A flexible power transmission means comprising an assembly of a pair of spaced, generally parallel chains, each constructed of a plurality of sets of interleaved links. Each set is joined to its next adjacent set by a pin, each pin serving both chains. Generally trapezoidal-shaped load blocks are located between the chains and having cut-outs in the sides locating the chains. The load blocks are generally contoured at their edges to fit into the V of a pulley and are disposed between the chains. The load is carried by the chains and its pins. The load blocks are longitudinally positioned with respect to the chains by the chains' pins.

Metal transmission belt

A power transmission belt comprising an elastomeric body and longitudinally spaced, lateral stiffening members extending substantially the width of the body. The stiffening members may be of multiple piece construction and joined to a longitudinal reinforcing tension member in the body of the belt. Additional edge pads may be attached to the stiffeners at the edges of the belt. The belt of this construction is especially adaptable for use to transmit power in variable pulley drives and the like.

Power transmission belt

An endless power transmission belt having a reinforcing and tension member, such as a cord or cloth strip, to which are attached, stiffener and about which is an elastomeric material. The stiffeners for providing lateral stiffness may be finger-like, at least in parts, and adhesively attached to the reinforcing and tension member or molded therearound. The stiffening means may be individual, side-by-side parts or a continuous member.

An endless power transmission belt having a reinforcing tension and lateral stiffening means, an endless one-piece plastic member. The member is formed with alternate rod-like portions and hinge portions and the entire member is bonded to the elastomeric body of the belt. Such belt is especially adaptable for transmitting power in variable pulley drives and the like.

A variable pulley system incorporating driver and driven pulleys in which a flange of the driver pulley has a rim to receive the belt or the like connecting the pulleys in the final drive ratio of the pulleys.

Variable drive

A constant angular velocity joint for the transmission of rotational movements between two shafts includes a pair of driving members, each coupled to a shaft, one driving member having a plurality of generally equally spaced pivot means connected obliquely thereto so as to overlie the driving member, the other driving member being generally cylindrical and having a converging portion extending therefrom with a plurality of open ended, generally radial spaced slots therein, the spacing of which corresponds to the spacing of the pivot means. Each pivot means is received in one of said slots for relative movement with respect thereto depending on the angular position of said driving means.
