PROVISIONAL SPECIFICATION.
Improvements in Beer Engines and Pumps.
I JAMES BARDSLEY of the firm of Hargreaves and Bardsley, of the Union
Brass Works, Oldham, in the County of Lancaster, Brass Founder and Finisher
do hereby declare the nature of this invention to be as follows:-
My said invention relates to the construction of beer engines and pumps from a
new material. As at present constructed such beer engines and pumps are made
of brass with the result that the interior of the brass pump barrel being con-
tinually subject to friction has a deteriorating effect upon the liquor especially
when the beer has been allowed to stand for some length of time in the pump.
To obviate this defect it has been proposed to make the pump cylinders of glass
but the difficulties of manufacturing and using so fragile a material have proved
almost insuperable..
Now according to my invention I make the pump barrel of stone ware, this
material being absolutely tasteless and not affecting in any degree the liquor
passing through the pump. In addition to this pump barrels of stone ware are
easily made and are not so sensible to changes of temperature nor are they so
fragile as glass pumps. The beer is kept cooler and in perfect condition no matter
how long it may stand in the pump. Not only the pump barrel but the plunger
and all parts of the pump or engine which it may be considered desirable to
make of stone ware may be so made.
The construction and proportions of the pumps or engines may be varied or
modified in various ways so long as the principle of my invention is adhered to,
which is the employment of stone ware in the manufacture of beer pumps and
engines.

Improvements in Beer Engines and Pumps.
I JAMES BARDSLEY of the firm of Hargreaves and Bardsley, of the Union
Brass Works, Oldham, in the County of Lancaster, Brass Founder and Finisher,
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 that is to say :-
My invention relates to the construction of parts of beer engine pumps from a
new material. As at present constructed beer engine pumps are made of brass
with the result that the interior of the brass pump barrel being continually subject
to friction has a deteriorating effect upon the liquor especially when the beer has
been allowed to stand for some length of time in the pump. To obviate this defect
it has been proposed to make the pump cylinders of glass but the difficulties of
manufacturing and using so fragile a material have proved almost insuperable.
According to my invention I make the pump barrel of stone ware, this material
being absolutely tasteless and neutral and not affecting in any degree the liquor
passing through the pump. In addition to this, pump barrels of stone ware are
easily made and are not so sensible to changes of temperature nor are they so
fragile as glass pumps. The beer is kept cooler and in perfect condition no matter
how long it may stand in the pump. In practice I have found the most suitable

material to be the description of earthenware which is termed mortar-ware.
make the barrels of such ware and I bore them to a true cylindrical internal form
before firing. I find them to be sufficiently true after the firing but if it is
necessary I should grind them after firing to bring them to the true cylindrical
formation. Not only the pump barrel but the bucket or piston and all parts of the
pump or engine which it may be considered desirable to make of stone ware may be
so made.
At present however I am of opinion that only the parts which are exposed
to friction need be made of stone-ware as parts not so exposed acquire a pro-
tective coating when the pump has been used for some time. If considered to be
desirable parts not exposed to friction might be enamelled. I may coat the piston
rod with vitreous enamel or make the rod of an alloy which will not have an
injurious effect upon the liquor. Although I have referred only to the ordinary
construction having a cylinder and piston I do not exclude pumps of other
formations as earthenware rams working in packed glands might be used if con-
sidered to be desirable.
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. The beer pump barrel made of stone-ware as set forth.
2. Making parts of beer engine pumps of stone-ware as and for the purpose set
forth.
