I, HARRY JAMES YATES, trading as Arden Hill and Company, of Wharf Road,
Aston, near the City of Birmingham, Gas Engineer, do hereby declare the nature
of this invention to be as follows:-
This invention relates to taps for cutting off or controlling or regulating the
supply of gas to two or more burners, pipes or passages, said gas being fed from
a single inlet or supply. The object of the invention is to completely turn on
gas for two or more burners, and to regulate the supply of gas to two or more
burners, to supply gas to only one or more burners, the supply to the other
burner or burners being then cut off, and to fully cut off gas from the whole of
the said burners, and to admit of a bye-pass gas supply to the burners when the
cock plug is in its fully cutting-off position, the whole of the means for effecting
the aforesaid controlling and cutting off operations being combined in one tap.
In carrying out my invention with a single inlet and double outlet tap, I take
a conically socketted body part having a single inlet directed from one side,
and which may come opposite to one of the outlets directed from the other side of
the body, whilst above this outlet is a second one, leading, alike unto the first,
to a separate burner, branch, pipe or equivalent.
Working within the socket, which may be open at top and bottom, is a conical
plug, having a turn at its upper end and a screwed stalk at its lower end for
receiving a screw washer and nut which abuts against the walls of the socket
for preventing the plug, which has a limited turning motion, from rising.
Directed in a line with the axis of the inlet and one of the outlet passes, and
also across the plug, is a thoroughfare gas way leading into an axial hole or
hollow passage through the plug, and terminating in a passage or gas way
coming upon the off-side of the said plug and coincident with the second named
outlet of the tap.
A bye-pass channel extends from the outlet of the second gas-way to a distance
(equal to about a quarter turn) around the back of the plug whilst a further
by-pass channel extends from the inlet to the outlet of the first-named gas-way.
Thus the socket or body has two outlets on the one side and a single inlet upon
the opposite side. When the gas is fully cut off, the gas ways in the plug are
at right angles to the gas ways of the socket but the channelled bye-pass of
the all-through gas way comes opposite the inlet passage and the other bye-pass
comes opposite the second outlet passage, so that gas passes round the first channel
and into the inside hollow of the plug, and then ascends and passes through
the second-named outlet to the bye-pass jet.
On turning the plug through the quarter of a circle, then the second-named
gas way is coincident with the second outlet, whilst the other gas way is coinci
dent with the inlet and the first-named outlet, but when the plug is turned back
through half a revolution, the thoroughfare gas way in the plug is in line with
the inlet and first outlet but the second named outlet is closed."

page_text: It is understood that communication from the one gas-way to the other is
obtained through the hollow axial passago in the plug, and that by having a
single bye-pass to only the one burner, the other burner is lighted, when gas is
turned on, through them being in close proximity to one another, and also that
the bye-passes and the gas ways to the burners inay be cut off by turning the
plug so as to bring the whole of the holes opposite to solid parts of the body
of the plug.
Where the cock is to control the supply of gas to more than three burners
or branches, then the plug is provided with a corresponding number of gas ways
and bye-pass passages each in communication with one another through the
central or axial passage up the plug.

I, HARRY JAMES YATES, trading as Arden Hill and Company, of Wharf Road,
Aston, near the City of Birmingham, Gas Engineer, do hereby declare the naturo
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:—
This invention relates to taps for cutting off and controlling or regulating
the supply of gas to two or more burners, pipes or passages, said gas being fed
from a single inlet or supply. The object of the invention is to combine in
a single tap, means for completely turning on gas for two or more burners, and
to regulate the supply of gas to the same; to supply gas to only one or more
burners, the supply to the other burner or burners being meanwhile cut off;
and to admit only a bye-pass supply of gas to one burner, the other burner mean-
time having a full supply.
Figure 1 of the accompanying drawings represents in vertical section, a gas tap
constructed according to one form of my invention provided with a single gas
inlet passage and designed to admit, cut off and regulate the supply of gus
to both or either of a pair of burners, pipes or the like. In this view, the plug
by which the several cutting off and controlling operations are performed is
represented in a position in which gas is entirely cut off from both burners.
Figure 2 is an elevation of the tap looking at the same from the inlet end,
and with the upper walls of the body part broken away to show a portion of
the plug in elevation.
Figure 3 is a view, partly in section, of the tap with the parts in the same
position as in Figure 1, but with the plug shown in elevation.
Figure 4 is a like view, partly in section and partly in elevation, as Figure 3,
but with the tap turned round in order to show the other side of the plug and the
gas ways or channels provided within its outer walls.
Figure 5 is a horizontal section of the tap upon the dotted liner, Figure 3
showing the passages provided in the walls of the plug (which is hollow) for
admitting gas into the top burner.
Figure 6 is another horizontal section of Figure 3, but upon the dotted lines r¹,
showing the arrangement of the supply passages and bye-passes by which gas

page_text: communication is effected from the hollow of the plug to the second or lower
burner.
Figuro 7 is a vertical section of the body of the tap separately, showing the
bye-pass channel within its inside walls.
Figure 8 represents another vertical section of the tap (but with a part of
the plug in elevation) but showing the plug turned (by a quarter turn) into a
position which will admit a full supply or gas to the bottom burner only.
Figure 9 is a horizontal section of the tap upon the dotted line, Figure 8,
showing how a direct gas way is established between the inlet passage and the
bottom burner when the plug is in the position represented in the said Figure 8.
Figure 10 is a further vertical section of the tap, with a part of the plug in
clevation, showing the said plug in a further position in which a full supply of
gas is admitted to the top burner, but only a bye-pass supply to the lower burner.
Figure 11 is a horizontal section of Figure 10 upon the dotted lines, showing
direct communication opened between the hollow of the plug and the top burner
or outlet.
Figure 12 is another horizontal section of Figure 10, but upon the dotted
line, showing how (when the plug is in this position) there is open communica-
tion between the gas supply and the hollow interior of the plug whilst gas can
only flow from the said plug to the lower burner through the bye-passes.
Figure 13 is a still further horizontal section of the plug and upper burner
passage, showing the position of the gus ways in the said plug when it is turned
for admitting a full and equalized supply of gas to both burners at the same
time.
Figure 14 is a section of the said tap taken through the lower part of the plug
and lower burner passage, with the plug in the same position as represented in
Figure 13.
The same letters of reference indicate corresponding parts in the several
figures of the drawings.
The form of single inlet and double outlet tap represented in the said figures
thus has conically socketted body part a, with a single inlet b, directed from
one side and preferably coming opposite to or in a line with the lower outlet c,
directed from the other side of the said body, whilst above this lower outlet is
a second and upper one d, leading alike unto the first, to a separate burner, brauch,
pipe or equivalent.
Working within the socket, which in this arrangement, is open at top and
bottom, is the conical plug e, having a handle or turn el, at its upper end and
a screwed stalk, at its lower end for receiving a washer e, and nut, which
abuts against the lower end of the socket for preventing the plug (whose turning
motion is limited by a stud e, upon it coniing against shoulders or stops a',
upon the body) from rising. Directed in the same horizontal plane as the axes
of the inlet b, and lower outlet c, and also across the plug, is a thoroughfare
hole or gas way, leading into the hollow interior g, of the plug, and coming
coincident with a second hole, passage or gas way f, made through the opposite
or off side wall of the said plug and adapted-in certain positions of the plug
(see particularly Figures 8 and 9) to come over the end of the outlet passager,
and thus afford a direct gas way from the inlet b, through the hole f, and hollow g,
of the plug and opposite hole f, to the burner passage c.
A bye-pass channel or groove is formed for a distance (equal to about a half
turn), around the inside walls of the body, and thus extends from the outlet
passage, of the tap nearly to the inlet passage whilst intermediate between the
Anid holes f, f', is a third hole f³, made through the walls of, and leading to the
hollow of the plug and serving--when the plug is in the position shown in
Figures 10, 11 and 12- to come in line with the inlet passage and allow
to pass to the said interior for both admitting gas through the bye-passes to
the lower outlet c, and also to the upper outlet d, to which gas passes from the
inside of the said plug through a hole h, made in its walls at a point in the
gras

page_text: same horizontal plane as the axis of the said outlet d, whilst in order to provide
for the full supply of gas to the top outlet being maintained when the plug is
in position shown in Figures 13 and 14 in which the supply is full ou to both
outlets, a second hole 4, is provided in the same plane, which is opened to the
outlet d, on the hole, being turned opposite to the solid walls of the body as
in Figure 13. When the gas is fully cut off from both outlets the gas ways ff,
and h, in the plug are in positions at right angles to the outlets c and d (see
Figures 5 and 6) and the inlet passage b, is completely closed against the admis-
sion of any gas whatever by the solid or unpierced part a, of the walls of the
plug coming opposite to it, as best represented in Figures 1 and 6
To provide against the supply of gas being momentarily cut off from either
of the outlets during the time that the plug is being turned from one position
to another, the outer walls of the said plug are channelled or provided with
external passages i, j, respectively forming an outside communication or gas
way between the set of lower holes f, f', f³, and the upper holes or passages h, h',
and which said passages are adapted to come over the outlet and admit of the
supply of gas flowing uninterruptedly to them during the turning of the plug
in bringing a different hole or holes coincident with either or both of the said
outlets.
Further, it will be observed that the inlet hole f, through which gas enters
when the parts are as in Figures 13 and 14, with full supply to both burners,
is larger than the other two holes f. f³, for as will be understood that if the
opposite holes f, f', were made of the same size, a direct passage would be
provided through which gas would pass or be drawn to the lower burners in
excess of the amount fed to the upper one, therefore in order to balance the
feed or equalize the distribution, the two holes f, f³, are made smaller than
the inlet hole fl, and yet are in communication with one another through the
passage i, in the outside walls of the plug, so that part of the gas enters the
outlet c, direct through f, whilst a further supply enters by way of the hole
and passage i
Assuming the tap to be in the position shewn in Figures 1 to 6, in which gas
is cut off completely from both the outlets, and that it is desired to admit gas to
the lower outlet, the plug is given a quarter turn from right to left (in the
direction of the arrow in Figure 6) which brings the holes f, f, into the positions
relative to the inlet b, and outlet c, shown in Figures 8 and 9 and provides a
thoroughfare gas-way between them, gas being meantime fully cut off from
the upper outlet. If a full supply to the top outlet and a bye-pass supply to
the lower outlet only is required, the plug is given a further quarter turn in
the same direction and brought into the position represented in Figures 10, 11
and 12, in which gas is admitted to the hollow of the plug through the hole f³,
and passes to the top outlet through the hole h, and to the lower outlet by flowing
through the holes f, f', to the bye-pass channels in the walls of the plug leading
to the outlet c. The full supply to both outlets is opened by giving the plug
a still further quarter turn, in the same direction as before, which again estub-
lishes the thoroughfare gas-way to the outlet c, by the holes f, f, whilst the
gas for the upper outlet d, passes out of the hollow of the plug through the
hole h¹.
Instead of limiting the movement of the plug by a stud upon it and stop
shoulders on the body, these may be dispensed with so that the plug may then
be turned through the full rotation, so that the full gas supply to both outlets
may be opened at once by turning the plug (when as in Figure 1) from left to
right through a quarter of a circle.
Where the cock is to control the supply of gas to more than two burners or
branches, then the plug is provided with a corresponding number of gas ways
and the required bye-pass passages, each in communication with one another
through the central or axial passage up the plug.
Instead of the bye-pass being arranged to supply gas to the lower outlet, it

page_text: may be arranged in connection with the upper outlet, whilst instead of the inlet
passage being disposed in a line with one of the outlets, it may be arranged in
any other convenient position, in which case a suitable lead passage would be
formed in the walls of the tap body for conveying gas to one or other of the
series of holes in the plug, which are all in intercommunication with one
another through the hollow or axial bore of the plug.
In addition to providing a convenient means of controlling the gas supply to
two or more burners or pipes by a single plug, all liability of the burner to
"light-back" is, by my invention, fully obviated.
Having now particularly described and ascertained the nature of my snid
invention, and in what manner the same is to be performed, I declare that what
I claim is
First: A gas tap, having a single inlet and double or multiple outlets, and
a plug or equivalent provided with series of lateral gas-way passages, intercom-
municating with one another and respectively located in the same planes as,
and adapted to be brought into communication with, the outlets of the tap, and
with suitable bye-passes.
Secondly-A gas tap having a single inlet and double or multiple outlets, and
a bollow plug, the walls of which are pierced with series of holes or gas-way
passages in intercommunication with one another through the interior of the
said plug, and respectively disposed in the same planes as the outlets of the
tap, with suitable bye-passages arranged between either of the series of holes
in the plug and its corresponding outlet, substantially as described and set forth.
Thirdly-In gas taps having a single inlet and double or multiple outlets
as referred to in the preceding claims, the arrangement of the bye-pass channels
in the body of the tap, substantially as herein.described and set forth.
