Assigned to Racine Tool & Machine Co. - Racine, Racine County WI

Abstract: The object of the invention is to provide a metal sawing machine of the type in which the saw is positively fed into the work during the cutting stroke of the saw and more particularly to improve upon the metal sawing machine of our prior application, Serial No. 132,968, filed September 1, 1926. According to the present invention the use of springs associated with the split nut has been eliminated and the split nut is positively moved into and out of operative position. Further improvements over the aforesaid application are in the arrangement and construction of the clutch control and its association with the manual and automatic control of the saw feeding means. Claim: In a metal sawing machine, the combination with a saw and its frame and means for reciprocating the same, of positive feed means for the saw comprising a screw shaft, a split nut on said shaft operatively connected to said saw frame, means for effecting the engagement and disengagement of the sections of said nut comprising a manually-controlled lever and connections between said lever and the sections of said nut, a pivoted latch engageable with said lever for maintaining said lever in nut-engaging position and including an oscillatory shaft provided with spaced arms, a movable member carried by said lever and manually operable independently of the movement of said lever to engage one of said arms to release said latch, and a member movable with the saw frame and engageable with the other of said arms to release said latch when the saw reaches a predetermined position.

Assigned to Racine Tool & Machine Co. - Racine, Racine County WI

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.
