page_text: LETTERS PATENT to Samuel Povah, of Liverpool, in the County of Lan-
caster, Engineer and Tool Maker, for the Invention of "AN IMPROVED
COMBINED PORTABLE STEAM ENGINE, WINCH, AND APPARATUS OR MACHINERY
FOR OPERATING THE PUMPS AND PARTS OF THE RIGGING, WARPING, RAISING
THE ANCHOR, AND FOR OTHER USES ON BOARD SHIPS WHERE POWER 18
REQUIRED, PARTS OF THE SAME BEING APPLICABLE FOR LIKE USES SEPARATELY.”
Sealed the 11th January 1861, and dated the 11th July 1860.
PROVISIONAL SPECIFICATION left by the said Samuel Povah at the
Office of the Commissioners of Patents, with his Petition, on the 11th
July 1860.
I, SAMUEL POVAH, of Liverpool, in the County of Lancaster, Engineer and
Tool Maker, do hereby declare the nature of the said Invention for "As
IMPROVED COMBINED STEAM ENGINE, WINCH, AND APPARATUS OR MACHINERY FOR
OPERATING THE PUMPS AND PARTS OF THE RIGGING, WARPING, RAISING THE ANCHOR,
AND FOR OTHER USES ON BOARD SHIPS WHERE POWER IS REQUIRED, PARTS OF THE
SAME BEING APPLICABLE FOR LIKE USES SEPARATELY," to be as follows:-
My Invention, as stated in the title, relates to an arrangement of known
and new mechanical constructions by which various operations on board and
in connection with ships can be facilitated. Hitherto in sea-going vessels, and
especially in large sailing ships, the various operations of loading, unloading,

page_text: warping, working the pumps and rigging, raising the anchor, and others, have
been performed principally by manual labour. I now propose accomplishing
such work by substituting the combined machinery or mechanical parts herein-
after described, either placed in the vessel, or on the quay alongside. My
combined engine is more particularly applicable for use on board ships; yet
several of the connections and constructions may be used separately, and be
operated by other power; these will be more fully mentioned hereafter, and I
will now proceed to describe,―
1st, the steam boiler, which is of the upright class, fastened to a metal sole
plate on one end of a strong framing, provided with ring bolts for lashing to
the deck, and resting on suitable wheels and bearings; the top is dome-
shaped, with the usual appintenances; the bottom is similar in shape to that of
a wine bottle; the smoke is carried off by a flue lower than the furnace bars.
2nd, the steam engine, which consists of a cylinder and the usual ac-
companyments, is bolted to the side of the boiler last described; the end of the
piston rod is connected to the winch, or an intermediate shaft; if to the latter,
it gears with the winch; the piston rod is provided with suitable guides.
3rd, the winch, which is fixed on the opposite end of the framing from the
boiler, has strong sides or supports, and may be either single or double
purchase, and have the ordinary connections.
And, 4th, the appliances for operating with ropes or chains, which are fixed
on the winch barrel shaft, consists of a series of pullies with vee-shaped
periphreys, notched or having raised pieces on each side alternately in the
vee groove all round, to prevent the ropes or chains from slipping. By passing
a rope once round any of these pullies, the slack end being kept clear,
sufficient hold will be taken for general operations. Where a chain or rope is
made to work over two of these pullies, as arranged for pumping, the one
being on the combined machine, the other on the pump crank shaft, they may
stand at a considerable angle to each other.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Povab in the Great Seal Patent Office on the 11th
January 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
POVAш, of Liverpool, in the County of Lancaster, Engineer and Tool Maker,
send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of July, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Samuel Povab, Her special licence that I, the said Samuel Povah, my
executors, administrators, and assigns, or such others as I, the said Samuel
Povab, 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 "AN IMPROVED COMBINED PORTABLE
STEAM ENGINE WINCH, AND APPARATUS OR MACHINERY FOR OPERATING THE PUMPS
AND PARTS OF THE RIGGING, WARPING, RAISING THE ANCHOR, AND FOR OTHER USES
ON BOARD SHIPS WHERE POWER IS REQUIRED, PARTS OF THE SAME BEING APPLICABLE
FOR LIKE USES SEPARATELY," upon the condition (amongst others), that 1, the
said Samuel Povah, my executors or administrators, by an instrument in
writing under my, or their, or one of their bands 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 Samuel Povah, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
My Invention, as stated in the title, relates to an arrangement of known
and new mechanical constructions by which various operations on board and
in connection with ships can be facilitated. Hitherto in sea-going vessels,
and especially in large sailing ships, the various operations of loading,
unloading, warping, working the pumps and rigging, raising the anchor, and
others have been performed principally by manual labour. I now propose
accomplishing such work by substituting the combined machinery or mecha-
nical parts herein-after described, either placed in the vessel or on the quay
alongside. My combined engine is more particularly applicable for use on
board ships; yet several of the connections and constructions may be used
separately, and be operated by other power; these will be more fully mentioned
hereafter, and I will now proceed to describe,―
Firstly, the steam boiler, which is of the upright class, fastened to a metal

page_text: sole plate on one end of a strong framing, provided with ring bolts for lashing
to the deck, and resting on suitable wheels and bearings; the top is dome-
shaped, with the usual appurtenances; the bottom is similar in shape to
that of a wine bottle; the smoke is carried off by a flue lower than the
fire bars.
Secondly, the steam engine, which consists of a cylinder and the usual
accompanyments, is bolted to the side of the boiler last described; the end of
the piston rod is connected to the winch on an intermediate shaft; if to the
latter, it gears with the winch; the piston rod is provided with suitable guides.
Thirdly, the winch, which is fixed on the opposite end of the framing from
the boiler, has strong sides or supports, and may be either single or double
purchase, and have the ordinary connections.
And, fourthly, the appliances for operating with ropes or chains, which are
fixed on the winch barrel shaft, and consists of a series of pullics with vee-
shaped peripheries, notched, or having raised pieces on each side alternately in
the vee-groove all round, to prevent the ropes or chains from "slipping." By
passing a rope once round any of these pullies, the slack end being kept clear,
sufficient hold will be taken for general operations. Where a chain or rope
is made to work over two of these pullies, as arranged for pumping, the one
being on the combined machine, the other on the pump crank shaft, they may
stand at a considerable angle to each other.
But in order that my said Invention may be more perfectly understood and
explained in detail, I have hereunto attached a Sheet of Drawings representing
my improvements, and having on the several views the same letters of
reference marked on similar parts of the machinery or apparatus.
Fig. 1 represents an end elevation; Fig. 2, a side elevation; Fig. 3, a plan
view; Fig. 4, a vertical section of the boiler; and Fig. 5, an end view of one
of the chain pullies on an enlarged scale.
a shews the framing made of timber; b, the wheels and axletrees; c, ring
bolts for lashing or making fast to the deck; d, the boiler, shewn fastened to
the wooden framing, sheathed with mall iron plates, but which may be secured
on a cast-iron sole plate made fast to the framing by bolts; e, the man-hole;
f, the safety valve; g, the steam pressure gauge; h, the water gauge ; i₁ tap
for supplying hot water, which may be used, when a tube is affixed, for
extinguishing the fire, and for various other purposes. A similar tap com-
municating from the steam space may be used for obtaining fresh water at
sea, for extinguishing fire in the hold, for cooking, and for numerous operations.
j, the furnace; k, the furnace door; 7, the fire-bars; m, the chimney, with

page_text: regulating damper n affixed therein; o, the ash-pan, shewn in Fig. 4
partially withdrawn, in which position it admits more air under the fire-bars.
a', the steam cylinder, with steam chest and valve operated in the usual
manner by an eccentric and rod 61; c', the steam supply pipe carried from the
highest part of the boiler, and fitted with a slide valve or cock d¹; e', the slide
valve lever; f, the piston rod, having a guide-piece g' dovetailed and moving
in the slide h; 2, the connecting rod; ³, the crank, shewn secured to the
intermediate shaft k', which has a toothed pinion l¹ keyed thereon to gear
with and communicate motion to the winch barrel shaft; m², the fly wheel;
n', the feed pump; o', the exhaust pipe, terminating in the chimney.
a², strong cast-iron framing, secured to the timberwork and to the boiler
for carrying the winch shaft 6, which is exhibited as a single purchase; c³, the
driving wheel keyed to the shaft; d², the winch barrel, which can be geared
and ungeared by the clutch e² moving on a feather on the shaft, or by the
winch barrel sliding, the clutch being stationary; f, the brake, especially
suitable for lowering weights; g*, a spring to keep the brake out of acting
when not required.
a³, the grooved pullies or appliances for working with chains, secured to
both ends of the winch shaft; b, studs to prevent the chains from slipping
when hoisting sails, or such like operations subject to jerking; c, the grooved
pullies or appliances for working with ropes, which are also keyed to the winch
shaft. It will be seen that the chain and rope appliances can be used
independent of the winch, and this is of great importance, as in the event of
pumping, the full power of the engine can be obtained, whilst the form and
construction of the chain and rope pullies is such that the engine will seldom
require to be moved; a considerable angle from the driving pulley to another
or to any part operated upon will not prevent a continued and sure com-
munication of motion.
Having now described the nature and particulars of my said Invention, and
the mode of operation, I would have it distinctly understood that I do not
confine myself to the exact details laid down, as they may be variously modified
without departing from the combination of parts and principle of action; but
what I desire to claim as my Invention, and which, to the best of my know-
ledge and belief have not been hitherto used within the realm, is,-
Firstly, the combination and arrangement of portable machinery for the
purposes set forth, all as herein described and illustrated in the accompanying
Sheet of Drawings.
And, secondly, the application of chain and rope pullies, constructed as

page_text: herein described, for performing or facilitating various operations on board
ship, either used in connection with the other parts, or separately.
In witness whereof, I, the said Samuel Povah, have hereunto set my
hand and seal, this Ninth day of January, in the year of our Lord
One thousand eight hundred and sixty-one.
Witness,
JOHN T. KING.
