IMPROVEMENTS IN HYDRAULIC TIPPING APPARATUS FOR DISCHARGING TRUCKS
INTO BARGES OR SHIPS." [A communication from abroad by the Compagnie des
Mines de Houille de Bruay, of Bruay, in the French Empire.]
According to the present Invention a platform is supported at the level of the
ground by the plunger of a bydraulic ram in a pit beneath, and is provided with
rails upon which are run the trucks to be discharged, the rails being so placed that
the truck presents its side to the side of the wharf or embankment alongside of
which is the barge or ship to receive the load. At this side the platform is turned
up at right angles, and at some distance from the ground the vertical part is pivotted
to two standards fixed on the ground, so that when the platform is raised by the
hydraulic ram it turns upon the said pivots so as to tilt up the truck to any
desired angle, the ram being connected to the platform by hinged links to allow of the
angular motion of the latter.
On the top of the vertical part of the platform are screws having plates at their
ends, and rotated by.a worm and worm wheel so as to bring the said plates to bear
firmly against the side of the truck and thus prevent it from tilting off the rails
when raised into the inclined position. To the top of such vertical side of the plat
form is also hinged the upper end of part of the shoot for conveying the contents of
the truck into the vessel, the lower end of such part of the shoot resting upon the

IMPROVEMENTS IN HYDRAULIC TIPPING APPARATUS FOR DISCHARGING TRUCKS INTO
BARGES OR SHIPS." A communication from abroad by the Compagnie des Mines
de Houille de Bruay, of Bruay, in the French Empire.
According to the present Invention platform is supported at the level of the
ground by the plunger of a hydraulic ram in a pit beneath, and is provided with
rails upon which are run the trucks to be discharged, the rails being so placed that the
truck presents its side to the side of the wharf or embankment alongside of which
is the barge or ship to receive the load. At this side the platform is turned up at
right angles, and at some distance from the ground the vertical part is pivotted to
two standards fixed on the ground, so that when the platform is raised by the
hydraulic ram it turns upon the said pivots so as to tilt up the truck to any
desired angle, the ram being connected to the platform by hinged links to allow of
the angular motion of the latter.
On the top of the vertical part of the platform are screws having plates at their
ends and rotated by a worm and worm wheel so as to bring the said plates to bear
firmly against the side of the truck and thus prevent it from tilting off the rails
when raised into the inclined position. To the top of such vertical side of the
platform is also hinged the upper end of part of the shoot for conveying the
contents of the truck into the vessel, the lower end of such part of the shoot resting
upon the upper end of the shoot proper, which is pivotted at an intermediate point
of its length to the foundation at the edge of the wharf, so that the greater
portion thereof overhangs the river or waterway so as to enter the hold of the
.vessel..
The lower end of the shoot is formed of a separate piece pivotted at its middle to
overhanging arms on the upper part of the shoot, so that such lower end may by
means of a lever arm fixed to it and actuated by a chain and worm wheel be made
to assume a variety of positions relative to the upper part in order to direct the
materials passing down to any desired part of the vessel.

page_text: The upper end of the main shoot carries pinions in gear with toothed quadrants
fixed on the wharf, so that by turning such pinions by suitable gearing the shoot may
be made to assume any desired inclination or be raised into a horizontal position
over the water when not in use so as not to interfere with the traffic.
Figs. 1 and 2 represent transverse sections of apparatus according to this Invention,
the one shewing the truck on the level platform, and the other shewing the truck
raised for tipping; Fig. 3 is a side view; and Fig. 4, a plan.
A is the platform with lengths of rail on it in line with the rails running parallel
to the quay wall. The transverse bars of the platform are bent upwards, and have
trunnions at B working in bearings in supporting frames C. Above the trunnions B
are sliding blocks D worked by serews and worm gearing, so as to press against the
side of the truck and prevent it from shifting off the rails when it is tilted. Under
the platform is the hydraulic cylinder E, the ram of which is connected by the
jointed link F to the platform A. The shoot G has at its lower end a rocking shoot
H, which by means of a chain attached to a barrel worked by worin gear at I, can be
turned into different attitudes, as shewn in Figs. 1 and 2 respectively, so as to direct
the materials descending by the shoot to the one side or other of the vessel. A short
shoot J jointed to the platform rests on the upper part of the shoot G, being free to
move to and fro thereon as the platform is tilted. The shoot G rests on a horizontal
axis mounted in bearings close to the edge of the quay, on which axis it can be caused
to rock by a winch motion K, so that when it is not in use it can be raised to a
level attitude clear of the barge or vessel; and when in use it can be set at a suitable
inclination. In operating with this apparatus the loaded truck being run on to
the platform A, and the blocks D being screwed up against it, the side doors of the
truck are opened, and the hydraulic cock or valve L is turned so as to admit water
under pressure from pumps or an accumulator to the cylinder E. The platform and
truck being thus slowly raised and tilted, the contents of the truck run down the
shoot to the vessel.
When the truck is emptied the cock or valve L is turned so as to cut off the supply
of water under pressure and open the discharge from the cylinder E, whereupon
the platform and truck descend again to the horizontal position. The blocks D are
then drawn back, leaving the truck free to be run off the platform.
c
This apparatus, which is of moderate cost, has the advantage of involving no
alteration in the rolling stock; and the movement imparted by the hydraulic cylinder
being slow, the contents of the truck are discharged in a moderate stream, and not
in a mass suddenly projected, as when steam power is used to effect the tipping
action.
Having thus described the nature of this Invention and in what manner the same
is to be performed, as communicated to me by my foreign correspondents, I claim,
the use of hydraulic tipping apparatus constructed and operating substantially as
herein described.
In witness whereof, I, the said Charles Denton Abel, have hereunto set my
hand and seal, this Twenty-seventh day of February, in the year of our
Lord One thousand eight hundred and seventy-eight
