Abstract: A contact arrangement for interrogating the data and counting values of a wheel revolution counter. The contact arrangement is accessible from the outside at an otherwise hermetically closed housing. The wheel revolution counter is conventionally fastened at a wheel hub of a vehicle in a cantilevering manner. The contact arrangement comprises a contact plate which is fastened axially in the front housing wall together with an insulating bush having a collar serving as a spacer. An adhesive layer fills the gap between the contact plate and the housing. This adhesive layer extends out on the outer surface of the housing and separates the outer surface of the contact plate and the end face of the housing with an insulating layer covering a large surface area.

Abstract: A means is provided for measuring distance travelled by a vehicle having a wheel coupled to a vehicle axle disposed within a vehicle axle housing, with the wheel haivng at least one nonmagnetized metal region which rotates with the wheel defining an orbit through which the nonmagnetized metal region passes as the wheel rotates to advance the vehicle. The apparatus includes an inductive proximity sensor and a counter means. The inductive proximity sensor is of the type adapted for detecting the presence of nonmagnetized metal within a sensing distance and producing an electrical response thereto; it is coupled to the vehicle axle housing a preselected distance from the orbit of the nonmagnetized metal region, so that the nonmagnetized metal region is within sensing distance as it passes by the inductive proximity sensor. The counter is coupled to the inductive proximity sensor for receiving the electrical response and producing a display corresponding to the distance travelled by the vehicle.

Abstract: A hubodometer (10) for attachment to a vehicle's wheel structure for sensing a rotation of the wheel structure and for converting the sensed rotation to a distance travelled. The hubodometer comprises an outer housing (12) having a permanent magnet (28) affixed thereto for generating a magnetic field and a coupler (14) for coupling the housing to the wheel structure such that the outer housing rotates therewith. The hubodometer further comprises an anti-rotation mechanism (16) rotatably coupled within the outer housing, the mechanism having a plurality of components (18,20,22,24,30) coupled thereto, the components being stabilized against rotation thereby. The components include an electronic controller (20) and a plurality of magnetic field sensors (30). The plurality of sensors are disposed relative to the housing such that as the magnet rotates thereabout all of the plurality of magnetic field sensors do not simultaneously sense the magnetic field.

Abstract: A wheeled measuring device having selectively usable and positionable hub elements for use with a plurality of different measuring wheels and corresponding gearing for utilization of a counter to provide different readouts in effecting desired measurements. The hub elements are received in a recess in the housing of the measuring device and retained therein as a result of securing together of separate portions of the housing of the measuring device in the manufacture thereof.

Abstract: A combination hubodometer protective housing and step assembly having a cylindrical metal housing, to which the hubodometer is mounted, and a cylindrical metal adapter, which couples the housing and hubodometer to the axle of a wheel for rotation therewith. The housing and the adapter, and hub assembly and the adapter are coupled by means of threads along the inner and outer surfaces. The hubodometer is mounted to an internal wall of the housing by a threaded stud and nut. The internal wall of the adapter defines an internal chamber which contains lubricant for the vehicle axle. Excess lubricant is allowed to exit the lubricant chamber through vent holes in the housing and step assembly.

Abstract: An electronic hub odometer employs a permanent magnet and a magnetic reed switch for recording the number of revolutions of a vehicle wheel to which the odometer is mounted. A programmable integrated circuit electrically communicates with a clock crystal and the magnetic reed switch to automatically produce data relative to the time, distance and rate of travel of the associated vehicle. The data is stored in a random access memory integrated circuit. An infrared light emitting diode is employed for transmitting the data from the odometer to a remote unit. Information is also transmitted to the odometer from a remote unit via a photo-optical detector.

Abstract: An odometer for use by a golfer in the measurement of distance covered by each shot. The odometer attaches to the wheel of the cart and counts revolutions or parts of a revolution of the wheel through the use of a magnetic head that rotates past a Hall effect sensor. A digital readout indicator displays yards covered.

Abstract: A hub odometer having a protective case adapted to be mounted axially on an axle cap of a vehicle with a substantially cylindrical carrier plate rotatably mounted in the case for supporting a counting mechanism having figure wheels. The shaft of the figure wheels is mounted transversely of the axis of rotation of the case within the carrier plate, and a reduction gearing transfers the relative rotation of case and carrier plate to the figure wheels. At least one ball of heavy metal is provided, the ball being movably positioned in substantially diametrical opposition with respect to the case axis to the figure wheels, the ball being heavier than the counting mechanism.

Abstract: A hubodometer having a wide range of selectable gear ratios so that the same basic structure can be used to indicate distance traveled by wheels of greatly different wheel diameters in either miles or kilometers. The hubodometer has an elongated bore extending through a frame and centered on the axis of rotation of the hubodometer. An odometer helical drive gear and shaft is mounted on the frame transversely to the axis of rotation and removed from the bore in the frame. In assembly of the hubodometer, if a first gear ratio is desired, a support shaft carrying a gear is located within the bore and is fixed to rotate with the casing on its axis of rotation. This gear engages the odometer helical drive gear at a first locus so that the odometer reading is responsive to the rotation of the casing with a first gear ratio. If a second gear ratio is desired, a support shaft having no gear is located within the bore and is fixed to rotate with the hubodometer casing.

Abstract: A hubodometer having a casing supported solely by, and balanced on, its mounting bracket by a ring-like shock mount. Additionally, an odometer mechanism assembly is carried by, and balanced on, a drive-gear shaft located within the casing on the axis of rotation of the hubodometer. The casing is formed by two joined cup-like shells each having a circular flange integrally formed at a mouth of the shell and lying against the flange of the other shell to define an enclosed cavity. An elastic-like gasket is seated upon the joined flanges, and a rigid retainer ring is seated upon the gasket. The retainer ring is fitted tightly to a circular wall of the mounting bracket to nest the casing at least partially within a socket cavity defined by the mounting bracket. The elongated drive-gear shaft has its shaft extremities anchored to opposite bottoms of each casing shell.

Abstract: An odometer i.e. a distance recorder, for a vehicle has a counting mechanism driven by a stepping mechanism which is in turn driven with rotation of a vehicle wheel. The stepping mechanism has a plurality of pawls which reciprocate with wheel rotation and which can advance respective ratchet wheels. For a given vehicle wheel size, one of the pawls is selected to operate its ratchet wheel by a cam means which then disables the or each other pawl from engagement with associated ratchet(s).
