How a Simplex Unit Pneumatic is
made. The starting point—three simple
blocks of selected maple.

I
T greatly reduces the number of parts. It is simpler to install
and regulate. It is much more easily accessible.
It gives greater responsiveness—greater freedom from
leakage.
Top and center blocks now joined and
machined by special automatic which
docs 8 operations.
The new Simplex Unit Pneumatic system eliminates about 33 per cent,
of the parts used in the old-style shelf construction. And with this simplifi-
cation comes vastly increased efficiency.
The pictures show a few of the processes through which a Simplex Unit
Pneumatic passes in course of its construction. Most of the operations are
performed by remarkable automatic machines contrived and put together
by Simplex engineers at the Simplex plant. This results, of course, in
saving on cost, plus uniformity of production, It is a very interesting
example of what can be done today in a modern manufacturing plant.
But pictures cannot show the really important thing—what the Simplex
Unit Pneumatic accomplishes for you.
A cloth hinge—put on by automatic
machine—now connects the free leaf of
the bellozvs.
