We RICHARD CUNLIFFE, Agent of 89 Hankinson Street, Pendleton and JAMES
LUND, Traveller of St. Annes-on-the-Sea, 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 calcining, drying, or
roasting substances or materials and extracting gases or acids therefrom, and has for
its object to perform these operations with perfect uniformity, speedily and self-
actingly and to prevent explosions.
The invention consists principally in the employment of a rotating bottle shaped
vessel or receptacle carried by a frame mounted on a carriage, and heated by coal or
gas, above a furnace, inside a chamber.
This rotary bottle shaped vessel or receptacle is provided at its bottom end with a
trunnion, by means of which and the employment of two anti-friction rollers, the
said bottle shaped vessel or receptacle is carried and permitted to be rotated on the
said frame.
The latter is formed or provided with two trunnions and mounted upon a carriage.
One of the said trunnions is furnished with a worm wheel which gears into a worm
fixed on a shaft mounted on the side of the said carriage.
The shaft is provided with a handle by means of which any desired degree of
inclination can be given to the rotary bottle shaped vessel or receptacle, for the
purpose of facilitating the filling and emptying of the same, and constant turning
over of the material or substance to be treated.
The rotation of the latter is caused by means of a worm and worm wheel, the worm.

or
We RICHARD CUNLIFFE, Engineer, of 89 Hankinson Street Pendleton, and JAMES
LUND, Traveller, of St. Annes-on-the-Sea, 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 calcining, drying, or
roasting substances or materials and extracting gases or acids therefrom, and has for
its object to perform these operations with perfect uniformity, speedily and self-
actingly, and to prevent explosions.
And in order that our invention may be better 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 a side elevation and Fig. 2 an end elevation of our improved apparatus.
In carrying out our invention we employ a rotating bottle-shaped vessel retort or
receptacle a carried by a frame b, mounted on a carriage d, and heated by coal, gas
or oil, above a furnace e inside a chamber f.
This rotary bottle shaped vessel retort or receptacle is provided at its bottom end
with a trunnion g by means of which and the employment of two anti-friction
rollers h, working in grooves ¹ formed near the neck, the said bottle shaped vessel,
retort, or receptacle a is carried and permitted to be rotated on the said frame b.
The latter is formed or provided with two trunnions h² and mounted on the
carriage d.
One of the said trunnions is furnished with a worm wheel i, which gears into a
worm k, fixed on a shaft l, mounted in bearings m on the side of the said
carriage d.
The shaft is provided with a handle n, by means of which any desired degree of
inclination can be given to the rotary bottle-shaped vessel retort or receptacle a, for
the purpose of facilitating the filling and emptying of the same, and constant turning
over of the material or substance to be treated.
The rotation of the latter is caused by means of a worm o and worm wheel p, the
worm wheel p being fixed on the neck of the bottle-shaped vessel, retort or
receptacle a and the worm o fixed on the shaft 7, rotated suitably from a driving
shaft r.
The mouth of the bottle-shaped vessel retort or receptacle is closed by means of a
lids which is removed when the bottle shaped vessel retort or receptacle a is to be
filled or emptied.

page_text: For the purpose of carrying away and afterwards collecting by condensation
the extracted gases or acids, the lids is provided with a pipe t having a tap or
valve u.
The carriage d carrying the rotating bottle-shaped vessel retort or receptacle a is
arranged to be run on rails v, in and out of the chamber f fixed or built over the
furnace e.
In order to thoroughly turn over the material or substance to be treated I provide
a portion of the interior of the rotating bottle-shaped vessel retort or receptacle a,
with inclined plates w, or other suitable means which will prevent the caking of the
material or substance, and ensure a uniform treatment of the same.
When the rotating bottle-shaped vessel or receptacle a is to be filled or emptied, its
mouth is caused to incline downwards by means of the worm and wheel o & p, and
when the substance or material is under treatment, upwards, so as to prevent the
running of the same into the neck of the said vessel retort or receptacle a and
enabling the gases to separate and freely escape through the pipe t.
The advantages derived from the peculiar shape of the vessel retort or receptacle a
and rotation of the same in an inclined position, are, those of keeping back from the
outlet of the vessel retort or receptacle a, and of constantly throwing back and
consequent thorough agitation of the material under treatment, while the gases get
separated from the latter and are permitted to escape readily through the pipe t.
We may remark that the section or design of the rotary vessel retort or receptacle a
may be altered without departing from the nature of its functions.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed we declare that what we claim is :-
1st. The general arrangement and combination of parts constituting our
improvements, for the purpose and substantially in the manner hereinbefore
described.
2nd. The formation of the vessel retort or receptacle a and rotation of the same in
an inclined position, substantially as and for the purpose specified.
3rd. The manner of separating and collecting the gases from the substance or
material under treatment.
4th. The combination of the vessel retort or receptacle a with a frame b and
carriage d and mode of operating the same, as set forth.
