Abstract: 910,535. Counting-apparatus; zeroizing-mechanisms. KIENZLE APPARATE G.m.b.H. Feb. 22, 1960 [Feb. 21, 1959; Oct. 2, 1959], No. 6128/60. Class 106 (1). [Also in Group XXIV] In liquid dispensing apparatus having a presettable counter and adapted to deliver preset quantities of liquid, a quantity counter and a printing quantity counter are zeroized by a single zeroizing member which is also arranged to reset the presettable counter. General arrangement.-As described, the register of a liquid delivery pump comprises a printing unit 1, a quantity counter 2 zeroized after each delivery, a totalizing counter 35 (not reset) and a presettable counter 37. A voucher is printed for each delivery, wheels 28 printing the delivered quantity, wheels 29 printing a pump designation and wheels 30 printing serial numbers for the successive deliveries. The counters 28, 32, 35 and 37 are driven by gearing from a shaft 42, Fig. 2a, which is driven in correspondence with the liquid delivered. The quantity counter 32 and printing counter 28 are driven through ball detent clutches 45 and 59 (see Group XXIV) which are disengaged during zeroizing, and the presettable counter 37 is driven through a further ball detent clutch 55 which is disengaged after the predetermined quantity has been delivered. Zeroizing control.-The counter shafts 27, 33 and 36, Fig. 1, are connected by gearing 82-86, and zeroizing of the three corresponding counters is effected by rotating manually a handle 81, normally in a position I (not shown) clockwise through 410 degrees to a position II (not shown) and then counterclockwise through 50 degrees back to the position I. The handle 81 is coupled to the shaft 33, on which is fixed a slotted disc 88, Fig. 8, clockwise movement of which causes a disc 91 having a pin 90 engaging in a slot 89 of the disc 88 to rotate initially thereby causing a second pin 103 on the disc 91 to rock a lever 93 fixed to a shaft 104. The shaft 104 carries levers (not shown) which disengage the clutches 45, 59, Fig. 2a. When the handle 81 has rotated through 410 degrees to the position II, the pin 90 re-engages the slot 89 and a third pin 92 on the disc 91 engages a notch 95 on the lever 93, the arrangement of Fig. 8 being regained with the final counter-clockwise rotation of the handle 81 back to the position I. The motion of the handle 81 is transmitted to the shaft 36 of the presettable counter 37, pick-up pawls 105, Fig. 14a, on the numeral wheels thereof co-operating with a groove in the shaft 36 to zeroize the numeral wheels. Presettable counter.-Each numeral wheel of the presettable counter 37 consists of two internally toothed parts 106, 107, Fig. 13, the part 107 carrying a driving gear 108 and the part 106 carrying a transfer tooth 120. When the shaft 36 is rotated for zeroizing, the part 107 is driven via a zeroizing pawl 105, and the part 106 is driven through a lever 116 which cooperates with a pin 115 mounted on a lever 111<SP>1</SP> on the part 107, the lever 111<SP>1</SP> co-operating with internal toothing 109 on the part 106. When the zero position is reached at the end of the clockwise rotation of the handle 81, a zero stop pawl 118 holds the part 107 stationary, and the part 106 is stepped to the required digit by repeated manual depression of a button 129 which controls a stepping pawl 127 co-operating with pins 126 on the part 106. When the handle 81 is returned back to the position I, the pawl 111<SP>1</SP> is again locked and the zero stop pawl 118 is swung away from engagement with the wheel part 107. Means are provided (Fig. 12, not shown) for preventing actuation of the buttons 129 during a delivery operation. Each numeral wheel has a collar 121 on which rests a roller 124 on a lever 123, all the levers 123 being parallel and keyed to a shaft 130 which also carries a stepped lever 135, Fig. 10. After adjusting the counter 37 to the required value, a manual lever (not shown) is operated to rotate a shaft 136 and lever 137 clockwise, thereby opening a liquid delivery valve (not shown), a rod 140 on the lever 137 moving to the left to bear on the first step of the lever 135. During delivery the counter 37 counts down, the wheels successively reaching zero, at which position the rollers 124 are opposite notches in the collars 121. The units wheel has a stepped collar 121 so that after all the higher wheels have reached zero, the lever 135 is progressively moved upwards to effect a gradual closing of the delivery valve. When all the wheels have reached zero the clutch 55 is disengaged. Delivery may be stopped manually, if required, by depression of press buttons 206, 207, Fig. 1, connected to pawls 203, Fig. 10, connected to the lever 135. Means comprising a slotted disc mounted on the shaft 36 are provided to prevent delivery during zeroizing and vice versa (Fig. 9, not shown). Printing-counter, Fig. 15.-The printing-counter is driven during delivery through a flexible coupling 172 which transmits the drive to the lowest order wheel. The shaft 27 of the counter is rotated for zeroizing by the handle 81, but means are provided for obtaining a rotation of 365 degrees forwards and 5 degrees backwards. The higher order wheels are justified for printing by springs 179 which are rocked into engagement with the transfer pinions 180 of the counter. A pinion 174, rotated during zeroizing, drives a gear 181 on a shaft 182, a snail cam 183 also on the shaft 181 being driven through a lost motion connection from the gear 181, the cam 183 being rotated through 360 degrees only during the zeroizing operation. At the commencement of zeroizing a roller 188<SP>1</SP> drops from the high part of the cam 183 to rock a lever 188 mounted on a shaft 189 carrying printing-levers 190 which then effect the printing operation. A lever 183<SP>1</SP> on the shaft 182 is arranged to move a linkage 194, 195, 197 to cause a lever 170 to move to the left so that a projection 171 thereon justifies the lowest counter wheel before printing takes place.
