CERTAIN IMPROVEMENTS. IN PUMPS
Year: 1853

page_text: LETTERS PATENT to John Rumley, of South Shields, in the County
of Durham, for the Invention of "CERTAIN IMPROVEMENTS. IN
PUMPS."
Sealed the 8th July 1853, and dated the 13th January 1858.
PROVISIONAL SPECIFICATION left by the said John Rumley at
the Office of the Commissioners of Patents, with his Petition, on
the 13th January 1853.
JOHN RUMLEY, do hereby declare the nature of the said Invention
for "CERTAIN IMPROVEMENTS IN PUMPS" to be as follows:-
The nature of this Invention consists in the use and application to
ships' and other pumps of parallel motion in combination with a crank
for the purpose of imparting motion to the buckets, plungers, or pistons
of said pumps; and a peculiar feature in this Invention consists in placing
within a pump barrel two buckets, and imparting motion thereto simul-
taneously in opposite directions, so as to cause onc of the said buckets,
plungers, or pistons to ascend whilst the other is descending, thereby
effecting and maintaining a continuous flow of water or other liquid,
instead of the intermittent flow consequent in using single pumps as
hitherto constructed, and in which only one bucket, plunger, or piston is
employed.

page_text: In the accompanying Drawing Fig. 1, is a transverse and vertical
section of a pump, shewing the crank A, at its greatest height, as also
the relative positions of the several parts in connection therewith; and
Fig. 2, exhibits the crank A, at its lowest point, as also the relative
position of the several parts in connection therewith. In both of these
Figures similar letters of reference are employed to denote correspond-
ing parts. B, B, nark rods in connection with the bucket, plunger,
or piston C; and D', D, rods in connection with the bucket, plunger, or
piston E; F, F, guide links or rods for effecting the parallel vertical
movement of the rods G, and H. By this arrangement it will appear
manifest that as the crank A, rotates, the rods B, B, and D, D, will be
moved in opposite directions, and thereby effect the raising of one
bucket and the descent of the other, so that one or other of the said
buckets, plungers, or pistons will be continuously lifting water or other
liquid so long as the crank A, is in motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Rumley in the Great Seal Patent Office
on the 13th July 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1,
JOHN RUMLEY, of South Shields, in the County of Durham, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of January, in the year
of our Lord One thousand eight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Rumley, Her special licence
that I, the said John Rumley, my executors, administrators, and
assigns, or such others as I, the said John Rumiley, 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 "CERTAIN IMPROVE-

page_text: MENTS IN PUMPS," upon the condition (amongst others) that I, the
said John Rumley, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the saïd
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 I, the said John Rumley, 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 (that is to say):
The nature of my said Invention consists in the use and application
to ships' and other pumps of certain mechanism in combination with a
crank or eccentric, or cranks or eccentrics, for the purpose of impart-
ing motion to the buckets, plungers, or pistons, or what are technically
termed spear boxes, of said pumps; and a peculiar feature in my said
Invention consists in imparting motion simultaneously to said spear
boxes in opposite directions, so as to cause one of the said spear boxes
to ascend whilst the other is descending, by which I am enabled
effect and maintain a continuous flow of water or other liquid in pumps,
instead of the intermittent flow consequent in using pumps as hitherto
constructed.
And in order to explain my said Invention as completely as possible
I will proceed to describe the mechanical arrangements and combina²-
tions which I have found to answer well in practice, reference being
had to the illustrative Drawing hereunto annexed, and to the numeral
figures and letters of reference marked thereon respectively as follows:
DESCRIPTION OF THE DRAWING.
"
Figure 1, exhibits a transverse and vertical section of a pump con-
structed according to my said Invention, shewing the crank A, at its
greatest height, as also the relative positions of the several parts in con-
nection therewith. Figure 2, exhibits the crank A, at its lowest point,
as also the relative positions of the several parts in connection there-
with. Figure 3, is a transverse and vertical section of two double

page_text: .
.acting pumps, in which the plungers or buckets thereof are connected
together and actuated by levers in combination with a crank or cranks
or an eccentric or eccentrics, fixed to or formed upon the main shaft in
a somewhat similar manner and upon the same principle of construction
to that before described and represented at Figures 1, and 2. Figure
3, exhibits the position of the mechanism as it would appear when the
buckets are receding from each other; and Figure 4, shews the position
of the mechanism when the buckets are approaching each other. At
.each of these Figures similar letters of reference are placed upon and
denote corresponding parts, in so far as such parts appear or can be
seen at each of the Figures respectively. B, B, mark rods in connec-
tion with the spear box; bucket, plunger, or piston C; and D, D, are
rods in connection with the spear box, bucket, plunger, or piston E.
F, F, are guide links or rods for effecting the parallel vertical move-
.ment of the rods G, and H. By this arrangement it will appear
manifest that as the crank A, rotates, the rods B, B, and D, D, will be
moved in opposite directions, and thereby effect the raising of one spear
box and the descent of the other, so that one or other of the said spear
boxes will be continuously lifting water or other liquid so long as the
crank A, is in motion. With reference to Figures 3, and 4, the me-
chanical arrangements there shewn differ from those before described
and represented at Figures 1, and 2, in the following respects: the
mechanism employed for imparting motion to the spear boxes or buckets
C, and E, instead of being placed immediately over the pump barrel,
as at Figures 1, and 2, is placed between the two pump barrels, and the
said spear boxes or buckets are connected thereto by cross heads I, and
K; the cross head I, is connected to each of the lower spear boxes or
buckets C, C, by a rod L, which passes and works, water-tight, through
the upper spear boxes or buckets E, E; these last-mentioned spear
boxes are connected to the cross head K, which cross head is connected
to the lazy tongs levers D, D, as shewn, and the vertical movement
thereof and of the spear boxes or buckets C, C, is effected by a rod M,
which works through guide holes formed in the cross pieces N, affixed
to the pump barrels. The upper cross head I, is connected to the crank
or eccentric A, on the. main driving shaft by a rod O, to which is also

page_text: connected the upper lazy tongs levers B, B. By this arrangement it
will be seen that the rotation of the shaft and crank or eccentric A,
thereon, will impart up and down movement to the cross head I, and
spear boxes or buckets C, C, connected therewith, and the lazy tongs
levers D, D, and rods F, F, will effect the up and down movement of
the spear boxes E, E.
Having now described the nature of my said Invention, and in what
manner the same is to be and may be performed, I ilesire it to be dis-
tinctly understood that I do not claim the exclusive use of any of the
separate parts above mentioned and referred to; neither do I claim the
use of two spear boxes, plungers, or buckets, except in so far as the
same may be employed in combination and for the purposes of my
said Invention, which I hereby declare to consist in, and claim as of
my Invention of "Certain Improvements in Pumps," the combining
of the spear boxes of pumps with the above-mentioned mechanical
arrangements in the manner herein-before particularly described, set
forth, and represented by the illustrative Drawing hereunto annexed.
for the purpose of effecting and maintaining a continuous flow of water
therefrom.
In witness whereof, 1, the said John Rumley, have hereunto set
my hand and seal, this Eleventh day of July, in the year of
our Lord One thousand eight hundred and fifty-three.
Witness,
JOHN RUMLEY. (L.S.)
