Improvements in the Process of Manufacturing Moulded Glass.
I THOMAS EUNSON of 7 Aiskell Street, Sunderland in the County of Durham,
Glass-mould-maker do hereby declare the nature of this invention to be as
follows:-

According to this invention the glass is melted in a pot, run from the pot
directly to a measuring and delivering device, which operates automatically when
driven by suitable power, delivered as measured charges into buckets which are
carried by an endless belt or chain to a moulding press where the charges of
glass are formed into various articles, without any hand labour being necessary.
The measured quantities are delivered from the measuring machine into a
guide shoot and so into buckets on an endless chain or belt. These buckets may
be so spaced on the belt that each bucket is only filled once during two revolu-
tions of the belt, thus keeping the buckets cool. The buckets deliver into a shoot
which runs the glass directly into the mould. The buckets and shoots are lined
with a material or composition such as carbon, graphite, asbestos or the like that
will resist the heat and have no affinity for the molten glass. The measuring
device, if provided with the same number of pockets as there are moulds on the
press, must revolve at exactly the same rate, and the buckets must be so placed on
the belt that they come successively under the shoot at the proper time to receive
the charges of glass as they are delivered.
The belt which carries the buckets may be used as the driving belt to the press
which may be operated to present a series of moulds for successively receiving the
charges of glass.

Improvements in the Process of Manufacturing Moulded Glass.
I THOMAS EUNSON of 7 Aiskell Street, Sunderland in the County of Durham,
Glass Mould Maker do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
According to this invention the glass is melted in a pot, run from the pot directly
to a measuring and delivering device which operates automatically when driven by
suitable power, delivered as measured charges into buckets which are carried by
an endless belt or chain to a moulding press where the charges of glass are formed
into various articles without any hand labour being necessary.
The measured quantities are delivered from the measuring machine into a guide
shoot and so into buckets on an endless chain or belt. These buckets may be so

page_text: spaced on the belt that each bucket is only filled once during two revolutions of
the belt, thus keeping the buckets cool. The buckets deliver into a shoot which
runs the glass directly into the mould. The buckets and shoots are lined with a
material or composition such as carbon, graphite, plumbago, asbestos, or the like
that will resist the heat and have no affinity for the molten glass.
The measuring device if provided with the same number of pockets as there
are moulds on the press must revolve at exactly the same rate and the buckets
must be so placed on the belt that they come successively under the shoot at the
proper time to receive the charges of glass as they are delivered.
The belt or chain which carries the buckets may be used as the driving belt to
the press which may be operated to present a series of moulds for successively
receiving the charges of glass.
For the annexed drawing the means for carrying this process into effect are
illustrated in a diagrammatic manner.
Y is the pot in which the glass is melted, A is the revolving cylinder which
measures the glass and delivers it into the shoot R which may swing on the pin S.
L are the buckets carried on the chain belt K. Q is the shoot on the press,
which delivers the glass into the mould T on the revolving table U of the press..
Z is a belt sheave for chain or leather band driven from shafting or other motor.
H is the shaft carrying this sheave Z, also the wheels J and G. Motion is given to
the cylinder A by a chain belt on wheel G, working round a wheel Fon shaft E,
on which is a spur wheel D gearing into another spur wheel C. on shaft B which
carries the cylinder A. The belt K. is driven by the wheel J, thus driving
wheel N. Another belt from a wheel alongside N. and on same shaft transmits
motion to wheel P and thus drives the shaft X, which revolves the table U of the
press and works the plungers. The buckets may be made of sheet steel or any
other suitable material, and are lined with some fire resisting material, for which
the melted glass has no affinity. A lug L¹ projects at the back of each bucket
which will catch the shoot R to allow a little more time for the glass to fall into
the bucket. When the bucket has passed, the shoot falls again into its original
position. The top strand of chain K may be supported if necessary. In all cases
I use preferably chain belts. W is a bracket for supporting the wheel N and the
shoot Q. V is the casing of the press.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
The process of manufacturing moulded glass consisting in delivering measured
quantities of molten glass from the glass pot automatically, each successively or
alternately to one of a series of buckets carried by an endless belt, the said buckets
delivering their charges of glass successively into a shoot directing the charges
severally to a series of moulds automatically or otherwise brought beneath the
said shoot.
