PROVISIONAL SPECIFICATION.
Improved Attachment for Beer Engine and other like Nozzles.
EDWARD TERRIL SMITH Head Barman Red Lion 44 Cow Cross Street.
London. I do hereby declare the nature of this invention to be as follows:-
A piece of round indiarubber tube. At one end of this tube is a thinner piece
of indiarubber tube joined on to it. At the bottom of this piece of indiarubber it
becomes flat almost to a point; at this point there is a slot in it to let the liquids
pass through this hole. Directly the liquid stops running this hole closes and
stops all liquids from running after you have turned off your taps or stopped
pumping up. By pinching the broad side of this flat piece of indiarubber it opens
the hole and shows you what it has saved. This invention can be made to any
size to fit beer engine taps or cocks where there is liquid to be drawn off or pumped
up likewise preventing glasses from getting broken against the nozzles.

COMPLETE SPECIFICATION.
Improved Attachment for Beer Engine and other like Nozzles.
I, EDWARD TERRIL SMITH of The Red Lion, 44 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 the construction and use of india rubber teats or nipples
which I purpose fixing upon the nozzles of taps or cocks, through which liquids
have to be drawn off or pumped up, and which in its application is particularly
adapted for use upon the taps or cocks of beer engines as employed by publicans
generally, the object of my invention heing to prevent the usual waste of beer or
other liquid occasioned by this dripping from the tap after the pump piston has
been returned to its normal position, and in the case of beer engines, to prevent
breakage of glasses by providing a soft or resilient surface against which these may
collide when placed for filling beneath the tap.
In order that my. invention and the manner of its application may be fully and
clearly understood reference may be made to the accompanying drawings, in
which,
Figs. 1 and 2 are front and side elevations respectively of the said rubber teat
or nipple, while Fig. 3 is a top and bottom view of same.
Figs. 4 and 5 are views illustrating the manner of operation of Figs. 1 and 2
when fixed upon the taps of publicans beer engines.
Fig. 6 is a perspective view of a fancy cap I may employ as hereinafter
explained.
In carrying my invention into effect I employ short lengths of rubber tubing A
of various diameters according to the size of the taps upon which they are to be
used, and during the manufacture of these, which may be previous to vulcanization,
I either attach thereto by means of solution or other cement, a nosing B, made
from thinner rubber, and flattened as at Fig. 3, previous to joining to A at or about
the position shewn by the dotted line in Fig. 2, or I may so mould the portion A
that its lower end B is flat and the aperture at that end always closed (as at Fig. 3)
"

page_text: while its upper end is always open (as at Fig. 3) when in its normal position. These
are simply details of manufacture and in nowise affect the principle or effectiveness
of the operation of the said teats or nipples, which is as follows.
The said teat or nipple would be sprung upon the nozzle of the tap C of the beer
or other engine D, the elasticity of which would in most cases be sufficient to retain
it in that position, if otherwise, this may be fastened thereon by a binding of
flexible wire, and to cover such binding and add to the general appearance of the
said rubber attachment, I may employ fancy shaped caps or covers E, such as at
Fig. 4, in which a longitudinal split a may be provided that this may be sprung
over A, as shewn by the dotted outline of same in Fig. 4.
When first placed upon the tap C, the said teat or nipple would appear as at
Fig. 5, but when the pump lever of the engine D is drawn down in the direction
of the arrow Fig. 4, and beer or the like forced through the teat or Dipple, the
lower end B of this would open and permit this to pass freely as shewn in Fig. 4,
but upon the commencement of the return or upstroke of the lever Fin the
direction of the arrow Fig. 5, and the consequent cessation of the flow of liquor, the
mouth B would close automatically, and by reason of the partial vacuum in
the tap Coccasioned by the finish of the upstroke of the lever F, and the
atmospheric pressure upon the outer surface of B, this would remain so closed, and
hold within itself such portion of liquor as would be left in C after the glass or
other vessel had been removed therefrom, and which but for the presence of my
invention, would drip and run to waste.
My invention may be also used with effect upon taps and cocks through which
spirits and other liquors are led by gravity, and although the automatic closure
of B would not be quite so persistent as when enclosing a vacuum, it would
nevertheless be effective in preventing waste of such quantity as usually drips from
such taps immediately after use.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1st. In an improved device for retaining, and preventing the waste of, drippings
from taps, cocks, and the nozzles of beer and like engines, the application and
affixation thereto of a rubber teat or nipple such as A B, Figs. 1 and 2, substantially
as herein described and shewn.
2nd. The use and application of the herein described rubber teat or nipple A B,
constructed in one piece as at Fig. 1 or in two parts connected by solution or other
suitable cement as at Fig. 2, substantially as and for the purposes herein set forth
and shewn by the accompanying drawings.
