Abstract: A torque multiplier assembly that is portable, compact, and may be easily and conveniently disposed adjacent a nut, bolt or similar threaded elements to removably engage the same. The torque multiplier assembly when so engaged is adapted to exert a first relatively high maximum torque of predetermined value on the nut, bolts or similar elements to initially rotate the same from binding threaded engagement or perform the final tightening of the nut bolt or rotatable element. The torque multiplier assembly is manually actuated by the use of an elongate torque wrench of a type that is commercially available and may be adjusted to supply any one of a number of maximum torque. The desired maximum torque supplied by the elongate torque wrench is relatively low, normally not over fifty foot pounds, and is visually indicated on a calibrated scale that forms a part of the torque wrench.

Abstract: A wheel balancing device for permanent wheel attachment. A rim of the device acts on the wheel periphery to confine same against vibrational movement. A hub and conical disc when acted on by centrifugal force during wheel rotation move axially toward the wheel to radially load the rim and displace same into forceful contact with the wheel periphery.
