Year: 1840

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
HORATIO SIMPSON, of No. 6, New Palace Yard, Westminster, in the County
of Middlesex, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and, Ireland, bearing date at Westminster, the Ninth day of December, in the.
fourth year of Her reign, did, for Herself, Her heirs and successors, give, and
grant unto me, the said Alexander Horatio Simpson, my exors, adiñors, and
assigns, or such others as I, the said Alexander Horatio Simpson, my exors;,
adiñors, or assigns, should at any time-agree with, and no others, from time to
time, and at all times during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within England; Wales, the
Town of Berwick-upon-Tweed, and also within all Her said Majesty's-
Colonies and Plantations abroad, my Invention of "AN IMPROVED MACHINE OR.
APPARATUS FOR WORKING PUMPS;" in which said Letters Patent is contained a
proviso obliging me, the said Alexander Horatio Simpson, by an instrument.
in writing under my hand and seal, particularly to describe and ascertain the
nature of my said Invention, and in what manner the same is to be performed,"
and to cause the same to be enrolled in Her said Majesty's High Court of
Chancery within six calendar months next and immediately after the date of
the said in part recited Letters Patent; as in and by the same, reference being
thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Alexander Horatio Simpson, do hereby declare that the nature of my said
Invention consists of a pendulum or a moveable weight fitted to a bar which
is suspended on an axis, and capable of vibrating after the manner of a
pendulum, and as herein-after described, having suitable mechanism attached
thereto for communicating the required motion to a pump or pumps, the said
motion being obtained either by placing the machine containing the pendulum
on a body in motion, such as the deck of a ship, as herein-after explained, or
by keeping the said machine stationary, and allowing the wind to cause the
vibration of the pendulum, as also herein-after described, the stroke of the
pumps being in both cases caused by the tendency which the pendulum has to
preserve its perpendicular position while the pumps and the frame to which it
is attached are in motion, or while the pendulum itself is acted upon by
wind, as herein-after explained. And in further compliance with the said
proviso, I, the said Alexander Horatio Simpson, do hereby describe the
manner in which my said Invention is to be performed, by the following state-
ment thereof, reference being had to the two Drawings annexed, marked A
and B, and to the figures and letters marked thereon, that is to say:―
DESCRIPTION OF THE DRAWINGS.
And first with reference to my said apparatus, as applied to ships' pumps.
The construction of the pendulum (with regard to length and weight), and the
machine in general, must of course be adapted to the craft in proportion to
the tonnage or build; and it will be seen I am thus enabled to apply to a
useful purpose the motion of the vessel, which cannot be avoided, and effect
the saving of much manual labour.
Figures 1 and 2 represent an elevation and end view. In both Figures
similar letters are used to denote similar parts. A represents the pendulum,
and B the weight, which I generally make capable of sliding on the pendulum
bar so as to be fixed at different distances from the point of suspension which
regulates its power and extent of vibration. The pendulum is suspended by
the pivot C, C, which works in the plummer blocks D, D, and is supported by
the framework E, which is firmly bolted to the deck of the vessel near the
pumps F, F, which are in this Figure supposed to be of the ordinary con-
struction of lifting pumps. On the spindle or pivot of the pendulum is
mounted a cross head or a cross beam G, united at the extremities by jointed
connecting rods H, H, to the handles (or lift rods K, K,) of the pumps.
l'represents the apparatus, which, when the machine is required to be at rest,
is lowered, and embraces the rod of the pendulum, as represented in Figure 1.

page_text: In Figure 2 it is shewn as drawn up, to allow the pendulum to vibrate. It is
raised or lowered by the chains L, L. M represents an arched friction bar,
against which the pendulum weight rolls, when out of the perpendicular, in a
lateral direction.
Figure 3 represents a method of applying wind as a motive power for my
pendulum, by producing a vibrating motion for it. A is a vertical shaft,
capable of vibrating on its bearings B in the framework C, which is firmly
bolted to the foundation D, which is here supposed to be on land, and
stationary. On the top of the shaft are fitted vanes E, E, mounted in the
usual manner by pins f. f, passing through their centre, so as to admit of
being feathered or brought with their edge to the wind. To the pins f. f, are
keyed levers 9, 9, at an angle of 45° with the vanes, which are connected by a
rod H passing down the shaft A, which rod is terminated by a joint con-
necting it with a lever I, fixed by a centre pin K to the shaft, on the end of
which lever is a stud L, which projects sufficiently to come within the arc on
which the other parts work clear of. Now, when the shaft is in motion, and
arrives at a certain point at either end of its vibration, the stud strikes the
guide bars n, n, and alternately is raised and lowered, and consequently the
other end of the lever, which communicates the motion through the bar H to
the levers, and vanes E, E. The parts are represented as in the position
when vibrating in the direction shewn by the arrow in red, and against the
course of the wind, as indicated by the arrows in black. The stud L, when
approaching the end of its vibration, will strike the guide bar n, and will be
forced down, thereby moving the bar H upwards, which, acting on the vanes,
brings them round for the action of the wind, which impells the shaft forward
until the stud comes in contact with the opposite guide bar n, which strikes it
down, and again feathers the vanes, the vibration being assisted by the
weight o. The effect of this arrangement is, that as the wind is constantly
varying in its force, even if it does not always drive the shaft over far enough
to one side to cause the vanes to feather, and so allow the pendulum to regain
its perpendicular position, a lull of the wind merely will often have the effect,
and so cause the pumps to work.
Now, whereas it is evident that the details of the machinery by which this
principle of working pumps by the motion of the vessel on board ships, or by
the varying force of wind on land, may be carried out, may be varied, to suit
particular circumstances of size and locality, according to the views of the
engineer engaged to erect the sanie. But what I claim as my Invention is,
an improved apparatus or machine, whereby the working of pumps is caused
by the power of a pendulum preserving its perpendicular position in one case,

page_text: while the vessel to which it is attached is in motion seeking to regain its per-
pendicular, position in the other, when acted upon by the wind, the body to
which it is attached being stationary. And such my Invention being, to the
best of my knowledge and belief, entirely new, and never before used within
that part of Her said Majesty's United Kingdom of Great Britain and Ireland
called England, Her said Dominion of Wales, and Town of Berwick-upon-
Tweed, nor in any of Her said Majesty's Colonies or Plantations abroad, I
do hereby declare this to be my Specification of the same, and that I do verily
believe this my said Specification doth comply in all respects, fully and without
reserve or disguise, with the proviso in the said herein-before in part recited
Letters Patent contained, wherefore I do hereby claim to inaintain exclusive
right and privilege to my said Invention.
In witness whereof, I, the said Alexander Horatio Simpson, have here-
unto set my hand and seal, this Seventh day of June, in the year of
our Lord One thousand eight hundred and forty-one.
ALEX HORATIO (L.B.) SIMPSON.
'AND BE IT REMEMBERED, that on the Seventh day of June, in the.
year of our Lord 1841, the aforesaid Alexander Horatio Simpson came before
our said Lady the Queen in Her Chancery, and acknowledged, the Specifi-
cation aforesaid, and all and every thing therein contained and specified, in
form above written. And also the Specification aforesaid was 'stamped
according to the tenor of the Statute made for that purpose.
Inrolled the Eighth day of June, in the year of our Lord' One thousand
