Automatic Raising Arrangement for Tipping Coal or other
Material into Storage Hoppers, or in Loading into Ships or
Barges from Wagons.
ROBERT MORTON HOWATT, Luhrig Coal and Ore Dressing Appliances Limited,
32 Victoria Street, Westminster, London, S.W. Mining Engineer, do hereby declare
the nature of this invention to be as follows:-
The invention relates to an arrangement of apparatus, employed for raising one
end of a wagon which may be loaded with coal or other material to such an angle
that the material is readily discharged into storage hoppers, ships or barges
economising time and labour in so doing.
Trucks or wagons containing material to be discharged are run over the lifting
arrangement and brought to rest when a screw raising arm which is driven by a
worm geared and actuated by shafting and driving pulleys catches the axle of the
wagon raising it easily and effectually for discharging. By reversing the motion of
the screw raising arm, the wagon is returned on its wheels, on the rails, to be replaced
by loaded wagons.

Automatic Raising Arrangement for Tipping Coal or other
Material into Storage Hoppers, or in Loading into Ships or
Barges from Wagons.
I ROBERT MORTON HOWATT of 32 Victoria Street, Westminster London,
Mining 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:-
This invention relates to means or apparatus by which railway and like trucks or
trolleys having no tilting appliances of their own can by a raising or lifting device
at one end have their contents discharged from the opposite end.
The tilting apparatus of my invention may be in pairs so that trucks to be emptied
can be run and be located over either end of a hopper or shoot into which the
material has to be discharged such as into storage hoppers, ship or barge shoots,
the invention being of value as regards economy of time in unloading and
effects a great reduction of labour, it is also applicable to coal trolleys or skeps on
wheels.
For the purpose of this invention, I run open rails over or next to a shoot or hopper
and at one end of the shoot or at one or both ends of the hopper, I arrange a
saddle or socket plate on the upper end of a screw rod which can be raised from a

page_text: cylinder, the rear axle of the truck fits in this socket plate, and as the raising takes
place the truck is tilted from that end for the contents to slide out from the
other.
My invention will be more particularly understood by an inspection of the annexed
drawings.
Figure 1 part sectional elevation of hopper with tilted truck over it.
Figure 2 plan of same with operating shaft over the mouth of the hopper.
Figure 3 plan of operating shaft at a distance from the elevating appliance.
Figure 4 section of screw lifter and gear support with sleeve on ball bearings to
reduce friction, the sleeve being rotatable and carrying one of the bevel pinions by
which the main screw is lifted.
A, A, side wall of hopper or shoot, B the slope thereof, C, C, rails laid on ground
like ordinary railway or contractors rails which for the purpose of my invention are
laid across the mouth of the hopper or shoot. D, D, are wells" or sunken tubes
between the rails C, C, and within which tube the lift screw E has free travel. F socket
or foundation bed with cover or cap G. H screw collar in gear with main or lift
screw E. This collar has say a six sided exterior or body for fitting a correspondingly
inwardly shaped head I of a bevel wheel J, the neck of which forms a sleeve K
extending downwardly to near the bottom of the foundation F, where it rests in a
cup L as a race for balls M, M, which run in the lower bearing N which is recessed
into the foundation F. P is the saddle or stirrup on the head of the screw E and
stands above the level of the rails when in a normal position and centrally with that
of the axle of any truck that may be brought over it, the saddle or stirrup P may be
pivoted on the head of the screw E for ready adjustment. P P are guide rods
depending from the saddle P and passing through the head G to prevent the screw
being turned.
The bevel wheel J is rotated by its gear Q from the shaft R from any prime mover
or it may be by a winch handle or otherwise and capable of being operated from one
side of the shoot only or from both sides if the appliance be so fitted as will be
gathered by the cross shaft S next or over the shoot as at Figure 2 or from a distance
as at Figure 8 where the throw in of a clutch T to the respective bevil wheel on the
cross shaft S will operate the screw E for raising and lowering it as desired.
The operation of tilting a truck will be completely understood by reference to
Figure 1 where by first loosening the end flap U of the truck and then tilting it, the
contents will slide out.
The double apparatus is capable of simultaneous action if two trucks be arranged
over the hopper or shoot.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The mechanical means hereinbefore described for lifting one end of a railway or
like truck for discharging the contents from the opposite or unlifted end substantially
as represented in the annexed drawings.
2. In apparatus for tilting railway and like trucks on rails the foundation F,
screw E, threaded collar H, bevil wheel J, sleeve K supported on ball bearings all as
arranged as and for the purposes described and substantially as shown at Figure 4 of
the annexed drawings.
