THOMAS GARFORTH RHODES Albert Terrace, Kirkstall, Leeds Engineer,
RAYMOND GAUNT Engineer The Mount Stanningley Leeds. We do hereby
declare the nature of this invention to be as follows:-
This invention has for its object, improvements in the construction of wate
taps, valves and the like.
(1) The cup shaped rubber M or other material in Specification No. 786, 1895,
may be provided with a metallic ring or frame for containing the cup shaped
rubber M, together with a second piece of rubber, the object being to retain the
two parts, and also to prevent the rubber from fraying, the second portion of the
cup shaped rubber is to enable this part which forms the valve face to be readily
renewed.
The cup shaped rubber, has a spherical or other form of end, and is smaller
than the cup M2 (in Specification No. 786, 1895) so that it always rights itself to
the valve face.
(2) An arrangement of stop or bit tap provided with a leather, for preventing
the escape of the water, in place of a packing gland, also a valve arranged to or in
connection with the retaining ring, of the said leather, the leather and valve are
connected with a screw cap, fitting the body of the stop or bit tap, a flexible
rubber or other buffer is interposed between the valve and screw cap.
(3) An improved form of equilibrium tap or valve, consisting of two flexible
leathers, or its equivalent, arranged on a spindle, and working in a cylinder or
barrel, such barrel is also surrounded by another cylinder, the water enters the
said barrel through the outer cylinder by means of a hole, in the barrel, and
between the two leathers, the lower end of the barrel forms the delivery by another
arrangement of holes, communicating with the outer cylinder. When one of the
leathers on the spindle slides over the said holes the supply is cut off, and at the
same time, the pressure on all parts of the leather is the same.
(4) Another modification of the above is to make the two leathers and the barrel
of different diameters and connect the two leathers to a spindle by this means a
self closing tap may be formed. Or in place of the differential diameters, a spring
may be substituted.
(5) Another modification consists in forming the barrel with another set of
holes, which in turn communicates with another chamber, in the outer cylinder,
also the spindle connecting the two leathers, is made hollow and communicates
with the said set of holes, thus the valve becomes one by which water under
pressure may be used and exhausted.

The cup shaped rubber M shown in our prior Patent No. 786 may be provided
with a metallic ring or frame A for holding the said cup shaped rubber M together
with a second piece of rubber B, the object being to retain the two parts M and B
and also to prevent the rubber from fraying, the second portion of the cup shaped
rubber is to enable this part, which forms the valve face to be readily renewed by
unscrewing the top part of the metallic frame A¹ from the bottom part A of
same, the metallic frame is dovetailed so as to get a; better grip of the rubber M
and B.
The cup shaped rubber M has a spherical end so that it always rights itself to
the valve face.
In
The cup shaped rubber M is smaller than and is loose within the cup M', which
latter is pivotted to the ball lever; the cup M has faces or projections, on jits
outside leaving openings for the water between it and the body of the tap.
some cases a metallic frame A2 is used to cover up the cup shaped rubber (see
Fig. 3) and prevent its wearing or fraying. A bib pipe C is shown in Fig. 2 for
silently carrying the water to the cistern, the outer cup M' fitting the main body
of the tap, the water must pass by way of the bib pipe.
A stop valve E may be used in connection with my improved ball tap (see Fig. 4)
for. use when repairing I employ a leather valve face E with a rubber back or
buffer F carried in a metallic retaining ring G with a ring leather H in place of a
packing gland, the screw cap J fits the body of the tap.
Our arrangement of stop or bib tap is shown at Fig. 5 and is provided with a
ring leather H for preventing the escape of the water in place of a packing gland,
also a valve E arranged to or in connection with the retaining ring G of the said
leather H, the leather and the valve are connected with a screw cap J fitting the

page_text: body K of the stop or bib tap, a flexible rubber or other buffer F is interposed
between the valve and the screw cap J. In the bib taps in place of a retaining
ring G valve E and rubber F the cup shaped rubber M may be employed.
Our improved form of equilibrium tap or valve is applied to ball taps, and bib
taps (see Figs. 6 and 7) and consists of two flexible leathers H H or the equivalent,.
arranged on a spindle L and working in a cylinder or barrel N such barrel is also
surrounded by another cylinder P, the water enters the said barrel through the
outer cylinder P by means of a hole R in the barrel N, and between the
two leathers H H, the lower end N¹ of the barrel forms the delivery by
another arrangement of a series of holes S S communicating with the outer
cylinder P.
When one of the leathers on the spindle slides over the said holes, the supply
is cut off, and at the same time the pressure on all parts of the leather is the
same.
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. The cup shaped or spherical self adjusting rubber valve M, with its top-
part B, renewable by means of metallic frames A and A' with or without the
extended metallic cover A² substantially as shown and described.
2. The combination of the self adjusting valve M, with renewable top B, working
within the outer cup M¹, provided with water passages within the body of the tap,
and pivotted to the ball lever substantially as shown and described.
3. In bib and ball taps the spherical self adjusting valve M, in combination
with a stop valve E, with leather face and india-rubber buffer F, retaining ring G,.
ring leather H, and screw cap J, substantially as shown and described.
4. In ball taps the equilibrium valve with double ring leather HH, upon
spindle L, working within cylinder N, having hole R, outer cylinder P, and
holes S S, as and for the purposes substantially as shown and described.
5. In bib taps the equilibrium valve with double ring leathers H H upon
spindle L, working within the cylinder N, having hole R, and holes S S, with
outer cylinder P, and screw cap J, as and for the purposes substantially as shown.
and described.
