COMPLETE SPECIFICATION.
Improvements in or relating to Beer Engines, and the Nozzles or
Spouts from which the Beer is Drawn.
I FRANCIS HENRY MATHEWS of 84 Walworth Road, in the County of
London, Pewterer and Beer Engine Manufacturer, 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 :-
Hitherto in beer engines, as at present constructed, there has been much waste,.
on account of the beer running from the nozzle, or spout (after drawing); the
piston rod passes into the barrel of engine and displaces the beer therein forcing a.
portion out of the nozzle or spout.
Now in order to obviate the above loss, I construct a beer engine as follows,.
reference being had to the sheet of drawings accompanying this Specification, in
which
Fig. 1 shews vertical section of beer engine constructed according to this.
invention, and
Fig. 2 section of spout or nozzle with my improvements adapted thereto.

The spout or nozzle k (Fig. 2) is provided with a series of partitions tubes or
holes and gauze in order to retain the liquid in its position after the closing of
valve h. m is a forked lever, the upper end of which is connected to the ordinary
handles or levers to actuate the piston b, and rod c. n is a tube, this may either be
fixed over the suction valve g, as shewn, or in the cellar in order to prevent
back flow in fast working of the engine by the air contained in such tube acting on
the surface of the beer and thus forming an elastic cushion.
The drawing as shewn is, with the handle or lever of the engine down, the beer
just having been discharged.
The action is as follows:-
The position of the valve e before being actuated is at the bottom of the
barrel a, the beer is then in the top part of the barrel above the bucket
valve e, and all the valves closed. When it is desired to draw the beer the
lever on the counter (not shewn) is pulled down raising the piston b (by means
of the fork m) forcing the beer to open the valve h and discharge itself; also at
the same time filling the barrel below the bucket valve e (the valve g. being opened
by suction) with beer; when the lever is pushed back into its normal position, the
beer opens the valve e and passes above the said valve ready for another discharge.
and so on.
It will easily be seen by the above, that the displacement of liquid which occurs.
by the piston or rod being placed at the top in the usual manner, is prevented;
as after the lever is pulled down to draw the beer in the usual way, it is pushed.
back and the piston rod following into the barrel displaces the liquid which causes
it to run to waste from the nozzle or spout of the engine.
The spout shewn in Fig. 2 has a number of tubes fitted therein, also a piece of
wire gauze, these I may use in combination or separately when thin beer is to be
drawn; but for thick beer I may dispense with the gauze, these tubes and gauze
are used to prevent dripping from the nozzle.

page_text: 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 :-
1. In beer engines the inverted piston, and the position of the valve g and e.
2. In beer engines the use of valve h for the purpose set forth.
3. In beer engines the use of a tube n for the purpose set forth.
4. In the employment of tubes, and gauze in the spouts or nozzles of beer engines,
either separately, or combined, for the purpose set forth.
5. In beer engines the general construction, and arrangement of parts sub-
stantially, as herein before described, and shewn on the accompanying drawing.
Dated this 10th day of February 1894.
