The invention is a universal joint for transferring rotary motion between o shafts whose axes are movable relative to one another. The universal joint includes a generally Y-shaped terminus on either shaft, and a pair of arms on each terminus diverging obliquely away from the axes of the respective shafts. A frame member connected between the termini has a plurality of rods radiating therefrom to engage the arms of the termini. A bearing swivellingly mounted in each arm of the termini defines a through bore for accommodating translational movement of the rods through the bearings.

Device for transferring rotary motion between two shafts

An infinitely variable ratio transmission comprising an input sun gear, a plurality of orbiting planet gears, and an output sun gear. One of the planet gears is engaged with a nominally stationary sun gear. A disc brake retains the stationary gear in place against load forces.

Infinitely variable ratio transmission

An anti-friction worm-wheel assembly wherein the anti-friction elements are ollers carried by the worm element. The rollers sequentially move through grooves in the edge surface of the wheel element to transmit drive forces from one element to the other. Aims of the invention are to achieve rolling contact of the anti-friction elements on the groove surfaces, relatively high load-handling capability, and a relatively simple low cost structure.

Roller bearing gear system

An electrical receptacle containing a multiple number of pin-type connectors, wherein the receptacle housing is a tubular metal member susceptible to manufacture by low cost screw machine procedures. Most surfaces of the metal member are centered on the tube axis, except that a circular flange on the member has a localized flat surface machined thereon for anti-rotation lock action. The receptacle is designed to be secured in place by a concealed nut for protection against theft or vandalism.

Electrical receptacle

A spur gear system wherein each gear comprises two gear sections; gear te in the respective sections are staggered a one half tooth pitch distance. The effect is to achieve a relatively high contact ratio with relatively small diameter gears. Teeth on mating gears are of positive (convex) curvature and negative (concave) curvature to provide an enlarged contact area.

Concave-convex gear pair having staggered teeth

In a military vehicle having small observation windows susceptible to being coated with airborne mud particles when the vehicle is operating off-the-road under adverse climate conditions, it is proposed to provide air pressure mechanisms on the vehicle near the window surfaces. Such air pressure mechanisms are oriented to generate an air curtain in the space between airborne particulates and the window surface, whereby the curtain acts to deflect such particulates away from the window surface.

Prevention of particulate accumulations on observation windows in

A resilient hollow annular frustro-conical roller bearing whose wall thicss varies according to the roller diameter. Any abnormal load placed upon the roller causes an increase area of contact between the roller and the opposing race surfaces. The hollow annular construction of the bearing is such that the load causes the roller to be stressed substantially uniformly along its entire length.

Tapered roller bearing

A hoist that includes a winding drum for a load-lift cable mechanism. The um has two drum sections of slightly different diameter; end portions of the cable are wound in different directions on the drum sections, so that one cable section winds onto a drum section while the other cable section winds off the other drum section. The effect is to provide a very slow net cable motion related to the difference in drum section diameters. The hoist includes a latch mechanism adapted to suspend the load from the boom during certain periods of a load transfer operation.

Hoist

A drive belt formed as a discontinuous belt structure with specially-formed nd connectors. The faces of the end connectors have large numbers of miniature interlockable hooking elements thereon for enabling the ends of the belt structure to be formed into a usable endless drive belt. The belt structure can be cut to varying lengths, such that one belt structure can be used to form a variety of different length belts. The belt ends can be connected together after the belt structure has been installed around a pulley system.

Drive belt construction

An outrigger construction for raising and supporting selected portions of a railer or other wheeled vehicle, e.g. to provide a level stable vehicle attitude while the vehicle is located on sloping terrain. The principal feature of interest is a low-cost power mechanism for operating the outrigger. In one case the power mechanism comprises a winch-cable system. In another instance the power mechanism comprises a level-link assembly.

Outrigger power mechanism

A power transmission that uses inertia forces. The drive member carries a urality of high density rollers that are acted on by centrifugal force. The driven member includes reaction surfaces that periodically move the high density rollers inwardly in opposition to the centrifugal force. As the rollers are moved inwardly they impart energy to the driven member, thereby producing a power transmission action. The reaction surfaces on the driven member are designed so that the system is responsive to speed and load changes.

Inertia transmission

An improved coupling for driven shafts is formed by juxtaposed bores. A se core is disposed within the chamber formed by the bores. A plurality of radially extending splines are formed and used to rotatably fasten the core and the shafts. Adjustment means are associated with the core to move the core from an engaged position between and connecting the shafts for rotation to a second disengaged position within one of the bores.

Shaft coupling device

In a rotary drive system, mechanical means for sensing turning torque gented by the load forces. The sensing means is designed to operate with minimal effect on normal operation of the drive system.

Torque sensor

A variable speed drive that uses cone clutch surfaces, and an adjusting manism for shifting certain ones of the cone surfaces parallel to the cone angle, thereby changing the speed ratio between the input and output members. The engaged clutch surfaces preferably comprise a relatively small diameter male clutch surface engaged with a relatively large diameter female clutch surface, such that a relatively large area engagement is achieved in all adjusted positions of the clutch system. The inventive system preferably includes an intermediate member between the input and output members; this intermediate member has two sets of clutch surfaces interengaged with clutch surfaces on the input and output members to produce a two step speed change from the input member to the output member.

Variable speed drive

An adjustable shim structure for use between shaft-mounted equipments and aft-support bearings, whereby axial play of the equipments is prevented. The shim structure includes two collars having meshed threads enabling the collars to be rotated relative to one another for adjusting the axial length of the collar assembly. The shaft may be connected to each bearing by means of an expansible plug extending within a circular cavity in the shaft; the plug exerts an outward radial force on the shaft wall, thus expanding the shaft into an interference fit with the associated bearing.
