MACHINE FOR CALCULATIVELY INTERPRETING PEREORATED CARDS Filed March 1,1928

ATTORN EY- Patented July 4, 1933 UNITED STATES PATENT OFFICE GUSTAV TAUSCHEK, or VIENNA, AUSTRIA, ASSIGNOR TO THE TABULATING MACHINE COMPANY, or ENDICOTT, NEW YORK, A CORPORATION OF NEW JERSEY MACHINE FOR CALCULATIV ELY INTERPRETI'NG PERFORATED CARDS Application filed March 1, 1928, Serial No. 258,239, and in Austria March 24, 1927.

This invention relates to machines for calculatively interpreting the values represented by the perforations of perforated cards and has particular reference to a devlce by means of which it is possible to add the numbers represented in a plurality of card fields of a single card, each field preferably constltuting a number of columns. By means of such a device, it is, for instance, possible to automatically determine the final sum to be paid a workman which is the result of the summation of the values represented by a plurality of card fields, designating, for example, wages, additional wages, compensation for over-time, etc.

The essence of the invention resides in the feature of having only one group of analyzing brushes relating to a particular card field connected at a time to control the entries in the accumulator, and after analyzing this card field, a connection between the analyzing brushes for the next card field 1s established to control the entries designated by the second card field in said accumulator, so that after a successive number of such analyzing operations, corresponding in number to the card fields, the result of such analyzing operations is represented by the accumulator.

The device constructed according to the invention may be mechanically or electrically operated.

The accompanying drawing represents one embodiment of the invention shown as employing electrical operation.

In said drawing:

Fig. 1 is a perspective view of one form of the invention.

Fig. 2 is a view of card shown perforated according to the Tauschek system to rep resent seven arbitrary values corresponding to a like number of card fields.

Fig. 3 is a view illustrating a modification of certain electrical connections employed.

Fig. 4 is a detail of a shaft return device.

The card 1 shown in Fig. 2 is perforated according to the Tauschek system, the digital value of each column of perforations being suitable means in the direction of the card columns, and in only one direction of movement the brushes sweep over the card and engage a metal plate 1 through the perfora-' tions. The metal plate 1' is connected to the negative line side of battery B. I

In each extreme position of the yoke 2, contacts 2' thereon contact-one or the other of contacts 4 and 5, both of which are electrically connected to one side of a magnet 6, the other side of the magnet being connected to the positive side of battery B. The negative side of the battery leads to the contacts 2', to therefore result in the energization of the magnet 6 in each extreme position of yoke 2.

The extension of the armature of magnet 6 operates a pawl 6' pivoted thereon so as to turn a ratchet wheel 7 a step for each energization of magnet (3. Ratchet wheel 7 is secured to a shaft 8.

Arranged upon the shaft 8, in radial alignment or in one plane, are radially extending contact arms or blocks 9. The shaft 8 is surrounded by a cylinder 7 of insulating material which is coaxial with shaft 8. The inside of the cylinder carries as many groups of contact blocks 10 as there arecard fields, each group parallel to shaft 8 being connected by a series of wires 8' to the related set of brushes 3.

The connection between the brushes 3 and the contact blocks 10 is such that the contact blocks 10 related to the brushes of one card field are arranged upon a generating line or element of the cylinder. The lines of the cylindrical contact arrangement are thereby carried by the shaft 8 will contact with a formed by as many contact blocks 10 as there are columns in a card field, while upon a 011'- cumferential line as many contacts blocks 10 are provided as the perforated card hasfields, seven as shown by way of example in Fig. 2.

Each of the contact blocks 9 of the shaft 8 is, by means of a conductor 9 connected to one side of the related magnet171 of the accumulator 29 which, in the manner fully explained in Patent #1,617,088, controls the entries in the related elements 172 of the accumulator. Therefore, impulses are directed by conductors 9' to cause energization of such magnets 171, as the other sides of all magnets 171 are connected to the positive line side of battery B by a wire 171a and which common return wire 171a may be enclosed in the cable with the conductors 9', as shown in Fig. 1.

The preferred form of accumulator 29 comprises that shown in the British Patent #289,055 and is also shown in Fig. 1. In the manner described in the British patent and Patent #1,617,088 the magnet 171 of the related accumulator wheel 17 2 is energized by electrical impulses as often as contact is established by means of the related brush 3 of the set which is in use entering a card hole. Each of the brushes 3 of the set in use is, of course, as stated, in series connection with the related magnet 171 of the series. In order to effect the entry, each accumulator wheel is provided with a ratchet wheel 151 which is engaged by a pawl 161 connected to the armature of the associated electromagnet 171. This pawl is suitably spring pressed to engage the ratchet wheel 151 and the usual retrograde preventing pivoted pawl 174 may be used to prevent backward turning of wheel 172.

The energization of magnet 171 causes the pawl 161 to be operated to such an extent that the ratchet wheel 151 is turned a distance of one tooth.

The transfer mechanism is fully explained in the British Patent #289,055 and as described briefly herein comprises a pawl 181 which is rocked clockwise when a wheel passes through zero thereby withdrawing its projection 182 from a projection 183 of a lever 184 which is thereby rocked so as to prepare a circuit to the next higher order -magnet to effect a transfer.

The brushes 3 and the contact blocks 10 carried by the cylinder may be plugged by employing any conventional plugging devices such as a plug So at the end of a conduc'tor 8' and a jack 8b which is electrically connected to the related one of the brushes 3. By plugging in any desired manner control operations by any field may be excluded, or the order of analyzing the fields may be altered.

After the complete analyzing of the card by the sets of brushes 3 the shaft 8 will be so turned that a radial contact element 11 contact block 12 thereby closing a circuit of the magnet 19 (which will not be traced as it is obvious) to cause energization of the same.

A casing 13 is provided (see Fig. 4) in which is fitted a coil spring 13 similar to that employed in typewriters for shifting the carriage, the spring 13 being wound as shaft 8 is stepped. One end of the spring 13 is secured to the shaft 8 and the other end to the casing 13 and the latter is held stationary with respect to shaft. 8. This is preferably ell'ected by having integral ears 13a (Fig. 4) of the casing 13 receive a pair of stationary studs or rods 13?). Each successive position of the shaft is maintained by a spring pressed pawl 14 cooperating with ratchet wheel 7. Vhen the-magnet 19 is energized it rocks a double lever 17 pivoted by a rod 18. Lever 17 carries two pins 16 and 15, the former disengaging pawl 14 from ratfhet wheel 7 and the latter disengaging paw 6' from ratchet wheel 7 and only when lever 17 is rocked.

-At other times pins 16 and 15 permit e11- gagement of pawls 14 and 6' with the ratchet wheel 7.

lVhen both pawls 6 and 14 are shifted the coil spring 13' in the casing 13 will be effective to return shaft 8 and contact blocks 9 to normal position at which time the contact blocks 9 are correlated with the first set of contact blocks 10.

In accordance with the modification disclosed inFig. 3 contact blocks 10 may be carried by a closed cylinder 7 so that after shaft 8 with the contact blocks 9 occupies its extreme rotated position it need not be returned to normal by a rotation in the opposite direction, but may be brought to the starting position by simply turning shaft '8 a step in the forward direction. In this case the conductors 9' between contact blocks 9 and magnets 171 of .the accumulator cannot, of course, be used as shown, and collector rings 9a are preferably provided on a cylinder which may constitute shaft 8.

In the modified arrangement contact blocks 9 are connected to collector rings Or; by conductors 9?) preferably within the cylinder which may constitute shaft 8. lVhen such a construction is employed the release mechanism comprising elements 15, 16, 17, 18, 19 are not necessary.
