I, HERBERT JOHN HADDAN, of 67 Strand, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention, a communication to mé
from abroad by Charles T. Brown, of 113 Adams Street, Chicago, State of Illinois,
United States of America, Attorney at Law, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to the construction of an apparatus for the drying of
meats, or for the smoking of meats, or for the smoking and drying of meats; that
is to say, either the smoking or drying of meats, as preferred, or both smoking and
drying of meats; if desired.
:
The object of the invention and of the apparatus embodying the same is to
obtain an economically constructed smoke and dry house, wherein, at a less cost
than has heretofore been done, meats may be evenly and quickly dried; or dried
and smoked, or smoked; and the said apparatus to be suitable, for the reasons
hereinafter given, for general use; as, by persons largely or exclusively engaged
in the drying or drying and smoking of meats, by dealers in meats desiring to dry
or smoke, or dry and smoke a limited quantity of meats, and by persons wishing
to dry, or smoke, or dry and smoke meats for home consumption, merely..
Complete and perfect control of the drying chamber and the contents thereof, is
attained by the use and employment of the generator herein described, when taken
in connection with the other inventions and improvements herein. set out,. and a
very even distribution of the heat and smoke in said chamber. is secured....
✗ is the outer shell or 'case of the generator used in this invention.
X is a door in the front of-shell or case X.
X² are dampers.
t
r
A is a smoke and heat flue; forming a conduit between the smoke and heat
generator and the diverging flues B, B, B.
B, B; B, are flues forming conduits into the smoking and drying chamber.
b, b, are dampers in flues B, B, B. ·

page_text: E, E, are caps placed over flues B, B, B, in the smoking and drying chamber.
e, e, e, are legs or supports of cap E.
F, is a slide or hood on cap E.
G is a fire box in generator X.
H, H, are grate bars in fire box G.
I, I, are standards on fire box G, adapted to hold flanged or grooved pulleys.
K, K, are flanged or grooved pulleys.
L, L, are tracks or ways for pulleys K, K, on the bottom of shell or case ✗, of
the generator.
If a flanged wheel, as illustrated in Fig. 3 is used, on fire Box G, a flat or
common Trail may be used in the invention. In case a wheel of other shape be
preferred, as a grooved wheel or wheel fitting in a groove in the shell or case serving
as a way, a suitable tram-way must be provided for the wheels or pulleys.
2.1
The track extends from the door X¹ in the front part of the generator.X, to the
extreme rear end of said generator, Fire box G is moved forward in any desired
position by an ordinary hook or draw bar.
When the generator is used in the "pale drying" of meats, as it is termed, coke
or other non-smoke producing fuel is burned in fire box G. Very satisfactory
results by the use of this invention have been obtained in pale drying in the use
of hard wood as a fuel. In the smoking of meats, the ordinary smoke-producing
fuels heretofore used are burned.
In addition to the ease with which the fire is controlled in the generator when
constructed with a moveable fire-box as herein described, both in the starting and
extinguishing thereof, the amount of heat,, or smoke; or heat and smoke generated
'can be regulated in a much better and more complete manner than can be done by
a stationary fire-box or by the use of the bottom of the generator for the building
of a fire thereon.
t
Two or more diverging flues B, B, leading from smoke and heat flue A into the
drying and smoking chamber are used as desired, the number of such flues being
in a manner controlled by the size and shape of the drying and smoking chamber:
the object being, in the use of the diverging flues, to distribute the heat from
generator X in the drying and smoking chamber, comparatively evenly, and
independent of the use of the caps placed over said flues and the' slides placed
thereon.
The flues A and B, B, form continuous conduits between the furnace and the
drying and smoking chamber, and the dampers b, b, in flues B, B, render it possible
to divert the whole or any portion of the current of heated air of smoke in flue A,
into, any one or more of the diverging flues B, 'B, B, in its passage to the drying
and smoking chamber; or as well, if desired, to prevent said current of heated air
or smoke from entering into the drying and smoking chamber, in which case, one
of the diverging flues B, B, or a duplicate thereof having a like damper b, therein,
is made to connect in a suitable manner with the open air without entering said
drying, and smoking chamber.
To more thoroughly distribute the heat and smoke currents in the drying and
smoking chamber, as they enter the same through flues B, B, caps E, E, are placed
over said flues, as illustrated, thus forcing said currents to take a lateral direction
near the floor of the drying chamber. Slide or hood F, used in this invention is
found extremely advantageous in controlling the heat and smoke currents, and
causing them to be distributed uniformly throughout the drying chamber. By
the use of these slides or hoods in this invention, the currents of heated air and
smoke are directed towards any given portion of the drying chamber at will.
A suitable opening or ventilator is placed in the ceiling or top of the smoking
anding shamho

page_text: The manner in which the invention is used is as follows:
The articles to be dried or dried and smoked are hung in the drying-chamber in
the ordinary manner. A fire is then started in fire-box G in generator X, the
materials employed as fuel, being such as to produce heat currents in flue A, and
diverging Bues B, B, having but little smoke therein. By means of the dampers b, b,
the drying chamber is quite uniformly heated; caps E, E, and slides or hoods F,
also tending to assist in the distribution of said currents, evenly throughout said
chamber, thus equalizing the temperature thereof. Where meats are to be subjected
to "the pale drying process," so-called, no other treatment is necessary. When the
meats are to be dried and smoked, saw dust or other suitable material is placed in
fire-box G, when the contents of the chamber are sufficiently dried, for the purpose
of producing as required, a more or less dense smoke, which is conveyed into the
drying chamber in the manner hereinbefore described, and controlled and guided
as set forth by means of dampers b, b, caps E, E, and slide or hood F.
Having now fully 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 ;-

smoking and drying chamber, having flues or conduits with dampers therein,
leading from said furnace into said drying chamber, all substantially as described,
and for the purpose set forth.
2. In an apparatus for smoking and drying meat, a generator placed outside of
the smoking and drying chamber, having flues or conduits, with dampers therein,
leading from said generator into said drying chamber, in combination with caps
and slides or hoods adjustable around said caps, all substantially as described and
for the purpose set forth.

all substantially as described.
5. In an apparatus for smoking and drying meats, a generator having a moveable
