page_text: I GEORGE MARTIN NICOLAUS, Manager of Queen Anne's Mansions, Saint James'
Park in the County of Middlesex, do hereby declare the nature of this Invention
to be as follows:-
It has been found that the exhalation which is given off into the air by certain
kinds of tar, very beneficial medicinally when inhaled by persons suffering from
affections of the lungs, respiratory organs, or the like.
The object of this Invention is to provide a convenient portable apparatus for
holding such tar, whereby a large surface of the said tar may be exposed to the air
in as small a space as possible.
In carrying out this Invention I place the tar in a metal box, case, or receptacle
(which I will hereinafter term "the tar receptacle "), which I prefer to make
oblong in shape and of greater depth than width, and I furnish this tar receptacle
with a lid to overlap the sides of the receptacle when the apparatus is closed up,
the said lid to be provided with means by which it can be fixed at different
heights above the tar receptacle-These means may consist of strips of metal
attached to two or more sides of the lid and projecting vertical downwards and
sliding in guides or guide pieces attached to the outer sides of the tar receptacle,
suitable means being provided to fix the said strips in the guides at a required
height, and thus prevent them sliding up and down therein-The lid is also
furnished with a handle on the upper side, by which the apparatus can be lifted
whether it be open or shut.
To the underside of the said lid, at right angles thereto, and hanging vertically
downwards into the tar receptacle, I then attach the top edges of a series of
perforated plates, which plates, when the lid is raised, will also be raised out of
the tar receptacle, suitable projections being formed inside the tar receptacle to
steady the said plates when drawn up very high. Strips of metal are soldered
across the bottom and end edges of the plates to connect them together and at the
same time keep them equidistant.
'On the lid being shut down the perforated plates will become immersed in the
tar. When the lid is drawn up again the surfaces of the plates raised therewith
will be coated with tar, which will commence slowly to run off again into the tar

page_text: receptacle, the perforations in the plates tending to retard the downward flow
thereof. The air, on circulating between and around the perforated plates, becomes
quickly impregnated with the tarry exhalation, which it carries off into the room
or place where the apparatus standing, the said exhalation being thus inhaled
with the ordinary atmosphere by persons in the said room or place. I use vertical
plates because the motion of the tar in running off gives off greater exhalation than
when the tar is still.
Feet provided with circular holes for fixing the same easily with nails or screws,
may also be added to the apparatus.
The surface of the plates in an ordinary apparatus and when drawn up to the
full height is equal to a square yard or thereabouts of surface exposed to the air.

page_text: I, GEORGE MARTIN NICOLAUS, Manager of Queen Anne's Mansions, St James'
Park, in the County of Middlesex, 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 :-
It has been found that the exhalation which is given-off into the air by certain
kinds of tar acts as a thorough disinfectant and is very beneficial medicinally
when inhaled by persons suffering from affections of the lungs, respiratory organs,
or the like.
. The object of this Invention is to provide a convenient portable apparatus for
holding such tar, whereby a large surface of the said tar may be exposed to the
air in a very small space.
This apparatus consists of a metal box, case, or receptacle (preferably oblong in
shape, and of greater depth than width) into which the tar is placed, and which is
hereinafter termed the "tar receptacle." This tar receptacle is provided with a
metal lid having overlapping edges, and suitable means are employed by which the
said lid can, when raised, be fixed at different heights above the tar receptacle so
as to be incapable of moving up or down, thus enabling the apparatus whether
open or shut to be carried about by a handle on the upper side of the lid. To the
underside of, and at right angles to, the said lid are attached lengthwise, and
equidistantly apart, the top edges of a series of perforated metal leaves or plates,
which hang down vertically into the tar receptacle, and which, on the lid being
raised or lowered, will consequently be raised or lowered also. The leaves or
plates, on the lid being shut, will become immersed in the tar, with which their
surfaces will be coated when the lid is raised again.
And in order more clearly to explain the Invention I will now proceed to
describe the same with reference to the accompanying drawings in which similar
letters of reference indicate corresponding parts in all the Figures.
Figure 1 represents a side view of an oblong apparatus with the lid shut down
and shewing the mechanism which I prefer to use for raising and fixing the lid.
Figure 2 is a similar view with the lid raised to shew the perforated plates.
Figure 3 shews the apparatus with the lid raised, but with one side removed.
Figure 4 is an end view of same with one of the ends removed.
A is the oblong tar receptacle which is filled with the tar, and A¹ are feet for
fastening the apparatus in a particular spot. B is the lid and B¹ the lid-handle.
In Figures 1 and 2 C is a strip of metal attached to the lid B, and sliding in guide
pieces D, attached to the side of the receptacle A. C¹ is a tube or more properly
speaking a succession of tubes soldered to the strip O with spaces between for the
passage of a bolt or spring E. E' is a loose pin to be inserted in the tube to
prevent the bolt or spring E from bending outwards. In Figures 2, 3, and 4,
F are the metal plates, of which six are represented in Figure 4, pierced by
perforations G, and connected together and kept equidistant by strips of metal H
(Figure 4). In Figure 4, J, J, are projections, which touch the outer sides of the

page_text: framework of plates and steady it when raised, and K are the equal spaces
between the plates.
To raise the lid B the pin E is taken out and the bolt or spring E withdrawn,
when the strips C will slide up in guides D, the fixing being effected by pushing
the bolt or spring E into any of the spaces between the tubes C³, and reinserting
pin E¹. I do not however limit myself to the means here shown for fixing the
lid B.
In Figures 3 and 4 it will be seen that when the lid B is shut, the perforated
plates Fattached thereto and connecting bars H will become immersed in the tar,
and that when the lid B is raised, the plates F will be coated with tar, which will
slowly run off again, the perforations & tending to retard this downward motion.
The air, on circulating between and around the plates F, and coming in contact
with the tar while the latter is in motion, causes an evaporation or exhalation
from the tar which soon impregnates the general atmosphere and is inhaled there-
with by persons who are in the same apartment with or near to, the apparatus.
Assuming the plates. F to be 10 or 11 inches in length, when they are fixed at
their full height their twelve sides will expose to the air a surface of about, a
square yard The apparatus, whether open or shut, can be carried about by the
handle B¹, provided that the strips O on each side of it are fixed in their guides D.
Having now particularly described and ascertained the nature of this: Inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:
.
In apparatus for holding and exhaling tar for medicinal purposes,
1. The use of a series of metal plates to increase the surface of tar exposed to
the air in a small space, for giving off a beneficial exhalation, substantially as
herein before described and illustrated in the accompanying drawings.
2. The vertical arrangement of the plates for the purpose of giving motion to
the tar whereby a much greater exhalation is given off, as hereinbefore described,
and illustrated in the accompanying drawings.
3. The use of perforations in the said plates for retaining the tar thereon to
prevent it flowing down too rapidly, as herein before described.
4. The method of raising and lowering the plates by attaching them to the, lid
and the use of means for fixing the lid and plates when raised, substantially as
berein before described and illustrated in the accompany drawings.
5. The whole combination and arrangement of parts substantially as herein-
before described and illustrated in the accompanying drawings.
