Abstract: The general object of the invention is to provide a rotary type hydraulic pump of simple construction and high capacity and capable of efficient operation at high speed. More particularly the construction provides for varying the capacity of the pump by varying the eccentricity of the pump casing relative to the rotor and for controlling the delivery of the pressure fluid to devices adapted to be actuated thereby. Claim: In a hydraulic pump, the combination of a rotor having a body portion formed to provide an annular space, a ring member revolving with said rotor and fitting within said space and defining with the sides thereof a chamber, reciprocating blades mounted in the body of the rotor and working within said annular "space and defining with said rotor and ring member a plurality of pumping compartments, valve-controlled inlet and discharge passages in the rotor communicating with said compartments, and adjustable means in which said ring member is freely journaled for varying the position of said ring member relative to the axis of rotation of the rotor to vary the output of the pump.

Manufactured by Imperial Bit & Snap Co. - Racine WI

Application was split off from original (viz 1,366,099) to focus on hinged frame. In this design, the guard is hinged from the center, and the knobbed portions that insert in the animal's nostrils are hinged together with a cotter pin used as the "latch." Imperial Bit & Snap Co. ads for REICHERT'S weaners show a hinged frame with the guard hinged from the "outboard" portions as in 1,366,099.
