Filed: 1963-08-29
Abstract: 1,058,245. Grinding. BRINEY MANUFACTURING CO. Aug. 29, 1963 [Oct. 22, 1962], No. 34193/63. Heading B3D.  A dresser arm for dressing a grinding wheel comprises a plurality of parallel extending tool carrying heads 14 secured in longitudinally spaced relation along an elongated supporting frame 12, each head having a tool bar 24 mounted and extending from one end thereof, and means 26 for adjusting the position of the tool bar with respect to the head on which it is mounted located at the opposite end of the head. The frame is secured by bolts 42 to a bracket 40 mounted for pivotal movement so that the frame can be swung in the direction of the arrow 16 to bring the tools 20, such as diamonds, carried by the bars 24 into and out of engagement with a grinding wheel to be dressed. The tool heads 14 are disposed between the side plates 36 of the frame and are adjustable longitudinally of the frame by means of bolts 74 passing through slots 76 in the side plates. Each tool head comprises a body (50, Fig. 4) which is secured by the bolts to the side plates and has a bore (80) in which is received an eccentric sleeve (52) and a cylindrical member 106 having at its lower end (110) a recess for receiving a tool bar (24). Bearing structures (56, 58) having cages locating balls (126) are disposed between the body (50) and sleeve and the sleeve and member under a compressive force so that cylindrical member (106) and tool bar (24) are held without locking means in their adjusted position. The cylindrical member is connected by a key-and-slot arrangement (116, 118) to a disc having a projection (86) engaging a slot (82) in the body, and the sleeve (52) has an axially extending slot (100) at. its upper end engaged by a projection (102) depending from an adjusting member (26) rotatably located in a bore (136) in the upper end of the body (50).

Title: Hydrostatic power transmission system and method of controlling the output thereof
IPC: F16H61/42
Filed: 1965-08-10
Abstract: 1,112,980. Hydrostatic transmission control. CESSNA AIRCRAFT CO. 10 Aug., 1965 [7 Jan., 1965], No. 34240/65. Headings F2C and F2D. In a hydrostatic transmission for a vehicle, lathe or electric generator drive wherein a variable displacement pump 11 is in closed circuit with a variable displacement motor 12 and a control valve 28 supplies pressure liquid to pump and motor displacement adjusting servomotors 18, 19, the servomotors are interconnected so that when operated to increase output speed the pump displacement is initially increased from zero to a maximum and thereafter the motor displacement is reduced from a maximum to a predetermined minimum. As shown, the system is conditioned for neutral and the servo-pistons 20, 24 hold the pump and motor swash-plates 23, 27 in their zero and maximum displacement positions respectively. Leftward movement of the control valve spool 56, to increase output speed, supplies pressure liquid from a pump 29 to a chamber 32 of motor servo 19 and vents a chamber 31 of the pump servo 18. The servo-piston 24 is prevented from leftward movement by liquid trapped in a chamber 33 by a valve 55 and the piston 24 holds open a valve 54 to permit liquid supplied to the chamber 32 to flow through a line 34 to a chamber 30 of the motor servo 18 and move its piston 20 right to increase pump displacement. When the pump displacement attains its maximum value the piston 20 opens the valve 55 whereafter the pressure liquid in the chamber 32 moves the piston 24 left to reduce motor displacement. To decrease output speed the control valve spool 56 is moved right to supply pressure liquid to the chamber 31 and to vent chamber 32. If the motor displacement is below its maximum the valve 54 is closed and the liquid trapped in the chamber 30 prevents leftward movement of the piston 24. The pressure liquid supplied to the chamber 31 flows through valve 55 to the chamber 33 and moves the piston 24 right to increase motor displacement. When the motor displacement attains its maximum value the piston 24 opens the valve 54 wherafter the pressure liquid in the chamber 31 moves the piston 20 left to reduce pump displacement. The hydraulic circuit between the pump 11 and motor 12 includes a pressure relief valve 17 and make-up pump 120. In Fig. 4 (not shown), the piston (20) is permitted further leftward movement to tilt the swash-plate (23) in the opposite direction for reverse drive and springs (71 ... 73) urge the pistons (20, 24) to their neutral positions. An additional valve (75) is moved right to interconnect the chambers (31, 32) and equalize the pressures in the control circuit whereupon the springs (71 . . . 73) neutralize the transmission.
