Abstract
A drinking water dispenser for animals for use in suspension-type water supply systems includes a pin received within a vertical bore in a housing and having a lower portion projecting downwardly through the bore, and an upper portion formed with an enlarged head, and overlying weight engageable with an upper portion of the pin, the enlarged head of the pin having a surface engageable with a surface of the housing around the bore. One or both of the latter surfaces are rounded such that the two surfaces define between them a valve which may be opened either by raising the pin or by tilting the pin. In addition, the weight is spaced from the upper portion of the enlarged head of the pin so as to be separated therefrom by a gap when the pin is not tilted or raised.
Claims18
A drinking water dispenser for animals for use in suspension-type water supply systems, comprising:
- a housing formed with a vertically-extending bore through a part thereof;
- a pin received within said bore and having a lower portion projecting downwardly through said bore, and an upper portion formed with an enlarged head;
- and a weight located above, and engageable with, an upper portion of said pin;
- said enlarged head of the pin having a surface engageable with a surface of the housing around said bore to define a valve therewith;
- both of said surfaces being of rounded,outwardly-bulged configuration such that the two surfaces define between them a valve which may be opened either by raising the pin to lift its head off said housing surface, or by tilting the pin to lift a part of its head off said housing surface;
- said weight being spaced from the upper portion of said enlarged head of the pin so as to be separated therefrom by a gap when the pin is not tilted or raised.
A drinking water dispenser for animals for use in suspension-type water supply systems, comprising:
- a housing including a removable insert formed with a bore extending vertically when the dispenser is mounted in suspension;
- a pin received within said bore and having a lower portion projecting downwardly through said bore, and an upper portion formed with an enlarged head;
- and a weight located above, and engageable with, an upper portion of said pin;
- said enlarged head of the pin having a surface engageable with a surface of the housing around said bore to define a valve therewith;
- at least one of said surfaces being rounded such that the two surfaces define between them a valve which may be opened either by raising the pin to lift its head off said housing surface, or by tilting the pin to lift a part of its head off said housing surface;
- said weight being spaced from the upper portion of said enlarged head of the pin so as to be separated therefrom by a gap when the pin is not tilted or raised;
- the upper end of said insert being spaced from the upper surface of said enlarged head to define a ledge engageable with the lower surface of the weight, and thereby to space the weight from said enlarged head to define said gap;
- said weight being formed with a lower portion of cylindrical configuration, and an upper portion also of cylindrical configuration but of smaller diameter than said lower portion and extending through said bore in the upper end of said housing;
- said upper end of the housing being formed with an inwardly-extending lip engageable with the juncture between said upper and lower portions of the weight for limiting the outward movement of the weight with respect to said bore.
