I do hereby declare the nature of this invention to be as follows:-
nozzel or nozzels
My invention can be addapted to any kind of beer engine pump
of taps were any kind of liquids is to be either pumped up or drawn off into any
kind of vessel. My invention can be made of any kind of metal tubing
perpendicularly fixed in front of nozzel of any kind. Inside this tube is a cone
and a taper plug to fit in cone forming a valve. The underside of plug is a piece
of round wire screwed in centre of plug and extending to the bottom of tube. At
the bottom of this round wire is connected a horizontal piece which extends
through a slot in the back of tube. When drawing off liquids horizontal piece is
pushed up the slot perpendicularly by vessel openning the valve and allowing liquids
to pass. The momment it is released by taking away vessel the valve drops preventing
any waste whatever.

Improvements relating to the Nozzles of Beer Engines and like
Apparatus.
I, EDWARD TIRRELL SMITH, of "The Red Lion," Cow Cross Street,
London E.C., Head Barman 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 :-
My invention relates to a device which I purpose attaching to the nozzles of beer
and other engines, or any other kind of tap or cock used for the passage of liquids,
and has for its objects to prevent the usual waste of liquor that more or less obtains
with beer and like engines operated by a pump, arising from the dripping, and the
consequent waste, of a certain portion of liquor, that invariably remains in the
nozzles after the glass or other vessel has been removed therefrom, and further
by reason of the automatic operation of the said device, taps or cocks to which it
is attached need not be provided with the usual key or plug by which the liquor
is turned on and off, as the simple placing of the glass, jug or other vessel beneath
the tap is alone sufficient to start the liquor running, and the removal of the said
vessel therefrom permitting the said device to automatically return to its normal
position, is alone sufficient to stop the passage of the tap or cock, and so shut off
the flow of liquor, thereby rendering my invention particularly adaptable to be
attached to, or employed in the construction of such taps as are used for the beer
or wine casks of private dwellings, thus entirely preventing the possibility of waste
of liquor arising from the imperfect closing of the tap by a servant or other person.
In order that my invention and the manner of its application to beer and other
engine nozzles and taps or cocks generally may be fully and clearly understood I
have hereunto appended a sheet of drawings in which
Figs. 1 and 4 are side elevation and vertical section respectively of an ordinary
beer or other engine nozzle to which my invention has been attached.

page_text: Figs. 2 and 3 are side elevation and vertical section respectively of an ordinary
screw tap or cock, as I prefer to construct them according to my invention, and
which will also serve to illustrate how my said device may be employed in the
construction of, or subsequently attached to ordinary taps and cocks as at present
made and used.
I carry my invention into effect by employing a short length of tubing A, which
may be made of any kind of metal or metal alloy, and of varying dimensions
according to the size of the nozzle or tap to which it is to be attached, the lower
end of which is open while the upper end is preferably covered by a screw cap B,
which serves the double purpose of keeping out dust and dirt, and affording facilities
for cleaning out the tap.
In the case of beer and similar engine nozzles B¹ a certain portion of the delivery
end of this would be cut away, and the tubular portion A be brazed or soldered
thereto, preferably as shewn by Fig. 1, a suitable aperture having previously been
made in A, to form a continuation of the passage in B¹. In the case of taps C
constructed as at Fig. 2, which, by the addition of the dotted outline may also
serve to illustrate any ordinary screw tap as at present made and used, the nosing
or delivery aperture of this would be removed, and the tubular portion A be
connected thereto in like manner, and preferably in the position shewn.
The inner surface of A is provided with a valve seating D, situated in any
suitable position below the junction of A and B¹, or C, as the case may be,
preferably cone shaped for the reception of a like shaped valve E, to which is
attached a depending wire or rod F, to the lower end of which is firmly
connected a horizontal piece G, which extends through a vertical slot H in
the tube A, and may be either straight as at Figs. 2 and 3 or curved or bent
upwardly in any desired manner, as shewn by Figs. 1 and 4, the outer surface of
which would be, preferably, coated or partly coated with a tube or a portion of a
tube J, made of rubber or other soft and resilient material, in order to present a
soft and pliable surface for the reception of a glass or the like as hereinafter
explained. The free end of G would be rendered concave or V shaped vertically
in order to slide freely up and down upon a like shaped guide K, which, in the
case of Figs. 1 and 4, may be fixed upon the outer surface of B¹, but in the case of
taps as at Figs. 2 and 3 this may be in the form of a rod connected to and
depending from C.
The normal condition of the apparatus would be with the valve E resting upon
its seat D as shewn in Fig. 3, by which the passage of the tap or nozzle would be
closed, and the parts E, F, G and J, may be so weighted as to effect this
automatically by the action of gravity alone, but not to depend upon this, I prefer
to provide a suitable spring, the tension of which shall operate in keeping the
bar G in its lowest position, and the valve E upon its seat. I do not confine myself
to any particular form of spring, as I may find it convenient to vary this according
to the form of tap in use, and for such taps or nozzles as shewn in Fig. 1 I may fix
thereon, and depending therefrom, a short length of tube L, enclosing a plunger M,
and a spiral spring N, the tension of the latter operating to force M outwardly
from L, impinging upon G and automatically keeping this in its lowest position,
and the valve E upon its seat D. Or I may find it convenient (especially in the
case of such taps as Fig. 2) to employ a plate spring O as shewn at Figs. 2 and 3,
the tension of which would operate in effecting the same end. The manner of
operation is as follows:
In the case of beer and other similar engine nozzles Fig. 1, when liquor is to be
drawn therefrom, the glass or other vessel, when placed beneath the lower end or
orifice of A, would be caused to raise the bar G, and consequently the valve E
from its seating D, thereby raising the plunger M and compressing the spring N,
as shewn at Fig. 4, when the beer or other liquor may be pumped up in the usual
way, and when the glass or other vessel has been filled, the removal of this will
permit the spring N, to operate in lowering G, and closing the valve E, and so
attain the object of my invention.

page_text: When taps or cocks are constructed as shewn by the full lines in Figs. 2 and 3,
in which, as before stated, no plug or key is needed, the same operation of raising
the bar G by the glass or other vessel, would deflect the spring O, and open the
valve E D, as shewn by the dotted outline of these in Fig. 3, thus opening a
passage for the liquor without the need of a key or plug, the removal of which
said glass or vessel would permit the valve E D to again close the liquor passage
by the agency of the spring O, but when my improved waste preventing device is
connected to taps provided with a key or plug P as shewn by the dotted outline in
Fig. 2, this must of course be turned " on "before the liquor will run, but if
through inadvertence this should not be turned "off" or only partly so, my
improved attachment would nevertheless operate automatically for closing the
passage immediately the glass or other vessel was removed, as previously described.
A book or its equivalent, such as R, may be provided upon C for retaining G in its
highest position when large quantities of liquor are to be drawn off.
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.
