Abstract: A web of metal is unwound from a coil and cut into longitudinal strips which are directed into corresponding loops and then through tension units to a set of strip rewind units each having a horizontal mandrel. Each rewind mandrel has a driven center shaft which supports independent mandrel sections for receiving and rewinding the separate strips into corresponding coils. Each mandrel section has a set of collapsible coil support shoes and is driven by a corresponding air actuated clutch. The air pressure to each clutch is precisely varied by a control system which senses changes in the corresponding loop in the steel strip so that each steel strip is rewound independently of the other steel strips. Thus all of the steel strips are rewound at substantially constant tension into corresponding rewind coils independent of variations in thickness of the strips and in elongation of the strips due to internal stresses.

Abstract: A belt carriage is movable along a vehicle body mounted track to move an occupant restraint belt between an occupant restraint position and a stowed position permitting occupant ingress and egress. A plastic drive tape is attached to the carriage and has perforations which mesh with a toothed tape drive gear for driving the drive tape and carriage back and forth along the track. An electric motor and a speed reduction gear unit are connected to the tape drive gear by a clutch which couples with the drive gear only when the electric motor is energized so that whenever the electric motor is not energized the occupant may grip the belt carriage and manually move the belt carriage and the drive tape to move the restraint belt between the occupant restraint and stowed positions independently of the motor. The clutch is preferably a centrifugal clutch in which clutch pawls are thrown outwardly by centrifugal force to engage with the tape drive gear when the motor is energized.

Abstract: A freewheeling clutch assembly wherein pawl members are mounted for pivotal movement in one of a driven and driving member of the clutch assembly and wherein ratchets are formed in the other member. When the driven member overruns the driving member, pivotal movement of the pawls causes their disengagement with the ratchets and the clutch will freewheel. When the driving member commences again to overrun the driven member, resilient annular means interposed between the members will cause the pawl members to be pivoted back into their torque transmitting position.

Abstract: The clutch contains a spring for pulling the arm of the control lever on the stop and an additional auxiliary spring connected with a roller. While the control lever strikes on the stop, the roller moves toward one lever arm so that in a further rotation of the parts, the roller (30) is lifted within a slot while additionally tensioning the auxiliary spring. While the tension of the main spring decreases, that of the auxiliary spring increases correspondingly, so that the control lever is held with sufficient tension on the stop and machine vibrations during the striking or operation can be made harmless or damped.

Abstract: A clutch particularly suitable for machine drives in agricultural implements including a clutch hub, a clutch sleeve, and spring-loaded dog members operative to engage and disengage within tapered recesses in said clutch sleeve for controlling torque transmission through the clutch. The recesses are formed with a circumferential dimension large enough to accommodate therein movable control members together with engagement heads of the dog members. The control members cooperate with the dog members within the recesses to effect disengagement of the clutch when a maximum torque is exceeded and to automatically effect re-engagement of the clutch upon achievement of a nominal speed whereupon the dog members, which are spring-loaded in the clutch hub, may automatically re-engage within the recesses.

Abstract: A deadbolt lock mechanism of the single cylinder type is disclosed having a latch bolt which is movable between extended and retracted positions by means of a lock cylinder at one side thereof. A thumbturn, together with manually movable coupling control means for controlling the coupling between the thumbturn and latch bolt are located at the other side of the mechanism. In the bolt retracted position, the coupling control means is movable between coupling enabling and disabling positions to condition the coupling for operation of the latch bolt by the thumbturn in the enabling position thereof, and for disabling such latch bolt operation by the thumbturn in the disabling position. Consequently, the latch bolt is operable by the lock cylinder in any position of the thumbturn and coupling control means, whereas the thumbturn is enabled for operation of the latch bolt only when the coupling control means has been moved into enabling position.

Abstract: A remote control steering attachment for a steering wheel wherein a driving motor is releasably attached to the steering wheel by means of a cross member adjustably bolted to the steering wheel. A clutch is interposed between the driving motor and the steering wheel so that the steering wheel can be operated when the unit is declutched and the driving motor is not being used. A remote control is used for controlling the driving motor and thus turning the steering wheel from a location distant from the steering wheel.

Abstract: In a disengaging clutch, catch members are spring-biased into a position for transmitting torque between a clutch hub and a clutch sleeve. Each catch member has a wedge-shaped cam cooperating with a similarly shaped cam on a control ring. The control ring is held against the catch member by a spring and it is rotatably mounted on the clutch hub. When a predetermined torque is exceeded the control ring moves axially against the action of the spring and the catch members move radially from the torque-transmitting position to a floating position. By rotating the control ring, the catch members can be displaced from the floating position into a re-engaging position before returning to the torque-transmitting position.

Abstract: A tractor driving system has an overload coupling in which a hydraulic system disconnects a driven output shaft upon overload. Also, the system includes a gauge which is visible to the driver station as well as adjusting features that enable the transmitted torque to be preselected and monitored. In one aspect, fluid in the ducts, chambers, etc., which normally form a constant volume space, holds a plunger in a recess between two coupling parts. Upon overload, the plunger end is forced out of the recess and hydraulic fluid is displaced through a relief valve until fluid returns the plunger, either by opening the circuit to a pump, or by spring biasing a piston in the system with a set screw. In the meanwhile, one part can rotate with respect to the other part. In another aspect, two sets of gears can be alternatively used to drive the output shaft at different speeds. The gear sets can be operated by a double acting plunger having two bevelled ends.

A driver operable control rod is formed with a cut out portion forming an wedge surface including a large inclined first section near the bottom of the cut out portion and a small inclined second section. The first and second sections are selectively engageable with a free end of the cam plate upon axial movement of the control rod to urge the brake pawl to disengage from or engage with the parking gear.

Abstract: A fail-safe, velocity-discriminating centrifugal clutch having a biased, ion-transmitting pawl element displaceable at speeds at or above a predetermined threshold value to an engagement position with a driven ratchet assembly. Under conditions of missing or malassembled parts, clutch operation is in the fail-safe mode with no transmission of rotary motion. In the engaged position, no centrifugal force generated by the pawl element is applied to the ratchet assembly. This feature, plus the radial contact between the pawl element and the ratchet assembly, allows operation between misaligned input and output shafts, even at high rotational speeds.

Abstract: A mechanism for driving a computer form web along a predetermined path includes a ratchet wheel having two sets of oppositely facing teeth, mounted on a support shaft for rotation.

Abstract: A device is disclosed by which two paired controls in an aircraft flight control system, such as pitch controls, or the roll controls, which are ordinarily operated in coordination by the pilot by use of a single operating control may, when the control on one side of the airplane is damaged and jammed, accomplish a disconnect of that side, and so free the opposite side control for operation. The aircraft can often be flown with just the one side control in commission, if freed from the opposite side. The device is in the nature of a bell crank, and the disconnect means is in the hub thereof.Also disclosed is a novel bi-directional sensor incorporated in the input arm of the bell crank, and which gives an indication to the pilot when the linkage to the corresponding control surface, or the control surface, is damaged and jammed. This sensor has application other than in aircraft control systems.
