CHECKING MOLDS and
MAIN STANDS

All Monotype Molds, both new and repaired, are
guaranteed to be in good operating condition
when they leave our factory. They should be tested
promptly upon receipt by the customer and if
there is any complaint it should be made to the
Monotype Col, Philadelphia, immediately.

The printed instructions (see list on page 1) should be
followed for the care, maintenance, and operation of
Molds. Proper oil, in correct quantities, is essential for
satisfactory Mold operation. On page 3 is a list of oils
which long experience has proven to be satisfactory for
each type of Mold as indicated. We are prepared to
supply these oils to our customers.

The machines on which we test Molds are checked
frequently, not only for adjustments, but also for wear
— and particularly wear of the Main Stand where the
Mold is fastened on Composition Casting Machines and
Type-&-Rule Casters. In customers' plants this seat on
the Main Stand will, in time, become worn or damaged
by changing Molds, or rusted around the waterways, or
possibly warped slightly by the heat of casting. A Mold
placed on such a machine will not have a true bearing
for the three feet, and when the three Mold Screws are
tightened, the Base Plate of the Mold will be distorted,
and some or all of the Blocks on the Mold will be thrown
out of proper relation one with another. If a Mold is run
under such conditions, it may result in wear or damage
to the parts of the Mold and also in the casting of un-
satisfactory product.

If a Mold does- not operate satisfactorily, do not blame
the Mold until its seat on the Main Stand has been
checked. Each Monotype District Office is supplied with
a special Gage for this purpose. Get in touch with them.
Sometimes the Main Stand can be corrected in the cus-
tomer's plant. If badly worn, it may have to be returned
to our factory for regrinding. On very old machines
this condition, plus wear, may njake it advisable to ex-
change the machin^

PREPARING NEW OR REPAIRED
MOLDS FOR CASTING

To protect Molds from rust during shipment we are at
present using a light refined grade of grease which forms
a very thin film on the Mold, but gives perfect protec-
tion. Unless such Molds have remained in stock for a
considerable period of time it is not necessary to use any
kind of cleaning fluid for removing this grease. It is
sufficient to remove the Cross Block, wipe the grease
from it with a dry cloth and from the rest of the Mold
including the channel in which the Cross Block operates
and then thoroughly oil all parts of the Mold. If gaso-
line, benzine or any other cleaning fluid is used for re-
moving the grease it will de-grease any oil pads and
prevent oil getting through them for a considerable
period of time unless the oil pads are first removed and
then replaced after the cleaning is completed.

LUBRICATING OILS

Casting Machine Oil — For the general lubrication of
all Casting Machine parts and for all Molds which cast
type except Giant Caster Molds and Style 3U and 4U
Cored Molds.

Rule Mold Oil — For exclusive use on all Giant Caster
Molds and all Material Making Machine Molds; also
on Style 3U and 4U Cored Type Molds and all Lead-&-
Rule Molds.

Keyboard Oil — A special light-bodied oil for the lubri-
cation of all parts on Monotype Keyboards requiring
lubrication.

CAUTION: Not only the quality of the product, but
the very life of Monotype Molds and Monotype Ma-
chines depends on the use of the correct oil for each
purpose. We have spared neither time nor trouble in
finding the best and in maintaining a high standard of
each kind. The oil that we recommend and sell as "Rule
Mold Oil" is especially essential for the satisfactory
operation and preservation of all Material Making Ma-
chine Molds and Giant Caster Molds, also 3U and 4U
Cored Molds and all Lead-&-Rule Molds. We cannot
guarantee these Molds to operate satisfactorily if any

other oil is used.

WATER REGULATION

To prevent water leaks in Molds and produce the best
quality of product on Composition Casting Machines and
Type-&-Rule Casters regulate the water as follows: Open
wide the valve on the drain pipe. Slowly open the valve on
the supply pipe until the water flows with a full stream
from the drain pipe having the valve, but none from the
other drain pipe. Note how many turns or what part of a
turn the supply valve is opened and open it this amount
each time the water is to be turned on. Next, partly close
the valve in the drain pipe so that a portion of the stream
of water is forced up through the Mold and comes out the
other drain pipe. The amount of water to be thus by-passed
through the Mold is determined by the temperature of the
water coming out of this drain pipe from the Mold. This
water should be approximately 130 degrees in temperature.
The bulb of a thermometer placed in this stream of water
will give the temperature accurately. If no thermometer is
available, stick the finger in the stream of water which
should be so hot that the finger cannot be held in it.

Note : Old machines not equipped with globe type valves require
slight modification of above directions.

MOLD REPAIRS

Gate Pushers, Vent Pushers, and Caps for low leads and
slugs can usually be furnished without returning the Mold
if all pieces of the broken part are sent to us — for new Cap
send also its Support. Packing Pieces for Rule Molds are
furnished from stock.

It is not possible for operators to repair Molds because
they have neither the special tools nor the necessary
training.

If any defects occur in the type produced by this Mold,
that cannot be corrected by following the directions in our
Mold Folders, the Mold should be at once returned to us
with samples of defective type; enclose these in the box
with the Mold (also all extra Blades, Point Blocks, Mold-
blade Stops and Caps and Supports), prepay transportation
charges and write us stating (a) the style, point size, and
number of Mold; (b) date of shipment and route; (c)
IMPORTANT, on page 5 of this folder is a list of the more
common troubles due principally to wear. MARK an X
before each item of the list which gives trouble, as we will
check and test Molds particularly for the troubles marked.

Preserve Mold Box and Screws for returning Mold.
Do not nail the cover — tie it on.

ATTENTION OPERATORS

To insure getting the repairs you want tear off this page,
check items needing correction and send it to the Monotype
Co., Philadelphia, by First Class Mail (never with the mold
unless the mold is sent by Express).
