Abstract: An apparatus for controlling an automatically operated clutch assembly for use with a manually operated power transmission system of an automotive driveline, comprising a fluid operated actuating mechanism for the clutch assembly and an electric control arrangement for operating the clutch actuating mechanism in a manner to drive the clutch assembly at different velocities responsive to various operational conditions of the vehicle when the clutch assembly is to be coupled for starting the vehicle from a halt or making shift between transmission gear positions.

Abstract: A power transfer mechanism incorporated in a multiple path drive system comprises a transfer case disposed between a source of input torque and a pair of drive axles. The torque is transferred directly to the fixed axle and is transferred automatically to the steering axle through a double-acting overrunning clutch when required. The clutch is biased toward one engaged position and is prevented from locking inadvertently in the other engaged position by a direction-sensitive blocking device. Action of this device is timed in order to insure proper blocking.

Abstract: A speed-responsive engaging mechanism adapted for use in a hydrodynamic device to couple turbine and impeller members including a disc secured to the turbine member having a series of cam surfaces thereon formed in apertures in the discs with a series of friction shoe assemblies mounted in the apertures in engagement with the cam surfaces. The friction shoe assemblies engage with the impeller at a predetermined speed of rotation of the turbine member, and the cam means induces a wedging engagement of the shoes with the impeller member. Spring means are provided to retain the shoe assemblies in the apertures, and a roller mechanism is provided in each shoe assembly to provide relatively frictionless relative movement between the cam surfaces and the shoe assemblies.

Abstract: A two-way overrunning clutch is automatically conditioned for operation in either direction of rotation. A plurality of spaced drag springs are in frictional contact with the clutch housing so as to provide balanced radial drag forces on the wedging elements of the clutch, thereby biasing the clutch toward an engaged position thereof. This frictional contact with the clutch housing is reduced by balanced dynamic friction forces developed upon rotation of the clutch.

Abstract: A torque-applying hand tool includes a stepless mechanism for turning an object in a desired direction through an unlimited range by swinging the handle thereof. The stepless mechanism comprises a polygonal shaft and rollers each being placed in touch with each side of the polygon shaft. Each roller is selectively forced to one end or the other of each side so that the polygon shaft may be turned in one direction when the tool handle is turned. At one end of the polygon shaft is formed a socket or box shaft to engage with the object to be turned. In such a tool, the stepless mechanism can be made compact with an unlimited turning range of the object.

Abstract: An electromagnetic clutch has a driving member and a driven member with rollers positioned between opposing non-parallel surfaces on the members. An armature operated by an electromagnet has fingers for moving the rollers into frictional engagement with the surfaces when the electromagnet is energized to engage the clutch and for moving the rollers out of engagement with at least one opposing surface when the electromagnet is deenergized to disengage the clutch.

Abstract: A reversible wrench has a handle integral with a ring shaped head. A reversing mechanism in the head includes a cup shaped member rotatable on a cam block carrying a tool holder. A rotatable control plate on the head has a depending pin engaged in a slot in an end wall of the cup shaped member. The cam block has an upstanding pin engaged in another slot in the end wall and contacting a leaf spring carried by the control plate. Slots in a cylindrical wall of the cup shaped member carry rollers adjacent the cam faces of the cam block. A finger grip on the control plate facilitates rotation of the control plate and rotation of the cup shaped member and rollers on the cam block to effect reversing action between the wrench head and the tool holder.

Abstract: The overrunning clutch includes an integral clutch cage means and sleeve bearing means located in the space between a shaft and a housing. One or more clutch cages integral with one or more annular sleeve bearings may be located in the annular space.The integral clutch cage and bearing serves the dual function of a clutch cage in an overrunning clutch and a bearing to keep the shaft centered in the bore of the clutch housing when the clutch is overrunning.

Abstract: A self-energizing clutch is disclosed, which is of such construction as to enable it to be engaged or disengaged at will, irrespective of the direction or relative speed of rotation, as between the driving and driven components of the clutch. The clutch consists of components or parts which are quickly and easily assemblable, and which are resistant to breakage or damage during the operation of the clutch. A particular feature of the clutch is the creation of a tangential force during operation of the clutch, which exceeds the torque or force between the driving and driven parts of the clutch, in order to disengage the clutch.

Abstract: The invention provides a quiet, reliable and quick acting "no-back" action for synchronous motors utilizing permanent magnet rotors which have minimum power in self-starting and are prone to be erratic in direction of starting. This fallibility arises at least in part from the expense and difficulty of working to the accuracy which would be required to make the motor less uncertain in starting.

Abstract: A roller clutch is provided that is capable of transmitting rotational forces between a first and second machine member. The first member is a cylindrical member such as a shaft, having a smooth outer surface. The second member includes a housing through which the shaft extends. A plurality of rollers are located between the housing and the shaft to transmit rotational forces between the shaft and housing while allowing the shaft to move axially relative to the housing.

Abstract: A pair of bi-directional roller clutches are connected through outer races to separate gearsets and share a common inner race connected to a driven shaft. A shifting sleeve is slidably mounted on the common inner race and is selectively engagable with the retainers of the roller clutches, thereby locking the rollers of the engaged clutch in the freewheeling mode and releasing the rollers of the other clutch, allowing that clutch to drive through its associated gearset.

Abstract: A power transmission capable of transmitting power to both the front and rear sets of wheels of a vehicle, and also to automatically selectively transmit power to the slower rotating set of front or rear wheels. The transmission comprises an inner driving hub which acts through two interconnected sets of overrunning roller clutches to drive either or both of a forward and rear annular driven output member. The forward driven member is connected through a laterally extending chain drive to in turn drive a forwardly extending propeller shaft to transmit power to the front set of wheels to the vehicle. The rear driven member acts through a rearwardly extending propeller shaft to supply power to the rear set of wheels.
