PROVISIONAL SPECIFICATION.
Improvements in the Construction of Shoots for Charging Inclined
Gas Retorts.
We, LUDOVIC VAN VESTRAUT, Civil Engineer, and MAURICE GRAHAM,
Engineer, both of 86 and 884 Leadenhall Street, E.C. in the County of London,
do hereby declare the nature of this invention to be as follows :-
Our invention relates to improvements in the construction of shoots for charging
inclined gas retorts, when inclined from the horizontal line, which consists of a
shoot having a number of flaps at the proper respective heights at the back of the
shoot, which can be swung into position inside shoot at any moment. The shoot
is preferably square in section.
This invention is constructed with a movable and adjustable shoot of the requisite
length to communicate with the coal supply and the mouths of the retorts, and at
the level of said mouths is movable diaphragms or stops (shaped to form the
requisite angle with the vertical line and the floor of retort), can be put across
the channel of shoot so that all material falling to that point is deviated from the
vertical line and slide onto a slide which makes communication with the floor of
retort and the said diaphragms, and thus the coals are slid into mouth of retort;
the slides and diaphragms are withdrawn and allow the shoot to be used in a similar
manner for the next row of retorts. These said diaphragms and slides to be fixed
at any required level suitable to the heights of retort mouthpieces.
At the back of the shoot we place the diaphragms fixed to shoot loosely so that
the said diaphragms may slide easily in to position on guides. Falling flaps are
provided in front of the shoot to lap under diaphragms at back end or in any other
suitable position. The said shoot may be charged by means of a movable hopper
or other suitable means.
It will be understood that the foregoing is given by way of illustration only and,
hat the shapes, materials and proportions of the various parts may be varied in
many ways within the scope of our invention.

Improvements in the Construction of Shoots for Charging Inclined
Gas Retorts.
We, LUDOVIC VAN VESTRAUT, Civil Engineer, and MAURICE GRAHAM,
Engineer, both of 86 and 88* Leadenhall Street, E.C. in the County of London,
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 :—
Our invention relates to improvements in the construction of shoots for charging
inclined gas retorts, when inclined from the horizontal line, and consists of a shoot
having a number of flaps at the respective heights at the back of the shoot which
can be swung into position, inside shoot at any moment.
This invention is constructed with a movable and adjustable shoot of the
requisite length to communicate with the coal supply and the mouthpieces of the
etorts, and at the level of said mouths are movable diaphragms, or stops (shaped
[Price 8d.]

page_text: to form the requisite angle with the vertical line, and the floor of the retort),
which can be put across the channel of shoot, so that all material falling to that
point is deviated from the vertical line and slid into a slide, which makes commu-
nication with the floor of retort, and the said diaphragms, and thus the coals are
slid into mouth of retort, the slides and diaphragms are then withdrawn, and allow
the shoot to be used in a similar manner for the next row of retorts. These said
diaphragms and slides to be fixed at any required level suitable to the heights of
retort mouthpieces.
At the back of the shoot we place the diaphragms fixed to shoot loosely, so that
the said diaphragms may slide easily in to position. Falling flaps are provided
in front of the shoot, to lap under diaphragms at the back end, or in any other
suitable position. The said shoot may be charged by means of a movable hopper,
or other suitable means.
We attain these objects by the mechanism illustrated in the accompanying
drawings, in which-
Figure 1 is a front view of Fig. 2, shewing the movable trough to connect the
shoot with retort, this figure is broken off';
Fig. 2, is a vertical section of the shoot with movable troughs and diaphragms;
Fig. 3, is a vertical section of a part of a shoot with curved diaphragms;
Fig. 4, is a vertical section of a shoot with measuring chambers;
Fig. 5, is a front view of movable slide;
Fig. 6, is a vertical section of a shoot with movable slides;
Fig. 7, is a section on line A. B;
Fig. 8, is a front view of door of measuring chamber of Fig. 6;
Fig. 9, is a front elevation (partially described,) of Fig. 10;
Fig. 10, is a vertical section of a shoot to feed retorts on each side.
Similar letters refer to similar parts throughout the views.
In Figs. 1, and 2, we construct the shoot b with a receiver a, and near the said
receiver we attach a frame with wheels g, g, to travel on rails j, j. In various
positions we hinge movable diaphragms e, e, with stays f which are notched so that
the diaphragms may be adjusted to the desired position. In the front of the
shoot we attach movable troughs d, d, d, working on centres, with a door c to
regulate the flow of charging material. This shoot may be carried below by
wheels on horizontal rails i, i.
If preferable we construct a shoot with curved diaphragms e, e, as in Fig. 3.
It will be seen by Fig. 4, that the shoot bis applicable to a movable diaphragm e
operated by a lever k, and a measuring chamber with door c, and slide or con-
nection n placed opposite the mouth of retort m. The measuring chambers 1, 1, 1,
is mounted on a frame o and carried on wheels.
To the shoot and at each measuring chamber we fix a sliding diaphragm e
working between angle irons p, and mounted on a frame as in Figs. 5, and 6. To
each measuring chamber we hinge a door c with a lever f' which secures the
door e by the saw cut notches on the catch f2. When the measuring chamber is
charged with material and placed near the mouth of the retort the door c is opened
by releasing the lever f¹ from the catch f³.
In Figs. 9, and 10, we describe the shoot with a row of measuring chambers
on each side of the shoot, each heing operated in a similar manner as herein before
described. It is possible we may prefer to construct a covert with hinges ",", r
to either or all of the measuring chambers. The dotted lines indicate the levers k
of the diaphragms e and the catch r. Beneath the diaphragms e we fix an angle
plate in order to support the diaphragm e opposite or vice versu as described in
Fig. 10. This shoot can be carried on wheels g above, or below on wheels, or if
preferred by a pivot a' in a socket a² as shown by dotted lines.
It will be understood, that the shoot may be constructed of any suitable section;
and that the shapes and proportions of the various parts may be varied in many
ways within the scope of our invention.

page_text: now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is;-
1. In a shoot for charging inclined gas retorts, the combination of the receiver a
shoot and wheels jor h to run on rails i or, with the movable troughs d, and
diaphragms e straight or curved and the adjustable stays and doors c, sub-
stantially as herein described and according to Figs. 1, 2, and 3, of the accom-
panying drawings.
2. In a shoot for charging inclined gas retorts, the combination of the shoot,
diaphragms and levers, with measuring chambers doors and connecting pieces,
substantially as herein described and according to Fig. 4, of the accompanying
drawings.
3. In a shoot for charging inclined gas retorts, the combination of the shoot
movable diaphragms angle irons and measuring chambers with doors and levers
with catches, substantially as herein described and according to Figs. 5, 6, 7, and 8,
of the accompanying drawings.
4. In a shoot for charging inclined gas retorts, the combination of the shoot
movable diaphragms and levers with a double row of measuring chambers doors
and levers, to work on a pivot in a socket, or to be carried on wheels above
or below, substantially as herein described and according to the accompanying
drawings Figs. 9, and 10.
5. In a shoot for charging inclined gas retorts, the combination of the various
parts to be constructed of any size or shape, or with any modification of the parts,
substantially as herein described and for the purpose set forth.
