Improvements in Gas Furnaces for use in Glass and other Works.
1, RENÉ JULIEN MARIE REGNAULT of 126 Route de la Révolte St. Denis (Seine)
in the Republic of France, Furnace Builder, 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 :-
Hitherto gas furnaces employed in glass works have been furnished with two distinct
gas producers so as to be provided in a continuous manner with the gas which was
necessary for them, these two gas producers being cleaned out and charged
successively.
These furnaces were therefore provided with two distinct grates generally inclined
on the vertical axis of the furnace and arranged symmetrically on each side of this
axis.
This arrangement of furnace had for its principal inconvenience the necessity for
giving to the furnaces large dimensions, thus involving great cost of installation and
occupation of considerable space.
To obviate this inconvenience I have devised an arrangement of gas furnace with a
single grate but of such dimensions that there can be easily arranged above it two or
more feeding holes and that one half of the grate can be charged without in
impeding the proper working of the other half which will continue to work during
this time as gas producer.
any way
This arrangement which is equivalent to the juxtaposition of the two gas producers
which in existing furnaces are placed at a certain distance from each other, enables the
general dimensions of the furnace to be very considerably reduced and consequently
the cost of construction. I would further remark that consequent on this arrangement,
I obtain a considerable economy of fuel for the samo quantity of gas produced.
In order that my invention may be more clearly understood I have represented an
example of it in the accompanying drawing.
In this drawing Figure 1 is a horizontal section of the four pillars supporting the
entire furnace.
Figure 2 is a front view of the furnace seen from the feeding holes.
Figure 3 is a vertical section of the furnace drawn on the lines A B of
Figures 1 and 2.
In all the figures like parts are indicated by similar letters of reference.
a is the grate, bare the grate bars, and c d are the two feeding holes.
These two feeding holes are separated one from the other by a vertical piece e resting
on the masonry of the furnace by means of a groove made in the inclined plane f
which causes the grate to communicate with the two feeding holes so that the half of
the grate which continues to work shall not be at all interrupted by the opening of the
feeding hole which corresponds with the other.
It will be well understood that 1 do not limit myself to the arrangement just
described and that other modifications may be applied to my system of gas furnace
with single grate which by experience I may judge necessary without altering in any
way the essential nature of my invention.
I specially reserve the right :-
First. To arrange the feeding holes in any convenient way or to unite them into
one large enough to serve easily and at will either the one or the other half of
the furnace.
Second. To effect the separation of the two feeding holes, or the division of a
single feeding hole into two distinct parts by means of any convenient arrangement.
Third. To appply my invention to any system of furnace whatever may be their
nature, dimensions and use and particularly to pot furnaces, covered or uncovered,
reverberatory and other furnaces employed in glass works and other industries.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be employed I declare that what I
claim is :-
1. A gas furnace with a single inclined grate combined with two or several feeding
holes sufficiently large to permit of effecting the charging and clearing out of the
surfaces of the grate independently of each other substantially as herein described.
2. The arrangement of furnace with a single grate a. b. two feeding holes c. d
separated by a division e and an inclined plane fall substantially as herein shown and
described and for the purpose stated.
