Catalog of stereopticons, motion picture machines, projection apparatus : manufactured and imported by the McIntosh Stereopticon Company . .$$ 60 McINTOSH STEREOPTICON CO., CHICAGO, ILL,.. U. S. A. THE McINTOSH HAND-FEED ARC Direct Current For Alternating Current. PRICE of Mcintosh Hand-feed Arc Lamp only, for use on either Direct or Alternating Current $ PRICE of above, with No. 1 rheostat Ball hood for either direct or current, net . The Upright form of Hand-feed Arc Lamp is sometimes pre-ferred to the 90 Degree Form, particularly for use where currentgreater than 35 to 40 amperes is to be used. The Upright Arc Lamp is fed by single hand wheel which feedswith a rack and pinion adjustment, both carbons. The same lampcan be used with a different adjustment as illustrated for direct cur-rent and also for alternating current. Using more than 15 amperes of current, the Upright form of ArcLamp works very satisfactorily. It cannot be used with any degreeof satisfaction, attached to the incandescent socket, but requiresspecial wiring, because of the fact that it is necessary to use a heaviercurrent with it than can safely be drawn from the incandescent socket.
