874 HANDBOOK OF PROJECTION FOR in the projection room, or elsewhere, or may be controlled from two different points. This forms an ideal installation, because with the switch conveniently located in the projection room, where it may be reached from working position beside either projector, UKprojectionist can close the curtain machine switch and start his projector at the same time, whereupon the title of the picture is projected on the curtain, and is gradually revealed on the screen as the curtains are pulled away, or as the curtain is raised by the machine, as the case may be. In Fig. 365 we have a diagrammatic representation of the device, its location, and the cable arrangement and connections with the curtain. The machine may either raise and lower the curtain, pull curtains sidewise, as per diagram, or it may loop them up and back them away from the screen. The practice in many of our best theatres is to suspend cloth curtains down over the screen from above, and to disclose the screen by draping or looping them back sidewise.
