Abstract: A wire rolling mill in block form, a so-called wire block, with driving bevel gears which are disposed on a longitudinal shaft and can be selectively coupled by means of clutches with the line shaft and with slow speed supplementary drives for each driving bevel gear, each such supplementary drive becoming operational as the associated driving bevel gear is disengaged, so that shut-down drive lines for inoperative rolls are kept in rotating motion. The supplementary drives are engaged by means of axially slideable driving wheels, more particularly driving wheels of bevel gear construction, which mesh with the driving bevel gears in driving connection only when the associated clutch is disengaged.

Abstract: A reversing double cone clutch drive assembly for a boat comprising a horizontal input shaft, a vertical intermediate output shaft, a first housing provided with an opening in a side wall opposite to the input shaft and an opening in a bottom wall through which the lower end of said intermediate output shaft is exposed, and selectable gear transmission subassemblies attachable to such clutch drive assembly, each subassembly including a second housing with a generally horizontal wall for engaging such bottom wall, said second housing carrying a bearing which mounts an output shaft driven through gear means by said intermediate output shaft said housings being filled interiorly with lubricating oil, in heat exchange relationship with cooling water exterior of said housing.

Abstract: System for positioning and maintaining position stabilization of a mass such as a barrelled gun supported on a base such as a tracked vehicle. The system employs oppositely rotating disks with fluid actuated clutches for moving the gun barrel mass in a single degree of freedom as determined by a deviation from a predetermined setting.

Abstract: Disclosed herein is a marine propulsion device including a drive shaft housing mounted for vertical swinging movement about a horizontal axis relative to a boat, a propeller shaft rotatably mounted in the drive shaft housing and having an axis of rotation, and a propeller carried by the propeller shaft. The marine propulsion device also includes a first bevel gear mounted in the drive shaft housing and in coaxial relation to the propeller shaft, a second bevel gear mounted in the drive shaft housing and in coaxial relation to the propeller shaft, and a clutch mechanism for selectively drivingly connecting the bevel gears to the propeller shaft. The marine propulsion device also includes an annular thrust flange extending from the propeller shaft and for transmitting axial thrust from the propeller shaft to the drive shaft housing.

Abstract: Disclosed herein is a stern drive unit including a stationary housing adapted to be fixed relative to a boat hull and a movable housing mounted on the stationary housing for pivotal movement about a tilt axis which is substantially horizontal when the stationary housing is fixed to the boat hull. The stern drive unit also includes a propulsion leg including a rotatably mounted propeller, an input shaft in the stationary housing transverse to the tilt axis, and an output shaft journaled in the movable housing and having an axis transverse to the tilt axis, generally intersecting the tilt axis, and connected to the propeller.

Abstract: A compact reversible variable speed clutch transmission and differential including a rotable input shaft having a drive gear (76), forward and reverse gears (88,84) engaged with the drive gear on opposite sides thereof, and a pair of selectively operable clutches each having an input (92) connected to an associated one of the forward and reverse gears and an output (94). The clutch outputs are connected to the inputs (110) of a variable speed nutating transmission (120) which includes a pair of independently rotatable outputs (116). The transmission includes a pair of nutating elements (130) each having a surface (132) which is a non-cylindrical surface of revolution. The elements are mounted for rotation by a mounting device (126,128) for rotation and there is included a pair of drive units (134) one for each nutating element, fixedly connecting thereto and to an associated one of the outputs.

Abstract: The invention is an improved clutching means for tapping attachments and particularly adaptable in attachments having free axial float. Direct and reverse drive is provided for by way of planetary gears for driving in direct and reverse drive in the exemplary attachment in which the clutching means is embodied. An adjustment is provided for depth. Spring biased clutch drive members are provided for both the direct and reverse drive providing a narrow, neutral position. Each clutch driver member is in the form of a sleeve having a ball race carrying driving balls interposed between axial splines on a driving part and on the driven spindle. The splines have arcuate side surfaces to confrom to the driving balls providing for substantially frictionless drive in both direct and reverse modes, the balls being free to roll. The splines are especially configurated to facilitate engagement of the balls with them.

Abstract: A clutch mechanism includes forward and reverse driving gears rotatably mounted on the input shaft which has first and second oppositely threaded driving spiral threads thereon. First and second clutch elements threadedly engage the spiral threads on the input shaft. In the neutral position, the clutch elements rotate with the input shaft but when rotation is impeded, the spiral threads drive the clutch elements axially into engagement with the driving gears. An improved shift mechanism includes a yoke having two legs which extend over flanges on the clutch elements. A pin member moves the clutch elements upon axial movement of the shift linkage. Drag is provided for the yoke so that the flange of the clutch element is pinched between the pin member and the yoke to impede rotation of the clutch element. The shift mechanism engages and disengages the clutch smoothly and with the engine torque providing most of the force required for engagement and disengagement.
