Blue Seal's Superior Model A Projector

New Equipment Said to Embody Developments

V For Scientific Motion-Picture Projection

Blue Seal Cine Devices, Inc., manufacturers of high quality sound-on-film recording equipment since 1929, are the makers of the new Superior Model A 35-mm. projector. Following is the companyis textual presentation:

The older Model X and U projectors were manufactured by the Coxsackie Holding Corporation of Coxsackie, New York, since 1922. At the beginning of the war they disposed of their plant and Blue Seal Cine Devices, Inc., purchased the rights, patents, and tools. J. Burgi Contner, president and chief engineer of the Blue Seal, redesigned the projector to the present Model A, retaining all of

the finer qualities of the former projector and modernizing it to contemporary design and embodying all the advanced scientific development for modern day projection. (Figure 1.) The exterior appearance is attractive and finished in gray morocco (Figure 2) which matches other components necessary to assemble a complete projector. The film side (Figure 3) is roomy, easy to clean and service. The micrometer focusing large-size lens mount accom FIGURE leThe Model A Superior 35-min. projector retains the qualities of the earlier Model X and Model U. The design of the new equipment embodies all the advanced scientific and technical informae

tion and developmnts in present-day projection.

modates the new high-speed coated lenses without the use of adapters. The aperture plate is one-piece, hardenede and-ground construction. There are two sets of hardened-and-ground film shoes. The upper shoes effectively snub patches while the lower ones are long enough to hold the film fiat during the period that the film is at rest in the aperture. Dual pad rollers are used on both upper and lower sprockets. The Model A combination framing and pilot lamp is provided.

The drive side (Figure 4) is of simple straightforward design eliminating all unnecessary gearing. The vertical shaft carries the ball-type governor which controls the fire shutter. The rear shutter is driven directly from the cam shaft eliminating back lash and shutter oscillation.

Intermediate and main drive gears (Figure 5) revolve on fixed hardened and ground studs. By removing one screw shaft and gear, assembly can be removed from the frame. Shafts can be adjusted and locked in a position to eliminate end play. For replacement, both shaft and gear assembly can be replaced eliminating rebushing frames. All lubrication is done on the gear side with the exception of the intermittent movement. The old reliable oil can is used for lubricating necessary parts when and where it is needed. As most necessary equipment and sound reproducers require manual oiling, this is not an additional burden to the projectionist. All oil .cups are painted red which makes overlooking improbable.

The intermittent movement (Figure 6) is the star-and-cam, double-bearing type. End play in the cam shaft can be easily adjusted. The pad roller arm is a part of the intermittent movement. Two pad rollers are used which allow the film to move over the sprocket without friction. A fixed film snubber takes the slap out of the intermittent loop and steadies the picture without friction on the film itself. Movement can be removed from the frame in a few minutes.

Some of the main features of the Superior Model A are that it is a simple, rugged projector, a clumination of the most modern scientific engineering givr ing the maximum performance with a minimum of service. Exceptionally simple to operate with minimum of wear and maintenance.

This smartly designed projector can be disassembled and assembled with an ordinary screw driver in less than 50 percent of the time required for any other professional theatre type projector.

Mechanism fits all standard bases, magazines, sound heads and drives.

During the war Blue Seal produced intricate sound equipment for the Office of Strategic Services, the Marine Corps, Army Air Forces and other essential branches.
