Abstract: 344,084. Typewriters &c. KRUPP AKT.-GES., F., Essen, Germany. Dec. 7, 1929, No. 37603. Convention date, Dec. 13, 1928. [Class 100 (iv).] Type-bar machines; hammer-impression arrangements; carriage-returning mechanism; columnprinting arrangements.-In a key-set independently operated cash register or like machine, a typewriter of usual construction is combined with the ordinary item-printing mechanism of the machine. The typewriter platen is common to both apparatus so that the slip thereon receives the imprint of credit and debt items and balances, as well as being printed upon by the typewriter. The invention is shown applied to an accounting-machine, described in Specifications 244,601 and 244,658, [both in Class 106 (i), Calculating &c.], having a set of slidably mounted rack-bars, Figs. 2, 3, geared to differential members 8 secured to the main shaft 7 and set by the amount keys. Two printing- mechanisms are set from the rack bars 21, one mechanism at the left-hand side of the machine for the record strip 24, Fig. 1, and the other mechanism at the right-hand side to co-operate with the paper carriage 22 of a typewriter 23. The amount is printed by type-wheels 28, Fig. 2, geared to the rack-bars 21. The account number is printed by type-wheels 27 adjusted, through gearing, by setting-levers 38, Figs. 1 and 2. The drive of the printing-mechanism is effected through a. drive shaft 46 geared to the main drive shaft 49. The consecutive number is printed by type-wheels 26 advanced in a similar manner to the consecutive number type-wheels of the slip-printing mechanism. Vertically slidable type carriers 50, Fig. 3a, for slip-printing have movably mounted individual types and are arranged on the right of the typewriter, the nine carriers 54, Fig. 2, on the left, for the amount, being adjusted through gearing by the rack bars 21. The next five carriers 55, Fig. 2, for the account number are adjusted by the aforementioned setting-levers 38 through gearing and telescoped tubes 37, Fig. 1. The remaining three carriers 56, Fig. 2, for the date are adjusted by hand. Type-wheels 57, Figs. 2 and 3, for the consecutive number are carried by an arm 75 mounted to swing upon a drive shaft 74 geared to the main shaft 49. Between the shaft 74 and the units wheel of the type-wheels 57 is a geneva wheel -drive consisting of a disc 83, fixed to the shaft 74, having a driving pocket 82 which, at each revolution of the disc 83 engages a spur wheel 84 geared to the units wheel. The type-wheels 26 for the record strip are advanced in a similar manner by the shaft 46. The type-wheels 57 and pivoted hammers 86, Fig. 3a, for co-operating with the type carrier 50, are held back, against the action of springs 87, 95, by a frame 92 journalled on a shaft 91 and rocked when the machine is operated by a cam disc 97 to permit the hammers 86 and type-wheels 57 to execute a printing motion, under the action of the springs 87, 95, upon the slip in the paper carriage 22. To permit the type-carriers 54 to print independently of the carriers 55, 56 and the typewheels 57, the hammers 86 of the carriers 55, 56 and the arm 75 are further held back, against the action of the springs 87, 95, by a frame 105 journalled on a shaft 104 and connected to a shiftable rod 107 engaging the lower end of a locking rod 109, Fig. 3, which is only raised to render the frame 105 inoperative when setting up the old balance. The rod 109 is raised by the action of pins 111 on the old balance keys 3 engaging inclined surfaces 112 on a key slide 110 attached to the rod. The slip on the paper carriage 22 is in the form shown in Fig. 15, the columns 113 being printed in the normal way by the typewriter, the paper carriage being moved to' the left by a cord 301 upon a spring drum 300, Fig. 2, under the control of the usual escape mechanism operated by the type-bars of the typewriter. The remaining columns 114 .. 117 are printed by the machine, the first operation printing columns 114 for the old balance account number, date, and consecutive number, the second operation printing the debit column 115 or the credit column 116 and the last operation printing the new balance column 117. To bring the necessary column on the slip opposite the type-carriers 54, which necessitates a one or two column movement of the carriage to the right, a rack-bar 121, Fig. 6, connected to the carriage frame 119 is geared, through wheels 122, 124, to a rotatable shaft 123 carrying a toothed member 125 gearing with driving-discs 135, 136 and teeth 145 on a shaft 134 geared to the main drive shaft 49. The member 125 is slidable on the shaft 123 so that one set of teeth 131 thereon can be selectively engaged with either driving- disc, 135, 136 one disc having one driving-pocket, and the other, two such pockets, so that the position of the sliding member 125 determines the column movement of the carriage. The member 125 is adjusted by a forked member 147, Fig. 7, having a roller 151 engaging a cam slot 150 in a drum 152 fixed to a rotatable shaft 148 and connected to a thrust rod 154, Fig. 8, having a detachable connection with a driving-arm 158 which is given a to-and-fro swinging motion at each operation of the machine. The thrust rod 154 is supported by a link 155, Fig. 3, connected to a key slide 159 having inclined surfaces 160, 170 which are engaged by pins 111 on the credit and new balance keys 3, when either is depressed, to raise the link 155 and disengage the thrust rod 154 from the driving-arm 158. When the carriage is moved back into its right-hand position at the end of the last operation of the machine, a bell-crank lever 161, Figs. 3 and 3a, carrying a pawl 162 engaging ratchet-teeth 167 on the platen, arrives under a lever 164, rocked by a shaft 49, to advance the platen one line. To prevent the type-carriers and wheels 54 .. 57 printing when the papercarriage is raised to its capital letter position and to prevent the paper-carriage being raised to the capital letter position during an operation of the machine, a locking-rod 176, Fig. 4, is moved, through linkage, by a key slide 171 to engage over the carriage when either of the top two motor keys 4 are depressed. When the carriage is raised, the locking-rod abuts against the rear face of the carriage so that the keys 4 cannot be depressed. To permit the machine to print only when the paper-carriage is correctly positioned and to prevent lateral movement during printing, a lever 181 is engaged with notches 191, Fig. 2, in a flange 179 in the rack-bar 121 when either of the top two motor keys 4 are depressed to operate a key slide 187 to which the lever 181 is connected by linkage. To prevent release of the machine before the columns 113 have been printed by the typewriter, the key slide 187 is connected by linkage to a pawl 192, Fig. 4, which co-operates with a projection 193 on a lever 195 which is engaged by lugs on the flange 179 to swing the projection 193 clear of the pawl so as to allow the key slide 187 to move when the carriage reaches its left-hand position after the printing of columns 113. To hold the paper-carriage in its starting position during the operation of taking a total from a selected totalizer a locking finger 205, Fig. 9, is moved into a notch 209 in a disc 204, rigidly connected to the toothed wheel 124, by a sliding bar 215 connected to a lever 5, Fig. 1. To release the keys 4, which are locked in the lever 195 when the carriage is in starting position, for the purpose of total taking, the lever 5 is positively connected to a cam disc 210, Fig. 4, which moves down the key slide 187 so that the keys can be depressed irrespective of the locking position of the lever 195. To ensure that every total-taking operation is preceded by a clearing operation, the lever 5 can only be moved from its position of rest after a clearing operation. To ensure that the lowermost key 4, for clearing operations, can only be depressed when the carriage is in its starting position, this key operates a key slide 219, Fig. 4, connected to a lever 222 which engages under the flange 179 permits the keys to be depressed only when a notch 223, Fig. 2, in the flange 179 is above its free end.
