"IMPROVEMENTS IN APPARATUS FOR AND MODE OF MANUFACTURING MIRROR
WINDOW OR OTHER FORMS OF GLASS A communication to me from Monsieur le
Baron Ferdinand del Marmol residing at Bruxelles, Belgium.
"
The present invention has for its object an apparatus and process for the
production direct of mirrors, window glass, and other articles of polished glass, by
the aid of a new system of melting.
The apparatus consists of the following parts:-
1. A casing provided with a cover closing hermetically, in case the liquid should
be worked without pressure. This cover is provided with a ring used to turn it
about the hinge or allow it to run in the grooves; it is made with a rim in order
to have a better closure.
2nd Two vertical horizontal or inclined walls, fixed or movable, of any desired form
having in their bottoms or sides an aperture or passage which can be closed by any
convenient means. This aperture or passage can if desirable be provided with
slides fixed or movable and with fixed or movable bars which can be left out, as
well as the grooves if desired.
3rd. A movable plug regulating the flow of liquid; this is optional.
4th. If desired the interior of the apparatus can be furnished with tubes placed
across or through both sides and ends in such manner as to obtain a heat as strong

page_text: and as regular as the work requires; they serve for the introduction and exit of
air and gas, as well as the production of the desired pressure.
In the interior of the apparatus and behind the walls, flues are placed provided
with gratings in case the apparatus should be warmed by means of a solid com-
bustible. Working in grooves is a movable slide used as an obturator, to regulate
the aperture of the orifice of evacuation or exit.
The interior of the apparatus can be lined with bricks and the casing replaced
entirely or partly, by masonry or other material suitable, strong enough to stand
in case of pressure. Small conduits can be arranged below the bars for the flow of
glass which leaks through the joints of the same.
The apparatus is carried on abutments. resting on supporting walls or any
suitable material.
Lastly a carriage which can be placed under the apparatus fixed or movable to
receive the discharged glass.
The form and the dimensions of the apparatus are variable and determined by
the kind of work to be performed.
The melted glass is poured into the apparatus, whence it flows into the form
which is desired to be obtained, whether naturally or under pressure, or between
two smooth or fluted cylinders; the method of pouring out and cooling should be
according to the kind of manufacture.
The apparatus is heated internally, externally or both by gas or coal. From the
apparatus the hot glass runs out by an aperture, and is collected to be worked
according to requirements, and gradually cooled in the ordinary manner.
The upper part of the apparatus can be closed or not with the aid of the cover
depending upon whether pressure be used to drive the glass into the apparatus.
Naturally the flow of glass can be continual or intermittent according to the kind
of work to be effected and the dimensions of the pieces to be obtained.
1
By means of the apparatus in the process described glass objects may, the com-
munication states, be economically produced suppressing completely or almost
completely the apparatuses for annealing, soaping, polishing or blowing which are
at the present time used in these manufactures.

WILLIAM PHILLIPS THOMPSON, of the firm of W. P. Thompson and Boult, Agents
for Foreign Patent Solicitors, 6, Lord Street, Liverpool in the County of Lancaster
"IMPROVEMENTS IN APPARATUS FOR AND MODE OF MANUFACTURING MIRROR,
WINDOW, OR OTHER FORMS OF GLASS."-A communication from Monsieur le Baron
Ferdinand del Marmol, residing at Bruxelles, Belgium.
The present invention has for its object an apparatus and process for the
production direct of mirrors, window glass, and other articles of polished glass, by
the aid of a new system of melting.
In the accompanying Drawings, Fig. 1 represents a transverse section of the
apparatus, and Fig. 2 is a side elevation with one of the supporting walls
removed.
In these. E is a casing provided with a cover C closing hermetically, in case it
should be wished to conduct the melting under pressure. This cover is provided.
with a ring A, used to turn it about the hinge L or cause it to slide in grooves;
it is made with a rim B in order to obtain a better closure. P are two vertical
horizontal or inclined walls, fixed or movable, of any desired form, and having in
their bottoms ör sides an aperture or passage O which can be closed by any
convenient means. This aperture or passage O can (though they are not
indispensable) be provided with slides or grooves K fixed or movable, and with
fixed or movable bars which may, as well as the slides, be left out if desired. Mis
a movable plug regulating the flow of liquid; this is optional.
If desired, the interior of the apparatus can be furnished with tubes G placed
through both sides and ends in such manner as to obtain a heat as strong and as
regular as the work requires; they serve for the introduction and exit of air and
gas, as well as for producing the desired pressure.
In the interior of the apparatus and behind the walls P, flues Y are placed,
provided with gratings I, in case it should be wished to warm the apparatus by
means of a solid combustible. A movable slide T used as an obturator can also be
arranged in the grooves K, to regulate the aperture of the orifice of evacuation
or exit.
.
The interior of the apparatus can be lined with bricks, and the casing E replaced,
in part or in whole, by masonry or other material which will serve to support the
apparatus in case of pressure. Small conduits Z can be made in the bottom of the
walls for running off any glass which may have leaked through the joints of these
latter.
The apparatus may carry shoulders or abutments S (resting on supports Q) of
any suitable material.
Lastly a carriage N fixed or movable may be arranged under the apparatus for
receiving the run-out glass.
The form and dimensions of the apparatus are variable and determined by the
kind of work to be performed.
The melted glass is poured into the apparatus, whence it flows into the form
which is desired to be obtained, either naturally or under pressure, or between two
smooth or fluted cylinders; the method of pouring out and cooling should be
appropriate to the kind of manufacture.
The apparatus is heated in any suitable manner, either internally, externally, or
both, by gas or coal. From the apparatus the hot glass runs out through the

page_text: aperture and is collected to be worked according to requirements and gradually
cooled as in the ordinary processes.
The upper part of the apparatus can be closed or not with the aid of the cover C,
depending on whether or not pressure is used to expel the liquid glass. Naturally
the flow of glass can be continuous or intermittent, according to the kind of work
to be performed and the dimensions of the pieces to be obtained.
"
By means of the apparatus and process described, glass objects may, the com-
munication states, be economically produced, suppressing completely or almost
completely the apparatus for annealing, soaping, polishing, or blowing, which are
at the present time used in these manufactures.
.
Having thus described the invention, translated from the description communi-
cated to me in French by my foreign correspondent, I wish it to be understood
that what I claim is:
1st. The apparatus, substantially as described, serving to receive the melted
glass coming from crucibles for distribution afterwards, with or without pressure,
upon a slide or other object designed to give to it, and preserve it in, the desired
shape.
i
2nd. In the apparatus described, the arrangement of vertical, horizontal, or
inclined walls P fixed or movable, serving to conduct the liquid glass towards the
aperture O, in combination with the flues Y, the gratings I and the tubes G,
substantially as described and for the purposes indicated.
3rd. The arrangement of an exit aperture O for the glass, whether this aperture.
is formed by means of movable or fixed slides and rods, or whether it is formed by
the walls themselves.
4th. The process of manufacture, which consists in receiving into a special
apparatus, heated or not, the glass coming from crucibles, for distribution after-
wards as has been described, continuously or intermittently, and which permits of
suppressing completely or partially the apparatus for annealing, soaping, polishing
and blowing.
In witness whereof I the said William Phillips Thompson have hereunto set my
hand and seal this thirty first day of December in the year of our Lord one
thousand eight hundred and eighty three.
