39/KODAK M-SERIES PROJECTORS
Two movable cam followers (one for each claw) are
located conventionally between the claw and the in-and-
out cam, Fig. K6. Both are in constant contact with the
cam and both are positioned by a speed-shift lever so that
they follow one of 4 tracks on the face of the cam. There
are only 2 tracks on the M85 cam.
In position #1, Fig. K5, regardless of which claw is
"working," the projector is in "still" because the follower
does not drop in any of the detents as the in-and-out cam
rotates.
Position #2 gives 6 frames per second because the
follower drops in only the longest detent, once per
revolution of the 6rps in-and-out cam.
6rps X 1 detent = 6 frames per second
Position #3 gives 18fps because the follower drops in the
2 intermediate detents, plus the longest detent, on each
revolution of the cam.
6rps X 3 detents = 18 frames per second
Position #4 gives 54fps because the follower drops in the
6 short detents, in addition to the 2 intermediate detents
and the 1 long detent, on each revolution of the cam.
6rps X 9 detents = 54 frames per second
The M85 has positions #1 and #3 only.
This operation can be observed by removing the base and
rotating the shutter shaft by hand. To prevent damage to
the mechanism, the shaft must be rotated counterclock-
wise only. Or use a strobe lamp set at a slightly lower rate
than necessary to "stop" the motion.
Film Selector
The selector knob, Fig. K7, determines whether the super-
8 claw or the regular-8 claw is in the operating position.
One window in the control panel plate indicates which
film (super 8 or regular 8) the projector is ready to accept.
The two remaining windows indicate
Forward and
Reverse settings of the speed-control knob.
