HARRY STOCKMAN of Sea Houses North Sunderland in the County of Northumber-
land Civil Engineer do hereby declare the nature of this invention to be as follows:-
The process the subject of my invention is for smoking articles of food and articles
that require disinfecting by compressed smoke.
As an example of how this process may be performed-I compress smoke into a
Receiver by means of a pump or pumps-I make the receiver of iron or other material
to resist the required pressure and to any shape suitable for the articles to be treated
by this process.
1 also form in the Receiver openings for putting in or taking out the
said articles and I fit these openings with doors or covers so that when closed the
Receiver will be air tight. I also make an inlet in the Receiver which I connect to
the delivery or discharge of the pump or pumps and through which the smoke is forced
into the Receiver-I form the feed of the pump or pumps in a flue or compartment
where the smoke is generated-I may by intercepting or shutting off the smoke from
the pump or pumps, pump air instead into the Receiver for the purpose of dispersing
or emptying the same of smoke.
The receiver may be fitted with the ordinary boiler mountings for indicating or
relieving the pressure.

page_text: I HARRY STOCKMAN of Sea Houses North Sunderland in the County of Northumber-
land Civil Engineer 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 is for preserving or disinfecting by compressed smoke.
In the accompanying drawing I have illustrated one form of machine as constructed
in accordance with this invention.
Figure, 1, represents a generator for generating smoke. Figure, 2, a pump for
forcing smoke into a Receiver. Figure 3, a Receiver in which the articles to be
treated by this process are placed.
In carrying the said invention into practice as illustrated in the drawing―
I employ a chamber (Fig. 1.) for generating the smoke which I have called the
"Generator to which is attached a flue or chimney H connected by a branch to
pipe A communicating with the pump. At the top of the flue or chimney I have a
damper K for regulating the draught and at the other end of the Generator I have
a door in which are openings with shutters also for regulating the draught―Thus
the material from which it may be desired to obtain smoke is placed on the floor
or hearth of the Generator and ignited and a draught created through the Generator
by working the pump and drawing air through the openings at the door of the
Generator or by lifting the damper K in conjunction with the said openings.
For conveying the smoke to the pump I employ the pipe A and at a point on the
said pipe I have a valve B for intercepting or shutting off the smoke from the pump,
and on the same pipe A between the valve B and the pump I have another valve C
for admitting air to the pump to disperse or empty the Receiver of smoke. I connect
the discharge of the pump to the Receiver by a pipe D. Fitted to the Receiver
I have a door E for putting in or taking out the articles to be treated by this process.
I also have fitted to the Receiver a valve F for relieving the pressure and a pressure-
gauge G for indicating pressure.
In using the machine as described the articles to be treated are placed in the
Receiver by the door E which is then closed and the smoke is forced into the Receiver
by the pump through the pipe D the pump being fed through pipe A communicating
with the Generator but when dispersing the smoke from the Receiver the smoke is
shut off from the pump by the valve B and air is admitted by opening the valve C.

page_text: The shape or number of parts shewn on the accompanying drawing may vary to
suit the different articles to be treated by this process. The pump or pumps may be
worked by hand or other power.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same can be performed I declare that what I claim is :-
First The process of subjecting articles to compressed smoke by the means
substantially as herein set forth.
Second-The combination with Figures 2 and 3 of an inlet for the admission of
air substantially as and for the purpose specified.
