IMPROVEMENTS IN THE CONSTRUCTION OF PUMPS FOR RAISING AND FORCING BEER AND OTHER LIQUIDS
Year: 1872

page_text: LETTERS PATENT to John George Frei, of King Street, Snow Hill,
in the City of London, Pewterer, and George Kember, of North-
ampton Street, Clerkenwell, in the County of Middlesex, Brass-
founder, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF
PUMPS FOR RAISING AND FORCING BEER AND OTHER LIQUIDS."
Sealed the 3rd September 1872, and dated the 6th March 1872.
PROVISIONAL SPECIFICATION left by the said John George Frei and
George Kember at the Office of the Commissioners of Patents, with
their Petition, on the 6th March 1872.
We, JOHN GEORGE FREI, of King Street, Snow Hill, in the City of
London, Pewterer, and GEORGE KEMBER, of Northampton Street,
Clerkenwell, in the County of Middlesex, Brassfounder, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE CON-
STRUCTION OF PUMPS FOR RAISING AND FORCING BEER AND OTHER LIQUIDS," to be
as follows:-
This Invention consists in the construction of beer and other pumps
whereby much time and labour are saved. An ordinary cylinder of any

page_text: desired size is provided with two suction and two delivery pipes, which
are respectively placed at the top and bottom of the cylinder. Each of
these pipes is provided with a valve of any ordinary and suitable
description for the purpose of regulating the flow of the liquid. In the
cylinder a piston rod provided with a solid piston head works, which
piston is actuated by the handle of the pump in the ordinary manner.
When it is desired to raise the liquid the piston is raised by drawing
down the handle of the pump, thus causing a vacuum in the lower part
of the cylinder, which vacuum is displaced by liquid admitted through
the suction pipe at the bottom of the cylinder. The piston is then
lowered, forcing the liquid contained in the lower part of the cylinder
up through the lower delivery pipe, and causing a vacuum in the upper
part of the cylinder above the piston head, which vacuum is displaced
by liquid admitted through the upper suction pipe. By this means
double the quantity of liquid can be raised at each stroke of the piston
than by the pumps as constructed at present.
1
The two suction pipes may be made to supply two different liquids
such as ale and stout, and the two delivery pipes may either be brought
to one tap and the liquids mixed as they issue therefrom, or they may
be carried to separate taps, in which case the liquids may be delivered
separately.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John George Frei and George Kember in the Great
Seal Patent Office on the 6th September 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
GEORGE FREI, of King Street, Snow Hill, in the City of London,
Pewterer, and GEORGE KEMBER, of Northampton Street, Clerkenwell,
in the County of Middlesex, Brassfounder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her.
Letters Patent, bearing date the Sixth day of March, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said John George Frei and George Kember, Her
special licence that we, the said John George Frei and George Kember,
our executors, administrators, and assigns, or such others as we, tlie :

page_text: said John George Frei and George Kember, our executors, adniinis-
trators, 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 PUMPS FOR RAISING AND FORCING BEER AND OTHER LIQUIDS," upon
the condition (amongst others) that we, the said John George Frei
and George Kember, 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 performed, 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 John George Frei and George
Kember, 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 in the construction of pumps for raising
and forcing beer and other liquids whereby much time and labour are
saved. We provide the cylinder of the pump, which may be of any
desired size, and of the ordinary description, with two suction and two
delivery pipes, which we respectively place at the top and bottom of the
cylinder, that is to say, one suction and one delivery pipe in that part of
the cylinder which is below the piston head, and one suction and one
delivery pipe in that part of the cylinder which is above the piston
head, and which suction and delivery pipes are provided with a valve or
valves of any ordinary and suitablé description for the purpose of
regulating the flow of the liquid. In the cylinder a piston rod pro-
vided with a solid piston head works, which piston is actuated in the
ordinary manner. When it is desired to raise the liquid the piston is
lifted in the ordinary manner, thus causing a vacuum in the lower part
of the cylinder, and which vacuum is displaced by the liquid admitted
through the suction pipe at the lower end of the cylinder. The piston
is then lowered, forcing the liquid in the lower part of the cylinder up
through the lower delivery pipe, and at the same time causing a vacuum

page_text: A is the cylinder; B, the enlarged piston rod carrying the solid piston
head ; C, the lower suction pipe for the admission of the feed water
into the cylinder; and D, the lower delivery pipe; E is the upper
suction pipe, and F the upper delivery pipe, which is shewn as con-
nected with the lower delivery pipe D by means of the delivery passage
G; but when it is desired to deliver the two liquids separately, the
delivery passage G may be dispensed with and the cap / removed from
the delivery pipe F, which can then be extended as may be desired.
Having thus described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we would
observe in conclusion that what we consider novel and original, and
therefore claim as constituting the Invention secured to us by the said
herein-before in part recited Letters Patent is, the construction of double
action pumps in the manner and for the purposes herein-before set forth
and described, or any mere modifications thereof.
In witness whereof, we, the said John George Frei and George
Kember, have hereunto set our hands and seals, this Fifth day
of September, in the year of our Lord One thousand eight hundred
and seventy-two.
