Year: 1866

page_text: LETTERS PATENT to Edward Taylor Bellhouse and William Jobn
Dorning, both of Manchester, in the County of Lancaster, Engineers,
for the Invention of "CERTAIN IMPROVEMENTS IN HYDRAULIC PUMPS, AND IN
VALVES CONNECTED THEREWITH, AND ALSO IN THE METHOD OF DRIVING OR
ACTUATING SUCH PUMPS."
Sealed the 30th November 1866, and dated the 31st May 1866.
PROVISIONAL SPECIFICATION left by the said Edward Taylor Bellhouse
and William John Dorning at the Office of the Commissioners of Patents,
with their Petition, on the 31st May 1866.
We, EDWARD TAYLOR BELLHOUSE and WILLIAM JOHN DORNING, both of
Manchester, in the County of Lancaster, Engineers, do hereby declare the
nature of the said Invention for "Cr:TAIN IMPROVEMENT IN HYDRAULIC PUMPS,
AND IN VALVES CONNECTED THEREWITH, AND ALSO IN THE METHOD OF DRIVING OR
ACTUATING SUCH PUMPS," to be as follows:-
Our Invention relates, first, to a novel and peculiar arrangement and
disposition of the pumps employed in hydraulic engines, whereby the removal,
cleansing, and fixing of the suction pipes of such pumps are rendered simple
and more convenient than hitherto; and, secondly, the Invention relates to a

page_text: peculiar arrangement and disposition of valves employed to prevent a further
supply of water to hydraulic presses from the pumps so soon as a certain
pressure is obtained, to which the valve may be regulated and weighted.
The improvements consist, first, in raising the pumps above the cistern lid
or cover, and supporting them upon suitable bearings in such a position that
the lower flange of the pump forming the connection with the suction pipe
shall be about level or on a line with the cistern cover, so that the screw
connecting the pump with the suction pipe may be easily turned without
removing any part of the cistern.
Secondly, the improvements consist in the application and use of an air
valve attached to the feed pipe between the pumps and the ordinary valve,
such air valve consisting of a cylinder having an opening for the admission of
air, which is provided with a hinged lid or covering forming a perfect joint,
closing the opening, and being firmly retained upon its seating until the
pressure of water is equal to the pressure wherewith the ordinary valve is
weighted, at which time the covering is raised from the orifice in the feed
pipe, allowing the admission of air, and by thus causing the pumps to draw in
air acts as a safety valve, and prevents a further supply of water from tho
pumps.
.
In another arrangement of the pumps we place or dispose them in pairs on
each side of the cistern, instead of all in a direct line in the centre of the
cistern, as at present. By this means the suction pipes and connections may
be outside the cistern, entering it at the bottom, the pumps being bolted or
secured to the sides of the cistern.
Lastly, our Invention is designed for the purpose of supporting the large
toothed driving wheel used to drive hydraulic pumps, so as to prevent the
friction of the shaft from wearing the hole in the boss of the wheel unevenly.
This part of the improvements consists in the use of a pair of blocks mounted
in a framing, and actuated by right and left handed screws in such a manner
that when the "clutch box" is out of gear and the toothed wheel thereby
disconnected from the constantly revolving driving shaft the blocks may be
screwed up beneath the said wheel, and act as a support thereto to prevent
its weight bearing on the shaft, and consequently removing the friction and
preventing the wearing of the surface.

by the said Edward Taylor Bellhouse and William John Dorning in the
Great Seal Patent Office on the 30th November 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
TAYLOR BELLITOUSE and WILLIAM JOHN DORNING, both of Manchester, in the
County of Lancaster, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of May, in the year of our Lord One
thousand eight hundred and sixty-six, in the twenty-ninth year of Her reign,
did, for Herself, Her heirs and successors, givo and grant unto us, the said
Edward Taylor Bellhouse and William John Dorning, Her special licenso
that we, the said Edward Taylor Bellhouse and William John Dorning,
our executors, administrators, and assigns, or such others as we, the said
Edward Taylor Bellhouse and William John Dorning, our 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 IMPROVEMENTS IN HYDRAULIC PUMPS,
AND VALVES CONNECTED THEREWITH, AND ALSO IN THE METHOD OF DRIVING AND
ACTUATING SUCH PUMPS," upon the condition (amongst others) that we, the
said Edward Taylor Bellhouse and William John Dorning, our executors or
administrators, by an instrument in writing under our, 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 we, tho said Edward Taylor Bellhouse and
William John Dorning, 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 and accompanying Drawings
(that is to say):—
Our Invention relates, first, to a novel and peculiar arrangement and
disposition of the pumps employed in hydraulic engines, whereby the removal,
cleausing, and fixing of the suction pipes of such pumps is rendered simple

page_text: and more convenient than hitherto; and, secondly, the Invention relates to a
peculiar arrangement and disposition of valves employed to prevent a further
supply of water to bydraulic presses from the pumps as soon as a certain
pressure is obtained, to which the valve may be regulated and weighted.
The improvements consist, first, in raising the pumps above the cistern lid
or cover, and supporting them upon suitable bearings in such a position that
the lower flange of the pump forming the connection with the suction pipe
shall be about level or on a line with or above the cistern cover, so that the
screw connecting the pump with the suction pipe may be easily turned
without removing any part of the cistern, which object may be attained by
different arrangements, as illustrated in the Drawings attached.
Secondly, the improvements consist in the application and use of an air
valve attached to the feed pipe between the pumps and the ordinary valve,
such air valve consisting of a cylinder having an opening for the admission of
air, which is provided with a hinged lid or covering, forming a perfect joint,
closing the opening, and being firmly retained upon its seating until the
pressure of water is equal to the pressure wherewith the ordinary valve is
weighted, at which time the covering is raised from the orifice in the feed
pipe, allowing the admission of air, and by thus causing the pumps to draw in
air acts as a safety valve, and prevents a further supply of water from the
pumps.
In another arrangement of the pumps we place or dispose them in pairs on
each side of the cistern, instead of all in direct line in the centre of the
cistern, as at present. By this means the suction pipes and connections may
be outside the cistern, entering it at the bottom, the pumps being bolted or
secured to the sides of the cistern.
Lastly, our Invention is designed for the purpose of supporting the large
toothed driving wheel used to drive bydraulic pumps so as to prevent the
friction of the shaft from wearing the hole in the boss of the wheel unevenly.
This part of the improvements consist in the use of a pair of blocks mounted
in a framing, and actuated by right and left handed screws in such a manner
that when the "clutch box" is out of gear and the toothed wheel thereby
disconnected from the constantly revolving driving shaft the block may be
screwed up beneath the said wheel and act as a support thereto to prevent its
weight bearing on the shaft, and consequently removing the friction and
preventing the wearing of the surface.
In order that the Invention may be better understood and explained in
detail we have hereunto attached two Sheets of Drawings made upon a scale

page_text: of about one inch and a half to the foot, similar letters of reference being
marked upon corresponding parts of the apparatus.
In Sheet 1, Fig. 1 represents an end elevation of the apparatus connected
with hydraulic pumps, the cistern and brackets supporting the pumps being
shewn in section; Fig. 2 represents a side elevation of the same, the pumps
being arranged about half way between the entablatures in the ordinary
manner; and Fig. represents an end elevation of the improved arrangement
of the pumps which are arranged along the sides of the cistern, thereby
rendering the operations of cleaning, alterations, or repairs more convenient.
In Sheet 2, Fig. 1 represents a novel arrangement of bracket or supports
to be employed for supporting the toothed driving wheel in order to take the
weight of the same off the continuously revolving driving shaft when the
clutch box is not in gear and such wheel is not revolving, whereby the friction
and wearing of the shaft and wheel boss is prevented when not required for
driving; and Fig. 2 represents a sectional elevation of the friction cone and
driving wheel; and Fig. 3 a half elevation of the same; these views illustrate
the method and arrangement adapted for readily placing and adjusting the
driving wheel upon the driving shaft, and for inserting a "bush" in the boss
of the wheel to make a proper fitting between the shaft and wheel without
disarranging any other portion of the machine or removing the shaft from its
bearings; this wheel may be either used alone or in conjunction with the
supporting blocks.
In Sheet 1 and Figs. 1, 2, and 3, are the intablatures or supports ;
b, b, the pumps; c, the cistern; and d, the suction pipes, all being well-known
parts of the bydraulic apparatus. The different dispositions and arrangements
of pumps (as shewn in Figs. 1 and 3) are supplied with the same apparatus,
therefore the letters of reference applying to one will be similar on the other.
The bracket or platform e supporting the pump 6 are provided to raise tho
pumps above the top of the cistern c, in order that the screws connecting the
pumps with the suction pipes d, d, may be readily turned or attended to
without removing any part of the cistern cover, the suction or feed pipes &
being readily withdrawn from or inserted in the cistern through the slot or
opening formed in the lid or cover for the purpose. The said slot and
elevating platform are not necessary, and are dispensed with when the pumps
are disposed and arranged in couples, as seen in Fig. 3. The delivery pipe of
each pump is provided with a valve h, which is supported on the bracket ŷ,
and weighted by means of the levers k and weight i, so as to offer a given
resistance to the pressure of water actuating the press. The pipe / projecting

page_text: from the suction pipe d is provided with an air valve m, which consists of a
small cylinder having an aperture for the admission of air, which is covered
by a hinged lid o, which is firmly retained upon its seating by means of the
weighted lever k, to which it is connected by the levers and rod p as long as
the pressure of water is below the resistance of the valve , but when the
pressure is attained the lever k is lifted by the valve h, and through the
medium of the levers and rod p the hinged lid o is raised, thereby admitting
air, which prevents the proper suction of the pumps causing them to draw in
air, and then acts as a safety valve, and prevents undue pressure and straining
of the apparatus.
In Sheet 2, Fig. 1, a, a, are a pair of blocks mounted in bearings secured
to or forming part of the framing b; these blocks are actuated by the right
and left handed screws c, c, in such a manner that when the friction cone is
out of gear and the toothed driving wheel d disconnected from the constantly
revolving driving shaft e the blocks a, a, are screwed up beneath the said
wheel, and act as supports thereto, preventing the weight of the wheel
bearing upon the shaft, consequently removing the friction, and preventing
the wearing of the surfaces. This driving wheel is shewn in Figs. 2 and 3
made or cast in halves or segments which are secured together by the
bolts ff; by this means it is readily taken off or put upon the driving shaft
for repairs, or when the hole has become too large by wearing a "bush" may
be inserted in the "boss" of the wheel, and bored out to fit the shaft without
disarranging any other portion of the apparatus. The collar or ring 9 being
placed against the boss of the wheel, and firmly secured to the shaft, thereby
keeping such wheel in its proper position for driving.
Having now described the nature of the said Invention, together with the
.method of carrying the same into practical effect, we wish it to be distinctly
understood that we claim,-
First, arranging and constructing hydraulic pumps, their cisterns, and other
apparatus in such a manner that the suction pipes may be removed and
replaced without removing the cistern cover, or unnecessarily disturbing other
parts of the apparatus.
Secondly, wo claim the adaptation and application of an air valve to admit
air to the pumps instead of water after a given pressure is attained.
Thirdly, we claim the employment and use of a support or supports for the
large toothed driving wheel of hydraulic pumps to receive and sustain the
weight thereof when not revolving.
And, lastly, we claim the general arrangement, construction, and com-

page_text: bination of the apparatus herein-before described, set forth, and fully
illustrated in Drawings attached.
In witness whereof, we, the said Edward Taylor Bellhouse and William
John Dorning, have hereunto set our hands and seals, this Twenty-
eighth day of November, in the year of our Lord One thousand eight
hundred and sixty-six.
