PROVISIONAL SPECIFICATION.
Improvements in Gas Retorts and in Apparatus connected therewith.
I, ANDRÉ COZE Managing Director of the Gas Company of Rheims, (Marne)
France, do hereby declare the nature of this invention to be as follows :-
My Invention relates to improvements in self-charging and discharging inclined
retorts of the kind described in the specification of former Letters Patent dated the
20th day of June 1885, No. 7563.
Reference is to be had to the accompanying drawings forming part of this specifi-
cation, wherein figure 1 represents details of the improved inclined retort hereinafter
described; Figure 2 is a vertical section of a bench of retorts, taken through one of
the rows of inclined retorts; Figure 3 is a vertical transverse section taken
respectively on lines 1-2, and 3-1, of figure 2; Figures 4, 5, 6 shew respectively
a side elevation, plan, and end elevation, of a tilting hopper truck specially designed
for use in charging the retorts.
The retort a (figures 1 and 2) which is made of such form in cross-section, as
will ensure a regular distribution of the coal, is contracted in depth and breadth at
its mouth ee where it passes through the brick-work setting and fits in the bend of
the charging mouth of which it forms a prolongation. The retort is also slightly
contracted at the discharging end. That part of the retort comprised between the
front and back walls of the oven is thus of larger cross-sectional area than its two
ends, by which means the disengagement of the gases is greatly facilitated while tho
coal by gravitating downwards towards the mouth of the shoot is distributed in a
regular manner throughout the length of the retort, all choking of the retort at the
upper end being prevented.
Figures 2 and 3 shew the improved method of constructing the charging mouths
or shoots.
These shoots are fitted, as shewn, over the mouth of the retort which
can thus terminate in a plane perpendicular to the axis of the retort. The advantage
of such an arrangement both in respect to the manufacture of the retort as well as
to the preservation of the joint will be evident if it be considered that in the
arrangement described in the previous patent referred to, the cast iron bend was
bolted to the flange of the retort which being inclined necessarily presented an
oblique angle. According to this improved arrangement, each bend is formed with a
rib or flange d, as shewn, forming a sole piece which is supported upon piers e in
the setting or otherwise so that all strain upon the joint is prevented and the joints
are consequently more easily made and kept in good condition. The charging mouths
as also the retorts themselves are suitably isolated from the setting in order to avoid
the effects of expansion and contraction.
Figures 4, 5, 6, shew an improved construction of truck each provided with several
tilting hoppers for charging the retorts. In the example shewn, the retorts are
disposed in rows of three in which case the trucks would have each three oscillating
hoppers corresponding to three charging mouths or shoots b in the same line. The
number of charging hoppers would thus be varied to suit the number of the
shoots.
Figure 4 shews in full lines the position of one of the charging hoppers when tilted
over the mouth of the shoot, while the dotted lines shew the hopper in the horizontal
position as when the trucks are in transit and also as tilted in the backward direction
for enabling the cover to be replace upon the mouth of the shoot. The hoppers are
supported by roller trunnions in slots and they are guided by pins engaged in guide
slots of such curvature in relation to the axis of rotation as to ensure the discharge
of the coal into the mouth of the shoot whatever may be the angle of discharge. The
mouth of the hopper is closed by an automatic shutter / pivoted at i and closing freely

of large lumps of coal and prevent their choking the passage into the retort. k is a
catch for holding the hopper in the horizontal position and a hand lever for tilting
it. It will be seen that the hopper, the shoot, and the inclined retort, together con-
stitute at the time of charging a continuous passage down which the coal passes by
its own gravity and is evenly and regularly distributed upon the inclined floor of the
retort without risk of obstruction at any point and under the same conditions for all
kinds of coal, thus always ensuring the free disengagement of the gases.

COMPLETE SPECIFICATION.
Improvements in Gas Retorts and in Apparatus connected therewith.
I, ANDRÉ COZE, Managing Director of the Gas Company of Rheims (Marne)
France, 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 :-
My Invention relates to improvements in self charging and discharging inclined
retorts of the kind described in the specification of former Letters Patent dated
the 20th day of June 1885, No. 7563.
The present invention comprises an improved form of retort and method of con-
necting the charging mouths or shoots to the retorts, together with an improved
construction of truck for charging the retorts.
Reference is to be had to the accompanying drawings, forming part of this specifi-
cation, wherein figure 1 represents details of the improved inclined retort hereinafter
described. Figure 2 is a vertical section of a bench of retorts, taken through one
of the rows or inclined retorts. Figure 3 is a vertical transverse section, taken
respectively on lines 1-2 and 3-1 of figure 2. Figures 4, 5, 6, shew respectively
a side elevation, plan, and end elevation, of the truck specially designed for use
in charging the retorts.
The retort a (figures 1 and 2) which is made of such form in cross-section as will
ensure a regular distribution of the coal, is contracted in depth and breadth at its
mouth ce where it passes through the brickwork setting and fits in the hend 6 of
the charging mouth of which it forms a prolongation. The retort is also slightly
contracted at the discharging end. That part of the retort comprised between the
front and back walls of the oven is thus of larger cross-sectional area than its two
ends, by which means the disengagement of the gases is greatly facilitated while the
coal by gravitating downwards towards the mouth of the shoot is distributed in a
regular manner throughout the length of the retort and choking of the retort at the
upper end is prevented.
Figures 2 and 3 shew the improved method of constructing the charging mouths
or shoots. These shoots are fitted, as shewn, over the mouth of the retort which can
thus terminate in a plane perpendicular to the axis of the retort. The advantage of
such an arrangement, both in respect to the manufacture of the retort as well
as to the preservation of the joint, will be evident if it be considered that in
the arrangement described in the previous patent referred to, the cast iron bend was
bolted to the flange of the retort which being inclined necessarily presented an
oblique angle. According to this improved arrangement, each bend is formed with
a rib or flange d, as shewn, forming a sole piece which is supported upon piers e in
the setting or otherwise, so that all strain upon the joint is prevented and the joints
are consequently more easily made and kept in good condition. The charging
mouth, as also the retorts themselves, are suitably isolated from the setting in order
to avoid the effects of expansion and contraction.

page_text: Figures 4, 5, 6, shew the improved construction of truck each provided with
several tilting hoppers for charging the retorts. In the example shewn, the retorts
are disposed in rows of three, in which case the trucks would each have three
oscillating hoppers f corresponding to the three charging mouths or shoots b in the
same line, but the number of charging hoppers would, of course, correspond to
the number of shoots.
Figure 4 shews, in full lines, the position of one of the charging hoppers when
tilted over the mouth of a shoot while the dotted lines shew the hopper in the
horizontal position as when the trucks are in transit and also as tilted in the backward
direction for enabling the cover to be replaced upon the mouth of the shoot. The
hoppers are supported by roller trunnions in slots and they are guided by pins
engaged in guide slots g of such curvature in relation to the axis of rotation as to
ensure the discharge of the coal into the mouth of the shoot whatever may be the
angle of discharge. The mouth of the hopper is closed by an automatic gate h
pivoted at and closing freely against the mouth of the hopper. This gate serves to
break the too-rapid descent of large lumps of coal and prevent their choking the
passage into the retort. is a catch for holding the hopper in the horizontal position,
and i a hand lever for tilting it. It will be seen that the hopper, the shoot, and
the inclined retort, together constitute at the time of charging a continuous passage
down which the coal passes by its own gravity and is evenly and regularly distributed
upon the inclined floor of the retort without risk of obstruction at any point and
under the same conditions for all kinds of coal, thus always ensuring the free
disengagement of the gases.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim as improvements in inclined gas-retorts is ;
1st. A retort of the kind herein referred to, in which that portion of the retort
comprised between the front and back walls of the furnace is of greater cross-
sectional area than the two ends and in which the bend of the charging mouth or
shoot is fitted upon the contracted mouth of the retort outside the setting, sub-
stantially as described and shewn for the purposes specified.
2nd. The improved construction of charging mouth or shoot fitting upon the end
of the retort and provided with a sole piece adapted to rest on a suitable support,
substantially as and for the purpose specified.
3rd. The construction of trucks for charging the retorts, with tilting hoppers each
provided with an automatic gate, substantially as and for the purpose specified.
4th. In gas-making apparatus of the kind herein referred to, the combination of
the retort, the charging mouth or shoot, and the tilting hopper, which together
constitute at the time of charging a continuous passage for the distribution of the
coal, substantially as described and illustrated in the drawings.
