PROVISIONAL SPECIFICATION left by the said Henry Kinsey at
the Office of the Commissioners of Patents, with his Petition, on
the 3rd October 1871.
'
I, HENRY KINSEY, of Nottingham, in the County of Nottingham, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
STEAM WINCHES, PARTLY APPLICABLE TO STEAM ENGINES GENERALLY AND TO OTHER
PURPOSES," to be as follows:-
-
. My Invention has for its object an improved construction of steam
winches whereby a much more simple arrangement of the various
parts is attained, and the machines rendered much less expensive than
heretofore.

page_text: For this purpose I construct a framing composed of a bed plate and
two side uprights formed of one casting. At the back end of the bed
plate is a vertical flange, to which a horizontal steam cylinder or pair of
cylinders is or are fixed, the said flango constituting the covers to the
cylinders. From this flange a central rib passes forward to the front of
the bed plate, and to the top of this rib is fixed a plate forming the top
guides to the cross heads of the piston rods of the steam cylinders, the
lower guides being formed on the bed plate itself. The rib also carries
the central bearing of a single or double crank shaft, extending right
across the framing, and situated near the bed plate in the front part of
the winch, to which crank shaft the piston rods of the steam cylinders
are connected by connecting rods. The crank shaft has its end bearings
in the before-mentioned side uprights of the framing; it constitutes the
first-motion shaft of the winch, and carries for this purpose a loose spur
pinion (capable of being made to rotate with the shaft by a clutch) in
gear with a spur wheel fixed on the barrel shaft of the winch, which is
carried in bearings on the tops of the uprights. The ends of the crank
shaft are also made to project beyond the uprights, and on the projecting
end on the side where the before-mentioned spur gearing is situated is
fixed a spur pinion in gear with a spur wheel on the projecting end of a
second-motion shaft, which carrics inside the. upright a loose spur pinion,
which can be thrown into gear by a clutch with the spur wheel on the
barrel shaft. The other projecting end of the crank shaft may con-
veniently serve to connect any other machinery to the winch that may
require to be driven thereby.
The cross heads on the piston rods, or the guide blocks to the same
when such are employed, are formed with inclined upper and lower
surfaces, upon which are fixed adjustable wedge-shaped plates, which
are adjusted so as to fit accurately with their outer surfaces between the
guides. This simple form of adjustment for the cross heads, or for the
guido blocks thereto, between the guides is also applicable to the cross
heads and guide blocks of piston or slide rods to steam engines generally,
as also to any other description of reciprocating rods whose ends or eyes
are required to be supported by guides.
In place of fixing the steam cylinders to the winch, as above described,
I also in some cases arrange them as oscillating cylinders, with their
piston rods connected directly to the before-mentioned crank shaft.

page_text: In order to render the speed with which the winch is driven capable
of accurate regulation according to the work performed thereby, I
provide the winch with a governor for controlling the throttle valve of
the steam pipe to the steam cylinders, and I prefer to construct such
governor in the following manner :-The governor arms are formed with.
inclined surfaces, upon which a spherical.or otherwise shaped weight-
rests, with curved surfaces formed inside a slot, in which the arms move;
up and down. This weight is provided with a neck or sleeve at its lower.
end, into which takes a fork formed on a sliding piece, the lower end of.
which carries a pin working in a slotted curved lever fixed upon the.
throttle valve spindle. By this arrangement as the governor arms rise
and fall the spherical or other weight will be made to rise and fall with
them, and will at the same time cause the before-mentioned slide to
move up and down and to actuate the curved lever on the throttle valvo,
spindle. The slot in this lover is so formed that no matter what the
angular position of the governor arms may be any equal increase or
decrease of the speed at which they rotate will cause the said lever, and.
consequently also the throttle valve, to be turned through such an angle
that an accurate regulation of the admission of steam to the steam,
cylinder or cylinders according to the work to be performed will bo,
attained.
.
In place of the above-named weight a spring may be employed
pressing with curved surfaces upon the governor arms.
The above-described improved construction of governor is also appli-
cable to steam engines generally for controlling the admission of steam
to the cylinders by connecting the before-mentioned lever to the throttle
valve of the steam pipe of the engine, and by driving the spindle carrying
the governor arms from the crank shaft or other shaft of the engine
either by means of a strap. and pulley or by suitable gearing of any
known arrangement.

page_text: guides to the cross heads of the piston rods of the steam cylinders, the
lower guides being formed on the bed plate itself. The rib also carries.
the central bearing of.a single or double crank shaft, extending right
across the framing and situated near the bed plate in the front part of
the winch, to which crank shaft the piston rods of the steam cylinders
are connected by connecting rods. The crank shaft has its end bearings
in the before-mentioned side uprights of the framing; it constitutes the
first-motion shaft of the winch, and carries for this purpose a loose spur
pinion (capable of being made to rotate with the shaft by a clutch) in
gear with a spur wheel fixed on the barrel shaft of the winch, which is
carried in bearings on the tops of the uprights. The ends of the crank
shaft are also made to project beyond the uprights, and on the projecting
end on the side where the before-mentioned spur gearing is situated is
fixed a spur pinion in gear with a spur wheel on the projecting end of a
5 second motion shaft, which carries inside the upright a loose spur pinion
which can be thrown into gear by a clutch with the spur wheel on the
barrel shaft. The other projecting end of the crank shaft may con-
veniently serve to connect any other machinery to the winch that may
require to be driven thereby.
). The cross heads on the piston rods, or the guide blocks to the same
when such are employed, are formed with inclined upper and lower
surfaces, upon which are fixed adjustable wedge-shaped plates, which
are adjusted so as to fit accurately with their outer surfaces between the
guides. This simple form of adjustment for the cross heads, or for the
5 guide blocks thereto, between the guides is also applicable to the cross
heads and guide blocks of piston or slide rods to steam engines generally,
as also to any other description of reciprocating rods whose ends or eyes
are required to be supported by guides.
In place of fixing the steam cylinders to the winch as above described,
I also in some cases arrange them as oscillating cylinders with their
piston rods connected directly to the before-mentioned crank shaft.
DESCRIPTION OF THE DRAWINGS.
Fig. 1, Sheet I., represents a plan; Fig. 2, Sheet I., an end view;
Fig. 3, Sheet II:, a side view; Fig. 4, Sheet II., a longitudinal section
5 on the line Z, Z (Fig. 1); and Fig. 5, Sheet II., a transverse section on

page_text: of a steam winch constructed according to my Invention wherein two
steam cylinders A, A, are employed.
-
The framing consists of a bed plate B with two sido uprights C, C, cast
in one piece therewith. The cylinders A, A, are fixed to a flange at the
one end of the framing, this flange constituting their covers. D is a
central rib, on which is fixed a plate E forming the top guides E', E', of
the cross head F, the lower guides E³, E³, being formed on the bed plate B.
The double crank shaft G extends across the framing, and works in
bearings G¹, G', in the side uprights C, C, and in a middle bearing G³
formed on the rib D. On the crank shaft is mounted a loose pinion II, :
which gears with the spur wheel I fixed on the barrel shaft. There is
also fixed on the crank shaft a pinion K, which gears with a spur
wheel L on a counter shaft M, on which thero is mounted looso
a pinion N gearing with the spur wheel I. A pair of sliding
clutches O', 0³, aro mounted with feathers on the shafts G and M
respectively, and are worked by a lever O, which as it is moved to the
one side throws the one clutch in gear and the other out of gear with
the pinion facing it. When the clutch O' is in gear the spur wheel I
is driven directly from the pinion H on the crank shaft, or the winch
is worked with single purchase, the pinion N on the countershaft M
revolving loosely. When the clutch O³ is in gear the countershaft M is
driven by the pinion K from the crank shaft, and the pinion N drives
the spur wheel I, or 'the winch is worked with double purchase, the
pinion H in that case revolving loosely.
The cross head F is formed with inclined upper and lower surfaces, 2
on which are fixed wedge-shaped plates P, P. These plates are secured
to the cross head F by bolts passing through slotted holes in the cross
head, and by moving them longitudinally they can be adjusted on the
cross head so as to make their outer surfaces accurately fit the guides.
Although in the Drawings the guide surfaces of the cross head are 3
represented as circular arcs they might be flat, as may readily be
understood.
It may also be understood that this mode of adjusting a reciprocating
cross head between guides is applicable to steam engines generally or to
cross heads of other machines.
The other parts of the winch represented in the Drawings, such as the
barrel with its capstan ends and its brake and treddle, and the link
3

page_text: motion for the steam cylinders, may be constructed in any known
manner. Also one cylinder may be employed instead of two, as shewn
in the Drawings, the central rib D and the middle bearing G being in
that case dispensed with, and the top plate of the single guide being
supported on side ribs projecting upwards from the bed plate.
When oscillating cylinders are employed having their piston rods
connected directly to the cranks without the intervention of connecting
rods, guides are unnecessary. In such a case the cylinders, instead of
being bolted to the end rib of the framing, have their trunnions mounted
in bearings at the end of the framing cast in one piece with the
framing.
Having thus described the nature of my Invention, and in what
manner the same is to be performed, I claim,―
First. The general arrangement and construction of steam winches,
substantially as herein described.
Second. The use for steam winches of a framing consisting of a bed
plate with two side uprights cast in one therewith, and an end flange
constituting the cylinder cover or covers, substantially as herein
described.
Third. The use for double cylinder steam winches of a framing in
which a central rib supports the middle bearing for the crank shaft and
the top guide plate, substantially as herein described.
Fourth. The mode of adjusting a reciprocating cross head between
guides by means of adjustable wedge plates, substantially as herein
described.
In witness whereof, I, the said Henry Kinsey, have hereunto set
my hand and seal, this Second day of April, in the year of our
Lord One thousand eight hundred and seventy-two.
