PROVISIONAL SPECIFICATION.
Improvements in Treating Vitreous Substances for Making Metallic
Connections thereto.
We, HENRY DOULTON, Knight of the Lambeth Pottery, Lambeth, in the
County of Surrey and JOHN SLATER of Waterloo Road, Burslem, in the County
of Stafford, Potter do hereby declare the nature of our said invention to be as
follows:-
:-
Our invention refers to an improved method of making metallic connections to
vitreous substances such as earthenware, china or glass as a substitute for the
present plaster and other imperfect connections, say, as applied to earthenware
water closets.
In carrying out our invention we prepare the earthenware at the place where the
metal pipe connections are to be made, say, the water inlet pipe and the soil outlet
pipe by forming thereon a metallic surface in the manner bereinafter described and
to which we are enabled to solder the said metal pipes by an ordinary soldering
tool or other means.
It will be obvious that a sealed joint of this character possesses important
sanitary advantages over the present india rubber or putty joints. In the case of
bath sinks, lavatories, cabinet-stands, plug basins, urinals and similar earthenware
articles to which it is desirable to connect metal pipes we prepare the earthenware
surface where the connection is to be made in the manner bereinbefore mentioned
and when necessary modify the shape of the part to facilitate the soldering. When
desirable metal unions may be attached in this manner to the earthenware to
afterwards receive the pipe connection or other metallic connections may be made
for other purposes the special feature of our invention being the preparing of the
surface where it is desired to make a metallic connection by an ordinary soldering
or plumbing joint.
Our invention further has for its object the attaching of metal mounts to vitreous
surfaces such as the mounts of scent bottles and spirit flasks heretofore fastened
with cement attaching metal handles to jugs; mounts for water dishes and plates;
tea pot handles and spouts; taps for filters and urns and all similar purposes where
the connection has hitherto been imperfect and uncertain and consists in preparing
the vitreous surface at that part as hereinafter described and thus we are enabled to
firmly secure the parts together by soldering. In like manner earthenware handles
for instance may be secured to jugs or pitchers so as to facilitate renewal in case of
breakage.
Our invention also refers to the use and application of this method of joining in
connection with electrical fittings and appliances in lieu of the present system of
clamping screws say, as applied to earthenware switches and pushes. Instead of
the usual screws and fittings we prepare portions of the surface of the push or
switch as before mentioned and affix the wires or other parts by an ordinary
soldering tool.
It will be obvious that such a method possesses great advantages over the present
clamping devices in cheapness and certainty of electrical contact.
The preparing of the vitreous surface hereinbefore referred to may be done in
accordance with the Specification for which Letters Patent were granted to one of
John Slater, on the 8th day of October 1891 and numbered 17,126 and we have
also found the following effective for the purpose :-
us,
:-
One drachm of bi-chloride of platinum well washed to eliminate the free acid, to
which add once ounce of balsam of sulphur and three ounces of spirit of turpentine
boiled to the consistency of cream in a sand bath. Now take the platinum and put

page_text: it on a slab slightly heated so as to evaporate any moisture left from the washing
and while warm mix the balsam with the metal adding oil of turpentine till the
proper consistency for working with a camel hair brush is obtained and with this
coat the vitreous surface and afterwards fire in a kiln at a suitable temperature.
Although we have found the foregoing to be effective for preparing the surface
we may use oxide of gold or silver or platinum sponge or other metallic compounds
which will in the same or similar manner adhere to the vitreous substance and
which will take the solder in the manner herein before described.
Dated this 13th day of July 1892.

COMPLETE SPECIFICATION.
Improvements in Treating Vitreous Substances for Making Metallic
Connections thereto.
We, HENRY DOULTON, Knight, of The Lambeth Pottery, Lambeth, in the
County of Surrey, and JOHN SLATER, of Waterloo Road, Burslem, in the County
of Stafford, Potter, do hereby declare the nature of our said invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
Our invention refers to an improved method of making metallic connections to
vitreous substances such as earthenware, china or glass as a substitute for the
present plaster and other imperfect connections, say, as applied to earthenware
water closets.
In carrying out our invention we prepare the earthenware at the place where the
metal pipe connections are to be made, say, the inlet water pipe and the soil outlet
pipe by forming thereon a metallic surface in the manner hereinafter described and
to which we are enabled to solder the said metal pipe by ordinary solder and tools
used by plumbers.
It will be obvious that a sealed joint of this character possesses important
sanitary advantages over the present india-rubber or putty joints. Similarly in
the case of baths, sinks, lavatories, cabinet-stands, plug-basins, fountains, urinals,
and other articles to which it is desirable to connect inetal pipes we "prepare" the
earthenware surface where the connection is to be made and when necessary modify
the shape of the part to facilitate the soldering. When desirable metal unions may
be attached in this manner to the earthenware to afterwards receive the pipe
connection, or other metallic connections may be made for other purposes. The
special feature of our invention is therefore the "metallising" or preparing of the
surface of vitreous substances such as earthenware, china or glass where it is
desired to make a metallic connection by an ordinary soldering or plumbing joint.
Our invention further has for its object the attaching of metal mounts to vitreous
surfaces such as the mounts of scent bottles and spirit flasks heretofore fastened
with cement; attaching handles to vases or jugs; mounts for dishes and plates;
teapot handles and spouts; taps for filters and urns and all similar purposes where
the connection has hitherto been imperfect and uncertain and consists in
"preparing the vitreous surface at that part as hereinafter described and thus we
are enabled to firmly secure the parts together by soldering. In like manner
earthenware handles for instance may be secured to jugs or pitchers so as to
facilitate renewal in case of breakage.
Said improvements are also applicable for sealing the lids of jars containing
preserved fruits, vegetables and the like.
Our invention also refers to the use and application of this metallising or
soldering process in fastening down electrical fittings and appliances in lieu of the
present system of clamping screws, say, as applied to earthenware switches and
pushes. It will be obvious that such a method possesses great advantages over the

page_text: present clamping devices and certainty of electrical contact, or a portion or portions
and the wire soldered
of the surface of the earthenware may be "metallised
thereto direct so dispensing with the metal fittings in certain cases.
To prepare the metallised surface herein before referred to we take one drachm
of bi-chloride of platinum well washed to eliminate the free acid and then prepare
one ounce of balsam of sulphur and three ounces of spirit of turpentine (by boiling
the same to a consistency of cream in a sand bath). We next take the platinum
and put it on a slab slightly heated so as to evaporate any moisture left from the
washing and while warm mix the balsam (before described) with the platinum
adding oil of turpentine until the proper consistency for working with a camel hair
brush or pencil is obtained and with this we coat the vitreous surface at the desired
part and afterwards fire in an enamel kiln at a suitable temperature.
Although we have found the foregoing to be effective for preparing the
"metallised" surface we may use oxide of gold, silver, or platinum sponge or other
similar metallic compounds which will in the same or a similar manner adhere to
the vitreous substance and which will take the solder in the manner hereinbefore
described.
Having thus particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is -
1st- Metallising" or preparing the surface of articles of earthenware, china or
glass where it is desired to make soldered connections thereto substantially as
hereinbefore described.
2nd The herein before described process for "metallising" or preparing vitreous
surfaces for the purpose set forth.
