 Cast iron
trivets are a convenient means of setting up instruments
on surface plates, machine tables, the floor, or any
place where the line of sight is close to the supporting
surface. The mounting ring has a
standard 3 1/2 inch - 8 instrument thread. Adapters
provide a means of attaching accessory slides, lifts and

| 237 Stand
|
 The 237 is ideal
for general shop applications and assembly areas. Its
flexibility and mobility allow very low alignment and
leveling operations as well as a complete range up to a
average surface plate heights. The stand closes seven
inches from the floor and travels to a height of 37
inches, as measured from the floor to the bottom plate of
the instrument. A 31-inch lateral shift occurs due to the
parallelogram design.

rigidity with minimum weight
- Instrment Mount: Standard 3 1/2 inch - 8 thread.
Internally threaded to accept the 800 precision
lift.

Stand
Construction
Base
Bases are cast iron for strength and stability. Three
two-inch casters with rubber tires are used for mobility
and retracted into the base by a foot pedal. (Due to its
weight and size, the model 232 stand has larger casters,
and raising or lowering them is accomplished by a hand
wheel on the base.) In use, the stand rests on three
adjusting screws with lock nuts. This permits leveling
the stand on uneven surfaces.
Main Tube
Main tubes are seamless steel tubing with a clamping
collar on the upper end. Air trapped inside this tube by
the air-check mechanism prevents rapid descent of the
instrument if both the ratchet and clamping level are
released at the same time.
Intermediate Tube
Intermediate tubes are hard chrome-plated for wear and
rust resistance. A great rack is attached for raising and
lowering the instrument. Interchangable instrument mounts
screw into a 2.825 - 20 NS-2 thread at the upper end of
this tube. The aircheck mechanism is attached at the
lower end of the tube.
Controls
Raising and lowering of the instrument mount is
controlled by means of a capstan with pinion gear,
ratchet and clamping lever. These are chrome-plated. The
capstan spokes and clamping level have black phenolic
knobs.
