Abstract
Abstract This animal watering valve is designed to enable the animal to obtain its own water within its mouth, by biting on it. Primarily, the valve includes a main body which is threaded into a water source pipe, and the main body includes an activating shaft or stem in its bore, which is normally seated by a coil spring. It further includes a rivet which acts as a trigger for urging the shaft or stem angularly off of its seat, to enable water to flow into the mouth of the animal.

Claim 1
Independent Claim
255 words
A side activated animal watering valve, comprising, in combination, a cylindrical main body, means on one end of said main body for attachment to a water supply source, an opposite end of said main body being conically tapered, a wide first central opening in said one end communicating with a narrower second central opening in said tapered end, a shoulder between said openings, a rubber "O"-ring rested against said shoulder, a shaft having an enlarged head at one end being inserted inside said main body, said shaft extending inside said second opening and said head resting against said "O"-ring, said shaft being thinner than said second opening to permit sidewardly tilting, a compression coil spring retained in said first opening bearing at one end against said stem head, and a transverse opening between an outer side of said tapered end and said second opening, and a rivet being slidable in said transverse opening, a button head on the outer end of said rivet, and a flat head on the inner end of said rivet, said flat head being configured larger than said transverse opening to retain said rivet in said transverse opening and being configured to selectively abut said shaft to effect the tilting thereof, said transverse opening being diagonally inclined respective to a longitudinal central axis of said cylindrical main body, and being generally perpendicular to said outer side of said tapered end, whereby when the watering valve is in an operative position the rivet tends to fall away from contact with said shaft.
