Abstract: A molded, one-piece adaptor for concentrically connecting a steering wheel and a steering wheel shaft is disclosed. In particular, the adaptor is useful when the steering wheel shaft has a tubular form, but the adaptor may be readily modified in order to connect to a steering wheel shaft having a rod-like form. The adaptor comprises an upper portion and a lower portion. The upper portion has a mechanism for meshing with the steering wheel. The lower portion engages with the steering wheel shaft. If the steering wheel shaft is tubular, the steering wheel shaft slips over the lower portion which has a plurality of tapered ribs which are spaced around and extend axially along the lower portion. These tapered ribs tend to take up any variation in tolerances so as to reduce the rocking between the steering wheel and steering wheel shaft.

Abstract: An improved sucker rod assembly is provided for use in oil wells and the like.

An anchoring component substantially fills the space and bonds to the side portions of the rod to lock the rod end in the space and thereby secure the fitting to the rod. Preferably, the anchoring component has a narrower diameter at the front end than at the rear end thereof.

Abstract: Apparatus for mounting a rotatable component on a rotating shaft using a non-machined torque transmitting intermediate hub member is disclosed. The hub member makes torque transmitting contact with the drive shaft and transmits that torque to the rotatable component through frictional contact at a taper on the drive shaft and at a recessed shoulder of the hub as well as by an external key on the hub periphery and a matching cut-out formed in the rotatable member. There is also a keyway and key between the drive shaft and hub for accurate alignment in assembly and disassembly. A plurality of narrow longitudinally extending rib members are integral with and are supported on the other peripheral surface of the hub member whereby the rotatable member when it is seated against the shoulder on the hub member for the first time mechanically distorts the rib members from their original shape to provide a secure but releasable fit between the hub member and the rotatable component.

Abstract: A thin-walled hollow metal cylinder is rotatably held at its ends between holding flanges which are mounted with a pressure-tight seal on an opposing aligned pair of rotatable hubs. The spacing between the hubs can be adjusted. In one embodiment, the hubs are supported on a hollow pipe arbor and make a pressure-tight seal against it. In another embodiment, one hub is mounted on a stub shaft which is held in bearings and another is held in the head stock of a lathe in proper alignment. In both cases, a pressure medium, air, is supplied to the inner space of the cylinder through the arbor at a pressure of about 0.5 to about 1.0 atmospheres to increase the inherent rigidity of the cylinder. This improves the stability of the cylinder for various processes, such as for photoengraving of the surface of the cylinder to prepare it as a screen-printing stencil.

Abstract: A pivotal mounting arrangement, which may be used for mounting a lamp on a vehicle body, comprises a plastics body having an integral boss provided with a hexagonal inwardly tapering recess therein. A socket element formed from a spring steel sheet has a cup-shaped central portion and six arms extending integrally upwardly therefrom. Outwardly projecting portions extend from the arm and the distance between opposed portions is greater than the corresponding dimension of the recess. A ball integral with one end of a screw-threaded rod is engaged in the socket element before the latter is forced fully into the recess. When disposed in position in the recess, the arms of the socket element are deformed inwardly and hold the ball captive while allowing same to rotate relative to the socket element.This arrangement permits the boss to be formed out of a material which can be relatively rigid because the boss itself need not be resilient.

Abstract: A flexible shaft transmitting the rotational motion of a motor shaft to a rotor adapter is protected from deformation by a shaft protector which connects the flexible shaft to the motor shaft. The shaft protector is concentric about and completely protects the flexible shaft as it extends from the motor shaft to the rotor adapter. The end of the flexible shaft connected to the rotor adapter and the rotor adapter itself are free to move within the lumen defined by the shaft protector. The shaft protector, however, prevents permanent deformation of the flexible shaft by preventing the flexible shaft from bending to a point at which permanent deformation would occur.In one important embodiment of the invention, a rotor adapter is provided with a plurality of grooves which prevent the rotor from jamming on to the rotor adapter.
