IMPROVED MEANS FOR PRODUCING AND SUSTAINING PRESSURE APPLICABLE TO THE RAISING AND THE TRANSFERENCE OF LOADS
Year: 1874

page_text: LETTERS PATENT to William Anderson, of Southwark Street, in the
Borough of Southwark, Engineer, for the Invention of "IMPROVED
MEANS FOR PRODUCING AND SUSTAINING PRESSURE APPLICABLE TO THE RAISING
AND THE TRANSFERENCE OF LOADS."
PROVISIONAL SPECIFICATION left by the said William Anderson at
the Office of the Commissioners of Patents, with his Petition, on
the 31st December 1874.
I, WILLIAM ANDERSON, of Southwark Street, in the Borough of
Southwark, Engineer, do hereby declare the nature of the said Inven-
tion for "IMPROVED MEANS FOR PRODUCING AND SUSTAINING PRESSURE APPLI-
CABLE TO THE RAIsing and the Transference of Loads," to be as follows :—
The object of this Invention is to avoid the necessity at present
experienced for using accumulators in connection with lifting machinery,
such as that adapted for short lifts of heavy loads, and for working heavy
guns and ships' turrets. The use of an accumulator not only adds to the

page_text: expense of the lifting machinery but offers a great obstacle to the intro-
duction of such machinery on board ship, and indeed wherever spaco is
very limited.
versa.
As a substitute for the costly mechanism now used for the above
named and kindred purposes I propose to employ as my source of power
the arrangement of pumping engine, patented by W. E. Newton on the
28th January 1862, No. 226, the peculiarity of which is that the piston
rods of the steam cylinders serve also as the pump rods, and that the rod
of one cylinder will work the valve of the adjacent cylinder, and vice
This arrangement admits of the pump being started and stopped
by simply opening or closing the steam supply pipe. If now this
pumping engine is connected with a piston or plunger of an hydraulic
apparatus adapted, say, for lifting a heavy gun into position, or applied
to a turbine, the rotation of which will, through screw or equivalent
gearing, work a turret, a capstan, or a crane; the boiler which supplics
steam to the motive-power engine will be made to act the part of the
water or air accumulator of the Armstrong and other lifting apparatus
at present employed in docks and factories for raising, sustaining, and
transforring heavy loads, and thus thereby a greatly extended appli-
cation of hydraulic lifting apparatus will result.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Anderson in the Great Scal Patent Office
on the 30th Juno 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ANDERSON, of Southwark Street, in the Borough of Southwark, Engineer, a
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of December, in tho
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Anderson, Her special licence
that I, tho said William Anderson, my executors, administrators, and
assigns, or such others as I, the said William Anderson, my executors,
administrators; and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during tho term

page_text: 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 "IMPROVED MEANS
FOR PRODUCING AND SUSTAINING PRESSURE APPLICABLE TO THE RAISING AND
THE TRANSFERENCE OF LOADS," upon the condition (amongst others) that
I, the said William Anderson, my exccutors or administrators, by an
instrument in writing under my, or their, or one of their hands and
scals, should particularly describo 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 Scal 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 Anderson, do hereby declare
the nature of my said Invention, and in what manner the same is to be
3 performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto
annexed and to the letters and figures marked thercon (that is to
say) :-
The object of this Invention is to avoid the necessity at present
O experienced for using accumulators in connection with lifting machinery
such as that adapted for short lifts of heavy loads, and for working heavy
and ships' turrets. The use of an accumulator not only adds to
the expense of the lifting machinery but offers a great obstacle to the
introduction of such machinery on board ship, and indeed wherever

As a substitute for the costly mechanism now used for the abovo
named and kindred purposes I propose to employ as my source of power
a slightly modified form of the arrangement of pumping engine, patented
by William Edward Newton on the Twenty-eighth January, One thou:
O sand eight hundred and sixty-two, No. 226, the peculiarity of which is
that the piston rods of the steam cylinder serve also as the pump rods, and
that the rod of one cylinder will work the valve of the adjacent cylinder,
and vice versa. This arrangement admits of the pump being started and
stopped by simply opening or closing the delivery pipe from the pump.
5 If now this pumping engine is connected with a piston or plunger of an
hydraulic apparatus adapted, say, for lifting a heavy gun into position
or applied to a water engine, the rotation of which will, through screw

page_text: The pipe G is provided with two valves L, M, the former of which
supplies the fluid under pressure from the force pumps to the cylinder H,
and the latter when opened provides for the discharge of the fluid from
that cylinder. From this example it will be obvious that the raising and
lowering of the platform will be perfectly under the command of the
attendant, the opening of the valve L to admit fluid from the force
pump to the cylinder H causing (by the discharge of fluid from the
pump) the boiler to supply more steam to the engine cylinder with
which it is in connection, and the shutting of that valve checking the
further supply of steam to the engine by stopping the discharge of the
fluid from the pump. The quick answering of the engine to the require-
ments of the work, and also the efficient sustaining of the load, is ensured
by the jacketing of the steam cylinders, as condensation of steam in the
cylinders is thereby prevented, and special attention to the engine is
rendered unnecessary.
Having now set forth the nature of my Invention of "Improved
Means for Producing and Sustaining Pressure Applicable to the Raising
and the Transference of Loads," and explained the manner of carrying
the same into effect, I wish it to be understood that under the above in
part recited Letters Patent I claim the arrangement above described,
whereby the attendant on the lifting apparatus is enabled to apply the
power stored in steam boilers for producing and sustaining the pressure
required to be exerted in or by such apparatus.
In witness whereof, I, the said William Anderson, have hereunto
set my hand and seal, the Thirtieth day of June, in the year of
our Lord One thousand eight hundred and seventy-five.
