The transfer gearing comprises a train of gears on vertically spaced shafts, the lowermost shaft having a coupling flange adapted to be driveably connected by a cardan shaft to an auxiliary power-driven axle, and the uppermost shaft being disengageably connectible by clutch means to the output shaft of the vehicle's gearbox. The clutch means comprise a dog clutch sleeve slideable axially by a selector fork operated manually by means including an arm pivotally mounted externally upon the vehicle's gearbox.

Abstract: A control mechanism for controlling the reciprocating movement of a pusher for a picture-holder in a transparency projector of the type in which a rotating shaft serves to reciprocate the pusher during the course of a 360.degree. rotation of the shaft. A continuously rotating electric motor drives the shaft through two gear stages and a coupling member effects the coupling of the motor to the shaft first, through the first stage and then through the second stage.

Abstract: This invention relates to a coupling mechanism with means for disengagement and automatic reengagement of the spool in a spinning reel. The coupling mechanism comprises mating coupling members, one of which forms a driven coupling member supported by the spool and the other forms a driving coupling member supported by a gear which is rotatable by a crank. According to the preferred embodiment, the spool of the reel is, together with its coupling member, rotatably journaled in the spinning reel independent of the unit which comprises the driving coupling member and guide means, and this unit is, in the disengagement position of the driving coupling member, supported completely free from contact in relation to the spool and to elements connected to the spool, with the driving coupling member axially directed for shifting to the engagement position.

Abstract: A wiper blade is pivotally coupled to a rotatably mounted main gear via a wiper arm and abuts the rear window of a vehicle. First and second gear rods are provided in spaced parallel coplanar flanking relation with the main gear. First and second worm gears are affixed to first ends of the first and second worm gear rods, respectively, each on a corresponding side of the main gear. A pivotally mounted support device supports the gear rods with the first and second worm gears on diametrically opposite sides of the main gear. A drive device is coupled to the gear rods for rotating the first and second worm gears. An electromagnetic control device is coupled to the support device for alternately moving the first and second worm gears into coupling relation with the main gear thereby alternately rotating the main gear clockwise and counterclockwise and moving wiper blade in a wide arc.

Abstract: An assembly, specifically a mirror assembly for a motor vehicle, in part angularly adjustable by an electric motor and drive mechanism. A fixed motor drives a worm that is angularly movable through a flexible coupling into selective engagement with one of two nuts to drive adjusting screws that cause a mirror element to pivot about one of two mutually perpendicular axes. The screws and pivot structure for the mirror are integrally formed as part of a mirror supporting plate. The nuts are yieldably coupled to the threads of the adjusting screws to permit slippage between the two when forces exceed the wormed driving force. Operating noise is reduced by a vibration-damping motor mounting and by structure limiting worm engagement with the nuts. Projections are carried by the mirror supporting plate resiliently biased against a fixed support to reduce vibration.

Abstract: An alignment device for machines which, after the shut-down of the machine, keeps the rotor in rotation until it has cooled down in order to avoid damage to the machine.The device comprises a gear element which at a certain number of revolutions of the rotor of the machine engages a gear element of the machine.The device may also initiate alignment from an idle position of the machine.

Abstract: A system for measuring the temperature of the walls of a metallurgical furnace employs a temperature measuring rod mounted for reciprocal movement in an aperture in the furnace wall from an extended position projecting into the interior of the furnace to a withdrawn position. Cyclic reciprocating movement is imparted to the rod by an actuating mechanism, mounted on the furnace wall and including a double acting fluid motor and a servomechanism. The actuating device includes an articulated mounting mechanism permitting the device to be positioned by pivotal movement about two mutually perpendicular axes whereby alignment difficulties on rebuilding the furnace wall are eliminated. Means are also provided for quickly disconnecting the servomechanism to facilitate manual positioning of the measuring rod.

Abstract: A jack for supporting and adjusting the elevation of a trailer tongue comprises a ground support post, having either a caster wheel or foot plate at its lower end, extending downwardly through a jack mechanism housing which is bolted to the trailer tongue. The post can be raised or lowered either by means of a rotatable crank extending from the housing or, alternately, after manual release of latching means in the housing and tilting of the crank, by manually sliding the post. The post has a toothed rack affixed along one side thereof. The mechanism in the housing comprises a pivotally movable support member on which a crank-driven worm and an intermeshing worm gear are rotatably mounted. The support member is spring biased and releasably latched into an upward position wherein the worm gear engages the rack (and functions as a pinion gear) and manual rotation of the crank is necessary to move the post up or down.
