Year: 1857

page_text: LETTERS PATENT to Julius Roberts, of St. Leonard's Iron Works, Poplar,
in the County of Middlesex, Captain in the Royal Marine Artillery, and
Miles Beale, of Surrey Street, Strand, in the City of Westminster, Navy
Agent, for the Invention of "IMPROVED MACHINERY FOR OBTAINING AND
APPLYING MOTIVE POWER, APPLICABLE CHIEFLY TO THE WORKING OF SHIPS'
PUMPS, AND OTHER MECHANISM ON SHIPBOARD."
PROVISIONAL SPECIFICATION left by the said Julius Roberts and
Miles Beale at the Office of the Commissioners of Patents, with their
Petition, on the 11th December 1857.
We, JULIUS ROBERTS, of St. Leonard's Iron Works, Poplar, in the County
of Middlesex, Captain in the Royal Marine Artillery, and MILES BEALE, of
Surrey Street, Strand, in the City of Westminster, Navy Agent, do hereby
declare the nature of the said Invention for "IMPROVED MACHINERY FOR
OBTAINING AND APPLYING MOTIVE POWER, APPLICABLE CHIEPLY TO THE WORKING
OP SHIPS PUMPS, AND OTHER MECHANISM ON SHIPBOARD," to be as follows:-
This Invention relates to the application of a weighted rod which is capable
of receiving a vibrating or a rotary motion to the driving of machinery. We
propose chiefly to apply our Invention to the actuating of ships' pumps,
capstans, and other uses on shipboard, as we are then enabled to avail
ourselves of the rolling motion of the vessel for setting the weighted rod in
motion.

page_text: When adapting the Invention in the simplest form to produce a re-
ciprocating motion suitable for working a pair of pump pistons, we suspend a
pendulum rod carrying any given weight from the rock shaft of a cross beam,
and connect the opposite ends of this beam by means of pendent rods to the
pistons of the pump cylinders. As, therefore, the vessel rolls the pendulum
will be caused to oscillate (it being guided in its course by antifriction rollers
running upon guide rails) and set in motion the cross beam, the vibrating
action of which will raise and depress the pistons alternately; or instead of
attaching the pendulum directly to the rock shaft it may have a separato
centro of motion and drive the beam through the medium of sector racks.
For obtaining a rotary action from the vibrating pendulum, we propose
to continue the pendulum rod beyond its centre of motion, and to connect it
to a rocking lever by gearing or otherwise. To the opposite arms of this
lover we attach pawls which take into the teeth of a ratchet wheel, and by
their alternate action impart a continuous rotary motion to the shaft of that
wheel, which notion may be communicated directly or by gearing to a capstan
or windlass barrel, or other mechanism required to be driven.
When we desire that the weighted rod shall receive and impart a rotary
motion, we mount it in gimbals or suspend it in a ball-and-socket joint, and
cause it when acted upon by the rolling of the vessel to travel in a circuit by
means of a circular guide and check rod, or other suitable arrangement. Then
by connecting the upper end of the rod to a crank, or its equivalent, rotatory
motion available for a variety of uses may be derived therefrom.
The vibrating pendulum during calm weather may be worked by one
or more lanyards attached to its weighted end; or it may be beneficially used
as a maintaining power by attaching it, for example, to pumps worked by the
ordinary vibrating handles.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Julius Roberts and Miles Beale in the Great Seal Patent
Office on the 11th June 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JULIUS
ROBERTS, of Saint Leonard's Iron Works, Poplar, in the County of Middlesex,
Captain in the Royal Marine Artillery, and MILES BEALE, of Surrey Street,
Strand, in the City of Westminster, Navy Agent, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters 35
Patent, bearing date the Eleventh day of December, in the year of our. Lord

page_text: One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Julius Roberts and Miles Beale, Her special license that we, the said
Julius Roberts and Miles Beale, our executors, administrators, and assigns,
or such others as we, the said Julius Roberts and Miles Beale, our execu-
tors, 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 "IMPROVED MACHINERY FOR OBTAINING AND
APPLYING MOTIVE POWER, APPLICABLE CHIEFLY TO THE WORKING OF SHIPS'
PUMPS, AND OTHER MECHANISM ON SHIPBOARD," upon the condition (amongst
others) that we, the said Julius Roberts and Miles Beale, by an instrument
in writing under our hands and seals, or under the hand and seal of
one of us, 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 Miles Beale, on behalf of myself
and of the said Julius Roberts, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement,
reference being had to the Drawings hereunto annexed, and to the letters and
figures marked thereon (that is to say) :-
This Invention relates to the use of a weighted rod for transmitting a
driving power to machinery. We propose chiefly to apply our Invention to
the working of ships' pumps, capstans, and to other like uses on shipboard,
as we are then enabled to avail ourselves of the rolling motion of the vessel
to generate motive power.
In the accompanying Drawings we have shewn two arrangements for
carrying our Invention into operation.
When adapting the Invention in the simplest form to produce a recipro-
cating motion suitable for working a pair of pump pistons, we propose to.
employ the arrangement shewn in elevation at Fig. 1, wherein the pendulum
rod a, weighted at its lower end, is shewn as suspended by a ball-and-socket
joint 6, midway between a pair of horizontal pump cylinders c, c. The upper
end of the pendulum rod a is jointed to the piston rods d,. d, which are
themselves jointed to the pistons of the pump cylinders to give the requisite

page_text: play to the piston rods. As, therefore, the vessel rolls, the inertia of the
weighted rod or pendulum will impart an alternating action to the pistons.
Fig. 2 shews in side elevation, and Fig. 3 in plan viow, another mode of.
carrying out our Invention. In this arrangement it will be seen that a rotary
motion is obtained which might, if required, be applied directly to the driving
of machinery, or, as illustrated by the Drawing, be converted into a recipro-
cating motion for the purpose of working a reciprocating ship's pump. a, a,
is the pendulum carried by a ball-and-socket joint, which is supported on the
deck of the vessel; the upper' end of this rod projects through à slot in a.
T-shaped rocking lover b, which is capable of turning freely on a fulcrum pin
c, carried by a standard or support that is hinged to the deck and is free to
move on its fulcrum as the vessel pitches. Jointed to the opposite extremities
of the lever bare pawles d, d, which are intended to take respectively into the
teeth of a pair of ratchet wheels e, e, and impart rotary motion thereto. These
wheels are keyed to a horizontal shaft f, which carries also a spur wheel g,
the shaft having suitable bearings in the side frames h, h; above this shaft
and in a line therewith a crank shaft i is mounted in suitable bearings in the
same sido frames; this shaft carries a spur pinion which gears into the
spur wheel g,
for the purpose of receiving motion therefrom, and transmitting
it through the crank shaft to the pair of double-action pumps in connection
with the driving machinery; the pistons of these double action-pumps are
connected respectively by links to the beams 1, which are mounted on rock
shafts m that have their bearings on the pump case. Keyed to each of these.
rock shafts is an arm n, and these arms are connected by means of rods o, o,
to the crank shaft i (Fig. 2). The apparatus boing set in the ship in the
line of the keel, the pitching of the ship will cause the pendulum to draw
back the pawles and turn the ratchet wheels. In like manner, when, by the,
rolling of the ship, the pendulum imparts a rocking motion to thọ lover b, as
indicated by the red lines in Fig. 3, tho pawlos will alternately act upon the
ratchet wheels e, e, and give a slow rotary motion to their shaft f. By means
of the gearing g, k, the speed will be multiplied and communicated 'to, the
crank shaft i, the rotation of which will, through the connecting rods, arms,
and beams before mentioned, impart the required reciprocating motion to the
pistons of the punips. It will be obvious that this motion may be com-
municated directly, or by gearing to a capstan, or windlass barrel, or other
mechanism required to be driven.
In some cases; when it is desired that the weighted rod shall impart a
rotary motion to machinery, it may be mounted in gimbals, or suspended in a
ball-and-socket joint, and caused, when acted upon by the rolling, of the
.

page_text: vessel, to travel in a circuit by means of a circumscribing circular guide or
its equivalent; then, by connecting the upper end of the rod to a crank, rotary
motion available for a variety of uses may be derived therefrom. During
calm weather the pendulum may be set in motion by the use of one or more
lanyards attached to its weighted end and operated by the crew; or it may
be beneficially used as a maintaining power by attaching it, for example, to
pumps worked by hand by the ordinary vibrating handles.
Having now set forth the nature of our Invention of improved machinery
for obtaining and applying motive power, we wish it to be understood that
under the above in part recited Letters Patent we claim the use of a sus-
pended weighted rod or pendulum, for imparting motive power to ships'
pumps and other mechanism required to be driven.
In witness whereof, I, the said Miles Beale, have hereunto set my
hand and seal, the Eleventh day of June, in the year of our Lord
One thousand eight hundred and fifty-eight.
