Abstract
Abstract An automatic waterer which utilizes a self closing valve which is vertically installed and in which spring and hydraulic pressure work to seat the valve and in which a pivoted beam which utilizes a weight of substantial mass at one end and which carries a drinking bowl on the other end is provided. As animals drink from the bowl the mass overcomes the weight of the liquid in the bowl and lowers the beam on the valve actuator so as to replenish the liquid supply in the bowl thus rebalancing the beam and allowing the valve actuator to return to the closed position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
237 words
An animal waterer comprising: a housing member; a balance beam pivotally supported from said housing so as to pivot about a substantially horizontal axis; a drinking bowl supported on said balance beam on one side of said axis of pivot; a weight supported on said balance beam on the other side of said axis of pivot; a supply valve for supplying fluid to said drinking bowl supported from said housing and having a valve actuator engageable by said beam and actuated thereby when the balance beam is moved by said weight, said valve actuator being mounted on said other side of said axis of pivot and being spring loaded to the closed position such that it is closed except when said balance beam depresses said valve actuator; and a cover member formed with a depression and an opening formed in said depression detachably mounted on said housing member over said drinking bowl and said drinking bowl available through the opening formed in said depression wherein cam members are attached to said cover member, cam engaging means mounted on said housing member and engageable with said cam members to join said cover member to said housing member, and latch means attached to said housing means and movable to a first position to lock said cover member to said housing member and movable to a second position to allow said cover member to be removed from said housing member.
Claim 2
Dependent Claim
237 words
An animal waterer comprising: a housing member; a balance beam pivotally supported from said housing so as to pivot about a substantially horizontal axis; a drinking bowl supported on said balance beam on one side of said axis of pivot; a weight supported on said balance beam on the other side of said axis of pivot; a supply valve for supplying fluid to said drinking bowl supported from said housing and having a valve actuator engageable by said beam and actuated thereby when the balance beam is moved by said weight, said valve actuator being mounted on said other side of said axis of pivot and being spring loaded to the closed position such that it is closed except when said balance beam depresses said valve actuator; and a cover member formed with a depression and an opening formed in said depression detachably mounted on said housing member over said drinking bowl and said drinking bowl available through the opening formed in said depression wherein cam members are attached to said cover member, cam engaging means mounted on said housing member and engageable with said cam members to join said cover member to said housing member, and latch means attached to said housing means and movable to a first position to lock said cover member to said housing member and movable to a second position to allow said cover member to be removed from said housing member.
Claim 3
Dependent Claim
25 words
A waterer according to claim 1 comprising fluid conduit means attached to said valve and having an outlet for discharging fluid into said drinking bowl.
Claim 4
Dependent Claim
23 words
A waterer according to claim 1 comprising motion limiting means mounted on said beam to limit its motion relative to said housing member.
Claim 5
Dependent Claim
27 words
A waterer according to claim 1 comprising means for adjusting the position of said weight relative to said beam to adjust the moment caused by said weight.
Claim 6
Dependent Claim
22 words
A waterer according to claim 1 comprising a heater mounted in said housing for preventing fluid in said drinking bowl from freezing.
Claim 7
Dependent Claim
209 words
An animal waterer comprising: a housing member; a balance beam pivotally supported from said housing so as to pivot about a substantially horizontal axis; a drinking bowl supported on said balance beam on one side of said axis of pivot; a weight supported on said bAlance beam on the other side of said axis of pivot; a supply valve for supplying fluid to said drinking bowl supported from said housing and having a valve actuator engageable by said beam and actuated thereby when the balance beam is moved by said weight, said valve actuator being mounted on said other side of said axis of pivot and being spring loaded to the closed position such that it is closed except when said balance beam depresses said valve actuator; and a cover member formed with a depression and an opening formed in said depression detachably mounted on said housing member over said drinking bowl and said drinking bowl available through the opening formed in said depression and in which a beam latch is pivotally attached to said housing member and movable to a first position to engage said beam to lock it relative to said housing member and movable to a second position so that it does not engage said beam.
Claim 8
Dependent Claim
209 words
An animal waterer comprising: a housing member; a balance beam pivotally supported from said housing so as to pivot about a substantially horizontal axis; a drinking bowl supported on said balance beam on one side of said axis of pivot; a weight supported on said bAlance beam on the other side of said axis of pivot; a supply valve for supplying fluid to said drinking bowl supported from said housing and having a valve actuator engageable by said beam and actuated thereby when the balance beam is moved by said weight, said valve actuator being mounted on said other side of said axis of pivot and being spring loaded to the closed position such that it is closed except when said balance beam depresses said valve actuator; and a cover member formed with a depression and an opening formed in said depression detachably mounted on said housing member over said drinking bowl and said drinking bowl available through the opening formed in said depression and in which a beam latch is pivotally attached to said housing member and movable to a first position to engage said beam to lock it relative to said housing member and movable to a second position so that it does not engage said beam.
