Abstract: 615,304. Cash registers. SOC. ANON. OFFICINE DI VILLAR PEROSA. Nov. 29, 1940, No. 17065. Convention date, Oct. 16, 1939. [Class 106 (i)] A differentially set and independently hand-operated cash register has setting levers, each formed with two sets of teeth to set customer's and operator's item indicators at the front and rear respectively and spring linked to a co-axial toothed sector which operates a totalizer which is rocked into gear therewith by a cam driven by the main shaft. Loosely. mounted on the main shaft 1 are toothed sectors 3 and toothed circular portions 21 of the setting levers, a spring 8 between each sector and setting lever causing an edge 3<1> to bear against a stop tooth 9 on the setting lever. Rotation of crank 7 causes rotation of a shaft 18 and a cam 17, Fig. 7, causes lowering of arms 10 carrying the totalizer which then meshes with the teeth d of the sectors 3. Teeth d<1> of the setting levers engage pinions 22 to set customer's item indicators, while teeth d<11> engage pinions 23 to set operator's indicators which are keyed on concentric tubular shafts 25, each carrying a printing disk 24. After the totalizer has engaged the sectors 3, a cam 32 actuates a lever 33, a toothed sector 35 of which moves a toothed sector 36 of one of two arms 5 so that a bar 6 connected between the arms 5 restores the sectors 3 and transmits readings to the totalizer. A roller 27 is urged by a spring 29 against teeth 26 on each setting lever. If the arm 2 of a setting lever is not moved to its correct position, the roller remains on the apex of a tooth and a bar 37 is moved, thus turning a shaft 30 so that a lever 39 on its end engages a lever 41 and carries a tooth 44, Fig. 6, into engagement with a pinion 19, locking the crank 7. A cam 49 causes a tooth 50 to engage the pinion 23 when the crank begins to rotate, thus locking the setting levers against the action of the springs 8 at the beginning of the operating cycle. The crank is stopped at the end of a cycle by engagement of a tooth 55 on pinion 19 with one end of a lever 51, Fig. 6, which is swung into the path of the tooth by a pin 53. On taking one's hand off the crank the spring 54 releases the lever from the tooth. The last setting lever 21, Fig. 9, is used to set 5 cents in conjunction with any of the operations, a tooth da on its sector 3a striking the teeth of the pinion T. A lever 56 pivoted at 57 is moved by a pin 60 on the sector so that a tooth 58 engages the pinion T and prevents it moving more than one tooth. Setting the type of operation.-The first setting lever 2a has two sets of teeth only and no corresponding sector 3, one set of teeth 261 having twice the pitch of teeth 26 on the other levers and setting the type of operation to be performed, viz. " cash," " partial payment," " on credit," " withdrawal ". The corresponding pinion 23 shows a corresponding indication at the front and also actuates a printing disc. A lug 55 on the lever 2a strikes lever 12 in moving to the " on credit " or " withdrawal " position, thus disengaging lever 12 from pin 13 so that the totalizer is not brought into action. Ticket issuing and printing.-In the " on credit " and " withdrawal " operations a spring m holds a tooth 64 in a recess 62<1> thus keying a wheel 63 to a. shaft 62 and transmitting to the shaft through wheels 63, 63<1>, the action of the camshaft 18 so that a ticket is delivered. But when the lever 2a is moved to another position a pin 67 on it engages the foot 66a of lever 66 and moves it against the pawl 64a, releasing the tooth 64 and preventing automatic delivery of a ticket. The ticket roll is mounted on a roller 68 and is passed between a pressure cylinder 70 and a printing cylinder 69 which has a section of smaller diameter that is in front of the pressure roller in the inoperative position so that a new roll can easily be inserted. Total-taking.-A lock 61 with two keys is provided, Fig. 15. By turning this lock a roller 79 pivots a lever 81 against the action of a spring 83, a knob 84 of which engages the pinion 19. At the same time a step on sector 75 moves a lever 85 which causes a lid to be lifted, Fig. 19, not shown, to disclose the totalizer reading. If, however, the second (and longer) key is used, the sector 75 rotates further to bring an opening 78 in front of another lock 87, into which a further key is inserted to zeroize the totalizer. Indicators.-A drum (Fig. 12, not shown) is divided into coloured sectors visible through an opening 901 and a second opening in the side of the casing and is connected to the cam-shaft 18 in such. a way that a change of colour takes place for each full cycle.
