IMPROVEMENTS IN PORTABLE CENTRIFUGAL PUMPS
Year: 1864

page_text: LETTERS PATENT to Charles Thomas Burgess, of Brentwood, in the
County of Essex, for the Invention of "IMPROVEMENTS IN PORTABLE
CENTRIFUGAL PUMPS."
Sealed the 13th April 1865, and dated the 7th November 1864.
PROVISIONAL SPECIFICATION left by the said Charles Thomas Burgess
at the Office of the Commissioners of Patents, with his Petition, on the
7th November 1864.
I, CHARLES THOMAS BURGESS, of Brentwood, in the County of Essex, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN PORTABLE
CENTRIFUGAL PUMPS," to be as follows:-
This Invention has for its object improvements in centrifugal pumps. In
arranging portable centrifugal pumps, where the pump is mounted on a
wheeled carriage for ready transport from place to place, the suction pipe is
now commonly jointed or made to swivel at a point immediately below the
body of the pump. This jointed suction pipe is, however, found very incon-
venient, and it renders it necessary to carry the pump at a considerable
distance above the land, and this when the water is required to be raised only
to the surface of the land, as is usually the case, involves a considerable loss
of power.
Now according to my Invention, I so arrange the pump that a rigid suction

page_text: pipe may be conveniently used. The required inclination of the suction pipe
to suit the distance of the water below the pump being obtained by the move-
ment of the disc or wheel case, together with the suction pipe, in place of by
the turning of the suction pipe separately on its joint or swivel.
The following is the arrangement I prefer :-The frame on which the pump
is fixed is furnished with stud axes on each side to receive the carrying
wheels. These stud axes are in line with the axis of the disc or wheel which
is between them, and they receive the shafts by which the pump is connected
with the portable engine employed in driving it. The pump frame, with the
pump and suction pipe, are thus all able to turn together about the axes of
the carrying wheels, and it is thus that the required inclination of the suction
pipe is obtained. It will be seen that in this arrangement the length of
driving belt required will not vary whatever be the position of the suction
pipe.
It is not essential, although it is convenient, that the axis of the disc, the
centre about which the pump pivots, and the points of attachment of the
shafts should be all in the same line so long as the suction pipe be made rigid
with the pump case, and the two moved together in adjusting the inclination
of the suction pipe.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Thomas Burgess in the Great Seal Patent Office on
the 2nd May 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
THOMAS, BURGESS, of Brentwood, in the County of Essex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of November, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Charles Thomas Burgess, Her special licence that I, the said Charles
Thomas Burgess, my executors, administrators, and assigns, or such others as
I, the said Charles Thomas Burgess, 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 PORTABLE CENTRIFUGAL PUMPS," upon the condition (amongst

page_text: others) that I, the said Charles Thomas Burgess, my executors or adminis-
trators, 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 Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Charles Thomas Burgess, 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 :-
This Invention has for its object improvements in portable centrifugal
pumps. In arranging portable centrifugal pumps, where the pump is
mounted on a wheeled carriage for ready transport from place to place, the
suction pipe is now commonly jointed or made to swivel at a point imme-
diately below the body of the pump. This jointed suction pipe is, however,
found very inconvenient, and it renders it necessary to carry the pump at a
considerable distance above the land, and this when the water is required to
be raised only to the surface of the land, as is usually the case, involves a
considerable loss of power.
Now according to my Invention I so arrange the pump that a rigid suction
pipe may be conveniently used. The required inclination of the suction pipe
to suit the distance of the water below the pump being obtained by the move-
ment of the disc or wheel case, together with the suction pipe, in place of by
the turning of the suction pipe separately on its joint or swivel.
The following is the arrangement I prefer :-The frame on which the
pump is fixed is furnished with stud axes on each side to receive the carrying
wheels. These stud axes are in line with the axis of the disc or wheel which
is between them, and they receive the shafts by which the pump is connected
with the portable engine employed in driving it. The pump frame, with the
pump and suction pipe, are thus all able to turn together about the axes of
the carrying wheels, and it is thus that the required inclination of the suction
pipe is obtained. It will be seen that in this arrangement the length of
driving belt required will not vary whatever be the position of the suction
pipe.
It is not essential, although it is convenient, that the axis of the disc, the
centre about which the pump pivots and the points of attachment of the shafts
should be all in the same line so long as the suction pipe be made rigid with
the pump case, and the two moved together in adjusting the inclination of
the suction pipe.

page_text: And in order that my Invention may be more fully understood, and readily
carried into effect, I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.

a is a centrifugal pump, the axis of which is carried by the frame b. The
'frame 6 is furnished with stud axes c, c, on which the carrying wheels d, d,
are mounted and turn. By the arrangement it will be seen that the rotatory
pump, with its frame b, is capable of turning about the centres of the
carrying wheels d, d, and any inclination of the suction pipe may be thus
obtained. is a driving drum on the axis of the pump, on which a band
from a portable engine passes. The axis of the pump is in a line with the
stud axes c, c, by which means the length of driving belt or strap
same whatever be the position of the suction pipe or inlet f. The water
raised by the rotatory pump is driven out through the pipe outlet g.
Figure 8, the rotatory pump, with its frame, is shown by red lines to be
turned into another position to that indicated by the black lines. h is a
quadrant firmly attached to the frame b, and having a number of holes in it,
through one of which and a lugi on the shafts a pin is passed, by which the
pump is retained in the desired position, and its frame held at the required
inclination, or this may be accomplished in any convenient manner.
In
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that what I claim is, tho
mode herein described of mounting portable centrifugal pumps, so that their
suction pipes may be made to assume different positions to suit the different
positions of the water in respect to the pump.
In witness whereof, I, the said Charles Thomas Burgess, have hereunto
set my hand and seal, this Twelfth day of February, in the year of our
Lord One thousand eight hundred and sixty-five.
