Improvements in Apparatus for Discharging Trucks without
Unhooking or Stopping Onward Motion.
I CHARLES MCALLISTER of Glenravel Glenravel Post Office County Antrim
Ireland Farmer 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 :-
DRAWING No. 1.
A to B. Graduated road from mineral depôt to place of emptying.
B. Place of emptying mineral into trow or shoot capable of carrying it into
ordinary railway truck or vessel in dock.
C. Section of road leading into revolving cylinder.
D. Continuation of road, leading up to mineral depôt.
E. Truck emptying into trow or shoot.
E. Empty truck entering revolving cylinder.
E. Empty truck emerging from cylinder having been put in upright position by
action of cylinder.
F. Place at which truck wheels become partly confined.
F to G. Part of the road where the wheels of the truck are confined between
an upper and lower rail during its passage.
H. Link tracked wheel round which an endless chain passes to which the truck
is joined by means of a hook attached thereto.
J. Revolving cylinder by means of which the trucks entering it in an inverted
position are placed in an upright position. This cylinder is long enough so as to
allow the truck to move on while it is half turned by which means the trucks are
placed upright leaving the cylinder and passing on to depot or place of filling.
The cylinder is turned by means of a crank and band marked respectively K and L.
The cylinder moves within circles, and to ensure its smooth and easy movement
metal plates are rivetted to each end.

page_text: through the cylinder without unhooking or stoping the trucks entering cylinder
and still connected to chain, the chain is under the cross bars of cylinder and
upright and passing along the axle the other eud where it is between the bars of
uprights and cylinder, the cylinder being half turned to alow the truck to pass on
to depot or place of filling the chain is now above the bars of cylinder and
uprights and between the bars of cylinder and uprighs where the truck entered.
I have a rough working modle which works successfuly. The above invention
when put in working order the trucks when connected to endless chain can be
propelled along the tracks by mean of steam engine or turbine wheel whatever
is most convenient.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is.
1st. The parts of Drawing No. 1 included between letters F and G and the
parts marked J, F and G include the part for which I claim protection. In it the
principal of double rails passing round the semicircular road and supporting
the truck at one part of the road in an upright position and when the truck passes
round the road it is supported in an inverted position by means of the outsid or
upper rail. The truck moving forward mouth downward enters the cylinder.
2nd. The part marked J being a cylinder revolving upon an axle and having
double rails an upper and a lower similar to those on semicircular part of road.
As soon as the truck enters the cylinder it is turned by a man at crank and lever K
acting on cylinder by means of band L and for these I claim protection.
Dated this 18th day of April 1893.
