    Physical Description
    Mechanized, slotted punch card sorter resting on a gray painted metal frame with legs. The frame of the sorter is a large flat piece of gray painted metal with 4 cabriole style legs. There are two large cylindrical metal rods that run horizontally between the 2 front and 2 back legs. The sides of the frame have a large oval cut out and the left side has a rectangular metal plate attached to the inside to cover the opening. On the left, bolted to a black metal plate that spans across the cylindrical bars, is a black metal motor. The motor has rounded ends and a silver metal plate mounted to the front. On the left end of the motor is a metal rod and circular disc with a rubber belt that extends upward into the frame. A thick black electrical cord runs from the back of the motor up inside the frame across and down into a gray metal electrical panel box that is mounted to the right side of the frame. On the exterior of the metal box, protruding through the oval shaped opening of the frame, is a small black metal box with a circular label and 3 buttons. Resting on top of the frame are 13 hourglass shaped vertical metal pieces that form 13 slots each containing a vertical, cylindrical metal bar with an angled piece of metal resting on top. Below the slots, on the front of the frame, are two white rectangular metal strips with cut out numbers and a letter that correspond to the slot openings. To the right of the slots is a metal crank and several mechanical boxes including a small gray metal box with 2 thumb levers, a black metal rounded front box with a counter window switch and knob, and a circular metal box with hinged lid containing a metal dial. On top of the black box, between 2 vertical silver metal v-shaped extensions and a vertical painted and silver metal piece, rests a flat wooden plate with a circular knob handle. On the back of the black box is a hinged, semi-circular painted metal cover that flips up to reveal a round cast iron handle. On the back right of the frame is a metal plate with a series of numbers. On top of the slotted midsection is a long metal strip that runs horizontally between 14 pairs of rollers. The top rollers consist of a metal rod with round black rubber roller ends and the bottom rollers consist of a metal rod with silver metal roller ends. Resting on top of the rollers is a thick piece of glass with a thick aluminum metal rim along the back and sides. There is a thick black electrical cord with a large green plastic plug bundled and attached to the back of the frame. There are some areas of paint loss on the frame bars and the glass is heavily scratched.
