    摘要： Overrunning protection for a grinding machine comprising a grinding wheel mounted in a head stock. The head stock is supported on a frame for movement in a direction toward and away from a work rest for a work piece at one end of the frame and a drive for rotating the grinding wheel. The drive is operable to rotate the grinding wheel at a first angular velocity and a second lower angular velocity. The overrunning protection consists of a blocking member operable between a first position permitting engagement of the drive to rotate the grinding wheel at the first angular velocity and a second position permitting engagement of the drive to rotate the grinding wheel at the lower angular velocity. A first sensor senses the position of the blocking member and a second sensor senses the position of the head stock in relation to the grinding position of the work piece at the work rest. The sensors are operatively connected to the drive to control the same in a predetermined manner so that the drive is actuated only if the first sensor senses the blocking member in the second position or if the first sensor senses the blocking member in the second position or if the second sensor senses the head stock in a predetermined position relative to the work piece.

    摘要： A speed governor for a fluid driven rotor having an inlet means for pressurized fluid to the rotor including a valve seat, a valve movable toward and away from the seat to regulate flow of fluid therethrough into the rotor, a chamber on the side of the valve opposite the seat, a supply of pressurized valve control fluid to the chamber so that increasing control fluid pressure in the chamber urges the valve toward the valve seat, and a centrifugally controlled device for increasing the pressure of valve control fluid in the chamber as a function of increasing rotational speed.

    摘要： Apparatus for preventing circumferential overspeeding of grinding wheel comprises spindle with wheel connected thereto and motor assembly connected to spindle for rotating wheel. Motor assembly includes small diameter pulley for rotating large diameter grinding wheel. Assembly also includes alternate large diameter pulley for rotating worn substantially less than large diameter grinding wheel. Movable linkage is located between periphery of grinding wheel and periphery of pulley connected to rotate wheel. Linkage prevents replacement of worn wheel with new large diameter wheel when large diameter pulley is connected to rotate wheel since large diameter pulley operates to position movable linkage at location which is to be occupied by new large diameter wheel.
