Engineer do hereby declare the nature of this invention to be as follows:-
My Invention is for improvements in loading Coal, Coke, ore and other materials
into waggons or other vehicles or receptacles and is accomplished in the following
manner.
The necessary mechanism is pivoted and placed upon a bogie, carriage or loco-
motive which may be self propelled by suitable engines and power; or may be
moved from place to place by other means. To perform the required operations
there is a charging cylinder, piston, piston rod and guides; and on the end of the
piston rod there is a shovel or grid having forks of suitable size and mesh, placed
horizontally. This cylinder is hinged at some suitable point so as to allow a ver-
tical oscillatory motion as the piston rod moves outwards or inwards. And towards
the end of the outward stroke the guides have a twist or rifle so as to tilt the
charge from the grid. Toward the end of the piston rod at a suitable distance
from the grid or shovel there is a pin and eye or other attachment which is con-
nected to a rod or bar working in a vertical or somewhat vertical direction between
suitable guides, and the opposite end of this bar is connected by a chain, rope or
other means to a piston rod attached to a piston working in a suitable lifting
oylinder. These aforementioned cylinders have suitable admission, exhaust and
other necessary valves worked through links cranks levers &c by means of suitable
handles levers or screws. The cylinders are driven or propelled by steam, hydraulic
or other motive power; and the various parts of the machine
may be of any suitable
material, design or pattern.
The mode of working is as follows-The attendant by means of hand levers &c
operates on the valves of the hinged cylinder causing the piston and piston rod
with the grid to move forward and so the grid thus enters the material to be
removed and takes a charge. A pawl or catch may he arranged to limit the extent
of this part of the stroke.
As the grid advances or as soon as the charge is taken the lifting oylinder by
similar or other suitable mechanism is brought into action lifting through a
chain &c the piston rod of the charging cylinder with its grid and charge working
on the hinge of the charging or hinged or oscillating cylinder. As soon as the
grid has thus attained a proper elevation the apparatus is alued by being turned
on a pivot by some suitable mechanism and motive power. And when slued into
the desired position the pawls are withdrawn and the stroke of the charging
cylinder is continued and completed. The twisted or rifled guides turning tho
grid or shovel on its axis on the piston rod from a horizontal position through an
angle of about 90°. or whatever is necessary. The charge on the grid is thus
tilted and discharged and the apparatus is then brought back to its normal position
ready to take a fresh charge. These operations are repeated as often as they may
be required.

page_text: The charging cylinder instead of being hinged may be fixed, and the rod carry-
ing the grid may be hinged on the end of the piston rod. This apparatus can be
applied either specially or adapted to any existing steam, hydraulic or other
огаде.
I GEORGE NIXON of Victoria Garesfield Colliery Lintz Green County Durham
Engineer do hereby declare the nature of this 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 is for improvements in loading Coal Coke Om and other
materials into waggons or other vehicles or receptacle and is accomplished in the
following manner.
The necessary mechanism is attached or fixed to the rotating part of framework
of the crane which is pivoted upon a bogie, carriage, or locomotive which may be
self propelled by suitable engines and power: or it may be moved from place to
place by other means.
To perform the required operations there is a charging cylinder, piston, piston
rod and guides; and on the end of the piston rod there is a shovel or grid having
suitable dimensions and mesh placed horizontally.
This cylinder is hinged at some suitable point. so as to allow a vertical oscil-
latory motion as the piston rod moves outwards or inwards and towards the end of
the outward stroke the piston rod guides have a twist or rifle action so that after
the grid has taken its charge it may by a prolongation of the outward movement
be tilted at any, desired movement or the piston rod and cylinder may be in a fixed
plane and the vertical oscillatory movement. given from a rod hinged on the
piston rod.
Toward the end of the piston rod or oscillatory rod at a suitable distance from
the grid or shovel there is a pin and eye or other attachment or guide rollers may
be placed on the vertical bar.
This vertical bar having guide rollers on it or being attached to the oscillating
rod works in a vertical or somewhat vertical direction and the opposite end of this
bar is connected by a chain, wire rope or other means to a piston rod attached to
a piston working in a suitable lifting cylinder.
The vertical bar works in a guide or guides, and when this bar has the guide
rollers on the end the guides for the bar should bo firmly attached to the jib of
tho crane or other points. When the vertical bar is attached by a pin or otherwise
to the oscillating bar or rod, the guides for the vertical bar would then be hinged
only at the end of the jib.
There may be a pawl or ratchet to retain the charging cylinder in any desired
position.
The aforementioned cylinders have suitable admission, exhaust, and other
necessary valves worked through links oranks, lovers and the like by. means of
suitable handles. levers or screws.
The cylinders are driven or propelled by steam, hydraulic or other motivo
power.
The grids may be changed for different. material.
In the drawings No 1, fig 1 is a side elevation of the crane and mechanism shew-
ing the load about mid position before it has been tilted.

page_text: No 2, fig 2 is a part plan of the same in which.-
A is the handle and A' the actuating valves for the oscillating or charging
cylinder B in which works the piston and piston rod C at the end of which the
grid D is attached.
E is the handle and E' the valve for actuating the lifting cylinder F. G is its
piston rod H is the chain connecting the piston rod with the lifting bar I.
JJ are the rollers on the end of the lifting bar I. K is the guide for lifting bar I.
Lis the jib of the crane M is the platform or framing pivoted on the bogic or travel-
ling carriage N and P is the pawl or catch for holding at any point the grid D
and rod C. Q is the hand lever for putting the pawl Pinto gear. R is the guide
with a spiral at. its end.
The method of working is as follows.-The attendant by means of a band lever A
operates on a common D slide valve or other form of. valve A' which by suitable
pipes communicates with the charging cylinder B, causing the piston and piston
rod C with the grid D upon it to move forward.
The grid D thus enters the material to be removed and so takes ȧ charge.
The pawl P worked lever Q limits this part. of the stroke as. may be desired.
As the grid D advances and as. soon as the charge is taken the lifting cylinder E
is brought into action lifting through the bar I the piston rod C with the grid 1)
upon it.
As soon as it has attained a proper elevation and the crane is swung
round, the lifting cylinder B is again brought into action and finishes its stroke
the projections on the piston rod C on the spiral part. of the guide R gives the
necessary tilting movement to the grid D and so the load is discharged.
The crane is then swung round if necessary. the grid brought again to its normal
or charging position and the operations continued.
The parts may be of any desired or suitable material, design or arrangement
and the apparatus may be applied to existing cranes. or specially arranged for
new ones.
Having now particularly described and ascertained the nature of my said inven-
tion and in what. manner the same is to be performed I declare that what I claim
is.--
1st. The use of a cylinder having a piston rod with a twisting or spiral motion
derived from the guides, towards. the end of its stroke so as to tilt the material at
any suitable point after lifting or lowering it as described in the drawings and
Specification.
2ud. The general arrangement and. combination of parts substantially as set
forth in the drawings and. Specification.
