PROVISIONAL SPECIFICATION left by the said George William Garrood at
the Office of the Commissioners of Patents on the 13th March 1878.
GEORGE WILLIAM GARROOD, of Twickenham, in the County of Middlesex.
"IMPROVEMENTS IN COCKS, TAPS, AND VALVES FOR WATER AND OTHER FLUIDS."
This Invention relates to improvements in the arrangement and construction of
cocks, taps, and valves for drawing off and passage of water and other fluids or
liquids, applicable to pressure valves, cistern, closet, and other valves and cocks.
For this purpose, according to my improvements, the main passage of the cock,
tap, or valve is formed with one or more holes or openings forming outlet passages
from a cock, tap, or valve, which when open allow the water or other liquid to flow
from the supply into an annular or other suitable chamber formed around or con-
nected with the main pipe, and from thence to an outlet passage or discharge
pipe.
The collar or cap forming the annular chamber and discharge nozzle can be readily
detached by unscrewing for cleansing or other purposes when required, this arrange-
ment also affording great facility for perforating or forming the outlet holes, openings,
or ports in the tap or valve.
The outlet or series of outlet holes or openings are closed and opened by means
of a sliding plug, the inner end of which carries a cup leather, or a short length of
india-rubber tube, or other suitable material, which covers and closes the outlet
holes or openings when the cock or valve is closed, the pressure of the water or
other liquid acting on the inner surface of the cup leather or tube to press it firmly
to the sides of pipe beyond, over, or upon the outlet passage or passages to cut off
the discharge of the liquid,

page_text: The plug which carries the cup leather may be moved to and fro to open and
close the outlet passage or passages in various ways, according to the purpose to
which the cock, valve, or tap is applied.
For some purposes the plug is moved to and fro by means of a fast threaded
screw, or it may be slid to and fro by hand or lever, a projection on the plug
entering a bayonet-shaped slot in the tube to lock it in position when closed.
The plug of a cock, tap, or valve of this character may be so arranged as to be
self-closing by the pressure of the water or other liquid, or by suitable mechanism.
When applied to a ball-cock or valve the plug is moved to and fro by means of a
short arm on the lever which carries the hollow ball or float.
Cocks, taps, or valves of this improved construction may be connected with the
supply by screws and flanges, or otherwise, in the ordinary manner, as is well
understood; and the simplicity of their arrangement and construction admits of
their being readily taken to pieces for cleaning or otherwise; and as they have
no ground or other valve seating, they are not liable to get out of repair.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said George William Garrood in the Great Seal Patent Office on the 12th
September 1878.
GEORGE WILLIAM GARROOD, of Twickenham, in the County of Middlesex.
"IMPROVEMENTS IN COCKS, TAPS, AND VALVES FOR WATER AND OTHER FLUIDS."
This Invention relates to improvements in the arrangement and construction
of cocks, taps, and valves for drawing off and passage of water and other fluids
or liquids, applicable to pressure valves, cistern, closet, and other valves and
cocks.
And in order that my Invention may be clearly understood and readily carried
into practice, I will proceed to describe the Drawings hereto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view, Figure 2 a longitudinal section, and Figure 3 a transverse
section of an ordinary brass cock or tap arranged and constructed in accordance
with my Invention.
The main passage a of the cock, tap, or valve is formed with one or more holes
or openings a¹, forming outlet passages from a cock, tap, or valve, which when open
allow the water or other liquid to flow from the supply into an annular or other
suitable chamber b formed around or connected with the main pipe, and from thence
to an outlet passage or discharge pipe c.
The collar or cap 6¹ forming the annular chamber b and discharge nozzle c can be
readily detached by unscrewing for cleansing or other purposes when required, this
arrangement also affording great facility for perforating or forming the outlet holes,
openings, or ports a' in the tap or valve,

page_text: The outlet or series of outlet boles or openings a³ are closed and opened by means
of a sliding plug d, the inner end of which carries a cup leather, or a short length of
india-rubber tube, or other suitable material e, which closes the outlet passage, holes,
or openings a when the cock or valve is closed, the pressure of the water, or other
liquid acting on the inner surface of the cup leather or tube e to press it firmly over
or upon the outlet passage or passages to cut off the discharge of the liquid.
The plug which carries the cup leather may be moved to and fro to open and
close the outlet passage or passages in various ways, according to the purpose to
which the cock, tap, or valve is applied.
For some purposes the plug is moved to and fro by means of a fast threaded
screw a*, as shown in Figure 2; a projection d' on the plug d enters a slot in the
barrel a of the tap to prevent the plug d from revolving; or the plug d may be
slid to and fro by hand or by a lever, a projection on the plug entering a bayonet-
shaped slot in the tube to lock it in position when closed.
Figure 4 shows a longitudinal section of another form of cock or tap, in which
the plug d is moved to and fro by means of a revolving cap d, having an internal
screw thread into which a projection d on the plug d enters to move it to and fro
when the cap d is turned to open and close the tap. The projection d¹ slides to and
fro in a slot in the barrel a of the tap to prevent the plug d from revolving. The
cap d² is retained in position by a hook or finger a², which embraces a collar formed
on the cap d'
When applied to a ball-cock or valve, as shown by Figure 5, the plug d is moved
to and fro by means of a short arm f¹ on the lever f, which carries the hollow ball
or float; or the plug of a cock, tap, or valve of this character may be so arranged
as to be self-closing by the pressure of the water or other liquid, or by suitable
mechanism adapted for the purpose, as will be readily understood by a competent
mechanic.
Cocks, taps, or valves of this improved construction may be connected with the
supply by screws and flanges, or otherwise, in the ordinary manner, as is well under-
stood; and the simplicity of their arrangement and construction admits of their
being readily taken to pieces for cleaning or otherwise; and as they have no ground
or other valve seating, they are not liable to get out of repair.
Having thus described the nature of my Invention, and the manner of performing
or carrying the same into practice, I would remark that I do not confine myself to
the exact details herein-before described, neither do I claim any of the parts sepa-
rately which are well known and in common use, but what I claim is, the improved
arrangement and construction of cocks, taps, and valves, in which a sliding plug d
combined with a cup leather or other flexible or elastic valve e acts to open and
close an outlet passage or passages, substantially in the manner herein-before
described, and represented in the Drawings hereto annexed.
In witness whereof, I, the said George William Garrood, have hereunto set my
hand and seal, this Ninth day of September, in the year of our Lord One
thousand eight hundred and seventy-eight.
