PROVISIONAL SPECIFICATION.
A Combined Refuse Furnace and Gas Manufacturing Apparatus.
We, WALTER JOHN LOMAX and CHARLES JAMES LOMAX, both of 11 Fold
Street, Bolton in the County of Lancaster, Surveyors, do hereby declare the nature
of our said invention to be as follows:-
This invention relates to a combined refuse furnace and gas manufacturing
apparatus employed for making gas from cither coal, sewage sludge, excreta, or
other material or materials of a gaseous nature, and has for its object the disposal
of town refuse in a cheap and efficient manner. This we effect by constructing a
furnace under the ordinary retorts employed in gas manufacturing apparatus, and
provide the said furnace with means for charging the same with town refuse from a
hopper or its equivalent. Between the hopper or its equivalent and the refuse
furnace a drying chamber may be provided if desired or necessary. The furnace
can be fed with town refuse by hand or by mechanical means from the hopper or
its equivalent, or from the drying chamber. In this arrangement of our invention
the charging of the retorts employed in gas manufacturing apparatus is not
interfered with, as they can be supplied with cannel, coal, or other fuel in the
ordinary manner. This invention is so arranged that the furnace for receiving or
burning town refuse can be of any convenient form or shape, and may be provided
with any form of cremator or other chamber to produce a higher temperature with
any appliances employed in the manufacture of gas. In another modification we
combine any suitable chamber in connection with the before mentioned furnaces
whether employed for producing a higher temperature to supplement the refuse
furnace or furnaces or for destroying carcases or light articles, or any other chamber
may be employed where the waste heat from the furnaces is sufficiently high for the
manufacture of gas, the same being used in combination with any form of gas
manufacturing apparatus. The refuse furnace may be supplied with a steam jet
blast for the purpose of increasing the heat sufficiently to burn any kind of town
refuse.

We, WALTER JOHN LOMAX and CHARLES JAMES LOMAX, both of 11 Fold
Street, Bolton in the County of Lancaster, Surveyors, do hereby declare the nature
of our said invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-

DESCRIPTION OF DRAWINGS.
Fig. 1 is a sectional elevation of our combined refuse furnace and gas manu-
facturing apparatus.
Fig. 2 is a part front elevation through line A B and a part transverse sectional
elevation through line C D in Fig. 1, and
Fig. 3 is a part sectional plan through lines E, F and G, H.
In carrying out our invention we construct the furnace J under the retorts K
the latter being of the ordinary description employed in the manufacture of
illuminating gas. The furnace J consists of the movable fire-bars L, which are
operated backwards and forwards by the cams M and driving gear M¹ from any
convenient source. Immediately above and at the driving end of the movable fire-
bars L we fix the hopper N, which may be of the form shown in Fig. 1 to allow of
town refuse being tipped therein by means of a cart or other vehicle, or fed by
hand, or mechanically by an ordinary bucket or other elevator or creeper. The
bottom end of the hopper N is the full width of the furnace J to ensure of the refuse
to be treated being delivered over the entire width of the same. The fire-bars L
being movable and on the self-carrying principle the refuse deposited thereon from
the hopper N is automatically carried the full length of the furnace J, during which
the refuse is burned or reduced to a friable state, and delivered by the movements
of the fire-bars L through the hinged door O to the floor P at the back end of the
furnace J. The hopper front is provided with the opening Q to allow of town
refuse being stirred up or pushed forward on the bars L by a rake or its
equivalent.
For the purpose of facilitating or increasing the burning or consuming power of
the furnace J and provide heat sufficiently high in temperature to burn any kind of
town refuse we provide the steam jet blast R disposed under the fire-bars L. To
further increase the efficiency of the furnace J the air blast S may be provided,
being supplied from an ordinary fan, blower, or an air current caused by a jet of
steam.
The upper side of the furnace J is provided with the openings T to allow of
the heat and gases given off from the burning refuse being transferred into the
retort chamber V, where the gases will be consummed and the heat utilized for
assisting in maintaining or supplementing the temperature of the retorts K
employed for manufacturing gas from either coal, cannel, sewage sludge, excreta,
or other material or materials of a gaseous nature. The charging of the retorts K
may be effected in the usual manner by removing the lids W. If desired a
supplementary air supply X may be provided, the same being regulated by the
door or cover Y. Smoke and unconsumed gases pass from the retort chamber V
through the openings Z to the flue or flues leading to a stack or chimney.
We would have it understood that we do not confine ourselves to the exact
manner set forth in the drawings as the same may be varied or modified according
to the various kinds of gas manufacturing apparatus and refuse furnaces without
departing from the principle of our invention.

page_text: Having 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 combination with the retort chamber and retorts of gas manufacturing
apparatus the use of a furnace disposed below the same for burning town refuse,
substantially as described.
2. In gas manufacturing apparatus consisting of a retort chamber or chambers,
retorts, and a furnace or furnaces disposed below the same for burning town
refuse, the combination of a hopper or hoppers, and self-carrying fire-bars, with
or without steam jet blasts, substantially as described.
