Abstract: A fan speed indicator is provided including a conventional fan with a pull cord adapted to change a speed at which the fan is running upon being pulled. Further provided is mechanical mechanism for mechanically indicating the speed at which the fan is currently running.

Abstract: The postage meter machine (11) comprises a stator part (12) and a print rotor (13). Two motors (41, 52), a drive (42), a motor switch (45), a battery (46), a logic unit (56), a clock module (58), and two position indicators (48, 54) are disposed in the stator part (12). A catch-stop actuator (24), a catch-stop row sequence (23) with three catch stops of different lengths as well as a date stamp (20) with four counter wheels (16-19) and a coordinated stop-catch device (26-29) are disposed in the print rotor (13). The counter wheels (16-19) are disposed coaxially next to each other and each counter wheel exhibits twelve print positions, which are rotatable stepwise by the catch-stop row sequence (23). Based on the kind of teeth and the length of the cams, either one, two or three counter wheels (16-18) are rotated simultaneously by one position. A coupler (32) connects the one motor (41) to the catch-stop actuator (24) in a certain angular setting of the print rotor (13).

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: A counter mechanism for a postage meter includes a number of sections each having a number wheel (14) repesenting the respective order of accounted value, transfer mechanisms in the form of Geneva gears connecting the number wheels (14) to provide carry-over movements between adjacent sections. A ratchet mechanism is provided in the number wheel (14) to allow rotation of the number drum (16) as a result of an account input from the postage meter, even when a carry movement gear (18) of the number wheel (14) is locked by the Geneva gear. The ratchet mechanism includes an internally-profiled surface on one part (16) having ratchet steps (70) separated by portions (76) of relatively low gradient. Projections (74) are provided on a central member (72) of another part (18), the projections extending substantially tangential to the internally-profiled surface so as to engage in the ratchet steps (70) in the event of attempted rotation in one direction and to stop such rotation.

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: An improved counter wheel assembly comprising an indicia wheel, a reset gear, a reset control mechanism for resetting the indicia wheel to a zero position, a drive gear, and a drive clutch for selectively engaging the indicia wheel to the drive gear. In one form, the drive clutch comprises an elongated pawl engageable with a frusto-conical surface integral with the drive gear and adjacent to and immediately inwardly of the rim of the indicia wheel. In a second embodiment, the drive clutch means comprises a pair of substantially identical V-shaped pawls that pivot in tandem to selectively engage serrations of a substantially cylindrical engagement surface.

Abstract: A resettable register counter wheel assembly with a modified reset gear control mechanism having a modified reset gear pawl pivotal about an axis transverse to the wheel axis for selectively engaging and disengaging a reset gear and a reset control pawl pivotally mounted on the wheel about an axis parallel to and offset from the wheel axis and extending between the reset gear pawl and wheel shaft for pivoting the reset gear pawl outwardly with the shaft and for accurately locking the wheel to the shaft in its fully reset position.

Abstract: An improved "reset" type odometer assembly having counting wheels rotatably supported on a shaft and interconnected by pinion gears therebetween for sequential counting as mileage progresses. A gear wheel between each of the counting wheels is engaged on its right side by a pinion gear which moves with each revolution of the counting wheel located to its right. In turn the gear wheel engages an outer pawl on a molded ratchet spring to cause corresponding rotation of the leftwardly positioned counting wheel. The ratchet spring also has an inner pawl which is engaged by a groove in the shaft when rotated to cause the ratchet spring and counting wheel to rotate during a reset mode of operation. During resetting, the gear wheel and pinion gears are stationary and the outer pawl moves between circumferentially spaced detents in the gear wheel.

Abstract: A fuel delivery pump with resettable volume and cost counters having counter resetting means with a zero detent mechanism for accurately positioning the lowest order number wheels of the counters at zero.
