COMPLETE SPECIFICATION.
Improvements connected with Water and like Taps.
We, ROBERT BELL, Clerk, of 2 Whitburn Terrace, South Shields, and
WILLIAM THOMAS HALL, Schoolmaster, of 1 Whitburn Terrace, South Shields,
do bereby 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 object, the construction of water and like taps in which
plugs are used to open and to close the flow through passage.
The invention is applicable to ordinary draw off water taps for domestic
purposes, for baths, for cistern ball taps, or for spirits or oil, alight modifications
being made to suit the particular purpose intended.
The manner of carrying our invention into practice is represented on the annexed
sheet of drawings in which
Figure 1 is a sectional elevation of a combined screw down tap with a long or
deep plug for vertical action.
Figuro 2 sectional elevation of a bath tap with short plug having screw down
action for closing purposes.
Figure 3 sectional elevation of a screw up action for closing purposes.
Figure 4 section of ball cistern tap with plain drop action for iulet of water and
with a deflector for water flowing over at narrow end.
Figure 5 sectional elevation of spirit, oil, or other tap in which the plug can be
raised for flow by pressure on hand lover and returned by an enclosed spring.
According to Figure 1, the plug A is of long conical shape to fit within a
correspondingly shaped internally made barrel B, said plug is hollow and loosely
fitted on a stem C as in dotted lines, it is secured at bottom by a washer and
pin D.
The upper part of the stem is screw threaded at E for operation within the screw
collar F which is screwed into the shoulder G of the barrel B.
This collar is in this view provided with a cap H for lubricating substance for
ease of turning the handle I.
The plug is here shown in an open condition and its annular groove J presents
a full and free flow of water from the neck K to the outlet L and when the handle
is screwed down the annular channel J becomes buried just below the rim a, a, the
full portion of the plug M shutting off the flow passage.
According to Figure 2, the long stem C is dispensed with; and a neck N on the
plug A is held to the stem C by transverse pins b, b, which pass in an annular
groove of said stem, as indicated.
The plug A of this tap is also loosely mounted and bas free action to adjust
itself like the plug shown at Figure 1 to obtain its bite or bearing in the barrel B.
The plug is much shorter than that shown at Figure 1 and has a free lift when the
handle is turned for upward flow from the inlet K to the outlet L. We have
shown this tap as fitted above a bath P and secured to the bath ulate or surface
frame board by the lock nut R. S is the union for connection of supply pipe.
According to Figure 3, the plug A is drawn upwards to close the passage in the
barrel B, said plug being inserted from the bottom and connected to the short
stem C in a ball and socket joint C or it may be in a similar manner as that
shown at Figure 2.

page_text: At Figure. 4, the plug A is free to drop under the action of the ball T within
the barrel B as the water lowers in the cistern to which the tap is affixed for
supply, the water then flowing both downwardly and upwardly to refill the
cistern.
The upflow impinges against the deflector U and falls to commingle with the
down flow. The deflector U is of inverted cup shape to prevent undue
splashing.
According to Figure 5, the plug A is a long one as at Figure 1, and instead of
the handle and stem having a rotative motion they and the valve plug have a lift
motion by a pressure on the lever V which for convenience is used in connection
with a branch W, said stem C and plug A being returnable by the spring X
which has a position between the stem disc e and the barrel neok collar F.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The improvements conuented with water and like taps as hereinbefore set forth
and consisting of a conical plug A loosely fitted and having a lift motion from or
with a stem for self location within the conical portion of the tap barrel, as and
in the manner shown.
