摘要： A rotary valve actuator with movable actuator linkage maintained in a constant "pull-pull" tension, includes a sliding canister, rotatable lever, and a return spring substantially aligned in-line with each other. The linear motion of the canister in response to an expanding and contracting pressurized bladder is converted through chain linkage into rotary lever motion. The return spring is connected through respective chain linkage to the lever so the pulling tension of the spring/lever linkage rotates the lever and maintains tension on both chain linkages. Adjustable travel stops are provided. In an alternate embodiment the return spring chain linkage is configured at right angles to the linear movement of the canister. A zero lost motion universal connection includes a splined sleeve matching the splined valve shaft and inserted into a lever bore. A set screw with a flat front end is threaded into the lever and tightened against a flat surface on the splined sleeve exterior.

摘要： A harrow includes a series of sleeves each having a plurality of teeth and telescoped non-rotatably over a rod which is rotatably journaled by laterally spaced bearing assemblies supported by mounting arms which, in turn, are attached to a tool bar. The bearing assemblies include an outer bearing and a generally cylindrically-shaped collar having a circular outer perimeter and a split extending longitudinally along the collar. The collar defines an inner perimeter disposed to receive the elongated rod. At least one radially directed pilot hole for receiving a set screw is formed through each collar. A set screw is threaded through the pilot hole and may be rotatably advanced therein to abut the elongated rod. Reactionary force from the abutment expands the collar at the split to positively engage the outer perimeter of the collar with the outer bearing. The bearing assemblies facilitate rotation of the toothed rod, which rolls over the ground to pulverize and level the soil as the tool bar is pulled forwardly.

摘要： An apparatus for the attachment of an axle (10) to a hub (3) capable of rotating around a rotational axis (2) is provided with a first thread (5) and with a screw (7) with a second thread (8) and a third thread (9), so that the second thread (8) has half the pitch of the third thread (9) and is screwed into the first thread (5). A clamping device of the apparatus consists of a first part (11) and a second part (12) which is screwed via a fourth thread (13) into the third thread (9). By rotating the screw (7) the first part (11) with the screw (7) can be moved in a first direction, so that the second part (12) is at the same time moving at twice the speed in the opposite direction to the first direction. The axle (10) can be clampingly held between the first part (11) and the second part (12) in a wide diameter range so as to be centered relative to the rotational axis (2) by turning the screw (7).

摘要： A device for fixing a roller to a rotary shaft, particularly useful with supply and take-up rollers in a laminator device for printed circuit boards, in which only a single tightening operation is required to fix the roller to the shaft. A support member and a press member when assembled together fit inside an end of the roller. A manually rotatable screw threaded to the press member passes through a hole in the support and presses against a sleeve through which the shaft passes and which is press-fitted inside the support member. Guide plates hold the support member and press member in place.

摘要： A rotatable member is provided with an axial bore that receives one end of an undersized shaft. To fill the space between the shaft and the wall of the bore and to center the shaft in the bore, the portion of the shaft that is in the bore is encircled by a sleeve provided with a longitudinal slot extending outwardly from its inner end. A set screw threaded in the rotatable member extends through the slot and tightly engages the shaft to rigidly connect the rotatable member and shaft together.

摘要： A power transfer assembly having a hub and a circular transfer member provided with a common central axis. A central bore extends along the axis, being defined by opposed, different diameter, concentric inner peripheral surfaces of the central portion. A cylindrical shaft is cradled on one side by the smaller diameter surface and is urged into its cradled condition by spaced radial locking bolts with jam nuts. The smaller diameter surface has a keyway aligned axially with the keyway of the shaft, the two keyways sharing a common key.

摘要： A locking device serving as a key for securing an annular member or hub against axial movement on a shaft and for repetitively self-returning the hub to an angular preset condition and thereafter holding the same against rotation relative to the shaft. The hub has a tapped radial hole through the center of which a transverse slot extends and in which the locking key is received. A set screw is threadedly advanced in the tapped hole to apply increasing pressure on the midportion of the locking key so that spaced parts of the key will contact the slot floor and a flat surface on the shaft creating moments of force which act in offset relation to the shaft''s axis with the result that relative rotation of the shaft and hub will occur until a preset angular or home position is reached at which time the slot floor and the flat of the shaft extend parallel to one another.
