PROVISIONAL SPECIFICATION.
Improvements in the Construction of Taps for Steam, Water,
and other Fluids.
We EDGAR FROST, Engine Tenter, and GEORGE HOUGHTON, Engineer, both of
Treeton near Rotherham in the County of York do hereby declare the nature of this
invention to be as follows :-
Our invention relates to improvements in the construction of Taps for Steam, Water,
and other liquids and fluids, and it has for its object to enable certain parts to be
easily renewed when worn or otherwise damaged, without the necessity of removing
the fixed part of the tap; such renewals being repeated as often as required without
injury to the chief portions of the tap.
Our invention consists in providing a removable conical shell or lining to the
barrel or body of the tap, and also a conical external shell or sleeve to the plug of the
tap, thus, according to one method of carrying out our invention, we bore out the body
of the tap to a rather larger size than that of the required plug, and we fit into this
conical space a thin shell of corresponding shape, and prepared to receive the plug.
Various plans may be adopted to fix or secure the shell in its position, such for example
as making a square projection on the underside of the shell and a correspondingly.
shaped recess in the barrel or body to receive it.
We then take the plug which is made of smaller diameter than the conical interior
of the barrel-shell before described, and we make an
exterior shell of any
suitable metal to fit upon the said plug, the outside being formed to fit into the
conical-barrel-shell.
The plug shell or sleeve may also be secured to the plug in the same manner as that
already described with reference to the barrel shell, and either of them may be finally
secured by means of a screw and nut or by other equivalent devices.
We may if found desirable apply the removable shell to the barrel alone, and fit a
solid plug to the interior of the said shell, the plug being usually much more easily
removed and less costly to renew than the barrel.
Dated the 14th day of April 1888.

page_text: Various devices may be used to secure the shells, such for instance as those
described, but we do not bind ourselves to any particular method of accomplishing
this end.
The shells or removable parts may for example be made of the very best and most
durable metal suited for the purpose, and the body of cheaper material, so that the
greatest efficiency and durability can be combined with cheapness.
Although we have described a Tap as constructed with a removable shell to both
the plug and the body, we may apply a removable shell or lining to the body alone,.
using a solid plug, this being more easy to remove and less costly to renew than the
body of the tap.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1- In the construction of Taps for steam, Water, and other fluids, the combination
with the plug of a removable conical working surface or shell, and the combination
with the body, of a removable shell or working surface, for the purpose specified, and
substantially as herein before described and shown.
2-In Taps with solid plugs, the combination with the body of an internal
removable shell or working surface, as hereinbefore described for the purpose
specified.
