PROVISIONAL SPECIFICATION.
Improvements in Taps.
We, JOHN HARRISON WILSON of 114 Eldon Street Keighley in the County of
York, Tin Plate Worker, and THOMAS PRATT of Oakworth Road Keighley aforesaid,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows, that is to say :-
It relates to improvements in ball-taps and consists of arranging and constructing
these taps in such a manner that they shall operate more efficiently, and be more
durable than heretofore.
This we attain by forming the barrel or tubular part of the tap so that it will
receive a suitably shaped washer of India rubber (caoutchouc) which forms the
seating for the ball. Said tubular part of the tap is also formed to receive an
appropriately shaped holder which we preferably attach to the screwed plug covering
the opening through which said holder and ball are inserted:
This holder is so formed that the ball is held in suitable proximity with its seating
to enable the pressure of the fluid to press it into connection therewith as will be
well understood, same being required to be forced against the pressure in order to
open said tap, by which means balls made either of glass or vulcanite may be
employed and still the liability of breakages of the said glass-balls by fluctuation in
pressure of said fluid or other causes, may be avoided.
We make use of glass-balls when the taps are to be used where there is considerable
fluid pressure, and vulcanite where the pressure would not be sufficient to press as
above described a ball of greater specific gravity than that of the fluid itself.

COMPLETE SPECIFICATION.
Improvements in Taps.
We, JOHN HARRISON WILSON of Number 114 Eldon Street Keighley in the
County of York, Tin Plate-Worker, and THOMAS PRATT of Oakworth Road,
Keighley aforesaid, Mechanical 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, that is to say:-
It consists of improvements in the construction and arrangement of the parts
forming a tap, in such a manner that said taps are made to operate more efficiently
and to be more durable than heretofore, and in order that our said invention may be
more readily understood we have hereunto appended sheets of drawings illustrative
thereof, to which, by figures and letters, reference is made in the following
description.
.
Fig. 1 is a side view shewing the formation of a tap constructed in accordance
with this invention, fig. 2 is a part sectional side view of said tap shewing the
construction or formation and general arrangement of parts, while fig. 3, is a similar
view to fig. 2 but illustrates a modification in the formation of certain parts as
hereinafter described...
Similar letters of reference indicate similar parts throughout the several views.
The object of our invention is attained by forming the barrel or tubular part a so
that it will receive a suitably shaped ring or washer of India Rubber (Caoutchouc)

page_text: or other suitable material or substance 6 which is to form the seating for the ball (or
valve) c. The tubular part a is also forined to receive an appropriately shaped-
holder d d', which might be formed in one piece, and made to extend from the
screwed plug e (to which it might be attached if desired) to the ring b and so hold
the said ring b in position against the rim or flange at formed within the part a, the
said holder d d¹ having a flange f formed within it to keep the ball c in position so
that the liability of breakages by any fluctuation in the pressure of the fluid in
connection with which said tap may be used is entirely avoided, and the said ball c is
made to act in the desired manner in concert with the screw y which is operated in
the well known manner by the thumb-and-finger piece'g'. Or this holder d d might
be made in two parts as shown and a portion of the Hange f.may be formed by the
insertion between the parts d and d of a ring of India-rubber or other suitable
material by these means the ball or tap is made to have double-action as hereinafter
described.
The holder d d or holders d and dis or are so formed by being of tubular shape
to fit within the part a, and having the flange and the openings & formed thereon
and therein, that the ball c is held in suitablo proximity with its seating, to enable
"the pressure of the fluid passing through said openings k k somewhat in the direction
as shewn by arrows b, to force it into connection therewith as indicated by broken
lines fig. 2 and as will be well understood, the said ball c being required to be forced
against the pressure of said fluid by means of the screw g in order to open a passage
for same.
We make use of balls c constructed of glass or metal when the taps are to be used
where there is considerable fluid pressure, and of vulcanite where the pressure
would not be sufficient to force, as above described, a ball of greater specific gravity
than that of the fluid. itself, however as glass or metal is the most desirable substance
of which to construct these balls c by the employment of the supplementary seating g²
'above described we are enabled to use balls so constructed regardless of the fluid
pressure, since if said pressure is not sufficient to force the ball c against the seating b
by rotating the screw so that it will move and press said ball c against its
supplementary seating the object desired will be attained.
Instead of the ball é being employed a valve m (see fig. 3) somewhat of the shape
of a double cone might be used, in which case the outer end of the screw g might
be made to enter an opening made therein as shewn in broken lines in order to retain
same in proper position for effecting the object desired..
our said
Having now particularly described and ascertained the nature of
Invention, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A tap formed and constructed substantially as herein described, the same
consisting of a tubular part a a holder d d' or holders d and d¹ formed as shewn,
seatings 6 and 92, ball c, screw. g and plug e in combination all of which are arranged
to operate as set forth.
2. The part a formed as shown, seatings b and g³ valve c or m, holders d and d¹,
.plug e and screw g, in combination, the same being formed, constructed and arranged
to operate substantially as specified.
