Abstract

This machine, basically a perforated card verifier, is adapted to check the answers of a student. A shield 10 is placed over the card path and additional relays are used in the control circuitry. Normally, a card to be verified is fed from hopper 12 to sensing station 14. Here, pins set up a circuit which is completed by the operator depressing a key in keyboard 15 that corresponds to the data sensed. If the data represented by the pin and key are in agreement, the card is fed to the next column. If not, the card remains stationary and a signal is given.

Self-teaching Machine

This machine, basically a perforated card verifier, is adapted to check the answers of a student. A shield 10 is placed over the card path and additional relays are used in the control circuitry. Normally, a card to be verified is fed from hopper 12 to sensing station 14. Here, pins set up a circuit which is completed by the operator depressing a key in keyboard 15 that corresponds to the data sensed. If the data represented by the pin and key are in agreement, the card is fed to the next column. If not, the card remains stationary and a signal is given.

There are four types of cards. An information card 16 carries a printed statement as to the scope of the subject being studied. A second card 17 has a question printed on one half and a field of perforations representing the answer together with explanatory matter printed on the other half. A third card 18 is similar to card 17 except it may contain an eleven perforation 20 in the first column or a twelve perforation 21 in one of the columns after the answer field.

The fourth card 22 has a pattern of over perforations in the answer field permitting alternate answers such as home or house, pig, cow or horse, etc.

In operation, the student actuates feed key 23 and an information card is fed into reading position between sensing station 14 and frame member 24 under control of program drum 11. After reading the instructions, the feed key is again operated, feeding a question card 17 and informat...
