Abstract: Voting machine or system for both punching holes in a ballot and at the same time accumulating the votes. The ballots are fed into the machine, locked in place, and then tests are made to determine if the ballot is valid. If the ballot is valid, voting is accomplished by the user punching holes in the ballot. The punching of holes also produces storage of the vote which is thereafter accumulated in the machine after the ballot is approved by the voter. The machine also includes means to permit a voter to detect the he or she has overvoted a ballot and thus produced an invalid ballot so that a new ballot may be taken and voted.

Abstract: A machine that quadrates documents comprising a stationary plate having along one edge a plurality of transversely-spaced cutting edges defining a cutting area, a rotor having axially thereof and radially-spaced from its axis a plurality of complementary cutting edges supported for rotation with the rotor about an axis parallel to the edge of the stationary plate for movement of the cutting edges in shearing relation to the cutting edges on the stationary plate and sheet-feeding rolls for advancing the documents to be quadrated along the surface of the stationary plate onto the cutting area to present a portion thereof to the cutting edges in timed relation to movement of the cutting edges into cutting relation with each other.

Abstract: A screw having its head shaped to prevent its removal by unauthorized persons, characterized in that it has peripherally thereof an odd number of sides arranged symmetrically with respect to the center of the head and inclined to the axis of the screw to prevent removal of the screw by the use of pliers. The screw is removed by the use of a matching socket wrench.
