Year: 1874

page_text: LETTERS PATENT to Henry Boyland Wilsher, of the Town and County
of Newcastle-upon-Tyne, Engineer, for the Invention of "IMPROVE-
MENTS IN APPARATUS FOR WITHDRAWING BEER OR OTHER LIQUIDS PRom Casks
OR OTHER VESSELS."
Sealed the 14th August 1874, and' dated the 1st May 1874.
PROVISIONAL SPECIFICATION left by the said Henry Boyland' Wilsher
at the Office of the Commissioners of Patents, with his Petition,
on the 1st May 1874.
I, HENRY BOYLAND WILSHER, of the Town and County of Newcastle-
upon-Tyne, Engineer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN APPARATUS FOR WITHDRAWING BEER OR OTHER
LIQUIDS FROM CASKS OR OTHER VESSELS," to be as follows:-
This Invention has for its object improvements in apparatus for
withdrawing beer or other liquids from casks or other vessels, and
relates to the arrangement of apparatus for this purpose in such manner
as to make one pump serve for withdrawing liquid' from a number of

page_text: casks or vessels, thus dispensing with the use of a separate pump for
each cask or vessel as has heretofore been usual. To this end I
arrange
the pump with its barrel in communication with a space or chamber
provided with as many orifices as there are casks or vessels from which
liquid is to be drawn. Each of these orifices is provided with a suitable
valve arranged to close automatically by a spring or otherwise, but
capable of being opened at will by a treadle, or lever, or other suitable
means. Each of the said orifices when open establishes a communication
between the space or chamber above mentioned and one of the casks or
vessels. The pipe leading to each cask or vessel is furnished with a
back pressure valve to prevent return of liquid to the cask or vessel.
There is also a spout or eduction pipe from the space or chamber above
mentioned for the escape of the liquid therefrom, and this spout or
eduction pipe is furnished with a valve opening outwards.
When beer or liquid is to be withdrawn from any one of the casks or
vessels the corresponding valve is opened by means of the treadle or
equivalent arrangement, thus placing the space or chamber at foot of
the pump barrel in communication with the pipe leading to the cask or
vessel from which liquid is to be withdrawn. On now drawing up the
pump piston or plunger a partial vacuum is created in the said space or
chamber, and thereby liquid is drawn into it from the cask or vessel.
The valve leading to that cask or vessel is now allowed to close, and on
the return stroke of the pump the liquid just drawn into the space or
chamber is forced out through the spout or eduction pipe into any
suitable measure or vessel placed to receive it.
Another part of my Invention relates to making the pump barrel and
piston rod in the form of an arc of a circle, the piston rod being provided
with an arm working on a suitable centre picce or pin. .

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of May, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors;
give and grant unto me, the said Henry Boyland Wilsher, Her special
license that I, the said Henry Boyland Wilsher, my executors, admini-
strators, and assigns, or such others as I, the said Henry Boyland Wilsher,
my 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 "IM-
PROVEMENTS IN APPARATUS FOR WITHDRAWING BEER OR OTHER LIQUIDS FROM
CASKS OR OTHER VESSELS," upon the condition (amongst others) that I,
the said Henry Boyland Wilsher, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals;
should particularly describe and ascertain the nature of the said Inven-
tion, 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 I, the said Henry Boyland Wilsher, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement thereof and the Drawings therein referred to
(that is to say)-
This Invention has for its object improvements in apparatus for with-
drawing beer or other liquids from casks or other vessels, and relates to
the arrangement of apparatus for this purpose in such manner as to
make one pump serve for withdrawing liquid from a number of casks or
vessels, thus dispensing with the use of a separate pump for each cask
or vessel as has heretofore been usual. To this end I arrange the pump
with the barrel in communication with a space or chamber provided
with as many orifices as there are casks or vessels from which liquid is
to be drawn. Each of these orifices is provided with a suitable valve,
arranged to close automatically by a spring or otherwise, but capable of
being opened at will by a treadle, or lever, or other suitable means.
Each of the said orifices when open establishes a communication between

page_text: the space or chamber above mentioned and one of the casks or vessels.
The pipe leading to each cask or vessel is furnished with a back pressure
valve to prevent return of liquid to the cask or vessel. There is also a
spout or eduction pipe from the space or chamber above mentioned for
the escape of the liquid therefrom, and this spout or eduction pipe is
furnished with a valve opening outwards.
When beer or liquid is to be withdrawn from any one of the casks or
vessels the corresponding valve is opened by means of the treadle or
equivalent arrangement, thus placing the space or chamber at foot of
the pump barrel in communication with the pipe leading to the cask or
vessel from which liquid is to be withdrawn. On now drawing up the
pump piston or plunger a partial vacuum is created in the said space or
chamber, and thereby liquid is drawn into it from the cask or vessel,
The valve leading to that cask or vessel is now allowed to close, and on
the return stroke of the pump the liquid just drawn into the space or
chamber is forced out through the spout or eduction pipe into any
suitable measure or vessel placed to receive it.

Another part of my Invention relates to making the pump barrel and
piston rod in the form of an arc of a circle, the piston rod being provided
with an arm working on a suitable centre piece or pin.

Such being the nature of my said Invention I now proceed to describe
the manner of carrying the same into practical effect with reference to
the accompanying Drawings, wherein Fig. 1 shews my improved
apparatus in front élevation; Fig. 2 is a vertical section on the line
A, B, of Fig. 1; and Fig. 3 is a plan.

* . .I
The pump barrel a communicates with the space or chamber 6 pro-
vided with orifices c, each connected by a separate pipe c with a distinct
cask or vessel from which liquid is to be withdrawn, four being shewn
in the apparatus illustrated; each orifice c is provided with a valve d
closing against a seat e; the valves of the upper orifices are pressed
against their seats by spiral springs f; the valves of the lower orifices
are closed against their seats by the action of a weight g suspended from
a pulley. h held by a cord or connection i whose ends are secured to two
crank levers k, k³, each connected to the stem of the corresponding
lower valve; the valve stems 7 pass through glands or stuffing boxes m,

page_text: and their outer ends are connected by cords or connections n passing
over pulleys o to treadles p having their fulcra at p; q is a spout or
eduction pipe which is furnished with a ball valve r opening outwards;
s are back pressure valves.
.I. 1
Assuming each of the pipes c¹ to be connected with a separate cask or
vessel it will be evident that on depressing any one of the treadles P and
drawing forward the pump handle liquor from the cask or vessel corre-
sponding to the treadle depressed will be drawn into the space or
chamber b and barrel a, and that on the treadle being then released so
as to allow its valve to close and the pump handle returned to the
position shewn in Fig. 2 the liquor just drawn into the said space or
chamber will press open the valve and escape by the spout q. Thus
by the peculiar combination with the pump barrel of the space or
chamber 6 with its valves and their operating apparatus the one pump
is made to do all the work for which in an ordinary beer engine as many
separate pumps would be required as there are orifices c and valves d to
the space or chamber 6 in my apparatus. No liquor remains in the
barrel of the pump, and it is capable of being moved from place to place
besides taking up less room than apparatus of the ordinary kind.
°
It will be evident that by releasing one treadle and depressing another
during the forward stroke of the pump liquor from two or more distinct
casks or vessels may during a single stroke of the pump be drawn up
into and mixed in the space or chamber and barrel a.
Having described the nature of the said Invention, and having
explained the manner of carrying the same into practical effect, I hereby
declare what I consider to be novel and original and therefore claim as
the Invention secured to me by the herein-before in part recited Letters
Patent to be,
First. Adapting a single pump to withdraw liquid from two or more
casks or vessels by combining with the pump barrel a space or chamber
communicating independently with each cask or vessel by pipes or
connections provided with valves, operated substantially as and for the
purposes specified..

with reference to the accompanying Sheets of Drawings.
In witness whereof, I, the said Henry Boyland Wilsher, have here-

unto set my hand and seal, this Twenty-second day of October,
in the year of our Lord One thousand eight hundred and seventy-
four.
HENRY BOYLAND WILSHER. (L.S.)
