which the unit operates.
Each is equipped with a colored filter or
filters and incorporates a clamp for mounting
on
the aiming post.
Note.
Batteries used in aiming post lights are issued by the Signal Corps. The
batteries are not considered as part of the equipment and should not be stored,
packed, or shipped in aiming post lights.
(1) Figure 4 illustrates the major components of aiming post
light M14. The case holds two dry cell batteries similar in
type to those used in ordinary flashlights. Each battery
enters from opposite ends of the case and is held in position
by spring pressure from a cap.
The lamp screws into
a
contact located on the reflector which fits into the case.
The
window is threaded internally to receive a filter assembly
which may be either red or green.
The purpose in supplying
interchangeable green and red filter is to distinguish between
far and near aiming posts during operation. Previously,
only one red or green filter was required to make a complete
aiming post light.
However, this has been changed and
future supply of aiming post light M14 will include both a
green and red filter.
One filter will be mounted in the light
and the other included in the aiming post light package. A
reflector shade fits over the filter and lamp. During opera-
tion, the aiming post light mounts on the aiming post by
means of a bracket fixed to the case and the light is turned
on or off by means of a toggle switch.
(2) Aiming post light M41 (fig. 5) utilizes the same basic major
components in its system as the aiming post light M14, with
the exception described in paragraph 5. Note that this light
utilizes only one dry cell battery and is supplied with one
filter only.
(3) Aiming post light M43 (fig. 6) is identical in operation to
aiming post light M14, described in (1) above. It utilizes
the same major components and has the same appearance
and construction with the exceptions listed in paragraph 5.
Note that this light is provided with a disk which fits
between the glass window filter.
The disk has a small round
hole in its center that provides the sole means for passage
of light from the lamp to the filter.
