The Carpenter
This projector is very similar to the American "Natco" machine, and is being manufactured in Britain by Carpenter & Richardson, Ltd., of Wembley, a well known firm of precision engineers.
The Carpenter is a "truly professional" model, and is fitted with all the usual controls so designed to give the operator a certain advantage in the way of "slickness" and showmanship. A most unusual feature, however, is that the operating-side of the projector is on the left. The sprockets are thus placed on the inside, away from the operator, and permit the film to be threaded without the surface being scratched — always a possibility with right-handed threading.
Designed on the unit principle, complete assemblies, such as the intermittent movement and the amplifier, may be speedily withdrawn and replaced, a job necessitating no more than the removal of one or two screws and easily accomplished by the novice.
The triple-claw action is extremely smooth and quiet. The claws engage with a sliding-movement three perforations at a time, and there is little danger of loss of hoop.
Illumination is from a 750-watt lamp set at right angles to the gate, and the light is reflected by an inclined mirror through double condensers to the projection lens. Lamps of either 500 or 1,000-watts may be used as alternatives. A 2" F.1.6 bloomed lens is fitted as standard, and others of various focal lengths may be supplied when required. The lamphouse is so constructed that a defective lamp may be swung outwards and speedily replaced within two or three seconds, the new lamp being automatically positioned when the housing is swung back into position. Picture brilliance is exceptionally good.
The Carpenter is also fitted with two motors; one to drive the mechanism, and the other the rewinding-device and blower. Both are high-speed synchronous-type A.C. motors. The movement of the reverse-switch disengages the take-up from the main
