PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 12th July 1877.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN APPARATUS FOR PURIFYING
OZONE." [A communication from abroad by Frederick William Bartlett, of Buffalo,
New York, United States of America, Physician.]
This Invention relates to further improvements in the apparatus described in
the Specification of my former Letters Patent, dated 20th September, A.D. 1875,
No. 3294.
My improved apparatus has a peculiarly formed glass base, whose diameter is
enlarged at its lower part to give additional support, and render the vessel less
likely to upset; it is also enlarged at its upper part to render it capable of receiving
and supporting a porous eliminating chamber of a large diameter at its bottom or
base.
•
The said eliminating chamber has a cone-like form, as described in the said former
Specification. This form counteracts to a great extent the tendency of phosphorous
or phosphoric acids in a vapor form to pass into the porous materials forming the
walls of the said chamber, the specific gravity of the acids thus formed preventing
to a great extent their escape through the lateral walls of the chamber.
I may employ for forming or constructing the walls of the eliminating chamber
of the said ozone apparatus any suitable material which has been chemically treated
by acids or alkalies, or by any manipulation producing the required chemical change
in the substance so treated.
I construct the said apparatus with an expansion dome, which has a vertical wall,
and which tends to prevent the deposit of phosphorous or phosphoric acids upon the

page_text: inner surface of the dome, and thereby facilitates the inspection of the interior of
the apparatus by keeping or leaving the glass walls of the dome constantly clear.
An intermediate collar or stopper is placed between an ornamental hollow stopper
at the top of the said dome. This collar has a central opening for the passage of
the adjusting rod, and is enlarged at its upper surface and formed with a recess for
the reception of an elastic band or pack, which surrounds the rod, and permits its
adjustment to any point desired.
The said apparatus also has a glass or other inoxidizable platform. The said platform
has wings or dividing partitions projecting from its centre laterally and vertically.
Upon the upper edges of these wings one or more slots or depressions are made to
receive one or more concentric wire rings and strips or equivalent pieces to form
supports for the phosphorous attachments, whereby cach piece of phosphorus is sus-
pended in a space between the said partitions or wings. I use fusible metal,
especially that produced by the combination of lead, tin, and bismuth, for forming
the said wire rings or other supports or devices employed for suspending the pieces
of phosphorus, so that prompt submergence may follow ignition of the phosphorus.
I use gold, platinum, varnish, lacquer, or other suitable substance to cover exteriorly
the fusible rings or phosphorus or supports, to prevent their oxidation by ozone or
phosphoric oxides.
I may provide the said apparatus with a cord composed of any suitable material,
and so prepared chemically as to readily ignite to take the place of the above-
described sustaining fusible ring, the object to be obtained by this contrivance being
the prompt submergence of any piece of phosphorous which may ignite by severing
the supporting cord.
I may, use fusible metal wires or strips platinized, gilded, varnished, lacquered, or
otherwise protected from oxidation, and any form of cord made readily ignitable to
suspend phosphorus in pieces of any shape or form in the apparatus, whether the
pieces of phosphorous are separated by partitions from each other, or are ozidized in
an open space without such separation.
I provide phosphorous cavities in sections, which may comprise any number of
tubes. The sections may be removed or replaced at will to secure any degree of
ozonization required for hospitals or ships, or for any required purpose.
If necessary or desirable I provide a porous jacket of any suitable material
externally over the finished eliminating chamber to permit the completion of the
purification of the ozone in varying conditions of the atmosphere.

the said William Robert Lake in the Great Seal Patent Office on the 12th
January 1878.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN APPARATUS FOR PURIFYING
OZONE." A communication from abroad by Frederick William Bartlett, of Buffalo,
New York, United States of America, Physician.
This Invention relates to further improvements in the apparatus described in
the Specification of any former Letters Patent dated 20th September, A.D. 1875,
No. 3294.
The said Invention is illustrated in the accompanying Drawing, which I will now
proceed to describe.
Figure 1 is a vertical central section of an apparatus constructed according to my
Invention.
Figure 2 is a plan or top view of a portion of the same detached.
Like letters indicate the same parts in both of these Figures.
:
My improved apparatus has a peculiarly formed glass base a, whose diameter is
enlarged at its lower part a¹ to give additional support, and diminish the liability of
the said vessel to be overturned or upset; it is also enlarged at its upper part a² to
render it capable of conveniently receiving and supporting a porous eliminating,
chamber b, whose bottom or base is formed to fit over and around, the rim a³, and
rests upon a shoulder or shelf a*. I provide the base a with a bent tube a*, with ■
long and short arms as shown, to permit the ready removal of acid accumulations,
and for supplying water to the vessel by the aid of a syphon or pump.
The said eliminating chamber b has a cone-like form, as described in the said
former Specification, and this conical part of the said apparatus constitutes what I
term the delivery walls of the same. This form counteracts to a great extent the
tendency of phosphorus or phosphoric acids in a vaporous form to pass into the
porous materials forming the walls of the said chainber. The specific gravity of
the acids thus formed prevents to a great extent their escape through the lateral
portion or walls of the said chamber.
I may employ for forming or constructing the walls of this eliminating chamber b
any suitable material which has been chemically treated by acids or alkalies, or by any
manipulation producing the required chemical change in the substance so treated.
In some instances I use clay chemically treated as above described. I sometimes
provide the said chamber with a porous covering secured by bands or hoops b¹.
I construct the said apparatus with an expansion dome c, which has a cylindrical
or nearly cylindrical form; this form tends to prevent the deposit of phosphorus or
phosphoric acids upon the inner surface of the said dome, and thereby facilitates
the inspection of the interior of the apparatus by keeping or leaving the glass walls
of the dome constantly clear.
A collar or stopper d is placed at the top of the said dome; this collar has a
central opening for the passage of an adjusting rod herein-after described, and is
enlarged as its upper surface, and formed with a recess d¹ for the reception of an
elastic band or packing which surrounds the said rod, and keeps it tight while per-
mitting its adjustment to any point desired.
The said apparatus also has a glass or other inoxidizable platform e, shewn
detached in Figure 2. The said platform has radial dividing partitions or wings e¹
projecting from its centre, as shown. Upon the upper edges of these wings I form
one or more grooves or depressions e² for the reception of one or more concentric
wire rings, strips, or equivalent pieces, as shewn at f, to form supports for the
phosphorus attachments, whereby each piece of phosphorus f¹ is suspended in one
of the spaces between the said partitions or wings e¹. I use fusible metal, especially
that produced by the combination of lead, tin, and bismuth, for forming the said
wire rings or other supports or devices employed for suspending the pieces of phos-
:

page_text: phorus, so that prompt submergence may follow ignition of the phosphorus. I
prefer that this fusible alloy or compound should be formed of the above metals in
the following proportions, namely:-Lead, five parts; tin, three parts; and bismuth,
eight parts. I also use gold, platinum, varnish, lacquer, or other suitable substance
to cover exteriorly the fusible rings or phosphorus attachments or supports to prevent
their oxidation by ozone or phosphoric oxides.
I may use in place of the above-described fusible ring any suitable ignitable
substance, such as fibrous cords, threads, or strips, prepared chemically by phosphorus
or otherwise to readily ignite, or I may use sealing wax or other readily inflammable
substance in the form of columns or projections, which may be moulded or otherwise
suitably formed to support the phosphorus in the said apparatus, the object to be
attained by this contrivance being the prompt submergence of any piece of phosphorus
which may ignite by severing the supporting ring, cord, wax, or other article or substance,
and I wish it understood that I may use fusible metal wires or strips platinized, gilded,
varnished, lacquered, or otherwise protected from oxidation, and any form of cone
made readily ignitable to suspend the phosphorus in pieces of any shape or form in
the apparatus, whether the pieces of phosphorus are separated by partitions from
each other or are oxidized in an open space without such separation.
In some instances, that is to say, when constructing my Invention on a large
scale, I modify my said Invention by forming phosphorus cavities or receptacles in
sections, which may comprise any number of tubes; these sections may be removed
or replaced at will to secure any degree of ozonization required for hospitals or ships,
or for any required purpose.
I provide my improved apparatus with the adjusting rod of glass or other
suitable material attached to the disc i below the aforesaid platform e; the said rod
is formed in one piece or two or more pieces, with elastic or hinged joints or other
suitable connections, and terminates and is held at the top of the dome by an elastic
band or screw and nut, so that it may be readily raised or lowered.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim in and forming part of an ozone apparatus or machine,-
