Abstract: A clutch brake arrangement for farm working machinery etc., includes a boss parallel with an output shaft extending from an engine mount, a rotary member rotatably mounted on the output shaft, a pressure plate mounted on the boss in such a manner that it is slidable along the axial direction of the output shaft, the plate being provided for pressing a lining plate rotatable with the rotary member, a brake spring resiliently disposed between the engine mount and the pressure plate, and cam plates opposed to each other through the pressure plate and a cam ball and fitted over the end of the boss by a retaining ring. In this way, the arrangement can be brought near the engine mount, whereby the length, as viewed in the axial direction of the output shaft, and hence size of the arrangement can be decreased.

Abstract: A clutch brake arrangement for farm work machinery or other equipment comprises a rotary member rotatably attached to an output shaft extending through a cam plate mounted on an engine mounting. A pressure plate is mounted on the cam plate in such a manner that it is movable along said output shaft. A brake spring is provided to bias the pressure plate toward the rotary member. A lining plate is disposed between the rotary member and a clutch disc rotatable with the output shaft. A clutch spring is provided to bias the lining plate toward the clutch disc to engage it with the pressure plate. The pressure plate is moved toward the cam plate against the brake spring, so that the lining plate is engaged with the clutch disc and, thereafter, is spaced away from the pressure plate. A plurality of projections are discontinuously formed on the peripheral portion of the pressure plate which is outside of its braking plane.

Abstract: A clutch brake arrangement for farm work machinery or other apparatus is provided comprising a rotating member rotatably mounted on an output shaft projecting from a member fixed to an engine mounting, a pressure plate disposed on said fixed member in such a manner that it is movable in the direction of the output shaft, a pressure spring for biasing the pressure plate toward said fixed member and urging the plate upon an operation rod, a clutch plate interposed between a disc plate rotatable integrally with said output shaft and said fixed member, and a clutch spring for biasing the clutch plate toward said disc plate, whereby the inner peripheral edge of said clutch plate is rotatably engaged with said pressure plate, the peripheral edge of said clutch plate is slidingly engaged in the direction of the output shaft of said rotating member, and said clutch plate is separated from said fixed member when said pressure plate is urged by said operation rod against said pressure spring, and is thereafter urged up

Abstract: A centrifugal clutch brake for farm work machinery or other apparatus is provided comprising a member attached rotatably to an output shaft extending from a member fixed to an engine mounting, a clutch plate disposed between a drum rotatably together with said output shaft and the fixed member, a disc plate mounted on the clutch plate in face-to-face relation to the fixed member, a brake plate disposed between the disc plate and the clutch plate toward the fixed plate, a clutch spring provided for biasing the clutch plate toward the drum, and a fly-weight mounted on the clutch plate. The fly-weight is adapted to be expanded by a centrifugal force until it is placed in engagement with the drum. With such an arrangement, when a push is given to the brake plate against the pressure spring, the disc plate is spaced away from the fixed member with subsequent disengagement of the brake plate out of the disc plate, thereby urging the fly-weight upon the drum .

Abstract: A clutch-brake device for cutting machines disclosed herein has a first cover secured to the bottom of the engine case and a second cover rotatably fitted over an output shaft which is connected to an engine and projects from the first cover. A cutting blade is secured to the bottom of the second cover. A brake plate and a clutch plate are provided immediately above and below a disk mounted on the output shaft for rotation therewith, and are connected together at their peripheries. The clutch plate is urged by a spring toward the disk. One of the clutch plate and the brake plate has a plurality of guide pieces projecting from the outer periphery thereof and slidably fitted into a plurality of axial recesses formed in the second cover. A brake lever is provided on the first cover immediately above the brake plate for rotation and axial sliding movement.
