Year: 1837

page_text: SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
STOCKER, of Bristol, Gentleman, send greeting.
WHEREAS His late most Excellent Majesty King William the Fourth, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fourth day of March, in the seventh year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said
Samuel Stocker, His especial licence, full power, sole privilege and authority,
that I; the said Samuel Stocker, my exors, admors, and assigns, or such others
as I, the said Samuel Stocker, my exors, adiñors, or assigns, should at any
time agree with, and no others, from time to time, and at all times during the
term of years therein expressed, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "IMPROVEMENTS ON PUMPS;" in which said Letters Patent is
contained a proviso, that I, the said Samuel Stocker, shall cause a particular
description of the nature of my said Invention, and in what manner the same
is to be performed, to be inrolled in His said Majesty's High Court of
Chancery within six calendar months next and immediately after the date of
the said in part recited Letters Patent, as in and by the same, reference being.
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Stocker, do hereby declare the nature of my Invention, and the'

page_text: manner in which the same is to be performed, are runy described and ascer
tained in and by the following statement thereof, reference being had to the
Drawing hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
My Invention consists in a mode of communicating motion to the piston or
bucket of pumps, as will be hereafter particularly described.
DESCRIPTION OF THE DRAWING.
Figure represents a pump, having my improvements applied thereto;
Figure 2 is a section of Figure 1; and Figure 3 shews a section of some of
the parts separately. In each of these Figures the same letters indicate
similar parts.
a, a, is the pump barrel; b, an ordinary bucket or piston; e is
the piston rod attached to the bucket, as is shewn in the Drawing; f is an
arm or lever, moving on an axis at g; this axis passes through to the out-
side of the pump' barrel, and has the handle affixed thereto. And it is
important to remark, that the axis.g, in its passage through to the outside of
the pump barrel is tight, in such manner as to prevent the passage of fluid
through. Figure 3 shews a mode of making a tight stuffing-box to the axis;
but other means may be resorted to. Figures 4 and 5 shew an outside view
and section of another pump, having my improvements applied thereto, the
only difference being that the bucket is applied to a flexible piston of leather
or other suitable material, as will readily be understood on inspecting the
Drawing. In these Figures the same letters of reference indicate similar parts
as before employed. In each of these Figures or arrangements it will be seen
that there is a cover i to the pump, but the piston rod does not pass through
the same; and if it be desired to convert either of the pumps into a force
pump, as well as a lift pump, it will only be necessary to apply a pipe to the
cover, in which case the outlet or spout j should be closed, either by a suitable
plag, or, in place thereof, the outlet should be a cock. The pumps shewn in
the Drawing are particularly intended for the purposes of beer pumps, and
they are so constructed that they unscrew at the part 1, by which the induction
valve may be conveniently got at in the event of its becoming clogged. It
will be evident that like pumps may be used for raising and forcing fluids in
general.
From the foregoing description it will be evident that by making the axis g
fluid-tight, the beer, water, or other fluid may flow above the axis and into
the upper part of the pump, whether for a force pump or a lift pump, without
einploying a cover to the pump with a stuffing-box for the piston rod, to pass
through. And it is the novel arrangement, and mode of applying the handle,

page_text: of pumps which constitutes the claim of novelty under the present Letters
Patent. But I would have it understood that I do not confine my Invention
to the precise arrangement shewn, as variations may be made; nor do I
claim any parts separately or combined other than relates. to the mode of
applying the axis g, and the parts connected therewith, in order to make the
same fluid-tight at the passage of the handle and the axis, as above described.
In witness whereof, I, the said Samuel Stocker, have hereunto set my
hand and seal, this Fourth day of September, in the year of our. Lord.
One thousand eight hundred and thirty-seven.

DISCLAIMER AND MEMORANDUM OF ALTERATION proposed to be
entered by the said Samuel Stocker with the Clerk of the Patents of
England, pursuant to an Act passed in the fifth and sixth year of the
reign of His late Majesty King William the Fourth, entitled "An Act
to amend the Law touching Letters Patent for Inventions."
I, the said SAMUEL STOCKER, since inrolling the said Specification, have
discovered that several years ago a few portable force pumps for gardening
purposes, were made and sold, but which failed and never came into general
use; the upper part of the pump in such case forming an air vessel, the tube
through which the water was forced passing to a considerable extent into the
pump barrel and dipped into the water in the pump barrel, there being no
spout fixed to the pump barrel through which the water could flow into a
vessel below; such an arrangement of force pump required that the parts
where the handle passed through should be air-tight, and resist a considerable
pressure of air from within, which cannot at a reasonable cost be made with
practical utility; and I have been advised, that although the arrangement
described by me did not cause the upper part of the barrel of a force pump to
be converted into an air vessel, but was open to the atmosphere through the
spout; yet that my Specification claims the improvements for combining the
handles fluid tight to pump barrels, with spouts for lift pumps, and also force
pumps. And as the construction of force pumps described in the said Specifi-
cation are not only not new but not useful, the same if allowed to remain part
of the Specification or Invention would destroy my Patent, and the fixed lift
pumps described in my Specification, are highly valuable, for which reasons I
wish to disclaim, and I do hereby disclaim all parts of my said Specification
or Invention which relate to force pumps; and I do wish to confine the claim
to Invention to fixed lift pumps, with spouts similar to j, made according to

page_text: the said Specification. And in order that such Disclaimer may be fully
understood, I have annexed a copy of the Specification, with the parts dis-
claimed ruled through with red ink, the alterations in the title and Specifica-
tion being also in rod inl And in order that the title of the Patent may be
proper for the Invention which will then remain, I have for that reason altered
the title by introducing the words fixed lift before the word pumps.
In witness whereof, I, the said Samuel Stocker, have hereunto set my
hand and seal, this First day of March, One thousand eight hundred
proper for the Invention which will then remain, I have for that reason altered
the title by introducing the words fixed lift before the word pumps.
In witness whereof, I, the said Samuel Stocker, have bereunto set my
hand and seal, this First day of March, One thousand eight hundred
and forty four.
SAM STOCKER. (L.S.)
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
STOCKER; of Bristol, Gentleman, send greeting.
WHEREAS His late most Excellent Majesty King William the Fourth,
by His Letters Patent, under the Great Seal of Great Britain, bearing date
at Westminister, the Fourth day of March, in the seventh year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
Samuel Stocker, His especial licence, full power, sole privilege, and authority,
that I, the said Samuel Stocker, my exors, adñiors, and assigns, or such others
as I, the said Samuel Stocker, my exors, admors, or assigns, should at any
time agree with and no others from time to time and at all times during the
term of years therein expressed, should, and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "IMPROVEMENTS ON FIXED LIFT PUMPS;" in which said Letters
Patent is contained a proviso, that 1, the said Samuel Stocker shall cause a
particular description of the nature of my said Invention, and in what manner
the same is to be performed to be inrolled in His said Majesty's High Court
of Chancery within six calendar months next and immediately after the date
of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Stocker, do hereby declare the nature of my Invention, and the manner
in which the same is to be performed, are fully described and ascertained in
and by the following statement thereof, reference being had to the Drawing
hereunto annexed, and to the figures and letters marked thereon (that is to
say):-
My Invention consists in a mode of communicating motion to the piston or
bucket of pumps, as will be hereafter particularly described.

page_text: Figure 1 represents a fixed lift pump, having my improvements applied
thereto; Figure 2 is a section of Figure 1; and Figure 3 shews a section
of some of the parts separately. In each of these Figures the same letters
indicate similar parts. a, a, is the pump barrel; b, an ordinary bucket or
piston; e is the piston rod attached to the bucket, as is shewn in the Drawing;
f is an arm or lever moving on an axis at g; this axis passes through to the
outside of the pump barrel, and has the handle h affixed thereto; and it is
important to remark, that the axis g, in its passage through to the outside of
the pump barrel, is tight in such manner as to prevent the passage of fluid
through. Figure 3 shews a mode of making a light stuffing-box to the
axis; but other means may be resorted to. Figures 4 and 5 shew an outside
view and section of another pump, having my improvements applied
thereto, the only difference being that the bucket is applied to a flexible
piston of leather or other suitable material, as will readily be understood on
inspecting the Drawing. In these Figures the same letters of reference
indicate similar parts, as before employed. In each of these Figures or
arrangements it will be seen that there is a cover i to the pump, but the piston
rod does not pass through the same; and if it be desired to convert either of the
pumps-into-a-force-pump-as-well-as-a-lift pump, it will only-be-necessary-to-apply-a
pipe-to-the-cover-in-which ease the ; outlet or spout js-hould be closed, either by
a-suitable-plug-or-in-place-thereof the outlet-should-be-a-coek. The pumps shewn
in the Drawing are particularly intended for the purposes of beer pumps, and
they are so constructed that they unscrew at the part 1, by which the induction
valve may be conveniently got at in the event of its becoming clogged. It will
be evident that like pumps may be used for raising and foreing fluids in
general. From the foregoing description it will be evident that by making
the axis g fluid-tight, the beer, water or other fluid may flow above the
axis and into the upper part of the pump, whether-for-a-foree-pump-or a lift
pump, without employing a cover to the pump, with a stuffing-box for
the piston rod to pass through. And it is the novel arrangement, and mode
of applying the handle; of fixed lift pumps having spouts which constitutes
the claim of novelty under the present Letters Patent. But I would have it
understood that I do not confine my Invention to the precise arrangement
shewn, as variations may be made; nor do I claim any parts separately or com-
bined other than relates to the mode of applying the axis g, and the parts
connected therewith, in order to- make the same fluid-tight at the passage of

To the Clerk of the Patents for England.
This is to certify that the above-named Samuel Stocker, of Bristol, Gentle-
man, has applied to me for leave to enter with you the above written
Disclaimer & Memorandum of Alteration of part of the title & Specification
of a certain Invention, for which Letters Patent were granted to him under
the Great Seal of Great Britain, dated at Westminster, the 4th day of March
1837, and to which a Specification was duly enrolled, and on considering the
said application, I directed him to advertise his said Disclaimer & Memoran-
dum of Alteration, and such advertisements having been duly made, namely,
in the Times & Morning Chronicle newspapers on the 14th of February last,
in the Morning Herald on the 15th, and in the London Gazette on the 16th
of the same month, and no objection having been made to the same, I have
accordingly granted leave to the said Samuel Stocker to file his said Dis-
claimer & Memorandum of Alteration pursuant to the Statute passed in the
fifth & sixth years of the reign of His late Majesty King William the
Fourth, entituled, An Act to amend the Law touching Letters Patent for
