2 Claims. (ci. zz-m)
This invention relates more particularly to the
construction and process of making molds for the
production of hollow glass ware, such as tumblers
- and similar vessels.'
Such molds are commonly made of cast iron in
portion 1 during the casting operation and hav
ing a chilling eiïect on said casting. Said chilling ,
ring 8 is designed to cooperate with the base 'I in
forming the external portion of the top of the
glass mold including its lugs 6“ and cooperates
one or more parts. In the production of «hollow
with said base in the chilling eilîect.
glass ware it is highly important that the matrix
or molding surface be very hard and susceptible
The base 1 and plug 'la are provided with a hole
8 axially in the plug, as shown in Fig. 1, said hole
being threaded at its lower and upper ends, as
shown at I0 `and ~II respectively. The lower 10
thread IIl receives a threaded nipple I2 suitably

In the views 6 designates a glass mold to be
produced, said glass mold being commonly of cast
iron containing alloyed therewith such: other
metal or metals as may be desirable and useful
in obtaining suitable hardness and texture. Said
mold is provided with lugs Iia threaded for attach
ment to its support in a machine. The larger
portion of the opening’in the mold is shown as
tapered internally to the external form of the
tumbler to be made and the opening at the
smaller end of the taper is to receive a valve-like
member (not shown) for forming the bottom of
the tumbler and dislodging the molded tumbler.

hole 8 at a regular or desired speed for ten or
twelve minutes o_r for such other period as to
chill the cast metal to the desired depth, say one
fourth of__ an inch or more of the glass mold body
and provide a deeply extended hard surface ca
pable'of receiving a high polish.
In the chilling operation the ring I8 cooperates
withithe plug 'I8L and base 1 in conducting heat 40
from the larger or heavier end of the casting
and thereby promoting evenness >of the chill»
throughout the inner or molding face of the glass
mold. It also may be noted that at the region
of said portion of the mold the entering water is 45
cool and becomes warmer as it passes upward
