Improvements relating to Valves for Taps and Pipes.
I, HENRY RUSSELL of Crown Brass Works, Falkirk in the County of Stirling
North Britain Engineer & Brass Founder do hereby declare the nature of this
invention to be as follows:-
This invention relates to the operating mechanism of valves for taps and pipes
which are used in connection with fluid substances and has for its objects:
First, increased efficiency in use;
Second, economy in manufacture;
Third, greater sensitiveness of parts;
Fourth, more general utility; and in carrying out my invention in connection
with an ordinary water tap I make the operating mechanism for controlling and
regulating the flow of fluids therein, of a spindle with valve seat, packing and
provisions for guiding it in parallel lines within the valve chambers; also, with
what is the most essential part of this invention, namely, two cam surfaces, and a
non-corrosive spring by means of which the opening and closing of the valve is
principally effected
One of the said cam surfaces is connected with the handle by which the valve
is operated and the other one is connected, loosely, with the aforesaid spindle. Only
one of the said cams is capable of being revolved, the other one travels along
with the valve spindle in parallel lines within a chamber of the said valve or tap.

COMPLETE SPECIFICATION.
Improvements relating to Valves for Taps and Pipes.
I, HENRY RUSSELL of Crown Brass Works Falkirk in the County of Stirling
North Britain Engineer and Brass Founder, 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 :-
This invention relates to the operating mechanism of valves, for taps and pipes
which are used in connection with fluid substances and has for its objects ;
1st, increased efficiency in use;
2nd, economy in manufacture;
3rd, greater sensitiveness, and
4th, more general utility.
In carrying out my invention in connection with an ordinary water tap I make
the operating mechanism for controlling and regulating the flow of fluids therein,
of a spindle with valve seat, packing, and provisions for guiding it in parallel lines
within the valve chambers; also with what is the most essential part of this
invention; namely, two cam surfaces and a non-corrosive spring, by means of
which the opening and closing of the valve is principally effected: a handle of
some kind, being attached, one of the said cam surfaces is connected with some
part of the handle by means of which the valve is operated and the other one is
connected, loosely, with the aforesaid spindle, only one of the said cams is capable
of being revolved within the valve or tap, the other one travels, (along with the
spindle), in parallel lines within a chamber of the said valve or tap.
In order that my invention may be better understood and more easily carried ou

ordinary water tap, in which;
Figure 1 is a sectional elevation of a tap, shewing the application of my improved
valve mechanism, closed;
Figure 2 is a sectional elevation of a tap, shewing the application of my improved
valve mechanism, open;
Figure 3, is a plan of above tap, with parts removed;
Figure 4 is a view in perspective of said tap with parts removed;
Figure 5 is a sectional elevation, similar to that shewn in Fig. 1, but without the
removeable parts of its valve mechanism ;
Figures 6 to 13 are views shewing parts of my valve mechanism detached from
the said tap.
Similar letters of reference and numerals are employed throughout these illus-
trations to indicate corresponding parts.
Referring to the said drawings the inlet for the water is at A, and the outlet
at B, passing through the port E into the chamber C, thence through the port F
into the chamber D, having free escapement therefrom through the port G into the
chamber B as shewn by the arrows in Figure 5. The chamber H, Figures 3, 4
and 5, is furnished, in the complete valve, with parts of the actuating mechanism
of the valve, but is not a water chamber. The metal washer or valve J, Figures 1, 2
and 6, is faced with any suitable soft material, and held forcibly against the face of
the valve seat K by means of the spring L acting upon the cam-faced boss or
head piece M, which, fitted upon the spindle N, Figures 1, 2, 6 and 7, travels
within the chamber H. Upon the washer or valve J, is a pin marked j³, Figure 6,
which rests and travels loosely within a socket, 3, contained in the screwed on cap
or cover P, Figures 1, 2 and 11, and enables the spindle N and its several attach-
ments to move in parallel planes (vertically or otherwise) within its several
chambers C, D and H. The cam-faced head piece M, Figures 1 to 10, contains a
hole m³, for enabling it to be united to the spindle N by means of a cottar, nut and
screw or other simple means and is provided with projecting parts marked R,
Figures 1 to 10 which move within the slots or grooves, Figures 1 to 5; the
engagement of the parts R and being designed to prevent the spindle and its
head piece M being revolved.
The cam-shaped surface of the head piece M, as shewn in Figures 1 to 10
corresponds in form with the cam shaped face, marked U, upon the root of the
handle S, Figures 1 to 13; and in Figure 2 I have shewn how the partial revolution
of the said handle (confined within the screwed-on cap T) brings these two cam
surfaces into operation and depresses the spindle, opening the valve at F and
thereby affording vent to the water confined in chambers A and C. When the
handle S is revolved as shewn in Figure 2, it presses down the spindle and depresses
the valve or washer J from its seat K and at the same time compresses the india
rubber packing V, between the shoulders n³, Figures 6 and 7, and n³ Figure 5, and
prevents any access of water through the bore hole n Figures 4 and 5, into the
chamber H. A washer may be used in place of the enlarged part of the spindle
marked n² for the purpose of compressing the rubber packing V
The valve or washer J is screwed on, or otherwise united, to the lower end of the
spindle N and after the depression of the spindle as before described by the partial
revolution of the handle S, shewn in Figure 2, the continued, or backward,
revolution of the said handle enables the spring L to come into operation for closing
the valve as shewn in Figure 1. The spring L is compressed between its seat
and the cam shaped head piece M, as shewn in Figures 1 and 2 sufficiently to keep
the washer or valve J tightly borne against its seat or flange K, thereby closing
the valve. As the valve J opens against the compressed fluid and closes with its
pressure I find that the greater the pressure of the fluid the more efficiently my
valve operates for cutting off its flow.
The handles, Figure 13 is designed for use in confined positions, and where, a
rigid, lever handle resembling S, Figures 1 and 2 would be an obstruction or have

page_text: insufficient room to work completely round its axis, as the bar & can be pushed back
and forward through the eye t' contained in a stock S³ in the same manner that
the handle of a mechanic's vice is operated.
Although I have, in the foregoing description and drawings limited my delineations
to mechanism associated with a water tap of very ordinary form and character I
wish it to be distinctly understood that my improved valve mechanism is not
limited to articles of this class but is designed for application to a great variety of
pipes (where the valve or valves open against the fluid pressure) for either hot or
cold water and other fluid substances and is adapted for either a high or low
pressure, although most efficient in connection with high pressure fluids.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is;
First. In a valve for controlling fluid substances the combination therewith of
parts of mechanism all substantially as herein described and shewn, for the purposes
specified.
Second. In a valve for controlling fluid substances the combination therewith
of the two cams M and U all substantially as herein described and shewn, or any
mere modification thereof, for the purposes specified.
Third. In a valve for controlling fluid substances the combination therewith of
the handle consisting of a bar permanently contained within an eye t' in the
stock S³ all substantially as herein described and shewn or any mere modification
thereof, for the purposes specified.
