PROVISIONAL SPECIFICATION.
Improvements in and relating to the Measuring and Delivering of
Molten Glass or other Material, and Means therefor.
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:-
--
This invention is intended to provide means for measuring off from a glass pot
or other receptacle, definite quantities of molten glass and the means hereinafter
described are especially intended for this purpose, though suitable also in general
for measuring off quantities of viscid or semi-fluid materials in a state of heat or
otherwise.
The improved means comprise a valve or gate which is movable vertically or
otherwise against the side of the pot or the like having a suitable orifice; a distance
piece or fixed covered channel from said valve or gate having one end concave,
and a rotary drum of cast iron or other suitable metal adjusted to the concave face
of the distance piece.
The valve may have a cast iron casing and be lined with fire brick or any
material that will resist the action of the molten glass or other material. A hole
or passage is carried through the valve or gate in line with the hole in the melting
pot; this passage or channel is also carried through the distance piece to the
drum. The valve is moved through a shaft and lever or any other suitable
means. The distance piece is supported by a frame which also acts as a guide to
the valve; it has an inner lining of firebrick and an annular space for water to
keep the metallic parts cool, especially those that come in contact with the glass.
The drum has a series of pockets of known capacities; these pockets may be
bored or drilled out of the solid drum, or the drum may have larger recesses in
which to fix removable pockets, so that one drum may do for several sizes or
quantities of glass. The shaft which carries the drum is supported on brackets
with adjusting arrangements so that if necessary the drum may be drawn back and
changed, or the distance piece may be lifted out. The shaft may be revolved by
hand or any other motive power.

Improvements in and relating to the Measuring and Delivering of
Molten Glass or other Material, and Means therefor.
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 :—
This invention is intended to provide means for measuring off from a glass pot or

page_text: other receptacle, definite quantities of molten glass and the means hereinafter
described are especially intended for this purpose, though suitable also in general
for measuring off quantities of viscid or semi fluid materials in a state of heat or
otherwise.
This invention.is illustrated in the annexed drawing in which Fig. 1 is a front
elevation of a glass pot with means for measuring and delivering the glass there-
from. Fig. 2 is a plan view and Fig. 3 a side elevation partly in section.
The improved means comprise a valve or gate D which is movable vertically or
otherwise against the side of the pot A. or the like having a suitable orifice Qa
distance piece C or fixed covered channel from said valve or gate having one end
concave and a rotary drum B of cast iron or other suitable metal' adjusted to the
concave face of the distance piece.
The valve may have a cast iron casing and be lined with fire brick R or any
material that will resist the action of the molten glass or other material. The
hole or passage Q which is carried through the valve or gate in line with the hole
in the melting pot is also carried through the distance piece to the drum. The
valve is moved through a shaft F and lever G or by any other suitable means.
The distance piece is supported by a frame E which also acts as a guide to the
valve, it has an inner lining of firebrick S and an annular space T for water to
keep the metallic parts cool especially those that come in contact with the glass.
The drum has a series of pockets P. of known capacities; these pockets may be
bored or drilled out of the solid drum or the drum may have larger recesses in
which to fix removable pockets so that one drum may do for several sizes or
quantities of glass. The bearing blocks J of the shaft H which carries the drum
are supported on brackets K. with adjusting screws L and guide rods M so that if
necessary the drum may be drawn back and changed, or the distance piece may
be lifted out. The shaft may be revolved by hand or any other motive power.
As the drum revolves it is easily seen that as each. pocket P comes opposite the
hole it will be filled and will keep full until it has revolved below the concave
part of the distance piece, when it will be delivered. As each pocket during one
process will be the same size the quantity delivered will be equal in all cases.
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 :-
1. The device for measuring off and delivering molten glass or other material
comprising a valve fitted to the pot A, a distance piece beyond said valve and a
rotary drum having in its periphery pockets for the purpose set forth.
2. The construction of the valve, distance piece and drum and the means for
their operation and adjustment substantially as described and illustrated.
