running up from the smaller end of plug, or running in from a nipple on the side:
of the barrel opposite the aforesaid pipe or nozzle, in which case the hole runs
right thro' the plug & into the other side of the barrel. The narrow end of the
plug, or the nipple as the case may be, is connected immediately, or by means
of a tube, with the vessel containing the second fluid. The rush of the fluid under
pressure round & past the aforesaid pipe or nozzle creates a partial vacuum in same

piece or rose. When the plug is reversed by being turned half round, the stop
cock reverts to one of ordinary action. The plug is secured by the usual washer
& screw or nut.

with another, the ordinary stop cock is altered as follows. The fluid under
pressure on entering the barrel of the cock is divided into two streams;
Jarger of the two passes on thro' the ordinary holes in the barrel & plug & out
thro' the jet piece or rose; the second or smaller stream is conducted by a
second hole in the barrel & plug into a pipe running up to meet it thro' the narrow
end of the plug, which pipe conducts it to the bottom of the vessel containing the
soluble substance, it there mingles with the substance & filling the vessel flows up
thro' an annular space in the plug round the said pipe, until it reaches a hole in
the side of the plug opposite, but lower down than, that by which it entered; this.
hole communicates with the jet-piece or rose by an inclined hole in the barrel, &.
the fluid passing along it meets the larger stream, mingles with it, & issues forth..
The vessel containing the soluble substance is either screwed on immediately to
either the barrel or end of plug, or communicates with one of them by means of
tubes.placed side by side or one inside the other. As before, when the plug is :
reversed, the cock reverts to one of ordinary action.
In both the aforesaid appliances the holes in the barrels & plugs being of much
less diameter than the main holes as usually found in plug cocks, a slight circular
movement of the plugs closes the former, without materially affecting the flow of.
fluid thro' the latter, & so a power of regulating & cutting off the flow of the
second fluid in each case is obtained...
In order to indicate & when so desired, to fix the quantity of the second fluid

page_text: passing in a given time, a plate with arms half embracing the upper part of the
plug is attached by a screw & curved slot over the top of the barrel. This plate
has an index point passing over a divided quadrant face on barrel. On upper face
of plate is a stop, which meets with the pin-stop usual in plugs of cocks & when
said plate is secured by said screw in a certain position, the plug can only revolve
within certain limits, so indicating & fixing temporarily the quantity of the second
fluid passing thro'. This plate & screw are applicable to both the aforementioned
appliances.
Two or more of either of the aforesaid appliances may be combined in a series,
when certain modifications may be introduced without departing from the spirit of
the invention.
For instance, if it is desired to mix the combined fluids issuing from the
apparatus last described with other-fluid or fluids-then the jet piece or rose of
said apparatus is replaced by a tube, which conducts the combined-fluids round a
small pipe or nozzle similar to that in apparatus first described herein, which pipe
or nozzle communicates with the external vessel containing the other fluid & is in
this case regulated by a cock placed at some point in said communicating passage.
Again, if fluid under high pressure has to be dealt with, instead of the plug
form of stop cock, a high pressure screw tap with certain analogous modifications
is used, principally consisting of additional pins in the disc that closes the passages
of entrance & exit, such pins moving in & out of suitable holes in the passages
of the secondary fluids & regulating their flow.
The vessels containing the secondary fluids or substances may be conveniently
cylindrical in shape, & having sides projecting above tops to form a receptacle for
the hose or pipe, when not in use, with proper handles or fixed on wheels, &
proper modes of refilling, attachment of hose, or other pipe, & admission of air.

1, WILLIAM HANLON M.A. of the Rectory, Innishannon, Co. Cork, Ireland
Clerk in Holy Orders 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 statenient :-
The object of this invention is to provide stop cocks which while capable of all
the uses of ordinary stop cocks.will, when so adjusted, draw in, mix & distribute
two or more fluids or will cause a fluid to mix with a soluble substance & will cause
the resultant solution to combine with other fluid or fluids.
Where it is desired to mix two fluids I provide a plug stop cock of which Fig. I
is a vertical longitudinal section having in addition to the usual passages the
anterior cylindrical chamber. A A & the posterior cylindrical chamber B & the
smaller secondary horizontal passage C through the plug & the corresponding
passages D & E in the cock body & the tube F inserted in the said passage E.
Into the chamber A. A is fitted the front piece C & into the chamber B is
detachably fixed the pipe H.
The action is as follows:-Fluid under pressure is admitted to the pipe I & the
plug being in the position shown, the fluid passes into the chamber A A, round the
tube F & out through the front piece G. The rush of fluid round & past the tube F
causes a partial vacuum in it & in the passage E. C. D, chamber B & pipe H, so

page_text: drawing up any fluid into which the lower end of pipe H may be immersed & mingling:
it with the fluid under pressure as it issues from the front piece G. The diameter
of the passages D. C. E. being much less than that of the upper passage J in the
plug a slight turn of the plug will lessen or cut off the flow of fluid through the
passages D. C. E., without materially diminishing the flow of the fluid under-
pressure.
Where it is desired to dissolve soluble substances & mingle the resultant solution
with another fluid I provide a plug stop cock, of which Fig. II is a vertical.

& the passage B in the cock body & in the plug the respectively corresponding.
passages C. & D. & the vertical passage of two diametres E into the upper &
lesser end of which is detachably fitted the pipe F open at both ends the lower end
being attached in any suitable manner to the vessel G which vessel-is detachably
fixed to the lower limb of the cock body.
The action is as follows, fluid under pressure, being admitted to the pipe I, part.
passes through the usual passages & out at the front piece H portion enters the
depressed slot A flows through the passage C in plug & down the pipe F to the
bottom of the vessels G, it dissolves some of the soluble substance therein &
the resultant solution rises through the annular passage E round pipe F passes D & B
& mingles with fluid under pressure issuing at H. Its flow is regulated or cut off
as before described.
Figure 111 represents in vertical longitudinal section a combination of the tw
forms already described. According to the position of the plug it will either mingle-
a fluid with the fluid under pressure or it will cause part of the fluid under pressure
to mingle with the soluble contents of the detachable vessel G & cause the resultant.
solution to issue through the pipe A & mingle with the other portion of the fluid
under pressure.
The action is as follows. When the plug is in the position shown a part of the
fluid under pressure passes through the passage C & pipe F into the vessel G
dissolves some of the substance therein & rises through the annular passage E &
the pipe A & mingles with the issuing fluid. When the plug is turned half round
the passages & B are closed & the passage D registers with the pipe A & the
lower end of the plug being connected by means of a suitable pipe with a vessel
the action described in connection with the first described apparatus is set up.
Where this form of cock is employed it may be necessary to use a vessel with.
two compartments of which Figure IV is a vertical longitudinal section F being
the pipe passing into plug & A a secondary chamber communicating with the
principal one by means of a pipe B. The fluid under pressure descends into either
of these chambers, displaces the air & so equalizes the pressure in both compartments.
facilitates the action of the stop cock.
In all three forms of this apparatus hereinbefore described the larger & smaller
sets of passages in cock body & plug may change their relative positions the smaller
sets being above instead of below the larger as shown; and the front pieces may
be fitted with a jet or rose or spreader either immediately or by means of a length.
of pipe.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the saine is to be performed I declare that what I
claim is-
1st. In a mixing or ejector stop cock for mingling two fluids, the anterior &.
posterior cylindrical chambers the secondary passage in the plug & the two passages
in the cock body registering therewith; the pipe fixed in the anterior of these:
passages & the detachable pipe fitting the posterior chamber, substantially as & for
the purposes described.
2nd. In a mixing or ejector stop cock for dissolving a soluble substance &
mingling the resultant fluid with another fluid, the secondary horizontal passage in.
the plug & the vertical passage of two diametres in the same with the passage-

page_text: opening from the larger of these latter vertical passages into the secondary passages
in the cock body, the pipe fitting the smaller of these vertical passages & the
detachable vessel with the last named pipe attached to the bottom thereof,
substantially as & for the purposes described.
3rd. In a mixing or ejector stop cock combining the two actions aforesaid, all the
parts & passages aforesaid with the additional horizontal passage in the plug
running from the larger vertical passage in the same, &. the vessel of two
compartments, one communicating with the plug & with the other compartment
by means of a tube substantially as & for the purposes described.
Dated this 29th day of March 1897.
