Uie three film trap muutiting screws, and<br />
next replaee the light shield. The Job has<br />
been completed.<br />
It IS of paramount importance the fire<br />
shutter assembly should be set correctly in<br />
order for it to function smoothly. To set<br />
the height of the fire shutter, loosen set<br />
screw i<br />
iKiK. 2. No. 12 at the top of the governor<br />
on the vertical shaft. This will allow<br />
the governor to be raised or lowered and<br />
also will raise or lower the fire shutter.<br />
When the proper shutter height has been<br />
obtained, by making the above adjustment,<br />
the set screw should be firmly tightened<br />
and no further adjustment will be needed<br />
for a long time. The height of the shutter<br />
should be adjusted so that it does not come<br />
into the light beam with the projector<br />
running and yet not high enough to touch<br />
the top of the heat shield, of course.<br />
MECHANISM THOROUGHLY<br />
TESTED<br />
Very thoroughly, each Century projector<br />
mechanism has been factory-tested and<br />
adjusted for perfect operation. The CC<br />
model, double shutter, has been projectiontested<br />
and timed before leaving the factory.<br />
II It is desired to check timing or to reset<br />
the shutters again idue to being out of time<br />
from parts replacement! , the writer of this<br />
department will be happy to send you complete<br />
instructions on correct procedure in<br />
tuning double shu^ers. Space will not<br />
permit us, at this writing, to present complete<br />
instructions.<br />
The maintenance of the double shutter<br />
unit is simply placing a drop or two of oil in<br />
oil cup<br />
I<br />
Fig. 1, No. 1 1 once a day. No additional<br />
lubrication will be necessary all day.<br />
NOTE— Kerosene or solvent should not<br />
be used for cleaning Century mechanism<br />
ball bearings. Century projector oil may be<br />
used for cleaning purposes but do riot soak<br />
ball bearings in oil. Any of the other parts<br />
may be cleaned with kerosene, but keep<br />
the fluid off the ball bearings.<br />
MINIMUM CARE<br />
REQUIRED<br />
COMMENTS—The Century projector<br />
very rugged in construction and requires<br />
only a minimiun of care and adjustment,<br />
and it will operate, with good care, many<br />
years without any parts replacement indicated.<br />
We have found, in the field, the<br />
Century mechanism giving flawless screen<br />
performance. The projector is of unit construction,<br />
and thus it is possible to replace<br />
any unit quickly and easily without any<br />
special tools. By following the instructions<br />
in this article, it is impossible to reassemble<br />
the mechanism incorrectly<br />
<<br />
the two<br />
illustrations clearly show all the parts and<br />
units 1. In case of any rare problem, or<br />
any adjustment not covered in this article.<br />
the writer will be glad to assist you.<br />
The Century company has a very interesting<br />
development which has been adopted<br />
in the intermittents used with the horizontal<br />
VistaVision double-frame, pull down<br />
mechanisms. This movement operates in<br />
a vertical position. Ordinary oil with vent<br />
holes, etc., would leak and entirely run out.<br />
To overcome this problem. Century selected<br />
a new lubricant which Is not a<br />
mineral and one which has no change<br />
is<br />
Out in the field we hove run into ieyeial complainti<br />
from exhibitors that they could not iccure a steady<br />
picture nor a sharp focus when using CinemaScope<br />
lens on either a regular or Super Simplex or f-7.<br />
Due to the length and weight of this lens, ordinary<br />
lens mounts will not do os they will not hold (he<br />
