PROVISIONAL SPECIFICATION.
Improvements in or connected with Hoppered Railway Wagons
for the Transport of Minerals.
I, GEORGE WATSON ETTENGER, of 20, Eastcheap, in the City of London,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention refers to that construction of railway and tramway wagons,
where the body is of hopper form, such as is commonly used for the transport
of minerals..
According to my invention the hopper wagon, with the ordinary form of hopper
having a falling door or doors at the base of the hopper body, is so arranged
that the load can be discharged through the bottom door or doors, either when the
hopper is in place, or when the said hopper is swung by a crane or other device away
from the wagon frame.
Thus by way of example, the hopper may be of truncated pyramidal form,
supported in a rectangular frame, the door or doors aforesaid forming a closure
to the lower, otherwise open, end, the said doors being controlled by suitable
devices, so that upon the door or doors being allowed to fall open, the contained
material will be delivered by gravity, between the rails beneath the frame of the
wagon. By such construction the body may be attached by suitable rings, lugs,
or the like, to the hooks of a crane, and be thereby lifted from the supporting
frame of the wagon.
Such a wagon body I generally provide with winding shaft, chains, ratchets, and
pawls, or equivalent devices, so arranged that the hopper body can be swung as
described, and the load discharged by a trip cord, or such like device, at the
desired point of delivery.
I arrange in combination with the sloping sides of the hopper, angle shaped
bearing bars attached to the frame, so that when hopper is lowered into position, it
will automatically right itself in position on the frame, and by reason of the shape
of such angle bars, lock itself in place against the shocks of shunting and transport.

Improvements in or connected with Hoppered Railway Wagons
for the Transport of Minerals.
I, GEORGE WATSON ETTENGER, of 20, Eastcheap, in the City of London,
Mechanical 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:
mafone
to that constmuation of

page_text: where the body is of hopper form, such as is commonly used for the transport
of minerals.
"
According to my invention, the hopper wagon, with the ordinary form of hopper,
having a falling door or doors at the base of the hopper body, is so arranged
that the load can be discharged through the bottom door or doors either when the
hopper is in place, or when the said hopper is swung, by a crane, or other device, away
from the wagon frame.
So that my invention may be better understood I will describe same by reference
to the accompanying drawings, of which Fig. 1 is a longitudinal vertical section
through the centre of the wagon. Fig. 2 is a cross section of half the wagon.
Fig. 3 is an end view of the other half of the wagon and Fig. 4 is a detached view
in side elevation shewing a ratchet and pawl arrangement adapted to be operated
-by a trip cord.
The hopper A may be of inverted truncated pyramidal form, supported in the
rectangular frame B, the hopper A being provided with a door D forming a
closure to the lower, otherwise open end, of the hopper A. The door D is attached
to one of the lower edges of the hopper A, by hinges C, the straps of which extend
across the door and form attachment pieces for chains E, which pass round the
barrel F of a winch. This winch is attached to one of the sloping sides of the
hopper, and is provided with a pawl G and a ratchet wheel so as to retain the winch
in any desired position.
?
Upon the pawl G being removed, the barrel of the winch is free to revolve, the
doors fall open and the contents of the hopper A are delivered by gravity between
the rails beneath the frame of the wagon.
The hopper A is provided with suitable rings or the like H, by which it may be
attached to the hooks of a crane and so lifted from the body B of the wagon, and
may be caused to deliver its contents in any desired place.
The frame B of the wagon may be constructed of iron of any suitable section or
of wood, but I prefer to use channel irons J, which are so arranged that a rectangular
opening sufficiently large to receive the lower portion of the hopper A, is provided
in the centre portion of same. Upon the upper surfaces of the channel bars J,
around the rectangular opening of the hopper A, I fix bearing pieces L of cast
malleable iron or other suitable material, and I preferably form the outer faces of
same at about right angles to the adjacent side of the hopper.
Attached rigidly to the sloping sides of the hopper A, are angle bars K arranged
to fit when the hopper is in position, upon the bearing pieces L, in such manner
that when the hopper A is lowered into the rectangular space provided in the body
of the wagon, the lower surface of the angle bars K will come in contact and rest
upon the surfaces of the bearing pieces L, and the hopper will automatically
upper
right itself in position on the frame, and will lock itself in place against the
shocks of shunting and transport. It will be readily understood that when the
hopper is lifted from the frame B, say by a crane, and held suspended that
the load can then be discharged by releasing the pawl, and also the discharge
can be effected in like manner when the hopper is in the position as shewn on the
drawings. A suitable construction or arrangement of pawl, adapted to be operated
when required by a trip cord is shewn at Fig. 4, where the pawl arm G is prolonged
and fitted with a ring G at its free end. A trip cord (not shewn in the drawing)
may be affixed to the ring G¹ and can be utilized to draw back the pawl G when
the hopper is held suspended. When the hopper A is in position on the body of
the carriage the ring G¹ of the pawl G can be turned over a pin G2 on the body B
and the pawl thereby prevented from becoming accidentally disengaged from the
ratchet wheel.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I
claim is:

page_text: base thereof, a door or doors to close the base of the hopper, mechanical means, such
as a winch and chain, for controlling the position of the doors, and means for
suspending the hopper from a crane or the like; in combination with a wagon body,
having an opening to receive the hopper, and supporting means on the hopper,
to engage or take against bearing pieces on the frame, to retain the hopper in
position, arranged and acting substantially as set forth.
2. The general arrangement and combination of parts, composing my improve-
ments in and connected with hoppered railway wagons, and whereby the hopper can
be readily removed or replaced, from or onto the carriage frame, is securely sup-
ported in position when on the frame, and whereby the contents of the hopper can
be discharged, either when the hopper is held suspended away from the wagon
frame, or when it is in situ thereon, all substantially as described with reference
to the accompanying drawings.
Dated this 12th day of November 1898.
