Abstract: A display system includes a bicycle wheel rotatable about an axle, a lighting device secured to the wheel for rotation with the wheel, and a stand device having an attachment location where the axle of the wheel is attached to support the wheel so that the wheel can rotate relative to the stand device. The stand device includes a drive roller engaging the wheel to rotate the wheel and a motor rotating the drive roller. A distance between the attachment location and the drive roller can be adjusted so that the stand device accommodates different sizes of wheels. The motor and the drive roller can be secured to the stand device at a fixed location while the wheel is mounted to a pivoting portion of the stand device so that gravity pivots the wheel in a direction to engage the wheel with the drive roller.

Abstract: The display device illustrates the ability to maintain a load without the support of compressed air. The display device comprises an expandable base (24) in contact with the floor, a support (32) connected to the expandable base wherein a distal end (30) of the support is substantially, vertically above the base, and a display (17) attached to the distal end of the support wherein the display comprises a plurality of tire sections (12, 14) and each tire section has compression means (16, 18) associated therewith for compressing the tire section.

Abstract: A display device illustrates the ability of a tire which is designed for rain traction to move through a fluid as compared to a standard tire. The display device comprises a sealed rectangular box having a bottom, two sides, two ends and a lid. Pivoting means is associated with the box which is adapted to alternately rotate one end of the box higher than the other. A fluid contained within the box to provide resistance to the movement of objects through the box and means are provided for observing the movement of objects in the box. In the illustrated embodiment, an object made to resemble a standard radial tire, and an object in the shape of a tire with a deep, wide center groove (a rain tire) are enclosed in the box. In its operation, the box is tilted on the pivot so that one end of the box is raised higher than the other, and the objects are observed as they traverse to the lower end of the box.

Abstract: A device for the visual presentation of visually combinable objects which are reproduced on two separate boards which are capable of guided movement relative to each other. One board has an image of a main object with an aperture at a desired location, such that a second object shown on the second board may be viewed through the aperture. For example, the main board may contain a picture of an automobile with apertures where the wheel hubs are located. The second board may contain an assortment of wheel hubs. By manipulating the guide in various directions, different wheel hubs can selectively be made to appear in the aperture on the main board, thereby showing the automobile with different wheel hubs for comparison purposes.

Abstract: Devices for demonstrating the effect that eccentricities in a tire and rim can have when the combination is rotated having a circular member representing a rim mounted for rotation about a center different from its geometric center and an annular member representing a tire with a varying radial dimension is positioned and retained at a plurality of angular positions on the circle member. An indicator operatively associated with the annular member represents the resulting eccentricity of both members. A similar hand-held device represents that combined eccentricity by conveying vibrations through a handle to the operator's hand.

Abstract: An improved apparatus for selectively deflating and inflating a tire mounted on a wheel comprises a valve assembly rigidly and coaxially mounted on a vehicular wheel incorporating a reciprocally movable valve body received in a cavity of a valve housing, the valve body having a plurality of channels for directing gas to gas outlet ports for pressurizing the tire, the valve body moving to a first position to close off a gas exhaust port in the valve housing and a second position to open the exhaust port when pressurized gas to the valve from a pressurized gas source is terminated. The valve assembly includes a valve member movably secured on the valve body alternately opening and closing the gas directing channels as the valve body is moved between the first and second positions. In a driver education system additional power steering and power brake failure assemblies are incorporated.

Abstract: A display for demonstrating puncture sealant tires includes a housing for supporting a tire in an upright position having a base supporting an upstanding frame, a tire restraint on the frame for holding the tire in its upright position, and a pair of spaced apart rollers rotatably mounted on the base for permitting rotation of the tire with respect to the housing to any desired position. A spike member is mounted on a handle assembly which in turn is pivotally mounted on the housing frame for movement between a first non-puncturing position and a second tire puncturing position. A spring in the form of a flat resilient plastic member is mounted on the handle assembly and acts in opposition to the movement of the handle assembly to bias the handle assembly to its first non-puncturing position.
