37. The sight angle bevel gear brackets, shownon drawing
number 231683, are identical right and left except for a
grease hole on opposi te sides. Each is a phosphor bronze casting
which combines a bevel gear housing and bracket in the
function of connecting the vertical sight angle shaft to the
rear to forward section of the sight angle cross shaft. The
brackets are mounted on an extension of the sight setter's
roof girder at pan floor level and are connected by flexible
couplings to shafts from their respective sight angle, gun
elevation, and turret train order bevel gear housings, also
by universal joints to shafts from their respective sight angle
bearing brackets and sight angle synchronizing clutches.
38. The turret train order upper bevel gear brackets,
drawing number 232403, are identical right and left assemblies.
Each consists of a phosphor bronze housing bracket,· covers,
shafts, and bevel gears. Each functions to connect the vertical
section of the turret train order shaft to the rear to forward
section of the cross shaft. They are fastened to a plate
on the circular girder and connect by a flexible coupling to
a shaft from the sight angle, gun elevation and turret train
order bevel gear housing and by a universal joint to a shaft
from the turret train order bearing bracket and trainer's
station.
39. The sight ang l e and gun eleva t ion order cross shaft
brackets, drawing number 231164, are three identical assemblies
each serving in the combined function of a bracket, bevel gear
housing, and cross shaft bearing for the sight angLe and gun
elevation order shafts. These cast phosphor bronze brackets
are mounted on a beam suspended between the gun girders above
the pan floor, right and left and on a support plate bracket
center.

40. The turret train order selector clutch, drawing
number ~3ll62, a combination of two jaw type clutches and a
bevel gear arrangement, functions to provide for selecting
control from either right or left trainer's station. The jaw
type clutches are each composed of a movable jaw, spline mounted
on its train order cross shaft, and a combination jaw and
bevel gear, bearing mounted on this same train order shaft and
geared to the shaft from the turret train order lower gear
bracket. The two movable jaws are fork positioned, the forks
being connected and controlled together by a sector gear and
spur gear on a shaft from the control lever over head at the
train operator's station. This shaft, positioned by a lever
and detent, provides adjustment for the clutch by means of an
adjustable coupling.
