Abstract: A reset device (7) for the digit rollers (3) of a counter has a positioning spring (22) developed integrally on a shift drive bridge (9), the positioning spring being adapted to engage by means of a detent projection (21) into detent recesses (17-20) of the side surfaces (13-16) of a position setter (12). In this way, the position setter (12) passes in particularly reliable manner into each of its four possible positions.

Abstract: An odometer having a reset mechanism with a single spring that has a torsion section acting on the reset mechanism to bias pinions into engagement with the odometer wheels and a compression section for biasing the pinions into a predetermined axial position relative tot he odometer wheels.

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: A roller counter, which can be reset to zero position via its axis has, for the purpose of stepping its digit rollers, a lock pawl swivellably supported on a side wall of the digit rollers for being swivelled around a pin. A pestle, serving the purpose of zero setting, is supported for swivelling movement around a second pin on the digit roller and cooperates with a stop on the axis. The locking pawl and the pestle each are spring-loaded to a predetermined degree by a leg of a leaf spring bent to V-shape. The leaf spring is held on the digit roller by means of a mounting including walls accompanying both legs of the leaf spring at the inner side and at the outer side and contacting the legs according to a surface-to-surface contact.

Abstract: A simple mechanical counting device is disclosed. The counting device includes a simple zero reset mechanism which enables the counter to be easily reset to zero by the use of a finger of the human hand.

Abstract: A reset mechanism for a cyclometer register employs teeth formed on an axially resiliently urged shaft to engage abutments formed on cyclometer drums to permit resetting of the cyclometer drums. The teeth are normally maintained out of alignment with the abutments by resilient urging of a spring and are manually displaced into engagement for resetting. Carry pinions on a pinion shaft are urged into mesh with respective gearwheels on the cyclometer drums by a pair of springs. During resetting, the pinion shaft, with its pinions, is displaced outward. When the pinions are displaced outward, one or more teeth on each pinion enter a window disposed adjacent thereto in the frame of the cyclometer register. The windows lock the pinions into a predetermined angular position which enables proper mesh to be made with the gearwheels at the conclusion of the resetting operation when the springs again urge the pinions into meshed engagement.

Abstract: A tape counter with the structure where a substantially U-shaped frame is provided with digit wheel engaging grooves vertically notched on both side plates thereof, a digit wheel shaft axially mounting digit wheels is fitted on both ends to said engaging grooves, a lens member is integrally formed on a cover assembled over the frame to magnify and display digits on the digit wheels, positioning projections are integrally formed on the internal surface of the cover on the center line of the lens member, the reading line of the digit wheels is aligned with the center line of the lens member by engaging the projections into the digit wheel shaft engaging grooves, a side play adjusting spring having a slit extending upward from the lower end thereof to allow the digit wheel shaft to pass therethrough is inserted between the side plates and the highest order digit wheel and the upper end of the side play adjusting spring is caught with the internal surface of the cover.

Abstract: A preselection counter having a switch-off counter which is adapted to actuate a desired function when a quantity of this function determined by a preset value has been reached includes presettable indicating means having number rollers adapted to have the preset value set therein and to retain this setting through repeated cycles of operation of the switch-off counter. The presettable indicating means enable continuous display of the preset value during operation of the counter with the preset value being transferred from the number rollers of the switch-off counter by a sensing wheel mechanism which is operatively interposed therebetween and which may be repeatedly reset to the preset value on the preset counter after each cycle of operation of the switch-off counter without requiring changes in the preset value in the presettable indicating means.

Abstract: A fuel pump register cost counter having a transfer pinion permitting count transfers from the units to the tens counter wheel at a substantially predetermined maximum torque through a torsion spring connection between input and output gear sections of the transfer pinion and which prevents transfer overtravel and oscillation and provides for accurately locating the tens counter wheel.

Abstract: In a setting device for presettable counters, a number of indicating rollers are arranged with symbols on their circumferential peripheral surfaces. Connected to each indicating roller is a ratchet wheel and an adjusting wheel. A switching device for each roller permits it to be moved in a step-by-step manner and otherwise to be locked in position. The switching device includes a switching pawl for engaging the ratchet wheel and moving the roller, a fixing lever for locking the adjusting wheel and roller in position, a control pawl and a key for displacing the control pawl. The control pawl is spring-biased against the actuating movement of the key. The control pawl displaces the switching pawl and the fixing lever in response to its displacement by the key.

Abstract: A counting device of the kind having coaxial number wheels each with a reset cam and transfer pinions mounted on a shaft which is displaceable relatively to the number wheels the pinions being located between successive number wheels with each pinion meshing with gear teeth on an adjacent number wheel and adapted to engage drive means on the other adjacent number wheel so as partially to rotate the number wheel with which it is in mesh. Reset fingers are provided which are together rotatable about a common axis respectively to engage with the reset cams to reset the number wheels, the reset fingers and transfer pinions being located, prior to resetting, respectively out of engagement with the reset cams and in engagement with the gear teeth on the number wheels. A reciprocably movable actuating member is also provided to effect resetting of the number wheels during movement in one sense and upon movement in the reverse sense is repositioned for subsequent resetting action.

Abstract: A register designed to count and display cost on a gasoline dispensing pump. The register has a 100 cent wheel which is driven by a stepping motor. As the 100 cent wheel rotates it biases a spring which, after the 100 cent wheel has completed a revolution, incrementally drives a dollar register wheel. Likewise, as the dollar wheel rotates it biases a spring which, after the dollar wheel has completed a revolution, incrementally drives a 10 dollar register wheel. The energy stored in the springs is also utilized to reset the register to zero, such that all of the power utilized to both drive and reset the register is supplied by the stepping motor.

Abstract: A counter comprises a body housing a set of discs which are freely rotatable on a sleeve and which have numerals on their peripheries. A series of drive plates are keyed to the sleeve and interleaved with the discs. At one end of the set of discs a spring-loaded collar also keyed to the sleeve urges the drive plates and discs into frictional engagement. The sleeve is rotatable with a reset wheel while the collar is driven by a star counting wheel through an orbital drive arrangement. The orbital drive arrangement may include a further collar having outwardly directed projections thereon which engage an abutment carried by a resilient arm, the abutment and projections restraining the further collar against rotation during counting. Each disc has a set of first abutments and a second abutment on its periphery.
