Abstract: For a trip odometer comprising a pinion carrier and a pinion spring mounted to the pinion carrier, the improvement provided includes, on the pinion carrier, a mating surface having a thickness, two protruding locators and an underside surface, wherein each locator has a retention ramp operatively associated with the pinion spring to retain the pinion spring in a secured position.

Abstract: An internally illuminated reset counter employs a shaft and counter wheel portions which are manufactured from light transmissive materials. A series of axially spaced grooves in the shaft function to direct light through the counter wheels and axially balance the light intensity.

Abstract: In an electromotive control device having an end disconnect switch, two circular conductive paths are arranged on an insulating support, at least one of said paths being less than an entire circle. Wiper contacts which connect the conductive paths are electrically connected to each other and are connected to a wheel which is driven by a motor, the wheel being mounted coaxially to the conductive paths. The limit disconnect switch and thus a setting element can be manufactured at low cost by the invention.

Abstract: A fuel dispensing unit has a structure providing a plurality of dispensing hoses on each of two sides for dispensing one or more kinds of fuel. The unit has a closed cabinet in its lower portion containing the fuel handling equipment and a pair of vertical hollow end standards, one on each of the opposite ends of the cabinet. A trough interconnects the tops of the standards leaving an open space between the trough and cabinet in which a display unit is mounted to display information on price, volume, etc. All fuel handling equipment is confined to the cabinet, one end standard and the trough. All electrical and microprocessor facilities are confined to the other standard and are sealed from the cabinet, trough and the one end standard.

Abstract: A reset mechanism for an odometer is provided. The reset mechanism operates by means of manually rotatable structure which causes rotation of a reset shaft provided in an odometer. Means are provided for permitting manual rotation of the odometer reset shaft through an angular distance of more than 360.degree. before a stop structure is encountered. Spring means are provided to urge the reset mechanism to a start position after each resetting of an odometer. The reset mechanism requires only about half as much manual rotation as the necessary reset rotation for the convenience and ease of the operator.

Abstract: A counter consists of, to simplify the control of component parts and to improve the productivity, a first frame unit comprising a plurality of digit wheels, a driving gear for a digit wheel of a lower most order, an order shifting-up means and a zero-resetting means, a second frame unit being capable to be snap fitted on the first frame unit and comprising a driving means to be coupled with the driving gear when attached to the first frame unit, and a cover frame unit being capable to be snap fitted on the first frame unit and to show only one line of the laterally lined digits when attached to cover the first frame unit. The second frame unit may be the base plate of the devices on which the counter will be used. The first frame unit may comprise only a plurality of digit wheels, a driving gear for a digit wheel of a lower most order and a zero-resetting button, and the second frame unit may comprise an order shifting-up means and a zero-resetting means.

Abstract: A mechanical preselection counter having: a counter, which has figure rollers and a zero-setting device for the figure rollers; a preselection unit having that number of preselection rollers and transmission of feed gears corresponding to the number of figure rollers, with the transmission gears being drivingly or operatively connected with the figure rollers; and with setting or adjustment elements associated with each preselection roller for setting or adjusting them, the adjustment elements being held in the rest position by spring force, being connected via a coupling device with the zero-setting device of the counter, and being operable with actuating elements. The preselection unit is provided with keying devices, each of which has at least two axially protruding noses which project through openings in the associated transmission gear, are respectively associated with a recess on the preselection rollers, and are loaded or biased by a releasing rack toward the preselection rollers.

Abstract: A zero-restting type of counter comprising a plural number of digit wheels supported on the same shaft and having digit-shift pins, driven gears arranged between individual pairs of said digit wheels, intermittent transmission mechanisms for coupling the individual digit wheels with the corresponding driven gears, digit-shift pins and pinions engaged with said driven gears.Said counter is adapted in such a manner that rotation of said driven gears caused by rotation of said pinions is transmitted by way of said intermittent transmission mechanisms to said digit wheels for the counting operation, whereas said intermittent transmission mechanisms do not transmit rotation and only said digit wheels are rotated when these wheels are rotated for resetting at the zero positions.

Abstract: A presettable counter operated control mechanism employing a spring lock latching arrangement for releasably locking a rotatable control member in different angularly loaded positions. A coil spring connected to the control member encircles a first drum and is selectively frictionally anchored to the drum by a latching arrangement which is releasable by the counter reaching a referenced count to releasably lock the control member at a particular angular position. Two latches provide for releasably locking the control member at two different angular positions thereof, and are tripped at two respective referenced counts, with both latches being tripped at the later reference count. Final release of the control member is operative to terminate counting operation.An interlock between the control member and the wheel presetting mechanism prevents interference with the setting of the counter wheels while the control member is locked and the counter is counting.

Abstract: A low cost resettable counting mechanism comprising an electromagnetic indexing mechanism and a counter stepped by the indexing mechanism having three-piece higher order number wheels with respective unitary molded plastic reset and drive pawl members for connecting the number wheels for counting and resetting purposes. A detent arm integrally formed with the number wheel shaft engages a recess in the counter viewing crystal to hold the countershaft against rotation during counting and the counter shaft is manually rotatable for resetting the higher order number wheels. A clapper and plastic verge of the indexing mechanism interfit to retain them in assembled relationship.

Abstract: Two successive ordinal toothed counter wheels are connected by toothed transfer means to make a tens-transfer once during each revolution of the counter wheel of the lower order. The teeth of the counter wheels and of the transfer means are cut out and hollowed so that the teeth are resilient and dampen impacts thereon during the transfer operation.
