Abstract: A brake assembly is universally mountable to any one of several different types and sizes of hand trucks. The complete brake assembly includes a brake control handle that is removably attached to the upper frame of the hand truck; a brake bar assembly having a base removably attached to the axle of the hand truck, and a horizontally extending brake bar with brake pads on its two ends adapted to engage the wheels; a cam mechanism for depressing the brake bar; and a cable coupling the brake control handle to the cam mechanism.

Abstract: A normally engaged (dead man's) brake for a manually operable pallet truck. A spring-biased, levered cam is housed within a wheel subassembly frame. Two wheels that are axle-mounted to the frame contain integral brake drums and are mounted so as to circumferentially superimpose the drums over brake shoes which are pivotally mounted to the frame. Under normal, non-operational conditions, the levered cam forces the brake shoes into registry and contact with the drums, thereby conditioning a brake-engaged mode. A manual control lever is cable-connected to the frame in a fashion to enable overcoming the spring biasing of the levered cams, thereby releasing the brake. The moment manual force is released, the levered cams return to the normal, brake-engaged mode, thus effecting the invention's purpose.

Abstract: An improved parking brake is provided for use on a movable machine, in particular a lift truck with an elevating platform. A pin-type brake is provided with a buffered slide mechanism which engages and disengages a slotted disc mounted on a wheel to brake the machine while not in use. The buffered slide mechanism provides a delay for the slide mechanism when the slide and apertures in the slotted disc are not in precise alignment, and automatically engages or disengages the brake when the slide and disc apertures are in alignment. The brake also reduces wear on the internal cylinder components by providing a slide supported at its ends by guides and pivotally linked to the cylinder mechanism.

The combine further includes a pair of manually-operable brake assemblies, each of which is disposed for cooperation with one of the rear wheels. Each of the brake assemblies is movable between a non-engaged and engaged position relative to the associated rear wheel, in the latter position of which it at least frictionally retards rotation of the associated rear wheel.

Abstract: Disclosed herein is an improved hand truck having stair climbing capabilities of the general type employing a pair of star-like plates journaled on a main axle and carrying a plurality of stub axles on the projecting legs of the plate with each axle carrying a wheel to facilitate ascending or descending stairs. The type of truck in question operates so that one of the wheels will be in contact with the lands of two adjacent steps at all times to avoid jarring and to facilitate movement. The improvement disclosed includes the provision of braking means which will prevent "free-wheeling" of the plate so as to effectively slow up movement of the truck particularly when descending. The brake is operated from the handle end of the truck and releasably engages the main axle to either permit or prevent "free-wheeling" of the star-like plates to thereby selectively inhibit movement of the truck.

Abstract: A hand truck having a flat, rigid, annular disc coaxially fixed to each of a pair of outboard wheels between the hand truck frame and the wheel. A respective caliper having two parallel fingers which hold respective brake pads is mounted on the hand truck frame adjacent the periphery of each disc so that the two fingers are disposed on either side of the disc for forcibly pinching the disc between the brake pads. The calipers and associated mounting hardware are specially structured so as to minimize the space between the inside of the wheel and the outside of the frame. To ensure even wear of the brake pads the wheels are mounted on bearings which permit axial sliding of the wheels on their axle so that the discs float between the two caliper brake pads.

Abstract: A brake assembly is disclosed in which a first pivoted lever receives and transmits brake actuating force to a second pivoted lever via rollers which transfer force between the two levers at a point which, due to the geometry of the second lever, moves progressively closer to the pivot point of the first lever and farther from the pivot point of the second lever as force is applied to the first lever.
