Improvements in Compound Taps or Cocks.
We, HENRY COLe Willmott 23 Leighton Terrace, Kentish Town N.W. Urn
Manufacturer, GEORGE GILLETT 314 Camden Road N.W. Gentleman, and CHARLES
EDWARD FRANK 11 St. Johns Road, Clifton, Bristol, Science teacher, do hereby
declare the nature of this invention to be as follows
Our invention has reference to, and is based upon the Specification of the invention
of Henry Cole Willmott dated 10th August 1887 No. 10,701 and is devised with the
object of allowing of the admixture in taps or cocks, and delivery therefrom of two
or more dissimilar fluids, in a simple, efficient and reliable manner, so as to ensure,
that, by the means hereinafter described according to our invention, two or more
dissimilar fluids may be drawn off in definite, predetermined proportions.
The device or appliance in accordance with our invention consists of a tap or cock,
provided, in addition to the ordinary horizontal inlet and outlet apertures, with one or
more branches, each connected with a different reservoir or receptacle for containing
the fluids to be supplied through our improved tap.
The plug of the tap or cock is provided with a movable collar formed with a series
of slots or apertures to correspond with the number of branches, and of such different
areas as to allow of the different fluids passing into and from the tap or cock in definite
proportions relatively to each other.
As illustrative of our invention we have taken the case of "two-way" taps or cocks,
and in the arrangement thereof proceed as follows:-
We form upon the upper part of the body of the tap or cock, at right angles, or at
any other angle thereto, a short branch provided with a screw union, to allow of the
attachment to said short branch of a suitable tube or pipe, which latter would be in
connection with a reservoir containing one of the dissimilar fluids above referred
to, the body of the tap or cock being connected to a receptacle containing the
other dissimilar fluid.
Within the body of the tap or cock takes a plug, having two ways or passages of
different areas, the larger of which is preferably rectangular, and corresponds with
the inlet and outlet apertures of the tap or cock aforesaid. The smaller way or
passage is formed in a diagonal direction relatively to the larger way, with which
latter it forms a junction, the upper opening being in a position corresponding to the
opening of the small branch above mentioned when the plug is so turned as to allow
of the flow of the fluids. The outer end of the plug aforesaid is narrowed to take a
flanged collar which is capable of free movement thereon, and bears against a shoulder
formed by the enlarged tapered inner end thereof. Upon said collar are a number
of narrow slots or perforations, the area of each of which is in direct proportion
relatively to the area of the larger aperture in the plug. The position of said slots
relatively to the smaller aperture of the plug is such, that upon turning the flanged
collar, one or other of the slots aforesaid may be interposed directly between the
small branch on the body of the tap or cock, and the smaller way or passage above
referred to, thus ensuring an admixture of two dissimilar fluids in definite proportions
or, if desired one fluid'only may be delivered from the tap or cock, by turning the collar
aforesaid, so as to close the smaller aperture in the plug.
In order to secure the flanged collar above described in any desired position, a thumb
screw may be employed, which, passing through a tapped hole in the front of the handle,
would take into slots formed in the periphery of the flange of the collar, or into
recesses formed in the face thereof; or, if desired, said flanged collar may be secured
by means of a moveable rod arranged within the handle of the tap or cock, the lower

page_text: end of which takes into the notches above described upon the outer periphery of the
flange said rod being retained in the notches by the tension of a spiral spring or
equivalent device arranged within the chambered handle.

Improvements in Compound Taps or Cocks.
We, HENRY COLE WILLMOTT of 23 Leigton Terrace, Kentish Town N.W. Urn
Manufacturer, and GEORGE GILLETT of 311 Camden Road N.W. Gentleman, and
CHARLES EDWARD FRANK 11 St. Johns Road, Clifton, Bristol, Science Teacher,
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:
Our Invention has reference to, and is based upon the Specification of the Invention
of Henry Cole Willmott dated 10th August 1887 No. 10,701 and is devised with the
object of allowing of the admixture in taps or cocks, and delivery therefrom of two
or more dissimilar fluids, in a simple, efficient and reliable manner, so as to ensure,
that, by the means hereinafter described according to our Invention, two or more
dissimilar fluids may be drawn off in definite, predetermined proportions.
The device or appliance in accordance with our Invention consists of a tap or
cock, provided, in addition to the ordinary horizontal inlet and outlet apertures, with
one or more branches, each connected with a different reservoir or receptacle for
containing the fluids to be supplied through our improved tap.
The plug of the tap or cock is provided with a moveable collar formed with a series
of slots or apertures to correspond with the number of branches, and of such different
areas as to allow of the different fluids passing into and from the tap or cock in definite
proportions relatively to each other.
To render the explanation of our Improvements herein given more clear we have
appended the accompanying sheet of Drawings and will now describe the same having
reference to those drawings.
As illustrative of our invention we have taken the case of "two way" taps or cocks,
and in the arrangement thereof proceed as follows.
We form upon the upper part of the body A Figure 7 of the tap or cock at right
angles or at any other suitable angle there-to a short branch B provided with a screw
union a to allow of the attachment thereto of a suitable tube or pipe which latter
would be in connection with a reservoir containing one of the dissimilar fluids above
referred to, the body of the tap or cock being connected to a receptacle containing the
other dissimilar fluid.
Within the body of the tap or cock A takes a plug D Figures 1 and 2 having two
ways or passages b and c of different areas the larger of which is preferably
rectangular and corresponds with the inlet and outlet aperture of the tap or cock
aforesaid. The smaller way or passage c is formed in a diagonal direction relative to
the larger way b, with which latter it forms a junction the upper opening being in a
position corresponding to the opening of the small branch above mentioned when the
plug is so turned as to allow of the flow of the fluids. The outer end of the aforesaid
is narrowed to take a flanged collar C which is capable of free movement thereon, and
bears against a shoulder d formed by the enlarged tapered inuer end thereof. Upon
said collar C are a number of narrow slots e, f the area of each of which is in such
a proportion to the area of the larger aperture, that only a certain proportion of
the quantity of fluid which passes through the larger aperture can pass through e and f
respectively. The position of said slots e and f relatively to the smaller aperture cof
the plug is such that upon turning the flanged collar C one or other of the slots e or
f

page_text: aforesaid may be interposed directly between the small branch B on the body A of the
tap or cock, and the smaller way or passage c above referred to, thus ensuring an
admixture of two dissimilar fluids in definite proportions, or, if desired one fluid only
may be delivered from the tap or cock by turning the collar C aforesaid so as to close
the smaller aperture e in the plug, and open one communication only either through
large aperture 6 by means of which one of the dissimilar fluids alone is allowed to
escape, or, another communication from branch B through passage g to opening h by
which means the other dissimilar fluid is allowed to escape.
In order to secure the flanged collar C above described in any desired position a
thumb screw i may be employed, which passing through a tapped hole in the front,
of the handle, would take into slots formed in the periphery of the flange of the
collars, or into a recess j formed in the face thereof, or, if desired said flanged
collar may be secured by means a moveable rod arranged within the handle of
the tap or cock the lower end of which takes into the notches above described
upon the outer periphery of the flange said rod being retained in the notches
by the tension of a spiral spring or equivalent device arranged within the chambered
handle.
Or we may form, as shown in Figures 5, 6, and 7 the plug E of the tap or cock in
one piece, without the flanged collar as previously described; in this case the arrange-
ment of the branch B with its screw union a and the passage in the plug is the same
as previously described plug. E has in addition to the large aperture 6 two small
apertures & and 1 of different areas the proportion of areas of said apertures to the
proportion of the area of 6 being arranged in a manner similar to that which applies
in reference to the areas of e and herein before described; these apertures k and l
communicate with each other and with aperture b, and by turning the plug E as shown
in the sectional views.
Figure 7 we draw off. one fluid through 6 and a definite proportion of a dissimlar
liquid from the receptacle connected to branch B by means of passages 7 which
is connected to b or by turning the plug E into certain positions we may by means of
apertures b and k respectively draw off at two operations each of the dissimilar fluids
separately.
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 :-
First. The improved compound tap or cock for drawing off at one and the
same time two dissimilar fluids, and allowing of the mixture and discharge of the
same therefrom in predetermined proportions substantially as herein set forth.
Second. In compound taps such as those refeered to in the preceding claim the
arrangement of ways or passages in order that each of the dissimilar fluids-contained
in the receptacle to which such taps or cocks are attached-may be withdrawn at will,
separately; substantially as and for the purpose specified.
