I SAMUEL BUTLER of 127, Bute Road, Cardiff, in the County of Glamorgan,
Engineer, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN STAITHS AND APPARATUS IN CONNECTION THERE WITH FOR THE MORE RAPID
SHIPMENT OF COAL, MINERALS AND OTHER LIKE MATERIAL FROM RAILWAY
WAGONS to be as follows.
"
My Invention has reference to prior inventions for improvements in staiths and
apparatus in connection therewith for the more rapid shipment of coal minerals
and other like materials from Railway wagons, of which complete specifications
were filed by me in the Great Seal.. Patent Office on the 21st day of July 1884,
N° 10,414, and on the 7th day of August 1884, N° 11,082, and on the 12th day of
September 1884 N° 12,330.
First I refer to Patent N° 10,414 and especially to the following words therein
contained. "Instead of running the wagon off the travelling carriage into the
staith the travelling carriage may be run into the staitli with the wagon upon it
and the whole raised or lowered to the point of tipping."
The present Invention has for its object to cover improvements in moveable
staiths especially constructed to receive the travelling carriage therein referred to
and for lifting the samo with the wagon upon it to any required height for tipping.
The carriage is made in two parts, the upper portion forming the cradle which is
taken up in the lift and the lower portion forming the body of the carriage
mounted on wheels and remaining on the rails. The motion of the carriage is
effected by two hydraulic cylinders geared by racks and pinions with a short shaft
upon which are keyed two pullies. A flat wire rope is wound on each. pulley in
opposite directions and attached thereto from which they are led in opposite
directions over pulleys at each end of the line of rails on which the carriage is
required to travel.
The staith is constructed in the ordinary way, being a framework of iron well
braced together and mounted on wheels running on parallel rails. The four
corner main uprights form guides in which work two rectangular. lifting frames,
one lifting frame working in the two guides nearest the quay, and the other lifting
་

page_text: frame working in the two guides at the back. These lifting frames are provided
with feet projecting inwards for the purpose of lifting the cradle off the body of
the carriage. The lifting of these frames with a cradle upon them is effected by
an hydraulic cylinder having eight chains, their ends being fastened to the lifting
frames, four chains being fastened to one and four to the other and all passing
parallel over the top and bottom pulleys of the hydraulic cylinder.
Secondly-1 refer to my patent N° 11,032 in which are described appliances for
working my patent box by balance weights and also appliances for opening and
closing the mouth of the shoot. I now describe appliances for working my patent
box by hydraulic cylinder combined with a balance weight. For simplicity I have
dispensed with the double jib projecting over the shoot and also with the weights
on the ends of the levers for closing the mouth of the shoot, this same effect being
produced by the weight of the box and its contents by running the chains by
which it is suspended over the pulley on the ends of the levers.
In order to provide against the box running wild by careless working of the
brakes I provide for lifting and lowering it by an hydraulic cylinder-There are
two chains passing parallel to each other twice over the top and bottom pullies of
the hydraulic cylinder thence over pullies on the top of the staith and downwards
over the pullies on the shoot levers and being attached to the cross bar which in
its turn is attached to the doors at opposite sides of the box. There are also two
chains attached to the box, likewise passing over pulleys on the shoot levers and
thence over pulleys on the top of the staith and coming downwards at the back
are attached to a balance weight working on guides, the guides being also racks on
which are provided sliding stops capable of being set at any required height so as
to arrest the descent of the box at any depth-The weight of the box being thus
taken up by the chains to the balance weight, the other chains from the hydraulic
cylinder are free from tension and the doors are forced open by the pressure of the
contents of the box which is discharged into the ship. The object of this patent
is also to induce a slight alteration of the levers for opening and closing the mouth
of the shoot by the lifting up of a portion of the bottom of the shoot preferably
the end. This portion of the bottom of the shoot is kept up against the pressure
of coal by two balance weights hanging preferably at the back of the staith and
connected to the levers by chains. An hydraulic cylinder is made to serve the
double purpose of tipping the wagon and raising the end of the shoot clear of the
ships. This is effected by a rack on the top of the ram engaging in a pinion
running loose on the end of a shaft upon which are keyed two drums for winding
up the chains passing over pulleys on the top of the staith and attached to each
side of the shoot. To effect the lifting of the shoot the pinion is engaged with
the shaft by a clutch. This shaft is also provided with a ratchet wheel to retain
the weight of the shoot at any height. I also provide in connection with this
staith a spout for conducting the screenings from the shoot to railway trucks on a
siding beneath. This spout is made of sheet iron and is suspended by a chain or
chains to the shoot.
One of the chief difficulties to be encountered in the construction of a moveable
staith is that of transferring the wagons from the sidings to the staith it being
impossible to have fixed connections of sidings as in the case of fixed staiths.
This difficulty is overcome by my travelling carriage for conducting the wagons
from the sidings to the staith at whatever point the "staith may be required to
work and as this may also be done in other ways I proceed to describe them.
The staith may be constructed in the ordinary way except that all its parts
niust work above ground to admit of its travelling along the quay, or it may be
constructed as the staith herein before 'described with the exception that the
hydraulic cylinder for lifting the cradle is placed at the side instead of the back
und with exception that the cradle upon which the wagon is lifted and tipped is
attached to the lifting frames instead of being part of the travelling carriage.
The wagon is run into the staith through the space in the rectangular lifting
frame. This form of staith may be used in connection with my travelling carriage

page_text: the said carriage being stopped against the staith so that the rails on the carriage
exactly meet those on the cradle; the wagon is then run off into the staith.
The object of the present Invention however is to protect the working of a
moveable staith in connection with sidings the transfer of the wagons being
effected by a length of siding mounted upon girders in the form of a bridge being
connected at one end to the staith and at the other end to the sidings and so
arranged as to admit of a certain range at which the staith may work being at all
times in direct connection with the sidings so that the wagon may by passing.
over the turntables, one at each end of the swing bridge, be enabled to first pass
onto the bridge and afterwards by the other turntable to pass off the bridge into
the staith at whatever angle the bridge may have to the staith. One end of
the bridge is pivotted on a carriage and the other on the staith. These same pivots
being the points upon which the turntables turn. The carriage carrying the end
of the bridge is free to travel on rails at right angles: to those upon which the
staith runs.
It will be understood that the staith being in its central position the
carriage will carry the end of the bridge nearest to the end of the sidings and at
other positions of the staith there will be a more or less gap. between the end of
the carriage and the end of the siding. I provide an arrangement of sliding and
overhanging rails to span this gap; this is done by running the wagon for a short
distance on the flanges of its wheels. The connection of hydraulic power is made
by pipes taken from the end of the siding to the bridge by means of a telescope
arrangement and swing joints to the staith. This staith may either be moved by
the action of the lift carrying with it the end of the bridge or by racks laid
alongside the rails upon which the staith runs, there being a pinion geared in each
rack and worked together by the action of one shaft this shaft being driven by
the action of an hydraulic engine. The hydraulic engine may be otherwise geared
with the wheels upon which the staith runs. By an arrangement of clutches and
wheels, the pinions may be made to turn in either direction and effect the moving
of the staith to any position required. This arrangement of swing bridge may be
u-ed alike for high and low level railways or whether the staiths be worked by
hydraulic or by balance weight. The bridge may also be worked in connection
with a high level stageing with my travelling frame carrying the shoot and
appliances for tipping the wagon and lowering the material into the ship.
The travelling frame in this case is provided with a floor and so arranged that
the wagon may enter the back instead of the side. This floor may have in it a
tilting platform for tipping the wagon.
The object of this patent is also to protect an arrangement of turntables on high
level stageing along the quay so that the wagon may be put onto any one of these
turntables and be tipped by means of my travelling frame carrying the shoot and
appliances for lowering the coal from the mouth of the shoot into the ship. The
turntables may in this case be fitted with the tilting platforms pivotted at one end
in the usual way for tipping the wagon.
These turntables may also be arranged at the back of the travelling frame for
the purpose of turning the wagon onto a floor being a part of the travelling frame.

page_text: Improvements in Staiths and Apparatus in Connection therewith
for the more Rapid Shipment of Coal, Minerals, and other
like Materials from Railway Wagons.
I SAMUEL BUTLER, of N° 127 Bute Road, Cardiff, in the County of Glamorgan,
Engineer, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN STAITHE AND APPARATUS IN CONNECTION THEREWITH FOR THE MORE RAPID
SHIPMENT OF COAL, MINERALS, AND OTHER LIKE MATERIALS, FROM RAILWAY
WAGONS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
"
This Invention has reference to prior Improvements in staiths and appartus in
connection therewith for the more rapid chipment of coal and other material from
Hailway wagons, for which Letters Patent were granted to me-bearing date
respectively, July 21st A.D. 1884, N° 10,414, August 7th A.D. 1884 N° 11,032,
September 12th A.D. 1884, N° 12,330.
The first part of my present Invention relates to the first of the above mentioned
Patents and especially to the following paragraph. "Instead of running the wagon
"off the travelling carriage into the staith, the travelling carriage may be run inte
"the staith with the wagon upon it and the whole raised or lowered to the point
"of-tipping" and the object thereof is to construet-movable-staiths to receive the
travelling carriage and lift the same with the wagon upon it to any required height
for tipping.
And in order that my Invention may be more fully understood I hereto annex
sheets of Drawings-illustrative thereof.
Figure 1 is a back elevation, Figure 2 a side elevation and Figures 3 and 4
detached views of staith and apparatus connected therewith.
The carriage is shown with the wagon upon it proceeding towards the staith.
This carriage is made in two parts, the upper portion A forming the cradle-which
is taken up in the lift, and the lower portion B forming the body of the earriage
mounted on wheels and remaining on the rails. The carriage is moved by two
hydraulie cylinders C. C. geared by racks and pinions with a short shaft-upon
which are keyed two pulleys D. A wire rope is wound on each pulley in opposite
directions and attached thereto. The one rope leading over the pulley E and the
other over-the-pulley F and having their ends attached to the carriage. By
actuating the cylinders alternately the carriage is made to travel in either
direction as required for conveyance of the loaded wagon from the sideing to the
staith and returning it empty. The staith is constructed in the ordinary way,
being a framework of iron well braced together and mounted on wheels G. G'-g-g₁
and running on parallel rails H. h
The four corner main uprights I, I'-i, i'-form guides. A rectangular lifting
frame Jis worked, in the guides I. I' and another rectangular lifting frame is
worked in the guides i. i':
These lifting frames are provided with feet K, K. projecting (for the purpose of
lifting the cradle A of the body of the carriage. The lifting is effected by a
hydraulic cylinder I having eight chains; their ends being fastened at the point M
and running over the top and bottom pulleys N-n, theneo-over the pulley 0 on

page_text: the top of the staith, four of the chains going down and attaching to the one
lifting frame at P and the remaining four chains passing over the pulley Q and
thence downwards and attaching to the other lifting frame at R. The wagon-is
tipped in the ordinary way as represented at S by a tilting platform being a part
of the cradle A pivotted in front and lifted at the back by attaching a chain-at-T,
which is actuated by the hydraulic cylinder U.
Figure 2 represents the lifting of the lovers by a chain attached to the bottom-of
the box for regulating the discharge of the sheet when it may not be necessary to
lower the machine into the ship.
The second part of my Invention relates to Patent No-11,032, Date: August 7th
A.D. 1284, in which are described appliances for working a box by balance weights
and also appliances for opening and closing the mouth of the shoot. The box may
be worked by a hydraulic cylinder combined with a balance-weight in the following
manner:
The double jibrojecting over the shoot and also the weights on the ends of the
levers for closing the month of the shoot may be dispensed with, the same effect
being produced by the weight of the box and its contents by running-the-chains
by which it is suspended over pulleys at C, on the ends of the levers D there being
one lever on each side of the shoot. In order to provide against the box running
wild by careless working of the brakes, I provide for lifting and lowering it by a
hydraulic cylinder F. There are two chains having their ends-fastened at G and
thence passing parallel to each other twice over the top and bottom pulleys J.-j
thence-over like pulleys at K and L-down-over corresponding pulleys-at-C, then
being attached to the cross-bar M which in its turn is attached to the doors at opposite
sides of the box, as represented at N. The cross bar M is made to lift the levers for
the purpose of lowering the lip E, thus opening the mouth of the shoot: To each
side of the box is attached a chain which also passes over-pulleys at C, thence
upwards over pulleys at L again over pulleys at O and under pulleys at P. p. in a
balance weight and coming up are attached at Q. 7. The object of this balance
weight is to take up the slack of the chains when the box rises and give it out
when the box descends as well as to stop the descent of the box at any required
depth which it does by coming against the sliding stops R. r. which may be fixed
at any-height by tongues engaging in racks S. s. In lowering and lifting, the
weight of the box is taken up by the chains from the hydraulic cylinder F which are
attached to the doors.
In-discharging, the weight is taken up by the other chains attached to the-box
which releases the door chains permitting the contents to force the doors-o; en-nnd
discharge itself into the ship as represented at T. This came arrangement-of
working the box by the combined nation of the hydraulic eylinder-and-balance
weight may be seen fitted to the low level staith, Figures 2 and 4, there-being
three chains in this ease instead of four to facilitate the use of an ordinar Swing
jib Y. The two outside-chains A' B' being attached to the cross bar (which in
its-turn-is-attached to the box. The centre chain 12-is-attached-to-the cross bur E
which in its turn is attached from its two-ends to the doors. The chains A and B'
pass over pulleys at F' G' and H², and are attached to the balance-weight
at I. A large link J' is provided-in-each-of-these two chains so that they will
not pass the adjustable stop K², which in this case slides horizontally-and-is
capable of adjustment to any point on a rack extending the whole width of the
staith-from-back to front. The centre chain D2 likewise passes over pulleys
and G' after which it passes over the top and bottom pulley of the hydraulic
eylinder L'.
The nation of this hydraulic erlinder in lifting and lowering the box as well as
the action of the stop K³ in arresting the descent of the box at any required de-th
enabling the doors to open by the release of the door chains, has been fully
described in reference to Figure 6.
It has been customary hitherto in the working of staith shoots to check the con!
in the shoot by a wing board, hinged on one side of the shoot having its outer-end

page_text: held across the shoot. This arrangement however is somewhat imperfeet in its
netion. I effect the same result by lifting up a portion of the bottom of the shoot,
preferably the end, about one fourth of its length. This rising portion, which I call
the lip, is represented at M². It may be the bottom only or the corresponding
sides may be also made to rise.
I employ the following arrangement for keeping up the lip against the pressure
material in the shoot by weights applied to-the-ends of chaing at N³. There are
preferably two chains with a weight on each being parallel to each other, and
passing over pulleys at O² and P2, thence-downwards-and-attaching to the ends of
levers Q on each side of the shoot.
These levers are fixed on pivots at R² attached by brackets to the shoot, and are
long enough to stand beyond the end of the shoot to form a guide for the three
chains working the box as well as to provide means for lowering the lip by the
action of the box as it comes up to the sheet to be filled. This is effected-by-the
eross bar coming in contact with the said levers as shewn in the drawing.
Referring again to Figures 5 and 6, the hydraulic cylinder U is made to serve
the double purpose of tipping the wagon and raising the end of the shoot clear of
the ship.
This is effected by a rack on the top of the ram engaging in a inion running
loose on the end of a-shaft-V, which has keyed upon it-two drums for winding in
the chains passing over pulleys at L, and attached to each side of the shoot at W.
To effect the lifting of the shoot, the-pinion is engaged with the shaft V by means
of a clutch.
The shaft V is also provided with a ratchet wheel to retain the weight of the
shoot at any height.
I also provide in connection with this stuith, a spout for conducting the
sereenings from the shoot to Railway trucks on a siding beneath, as represented
at X. This spout is made of sheet iron and is suspended by a chain or chains to
the-shoot.
One of the chief difficulties to be encountered in the construction of a movable
staith is that of transferring the wagons from the sidings to the staith, it being
impracticable to have any fixed connections of sidings, as is the case with fixed
staiths This difficulty is overcome by my travelling enrriage swing bridge for
conducting the wagons from the sidings to the staith at whatever point the staiths
may be required to work, and as this may also be done in another the way I now
describe it.
Figure 77 is an elevation and Figure 82 a plan view-The transfer of the wagon
is effected over a length of siding mounted upon girders in the form of a bridge,
being connected at one end to the staith and at the other end to the sidings, and
so arranged as to admit of a certain range at which the staith may work,
remaining at all times in direct connection with the sidings so that the wagon
may, by passing over the turntables, (one at each end of the swing bridge), be
enabled to first pass onto the bridge and afterwards to pass off the bridge into the
staith at whatever angle the siding may have to the bridge or whatever angle the
bridge may have to the staith.
The bridge has two pivots A and B. The pivot A is mounted on a carriage
travelling on rails laid at right angles to the quay. The pivot B is mounted on
the staith and is carried by it to any part of its range.
.
As the staith moves from its central position carrying one end of the bridge
with it, the other end of the bridge is drawn forward and a gap C is formed
between that end of the bridge and the sidings. In order to retain the connection
at this point, the rails may be made to slide past each other in either of the two
ways, as represented in sections Figures 3 and 10 4. The pipe for conveying
hydraulic power passes through the pivot A then under the bridge and through
the pivot B to the staith.
The construction of the Swing Bridge may be better seen on reference to:
Figure 5,-plan view, Figure 14-8 end to end section Figure 126 cross section

page_text: through A. B. Figure 15 9 cross section through C. D. The bridge is constructed
of two main girders G. H. connected by cross girders at the two pivots I. J. and
mounted on rollers which travel on paths around the pivots. The pivot I is
mounted on the carriage K, and the pivot J is mounted on the staith. The
hydraulic pipe may be seen telescoped beneath the carriage then passing up through
the pivot I when it passes along under the bridge and through the pivot J to
the staith.
The foregoing arrangement of swing bridge may be used for conveying the
wagons to and from any form of movable shipping appliances.
Figures 71 and 82 shew the swing bridge fitted to a low level staith.
The wagon is run off the bridge into the cradle or lift and raised by the nction
of one hydraulic cylinder in the same manner as described in reference to Figures 1
and 2 except that the cylinder is placed at the side of the staith instead of
the back.
The ropes or chains from the cylinder pass over the pulley D from which point
half of their number go down and are attached to one side of the cradle, and the
others-pass over the pulley E and thence downwards and are attached to the other
side of the eradle. The tipping is effected by a chain from the cylinder F which
has to be attached to the tilting platform after each ascent of the cradle. This
staith is mounted on wheels to run on three parallel rails G. H. I.
The Swing Bridge may also be applied to a balance Staith for shipment of coal
from high level railways as shewn in Figure 16 10.
In this case the mechanism for working the staith may be precisely the same as
the balance staiths usually worked except that it is mounted on wheels to travel
on the parallel rails A. B. C.-One end of the swing bridge rests on the staith at D,
and the other on the carriage at E..
In cases where it may not be convenient to work the swing bridge, I use the
travelling carriage or traverse-table fer-conducting the wagons from the sidings to
the stuith.
To make this clear I give plans of ships loading by both arrangements.
Figure 17 11 is a plan of a ship being loaded by three staiths. The centre one
may be an ordinary fixed staith and the outside staiths A. B. may be movable
staiths of any description high or low level, arranged to travel to a certain range
in either direction from their central position, the connection with the sidings being
retained by the Swing Bridges ('. 1).
Figure 18 is a plan of a ship being loaded by three staiths. The centre one may
be an ordinary fixed staith, and the outside staiths A.-B. may be movable staiths
of any description, high or low level, arranged to travel to a certain range, the
connection with the sidings being retained by my travelling earringes or traverse-
tables C. D. These earringes may be worked by hydraulic power as shewn, or by
any other power or means. The carriage is brought opposite the sidings and the
wagon being run on it is moved to the back of the staith when the wagon is run
off into the staith.
To-move-Balance Staiths I prefer to use a hydraulic winch on the staith
arranged with a double drum, the chain on one drum being wound in the opposite
direction to the chain on the other drum, and leading in opposite directions are
attached at opposite ends of the staiths' path. The moving of the staith may
also be effected by a hydraulic Engine being geared with the wheels upon which
the staith travels or by a pinion engaging in a rack extending the whole length of
the staiths' path.
Having thus particularly described and ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried into
effect, I desire it to be understood that what I claim, is :-
1. The use of a movable staith constructed for lifting the travelling carriage or
portion thereof, substantially as herein described.
