Abstract: A variable speed winch including a uni-directional drum rotatable initially by the clockwise motion of a handle in a clockwise sense only. The winch also includes a gear selector including a control plate rotatable with respect to the drum into an extreme clockwise position wherein a first gear ratio is selected. The gear selector further includes ratchet structure, splined to a shaft rotatable by the handle.

Abstract: A spring power device is provided which includes a multiturn coil spring having its inner end anchored to a rotatable shaft and its outer end anchored to a large drive gear which is mounted to rotate freely on the shaft. An electric motor is connected to rotate the shaft. Whenever the coil spring winds down, a microswitch senses the radial outward movement of the outermost turn thereof and connects a battery to energize the motor to wind up the inner end of the coil spring at a fast rate. The drive gear is controlled to release the power stored in the coil spring to drive a load.

Abstract: A speed shifting mechanism for a pneumatic wrench or nutsetter comprises a planetary gear arrangement in the drive mechanism of the wrench in which the planet gear carrier is connected to the driver clutch member of a torque responsive clutch and the planetary ring gear is mounted in a one way clutch to provide for unidirectional rotation of the ring gear. The torque responsive clutch is of the sloping tooth type and the driving clutch member is connected to a piston having opposing faces and fitted in the tool housing to form opposed fluid chambers. Pressure fluid is admitted to one of the chambers at a controlled pressure to act on the piston for holding the clutch in the engaged condition. Movement of the driving clutch member at torque causes pressure fluid at the controlled pressure to be vented and the opposite chamber to become pressurized thereby acting on the clutch to disengage and enable the planetary gear arrangement to become operative to reduce the output speed of the wrench.

Abstract: A heavy duty dog clutch has co-axial driving and driven shaft elements each with a toothed connection to an intermediate sleeve that is axially displaceable to make and release one of said connections. The toothing of the releasable connection is helically formed so that a given direction of driving torque tends to screw together the helical toothing. One of the shaft elements is capable of axial displacement by the reaction to said torque in the helical toothing and this causes a pair of abutment surfaces on the shaft elements to bear against each other to engage the clutch fully.
