Abstract: An improved voting machine particularly suitable for use in harsh environments is disclosed which features a control box which is operated by an election official individually activating the machine before each vote is cast. The control box may be disposed at a distance from the voting machine and is connected thereto by a permanently attached flexible cable, whereby the machine is rendered essentially foolproof yet durable in service. The machine is provided with first locking means to enable viewing of the tallies on the vote counters and second locking means prohibiting resetting of the counters except by authorized persons. A counter is also provided to provide a count of the number of times the tallies are reset to zero.

Abstract: A compact, versatile voting machine is disclosed having adaptability for use with various vote registering devices such as tally counters and punch card apparatus. The voting machine includes a selector mechanism having a series of parallel columns housing voter operated key slides. A vertical interlock mechanism includes ball housing blocks which are alternately disposed between the key slides and house displaceable interlock balls in a tool line. The cam blocks are adjustable to limit the effective length of the tool line to establish groupings of candidates from which a single selection can be made. A magazine at the top of each column is adjustable to permit multiple selections from a grouping. Actuation of a key cams the interlock balls into the tool line, and when a predetermined number of voter selections have been made no additional keys can be actuated as they are blocked by the tool line.

Abstract: An electronic voting machine includes a number of terminals to facilitate accommodating virtually any ballot with nearly the minimum amount of apparatus for the particular ballot. A display lists the candidates for each office beside an identifying tag. A poll worker actuates a switch which enables the apparatus to receive vote selection indicated on a keyboard by the voter. The voter operates a switch to identify the office or issue being voted and then enters his choice on a keyboard to cause a signal representative of his selection to enter a temporary storage means and be illuminated on a display means. The voter turns a switch to the office or issue voted upon, enters a number representative of the candidate or issue decision selected and sees his vote displayed as it enters storage.
