PROVISIONAL SPECIFICATION.
Improvements in the Construction of Cocks and Taps for Water and
other Liquids.
I, JOHN OBADIAH BROOKE, of 9 Cross Street, Northgate, Wakefield, in the
County of York, Plumber and Sanitary Engineer, do hereby declare the nature of
this invention to be as follows:-
According to my said improvements the body or lower part of the tap (forming
the "inlet connection) is made or formed with a seat or flat surface, so that a
washer of leather (which is separate from the valve) or other suitable material,
carried or fitted thercon, forms the seat against which the valve is screwed or
pressed down; the said washer so bearing upon the said metal seat that the water
or other liquid does not come in contact therewith, thus preventing "pitting
injury to the metal which forms what is usually known or may be described as the
"seat" of the tap.
"
or
The said metal seat may be formed with or without a lip or projecting rim
around the hole or orifice for the water.
The valve is preferably made in one piece and its under surface or the surface
coming in contact with the washer is preferably formed concave, but may be convex,
flat, or other suitable shape.
The body of the tap is formed with the "inlet" attached to the lower part, and
the "outlet "attached to the upper part, in such a manner that the seat or face
against which the washer of leather or other suitable material fits, can be examined
and smoothed if necessary at any time, without removing the inlet part from its
position.
Further, in the top part of the tap I provide a removable bush which has a
threaded hole for the screwed spindle to work in.

COMPLETE SPECIFICATION.
Improvements in the Construction of Cocks and Taps for Water and
other Liquids.
I, JOHN OBADIAH BROOKE, of 9 Cross Street, Northgate, Wakefield, in the
County of York, Plumber and Sanitary Engineer, 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 :-
My invention relates to certain improvements in the construction of cocks and

page_text: Fig. 5. is a sectional elevation through the line D, D, (see Fig. 4) of interior
casing showing the water ways.
Fig. 6. is a sectional elevation of tap with "inlet" attached to lower part and
"outlet
attached to top part of tap for facilitating repairing of the valve seating.
Fig. 7. is a sectional elevation of tap showing screwed bush combined with valve,
and dispensing with the inner casing C.
According to my said improvements the body or lower part E of the tap forming
the inlet connection F) is made or formed with a seat or flat surface G so that
a washer of leather H, (which is separate from the valve) or other suitable material
carried or fitted thereon forms the seat against which the valve J is screwed or
pressed down the said washer so bearing upon the said metal seat, that the water
or other liquid does not come in contact therewith, thus preventing "pitting
injury to the metal which forms what is usually known or may be described as the
seat of the tap.

or
The said metal seat may be formed with or without a lip or projecting rim
around the hole or orifice K for the water but preferably with such lip or
projection.
The valve is preferably made in one piece, and its under surface or the surface
coming in contact with the washer may be formed concave, convex, flat or other
suitable shape.
I prefer however, to make the said surface concave, so that the edges of the
valve J, which may be slightly rounded shall thoroughly press upon the washer H
of the seating G, and so effectually shut off the water.
In Figure 1 the screwed spindle M is shown screwing into the interior casing C,
in the top or neck of which is screwed the stuffing box N. The said interior
casing C is formed with water ways O.
In Figure 3 the spindle M is provided with a removable screwed end M', which
engages with and works in the screwed hole of the removable bush P at the base of
which is the valve J, so that when the threads of such end and those of the bush P
are worn they (the bushes) can be readily replaced or renewed. The stuffing
box N screws into the top or neck of the interior casing C as in Fig. 1.
For preventing the interior casing C and removable bush P from turning round
when applied in the tap, the interior casing C is provided with ribs R which fit
into grooves S in the tap body, and the removable bush P is provided with similar
ribs R which fit into grooves S in the said inner casing C, see Figs. 2 and 4.
The body of the tap is formed with the "inlet" attached to the lower part and
the "outlet" attached to the upper part in such a manner that the seat or face
against which the washer of leather or other suitable material fits, can be examined
and smoothed if necessary at any time without removing the "inlet "
part from its
position, see Fig. 6. But for the purpose aforesaid, I prefer to construct the tap as
shown in Figs. 1 and 3 of the drawings annexed, where the "inlet and outlet
are constructed together and provided with a screwed or movable cap T, and a
packing U of leather or other suitable material together with a packing or washer
of metal V upon the leather or other suitable material.
::
"
On removing the said screwed cap T, the screwed spindle, valve, interior casing
and parts connected therewith, can be bodily removed and the seating or washer of
the tap readily attended to.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
-
1. The construction of cocks and taps having seatings G with washers H fitted
thereon around orifices K for the flow of liquid from the inlet to the outlet con-
nections, and upon which washers the valves J are brought to bear substantially as
and for the purposes such as shown and described.
2. The construction of cocks and taps having removable threaded bushes P for
the removable screwed ends M' of the spindles M to work in, in combination with

page_text: washers H, seatings G and valves J, with or without interior casings + C, and
which said bushes P may be combined with valves J or not, as and for the purposes
such as shown and described.
3. In cocks and taps the employment of valves the under surfaces of which are
concave or hollowed out in combination with the construction of valve seating such
as shown and described.
4. In cocks and taps the construction of valves in combination with the con-
struction of valve seating as and for the purposes such as shown' and described..
5. The improved construction of cocks and taps such as shown and described..
6. The construction of cocks and taps so that the seatings against which washers
of leather or other suitable material fit can be examined and the working parts
renewed or repaired if necessary, without removing the "inlet" parts from their
positions substantially as shown and described.
