Perkins Brailler Braille for blind w dust cover' Description You are bidding on a guaranteed working! Perkins Brailler, with a dust cover. This is a typewriter for the blind. The machine is in excellent working order. The outside surface is in like new condition. This is the most known and reliable manual Braille writing machine.    The Perkins Brailler is astonishingly complex, containing over 500 parts. The need to position heavy paper precisely is achieved by rolling the paper onto an internal drum, unrolling it when the user presses a line-feed key, and using a clock-like escapement to move an embossing carriage over the paper. A system of six cams consisting of rods with a square cross-section transfers keystrokes to the wire-like styli contained in the carriage.
