摘要： An applicator (10) for applying seamless flooring material to a subfloor (11) including a chassis (12) steerably mounted on wheels (14, 16, 18). A dispensing hopper (28) on a frame (30) is towed behind the chassis (12) from a shaft (74, 76) on a steering column (72) and enabled to move in three dimensions independent of the chassis (12). The hopper (28) is supported by hopper wheels (296, 298) with the flooring material dispensed out of the hopper (28). The height of each side of the hopper (28) is independently adjustable on each side by screw-threaded rods (302, 304) and is not disrupted by lifting the hopper (28) out of operation.

摘要： Designed to improve the quality of the float finish on a partially hardened cement floor, especially along the border areas adjacent to walls, the machine comprises a rotor, embodied as a disk (1) supporting a set of trowel blades (2) accommodated in corresponding radial slots (27) and angularly adjustable, an engine (11) and a speed reducer (5) the output shaft (4) of which carries a sliding collar (21) with a projecting flange (22) positioned to bear on the ends of a set of crank levers (23) keyed to the innermost ends of the shafts which carry the trowel blades (2); the machine also comprises an idle spacing element (24) the hub (24a) of which is coupled rotatably with the outer surface of the sliding collar, and with a coaxial sleeve (19) affording a projecting flange (18) engaged by the forked end members of a rocking lever (17), the remaining end of which is attached to an adjustable rod (15). The machine can be used to float finish concrete and cement floors laid in premises of any given description.

摘要： A concrete finishing machine having a rotatable trowel blade assembly (11) and a mechanism (27, 29, 33) for controllably adjusting the pitch of the trowel blades (15) relative to a wet concrete surface (19) on which the blades rest. Manual pivoting of a control lever (25) controllably adjusts the trowel blade pitch and, in doing so, automatically increases or decreases the amount of blade surface contacting the concrete surface (19), and correspondingly lowers or raises the machine relative to the surface (19). The contacting blade surface supports the machine's entire weight. A special counterbalancing apparatus that includes, for example, a compressed coil spring (51), biases the control lever (25) so as to compensate for the machine's weight and permits an operator to adjust the blade pitch with substantially less force than otherwise would be required.

摘要： A finishing machine comprises a motor mounted on a support frame and connected to a drive shaft and two or more finishing heads and an impeller fan driven by the drive shaft via a serpentine belt drive which rotates the finishing heads in opposite directions. The impeller fan impels dust from the grinding heads into a rear vacuum manifold and the support frame has rear wheels the height of which is adjustable by means of an hydraulic cylinder.

摘要： A concrete finishing apparatus (10) and method for smoothing and flattening partially set-up concrete to a close-tolerance surface includes a movable unit (12) that is movable and supported at a partially set-up concrete surface and at least one rotatable ring finishing member (20) mounted to the movable unit. The rotatable ring finishing member is positioned at the concrete surface and rotatable to engage and finish the surface of the partially set-up concrete to a higher quality, closer-tolerance flat and level concrete floor surface. The apparatus may include a pair of rotatable ring finishing members that may be rotatable in opposite directions to enhance the floating and finishing processes and to transport any cement paste, sand, small aggregate, or concrete mix residue forward with the rotatable ring finishing members working surfaces to cut high areas and fill in any low areas as the concrete finishing apparatus moves over the partially set-up concrete.

摘要： A brake (100) of a concrete finishing trowel (10) responds automatically to the cessation of drive torque delivery to the rotor to actively brake the trowel's drive train, hence inhibiting or preventing frame rotation. The brake (100) preferably takes advantages of inherent characteristics of an inclined gear (82), such as a worm of a gearbox, to permit an internal component of the gearbox to shift automatically upon the cessation of drive torque therethrough from a brake released position to a brake engaged position. In the case of a worm gear-based gearbox (40), the worm (80) is configured such that reaction forces that are normally generated by the delivery of drive torque therethrough shift the worm to release the brake during normal trowel operation. These forces are eliminated in the absence of drive torque transfer, permitting the worm to shift to a brake engaged position.
