which receives current from the genera.tor M 

When attia.cted by the unbalanced action of

Serial No. 6980, filed February 5, 1925 now 

Patent No 1,762145, dated June 10, 1930 

For SlID.phcity of illustration the alternatmg current control has been made entirely 

separate from the regular D C card urcmt TO 

and ma.chine control The A C and control 

circuits are shown by heavy Jmes Similar 

reference characters a.re employed as on Fig 

1 so far a.s possible From contact blocb 

15 and 16 suitable cable connections are shown 76 

leadmg to the opposed wmdmgs 17 a.nd 18 

In order to ut1hze selective columns and for 

suppiessing the operation on desired columns coils 17 and 18 are not permanently 

connected to the common return lme 19 lead- 80 

mg to the ground but instead are connected to 

individual plug sockets 31 Corresponding 

plug sockets 32 a.re provided m the return lme 

19 which leads to the ground By employing proper plug connections between the de- 8& 

sired sockets 31 and 32 the desired ddferentlal 

opposed magnets 17 and 18 can be brought into mrcu1t Thus the control may be used on 

a less number of columns than the eight which 

a.re illustrated or any desired column can be DO 

cut out of controlling action It is obvious 

that instead of emplo.ymg the md1v1dual relays 21 a common relay armature such as 21a 

may be employed The control c1rcu1t 74: extends to the usual control relays 91 and 84: 96 

of the ta.bulatmg mo.chme and maintams the 

oper.a.tion of the tabulating machme durmg 

the 'J>eriod of the cycle when cam contacts 

0-1 break Interruption of this control cir100 cu1t 74 bnnp a.bout a stoppage of the tabulatmg machine or otherwise modifies the operation thereof 

It is obvious from the above that the arri:mgement descnbed is capable of detectmg 105 di:flerences m successne cords of the smgle 

hole or Hollerith type In this type of cards 

double punchmgs frequently occur and smce 

they are usually m error it is desirable that 

attention be called to this fact Where two 

perforations occur m one card and one of 110 

these corresponds to a. perforation m a succesSive card magnet wmdmBS 18 and 17 wtll 

both be ene!"gized and machine operation will 

continue Ho"'ever the presence of any perforation m one card without a correspond- 115 

mg perforation m a successive card will be 

immediatelv sensed by either the up.Per or 

lower brushes and cause energization ol. 

e-Jther magnet 17 or 18 alone to alter machine operation This detection may be ef- 120
