April 27, 1938 19 Claims. (01. 101-413) cash registers, bookkeeping machines, or similar machines, of the type employing a record sheet,
such as an account card, which is introduced sideways mto the machine, that is, transversely to the direction of line shift. The object of the invention is to improve the mechanism for bringing a record sheet which has been introduced, to the right line for printing, and for shifting the record sheet to a new line after each printing operation.
French Patent No. 824.525 is an example of ,a machine of'the class described, utilizing a record sheet which is introduced sideways-into the machine. According to this patent the record sheets are set directly by hand to the corresponding line to be printed. Thesetting of the record sheets of other known'machines is accomplished indirectly by the machine operation, after a suitable setting means has first been operated. According to the number of bookkeeping operations the record sheets are left in the machine for a shorter or longer time and after being printed upon by the machine are removed. Upon further use the record sheets must again be inserted in the machine and, either by hand, or by the machine operation after previous setting of a setting device, set' to the proper line-to be printed upon.
The present invention has for itsobject to eliminate the constant setting of the various record sheets to the line to be printed upon, either by hand, or by a machine operation following the According to the invention thevarious record sheets which are inserted into the machine for carrying out one or more bookkeeping operations exert their own control upon a mechanism which sets them auto- -matically to the right line.
' The application of this idea to record sheets which are to receive a plurality of difierent lines 'of printing leads to the advantageous result, that the record sheet, which is .always inserted at the same place, is not only automatically moved to the line to be printed upon, but is also advanced directly from thelast line printed upon to Figs. 2 and 2a are two parts of. a vertical sectional view of the same mechanism, taken from the bottom of Fig. 1;
Fig. 3 is a vertical section taken from the left of Fig. 1;
Figs. 4-8 are detail diagrammatic views illustrating various positions of the feeler and locking devices of the record sheet adjusting mechanism, the feeler devices appearing in plan view and the locking devices in side elevation;

'The-inventionwill be described with reference to one illustrative example shown in the accoming drawings, wherein Figs. 1 and 1a show two parts a plan view of a printing mechanism in accordance with the invention, with portions broken away and other portions in section;
printing table; and
Fig. 14 is a face view of a part of the table control mechanism A printing table ass (Figs. 1, 1a, 2, 2a, and 3) guided upon rollers 96411 is provided with corner pockets 919 for holding an account card 91! inserted into the machine from the left (Fig. l). The inwardly presented edge 912, 913, (Fig. 1a) of the account card coacts with feelers 914, 915, which are rotatably mounted by pins 911 (Fig. 2a) upon levers 916. These feelers serve, in a manner to be described, to control a mechanism which acts immediately upon insertion of a card to move the table in either direction to bring the proper line of the card toprinting position, unless the table happens to be in the right position when the card is inserted. The ends 918 of feelers 914,. 915, are guided in holes 919 of the machine frame. To the levers 918- are connected links 989, 98!, (Figs. 1-3,) whose other ends are connected at 982 to locking dogs 983, 984. The looking dogs 983, 984, are rockably mounted upon a shaft 985 and are drawn by tension springs 988. The dogs 983, 984, have ledges 983a and 988a,
respectively, which coact with .tops 999a and 9890., respectively; of locking disks 999, 989 (Fig.
' other. The crown gear wheels 9!", 992, areremachine operation. The crank disk I021 is se- 'shaft 904.
upon pins 999a and 1000a. fixed by hubs 999D and I000b respectively to shafts 991 and 990.
Two gear wheels I040 and I039 are fixed by pins to shafts 991 and 995 respectively and both mesh with a. gear I031 fixed to a shaft I038. Also fixed to shaft I030 is a pinion I035 meshing with a rack bar I033, which is attached by bars I035 and W351: to the printing table 959. nism serves to drive the printing table in either direction required to place the card in correct printing position, as will be described presently.
The gear ratio is such that the table will move from one line to the next as the locking disk 989 5 or 990 makes one complete revolution, or a whole number of revolutions.
The spur gear 995 is connected to a spur gear 1001 (Figs. 1 and 3) through'a chain of gears consisting of the gear wheels IO0I, I002, which are fixed to a shaft I005, and gear wheels I003, I004, which are rotatably mounted upon a shaft The spur gear I001 has pivoted to it a of a ratchet wheel IN I, which is fixed to a spring barrel IOI2. The spring barrel I 0I2 carries a spring IOI3, one end'of which is fastened to the barrel IOI2, while the other end I0 is clamped to a stationary post IM 5. is rotatably mounted upon shaft I009. The spring I M 3 tends to rotate the locking disk 990 (Fig. 3) in clockwise direction, acting through the pawl coupling I009, IOI0, I0, and the gear wheels I001, I004, I003, I002, MM, 996, 994, I000, 992;
and tends to rotate the locking disk 909 counterclockwise, acting through the wheels I001, I004, I003, I002, I0, 995, 995, 993, 999, 99I. This rotation of the locking disks is normally prevented by the ledges 983a, am, of the dogs ass,
984, which release the locking disks alternatively, to allow the table to be moved in one direction or the other.
The spring I 0 I3 is rewound each machine operation, by the following mechanism: Fixed to the spring barrel IOI2 is a spur gear IOI5 (Fig. 3). This spur gear meshes with a toothed wheel M, which is freely revoluble on shaft I005. The shaft I 006 has fixed on it a toothed wheel IMO and a disk IOI9 bearing a pin I020 which coope ates with a pin I02I of the toothed wheel IOI1. A rack bar I025 meshing with toothed wheel I 0| 3 is controlled by a link I025 coupled to a crank disk I021, which executes one revolution in each cured by a pin to a shaft I021a, which has fixed to it a crank I208. A connecting rod I209 couples crank I208 to a crank I201 fixed to main drive the gear IOI1 revolves counterclockwise and the pin I 02I travels from the position shown in Fig. 3 away from the pin I020, the disk IOI9 remaining stationary during this operation. When the operation of the machine begins, the rack bar I025 is then to the right. During the leftward movement of the rack bar the disk IOI9 is rotated in clockwise direction and the pin I020 engages pin I02I and restores it to the position shown in Fig. 3,
thus rewinding the spring IOI3. The unwinding of the spring I M3 is limited by the path of movement of the pin I "I slightly less than 360, and since the opposite end of spring "I3 is anchored to stationary post IOI5, the'spring is always re- This mecha- 0 The spring barrel IOI2 30 During the table-moving operation 60 rack bar I033 to hold the printing table stationary during the machine operation.
It will be observed in Fig. 1a that the two parts 912 and: 913 of'the account card are relatively offset and are joined by an incline. This shape of the edge of the card is produced by cutting off a part of the margin at each printing operation. For this purpose the following mechanism is provided: A stamp I 041 andcooperating matrix I040 are positioned at the margin of the card near the feelers 914, 915. The stamp I 041 is connected to a lever I049 at I050. The lever I049 is pivotally mounted at I049a and is pulled by a spring I05I so as to coact with a cam disk I052, driven from the main drive shaft 804, by connections not shown in the drawings. Before the cutting mechanism is operated, the feelers 914, 915, are removed from operative position to the position shown in Fig. 8. For this plupos'e there are mounted upon the links 980, I, ears I04I,
I042, which cooperate with the nose I043 of a bell main drive shaft 304.
The spring IOI3 is normally acting to press the stops 989a and 990a against the ledges 954a and 9831:, with a pressure which would interfere with a free movement of the feeler mechanism to the inoperative position shown in Fig. 8. For the purpose of retracting the stops 989a. 990a, there is fixed to shaft I 005 a star wheel I024, provided with three teeth, each adapted to coact with a shoulder I023, formed by a. notch in disk IOI9. The shaft I005, it will be remembered, has fixed ,to it a gear IO0I which meshes with The connections between the star wheel I024 and the locking disks 999, 990, are such that whenever 999a and 990a are in contact with ledges 984a and 983a, one or another of the teeth 'of star wheel I 024 stands in the path of shoulder I023. Thus when the disk IOI9 begins to rotate in clockwise direction, by the leftward movement of rack I025, the star wheel I024 is rocked through asmall angle, suflicient to raise the stops 909a, 9900, from the ledges 994a, 903a, .as shown in Fig. 8.

The movement terminates when the feeler 914 rides up on to the edge 912 of the card and swings the locking dog 984 to the position shown the card is too far up with respect to the printing mechanism, the locking dogs 983 and 004 are moved by the feelers 915 and 914 to the positions shown in Fig. 6. In these positions the stop 909a is blocked, while the stop 99011 is released. Consequently the table-moving mechanism is set in operation to move the table to the right, as indicated by the arrow in Fig. 6, the movement being terminated when the feeler 915 rides down on to the edge 913 of the card 915, which shifts the locking dog 983 to the position shown in-Fig; 4, where it intercepts the stop 990a.
At the same time the printing table is being moved by spring IOI3, the wheel IOI1, which is geared to the spring barrel, is rotatedby an (Fig. 3), distance corresponding to the extent of movement of the table.
This movement is preferably at least suflicient to allow the printing table to travel from one end position to the other.

In the course of the following machine operation the movement of rack bar I025-to the left rotates disk I M 9 clockwise and pin I020 engear I II! to the position shown in Fig. 3, rewinding the spring IOI3.
In the state of rest of the machine, when no d is inserted, the releasing lever I202 is blocked by pin I200 and the slide II9I is blocked by pin H92 against upward movement. At this time thepin N92 is in its extreme left position, blocking key H90, and the lever I003 is in the left hand position marked locked. when a card is inserted with the table in such position that the feelers engage'the card as shown in Fig. 5. the lever 1003 remains in the left hand position and the slide I I 9| still blocks the key 90.
