July 4, 1944. D. J. oLDENBooM CIRCUIT coNNEcTING DEVICE Filed Oct. 29, 1940 ya? I ENTO'R ATTORNEY pins Il and i8 engage the marking positions and, where a mark is found, the related pins IB and Il are electrically connected through the mark. Pins Il are connected together and to a battery I1 by a wire Il, while each pin Ii is connected to related resistors Il of 2 megohms each. The omaosite side of battery I1 is connected to a pair of parallel ammeters 24 which through resistors 20 connect to terminals 2|. Resistors I9 connect to terminals 22.

1f now the sheet I! is placed against the terminals as shown and a switch 23 is closed, a circuit will be traceable from battery I1, switch 2l, wire Il, pin I5 in the "2" position, mark R2, pin Il. resistor i! to terminal 22 (second from the top). conductive areas i2 through the sheet III, conductive line i4 to the upper of the lower two areas Il, back through sheet II) to the opposite area I3. terminal 2 I, resistor 20, the Wrong" meter 24 and back to battery I1. The deflection of the meter needle indicates that the examinees response is wrong. It, can be readily seen that, if mark R2 had been made in the l position area R I, the circuit would be directed through the Right meter 2l to indicate a correct answer.

A particular feature of the invention resides in the so-called self-seating capability of the sheet I0. The sheet I being of flexible card stock, the inked areas will securely contact all of a great number of pins 22 allowing slight deviations in the pin lengths, which deviations could not be permitted in former rigid panels without the use of adjustably seated plug Jacks.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made 'by those skilled in the art without departing from the spirit of the invention. It is the intention therefore to be limited only as indicated by the scope of the following claims.

What is claimed is:

1. A circuit connecting device comprising a. flexible sheet having a plurality of index point positions on both sides, with the positions on both sides coinciding, said sheet being punctured at its index point positions and covered with conductive ink over a delimited area surrounding one or more positions, said ink penetrating the punctures to conductively connect the areas of conductive ink on the opposite sides. i

2. A circuit connecting device comprising a sheet of flexible insulating material having a plurality of index point positions, said sheet being punctured at all said positions, a delimited area on each side of the sheet surrounding a single punctured position, being covered with colloidal graphite completely penetrating the puncture to form an electrical connection between the areas on both sides of the sheet.

3. A card for controlling the operation of a statistical machine, said card having columnsV and rows of index point positions surrounding each of which positions there is a deposit of conductive ink on both sides of the card, and means comprising conductive ink for causing any pair oi opposite deposits of ink to be electrically connested directly through a puncture in the card at the related position whereby electric current may pass through the card at such position to control the machine in accordance with the position in which such connection is made.

4. A card for controlling the operation of a statistical machine, said card having columns and rows of index point positions surrounding each of which positions there is a deposit of conductive ink on both sides of the card, a puncture smaller in area than the ink deposits being made in the card at any index point position, and conductive ink in said puncture to electrically connect the opposed deposits whereby electric current may pass through the card at such position to control the machine in accordance with the position in which such connection is made.
