet openings when the pallet means engages the other of said limit means,
- f. indicator means mounted in movable relation to the support means, and
- g. drive means actuated by the pallet means to move the indicator means in time indicating relation.
