I, HENRY FAULDER, of 7 & 9, Lancashire Bridge, Heaton Norris in the County
of Lancaster Engineer, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN APPARATUS FOR ROASTING COFFEE, cocoa, CHICORY, MALT OR OTHER
SIMILAR SUBSTANCES to be as follows:-
"
My invention relates to improvements in apparatus for roasting coffee, cocoa,
chicory, malt or other similar substances in which a revolving cylinder charged
with the substance to be roasted is heated by a mixture of gas and air or
otherwise.
The object of my invention is to provide means by which the beat in the cylinder
is better retained and will have a more beneficial effect upon the substance to
be roasted and cause the husks to be carried out of and be deposited outside the
cylinder.
To this end I arrange or form an outlet or chimney at one end and in the centre
of this revolving cylinder containing the charge or substance to be roasted, such
outlet or chimney serving also as an axle for that side, instead of having a chimney
fixed to the outer casing of the apparatus.
This outlet or chimney has the form of a pipe, one end projecting into this
revolving cylinder and being bell-mouth shaped, in order that any substances that
might be thrown near to the outlet will not enter the pipe, the other end passing
through the bearing and being connected to a fixed elbow or T piece. This elbow
or T piece is so formed that the husks which will be deposited therein can be
easily removed and, a pipe connected there with will cause a constant draught which
will draw the gases out of the revolving cylinder, and exhaust the same at any
convenient place.

I, HENRY FAULDER, of 7 and 9 Lancashire Bridge, Heaton Norris in the County
of Lancaster, Engineer, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN APPARATUS FOR ROASTING COFFEE, COCOA, CHICORY, MALT, OR OTHER
"SIMILAR SUBSTANCES and in what manner the same is to be performed to be
particularly described & ascertained in & by the following statement :-
"
My invention relates to improvements in apparatus for roasting coffee, cocoa,
chicory, malt or other similar substances, in which a revolving cylinder charged
with the substance to be roasted is heated by a mixture of gas and air or
otherwise.
The object of my invention is to provide means by which the heat in the
cylinder is better retained, and will have a more beneficial effect upon the sub-
stance to be roasted, and cause the husks to be carried out of and be deposited
outside the cylinder.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indi-
cating like parts in the various figures.
Fig. 1 is a cross section and Fig. 2 a longitudinal section of an apparatus for
roasting coffee, cocoa, chicory, malt or other similar substances.
a is the frame, 6 the bearings, c. the fast, & d the loose pulleys e the revolving
cylinder, the coffee tester, g the outer casingh the hopper for charging the
cylinder with the substance to be roasted, i the burner, the gas inlet, and 7 the
air inlet pipe, m the truck into which the roasted coffee is discharged.
In carrying out my invention I arrange or form an outlet or chimney at one end
and in the centre of the revolving cylinder e, containing the charge or substance to
be roasted, such outlet or chimney serving also as an axle for that side or end of
the cylinder e instead of having a chimney fixed to the outer casing g of the
apparatus.
This outlet or chimney is in the form of a pipe l¹, one end of which is pro-
jecting into this revolving cylinder e and being bell-mouth shaped at n in order
that any substances that might be thrown near to the outlet will not enter the
pipe l.
The other end, carried by a support o is passing through the bearing b and is
connected to a fixed elbow or T piece p.
This elbow or T piece at its lower end is provided with a lid r and so formed
that the husks will get deposited therein and can easily be removed by opening
the lid r..
The pipe q, connected at the upper end of the elbow or T piece p, causes a
constant draught which will draw the gases out of the revolving cylinder e,
& exhausts the same at any convenient place.

page_text: Having now 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 :-
First. Providing or forming the rotary cylinder e, on one end thereof, and in the
centre, with an outlet, chimney or hollow axle 1, substantially as described, and for
the purpose specified.
Second. The outlet or chimney I formed with a bell mouth shaped end n pro-
jecting into the cylinder e, and elbow or T piece p connected to the opposite end
thereof, for depositing and collecting the husks, & exhausting the gases from the
cylinder e, as described & set forth.
