摘要： A concrete floor finisher for finishing newly-placed concrete. The machine comprises a rotor hub, a plurality of rotor arms on the hub for rotation about an axis, a blade pivotable on each arm, and a motor for driving the rotor hub. The pitch of the blades is adjustable depending upon the condition of the wet concrete, by a piston and cylinder centrally located about the axis of rotation of the rotor, and a stud connected at one end to the blades and at its other end engaging a portion of the piston to adjust the pitch of the blades in response to the axial displacement of the piston.

摘要： A machine for finishing a flat surface, for example a floor made of cement, concrete, or similar hardened material, includes a chassis supported by at least three wheels arranged to carry the weight of the chassis. A grinding tool, preferably a grinding wheel, is mounted to the chassis to rotate about a vertical rotational axis and to rest on the floor when grinding work is in progress. The grinding wheel is mounted to move freely in the vertical direction relative to the chassis such that the weight of the grinding wheel is carried by the floor, and the grinding pressure is readily adjustable for differing applications.

摘要： The invention relates to an arrangement and method for operating a self-propelled vibratory plate device. The vibratory plate of this device receives its vibratory motion from counter-rotating eccentric parts driven by an internal combustion engine. According to the method, the vibratory plate is stopped with a deadman's handle mounted on the device without the engine stopping. The method is realized with the arrangement of the invention which includes the deadman's handle. The deadman's handle is connected to the engine's fuel control and a centrifugal clutch between the engine and the eccentric parts is engaged only when the speed of the engine is above idle speed. A cam is provided with an interacting support which limits the angular movement of the deadman's handle to a position which corresponds to the idle speed of the engine.

摘要： A hand-operated forward-reverse vibrating plate compactor which includes a vibrating assembly having two counter-rotating eccentrics. The vibrational force generated by the eccentrics is directional and the forward and reverse motion of the vibrating plate compactor is achieved by changing the phase position of the eccentrics relative to each other. This change in the phase position is accomplished smoothly by means of a hydraulic servo control system which permits a continuously variable adjustment of the speed and intensity of the vibration of the vibrating plate compactor to be made.

摘要： The invention is directed to a rotary tool for attachment to a machine for working and smoothing an even surface of a base made of cement, concrete or similar hard material. The machine includes a multi-wheeled vehicle and at least one tool drive shaft arranged on the vehicle. The tool drive shaft defines a longitudinal axis extending perpendicularly to the base to be worked and has a tool holder for holding the rotary tool. The rotary tool includes a plate on which a plurality of cutter-wheel units are mounted about the periphery thereof. Each of the cutter-wheel units includes a frame attached to the plate and axles mounted so as to define respective rotational axes parallel to the plate and substantially parallel to a radius passing through the longitudinal axis of the tool drive shaft. A plurality of cutter wheels is mounted on the axles so as to rotate freely with respect thereto.
