OINBMACHINKRY FOR TUB PERSONAL MOV IK 533
important feature is the fact that the shuttle which actuates the film-moving mechanism can be adjusted to compensate for wear, ensuring permanent steadiness regardless of the age of the projector. The mechanism of the latest models is positively, geardriven, and extremely silent and accurate. The lamp-house is placed directly behind the film, with the shutter between it and the film, and, although the lamp used is only a 200-Watt bulb, the optical system is such that extremely brilliant results can be had even when projecting a large picture. The usual reverse mechanism is fitted, but, as there is no still-picture safety-shutter, single frames should not be held in position longer than 30 seconds. The rewind mechanism of the Victor is unique, for the spindles carrying the regular feed and take-up reels are extended on the opposite sides of their supporting arms so that one reel may be rewound while another is being projected — a very considerable advantage at all times, but especially so when a reel is to be repeated later in the same programme. A hand rewind is also provided. This projector is supplied in a carrying-case, the bottom of which is attached to the round base of the projector's pedestal to form a more convenient base; this base may be detached at will, however, as may the bottom of the pedestal, for which a large tripod may be substituted. The models of the Victor projector are available, differing only in finish and price, while special equipments are made to adapt either to different sources of current.
An excellent European projector is the Ensign "Silent Sixteen." This is a very fine machine, although it lacks some of the minor features general in American machines — such as reverse movement and a still-picture projection shutter — but its capabilities as a projector are in no way lessened by the absence of these niceties. It is of the pedestal type, with the motor mounted in the base. The units are conventionally arranged, with the lamp-house behind the film. The lamp is a 100-Watt bulb, but it is used in conjunction with a powerful condenser and a lens working at F:1.8, making possible a satisfactorily illuminated picture as large as 7x9 feet. One feature which particularly differentiates it from most American practice is the fact that all the electrical equipment and controls — the resistance-unit, switch, and lamp and motor-controlling rheostats — are grouped in a completely separate unit and may be located several feet away from the projector itself. Another unusual feature is the fact that instead of the safety-shutter's being translucent, though heat-proof, as is customery here, it is opaque, like the fire-shutters of theatrical projectors.
Two other European equipments deserve mention here, even though they are seldom seen as yet in America. These are the ZeissIkon (German) and the Bolex (Swiss) . The Ziess-Ikon projector is a fitting companion to the camera bearing the same name, which is already well known here. For a 400-ft. projector it is
