PRINTING OB TYPING. ADDING OR SUBTB-ACTING MACHINE OR TYPING CALFULATDJ'G MACHINE Application filed February 5, 1929, Serial No. 387,685, and in Austria February 7, 1928.

This invention relates to improvements in typing calculating machines with printing mechanism, a transversely moving paper carriage and a number of counters which are movable in accordance with or independently from the paper carriage.

The essential feature of the' present invention consists in this that the movable counters as well as the actuating mechanism therefore form a unit which is quite separate from the machine but can be fitted to any existing calculating machine. All that is necessary is to couple or connect the actuating mechanism of the unit with the actuating mechanism of the I said calculating machine with printing mechanism.

The counters which may be of various sizes (capacity) are arranged preferably readily removable at desired distances apart on the paper-carriage.

One mode of carrying out the present invention is illustrated by waj of example on the accompanying sheets of drawings in which Fig. 1 is a side view of the arrangement.

Fig. 2 illustrates a similar view of differ ent parts of the machine.

Fig. '3 is a rear view of the paper carriage with the counters, and so a Fig. 4 is a perspective view of a portion of thelmechanism shown in Fig. 2 to an enlarged sca e.

Fig. 5 is a perspective view of a detail and Figs. 6, 7, 8 and 9 illustrate the control mechanism in four diflferent positions.

Fig. 10 is a perspective general view of the machine according to the present invention. The parts in Fig. lillustrated by the thinlines show the known construction of the typing calculating machine, which essentially is provided with type-holders or bars 1 (covering each other in the drawings), the stroke or movement of the same being limited in known manner by adjustable members 2, which are operated by keys (not illustrated). When lifting the type-holders or bars by means of the double armed lever 3, operated by a hand-crank, and the pivoted connecting rod'4, the raised position of the former depends on the operative position taken up by the adjustable members 2 according to the number set at the time. The types of the individual type-holders or bars are disposed in a line, so that the set number can be printed on the paper, passing over the platen-roller 5.

Before the return movement of the typeholders or bars the toothed segments 6, which are connected with the levers 3, are placed in mesh with the wheels of the counter 8 by rocking the arms 7 in known manner, so that each counter-wheel takes up the return movement of the corresponding type-holder.

The further arrangement according to the present invention is illustrated in thick lines in Fig. 1.

A U-shaped bar 12 is pivotally secured by means of arms 11 to the side faces of a slide 10, which carries the paper-roller 5. The column-counters 13 are arranged longitudinally movable on the said bar (Figs. 1 and 3). Clamping members 16 are secured to the lateral parts 15 of the casings of the counters 13 by means of screws 16 and together with the lateral parts 15 embrace the flange 12 of the bar 12. The casings with the counters can be shifted when the screws 16 are loosened, while the same are fixed by tightening thelatter. The object thereof is to permit the suitable adjustment or setting of the individual counters for the columnarrangement. The individual counters 13 are successively operated by the type-holders or bars 1 by the feed of the slide 10, the number of counters 13 mounted on the bar 12 corresponding to the number of columns to which the machine is adapted". For this object each type-bar 1 is provided with a dpin 1 each of which engages the forked en of a lever 17, the other forked end of the latter engaging a pin 18 of aspringy rocking member 19, which engages a longitudinally movable rack 20. The movement of the rocking member 19 brings it into engagement with a stop 20 mounted on the rack, so that the latter is. shifted after the rocking member engages the stop. The principal object of the idle motion of the member 19 is to move the type-bar 1 into the printing position of the figure nought by depressing the noughtkc without influencing the rack 20 and thus an sequent-1y the corresponding wheel of the counter 13. The idle movement of the lever 19 also serves for rendering possible the tenstransmission.

Further during this idle movement various other adjusting movements are carried out in the machine as will be described at a later stage. The lever 19' comes against the stop 20 just at the moment when the noughttype is disposed in the printing position. From this .moment the rack 20 is moved downward, while the lever 19 is continuously pressed onto the stop 20 by the spring 19 The printing operation and at the same time the return movement of all tens-transmission arresting p awls, 22 bythe returnrail 25, as will be described later on, is carried out whenever the type-bars 1 have taken up their highest position corresponding to the set amounts.

. The return movement of the lever 3 and thus of thetoothed segments 6 and of the type-bars 1 commences after the engagement of the counters Sand 13. The toothed segment 6 rotates the figure-disks of the counter 8 to an extent, corresponding to the number of teeth through which the segment has moved. The tens-transmission is constructed in the followingmanner, in order to dispense with the arrangement of a separate tenstransmission for each column-counter:

Each rack 20 is provided with'a springloaded hooked lever 21, which holds down a x spring-loaded flap-lever, 22 for limiting the can return into its initial position and thereby rotate the counter-wheel to anextent corresponding to the number set in the machine. Each counter-wheel is provided with a tenstooth 23, which during the movement past arm 24 of the hooked lever 21 turns the latter,

I whereby the lever 22, limiting the stroke of with or disengaged from the racks 20 in a certain order, according to the desired operation ofthe machine, for example, entering an item in the counter, indication of an intermediate sum or subtotal in the counter 8, and printing of the total. During the usual calculation, e. g. the registration and printing of the amounts with subsequent advance of the carriage, the counters 13 have to be engaged only at the same time as the counter. 8. The engagement and disengagement of the counters is substantially carried out during the idle stroke of the type-bars 1 from the basic position to the zero-position. However if it is desired to take a total from the column-counters, it is necessary that the corresponding counter 13 shall be in the engaged position during the upward stroke of the type bars 1 and disengaged during the return movement. indicated in the counter 8 by turning back the wheels of the counter 13 to such an extent by means of lifting the type-bars, until the tens-transmission teeth 23 strike against the arms 24 from the opposite direction and, because the teeth do not find inclined faces at. this side, each counter-wheel is arrested in the zero-position, whereby the lift of-the type-bars 1 is limited. The latter are now disposed in the position, which corresponds to the values standing in the counter 13. The column-counter is now in the zero condition and ready for a new registration.

Therefore the counters 13 have to be engaged in three different ways, namely either only during the return movement of the typebars or only during their lift and finally for a sub-total during the lift and return movement of the same. The arrangement shown in Fig. 2 is suited for carrying out the said three difi'ere'nt operations. The U-shaped bar 12, already shown in Fig. 1 and pivotally secured to the, slide of the paper-roller-by means of the levers 11 and carrying the casings 15 of the column-counters on the bar 12, is provided with a lateral bar 26 which is engaged by rollers 27 and 27 The latter are mounted on one arm of a lever 28 furrecesses of a control-disk 30, so that the lever 28 is turned according to the position of the control-disk and thereby the bar 12 is displaced and consequently the counters 13 (Fig. 1) arrangedon thesame are moved into or out of engagement with the racks 20 (Fig. 1). The control-disk is rotatably mounted on a pin 31 secured to the frame, and is operated as follows. A lever 32, provided with three arms, is mounted on the pin 31 and one arm of the former is connected by a connecting rod 33 with the hand operated crank or other driving means for operating the machine, so that the said arm moves to and fro through an arc of ninety degrees when operating the said crank. The second arm of the lever 32 carries two pawls 34, 35, the pawl 34 rotating the disc clockwise and the pawl 35 anticlockwise. Therefore, dur ing the operation of the lever-arm, the control disk 30 is turned in one of the two direc: tions of rotation. The following arrange- The sum is printed or nished with three arms, each of the two other ment serves for controlling the pawls 34 and 35 On the in 31 are mounted two cranked levers 36, 3 which can be adjusted in different positions to each other and are provided with pawls 38, 39 extending into the path of movement of the pawls 34, 35.

The pawl 38 operates the pawl 34 during the forward movement and the pawl 39 cooperates with the pawl 35 during the return movement. v

The other arms of the levers 36, 37 are provided with stops 36 37 which engage .recesses of control segments 40, 41.

The control segments are adjusted b the keys 42, 43 through the intermediary 0 link rods 41, 40 so that the levers 36, 37 come to rest either in position I or II. For limiting the movements of the levers 36, 37, spring pawls 44, 45 are provided, the noses of which engage in recesses 46, 46 on the levers 36, 37 and, during the displacement of the levers 36, 37 are first of all lifted by the control segments. For this purpose each of the pawls 44, 45 has lateral pin 50 which engages in a guide of the control segments.

When one of the keys 42 or 43 is actuated, the corresponding control segment 40 or 41 is actuated and, by means of its guide which controls the pin 50, first of allpulls the nose of'the pawl out of engagement with the recess 46, whereu on the lever 36 or 37 is released and can e rocked by the control segment. In the other extreme position of the lever 36 or 37 the pawl 44 or 45 again snaps into the recess 46 and holds the lever securely in position. As already mentioned, the column-counters 13, which in their inoperative position are out of engagement with the actuating members 20, are only moved into engagement therewith, when an item is being entered, during the downward movement of the type bars 1 or the upward movement of the actuating members 20.

Figure 2 shows the position I of the cranked levers 36, 37 of the controlling mechanism, in which the column-counters are being actuated for the entering of an item.

During this cycle of operations, the pawl 34 is lifted from the lower recess of the control disc 30 by the pawl 38, which is situated in the initial position I, immediatel yat the beginning of the controlling movement of the three-armed lever 32 actuated by the connecting rod 33. During the further rotation of the lever 32 the pawls 34, 35 are. moved idly along with. it until they drop into the upper recess of the control disc 30 and then rotate this disc during the remainder of the rotary movement of the lever 32 clockwise. By this -means the three-armed lever 28 carrying the rollers 27, 27 will have been rotated and the movable column-counters 13 swung into engagement with the teeth of the actuating members 20 which are already situated in their lower end position (Figure 6). During the subsequent return movement of the crank, the pawl 35 will be lifted immediately from the upper recess of the control disc 30 by the pawl 39 of the cranked lever 37 situated in the initial osition I, so that the columncounters 13 in question remain constantly in engagement with the actuating members 20 durin the upward movement thereof. Atthe end 0 the return movement of the crank, the pawls 34, 35, which during the upward movement of the actuating members 20 have been slid over the periphery of the control disc 30 by the lever 32, drop into the lower recess of the control disc under the action of their springs and rotate this disc in the anticlockwise direction into its initial position in which the counters 13 are again out of enga ement)with the actuating members 20 (Figure 2 6 However, before the type bars 1 .have reached their highest position or the actuating members 20 their lowest position, the tens flap levers 22 are returned by the return rail 25 (Figure 2).

For this purpose the three-armed lever 32 carries on its third free arm a connecting rod 49 which, by means of a longitudinal slot provided in the latter engages a pin on the return rail 25 and pulls the latter down only during the latter portion of the rotation of the lever 32 in the clockwise direction and thereby causes all the flap levers 22 which have been disengaged to come again into engagement (Fig. 6).

During of the rack bars 20 the flap levers 22 are already in their initial position ready to perform a fresh tens transfer operation.

If a figure which is not to be added (for instance a number or date) is to be printed, then the counters 13, as above mentioned,must

remain out of all engagement with the rack bars 20 during the upward movement as well as the return movement of the type bars 1. For this purpose, before connecting up the driving mechanism of the machine, the key 42 .is actuated which moves the cranked lever 37 through the medium of the control segment 41 into the position II (Figure 4).

During the movement of the three-armed lever 32 in the clockwise direction, the pawl 34, as above described, is lifted out of the lower recess of the control disc 30 and without influencing the latter is caused to slide over the periphery thereof until it again falls into the upper recess and carries the control disc round with it during the remainder of the rotary movement of the lever 32. The counters 13 moved into engagement in this manner with the rack bars 20, however, at the beginning of the return rotation of the lever 32, during which the controldisc 30 is returned by means of the pawl 35 engagthe following upward movement By this means the column counters 13 in question are not in engagement with the rack bars either during the downward movement or the upward movement of the rack bars.

Therefore the calculation mechanism is dis- 4 engaged and this position is utilized for typing the numbers.

If the sub-total key 43 is depressed, the control segment and thus also the lever '36 will be turned, so that the pawl 38 does not interfere with the start of the movement of the pawl 34 carried by the lever 32, so that during this movement the said pawl remains inthe corresponding notch or recess of the control-disk and takes along the same, im-' mediately at the beginning of the working stroke, so that the column-counters 13 are moved into the operative position before the racks 20 are operated (Fig. 9). In the outermost position of the lever 32, the pawl 35 engages the notch 'of the control-disk 30, but is again disengaged (lifted off) during the start of the return movement by the pawl 39, so that'the control-disk remains in the position in which .the counters 13 engage the racks 20. Just before reaching the initial position, the pawl 35 cooperates with the end'of the other notch of the control-disk and turns the same to such an extent, that these counters 13 are disengaged.

This position serves for forming intermediate sums, that is, sub-totals. In view of the fact that the counter-wheels, when forming the intermediate sum, engage the racks 20 during the to and fro movement, all counter-wheels are at first adjusted to zero-position, whereby the sum set in the same is printed by the type-bars 1 and also is entered in the counter 8, and subsequently the said counter-wheels are returned again to the amounts contained therein, so that further set amounts may be added thereto.

If it is desired to form column-totals, the keys 42 and 43 are depressed and thereb the control- segments 40 and 41 are adjusts and thus the levers 36 and 37 with the pawls 38 and 39 are turned in opposite directions to one another. Therefore the pawl 38 permits the rotation of the pawl 34 to some extent,

'4 Leeann The simultaneous de ression of the keys 42 and 43 can be carrie out by a separate key 48 (total key), which is. provided with a transverse bar and'cooperates with the levers of both keys 42 and 43.

I claim 1. In a typing'calculating machine withf printing mechanism, a transversely moving paper carriage, anumber of movable counters and actuat1ng members therefor, said countersas well as the actuating members being fitted to the outside of the machine behind and below the fixed counters and typing mechanism, a control-disk moving the -movable counters into and out of engagement, a pawl-lever operating said controldisk, pawls on said pawl-lever and engaging notches of said control-disk.
