Abstract: A scissor lift having upper and lower platforms and actuated by a cable reeved so as to pull at least one set of the ends of the scissor together at its extended position and also reeved about a cam roller interposed between the arms and working toward the pivot connection during the portion of the motion in which the lift begins to extend.

Abstract: A brake for a rotatable shaft in which the shaft is joined or is integral to one of a concentric pair of members consisting of an inner and outer members having an annular gap therebetween in which an O-ring is disposed of such a size as to make an interference fit with both members and therefore is radially compressed and deformed in the gap to provide a high static braking torque. One of the members is axially moveable between limiting axial positions, such movement causing a rolling of the O-ring along the gap. A recess is formed in the outer member for interrupting the annular gap and providing free accomodation of the O-ring in one position of axial relationship of the members to permit relative rotation therebetween.
