Abstract: A toothed belt drive which is particularly suitable for use in harvesting machines has belt teeth which are trapezoidal in plan and cross-section perpendicular to the direction of motion of the belt. The belt teeth are alternately oriented with the larger side edge of the base adjacent opposite side edges of the strip-like belt. The belt teeth are adapted to engage in recesses in a belt pulley which are complementarily shaped. The recesses in the belt pulley are laterally open adjacent the wider side edge to enable any foreign matter entering said recesses to be readily ejected therefrom.

One end of a guide sleeve is secured to the outer surface of the mounting plate in registry with the opening formed therein and an elongated shank member is slidably supported from the sleeve and projects through the registered openings with one end of the shank member projecting into the sleeve and the other end of the shank member projecting into the transfer case.

Abstract: The tightener includes a contoured strip adapted to bear against the chain or belt and be pivotally mounted on a fixed support member. A wedge member slidably mounted on the support member is elastically biased by a spring and urges the contoured strip against the chain or belt. A guide rod extends through a bore in the wedge member and the spring is mounted on the guide rod. A plate slidably mounted on the guide rod between the spring and the wedge member along one of the edges of the plate and thereby create an eccentric force which jams the plate on the guide rod.

Abstract: A variable pulley transmission in which each pulley is constructed of a pair of flanges coupled to respective shafts, at least one flange of each pair being axially movable relative to the other flange of the same pair, the movable flange being coupled to its shaft by an external spline operative associated with the flange meshing with an internal spline on a drive member coupled to the shaft. The spline connection permits the flange to move axially while maintaining the drive coupling.

Each brace-forming side bar includes a longitudinal web extending parallel to the chain length between the side bar opening and the transverse web. The transverse web of each chain brace has an aperture for reducing a cross-sectional dimension of the transverse web measured parallel to the chain length at least adjacent the longitudinal web of each brace-forming side bar.

Abstract: A mixer having an open top mixing box accommodating a pair of lower augers and a pair of upper paddle conveyors drivably connected to the augers. A power box pivotally mounted on one end of the mixing box is drivably connected to the augers with releasable drive connections. The power box is a motor driven power transmission assembly that can be disconnected from the augers and removed from the mixing box. A movable door associated with the bottom of the mixing box is used to selectively open and close a discharge opening allowing mixed and blended material to be discharged into a conveyor.

Abstract: In taking dial indicator readings as a part of the so-called "reverse indicator" shaft alignment procedure for a turbine-to-compressor drive, the high breakaway torque necessary to initiate rotation of the turbine shaft is supplied by connecting such shaft to power drive means through a power chain. In this manner the turbine shaft may be quickly rotated in small, precisely controllable increments without overshoot, thus saving valuable time otherwise wasted in performing this function manually. Tapered, hollow alignment brackets minimize "bracket sag".

Abstract: A high speed rotor for use with a flywheel comprising a hub, a rim centered with respect to said hub, connecting arms, each in the form of an elongated loop connecting said rim to said hub. The inner end of each loop is centered and maintained against the centrifugal force through a central member belonging to the hub while the outer end of said loop is bearing against the rim, a mass included within said outer end providing elongation of the loop under the effect of centrifugal force to ensure constant contact between said connecting arms and said rim.

Abstract: A transmission ratio variator establishes transmission between a drive shaft and a driven shaft between two orbital systems comprising gear wheels which move concentrically to their respective shafts and where the radii of each orbit are simultaneously variable. The gear wheels are mounted on shafts which are radially displaced in notches made in peripheric wings of sleeves joined to the control elements of the orbits. Each of the shafts of the gear wheels has a truncated thickening contained in a housing provided in each gear wheel. The shafts are axially displaced while blocked in and unblocked from the wheels depending on the direction of the displacement thereof which is controlled by a disc emerging from a ring which is displaced along the sleeve controlled by a double fork whose movement is controlled at will and is produced by conventional means.

Abstract: A drive belt of trapezoidal cross-section is formed essentially of a nonextendible core, which is closed on itself and has a longitudinal groove, and of an assembly of independent riders which are substantially noncompressible in longitudinal direction and are mounted on the core and have a protuberance of corresponding shape housed permanently within the longitudinal groove.

Abstract: A two speed rear wheel hub transmission for BMX bicycles and the like that can be utilized as original equipment or as a conversion kit. High and low speed drive sprockets are mounted with intermediary overrunning clutches on the rear wheel hub of a BMX bicycle with each adapted to be concurrently chain driven by larger diameter high and low speed sprockets commonly mounted on the pedal drive shaft. Both the high and low speed drive systems are normally biased into driving engagement with the rear wheel hub but with the high speed drive system normally overriding the low speed system which free wheels during normal high speed bicycle operation. Downshifting is effected by a manually induced counter-rotational precessing of the rear wheel mounted high speed drive sprocket for selective driving disengagement thereof and automatic, delay free shifting to the low speed drive without effective interruption of drive pedal sprocket rotation.

Each of the side bars presents two end webs spaced apart in the running direction of the chain, extending transverse to the running direction and to the length of the rocker pieces, and each bounding a side-bar aperture. At least one of the end webs has a convex rocker surface projecting into the side-bar aperture.

Abstract: A belt drive arrangement is provided which employs a variator to interconnect a powered drive belt and a belt driven to operate either a transaxle or a transmission of a ground-engaging vehicle. The variator is secured to a pivotally mounted support member. The support member is joined to a speed control shaft which is rotatable in response to the actuation of either a foot pedal or a handle. Rotation of the speed control shaft repositions the variator with respect to idler pulleys associated with the driven belt so as to alter the vehicle's speed. Means are provided to rotate the speed control shaft by actuation of the pedal independently of the position of said handle.
