PROVISIONAL SPECIFICATION.
Improvements in Taps for Liquids.
I, CHARLES HORTON of 43 Union Lane Sheffield, in the County of York,
Brass Founder, do hereby declare the nature of my invention to be as follows:-
This invention of improvements in taps for water and other liquids, has for its
object to dispense with the leather washer which so rapidly becomes worn and
causes the tap to leak, and requires replacing.
I propose in the construction of an ordinary water tap, for example, to make the
body of the usual shape, with the interior so arranged that when the cap is
removed, I can insert a detached seating and valve of peculiar construction, here-
after described.
In the horizontal part of the division wall inside the tap, and directly under the
opening (which is afterwards closed by the cap), is a circular opening of con-
siderable size, preferably provided with a screw thread. The valve seat consists
of a disc of metal, to fit and screw into the circular opening before mentioned, and
having a depending bell shaped part, open at the top and the bottom, and forming
the water way.
The valve is also bell shaped, and fits inside the bell shaped seat; it is provided
with a spindle which passes through the cap, and is raised and lowered by the
usual screw movement of the spindle.
I prefer to stamp the bell shaped parts of the valve and its seat, so that they
may be accurately formed and water-tight, without the cost of fitting, but I do not
bind myself to make them in this manner.

COMPLETE SPECIFICATION.
Improvements in Taps for Liquids.
I, CHARLES HORTON of 43 Union Lane, Sheffield in the County of York,
Brass Founder, 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 :-
This invention of improvements in taps for water and other liquids, has for its
object to dispense with the leather washer connected with the valve and which so
rapidly becomes worn, and requires replacing.
I have illustrated my invention in the annexed sheet of drawings, in which
similar letters of reference indicate similar parts in any of the figures.
Fig. 1, is an elevation of a tap made according to my invention, the chief parts
being in section.
Fig. 2, views of the valve seating.
Fig. 3, the valve.
Fig. 4, modification of valve.
I propose in the construction of an ordinary screw down tap, such as shown in
the drawings for example, to retain the usual shape of the body A, but to do away
with the fixed or solid seating as used in ordinary taps.
Instead of a fixed seating I use a removable seating B, this is screwed into the
circular opening or water way formed by the walls or ring of metal C, and C¹, and
is concentric with the valve spindle D.

page_text: The valve seating is of such a diameter that it can be inserted through the
opening in the top of the tap before the cap E, is screwed into position, but it may
if desired be inserted by means of a removable cap at F, and the seating may be
fixed in position otherwise than by a screw thread.
The facing G, of the seating upon which the valve H, rests, is made on the
underside, and the two lugs I, are to enable it to be screwed into position by a
suitable tool.
The valve is formed upon the end of the screw spindle D, and can be opened
and closed upon the seating by turning the handle K, fixed upon the spindle D.
Instead of being made solid, the valve H, may be made hollow or bell shaped, as
shown in Fig. 4, by stamping it out of sheet metal, so as to avoid machining;
the seat may also be made by similarly stamping it in dies from sheet metal,
and attached to a screw threaded ring to fit into a corresponding screwed part C
and C
It will be evident that the pressure of water will tend to keep the face of the
valve, in close contact with the face of the seating, and thus prevent leakage.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the is or may be carried into practice, I declare that
what I claim is :-
1 In the construction of taps for liquids, the removable seating B, with the face
for the valve on its lower edge, in combination with a. corresponding valve H,
fitting thereon, arranged as hereinbefore described and illustrated.
2 In the construction of taps for liquids, a valve seat stamped out of sheet
metal, and a bell shaped valve similarly formed, and fixed in the tap so that the
flow of water would tend to close the valve, substantially as hereinbefore described,
and illustrated.
