Abstract: A braking device for braking and depositing two-dimensionally extending workpieces, particularly cardboard packaging, which are fed so as to be spaced apart from one another, the workpieces are fed to a braking roller whose circumferential speed is slower than the feed speed of the workpieces, and at least one cam presses a workpiece passing the braking roller against the braking roller at the end of the workpiece in the feed direction and reduces the speed of the workpiece.

Abstract: A brake actuating assembly includes a cam member that has first and second cam surfaces. A first piston in a first hydraulic circuit is selectively enabled to axially translate the cam member from a released position to an actuation position while an actuation piston moves friction surfaces into engagement with a rotor to effect a brake application. During a brake application, pressurized fluid is diverted away from a second piston in a second hydraulic circuit that is later enabled to return the cam member to the released position. A resilient assembly selectively engages the second cam surface to obliquely move the cam member toward the actuation piston during a brake application. An electrically actuable valve supplies pressure fluid that acts on and moves the resilient assembly away from the second cam surface and thereafter allow a second hydraulic piston to return cam member to the released position.

Abstract: An improved hardened insert and brake shoe adapted for use in bi-directional backstopping clutches is disclosed. The inserts are formed from a base material of high speed alloy tool steel, which is relatively inexpensive and easy to machine. The base material is formed into the desired shape for the insert, then hardened and tempered by conventional processes to achieve a desired hardness. Then, a coating of titanium nitride is applied to the insert by a physical vapor deposition process or a chemical vapor deposition process. The titanium nitride coating provides a very hard surface to the insert, which permits the insert to be used in the backstopping clutch. In an alternative embodiment, the brake shoes are formed in the manner described above, and no inserts are used in the clutch.

Abstract: A mounting assembly for a roller blind comprises a housing in which is rotatable a drive wheel by a flexible member such as a chain. A roller blind is connected to a shaft which carries this drive wheel and is, therefore, rotatable with the drive wheel for raising and lowering of the roller blind. A friction-type brake wheel is jointly rotatable with the drive wheel in the housing and has an outer periphery against which radially engage rollers carried on a pair of pincher-type levers whose one ends are pivoted together and whose other ends are interconnected by a screw device so that the force which the rollers exert radially on the friction wheel can be controlled. This force determines the braking effect between the shaft and the housing so that the blind carried by this mounting assembly remains stationary in any set position.

Abstract: A braking system for engaging a vehicle's wheel including a first braking step to retard the vehicle and a second braking step to halt the vehicle while still avoiding skidding.

Abstract: A braking device for sleds, according to which rollers are used as braking elements which by means of an actuating element are moved from a non-braking position into a braking position while being pressed against the surface of the sliding path for the sled. According to a preferred design of the invention, pairs of rollers are employed with the rollers of each pair having different diameters.

Abstract: A braking device for retarding and controlling the speed of moving objects such as cartons, pallets and the like, travelling down an inclined roller conveyor system. The device comprises a primary roll journalled in a housing and having a peripheral surface actuable by a said moving object and a secondary roll journalled within the housing actuable by the primary roll. The secondary roll is loosely journalled in a bracket pivotally mounted on an axle coaxial with the primary roll and is biased by an adjustable pressure plate having a bevelled portion at one end to an at-rest position in proximity to the primary roll. Rotation of the primary roll under the weight of an object travelling thereon rotates the secondary roll by frictional interengagement against the bias of the pressure plate whereby the secondary roll becomes wedged between said primary roll and the pressure plate bevelled portion for retarding the rotation of the primary roll.
