When the handle is turned the unit (A & B) turns the shaft (C)
Part (A) has a pin on each end
The pins engage with arms (E)
This causes an intermittent motion on secondary shaft (F). (D) locked against (B)
holding shaft (F) in position movements
The other end of (F) is a pentagon (REAR G Lower picture) eccentrically mounted on
the shaft
As it is turned it makes the film holder (H) rise & fall, stopping at the four positions
corresponding to the four rows of frames on the film
Downward movement of the film is assisted by spring (J)
The worm gear on the end of shaft (F) imparts movement to spindle (L) by means
of gear (K)
The sprocket teeth on this spindle slowly turn & move the filmstrip horizontally
On the end of shaft (C) a two bladed shutter (REAR R) gives a small amount of light cut off during the movement of the film up & down
A 6 volt bulb, and a condenser lens (REAR S) are fitted behind aperture (M)
The lens (N ) is fitted to a sprung lens holder (P)
Framing is by knob (Q)
