"Banister Smith" of Eversley
I, JOHN BANISTER SMITH commonly known as
Logo Victoria Road Putnoy Surrey Surveyor, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to combine the advantages of a full way tap or valve
with simplicity of construction and easy prompt and certain action.
My invention will be found particularly applicable to screw down taps which hitherto
have proved very inconvenient and troublesome from the amount of screwing and
unscrewing required when operating the tap as by my invention the supply can be
effectually turned on or shut off by a single quarter turn of the tap more or less.
My invention consists in forming two or more orifices or apertures laterally or
otherwise in the barrel of a tap and forming a screw thread round the outer surface
of such barrel and also one or more grooves which serve as a channel or channels
of communication between such orifices.
An annular recess or chamber is formed round the tap body or screw cap and
leads into the nozzle of the tap-This annular chamber allows room for the water
to circulate freely when the tap is either partly or fully open and so relieves the
pressure thereof on the splash washer with which in the case of a bib or other
draw off tap the tap is fitted in order to prevent leakage-Such orifice or orifices
groove or grooves and annular chamber together form a series of outlets through
which by giving the tap a single quarter turn more or less. The water flows out
freely in a full current while by giving the tap a single quarter turn more or less in
the reverse direction the supply is at once completely shut off.
My invention is readily applicable to bib taps, ball taps, stop cocks, steam taps,
screw down taps bath taps and other taps for drawing off liquids.

Improvements in Bib Taps, Ball Taps, Steam and other Taps.
1, JOHN BANISTER SMITH, commonly known as "Banister Smith," of Eversley
Lodge, Victoria Road, Putney, Surrey Surveyor, 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 :-
The object of this invention is to combine in a bib, ball, steam, or other tap,
the advantages of a full way tap or valve with simplicity of construction, and easy,
prompt, and certain action-My invention is particularly applicable to screw down
taps, which hitherto have proved very inconvenient and troublesome, owing to the
amount of unscrewing and screwing required when operating the same; as by my
invention the supply can be effectually turned on or shut off by a quarter turn of the
tap more or less.
The letters of reference occurring in the following description of my invention,
refer to corresponding letters in the accompanying drawings, wherein Fig. 1, is a
sectional view of a bib tap made according to my invention, and Fig. 2 is a transverse
section of the barrel of such tap taken on the line A. B. Fig. 1-Fig. 3 is a detail
view shewing an enlarged section of the groove e, and the way in which the cap c
impinges on the washer."
The primary feature of my invention consists in making two or more holes or

page_text: apertures a, either laterally or otherwise, in the barrel of the tap-Such barrel may
either have a screw thread cut thereon, to allow of its screwing into and working
to-and-fro with a screw motion in a threaded cap c-Or the screw threads may be
dispensed with, and such barrel may work to and fro in the cap with a sliding
motion.
The second feature of my invention consists in forming a groove or channel e round
the barrel, into which groove or channel the water or other liquid flows through the
..holes or apertures a, and from thence, immediately the tap is opened, into the annular
..chamber presently mentioned-To do this I proceed as follows:-If the barrel and
cap are screw threaded I turn off one or more threads of the screw either on the barrel,
or on the cap, or on both,-(as shewn at Figs. 1, and 3)-and thus make.the groove
'or channel If however the barrel and cap are made to work in each other with a
sliding motion I cast such groove or channel either on the barrel, or on the cap, or on
"both.
The third feature of my invention consists in forming around the tap body, or round
a cap fitted to the barrel of the tap, an annular chamber which leads to the nozzle i,
and allows the water or other liquid to circulate freely when the tap is open, thus
avoiding any undue pressure on the tap, and so preventing leakage.
The apertures a,channel e, and annular chamber f, form a series of outlets through
which the liquid flows out freely, by giving the tap a quarter turn more or less;
while by turning it in the reverse direction the supply is at once shut off.
I would here point out that the primary feature of my invention may be used either
separately, or in combination with the subsidiary features thereof, thus in some cases
it may be found sufficient merely to make the apertures in the barrel in the manner
hereinbefore described, while in others such apertures may be combined with one, or
more, or all of the remaining features of my invention, as may be found desirable-
'My invention is readily applicable to all kinds of taps.
Having now particularly described and ascertained the nature of my said inven-.
tion and in what manner the same is to be performed 1 declare that what I
claim.is.
1. In a bib, ball, steam, or other tap, a barrel having two or more holes or apertures
formed therein, all substantially in the manner and for the purpose herein before
described and shewn..
2. In a bib, ball, steam, or other tap, the combination of 'a barrel having two or
more holes or apertures formed therein, with a cap wherein it works with either a screw
or sliding motion, all substantially as hereinbefore described and shewn.
3. Forming a groove or channel round such barrel, all substantially in. the manner,
and for the purpose herein before described and shewn.
4. In a bib, ball, steam, or other tap, forming an annular chamber round the tap
"body, or round a cap fitted to the barrel of the tap, all substantially in the manner and
'for the purpose herein before described and shown.
5. In a bib, ball, steam, or other tap, the use of the primary feature of my invention
as hereinbefore specified, either separately, or in combination with one, or more, or all
of the subsidiary features thereof, all substantially as hereinbefore described.
