Abstract: An elastic rotational coupling in which two rotational heads partially embedded in a body of elastic material each comprise a base connected to an end-plate by a neck to define therebetween a groove in which a bead of the elastic material is received. Each end plate has radial notches and an axially outer face which is slightly conical or domed and the groove is shaped to trap said bead therein.

Abstract: A service brake pedal for a stand-up industrial vehicle in which the pedal assumes a level attitude when an operator stands normally on the vehicle with one foot on the pedal and most of his weight applied to the heels of his feet. The service brake pedal is supported by a linkage system which applies a braking force to the service brake system when the operator's weight on the pedal engaging foot is shifted forwardly from his heel. The linkage is arranged to permit essentially all the operator's weight to be selectively applied to the brake system when required.
