page_text: I THOMAS FITZROY KELLY of 138 Victoria Park Road, South Hackney in the
County of Middlesex, Brewers Engineer do hereby declare the nature of the said
invention for "IMPROVEMENTS IN BEER ENGINES FOR AERATING AND RETAILING
LAGER AND OTHER BEERS to be as follows
"
My invention has for its object to adapt the ordinary beer engine form of
apparatus for retailing Lager Beer and similar beverages, and thereby to reduce
the cost of machinery, economise space and save the labor of supervising the
working of the same.
My Invention is applicable either for adapting one of the pulls of an existing
beer engine, or for constructing a new engine for aerating and delivering this kind
of beverage.
In carrying out my invention, I adapt the pump of one of the pulls of an engine
to pump air under pressure into the beer cask, or into an intermediate air vessel,
as the case may be, by providing the pump barrel with a suitable air inlet and pipe
connection with the air vessel or cask, said inlet and connection being controlled by
suitable check valves. The draw-off spout is disconnected from the pump barrel
and connected with the delivery pipe of the ordinary fitting used for Lager Beer
casks, the said pipe passing through a refrigerating chamber situated beneath the
casing of the beer engine, or in other convenient place.
The stop cock is fitted upon this pipe in an accessible position in front of the
engine, if the delivery spout is not already provided with one, for the purpose of
controlling the delivery of the beer. The air inlet and pipe connection may be
made with either end of the pump barrel, but preferably in the case of existing
engines, with the upper end in order that the delivery stroke of the air pump may
take place at the forward pull of the handle. Or the pump cylinder might be
inverted and its piston connected with the pull lever by a cross head and links.
Or the leverage of the pull handle might be modified to produce the same result.
By means of my Invention it is only necessary to use the beer pull in the
ordinary way from time to time to charge the cask from the air vessel, if one is
used.

Improvements in Beer Engines for Aerating and Retailing Lager
1 and other Beers.
I, THOMAS FITZROY KELLY of 138 Victoria Park Road, South Hackney in the
County of Middlesex Brewers Engineer do hereby declare the nature of the said
invention for." IMPROVEMENTS IN BEER ENGINES FOR AERATING AND RETAILING
LAGER AND OTHER BEERS" and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:—
Heretofore special and expensive machinery has been required for aerating and
pumping lager beer and such machinery consisting of pump. air vessel &c has
usually been located in the cellar or other place distant from the point of delivery.
and has usually necessitated the services of a special attendant to keep the apparatus
charged and in working order.
My invention has for its object to adapt the ordinary beer engine to the purpose
of retailing Lager Beer and similar beverages, and thereby to reduce the cost of
machinery, economise space and save the labour of supervising the working of the
same.
My invention is applicable either for adapting one of the pulls of an existing
beer engine to the purpose of aerating and delivering this kind of beverage or for
constructing a new engine for the purpose.
Reference is to be had to the accompanying drawings forming part of this Speci-
fication wherein figure 1 represents a cross section of a bar or counter showing one
of the pulls of an ordinary beer engine applied to the purpose of retailing lager
beer and showing also the disposition of the compressed air chamber and refri-
gerating coil beneath the counter. Figure 2 is a front elevation of the same. The
arrangements shown in figures 1 and 2 are such as would be adopted if it be desired
to use one of the pulls and delivery spouts of an existing engine for drawing lager
beer.
Figures 3 and 4 are similar views showing the arrangements in the case when a
special standard fixed on the counter is used, instead of the beer engine spout, and
showing also the pipe connections with the cask.
Referring to figures 1 and 2, which show the method of carrying out my
invention as applied to an existing beer engine, I adapt the pump of one of the
pulls of the engine to pump air under pressure into the beer cask or preferably
into an intermediate air vessel a, by connecting the pump barrel b with the air
vessel a (or directly with the upper part of the cask) by means of a pipe c, the
former connection of the lower end of the barrel with the suction pipe serving as
the air inlet, and the valves seated respectively in the bottom of the barrel and in
its piston, serving as check valves.
The pipe c may also be fitted with a check valve or it may have a cock d upon
it. The draw off spout e is disconnected from the pump barrel b and connected
with the delivery pipe f of the ordinary fitting used for Lager Beer casks (shown
in figure 3) the said pipe in the form of a coil passing through a refrigerating
chamber g situated beneath the casing of the beer engine or in other convenient

page_text: place. The air vessel a is connected with the said fitting by the air delivery pipe h
provided with a stop cock i
A stop cock k is fitted upon the pipe fin an accessible position.in front of the
engine, if the delivery spout e is not already provided with one, for the purpose of
controlling the delivery of the beer. The pipe c may be in connection with either
end of the air pump barrel, but preferably in the case of existing engines, with the
upper end, in order that the delivery stroke of the air pump may take place at the
forward pull of the handle. Or the air pump cylinder 6 might be inverted and its
piston connected with the pull lever by a cross head and links. Or the leverage of
the pull handle might be modified to produce the same result.
Referring to figures 3 and 4 showing the apparatus as constructed expressly for
the purpose, the pump barrel b has a solid piston and air holes in the bottom and
is connected at its upper end with inlet and outlet check valve boxes, the latter
being connected by pipe c with the air vessel a The other connections are the
same as before, the only difference being, that in this case, a special standard s
fitted with the usual cocks, is used instead of the spout e.
attached to the cask is of the usual construction, the connection of the air delivery
The fitting shown as
pipe with the cask being through an external annular thoroughfare and that of
the beer pipe f being through the centre and passing down nearly to the bottom of
the cask.
Whichever form of apparatus be used, it is only necessary to use the beer pull ?
in the ordinary way from time to time, to charge the cask or the air vessel, if one is
used; a manometer fixed near the beer pull in the bar, indicating when pressure is
required.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
The combination with the pull handle of a beer engine, of a. pump adapted to
pump and compress air, and of an air vessel and fittings for conveying the air to
the cask and discharging the beer therefrom substantially as shown and described.
