Title: Improvements in counting apparatus
IPC: G06M1/14
Filed: 1939-11-15
Abstract: 534,880. Transfer mechanism ; zeroizing mechanism. HASLER AKT.-GES. WERKE FUR TELEPHONIE UND PRAZISIONSMECHANIK. Nov. 15, 1939, No. 30126. Convention date, Dec. 17, 1938. [Class 106 (i)] Counting apparatus has number wheels rotatable upon a hollow cylinder having a longitudinal slot, the cylinder having therein a pawl carrier adapted to be rocked by a crank and a cam, the pawl carrier carrying a series of pawls having springs tending to thrust them outwards through the slot for engaging the wheels, each pawl except the pawl for the units wheel facing portions of the inner circumferences of two number wheels, and the inner circumferences being so toothed that before a pawl can engage the left-hand wheel which it is to drive, the right-hand wheel must reach a position wherein it releases the pawl for that purpose. As shown, a disc 1 fixed to one end of a hollow cylinder 2 having a wide longitudinal slot 3 carries an axle 4 on which is mounted a rotatable carrier 5 for the pawls 6, 7, 8 &c. The number wheels 9 are rotatable on the cylinder and are separated by anti-friction rings 10 restrained from rotation by noses engaging a groove 11. Each wheel 9 has on one side of the inner periphery ten notches 12, and on the other side a single notch in line with one of the notches 12. The pawl carrier 5 has two arms supporting an axle 14 on which the pawls 6, 7 and 8 are rotatably mounted, each pawl having a spring 15 tending to thrust it out of the slot 3. The ends of the pawls may be rounded or may carry small rollers 16. At one end of the carrier 5 is a crank pin 17 which projects through a slot in a cap 19 closing the other end of the cylinder and which engages a slot in a disc 22 carried by an eccentric pivot. The disc 22 has an aperture within which rotates a cam 23 fixed to a rotatable toothed wheel 23a. The width of the units pawl 6 is half the width of a wheel 9, and the other pawls of the same width as the wheels 9, so that each lies half within two adjacent wheels. When the wheel 23a is rotated, the pawl 7 engages the single notch at the tenth step of the units wheel 9, and rotates also the tens wheel to effect transfer. A similar transfer occurs in due course between the tens and the hundreds wheels, and so on. Each pawl 8 (the third and higher pawls) carries a lug projecting under the pawl on its right to prevent movement of the left-hand number wheel when it reaches the position 9 until the right-hand number wheel also reaches the position 9. The direction of rotation of the axle 4 is immaterial. For zeroizing each wheel 9 carries a stud 24 engaged by a spring 25 on backward rotation of the wheels 9 by turning the axle 4 by a screwdriver. The use of a key may be made necessary to prevent unauthorized operation. The disc 1 may have a notch 1<SP>1</SP> engaged by a spring loaded pawl 26 when zeroizing is completed.
