` 2 Claims. 3f-,This invention relates to tabulating machines employing record cards and deals particularly ,i with a multiplying machine of the type shown in latent Number 2,165,230, granted July ll, 1939,

to J. M. Cunningham.

lThe invention to be hereinafter described is an addition to machines of the above character, which in practice will eliminate one or more operations required under the ordinary use. The present record card controlled machines used for multiplying are so constructed that in the field in the card where recordings are to be made the machine will record zeros until the first signicant figure appears. It will be understood by those skilled in this art that the multiplying machine referred to will record a result in a predetermined iield, which field can be used to f control a check Writing machine and that when the card is later used to control a check writing machine the Zero recordings ahead of the signicant figures in this eld will be ignored by the check writing machine. To print the customary asterisks or stars ahead of the significant figures on the check, the usual practice is to sort thel responding to the number of zeros ahead of the iirst signifcant iigure, said recordings being positioned to operate magnets on the check writing machine that cause the machine to print asterisks or equivalent signs.

Under my invention a change over device is incorporated in the multiplying machine that will change over the connection from the read out to the zero magnet, so that the zero magnet will not respond to the read out but an auxiliary magnet in the multiplying machine will be energized instead. The auxiliary magnet referred to is one of the extra magnets incorporated in a multiplying machine as standard equipment and is arranged to cause recordings above the regular ileld in the card. Normally it is not used in the regular machine operation. After the change over has been made the auxiliary magnet will be operated by the zero connection to the read out untila positive number is reached in the read out, whereupon the change over will switch the connection back to the zero magnet and zeros will be properly recorded for the remainder of the iield in the card. The result is a series of signs on a check. The device may be installed upon a standard multiplying machine and operated without affecting any other parts or operations of the machine except those specically mentioned. The recordings mentioned herein are the conventional holes punched in record cards by a plurality of punch magnets under control of the read-out lines.

In the drawing I have shown a simplified illustration of how my invention may be applied to a conventional multiplying machine of the type shown in the above mentioned patent. Figure, l is a wiring diagram showing the selector magnets with my change over device incorporated therein; Figui-e2 shows a fragmentary part of the multiplying machine in conjunction with an auxiliary circuit for operating the change over device shown in Figure l; and Figure 3 shows a conventional payroll card.

Briefly stated, my invention consists of an automatic change over device between the zero magnet and an auxiliary magnet whereby the read out circuit normally connected to the zero magnet may be switched over to operate the auxiliary magnet. In the drawing I have shown a series of selector magnets designated to 9 inclusive, and l i and i2. These magnets correspond to the magnets designated 23 in Patent Number 2,126,595 granted August 9, 1938, to H. Weinlich et al. In Figure 2, I have generally designated these same magnets 126. With respect to the magnets, it is to be understood that the ordinary multiplying machine carries twelve magnets, ten oi which are used to punch holes corresponding to numerals, and two of which, namely i l and i2, are usually not employed in the ordinary multiplying operation. In my invention I utilize one of the magnets, either l l or i2, in this instance magnet l2, for my purpose, and whenever the magnet i2 is mentioned herein it is to be understood that this term is intended to include any magnet that causes a recording in the card above the regular field. Referring again to Figure l, it will be noted that one side of the magnets, 0 to 9, inclusive, are connected to conductors Il to 9 respectively, which lead to their respective connections on the read out device and correspond to wires 52 (Fig. lb of the Cunningham patent mentioned above). Since this invention is concerned solely with an addition which aects only two of the magnets, and since the operation of the invention is not dependent 'upon nor is connected with any other electrical operation of the machine, the description will not include operations of other parts of the machine but will be confined to that part only which is aiected. The read out device mentioned herein corresponds to the conventional circuits illustrated in Fig. 1b of the same Cunningham patent. It will be noted, with respect to Figure 1, that the lower side of the magnets I to l, inclusive, are connected to a line Il and that the lower side of the magnets Il and I2 are connected to a line Il. Both lines I3 and Il are connected to line 5l, which corresponds to line 54 of Cunningham. In the line I3, I incorporate a relay coil B.

Referring to Figure 2, it will be observed that I have shown fragmentarily a machine embodying the aforementioned selector magnets I20 and a card carrier rack 'Il which corresponds to the card carrier rack 14, shown in Fig. 16, of the Weinlich patent. In conjunction with the card carrier rack, I incorporate a ycircuit comprising switch S, key K, relay coil A, contact points IA, contact points IB, and key L. The circuit is connected to the same source of supply through line 54 and line 55. It will be noted that key K is paralleled across the contacts IA, the purpose of which will become apparent presently. It will,

also be observed that the coll B is Aparalleled by contacts 3A and that double contacts 2A are arranged in the line II' connecting the II magnet to the read out device so that the control time the contact points 3A will close and shunt out the coil B and the magnets II to 9 inclusive will then operate in the conventional way. Ar the rack continues to travel, it will encountex and open the switch L, thus breaking the auxiliary circuit independently of the key K and the contacts IA. It is to be understood that the switch L is a precautionary switch and is placed in the circuit merely to insure that the circuit will be opened at the end of the card travel in case no significant figures appear in the check writing field. The result, as shown-on the card C, is a series of recordings I6 in the upper portion of the card above the regular control eld, said recordings being arranged to control punch magnets in a check writing machine which, as before stated,'have been adapted to print the desired signs such as asterisks or stars.

The above described operation whereby zero recordings in the check writing ileld are converted into other recordings outside the regular ileld to control magnets in a check writing maof the read out device may be switched from the 0 magnet to theV I2 magnet and vice versa. On the card carrier rack 14, I mount a fixture M, which in this instance is shown as a form of an extending arm that is adapted to engage and close the key K as the rack travels a predetermined distance, which distancefis determined by the fleld on the card that controls the check writing machine. The key L is also arranged to be engaged and opened after the rack travels a predetermined distance beyond the closing of the key K.

In operatin, a record card having items punchedin different columns, such as is illustrated in Figure 3, is fed into the multiplying machine by means of the rack 14, and the machine calculates the various items and as the card travels records a result in the check writing field designated I5. In recording the result in the check writing field, the multiplying machine under the ordinary set-up will record zeros until the first significant figure is reached, whereupon it records the actual amount carried over into the field. According to my invention, as the card carrier. rack 'I4 carries the card C into the machine, the arm M will engage and close the key K as the check writing eld I5 enters the recording position in the machine. Assuming that the switch S is closed, the coil A will become energized and will close the contact points IA, thus forming a circuit independent \of the key K, which by virtuelof the travel of the carrier rack 'Il is only momentarily closed. At the same time coil A operates contacts 2A, which disconnects the Il magnet, and places the I2 magnet under control of the read out; Also, contacts 3A are opened, thus throwing coil B in` series with line I3. According to this circuit, any impulse from the read out `normally transmitted to the 0 magnet will be transmitted to the I2 magnet instead. As`explained hereinbefore, the I2 magnet is arranged to cause recordings in the card above the regular field, which recordings are subsequently used to operate magnets in a check writing machine that prints asterisks or equivalent signs on a check. This arrangement will hold until any one of the other magnets from I to 9 are energized, which will in turn energize the coil B and break the contacts IB, thus deenergizing the coil A and allowing the contacts 2A to swing back and connect' the zero magnet to its proper read out connection. At the same chine for the purpose described is automatically performed in the multiplying machine, thus eliminating sorting and rerecording of the cards before use in the check writing machine.

The means employed for the purpose is simple, inexpensive, and may be incorporated in a conventional multiplying machine with minor alterations.
