page_text: I CARL ERHARDT of 38 Brooke Street, Holborn in the City of London Merchant,
do hereby declare the nature of my said invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:-
The object of my invention is to manufacture an improved form and arrangement
of apparatus for roasting coffee, boiling water, and other analogous operations.
My invention consists of a metallic tray, surmounted with a trough containing
methylated spirit, or other suitable inflammable, material, and a suitable frame for
carrying a roasting cylinder.
And in order that my invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a perspective view of my invention, as arranged for roasting coffee.
Fig. 2 is a plan view, with the coffee cylinder removed.
Fig. 3 is a view of the underside of a moveable support for kettles, saucepans,
and such like articles.
Fig. 4 is a side view of the same in the position in which it is packed away
under the spirit trough, when out of use.
Fig. 5 is a plan view of an extinguisher, for putting out the flame.
Fig. 6 is a section of the same.
Fig. 7 is a plan view of a smaller extinguisher, for reducing the flame, when
required; and,
Fig. 8 is a sectional elevation, shewing the construction of the coffee cylinder.
a is the tray upon which the standards b b are fixed. c c are uncovered
bearings, in which the axles of the cylinder revolve. d d are air holes, passing
through the trought to convey air to the flame. e is a sliding door to the cylinder,
the edges of which enter grooves e¹ e¹. f is a handle attached to a crank, for
turning the cylinder, the handle being formed of non conducting material. g is
another handle, of similar material, attached to the axle h. The method of opening
..מ

page_text: and closing the sliding door e will be understood on reference to Fig. 8. The
The fixed
sliding axle h carries an arm i which unites the axle h with the door e.
axle is attached to the handle f, and also to the cylinder end l. This arrangement
enables the operator to open the door e, by means of the two handles, as shewn
in Fig. 8.
•
It is obvious that the position of the axles and sleeves or tubes may be varied to
produce the same result. By this arrangement the coffee can be inspected or
withdrawn, as desired, while hot, without burning the hands; the handles being
merely drawn apart, as shewn in Fig. 8.
.
The frame n may be placed over the trough, when the cylinder has been
removed;
the holes qq being provided for the reception of the pins rr; the
position being shewn by dotted lines in Fig. 2. This frame may sustain a kettle,
saucepan, frying pan, or other article over the flame of the spirit.
The extinguishers 8s have flanges 81 8¹ to keep them in position upon the trough.
The spout p is for pouring out the spirit, when no longer required.
The space between the tray and the trough is utilized to accommodate the
frame and extinguishers 8.8 when the apparatus is packed up; the frame n being.
placed on the tray with the pins rr turned upwards, as shewn in Fig. 4.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The manufacture and use of spirit stoves, and the several appliances thereto,
substantially as herein before described and shewn on the drawings."
2. The manufacture and use of cylinders for roasting coffee, capable of being
opened and closed substantially as hereinbefore described and shewn on the
drawings.
3. The general construction, combination and arrangement of the several and
respective parts, together forming my improved apparatus for roasting coffee, part
of such apparatus being also applicable to other useful purposes, substantially as
herein before described and shewn on the drawings.
