FOR RAISING AND FORCING FLUIDS AND LIQUIDS.”
PROVISIONAL SPECIFICATION left by the said William Allen at the
Office of the Commissioners of Patents, with his Petition, on the
23rd January 1875.
=
I, WILLIAM ALLEN, of Manchester, in the County of Lancaster,
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR RAISING AND FORCING FLUIDS AND LIQUIDS,"
to be as follows:-
My Invention consists in an improved combination and arrangement
of the parts forming a double acting pump, whereby the construction is
simplified and the parts are more casily adjusted and repaired than those
made in the ordinary manner.
The
pump consists of a plunger which works in a cylinder, the upper
part of which is closed by a gland with a double seating; one seating is

page_text: to tighten up the packing through which the plunger works, and the
other seating acts on the packing that prevents the escape of the fluid or
liquid through the gland. The ingress and egress valves are connected
by side passages to the upper and lower ends of the cylinder, and the
upper passage passes through the gland between the two seatings. The
hole in the gland must be wider than the passage to allow for the
tightening up of the gland. The rod of the plunger is connected as
usual to the piston rod of an inverted steam cylinder by which the
power is obtained for working the plunger to and fro in the pumping
cylinder, or the power may be communicated in any other convenient
. manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Allen in the Great Scal Patent Office
on the 21st July 1875.
:
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ALLEN, of Manchester, in the County of Lancaster, Engineer, send
grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of January, in the
year of our Lord One thousand cight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Allen, Her special
license that I; the said William Allen, my executors, administrators, and
assigns, or such others as I, the said William. Allen, 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 "IMPROVEMENTS
IN MACHINERY FOR RAISING AND FORCING FLUIDS AND LIQUIDS," upon the con-
dition (amongst others) that I, the said William Allen, 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 Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal

page_text: Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Allen, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
My Invention consists in an improved combination and arrangement
of the parts forming a double acting pump, whereby the construction is
simplified and the parts are more easily adjusted and repaired than those
`made in the ordinary manner.
r
The pump consists of a plunger which works in a cylinder, the upper
part of which is closed by a gland with a double seating; one seating is
to tighten up the packing through which the plunger works, and the
other seating acts on the packing that prevents the escape of the fluid or
5 liquid through the gland. The ingress and egress valves are connected
by side passages to the upper and lower ends of the cylinder, and the
upper passage passes through the gland between the two seatings. The
hole in the gland must be wider than the passage to allow for the
tightening up of the gland. The rod of the plunger is connected as
usual to the piston rod of an inverted steam cylinder. by which the
power is obtained for working the plunger to and fro in the pumping
cylinder, or the power may be communicated in any other convenient
manner.
And in order that my Invention may be fully understood and readily
, carried into operation I will proceed to describe the accompanying Sheet
of Drawings.
a is an inverted steam cylinder, the piston rod of which is connected
to the open frame b, in which the crank shaft crevolves; to the frame 6
is-keyed the rod d, which is secured to the plunger e; these parts and
the ingress valves f, f¹, egress valves 9, 9¹, and the columns in which
they are. placed are made in the usual manner. The plunger works
partly in the cylinder h and partly in the gland i, which is provided with
a double seating. The lower seating is to tighten up the packing
through which the plunger works, and the other seating is for the gland
which forms the joint between the gland i and the upper part of the
cylinder h. The ingress valves. f, f¹, and the egress valves 9, 9', in the
side columns are connected by the side passages k, k', to the lower end

page_text: of the cylinder h and the upper portion of the gland i, which answers
the purpose of the cylinder. The passages k, k¹, are cast with the side
columns, and the cylinder and the upper passage k coincides with a hole
in the gland i, which hole is placed between the seatings of the glands
i and j, and must be wider than the passage k to allow for the tightening
up of the gland i.
The mode of operation is as follows, and the Drawing shews the parts
in the positions they occupy when the plunger e is ascending; the ingress
port is then open, and the fluid or liquid to be pumped is passing.
through the passage ¹ into the cylinder 7, while the fluid or liquid from
the gland which forms. the upper part of the cylinder is escaping
through the passage / and egress valve g.. When the plunger descends
the valves and are instantly closed, and the valves f and are
opened as in ordinary double acting force pumps. By means of these
improvements, the construction is simplified and the parts are easy of
access for repairs.
Having thus stated the nature of my Invention and described the
manner of performing the same, I declare that I claim the double gland
marked forming the upper part of the cylinder and the passage.
through it for the admission and emission of the fluid or liquid to be
pumped.
In witness whereof, I, the said William Allen, have hereto set my
hand and cool this Twentieth day of July One thousand sight
