Improvements in Combined Right and Left Handed Stop and
Waste Cocks.
I, HERBERT JOHN HADDAS, of the firm of Herbert Haddan & Co., of 18,
Buckingham Street, Strand, London, Patent Agent, do hereby declare the nature
of this invention a communication to me from abroad by Frank A. Radcliffe,
of Cleveland, in the County of Cuyahoga, and State of Ohio, in the United
States of America, Manufacturer and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
The invention relates to improvements in combined right and left handed
stop and waste cocks; and it consists in the peculiarities of construction and
combinations of parts hereinafter described and pointed out in the claim.
In the accompanying drawings, Fig. I is a side elevation, mostly in central
vertical section, of a stop and waste cock embodying the invention. The parts in
this figure are shown in position for use as a left handed cock. Figs. II and
1II are sections on line II-II and line III-III, respectively, Fig. I. In the
position of parts shown in Figs. I, II and III the lateral port through the
tapering plug registers with and establishes continuity in the passage way
through the valve casing. Figs. IV and V are sections corresponding with
Figs. II and III, except that in the position of parts shown in Figs. IV and V the
waste hole in the plug registers with the discharging end of the passage way
through the valve casing, and communication between the two ends of said
passage way is interrupted, and the port through the valve communicates with
the waste hole in the valve casing, and the position of the handle in the position
of parts shown in said Figs. IV and V is indicated in dotted lines in Fig. IV.
Figs. VI, VII, VIII, IX and X correspond with Figs. I, II, III, IV and V
respectively, except that the parts in the last five figures are shown in position
equired to form a right handed cock.
Referring to the drawings. A represents the casing of the improved stop and
waste cock, and B designates the tapering plug or valve that is suitably seated
in a corresponding chamber in the valve casing, and has a lateral port adapted
to establish continuity in the passage way A' through the valve casing. One of
the side walls of plug B is provided with a waste hole that is adapted to com-
municate with the one or the other end of the passage way through the valve
casing by turning the plug or valve upon its axis in the direction and to the
extent required, and the arrangement of parts is such that when the plug or valve
is actuated to bring said waste hole in line with the passage way through the
valve casing port of the plug or valve shall be in open relation with waste hole a
extending laterally through one side of the valve casing.
It is not considered necessary to illustrate the stop and waste cock attached to
the water supply pipe or to the pipe to be supplied with water. Suffice it to state
that one end of the valve casing is adapted to connect with the supply pipe, and
the other end with the pipe to be supplied.
A handle C, hereinafter referred to, is provided for turning the plug.
It is here remarked that the device is considered right or left handed according

page_text: as the right or left hand of the passage way through the valve casing is the
discharging end of said passage way.
The tapering plug of the improved stop and waste cock at its larger end
terminates in a circular extension B', that extends outside of the valve casing,
as shown in Figs. I and VI, and is provided centrally with a pocket B, that
extends from the outer extremity of the aforesaid circular member of the plug
inwardly a suitable distance and is angular in cross section, as shown in Figs. III,
V VIII and X. The valve casing at the inner end of the circular portion of the
plug (that portion of the plug that extends outside of the valve casing) is provided
with an annular shoulder A2. A sleeve D embraces member B of the plug and
at its outer end is provided with an internal annular flange or seat, D', engaging
the outer end of and resting upon said circular member 13 of the plug, as shown
in Figs. I and VI. Sleeve D comprises a single casting that nicely embraces
member B of the plug. The sleeve's lower end and thicker portion, at D2, fits
against shoulder A2 of the valve casing, and extends downwardly to form an
annular member 13 that snugly embraces that portion of the valve casing that
is provided with shoulder A2 and thereby excludes ingress of dust and dirt into
the sleeve from below. Portion of the sleeve is provided, in its under side,
with a groove or recess Do that extends about one third of the distance circum-
ferentially of the sleeve and is arranged concentrically of the plug's axis. The
end walls D and D³ of said recess D form shoulders or movable stops that are
adapted to engage opposite sides, respectively, of a lug a² formed upon shoulder A*
of the valve casing, and hence the plug, when the sleeve is secured thereto and
placed in position with one of its shoulders D D engaging one side of lug or
stationary stop a can only be turned in one direction and a distance equal to
the interval between the opposite side of said lug and the other of said shoulders.
Hence one of shoulders D 15, in conjunction with one side of lug a² on the valve
casing, forms a stop to limit the movement of sleeve D and connected plug or
valve and operating handle in the one direction, and the other of said shoulders,
in conjunction with the opposite side of said lug on the valve casing, consitutes a
stop to limit the movement of said parts in the opposite direction.
It will be observed that the operating handle at its inner end is provided with
an annular flange or shoulder C, that engages the outer side of internal flange
or seat D', of sleeve D and thereby excludes the ingress of dust or dirt into
sleeve and pocket B2 from the outer end of the sleeve. The handle at the
inner side of fiange ("is ir vided with an angular projection (3, that corresponds
with and engage pocket 132 in the plug and establishes operative connection
between the handle and plug.
Sleeve D is operatively secured to the plug by means of a screw E that extends
through a holed in said sleeve and through a correspondingly threaded hole B³
in the handle engaged member B of the plug, and at its inner end preferably
engages a depression ("formed in the angular projection of the operating handle,
and it is here remarked that member B₁ of the plug must be provided with two
screw receiving holes d, arranged at right angles to each other and radially to
the axis of the plug, one of which holes is for the purpose of receiving the securing
screw when the parts are in position for use as a right handed cock, and the other
hole being for the purpose of receiving the screw when the parts are assembled
for use as a left handed cock.
In the use of the device as a left handed stop and waste cock the parts are
assembled as shown in Figs. I and II. In Pii the port through the plug or
valve is shown in line with the passage way through the valve casing and the
operating handle extends in the directon of that end of the valve casing that is
designed to be attached to the pipe to be supplied. Hence the handle is turned to
the left in cutting off the supply to said pipe and in order to drain said pipe
(see Fig. IV, wherein the port through the plug or valve is shown communicating
with ae waste hole in the valve casing, and wherein the waste hole in the plug
or valve is shown in communication with that end of the passage way through the

page_text: valve casing that is adapted to communicate with the pipe to be supplied). The
arrangements of parts in Figs. I, II and III is such that when the plug or valve is
in position with its port establishing continuity in the passage way through the
valve casing, shoulder D of sleeve D shall engage the right hand side of lug a²
on the valve casing and waste hole in plug or valve B shall be at the rear and
consequently closed, and when the parts are turned to the left in order to interrupt
continuity in the passage way through the valve casing shoulder D' of sleeve D)
shall come into engagement with the left hand side of the lug on the valve casing,
as shown in Fig. V and the waste hole in the plug or valve is brought into line
with that end of the passage way through the valve casing that is adapted to
connect with the pipe to be supplied, as shown in Fig. IV.
In order to use the device as a right handed stop and waste cock, the arrangement
herein before described is reversed so far as sleeve D and the operating handle are
concerned namely, the operating handle, as shown in Fig. VI, extends to the
right or in the direction of that end of the valve casing that is adapted to
connect with the pipe to be supplied. In the case of the right handed
stop and waste cock, therefore, shoulder D of sleeve D, when the plug or valve is
in position establishing continuity in the passage way through the valve casing,
engages the left hand side of the lug on the valve casing, as shown in Fig. VIII
and in order to interrupt continuity in said passage way and thereby cut off the
supply to the pipe to be supplied and to drain said pipe the operating handle and
consequently sleeve D and the plug or valve are turned to the right until
shoulder 15 of said sleeve engages the right hand side of the lug on the valve
casing as shown in Figure X, thereby bringing the waste hole in the plug or
valve into open relation with that end of the passage way through the valve casing
that will connect with the pipe to be supplied and bringing the port through the
plug or valve into communication with the waste hole in the forward side of the
valve casing, as shown in Fig. IX.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
The combination of the casing A provided with the passage way A, the waste
hole a and the annular shoulder A having the lug 2; the tapering plug B
provided with the port the waste hole and the circular member B₁ with the
latters angular pocket B2 and two screw threaded holes B³ sleeve D having
the internal annular dust guard forming flange D', the lateral hole d, the
annular dust guard D³, and the groove or recess D with the latter's shoulder
forming end walls D and D' the screw E and the handle with its angular lug
or projection C, all arranged and operating substantially as shown, for the
purpose specified.
