Abstract

Abstract 1,029,026. Animal drinking appliances. UPJOHN CO. Dec. 11, 1964 [Dec. 23, 1963], No. 50565/64. Heading A1M. An animal drinking fount comprises a body part 12 adapted to be connected to a water supply and having a water supply passage 21 controlled by a check valve 26, and a detachable head portion 11 provided with a passage 54 leading to a valve 60 operable by the animal, the head holding the check valve open so that the passages are in communication with each other when the head is in position on the body part 12 but the check valve closing upon removal of the head. The check valve 26 is spring urged against a resilient seating 23 provided in its housing 13 which fits into the head 11 to define a chamber 52. A pin 43 on head 11 moves the valve 26 from its seating so that water flows into chamber 52 and via passage 54 into a further chamber 53 formed in the head 11 and closed by a valve head 69 carried by a stem 71 which is moved upwardly by the animal to open the valve 69. A pin 72 limits upward movement of the valve head 69.
