carries the coal from, the pit into
silo which has a capacity of
100 tons; the coal in, the silo is
then fed into the automatic stok-
ers and thus into the fire box.
The smoke stack is 100 feet
high and is So inches in diameter.
The air compressors furnish
the air that is required in var
ious production operations.
Machining Area
The production equipment on
the right is known as the Bush
ing Line and that on the left is
the Washer Line. On the far left
you will notice a very extensive
Tool Crib in which are stored all
the. tools, dies, and supplies to
operate the machining and main
tenanee sections of the plant. It
is not only extensive but also
contains wealth of equipment.
Bushings ss-. e..
The problem of forming Bush
ings in the section on the right
arise from very exact specifica-
tions demanded by our custom
ers. The outside dimension of the
bushing, as it is cylindrical, must
be exact, almost perfectly round
and free of scratches, The sharp
edge of the end of the bushing
must be tapefed off sufficiently
to permit the starting of the
bushing into the metal hole
where it will finally be inserted.
Sometimes the dimensional re-
luirements for the outside di-
mensions are so exact, or the fin
ish required is so perfect, that it
must be put on with a grinding
process which produces better
and closer finishes than we can
obtain with punch presses and
lcutting tools.
The required finishes on the
inside of the bushings also vary
in many ways depending upon
the use to which the individual
bushings are to be put. In some
instances, we ship bushings to
the customer with rather rough
appearing inside finish. This can
be the case where the inside of
the bushings are finished in the
customers shop when the bush
ings are being assembled in a
particular product.
All of the machines you see
contribute in some way to meet
the requirements of the product
and the quality which our Gus
toners demand.
The various grooves and inden-
tations you will notice on the
surface of washers and bushingS
are there to provide for the lub-
rication of the bushing or wash
er when they are installed in the
application they were designed
for.
Washers
On the left we have our other
type of product-Washers. There
are hundreds of different sizes
and shapes of washers and they
are used in a very wide variety
of mechanical devices. Many of
the dimensions must be very
closely held and the matter of
the location of each hole and
projection and notch is very ex-
act. You probably have never
seen anything quite so perfectly
flat as these washers many
washers are hit in the large SOC
ton press which you see to insure
flatness. If some of them have a
warp or bend of so much as .005
of an inch, it will cause them to
be not acceptable to our custom
ers and thus make scrap of them.
AS you are all probably aware,
some of these very simple look
ing operations, all have defin-
ite purpose in keeping the pro-
duct within required limits.
Washers are inserted in some
position in a mechanical device
to prevent excessive use and
wear. We commonly know them
as thrust washers because they
are basically to protect against
some thrusting motion of the
shafts involved in the applica-
tions they are installed in.
All in all, approximately $4,000
different parts will be manufac-
tured in this plant in the course
of one year.
1t is on the type of products
you have seen that The Cleve-
land Graphite Bronze Company
has grown from a very small
company in a little plant, en-
ploying twenty 800 people, to a
Company employing nearly 5000
people working in fifteen (l5)
