PROVISIONAL SPECIFICATION left by the said Charles George Wilson
at the Office of the Commissioners of Patents, with his Petition,
on the 21st June 1871.
I, CHARLES GEORGE WILSON, of Bayswater, in the County of Middlesex,
Civil Engineer, do hereby declare the nature of the said Invention for.
"IMPROVEMENTS IN MACHINERY FOR PRESSING COTTON AND FOR CRUSHING AND
PRESSING OTHER SUBSTANCES, THE SAID MACHINERY BEING ADAPTABLE FOR Loco-
MOTION ON RAILWAYS OR ON COMMON ROADS," to be as follows :—
My Invention relates to improvements in the construction of very
powerful portable presses (horizontal preferred), worked, by preference,
by hydraulic pressure or hydraulic and screw pressure, such presses:
being connected and worked by or from traction or portable engine.
power, carrying the hydraulic press, pump or pumps, or other motor for

page_text: working or driving of the presses, and the said arrangements being
capable of being employed (when required) for any other useful purpose,
such as driving cotton gins, cotton cleaning machinery, hullers, or other
machinery, for which a power of this nature can be usefully employed;
by which Invention I obtain great strength, power, and lightness in
weight by the disposition of the material and the application of steel
in construction, and also obtain increased space by the expanding
box arrangement (hereafter described) for holding very compressible
material, such as cotton for instance, that is to say, the box for holding
the compressible material to be pressed, is built up in two parts having
upper and lower spaces giving a short length of machine and great
internal capacity. The longitudinal sides of the lower box space arc
tension plates, in place of bolts or columns, stiffened inside with angle
and T iron, and lined with teak, firmly securing the ends together, which
form the hydraulic girders or hydraulic and screw girders for working
the two inside followers of the press. The frames for the upper space
or spaces are built up thereon with T, angle, and sheet iron, the two
sides being enclosed transversely, the top of which forms the expanding
and closing head plate or plates, worked by screw, crank, steam, or
hydraulic power. up and down, forming likewise when down a top to the
lower space, the longitudinal sides being doors for filling purposes. At
the lower box space transversely the baling openings are strengthened
by rectangular castings, the doors hingeing upon one and closing
against the other. These baling doors are secured by links passing from
top door to bottom on each side between the tension side plates and
the inside hinged plates for relieving the lateral pressure of the bale.
These doors when closed are, by preference, secured by bolts placed
transversely beneath, which can be easily released when under pressure.
The box underneath is enclosed, having openings or spaces near each
end for the passage of gunny bags or other wrappers of the bales upon
return of followers.
.
For working the hydraulic cylinder, or hydraulic and screw arrange-
ments, connections, valves, gearing, and shafting to and beneath each
press are provided, having clutches for forward and return motion
of the follower. The power arrangement for driving and working the
same, and which carry the hydraulic pump or pumps, is connected to
the presses by gearing and 'shafting to drive the screws, making the
whole complete and useful for any other useful purpose when discon
nected from the press or presses, as for driving cotton gins or other

machinery, or for haulage purposes, and so forth. Each press and steam
power being carried on wheels for convenience of being moved from
place to place, will be very useful in pressing and baling cotton in
India in the cotton districts at the grower's own door, similarly to
5 thrashing machines as used in England; thus enabling the cultivator to
press and bale (as well as to gin the cotton on the spot) ready for
shipment. The whole machinery being complete in itself no buildings
or expensive erections being needed, simple roofing being all that is
required at any time to protect the workers and any connected
machinery, which can be driven from shafting carried on standards,
independent of any structure.
power and
Principal points in my present improvements I consider to be the
following:-My object in devising my present improvements having
been to construct machinery capable of being transported from place
to place in a fit state for use, and then worked independent of either
foundations or buildings, so that I might apply a powerful class of
machinery for the purpose stated, having hydraulic, screw, and steam
power arrangements, which may be combined up to a certain
size, being carried upon the same frame and wheels. Beyond which to
give all necessary power, size, lightness, short length of, machine, and
portability, the engine power with hydraulic pump or pumps and
driving arrangements being carried on separate frame and wheels, when
united or connected forming one complete whole; the power being
available for working two or more presses, and utilized for other
purposes.

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 Charles George Wilson, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement:-
My Invention relates to improvements in the construction of very
powerful portable presses (horizontal preferred) worked by preference

page_text: •
by hydraulic pressure or hydraulic and screw pressure, such presses
being connected and worked by or from traction or portable engine
power carrying the hydraulic press pump or pumps or other motor for
working and driving of the presses, and the said arrangements being
capable of being employed (when required) for any other useful purpose,
such as driving cotton gins, cotton cleaning machinery, hullers, or other
machinery for which a power of this nature can be usefully employed,
by which Invention I obtain great strength, power, and lightness in
weight by the disposition of the material and the application of steel in
construction, and also obtain increased space by the expanding box
arrangement (hereafter described) for holding very compressible material,
such as cotton for instance, that is to say, the box for holding the com-
pressible material to be pressed is built up in two parts having upper
and lower spaces, giving a short length of machine and great internal
capacity. The longitudinal sides of the lower box space are tension
plates in place of bolts or columns stiffened inside with angle and T iron
and lined with teak, firmly securing the ends together which form the
hydraulic girders or hydraulic and screw girders for working the two
inside followers of the press. The frames for the upper space or spaces
are built up thereon with T, angle, and sheet iron, the two sides being
enclosed transversely, the top of which forms the expanding and closing
head plate or plates worked by screw, crank, steam, or hydraulic power
up and down, forming likewise when down a top to the lower space,
the longitudinal sides being doors for filling purposes. At the lower box.
space transversely the baling openings are strengthened by rectangular
castings, the doors hingeing upon one and closing against the other.
These baling doors are secured by links passing from top door to bottom
on each side between the tension side plates and the inside hinged plates
for relieving the lateral pressure of the bale. These doors when closed
are by preference secured by bolts placed transversely beneath, which
can be easily released when under pressure. The box underneath is
enclosed, having openings or spaces near each end for the passage of
gunny bags or other wrappers of the bales upon return of followers.
For working the hydraulic cylinders, or hydraulic and screw arrange-
ments, connections, valves, gearing, and shafting to and beneath cach
press are provided, having clutches for forward and return motion of the
follower. The power arrangement for driving and working the same,
and which carry the hydraulic pump or pumps, is connected to the

page_text: presses by gearing and shafting to drive the screws, making the whole
complete and useful for any other useful purpose when disconnected
from the press or presses, as for driving cotton gins or other machinery,
or for haulage purposes, and so forth. Each press and steam power
being carried on wheels for convenience of being moved from place to
place will be very useful in pressing and baling cotton in India in the
cotton districts at the grower's own door, similarly to thrashing machines
as used in England, thus enabling the cultivator to press and bale (as
well as to gin the cotton on the spot) ready for shipment. The whole
machinery being complete in itself no buildings or expensive erections
being needed, simple roofing being all that is required at any time to
protect the workers, and any connected machinery which can be driven
from shafting carried on standards independent of any structure.
Principal points in my present improvements I consider to be the
following:-My object in devising my present improvements being to
construct machinery capable of being transported from place to place
in a fit state for use, and then worked independent of either foundations
or buildings, so that I might apply a powerful class of machinery for the
purpose stated having hydraulic, screw, and steam power arrangements
which may be continued up to a certain power and size being carried
upon the same frame and wheels, beyond which to give all necessary
power, size, lightness, short length of machine and portability the
engine power with hydraulic pump or pumps and driving arrangements
are carried on separate frame and wheels, when united or connected
forming one complete whole, the power being available for working two
or more presses and utilized for other purposes.
In attaining the above object the following points have to be attained
and these are therefore the principal points in my Invention.
1. Obtaining the power for working the presses by the herein-before
mentioned powerful screw or screws and hydraulic power combined a
or by hydraulic power only.
2. The expanding box arrangements, and dispensing with columns,
heavy long hydraulic cylinders, and other parts.
3. The arrangements for working at both ends of the machine and

arrangement.
I will now proceed to describe my improvements by reference to thán
the expanding press box machine worked by hydraulic power.
Figs. 3 and 4, Sheet 2, show longitudinal elevation and half plan of
expanding press box machine worked by geared cranks, screws, and
hydraulic power.
Figs. 5 and 6, Sheet 3, show longitudinal elevation and half plan of
the steam transit engine power and hydraulic arrangements for working
the presses.
Description of Figs. 1 and 2, Sheet 1.-The press box space is built
and framed together in three sections 1, 2, and 3, the longitudinal
side plates A and B are lengths of steel of different thicknesses of
plates but of sufficient calculated strength and sectional area to bear
over three times the greatest working strain the part may be sub:
jected to from its own working end, each part being independent of
the other. The sides are stiffened within by angle iron at the upper
and lower edges of the plates and in the centre with the guide angle
or T iron and lined flush with teak. The ends of the lower space are
formed by the hydraulic girder castings C and D firmly secured and
held together by the side plates passing through the slotted ends in
castings, lapped beyond with short pieces of plate a, a, and bolted
together sufficiently to resist the shearing strain in proportion to the
strength of the rest of the machine. The middle of the box carries the
rectangular casting E through which passes in the slotted ends both
thicknesses of the side plates A and B, the same are secured by lap
pieces b, b, bolted to and beyond as before. The baling doors F close
against this casting and hinged upon a similar casting G on the opposite
side of the baling opening having a clear and sufficient space between
for facility of hooping and lashing and egress of bale from the press. The
upper expanding box space 1 is framed up from the lower side plates A
upon uprights C, C, bolted to the upper inside stiffening angle iron

page_text: •
enclosed as shown by sheet iron and stiffened with teak, the longitudinal
sides are doors H provided on both sides for filling purposes hinged to
uprights C, C, opening or closing and secured by bolt arrangement as
shown. Within this space 1 a head plate M ascends and descends
forming the top when up or down to the upper or lower spaces 1 and 2
worked by a small hydraulic arrangement K, with double motion guided
and held in position by frame L, bolted to the upright bolts C, C.
The cylinder K is bolted to the head plate M and rises or descends in
side guides with it, the ram bolt being stationary is secured to boss N
by lock nuts d, d, at top and bottom. A communication with the
interior for lifting motion is through the ram bolt O to an annular
space between cylinder and bolt. The communication for holding down
or forcing to the small extent required is through a channel in the
side of cylinder K, and rod pipe e secured by lock nuts to small boss u.
The lift is regulated to precisely the height and depth required, in
the lower chamber especially, the head plate being kept straight
without bulge in the centre when lapping half an inch over the upper
stiffening angle iron when close down on the lower space. This bead
plate M. need not in order to perform its duty of compressing the elastic
material at this stage be otherwise than comparatively light in con-
struction; as for instance, half inch plate stiffened with teak on top,
or both top and bottom. Arrangements are shown of rack pinion and
bevel gear ff, in corners for keeping the head plate horizontal in
ascending or descending, one or more cylinders however may be used,
if preferred; a pall to one pinion secures the rest from rising. Through
the centre rectangular casting E pass two or more sliding bars g, g,
which receive the thrust of the greater hydraulic power, lowered or
lifted by gearing readily in or out of position behind the follower P
in 2 space on the completion of the travel of the smaller horizontal
hydraulic rams R, relieving that end of the press box and cylinders from
strain. Upon releasing the pressure on the bale by the opposite
hydraulic power S, S₁, the slides are lifted and the follower P. returns.
The baling doors F, F₁, are hinged, top and bottom, to a rectangular
casting G, the spindles S** passing through the hinged portion of
the doors, and casting above and below project beyond the sides a
sufficient length to carry the geared segmental spur wheels T, T, the
weight being counterpoised and opening freely by small amount of
manual exertion. A strong link U and stud arrangement is provided,
passing from the studs in boss on top door on each side to the lower

page_text: door in the space between the moveable plate V and side frames, and
a strong eccentric lever bolt arrangement h is provided beneath the lower
door, securely holding the doors under the greatest pressure, and capable
of being released easily by lever and chain arrangement i. For removal
of lateral pressure from the end of bale and press, strong moveable sido
hinged plates V are provided, hinged j,j, on one or both sides of box
between the two rectangular castings E and G, above and below, the
same width as the openings. These plates V, when the lower door F
is closed, are forced up into position flush with the interior width of the
castings and teak lining inside. When the pressure on the bale is
removed they descend by weight of bale in passing out. The end girder
casting C receives the smaller diameter hydraulic cylinders W (with
rams secured to follower P) in bosses, and are each held by key or
keys k in position when out. Each cylinder W is recessed for gland and
ring for easy renewal of leathers, secured by stud or T-headed bolts.
A small independent hydraulic arrangement is shown for return of
follower, but return motion may be obtained from the same cylinders
and rams. Pipes, connections, stop valves, and arrangements are shown
to convey the hydraulic pressure from engine at orifice X. The girder
casting D at the finishing end (with rams secured to follower Y) is
formed with and is part of the hydraulic cylinders, of the required
number and diameters, or. it may be so formed as to receive the cylinders
in bosses as at the other end, secured by key or in other suitable manner.
Each cylinder is recessed for gland and ring as before, and secured by
stud or T-headed bolts. A. self-acting arrangement may be provided,
similar to the other end for return of follower, or by return motion to
the centre ram. Pipe connections, stop valve arrangements are shown
to convey the hydraulic pressure from engine at orifice X. On the
forward motion of the centre ram S the two outside cylinders fill from
the small tank Z above on girder casting, having access to the interior
of the cylinders by reverse valves which close on the pressure from
the hydraulic pump, being admitted upon the travel of the centre ram
a certain distance forward. To the follower blocks P and Y are bolted
the slot plates p and y, sufficiently grooved for the passage of hoops or
lashing and slightly curved in face for the purpose of preventing
expansion on the baling doors being opened. These blocks and plates
have half inch clearance at top and bottom of box for passage of
gunnies, and grooved in centre of both ends to slide on the centre guide
angle or T stiffening irons on side plates projecting one inch, more or less,

page_text: within space. On one or both sides outside of press a platform is carried
(available for and between two presses) by a light girder arrangement,
dropped in and held in position by the holdfast irons r, r, on the middle
and end castings; on this planked platform is carried a simple angle-iron
rail, on which runs a filling box with the weight of cotton to be pressed.
A ladder incline is hinged to a weighing machine below and to the
above platform girder, upon which the filling box is moved up and
down, a self-acting arrangement m for signalling is shown worked from
the follower; waste pipe 5 conveys the fluid back to a small tank
beneath the engine power 6, 6, 6, constant pressure piping supplied
from orifice X to work return motion; 7, junction for supplying pressure
to hydraulic cylinder lift ram; the whole machinery is supported on
wheels,, for being transported from place to place, rings or flanges
in segments bolted to the tyres and horn plates, bolted to the side plates
at the other end to receive ordinary railway waggon wheels and journals
instead, adapts the whole to rail or road when required.
The operation is performed as follows in the shortest possible time :-
The gunnies having been placed on the followers-P and Y at both ends
the cotton is discharged into the press through the door of the expand-
ing box H. The doors are closed and secured by bolt arrangement S.
Upon the stop valve arrangement & being reversed allowing the fluid
to escape by waste pipe w the head plate M quickly descends by its
own weight on to the elastic substance, compressing in bulk the fibre
into the lower space box 2, any extra power required to close or press
down the head plate is simply obtained by admitting the pressure into
cylinder K below by opening the stop valve t. Upon the stop valve u
being opened the quick low hydraulic pressure is conveyed by pipe x
to the long cylinders W. The rams R force forward the follower P
the required distance it has to travel. The slides g, g, are now run
down behind follower P; the pressure at this point exceeding the low
pressure passes by weight or spring lever piston valve y to centre
ram at short cylinder end, which forces forward follower Y a certain
distance; the pressure at this point exceeding its middle pressure passes
by weight or spring lever piston valve y¹ to the two outside cylinders,
which have been up to the pressure being admitted filling by reverse a
valves from small tank above. The bale being now compressed to
the smallest required size the stop valve u is closed, and the hydraulic
pressure is available for other presses by connection of piping to orifices Z.
The doors F, F, are thrown open, and the bale bound by hoop iron

page_text: we pressure being released from одоwer I
by opening the waste stop valve arrangement 4a and 4b, which conveys
back the fluid to small tank Z above cylinder casting by pipe 5a; the
weight of the bale immediately descends beneath by the dropping of
the moveable binge side V%; the doors are again closed, moving up
the hinged side, the followers return, and the operation continues as
before.
In Figs. 3 and 4, Sheet 2, which show longitudinal elevation and half
plan of expanding press-box machine worked by geared cranks, screws,
and hydraulic power.
The arrangements in the Figs. 3 and 4, omitted to be described in
the following statement of parts, are similar in construction and action,
and the same letters refer to the same parts. It is therefore only
necessary to describe those parts which differ in construction, that is
to say :-
Figs. 3 and 4, Sheet 2.-The press box space is built and framed
together in two sections 1 and 2. The longitudinal side plates A. are one
length of steel, each side the same thickness throughout from end to end.
The ends of the lower space are formed by the hydraulic and screw
girders C and D. The middle of the box carries the rectangular casting E,
through which passes in the slotted ends the side plates A; the same
is kept in position by bolts or by lapped pieces on to the side plates.
Within the space 1 a head plate M ascends and ascends forming the top
when up or down to the upper or lower spaces 1 and 2 by a double
crank W arrangement in two slotted castings 20, wo, bolted to the top of
the head plate, and worked by spur gear K and endless screw arrange-
ment capable of being thrown in or out of gear to allow the head
plate M to descend quickly on to the loose substance by its own weight.
The endless screw arrangement L now thrown into gear with the spur
wheels K. gives the requisite pressure to close down the head plate on the
elastic substance by bringing the cranks W over to the lowest vertical
position. The whole is thus securely held, forming the top of the lower
space 2. The end girder casting C of such proportionate strength to
resist over three times the greatest working strain is secured, as before
stated, to the side plates, and carries the long internal revolving nuts with
screws R and spur gear 3 and 4 driven from the shaft beneath by mitre
wheels and pinion arrangements 6. The driving shaft is connected by
"

page_text: forked point arrangement S* to the engine power. On this shaft slides
on key the double and single coned friction clutches for forward and
return motion of the follower, the outside double conc for forward
motion with the pressure is of as large diameter as the gear will admit,
and the single cone for return of follower is only of small diameter.
The double threaded screws R are keyed in the bosses of the follower P
or bolted thereto. A self-acting arrangement is shown for throwing
out of gear the friction cones on completion of the travel of the screws R
and follower P within the space. The screws at this point now become
short columns for the thrust of the greater hydraulic power.
:―
The operation is performed as follows in the shortest possible time :-
The gunnies having been placed on the followers P and Y at both ends
the cotton is discharged into the press through the door of the expanding
box H. The doors are closed and secured by bolt arrangement S, as
before. The head plate M is now moved over the top centre of the
cranks W, and quickly descends by its own weight on to the elastic
substance, compressing in bulk the fibre into the lower space box 2.
Any extra power required to close or force down the head plate M is
simply obtained by bringing over the cranks W to the lowest vertical
position by the spur and endless screw gear arrangement K, L, securing
and fastening the same, which then forms the top to the lower 2 space.
The friction clutches being now thrown or forced into gear the follower P
is run forward by the screws R the required distance it has to travel.
The screws R now become short columns behind follower P, the stop
valve u being opened the hydraulic pressure passes to the centre ram S¹
which forces forward follower Y a certain distance, the pressure at this
point exceeding its low pressure passes by weight or spring lever piston
valve y¹ to the two outside cylinders which have been up to the pressure
being admitted filling by reverse valves from small tank above.
The
bale being now compressed to the smallest required size the stop valve u
is closed, and the power and also hydraulic pressure are available for
other presses by connections of piping to orifice *.
The doors F, F',
are thrown open, and the bale bound by hoop iron bands or lashing.
Upon the pressure being released from the follower Y by opening the
waste stop valve 4a which conveys back the fluid to small tank Z above
cylinder casting by pipe ba, the weight of the bale immediately descends
beneath by the dropping of the moveable hinged side V; the doors are
again closed, moving up the hinged side V%; the screws and followers

page_text: return by the small friction clutch 7 upon being thrown into gear, and
the operation continues as before.
In Figs. 5 and 6 Sheet 3 which show longitudinal elevation and half
plan of the steam transit power and hydraulic arrangements for working
the presses herein-before described. The longitudinal frame A of the
engine is constructed of two side plates with ends secured by angle iron
bolted in corners, and further strengthened by angle iron bars a, a, lapping
over each side and bolted to the frames to which is attached the link and
pins; b, b, chains and hooks for haulage and other suitable purposes.
The boiler B is carried at one end of the frame, the fly wheel crank
