IMPROVEMENTS IN THE CONSTRUCTION OF HYDRO-BEER PUMPS
Year: 1864

page_text: LETTERS PATENT to William Jackson, of Sunderland, in the County of
Durham, Engineer, and John Glaholm and William Glaholm, of Bishop-
wearmouth, in the said County, Brass Founders, for the Invention of
PROVISIONAL SPECIFICATION left by the said William Jackson, John
Glaholm and William Glaholm at the Office of the Commissioners of
Patents, with their Petition, on the 29th November 1864.
We, WILLIAM JACKSON, of Sunderland, in the County of Durham, Engineer,
and JOHN GLAHOLM and WILLIAM GLAHOLM, of Bishop-wearmouth, in the said
County, Brass Founders, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF HYDRO-BEER PUMPS," to be as
follows:-
This Invention consists of certain improvements in the construction of
pumps for drawing beer from the barrels in which it is contained, whereby
that beverage is delivered in a fresher and brisker condition than by the
pumps and engines hitherto used for the like purpose.
Two modes of construction are adopted. In the first, the pump consists of
a cylinder mounted in and fixed to a suitable frame, in which cylinder works
a solid plunger, connected with and actuated by a lever in the ordinary way.
At the bottom of the cylinder is placed an outlet pipe communicating with
the tap for the delivery of the beer, the same being fitted with a suitable

page_text: valve. At the bottom of the cylinder is also placed the suction valve, by
which, upon the rising of the plunger, the beer is admitted from the suction
pipe into the cylinder. The valve seats are so tapered as to present only a
thin edge to the faces of the valves, the object of this mode of construction
being to prevent the valves being clogged by the resting of any hop or other
matters on the the faces thereof. Upon the plunger being raised the beer is
drawn through the suction pipe into the cylinder, from which it is expelled
through the delivery valve by the downward stroke of the plunger, the
cylinder being thus filled and completely emptied by each elevation and
depression of the plunger.
The foregoing description will be more clearly understood by reference to
the accompanying Drawing.
A is the cylinder, and a the plunger; B is the suction pipe; C is the outlet
where the tap is affixed; D is the delivery valve, baving a spiral or other
spring to keep it up to the valve seat F, F; E is the suction valve, F*, F*,
being the valve seat, which, as well as the seat of the delivery valve is made
taper, as before described; G is a hole in the bottom of the cylinder for the
outlet; H is a nut on the part connected with the suction pipe, and by which
the cylinder is fastened to its frame; I, I, are nuts on the suction valve, one
to fasten leather on to the face thereof, and the other to prevent the valve
from rising out of its seat; K, K, is a recess in the cylinder end, to facilitate
the falling off of any matters from the face of the valve.
In
Instead of constructing the pump as herein-before described, the arrange-
ment of the parts may be varied, so that the cylinder itself shall be actuated
instead of the plunger. The upper end of the cylinder is closed, and the
working rod which is connected with the actuating lever is fixed in the centre
of the top plate of the cylinder, which latter is open at the bottom, but having
a tap attached thereto with an outlet valve for the delivery of the beer.
lieu of the ordinary plunger a pipe is fixed to the frame to which the pump
is attached, the same having a head constructed so as to fit the interior of the
cylinder, in the same way as the common plunger. The suction valve is
placed in the centre of the head at the top of the pipe, the suction pipe being
attached to the lower end thereof. Upon the cylinder being raised by the
actuating lever, the beer will be drawn through the suction valve, while by the
depression of the cylinder the beer will be forced through the outlet valve,
and delivered by the tap.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Jackson, John Glaholm, and William Glaholm in
the Great Seal Patent Office on the 29th May 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
JACKSON, of Sunderland, in the County of Durham, Engineer, and JOHN.
GLAHOLM, and WILLIAM GLAHOLM, of Bishop-wearmouth, in the said County,
Brass Founders, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of November, in the year of our,
Lord One thousand eight hundred and sixty-four, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said William Jackson, John Glaholm, and William Glaholm, Her special
licence that we, the said William Jackson, John Glaholm, and William
Glaholm, our executors, administrators, and assigns, or such others as we,
the said William Jackson, Johu Glaholm, and William Glabolni, our,
executors, administrators, and assigns, should at any time agree with, and
no others, from time to time, and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE CON-
STRUCTION OF HYDRO-BEER PUMPS," upon the condition (amongst others) that
we, the said William Jackson, John Glaholm, and William Glaholm, our
executors, or administrators, by an instrument in writing under our, or their,
or one of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said William Jackson, John Glaholm, and
William Glaholm, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the
Drawings hereunto annexed, and to the figures and letters marked thereon
(that is to say) :-
Our said Invention consists of certain improvements in the construction of
pumps for drawing or raising beer from the barrels or receptacles in which it
is contained, and whereby that beverage is delivered in a fresher and brisker

page_text: condition than by the pumps and engines hitherto employed for the like
purpose.
The pump consists of a cylinder mounted in and fixed to a suitable frame,
in which cylinder works a solid plunger, connected with and actuated by a
lever in the ordinary way. At the bottom of the cylinder is placed an outlet
pipe communicating with the tap for the delivery of the beer, the same being
fitted with a suitable valve. At the bottom of the cylinder is also placed the
suction valve, by which, upon the rising of the plunger, the beer is admitted
from the suction pipe into the cylinder. The valve seats are so tapered as to
present only a thin edge to the faces of the valves, the object of this mode of
construction being to prevent the valves being clogged by the resting of any
extraneous matters upon the faces thereof, and which might impede or
interfere with the proper operation of the pump. Upon the plunger being
raised the beer is drawn through the suction pipe into the cylinder, from
which it is expelled through the delivery valve by the downward motion of
the plunger, the cylinder being thus filled and completely emptied by each
elevation and depression of the plunger.
The foregoing description of our said Invention will be more clearly and
fully understood by reference to the accompanying Drawings.
In Figure 1, A is the cylinder, and a the plunger; B is the suction pipe;
C is the suction valve, c, c, being the valve seat, which, as well as the seat of
the delivery valve is made taper, as before described; D is a nut on the part
connected with the suction pipe, and by which the cylinder is fastened to its
frame; d, d, are nuts on the suction valve, one to fasten leather on to the
surface thereof, and the other to prevent the valve from rising out of its seat;
E, E, is a recess in the cylinder end. to facilitate the falling off of any
extraneous matters from the face of the valve; F is an opening at the bottom
of the cylinder for the outlet; G is the delivery valve, having a spiral or
other spring to keep it up to the valve seat 9, 9; H is the outlet where the
tap is affixed, If preferred, the delivery valve may be constructed and
arranged as shewn in Figure 2 at A.
It is obvious that although the pump herein-before described is intended,
and is especially adapted for the purpose of drawing or raising beer, as
aforesaid, it is also applicable to other liquids.
Having thus fully described and ascertained the nature of our said Inven-
tion, and also the manner in which it is to be performed, we would observe in
conclusion that we do not claim the several and distinct parts of the apparatus
herein-before described separately and apart from each other as being of our
Invention; but what we consider novel and original,. and therefore claim as

page_text: constituting our said Invention is, the arrangement and combination of parts
and mechanism for effecting the purposes aforesaid, as herein-before sub-
stantially described and set forth, or any mere modifications thereof.
In witness whereof, we, the said John Glaholm and William Glaholm,
on behalf of ourselves and the said William Jackson, have hereunto
set our hands and seals, this Twenty-sixth day of May, in the year
of our Lord One thousand eight hundred and sixty-five.
