Abstract: 258,902. Strichow, K. Sept. 28, 1925, [Convention date]. Moving - chamber apparatus with printing and recording apparatus. - A measuring and recording device for liquids is designed so that the volume of liquid to be measured is predetermined by the adjustment of a pointer. Preferably this pointer and its indicating-dial, or, if the apparatus is coinfreed, an operating-handle and a slot are the only accessible parts of the apparatus. The device comprises a compartmented rotating drum 4, Fig. 9, set inside a casing 1, Fig. 2, including also a platen printing-device 38, an indicating-dial 31 and pointer 32 set by a knob 33, and a counter 79. The indicating-pointer is set by hand to predetermine the number of discharges of a unit of liquid to be effected, i.e. of the volume of one measuring chamber, and the parts are subsequently rotated by the incoming liquid. The printing-device 38 prints and cuts off from a roller 44 a ticket bearing the date, the quantity sold, and other particulars. The coin-freed apparatus comprises a lever 85, Fig. 11, which is locked to an operating spindle by an inserted coin. The pointer 32, Fig. 2, is rotated clockwise over the dial 31; on its spindle 29 is a gear-wheel 30, Fig. 6, which rotates, through another gear 28 a cam 23, which moves the lever 20, Fig. 5, and opens the control valve 14. Simultaneously levers 58, 60, Fig. 3, bring the printing " pressure " plate 38 into position, and a lever 68 moves laterally a rack 69, which rotates the feeding-roller 45 for feeding forwards the paper, web 44. Further, a pawl 70, acting on the ratchet 51, feeds forward a printing-ribbon 48. When the pointer 32 in the manual-adjusting movement arrives at the end of the heavy black mark shown on the dial 31, Fig. 2, the lever 68 slides off the rack 69, which is retracted by a spring 71, without moving the feeding-rollers 45, 50. The pointer 32 continues to be moved manually clockwise until it reaches the number indicating the quantity of liquid desired to be delivered. The liquid is now passing through the valve 14 and pipe 15 to the central chamber 5, Fig. 9, of the drum 4, and thence, through a perforation 9, into the outer chamber 6, 7, or 8 which is below the chamber 5. As the filling proceeds, the drum becomes unbalanced, and gradually rotates, and the filled chamber 7 is emptied through a channel 10, falling into the casing 1, and away through a hose &c. As the drum rotates, it actuates wheels 53, 78, 73, Figs. 5 and 6, by means of pins 80; the wheel 73 moves the cam 23 and the shaft 29, so that the pointer 32 will rotate clockwise over the dial 31; the wheel 53 actuates the type wheel 35, Fig. 3, and the wheel 78 actuates the counter 79. When the pointer 32 reaches the zero on the dial, the cam 23 releases the lever 20; the valve 14 then shuts off the supply of liquid, and the lever actuates the printing-mechanism, the pressure plate 38 being moved upwards against the type wheel 38 and the date &c. wheel 37, so as to print a ticket which is cut off by a knife 43. After this operation, a locking-pawl is lifted, and the parts resume their zero position. As the lever 20 is being released, a. pawl 26 on it engages with one of the pins on the drum 4, and rotates it just as the valve 14 closes. A coin freed modification comprises a slot 87, Fig. 11, down which a coin falls to enter one of a number of slots in a disc 84 on the spindle 29, and to engage with a handle 85 by means of which the spindle 29 may be rotated to a fixed extent, there being no choice of quantity delivered.
