Abstract: A mount for isolating a vibrating member from its support. In several embodiments an elastomeric element is made up of four components that are preferably bonded to the inclined outer surface of an inner member and the inclined inner surface of an outer member. One of the inner and outer members is bifurcated and drawing the two halves into mating engagement results in the elastomeric components being preloaded simultaneously in compression and shear. The elastomeric element is preferably formed with portions which snub movement in each of three orthogonal directions. The dimensions of the pair of elastomeric components above or below the vibrating member may be different than the other pair since the greater compression strain on one pair of components to maintain maximum design stress levels.

The counter roll is loosely mounted for vertical movement above the plate 12 and the edge of the plate 12 opposite to the edge 26 is unrestricted so that sheets can easily be inserted in the direction of the arrow A. The rolls preferably have polished surfaces and are each chamfered at least on the side away from the edge 26.
Abstract: Automatic braking apparatus for controlling the speed of a vehicle travelling downwardly on an inclined slope. The apparatus comprises a wheel housing, a pair of specially designed wheels mounted in the housing for combined rotary and axial motion, and a rail engageable between the wheels and moveable longitudinally relative thereto. The wheels have tapered camming surfaces which confront one another and annular braking surfaces facing outwardly in juxtaposition with respect to pads of friction material carried by the housing. A load applied between the rail and the wheels forces the wheels axially outward into engagement with the friction pads to retard rotation of the wheels and thereby to limit the relative velocity between the rail and the wheel housing. In one embodiment, the wheel housing is carried by a pallet and the rail is mounted stationary. Wedge means is provided at the lower end of the rail for engaging between the wheels relatively close to their rotational axis to arrest motion of the pallet.
