We, EDWARD TILEY LAMBERT of Short Street, Lambeth, London, S.E., Civil
Engineer, and EDWIN JAMES WHITE of Overton, Maisemore near Gloucester, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-

it
Our improved tap opens and closes with a quarter turn of a hollow spindle to which
a handle is applied. Within the spindle is a rapid multiple threaded screw;
operates a valve which opens against the flow. The valve spindle at its upper end has
corresponding threads upon it and it has guiding wings between the screw and the
valve, it carries the valve at its lower end. The valve consists of a metal disc faced
with vulcanised fibre or other suitable material and this is held in place upon the disc
by a screw ring provided with lips overlapping the edges of vulcanised fibre. Or in
some cases we employ a coned valve ground into its seat.
The metal valve disc has a hole in the centre in which a screw thread is sometimes
cut. It screws upon the lower end of the spindle.
The disc has a projecting part on its under side which is squared exteriorly to
receive a spanner. By means of the spanner the valve disc is screwed tightly upon
the spindle so as to nip firmly the disc of vulcanized fibre or other material against a
flange formed upon the spindle. The wings on the sides of the spindle engaging with
guiding projections within the shell or body of the tap prevent the spindle from turning
whilst the valve is being screwed up tight. The same guiding projections prevent the
valve turning whilst it is moved by the screw to and from the valve seat. The end of
the spindle projecting below the valve receives a lock nut which is formed with wings
for turning it. The screw thread at the upper end of the spindle is by preference
quadruple; it is of such a pitch that a quarter turn of the screw suffices to remove
the valve the full distance from its seat and as far as the valve is free to move.
.
The water way through the body or shell of the tap is divided into two parts by a
partition through which is the passage which the valve serves to open and close. The
space below the partition cominunicates with the inlet side of the body or shell, and
the part above the partition with the outlet. The valve seat is horizontal; beneath it
the body or shell is open for the insertion of the valve and a screw cap closes this
opening. Above the valve seating the body or shell is open to receive the valve
spindle, and around this opening are flanges for the attachment of the head of the
tap.

The head of the tap consists of a stuffing box and the hollow spindle passes down
through it. This spindle at its upper end carries a handle, and at its lower end it is
flanged beneath the stuffing box to prevent it rising.

COMPLETE SPECIFICATION.
Improvements in Taps or Valves.
We, EDWARD TILEY LAMBERT of Short Street, Lambeth, London, S.E., Civil
Engineer, and EDWIN JAMES WHITE of Overton, Maisemore near Gloucester, Civil
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 :-
This invention has for its object improvements in taps or valves and is applicable
more especially to taps or valves to be used with hot or cold water and steam.
In the annexed drawings Figure 1 is a vertical section of our improved tap or
valve. Figure 2 is a section on the line 2, 2, in Figure 1.
Our improved tap opens and closes with a quarter turn of a hollow spindle a to
which a handle is applied. Within the spindle is a rapid multiple threaded screw a¹;
it operates a valve which opens against the flow. The valve spindle cat its upper end
has corresponding threads c¹ upon it and it has guiding wings c² between the screw
and the valve which it carries at its lower end. The valve consists of a metal disc d
faced with vulcanised fibre e or other suitable material and this is held in place upon
the disc by a screw ring f provided with lips f¹ overlapping the edges of the vul-
canised fibre. Or in some cases we employ a coned valve ground into its seat.
The metal valve disc has a hole in the centre in which a screw thread is some-
times cut. It screws upon the lower end of the spindle c.
The disc has a projecting part d¹ on its under side which is squared exteriorly to
receive a spanner. By means of the spanner the valve disc d is screwed tightly
upon the spindle so as to nip firmly the disc of vulcanized fibre or other material e
against a flange c³ formed upon the spindle. The wings c² on the sides of the spindle
engaging with guiding projections g g within the shell or body g of the tap prevent
the spindle from turning whilst the valve is being screwed up tight. The same
guiding projections prevent the valve turning whilst it is moved by the screw a¹ to
and from the valve seat. The end of the spindle projecting below the valve receives
a lock nut h which is formed with wings h¹ for turning it. The screw thread c' at the
upper end of the spindle is by preference quadruple; it is of such a pitch that a
quarter turn of the screw a¹ suffices to remove the valve the full distance from its
seat and as far as the valve is free to move.
The water way through the body or shell of the tap is divided into two parts by a
partition g through which is the passage which the valve serves to open and close.
The space below the partition communicates with the inlet side of the body or shell,
and the part above the partition with the outlet. The valve seat is horizontal
beneath it the body or shell is open for the insertion of the valve and a screw cap i
closes this opening. Above the valve seating the body or shell g is open to receive
the valve spindle c, and around this opening are flanges 9³ g³ for the attachment of
the head of the tap.
The head of the tap consists of a stuffing box k and the hollow spindle a passes
down through it. This spindle at its upper end carries a handle, and at its lower end
at as it is flanged beneath the stuffing box k to prevent it rising.
The head is flanged at around its lower edge and this flange abuts upon the
flange 93 at the top of the body and the two are held together by tap screws. Or
the head may screw on to the body of the tap.

page_text: A loose washer surrounds the valve spindle and this is received into a recess
contained partly in the top face of the body and partly in the under surface of
the head.
Upon this washer the flanged lower end of the hollow screw spindle a abuts, and
this abutment prevents the hollow spindle descending so that, when it is turned a
quarter round in one direction it lifts the valve to its seat whilst a quarter turn in the
opposite direction opens the valve to the full extent.
Figure 3 is a vertical section and Figure 4 is an horizontal section of a tap or
valve constructed in accordance with our invention. In these figures the head k is
shewn to be screwed on to the body g in place of being fixed by tap screws as is
intended in the Figures 1 and 2.
Figure 5 is a vertical section of a tap or valve similar to that shewn by the
Figures 3 and 4 but in lieu of the outlet spout it is provided with a socket into which
a pipe may be screwed.
Sometimes in place of a stuffing box in the head of the tap we provide a flexible
diaphragm through which the valve spindle passes. This arrangement is shown in
Figure 6 which is a vertical section. The middle of the diaphragm is attached to the
spindle; it is nipped between the flange c and the ring which is screwed on to the
spindle and the diaphragm is held by its edges between the flanges 93 on the body k¹
and on the head of the tap.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. A tap or valve substantially as herein described in which the opening is against
the flow and is effected by a quarter turn of a rapid multiple screw within a hollow
spindle as herein set forth.
2. In a tap or valve the combination of parts a, c, d, e, k and
described.

3. Taps or valves substantially as represented by the drawings annexed.
