Abstract: A device for accurately measuring the position of a traveling block in a drilling rig or the like which is supported by means of a cable wrapped around a drum winch assembly. A pneumatic sensor coupled to the drum provides a predetermined number of output pulses per revolution of the drum. During the paying out of a first layer of cable from the drum, the sensor pulses are coupled to a first pneumatic counter, which is preset so as to provide an output pulse corresponding to a predetermined increment of motion during the paying out of the first layer. Additional counters are provided with different preset limits so that they will provide output pulses corresponding to the predetermined increment of motion during the paying out of second and additional layers of cable from the drum. As the cable is paid out or wound in, the output of the drum motion sensor is coupled to the appropriate pneumatic counter by means of a switching assembly.

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.

Each of the counter wheels and the metering value cams is arranged to represent a decade of a decimal system numerical value. Indexing pinions gear each of the counter wheels and the metering value cams with those representing a next adjacent decade.

Abstract: At least one presetting digit wheel consists of a rotatably mounted digit-carrying wheel part, a rotatably mounted resetting wheel part, and a non-positive two-way coupling means connecting the digit-carrying wheel part and the resetting wheel part for joint rotation. A rotatably mounted resetting shaft is provided. Lost-motion one-way coupling means are adapted to connect the rotatably mounted resetting shaft and the resetting wheel part for joint rotation only in one sense and only when the resetting shaft and said resetting wheel part are in a predetermined rotational position relative to each other. Detent means are adapted to hold the resetting shaft against rotation in a predetermined rotational position thereof, and locking key means are manually operable to hold the digit-carrying wheel against rotation when the resetting wheel part is rotated by said resetting shaft.

Abstract: A mechanical counting device for use in office machines such as copying machines in which almost all of the operative structure has been integrated into a single component. The surface works in conjunction with a ratchet pawl to count down from a preselected number, the number of completed cycles performed by the office machine. The counter energizes and de-energizes the office machine's operation at the start and finish respectively of this preselected number of cycles. In addition the counter includes a position for the continuous operation of the office machine without counting, and the capability to stop the operation of the office machine without disrupting the counting sequence.

Abstract: A preset counter has a case and one or more counter units. Each counter unit has a number wheel, a first intermediate wheel in mesh with the number wheel, a preset wheel and a second intermediate wheel in mesh with the preset wheel. Said first intermediate wheel comprises a first wheel which is in mesh with said number wheel and whose rotation is prevented releasably by a locking means and a second wheel which is disposed in opposed relationship with said second intermediate wheel, resiliently connected through a clutch to said first wheel and is formed with a recess or notch cut into the peripheral surface thereof. When the preset wheel is rotated, its movement is transmitted through said second intermediate wheel to said second wheel, but not to said first wheel. When the number wheel is rotated, its movement is transmitted through said first wheel to said second wheel, but not to said second intermediate wheel.

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.

The corresponding positions of said counter assemblies are adjustable to accommodate various limit positions of the associated device.

Abstract: This disclosure is directed to an attachment for a limited range gasoline pump. Many gasoline pumps are limited in price range to $9.99. The apparatus comprises an attachment wherein the number one is located on the face of the pump to extend its range to $19.99, and a flag bearing a dollar sign is placed over the number one. The flag remains in position if the sale is $9.99 or less. If that value is exceeded, the flag is moved to the left to expose the one, keeping the dollar sign correctly located. Movement is controlled by a cam attached to the rotating number wheel which displays the dollar value. This wheel is mounted on a cross shaft. The attachment cooperates with the cross shaft to respond to movement thereof to provide a reset motion when the gasoline pump is reset to zero.

Abstract: A counter device includes an outer annular dial which may be set to a desired detent position to indicate, for example, the number of copies required from a copying machine. A push button positioned at a null position within the annular dial may then be depressed to operate a control circuit initiating operation of the copying machine and simultaneously engage the counter mechanism of the counter device. The push button then moves incrementally to register with the setting on the annular dial, whereupon the counter device automatically terminates operation of the copying machine by opening the control circuit and simultaneously resets the push button to the null position.The internal mechanism of the counter device includes a ratchet and pawl operated by an external drive from the copying machine. The ratchet and pawl are advanced in incremental steps to register with the preset detent position of the annular dial. The ratchet is then released and returned to its initial or the null position.
