Year: 1887

page_text: I, ALFRED RANGOD PECHINEY of Salindres (Gard) in the Republic of France,
Chemical Manufacturer, do hereby declare the nature of this invention to be as
follows:-
In the specification of a former Patent dated the 1st day of August 1885, No. 9225
was described an apparatus in which there was a movable regenerative burner
which could be placed in front of a series of furnaces so as to heat them successively
as required.
The present invention has for its object a modification in which the relative
movement of the two parts of the apparatus, namely, the furnace and the regenerative
burner is obtained by other arrangements without otherwise altering the invention.
For example the furnaces may be movable and be presented in turn before the
regenerative burner, which is fixed.
In this case I prefer to arrange the furnaces in pairs in front of each of the
regenerative burners. The two furnaces placed back to. back may be mounted on a
turntable so that one or other of them can at pleasure be brought in front of the
regenerative burner, whilst the other produces the decomposition of oxychloride of
magnesium or other product.
Or again, the arrangement may be inverted, that is to say, the two furnaces may
be arranged so that the regenerative burner placed between them can, by a
movement of rotation around a vertical axis, present itself to each of them alternately
to boat tham

page_text: It must be understood that the movement of the furnace in respect to the
regenerative burner or vice versa may be varied without in any way changing the
nature of my invention. Thus, I may employ either separately or in combination
the one with the other, movements of translation of rotation or a rocking motion.
Again in some cases it may be advantageous to substitute for heating by gas with a
regenerative burner heating by ordinary fire-places with grates and put in direct
communication with the furnaces.

I, ALFRED RANGOD PECHINEY, of Salindres (Gard) in the Republic of France,
Chemical Manufacturer, 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 :-
In the Specification of a former Patent dated the 1st day of August 1885, No. 9225,
was described an apparatus in which there was a movable regenerative burner which
could be placed in front of a series of furnaces so as to heat them successively as
required.
The present invention has for its object a modification in which the relative
movement of the two parts of the apparatus, namely, the furnace and the regenerative
burner is obtained by other arrangements without otherwise altering the invention.
For example the furnaces may be movable and be presented in turn before the
regenerative burner, which is fixed.
In this case I prefer to arrange the furnaces in pairs in front of each of the
regenerative burners. The two furnaces placed back to back may be mounted on a
turntable so that one or other of them can at pleasure be brought in front of the
regenerative burner, whilst the other produces the decomposition of oxychloride of
magnesium or other product.
Or again, the arrangement may be inverted, that is to say, the two furnaces may
be arranged so that the regenerative burner placed between them can, by a
movement of rotation around a vertical axis, present itself to each of them alternately
to heat them.

page_text: into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section of an apparatus constructed according to this
invention.
The two furnaces A A are mounted back to back upon a platform B capable of
turning about a vertical axis B' and supported by rollers C. D is a regenerative
gas burner-it is mounted on wheels D' to enable it to be moved slightly away from
the furnace A to allow the covers to be put on the openings and the furnace A turned.
E and F are hinged covers for closing the openings into the furnace A; as shown
they can be turned out of the way to allow the burner to be brought into position-in
other respects the apparatus is similar to that forming the subject of my former
Patent, and needs no further description.
Figure 2 shows a vertical section of an apparatus similar to that last described
except that the regenerative gas burner is replaced by an ordinary fire-place G.
Figure 3 shows a vertical section of a modified apparatus-in this case the two
furnaces A are placed at a distance apart and face each other; between them is the
regenerative gas burner D-as before, this is mounted upon wheels D' running upon
rails when the furnace A on the left has been sufficiently heated the burner Dis
removed from it on to the turn-table H; it there is turned through half a revolution
and is brought to the other furnace A on the right, which is heated, whilst the
decomposition of the oxychloride or other material is taking place in the furnace A
on the left.
Figure 4 is a vertical section of an apparatus which is similar to that shown in
Figure 3 except that the regenerative gas burner is replaced by an ordinary
fire-place.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be perforined I declare that what I claim is :-
1. The apparatus substantially as described and shown in Figure 1.
2. The apparatus substantially as described and shown in Figure 2.
3. The apparatus substantially as described and shown in Figure 3.
4. The apparatus substantially as described and shown in Figure 4.
Dated this 6th day of September 1888.
