PROVISIONAL SPECIFICATION.
Improvements in and connected with the Process of Smoking Bacon
and other Meat.
I, FREDERICK COURTLAND TYRRELL, of 65, Market Street, Eastleigh, in the
County of Hants, Bacon Curer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to the process of smoking bacon and other meat.
The main object of my said invention is to provide improved apparatus and
means for smoking bacon and other meat.
According to the practice now generally adopted when smoking bacon and
other meat, the material used in the kilns-usually consisting of oak dust-is
lighted immediately under the meat and the consequent heat acting directly on
the meat causes it to shrink and lose weight to a considerable extent.
According to my invention I adopt means and apparatus for preventing the
meat from being subjected to direct heat, with the consequent disadvantages afore-
suid.
In carrying out my invention I provide a furnace, situated preferably under-
ground, in which the sawdust or other material used for smoking the meat is
burnod.
The kiln in which the meat is smoked will be situated some distance from the
furnace and is supplied with smoke from the furnace by means of a main pipe
and branches, as desired, communicating with same, the main pipe after leaving
the furnace passes watertight through a watertank the water in same being kept
in circulation by means of inlet and discharge pipes thereby keeping the tempera-
ture of the water in tank down, and consequently of the smoke passing through
the pipes which will therefore arrive at and be discharged into the kiln through
the branch pipe or pipes at a low temperature. It is obvious that any convenient
number of kilns may be supplied with smoke by means of branch pipes from
the main pipe leading from the furnace, and further my improvements may be
applied to existing kilus.

and other Meat.
I, FREDERICK COURTLAND TYRRELL, of 65, Market Street, Eastleigh, in the
County of Hants, Bacon Curer, 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:
:-
My invention relates to the process of smoking bacon and other meat.
The main object of my said invention is to provide improved apparatus and
means for smoking bacon and other meat.
According to the practice now generally adopted when smoking bacon and other
meat, the material used in the kilns-usually consisting of oak-dust-is lighted
immediately under the meat which is suspended in the kiln, and the consequent
heat acting directly on the meat causes it to shrink in weight to a considerable
and unprofitable extent.
According to my invention I provide means and apparatus for preventing the
meat from being subjected to direct heat while being smoked, with the consequent
disadvantage aforesaid.
In the accompanying drawings I have shewn what I consider to be the best
means of carrying out my invention in which :-
Fig. 1 is an elevation partly in section, taken on the line a a
Fig. 2 a plan taken on the line b b.
Fig. 3 a cross sectional view taken on the line c c.
Like letters indicate corresponding parts throughout the drawings.
In carrying out my invention 1 provide a furnace A, situated preferably
underground in which the sawdust or other material used for smoking the meat
is burned; B, is a kiln (shewn in sectional elevation in Fig. 1) in which the
meat is smoked, situated some distance from the furnace A; Cis the main smoke
pipe leading from the crown of furnace to the kiln with branch pipes D, D, D,
led under the floor e, of the kiln and up through same, the outlets being covered
with gratings E, E, E.
I prefer that the main smoke pipe C shall have a slight rise lengthways, from the
furnace to the kiln.
The main pipe C after leaving the furnace passes watertight through a water-
tank F, the water in same is kept at will in circulation by means of inlet and dis-
charge pipes G, G, thereby keeping the temperature of water in the tank down,
and consequently the smoke passing through the main pipe on its way to the kiln,
where it is discharged through the gratings E, E, E, into the kiln at the required
temperature.
H, is the door into the kiln.
The meat will be suitably suspended in the kilu so as to allow the smoke to
play around same, and the kiln will contain nothing else but the meat and smoke,
not any fire, as is the case with kilns now ordinarily made for smoking meat.
The supply of smoke to the kiln may be controlled by suitable cocks valves or
dampers fitted to the supply pipes.
Suitable ventilators will also be fitted to the kiln, and I may fit a draught
louvre f, in the furnace door so as to regulate the draught in furnace without
opening the furnace door.
Suitable portable coverings will be fitted over the channel J in which the pipes
and tank are placed.
I have shewn in the drawings only one kiln, but it is obvious that by means
of a series of branch pipes from the main pipe the same may be arranged to feed

page_text: any convenient number of kilns simultaneously, or intermittently if desired, by
the manipulation of cocks or similar contrivances fitted for the purpose.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
1st. The improved smoking apparatus for bacon and other meat, all constructed
and combined substantially as described with reference to the accompanying draw-
ings, and operating as, and for the purpose specified.
2nd. In combination, the smoking apparatus described having a furnace A, a
water tank F, a pipe C, and branch pipes, adapted to lead the cooled smoke to an
independent kiln or kilns as, and for the purpose specified.
3rd. The herein described method of smoking bacon and the like goods in a
kiln, in which there is no direct contact of the goods with the material and fire
used for the supply of smoke, for the purpose above specified.
4th. In a smoking apparatus for the above named purpose the use and method
of passing the smoke supply pipes through a water chamber as, and for the purpose
above specified.
