PROVISIONAL SPECIFICATION left by the said Joseph Ingleby at the Office

JOSEPH INGLEBY, of No. 7, St. Peter's Square, Manchester, in the County of
"Lancaster. "IMPROVEMENTS IN COCKS, VALVES, VALVE BOXES, AND RECEPTACLES
OR CONDUITS FOR USE WITH ACIDS." [A communication from abroad by Robert
Meyer, of Breslau, in the German Empire.]
The present Invention has for its object to construct cocks, valves, valve-boxes,
and receptacles or conduits for use with acids in such a manner that at all points
where the said cocks, valves, receptacles, &c., are brought in contact with the acids,
the metal or material of which they are constructed is provided with a lining,
coating, or covering of uniform thickness of a metal or material that will not be
affected by the acid, such as lead, alloys of lead and antimony, caoutchouc, solutions
of india rubber, mixtures of blacklead, clay, earthenware, porcelain, &c., such lining
-being produced by casting it in a molten or liquid state on to the surfaces to be
protected.
For this purpose the body of the valve casing, cock, or receptacle is made of
larger internal size than the finished internal chamber or space therein is required
to be, and it is made of two or more separate parts to enable a core to be inserted
into it, which is made of the exact size and shape required for the internal chamber
or space.
Thus a narrow space of uniform width will intervene at all points
between the surface of the core and the internal surface of the casing, so that on
running the molten or liquid non-corrosible material above referred to into such
space the internal surface of the said body will become coated with a lining of any
desired thickness of such material.
The separate parts of the body have external flanges by which they may be
secured together.
.
In some cases, according to the configuration of the article to be so coated, the
body thereof may be made of one piece, and the core be made of two or more pieces
introduced separately through the aperture or apertures of the body and fitted
together inside the same.

JOSEPH INGLEBY, of No. 7, St. Peter's Square, Manchester, in the County of
Lancaster. "IMPROVEMENTS IN COCKS, VALVES, VALVE BOXES, AND RECEPTACLES
OR CONDUITS FOR USE WITH ACIDS." A communication from abroad by Robert
Meyer, of Breslau, in the German Empire.
The present Invention has for its object to construct cocks, valves, valve boxes,
and receptacles or conduits for use with acids in such a manner that at all points
where the said cocks, valves, receptacles, &c., are brought in contact with the acids,
the,metal, or, material of which they are constructed is provided with a lining,

affected by the acid, such as lead, alloys of lead and antimony, caoutchouc, solutions
of india rubber, mixtures of blacklead, clay, earthenware, porcelain, &c., such lining
being produced by casting it in a molten or liquid-state on to the surfaces to be
.protected.

For this purpose the body of the valve casing, cock, or receptacle is made of
larger internal size than the finished internal chamber or space therein is required
to be, and is made of two or more separate parts to enable a core.to be inserted
into.it, which is made of the exact size and shape required for. the internal chamber
. or space. Thus a narrow space of uniform width will intervene at all points
between the surface of the core and the internal surface of the casing, so that on
running the molten or liquid non-corrosible material above referred to into such
space, the internal surface of the said body will become coated with a lining of any
desired thickness of such material. The separate parts of the body have external
flanges, by which they may he secured together.
In some cases, according to the configuration of the article to be so coated, the
body thereof may be made of one piece, and the core be made of two or more pieces
introduced separately through the aperture or apertures of the body and fitted
together inside the same.

The accompanying Drawing shews by way of example a valve box constructed
according to the above described Invention. Fig. 1 is a longitudinal, and Fig. 2 a
transverse section.
The casing A is made in two halves provided with flanges by which they are
bolted together after the insertion of the core, the internal spaces being of larger
dimensions than they are required to be when finished. A core having been
inserted within the casing of the exact finished 'size of the passages, so as to leave a
narrow space all round between the core and the shell, this space is then run in
with lead or other non-corrosible substance B which consequently forms a lining
to the casing when the core has been removed. The cover C is in like manner
provided with a lining D, and the valve E with its stem is also provided with 'a
covering F of non-corrosible material."

Having thus.described the nature of the said Invention, and in what manner the
same is to be performed, as communicated to me by my foreign correspondent, I
claim,―
Providing cocks, valves, valve boxes, receptacles, or conduits with a lining of
non-corrosible material by making the casing of two or more parts, and of larger
internal size than required, and after introducing therein a core of such a size as to
leave a space at all points between it and the interior of the casing, running into

page_text: such space the non corrosible material required for forming the lining, substantially
as herein described.
In witness whereof, I, the said Joseph Ingleby, have hereunto set my hand
and seal, this Tenth day of September, in the year of our Lord One thousand
eight hundred and eighty-one.
JOSEPH INGLEBY. (L.S.)
