Abstract: A self-propelled combine has a power source that is connected to a hydrostatic drive for the drive wheels by means of a belt drive, that includes a pair of coaxial idler sheaves mounted on a freely swingable arm, one sheave being connected to an input sheave by a first belt and the other idler sheave being connected by a second drive belt to an output sheave that drives the pump of the hydrostatic drive. The arm that mounts the idler sheaves is articulated, and a hydraulic cylinder between the two sections of the arm controls the distance between the idler sheave axis and the arm pivot, which in turn controls the tension in the two belts.

Abstract: Method and apparatus for driving an apparatus by means of a drive motor and an infinitely variable transmission comprising an endless transmission member running on at least two V-shaped pulleys having conical sheaves spaced apart a distance controlled hydraulically by means of a pump, which provides the necessary fluid pressure for control of the transmission ratio. According to the invention means are provided for ensuring that the transmission member is tensioned before, and so long as, the transmission is mechanically loaded, using one and the same drive motor. This is achieved by driving the pump by the drive motor and providing a clutch between the drive motor and the transmission, which is hydraulically operated by means of fluid provided by the pump, so that the clutch does not connect the drive and the transmission unless there is sufficient fluid pressure for the transmission to function.

Abstract: A continuously variable drive ratio transmission for motor vehicles is interposed between a prime mover and a drive shaft. When a single foot pedal is depressed the prime mover is brought to the driving condition thereof so as to drive the vehicle. When the single foot pedal is released the drive ratio of the transmission is decreased and the prime mover is brought to the braking condition thereof in response to the releasing of the pedal so as to apply the dynamic brakes on the vehicle. The depression and release of the foot pedal, respectively, rotate first and second cams incorporating cam surfaces representing desired speeds of the prime mover for any pedal setting.

Abstract: A drive mechanism for a spindle of a tool machine, in particular a tool machine having a hob rotatably mounted thereon. Worm gearing is provided for driving the workpiece relative to the hob. Clearance is normally provided between the teeth on the worm and the teeth on the worm gear. Structure is provided for eliminating the clearance so that the drive of the workpiece is a positive drive and no errors exist due to the clearance normally provided between the teeth on the gear and the worm gear. In the particular embodiment disclosed in this application, a second worm is provided and is driven by the first-mentioned worm and worm gearing. The helix angle on the second worm lies outside of the automatic locking area and, in turn, acts onto a braking mechanism.

Abstract: A paper-feeding mechanism of a compact printer is provided. The mechanism has a driven wheel which transmits rotation to a paper-feeding roller and a driving wheel which drives the driven wheel. The driving wheel has first and second sets of gear teeth for engagement with teeth on the driven wheel. The driving wheel is axially displaceable to provide for driving with the first set of gear teeth at a normal paper feed rate and also by the second set for driving at a rapid paper feed rate. A solenoid-operated rate-selection lever serves to select either of the driving speeds. A cam attached to a power wheel which drives the driving wheel serves to return the mechanism from rapid to regular paper-feeding.

Abstract: A variable speed drive system for a carding machine employs a variable pitch pulley assembly that rotates the feed cylinder and doffer cylinder at a constant slow speed as the sliver is made up to the coiler can, and after a predetermined time lapse the speed of the feed cylinder and doffer automatically and progressively increase at a fixed speed ratio from the slow speed condition to a constant high speed condition. If the sliver is not made up properly within the time lapse, the operation of the feed cylinder and doffer cylinder is automatically terminated.
