  • Patent number: 4251090
    Abstract: A sole plate construction for a ski. The sole plate is pivotally secured to the ski about a centrally located pivot axis with respect to the sole plate. Front and rear holding parts are provided on the ski to hold the sole plate in a fixed position relative to the ski during a normal downhill skiing position of use. One of the holding parts incorporates a locking element which yieldingly holds the sole plate in a longitudinally aligned relationship relative to the ski. In order to minimize the number of fastening elements required to hold the components to the ski, the holding parts are secured to centering plates, each of which has an elongated slot therein receiving the pivotal support part pivotally holding the sole plate to the ski. Any flexing of the ski will cause the centering plates to shift with respect to one another and to the pivotal support part. A single fastening element serves to secure each centering plate to the ski.

  • Patent number: 4245851
    Abstract: A ski brake made of spring wire and pivotally secured to a mounting plate which is in turn secured to the upper surface of a ski. The spring wire contains multiple bends therein with the spring wire being pivotally secured to the mounting plate about two axes which are spaced in the longitudinal direction of the ski. One of the pivot axes is centrally located on the mounting plate and movably supports the spring wire therein for movement toward the tip and tail of the ski. The other pivot axis of the ski brake is defined by a pair of laterally spaced axles which are located forwardly from the first-mentioned pivot axle and each are housed in bearing structures which will facilitate a pivoting of the axle about a vertical axis. This pivotal movement about the vertical axis can be by either making the axle housing the spring wire therein loose or by mounting the spring wire in a member which is in turn pivotally secured to the upper surface of the mounting plate.

  • Patent number: 4241931
    Abstract: A discarded automobile tire is utilized as a part of a mobile toy or exercising device. A tire riding vehicle is provided with a base support extending parallel to the space between the two tire beads of the automobile tire. Two spaced axles extend normal to and are supported by the base and in turn support spaced apart rollers which ride on and are supported by the automobile tire beads. Flanges are associated with the rollers, are disposed inside of and abut against the tire beads, and thus maintain the rollers against lateral displacement from the tire beads. A platform is supported by the axles and supports a rider on the vehicle. A platform is preferably provided for each foot of a rider and carries a spring loaded brake and also pole supports. Poles so supported may be used by a rider to guide, steer, and brake the vehicle. The poles are spring loaded and normally in non-braking positions. Rollers or tongues are employed resisting release of the vehicle from the automobile tire.

  • Patent number: 4240483
    Abstract: A wheel for lessening rolling resistance and other forces that retard the rolling of the wheel consisting of a circular wheel rim, a hub member positioned concentrically within the wheel rim and a spoke arrangement connecting the wheel rim with the hub member for storing and releasing externally applied energy to provide propulsive torque to the wheel. The spoke arrangement is formed from a single strand of wire that is wound around the hub and is extended to the rim to form spoke loop portions. As the wheel is rolled over a supporting surface, each spoke loop portion is flexed as the portion of the wheel adjacent thereto engages the roadway. As that portion of the wheel approaches a point where it breaks contact with the roadway the spoke portion closest thereto unflexes imparting a torque on the wheel in the direction in which it is being rolled.

  • Patent number: 4236459
    Abstract: An open top gondola railway car of depressed center design having stub sills and an end panel at each end of the car body which slopes outwardly and upwardly from an intersection with a generally permanently closed bottom having horizontal plate portions and at least one centrally located depressed curved portion in cross-section. Wheeled multi-axle trucks adjacent each end are provided with the horizontal plate portions extending over them. An upwardly directed step portion located intermediate the ends of the curved portion and reinforced openings having a smoothly curved perimeter in the horizontal plate portions located over the wheels, provide an increase in the clearance distance between the bottom and any concave or convex contoured portion of track upon which the car is located. The openings may be circular with rings or flanged conical members bolted to them to provide the reinforcing. The sloped ends have support sheets directing lading forces exerted on the ends to the stub sills.

  • Patent number: 4227588
    Abstract: An apparatus which can automatically start and warm up a vehicle by means of a remote control signal. A remote control transmitter sends a signal of a predetermined frequency which is detected by a receiver located in the vehicle. The receiver produces an output signal in response to receiving the remote control signal which starts the operation of a starting circuit to provide an electrical energizing signal for operating the vehicle starter as well as a gas flow signal for sending a supply of gas to the vehicle carburetor. An operating circuit also starts which provides an electrical operating signal to the vehicle ignition system to continue the running of the vehicle once it is started. The operating circuit continues for a predetermined amount of time whereupon the car stops operating after it is sufficiently warmed up.
