page_text: LETTERS PATENT to Riley Hargreaves and James Bardsley, both of Oldham,
in the County of Lancaster, Brassfounders, for the Invention of " IMPROVE.
MENTS IN BEER PUMPS OR APPARATUS FOR RAISING OR DRAWING OFF
LIQUORS."
Sealed the 4th October 1878, and dated the 16th April 1878.
PROVISIONAL SPECIFICATION left by the said Riley Hargreaves and James
Bardsley at the Office of the Commissioners of Patents on the 16th April
1878.
RILEY HARGREAVES and JAMES BARDSLEY, both of Oldham, in the County of
Lancaster, Brassfounders. "IMPROVEMENTS IN BEER PUMPS OR APPARATUS FOR
RAISING OR DRAWING OFF LIQUORS."
Our Invention relates to the beer pumps principally employed in the drawing
off of such liquors as ale and stout. The said beer pumps are connected by means
of pipes with the casks of liquor which are at a lower level, so that the liquor has
to be raised by the action of the pumps, as is well understood. The liquor is dis-
charged from each pump through a bib or spout, and this bib is usually provided
with a tap, which can be closed after the quantity of liquor required at any time
has been obtained.
Previously to our said Invention the said tap has been closed by hand by an
operation distinct from the operation of raising the liquor.
Our said Invention has for its object to effect the opening and closing of the tap,
or of a tap or valve substituted therefor, by the ordinary operation of the handle or
"pull." To this end we so connect the plug of a stop tap or the spindle of a stop
valve with the said handle or pull, or with a link or part connected therewith, as
that when the pull is operated to discharge the liquor the said tap or valve is opened
to permit such discharge.
In one arrangement a tap is fitted to the pipe or passage leading to the bib, and
on the plug or spindle of the said tap a slotted lever is fixed. A pin or projection

page_text: fixed on the link, or on one of the links which connect the pull lever with the
pump rod works in the slot of the said lever. The form of the said lever and the
adjustment of the parts are so regulated as that when the pull is actuated to
draw the liquor the tap is opened before the pump piston is raised to any great
extent.
The arrangement may be greatly varied, as for example, the tap or valve may be
acted upon by a spring or weight which tends to open the passage and be closed
when the pull is pushed back, or be acted upon by a spring or weight which tends
to close the passage and be opened when the pull is drawn forwards, and also in
lieu of the pin on the pump link a pin on the pull lever may work in a curved
slotted lever fixed to the tap plug or arranged to open the valve, or the tap or valve
may be operated upon by a curved incline or slotted quadrant fixed to or formed on
the said pull lever.
In lieu of a plug tap we may employ a tap or valve having a disc which by its
rotation covers and uncovers a passage leading from the pump to the discharge bib.

the said Riley Hargreaves and James Bardsley in the Great Seal Patent
Office on the 16th October 1878.

Our said Invention has for its object to effect the opening and closing of the tap
or of a tap or valve substituted therefor by the ordinary operation of the handle or
pull." To this end we so connect the plug of a stop tap or the spindle of a stop
valve with the said handle or pull, or with a link or part connected therewith, as
that when the pull is operated to discharge the liquor the said tap or valve is
opened to permit such discharge.
And in order that our Invention may be fully understood we have appended
hereunto a Sheet of Drawings, made about three quarters of the full size, and marked
with letters of reference, to which Drawings we will now refer.

page_text: Fig. 1 represents so much of a beer engine as is necessary to the illustration of
our Invention.
In the said Figure a is the piston rod of the pump barrel; 6 represents the lower
b
part of the "pull" or handle; c is the stop tap or valve; and d is the bib or
spout.
The stop tap c may be of any ordinary or suitable construction, or may be formed
in the manner indicated by Fig. 2, which represents the valve employed in the
example selected for illustration, the said Figure being drawn partly in section. . A
disc e is arranged, and ground, and finished to fit in a suitably fluid-tight manner
against a valve face formed in the casting c. A spindle fis fitted to revolve in the
said casting, and on the inner end of the said spindle is mounted the disc e, so that
the said disc can be rotated to the required extent by turning the said spindle. A
port g is formed in the said disc, as also indicated by dotted lines in Fig. 1, and a
passage his formed in the casting and leads to the delivery bib or spout d.
spiral spring i presses the disc against its seating. The liquor from the pump barrel
flows to the valve through a pipe and branch k. To the spindle fis fixed a slotted
lever . In the example the said lever is formed with a shank, which passes
through a head formed on the said spindle, and is secured by means of a set
screw m.
A
The piston rod of the pump is connected with the lower end of the pull or handle
by means of a link n, as is usual. To or on this link is fixed or formed a stud or
pin o, which enters the slot in the lever l.
The arrangement might be so varied as that the stud would be fixed on the lower
end of the pull lever, or be an extension of the joint pin.
When the pump piston is at rest in its lowest position the parts are in the
positions indicated by the full lines in Fig. 1, and the passage through the valve c
is closed by reason of the passage h being covered by the disc. The flow of the
liquor or froth through the valve is thus prevented. When the handle is pulled
forwards to draw off liquor the pin or stud o acts upon the lever so as to turn
the spindle whereby the disc valve is rotated, and the port therein is brought into
communication with the passage h.
As the first movement of the pull-acts to move the upper end of the link n' in
the direction indicated by the arrow, the pin o acts immediately upon the lever to
open the valve, and as at the commencement of such movement the pump rod is
very slightly moved, the valve commences to open in time to permit the flow of
liquor from the pump, supposing the parts to have been suitably adjusted. The
continued movement of the link n rapidly opens the valve so that the area of the
passage through the valve increases as the flow of the liquor increases.
The dotted lines in Fig. 1 indicate the positions of the link and slotted lever
when the handle is pulled fully over. The bib or spout d may be of any suitable
form, and the parts not represented may be of any ordinary or suitable construction.
The details of the arrangement may be greatly varied, as, for example, in lieu of
the slotted lever the link n may be slotted and formed to act upon a stud fixed to
the valve lever, the effect being the same as in the example illustrated.
Other modifications may also be made in the arrangement. The tap or.valve
may be acted upon by a spring or weight, which tends to open the passage, the link
n acting to close the valve when the pull is pushed back, or the spring or weight
may tend to close the valve, the said link opening the valve when the pull is drawn
forwards, or the tap or valve may be operated upon by a curved incline or slotted
quadrant fixed to or formed on the pull lever; or other arrangements may be adopted
so long as the valve is opened when the pull is drawn forwards without requiring
separate action on the part of the operator. A plug tap or any suitable form of tap
or valve may be used in lieu of the valve d.
Having now fully set forth and indicated the nature of our said Invention, and
the manner in which we carry the same into effect, we would have it to be understood
in conclusion that we claim,-
First. The arrangement and combination of parts substantially as and for the pur-

page_text: 'pose set forth and indicated herein-before, and in and by the accompanying
Drawings.
Secondly. The lever fixed to the spindle or plug of a valve or tap, and acted upon
by the link or by the "pull lever," or by a part connected therewith, substantially
as and for the purpose set forth and indicated.
Thirdly. The valve, substantially as and for the purpose set forth and indicated
with reference to Fig. 2 of the accompanying Drawings.
And, lastly, the employment of a valve tap or cock arranged to be opened self-
actingly when the pull or handle is acted upon to draw off liquor, and to be closed
when the said pull is returned to its position of rest.
In witness whereof, I, the said James Bardsley, for myself and on behalf of
the said Riley Hargreaves, have hereunto set my hand and seal, the
Fifteenth day of October, in the year of our Lord One thousand eight
hundred and seventy-eight.
