Steam Plough Works, Leeds, in the County of York, for an Invention of
"IMPROVEMENTS IN HAULING OR WINDING ENGINES AND WAGGONS."
PROVISIONAL SPECIFICATION left by the said David Greig and Richard
Holgate Shaw at the Office of the Commissioners of Patents on the 12th July
1881.
DAVID GREIG and RICHARD HOLGATE SHAW, both of the Steam Plough Works,
Leeds, in the County of York. "IMPROVEMENTS IN HAULING OR WINDING
ENGINES AND WAGGONS."
This Invention has for its object improvements in hauling or winding engines
and waggons.
We arrange a pair of winding drums and the coiling gear for each upon a
vertical axis beneath the boiler of the engine. The coiling cams are placed upon
the axis above and below the drums, that for the upper drum being above and
for the lower beneath. The cam, as is usual, actuates a coiling lever or arin
having its fulcrum at one end, and at the other guide rollers for the rope to
pass between.
The waggons are arranged to tip by the tractive power of the engine by which
they are drawn.
The body of the waggon is placed as low down as possible, and is jointed to the
bed over the wheels so that it can tip. The tipping is effected by a windlass
arrangement. Beneath the body there is a slide with a pulley at its lower end.
A rope attached at one end to the frame of the waggon is passed down beneath
this pulley, and is then taken up again to a barrel upon an axis carried in bearings
upon the frame. The axis can be turned by means of a wheel upon it and another
rope wound upon the wheel. The pull of the engine (or other traction) causes the
latter rope to be drawn off from the wheel, thereby turning the axis and causing

page_text: the rope attached to the body to be wound upon the barrel. So the slide is raised
beneath the body it raises the side of the body opposite to the joint, and so the
body is made to tip. The tipping may be made to take place to either side by
duplicating parts of the apparatus.
Or to effect the tipping to either side at pleasure we sometimes substitute an
hydraulic jack for the slides and parts operating upon them. This hydraulic jack
is placed beneath the body of the waggon, and is centrally jointed at its lower
end so that it can swing over, bringing the upper end or ram to act beneath the
body at the side opposite to the joint about which the tipping is required to take
place.

Office on the 11th January 1882.
DAVID GREIG and RICHARD HOLGATE SHAW, both of the Steam Plough Works,
Leeds, in the County of York. "IMPROVEMENTS IN HAULING OR WINDING
ENGINES AND WAGGONS."
This Invention has for its object improvements in hauling or winding engines
and waggons.
We arrange a pair of winding drums and the coiling gear for each upon a
vertical axis beneath the boiler of the engine. The coiling cams are placed upon
the axis above and below the drums, that for the upper drum being above and
for the lower beneath. The cam, as is usual, actuates a coiling lever or arm
having its fulcrum at one end, and at the other guide rollers for the rope to pass
between.
On Sheet No. 1 of the Drawings annexed Figure 1 is a side elevation of the
engine, and Figure 2 is a plan of the same.
a is the boiler with the engine on the top, and mounted on four travelling wheels.
The driving wheels are driven from the crank shaft by spur gear in the usual
manner, and as shewn by the dotted circles.
b is the drum stud or vertical axis on which the two drums are arranged; this
stud has a flat circular foot at its upper end, which is firmly bolted to a large
saddle bracket rivetted to the barrel of the boiler.
:
c, c, are the two winding drums which revolve loose on the vertical stud, and are
each driven by the pinions d, d, on the upright shaft c. f. f, are the two cams with
internal gear teeth, one for the top drum and one for the bottom drum. g, g, are
the two smaller wheels which gear into and drive the cams f. f; these two wheels
receive a rolling motion from the eccentrics h, h, the wheels being prevented from
revolving by the stop lever j, which is shewn on the top drum.
is the coiling lever with its pullies for the top drum. is the coiling lever
and pullies for the bottom drum. The levers may be turned to either side of the
engine.
Our Invention also relates to tipping waggons.
The waggons are arranged to tip by the tractive power of the engine by which
they are drawn. The body of the waggon is placed as low down as possible, and
is jointed to the bed over the wheels so that it can tip. The tipping is effected by
a windlass arrangement. The pull of the engine (or other traction) causes a rope
to be drawn off from a wheel or drum, thereby turning an axis and causing a rope
or chain attached to the body to be wound upon a barrel; it raises the side of
the body opposite to the joint, and so the body is made to tip. The tipping
may be made to take place to either side by duplicating parts of the apparatus.
On Sheet 2 of the Drawings Figure 1 is an end elevation, and Figure 2 is a side
elevation of a tipping wagon arranged according to this part of our Invention.
A is the buck or body of the wagon; it is carried in centres B on one or on both
sides of the frame.
The tipping apparatus consists of a simple windlass carried underneath the body
of the wagon, and mounted on the underframe; this windlass is worked by the
engine pulling on the rope C either direct or by the winding forward drum. The
motion communicated to the rope C causes the drum D to rotate, and drives the
shaft E and chain rollers F. The tipping chains G are coiled round the rollers F,
and are led up over pullies carried by frames standing up from the under frame.
The opposite ends of the tipping chains are attached to the body of the wagon

page_text: at H, where hooks are provided. When the chains G are wound on the rollers F
the body of wagon is lifted at H and centered at B, and caused to take the position
shewn in dotted lines.
The wagon can be tipped from either side, the direction of tipping depending on
which side of the body the end of the chain is coupled to. The parts which require
to be duplicated are the centres B and the hooks at H. The weight of the body
and load in it is distributed over the underframe of the wagon when travelling
on the road, the body resting directly on the underframe. When in the act of
tipping the weight is carried partly by the brackets B, B, and the lifting or tipping
chains.
According to another arrangement we effect the tipping to either side at pleasure
by an arrangement in which an hydraulic jack is used. This hydraulic jack is
placed beneath the body of the wagon, and is centrally jointed at its lower end
so that it can swing over, bringing the upper end or ram to act beneath the body
at the side opposite to the joint about which the tipping is required to take
place.
This construction of tipping wagon is shewn at Figures 3 and 4, Sheet 2.
Figure 3 is an end elevation partly in section, and Figure 4 is a sectional
elevation. A is the body of the wagon. B is the underframe on which the body
is carried, and which carries the hydraulic jack. C, C, are the two side brackets
which carry the centre D for the hydraulic jack E. F is a casting fixed to the
wagon body, having a groove or channel in which the top of the jack is guided.
G is the handle for working the jack. H are the brackets fixed to the framing,
and which carry the centres on the body; these brackets are fixed on each side of
the framing, and are for carrying the body when being tipped.
The jack is hung from the framing of the wagon midway in its length and
breadth, and can be freely moved to either side of the wagon body, the position of
the jack depending upon which side the wagon is to be tipped.
Having thus described the nature of our said Invention and the manner of
performing the same, we would have it understood that we claim,—
First. The improved hauling engine, having a pair of winding drums and coiling
gear for the same upon a vertical stud or axis fixed beneath the boiler, the whole
being arranged substantially as described and illustrated on Sheet 1 of the
Drawings.
Second. The improved tipping waggon, in which the tipping is effected by a
windlass arrangement operated by the pull of the engine or other traction drawing
a rope from a wheel or drum, substantially as described and illustrated by Figures
1 and 2 on Sheet 2 of the Drawings.
Third. The improved tipping waggon, in which the tipping is effected by an
hydraulic jack carried upon the underframe beneath the body of the waggon,
substantially as described and illustrated by Figures 3 and 4 ou Sheet 2 of the
Drawings.
In witness whereof, I, the said David Greig, have hereunto set my hand and
seal, this Fifth day of January, in the year of our Lord One thousand
eight hundred and eighty two.
DAVID GREIG. (L.S.)
