    摘要： A precision adjustable length rod end assembly is disclosed and provides a fastener for mechanical assemblies that eliminates the need for a separate secondary locking device. The device includes a connecting rod, an end connector or rod end, and a lock nut assembly. The end connector threadably engages the connecting rod. The lock nut assembly engages both the end connector and the connecting rod. The threaded engagement between the end connector and the connecting rod enables the rod-end assembly to be adjusted to a precise working length (e.g., as measured along the central longitudinal axis). The lock nut assembly maintains the precision-adjusted working length of the rod-end assembly even when the rod-end assembly is exposed to harsh operating conditions, such as exposure to extreme vibrations.

    摘要： A curled variable radius lever comprises a lever arm 2 of variable effective length that curls and uncurls about a drive axis. In a preferred arrangement the lever assembly has a plurality of rigid blocks 3 articulated together by a chain 4 with link pivots 5 which are affixed to respective blocks 3. Each block 3 has a pair of facing walls 11 and a pair of facing mutually inclined sloping walls 12 which abut when the lever arm 2 is in a curled condition. The lever arm 2 is pulled into the curled condition by a coiled tension spring 13 and restrained in this position by a magnet 9. When it is uncurled the walls 11 abut. The chain 4 then prevents the arm 2 from bending further when a driving force is applied by users to a handle 6. The lever may be used with socket sets, yacht winch, fishing rod reel, a bicycle crank or a jack assembly.

    摘要： A variable ratio rocker arm is provided for use in combination with the valve stem and push rod of an internal combustion engine. The rocker arm has an elongated slot defined between a rod seat and a toothed rack. A fulcrum rod is provided with a toothed sector and a curved sector, with the toothed sector being engaged with the toothed rack portion of the rocker arm. A roller bearing assembly is movably disposed between the rod curved sector and the rod seat, with the roller bearing assembly being rollable along the rod seat. An actuator arm is coupled to the fulcrum rod for simultaneously rotating and translating the fulcrum rod through the rocker arm slot. The operating arm causes the fulcrum rod to rotate and translate along the mating toothing from one point of pivotal engagement, corresponding to a first engine operating condition, to another point of pivotal engagement, corresponding to a second engine operating condition.

    摘要： A curled variable radius lever comprises a lever arm of variable effective length that curls and uncurls about a drive axis. In a preferred arrangement the lever assembly has a plurality of rigid blocks linked together by a chain or spring steel strip. Each block has a pair of walls 11 that face and abut each other in an uncurled, straightened state of the lever arm. The abutment of the walls of the lever arm rigidifies the arm and prevents the arm from bending further in the direction of uncurling when a driving force is applied by users to a handle. The lever may be used with socket sets, yacht winch, fishing rod reel, a bicycle crank or a jack assembly.

    摘要： An arrangement for changing the lever ratio of a two-armed rocker lever, particularly for the transfer movements in a press. The rocker lever is pivotally connected in a lever arm and the starting movement is capable of being tapped by another lever arm. This arrangement includes a frame, a slide guide for the rocking bearing of the rocker lever, a control device, a rotation transmission device and a nut-spindle connection for the sliding movement of the slide guide relative to the rocker lever. The rocker lever, by means of the slide guide, is disposed in a pivot bearing of a support. The support is slidably guided in the frame. The support includes the nut of the nut-spindle connection for interacting with the spindle. The control device, rotation transmission device and the spindle are arranged in the frame, and a device for fixing the position of the pivot bearing in the rocker lever is connected with the rocker lever in an operatively connected manner.
