ABSTRACT:
An adjustable spacer-cam assembly designed to close gaps which fall within a predetermined range of widths. The assembly includes: a cam plate which has a peripheral increasing-height ramp, a spring washer, and a threaded fastener. Serrations on the underneath surface of the fastener head engage serrations on the upper surface of the washer forming a friction clutch by which the cam plate is driven. Torque is transmitted from the washer to the cam plate by projections on the bottom of the washer which engage in apertures in the cam plate. The spacer-cam plate is driven until the ramp wedges between the members forming the gap causing the friction clutch members to slip.
