from Trucks.
I, GEORGE CARRINGTON FOWLER, of Cliff Houses, Cinder Hill, in the Town and
County of Nottingham, do hereby declare the nature of this. invention to be
as follows:-
In apparatus constructed according to my invention the truck to be emptied
is run on to a platform supported between two wheels or frames mounted on a
horizontal shaft at a distance apart somewhat greater than the length of the
truck. The platform is at this time below the level of the shaft and on one
side of it-the truck is run on to the platform in a line parallel with the shaft
At this time the
and passes through one of the wheels or frames to do so..
wheels are prevented from turning by brakes applied to them-preferably by
brake straps passing partly around them to which weights are attached which
normally keep the brakes applied. When a truck has been run on to the platform
projections on the sides of the truck come below bars fixed to the two wheels or
frames and the truck is so held to the platform when the platform is subse-
quently inverted. By means of a brake lever acting to raise the weights which
apply the brakes the brakes can be released the weight of the loaded truck then
turns the wheels and the truck is first turned over on to its side and then com-
pletely inverted so discharging the coal or material from it. When a complete
half turn of the wheels has been so made they are stopped by the brakes, a second
platform carried by the wheels on the opposite side of the shaft to the first plat-
form is then in position for another loaded truck to be run on to it. When the
brakes are again released the contents of this second truck are similarly dis-
charged whilst at the same time the first truck is carried back into position ready
to be pushed off from the platform which carries it by the next loaded truck and
so on continuously.
As each loaded truck is being turned over in the manner above described the
coal or material rolls out from it, first on to a plate fixed between the wheels at
a short distance from the outer side of the truck. As the turning over of the
truck continues this plate which may at first have been vertical is brought into
a horizontal and then into a downwardly inclining position and the material
rolls along it until stopped by a fixed shoot situated below the wheels-the
material then slides gradually down the shoot, the plate keeping it from being
discharged with a rush so that the material is discharged gently into the shoot.

I, GEORGE CARRINGTON FOWLER, of Cliff Houses, Cinder Hill, in the Town and
County of Nottingham, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement; --
In apparatus constructed according to my invention the truck to be emptied
is run on to a platform supported between two wheels or frames mounted on a
horizontal shaft at a distance apart somewhat greater than the length of the
truck. The platform is at this time below the level of the shaft and on one
side of it the truck is run on to the platform in a line parallel with the shaft
and passes through one of the wheels or frames to do so. At this time the
wheels are prevented from turning by brakes applied to them-preferably by
brake straps passing partly around them to which weights are attached which
normally keep the brakes applied. When a truck has been run on to the platform
projections on the sides of the truck come below bars fixed to the two wheels or
frames and the truck is so held to the platform when the platform is subse-
quently inverted. By means of a brake lever acting to raise the weights which
apply the brakes the brakes can be released the weight of the loaded truck then
turns the wheels and the truck is first turned over on to its side and then com-
pletely inverted so discharging the coal or material from it. When a complete
half turn of the wheels has been so made they are stopped by the brakes, a second
platform carried by the wheels on the opposite side of the shaft to the first plat-
form is then in position for another loaded truck to be run on to it. When the
brakes are again released the contents of this second truck are similarly dis-
charged whilst at the same time the first truck is carried back into position ready
to be pushed off from the platform which carries it by the next loaded truck and
so on continuously.
As each loaded truck is being turned over in the manner above described the
coal or material rolls out from it, first on to a plate fixed between the wheels at
a short distance from the outer side of the truck. As the turning over of the
truck continues this plate which may at first have been vertical is brought into
a horizontal and then into a downwardly inclining position and the material
rolls along it until stopped by a fixed shoot situated below the wheels-the
material then slides gradually down the shoot, the plate keeping it from being
discharged with a rush so that the material is discharged gently into the shoot.
The drawing annexed shows various views of an apparatus constructed as above
described.
Figure 1 is an end view, Figure 2 a plan, and Figure 3 a side view. Figure 4
is a vertical section through the line A B Figure 2 except that the wheels are in
a position intermediate between their two stationary positions and illustrates the
way in which the mineral is deposited from a truck on to the fixed shoot.
A A are the wheels fixed on a shaft B at a distance apart somewhat greater
than the length of a truck. CC are two pairs of rails extending across from one
wheel A to the other-one pair at one side of the axis and the other on the
opposite side and the two pairs in different planes so that when one pair is in a
horizontal plane below the axis the other pair is in a horizontal plane at a cor-
responding height above the axis. DD are break bands passing around the
wheels A, E a weight hung on to the end of the bands to lock the wheels and
restrain them from turning. FF are trucks and F projections on opposite

page_text: sides of the trucks. G G are bars fixed to the wheels below which the projec-
tions F pass when a loaded truck is run on to one of the pairs of rails and which
serve to hold the truck up to the rails when the truck is subsequently inverted.
H is a lever coupled by a link H with a lever arm I¹ fast on an axis I on which
are shorter arms 12 coupled to the moveable ends of the brake straps so that by
shifting the handle of the lever H in the direction shewn by the arrow in
Figure 1 the weights E may be raised and the brakes released. K is a hook
catch jointed to the lever H which when the lever has been turned into a position
to release the brakes catches over the stop L and keeps the brakes released.
stop L is carried by an arm extending from an axis M. A projection N extend-
ing downwards from another arm on this axis normally keeps the stop I, in
acting position. P P are two pegs standing out from the side of one of the
wheels A. When the brakes are held off and the wheels A turn they continue
to turn until one of the pegs comes against the end of the arm and thereby
depresses the stop L until it is free from the catch K the weight E is allowed
to descend and at once applies the brakes.
The
R is a fixed shoot down which the coals are to be delivered and S S are plates
fixed to the wheels to support the coal or mineral as it passes from the trucks on
to the shoot.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:—
1. Apparatus for tipping coal or other material from a truck so constructed
that the loaded truck to be emptied can be run on to a frame capable of revolv-
ing and the weight of the loaded truck can afterwards serve to turn the frame
and thereby invert the truck and discharge its contents and in which the emptied
truck is afterwards brought back to its original position by a further movement
of the revolving frame.
2. In apparatus for tipping coal or other material from trucks the combination
of a wheel or frame mounted on a horizontal axis and carrying two platforms on
opposite sides of the axis, a brake to lock the wheel or frame and restrain it
from turning when the two platforms are in horizontal positions and means for
holding the trucks to the platforms, so that when a loaded truck has been run
on to one platform and the brake released the wheel or frame is turned by the
weight of the loaded truck and continues to turn until when it has made a half
turn and the truck has been inverted it may be again arrested by the brake.
3. In apparatus for tipping coal or other material from trucks the combina-
tion of a wheel or frame mounted on a horizontal axis and carrying two platforms
on opposite sides of the axis in different planes, openings in the wheels or ends
of the frame to allow of trucks being run on to the platforms in a direction
parallel with the axis, a brake to lock the wheel or frame and prevent it from
turning when the platforms are in a horizontal position and means for holding
the trucks to the platforms when the trucks are inverted.
4. Apparatus for tipping coal or other material from trucks constructed sub-
stantially as herein before described and illustrated in the drawing annexed.
