PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Drying, Calcining, and Evaporating
Substances or Materials such as Town's Refuse, Brewer's Refuse
and Grains, Spent Dye Wood, and the like.
We, EDWARD BARLOW, of 26 Fountain Street, Manchester, Smallware
Manufacturer, and RICHARD CUNLIFFE, of 168, Ellor Street, Pendleton,
Engineer, both in the County of Lancaster, do hereby declare the nature of this
invention to be as follows:-
--
Our invention relates to improvements in apparatus for drying, calcining and
evaporating substances or materials such as towns refuse, brewers refuse & grains,
spent dye wood, & the like and has for its object to make such apparatus more
simple and effective than heretofore has been the case.
This invention consists of a rotating retort or cylinder, made to rotate horizontally
on pulleys, partially enclosed in a cover or casing, the top part of which is lined
with non-conducting material to prevent loss of heat. Inside the retort or cylinder,
concentric therewith, we employ a perforated suction pipe, one end of which is in
communication with an exhaust fan for the purpose of carrying away and afterwards
collecting by condensation the extracted gases or acids. The said perforated
suction pipe is received and carried by the respective ends of the retort or cylinder,
one end of the latter is made removable in order to facilitate the placing of the
perforated suction pipe, the same is made in two parts correspondingly fitted into
each other and locked by suitable means. The removable end of the said retort or
cylinder is provided with two openings for the purpose of charging and discharging
the said retort or cylinder, each opening being closed by suitable doors or lids.
The said retort or cylinder is provided with a furnace or grate which is suitably
charged with gas, coke, or charcoal, etc.
In connection with the said retort or cylinder near the lower part thereof, we
employ another fan for the purpose of causing a draught and spreading the fire
uniformly over the surface of the said rotating retort or cylinder, which is
continuously retoted by means of a worm in gear with a worm wheel fixed to the
exhaust end thereof.

Improvements in Apparatus for Drying, Calcining, and Evaporating
Substances or Materials such as Town's Refuse, Brewer's Refuse
and Grains, Spent Dye Wood, and the like.
We, EDWARD BARLOW, of 26 Fountain Street, Manchester, Smallware
Manufacturer, and RICHARD CUNLIFFE, of 168, Ellor Street, Pendleton, Engineer,
both in the County of Lancaster, 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 apparatus for drying, calcining and
evaporating substances or materials, such as town's refuse, brewer's refuse and
grains, spent dye wood, and the like, and has for its object to make such apparatus
more simple and effective than heretofore has been the case.

page_text: And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is partly a longitudinal section and partly a side elevation.
Fig. 2 is a cross section on line A-B of Fig. 1, and
Fig. 3 an end view of our improved apparatus.
Fig. 4 is also an end view showing a modification thereof.
In carrying out our invention, the improvements consist of a rotating retort or
cylinder u, formed at each end with an angle iron ring a' adapted to rotate
horizontally on pulleys b. The said retort or cylinder a is partially enclosed in a
cover or casing c, the top part of which is lined with non-conducting material c¹ to
prevent loss of heat. Between the casing and the retort or cylinder a, a space
is formed, into which the hot gases from the furnace rise for the purpose of being
absorbed by the retort or cylinder a, a chimney being also provided in connection
therewith for the escape of the smoke. Inside the retort or cylinder a, which we
form with agitator blades a², we employ concentrically therewith, a perforated
suction pipe, one end of which is brought in communication with an exhaust fane,
preferably such as shown in the drawings, for the purpose of carrying away and
afterwards suitably collecting by condensation the extracted gases or acids. The
said perforated suction pipe d is carried by the respective ends of the retort or
cylinder a, the end a³ of the latter being made removable, by means of suitable
bolts, in order to facilitate the placing of the perforated suction pipe d, which is
made in two corresponding parts fitted into each other and if deemed necessary
locked together by suitable means, such as bolts. The removable end as of the
said retort or cylinder a is provided with two openings g, for the purpose of charging
and discharging the retort or cylinder a, each opening being closed by a door or
lid hinged or otherwise fixed thereto.
In lieu of forming two openings g and doors as described, the removable end a³
of the retort or cylinder a, when the latter is made comparatively long, may be
formed with an opening and door extending across the whole diameter thereof,
see Fig. 4, so as to permit of entering the retort or cylinder a for the purpose of
charging or emptying it.
น
Below the retort or cylinder a is employed a furnace or grate h, preferably, such
as shown in the drawings, which may be charged with gas, coke, or charcoal in the
ordinary way, or with liquid fuel, as hereinafter described. One side of the
furnace we form with two doors i, & capable of being retained in position,
the door, covering the space above and the door i, that below the fire bars, which
facilitates the charging, inspection, and cleaning of the respective parts.
When using gas as a fuel the said fire bars receive or are substituted by suitable
burners, and when using liquid fuel are charged with asbestos or other incombustible
material onto which the liquid fuel is diffused by means of a steam or air blast jet k,
arranged in connection with the liquid fuel supply pipe k¹.
Immediately below the rotating retort or cylinder a we employ a slide or slides a',
by means of which communication between the furnace h and the exterior of the
rotating retort or cylinder a, can be cut off or established and thus the furnace heat
regulated to a nicety or cut off entirely.
In connection with the retort or cylinder a, namely the lower part of the furnace h,
we employ another fan e¹ having a pipe e communicating therewith for the purpose
of causing a draught and spreading the fire uniformly over the surface of the
rotating retort or cylinder a. The latter is continuously retoted by means of a
worm, fixed on a cross shaft l', suitably mounted and in gear with a worm wheel,
fixed to the exhaust end or pipe m of the retort or cylinder a..
In lieu of exhausting the hot gases from the retort or cylinder a by means of a
fan e, the same may be effected by means of a steam jet n, see Fig. 1, in connection
with a cone placed inside the exhaust pipe m, the cone n' serving to throttle the
gases while the steam jet forms a vacuum in front thereof, thus effectively exhausting
the same.

page_text: The forced draft for the furnace h may also be created by means of a steam jet o
placed inside the pipe e, as shown in Fig. 1, in lieu of the fan e¹.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is-
In apparatus for drying calcining and evaporating substances or materials, such
as town's refuse, brewer's refuse and grains, spent dye wood and the like.
1st. The general arrangement and combination of parts constituting our
improvements, operating in the manner substantially as and for the purpose set
forth.
2nd. A cylindrical retort a arranged to rotate on pulleys band with one end
removable, having a door or doors g', and the other end in communication with an
exhaust source, substantially as and for the purpose specified.
3rd. The cylindrical retort a specified in the preceding claim, provided internally
with a perforated suction pipe d, in communication with a fan e or other exhaust
source, substantially as and for the purpose specified.
