Improvements in Waggons suitable for the Conveyance by Railway
or Tramway of Coal or analogous Freight.
FORGE
We, FRANCIS LAURENCE LANE, Engineer, and THE LEEDS
COMPANY, LIMITED Engineers and Ironmasters, both of The Leeds Forge,
Leeds, in the County of York, do hereby declare the nature of this invention to
be as follows:-
This invention relates to an improved construction of waggons whereby coal or
analogous freight may be transported by railway or tramway with less tare than
has heretofore been usual, and which construction is also designed to facilitate the
ready discharge of the freight and to enable truss rods to be dispensed with. In
this improved construction the sole bars are made with a central portion of
considerably greater depth than the end portions, to which the said deeper portion
is connected by parts of gradually diminishing depth. Each such sole bar may be
formed of a single plate pressed to shape with appropriate flanges, the lower of
which may support transverse members hereinafter mentioned, but other ways of
forming sole bars such as referred to might be adopted. The bottom of the
central portion of the waggon body is supported at about or a little above the
level of the lower edges of the sole bars. Between the sole bars there are
transverse members which are adapted to support the bottom of the hopper like
waggon body which is also supported by the sole bars. The said bottom is
composed of or provided with doors which meet along the longitudinal centre line,
or approximately so, of the waggon body and are provided with mechanical means
whereby two doors one arranged at each side of the said centre line and constituting
a pair may be simultaneously moved laterally either outward or inward for the
purpose of opening or of closing the same. There may be two or more pairs of
doors. A convenient arrangement for operating the doors comprises a screw with
right and left hand threads, but other mechanical devices might be employed. In
order that the doors may be readily opened notwithstanding the friction due to
the load upon them antifriction wheels or rollers and ways for the same are or may
be provided. Provision is made for sheltering and protecting the door operating
mechanism and the antifriction wheels or rollers and ways. From the waggon
bottom the sides and ends of the waggon body are inclined upward to suitable
points at an angle or angles such that the load will be readily discharged when the
bottom doors are opened.
The waggon body and frame or either can be constructed of steel or iron, or
wood may be employed in the construction of either, and they can be carried by a
couple of bogie trucks or by any convenient or suitable arrangement of axle
boxes axles and wheels with or without springs.
The accompanying illustrative drawings will serve to indicate the nature of
improvements forming the subject of the present invention and their embodiment
in a convenient construction of waggon whereof the body and framing are or may
be of steel,
Fig. 1 being a side elevation of rather more than half of the waggon and

A, A, are sole bars; B, B, sliding doors; D, D, transverse members;
E, E, inclined ends of the waggon body; F, F, inclined sides thereof; G, G, bogie
trucks; H, H, pressed steel stanchions of trough shape which are rivetted to the
sole bars and to which the sides of the waggon body are also rivetted. The nature
of other details will be understood from the drawings.
As will be evident the construction illustrated may be modified and in building
waggons according to this invention it may be found convenient to adopt some
only of the several improvements hereinabove indicated or embodied in the
improved waggou illustrated by way of example.

Improvements in Waggons suitable for the Conveyance by Railway
or Tramway of Coal or analogous Freight.
We, FRANCIS LAURENCE LANE, Engineer, and THE LEEDS FORGE
COMPANY, LIMITED, Engineers and Ironmasters, both of The Leeds Forge,
Leeds, in the County of York, 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 an improved construction of waggons whereby coal or
analogous freight may be transported by railway or tramway with less tare than
has heretofore been usual, and which construction is also designed to facilitate the
ready discharge of the freight and to enable truss rods to be dispensed with. In
this improved construction the sole bars are made with a central portion of
considerably greater depth than the end portions, thereby increasing the carrying
capacity or the waggon. The said deeper portion is connected to the said end
portions by parts of gradually diminishing depth. Each such sole har may be
formed of a single plate pressed to shape with appropriate flanges, the lower of
which may support transverse members hereinafter mentioned, but other ways of
forming sole bars such as referred to might be adopted. The bottom of the
central portion of the waggon body is supported at about or a little above the
level of the lower edges of the sole bars. Between the sole bars there are
transverse members which are adapted to support the bottom of the hopper like
waggon body which is also supported by the sole bars. The said bottom is
composed of or provided with doors which meet along the longitudinal centre
line, or approximately so, of the waggon body and are provided with mechanical
means whereby two doors, one arranged at each side of the said centre line and
constituting a pair, may be simultaneously moved laterally either outward or
inward from either side of the waggon for the purpose of opening or of closing
the same. There may be two or more pairs of doors. A convenient arrangement
for operating the doors comprises a screw with right and left hand threads, but
other mechanical devices might be employed. In order that the doors may be
readily opened notwithstanding the friction due to the load upon them, antifriction
wheels or rollers and ways for the same are or may be provided. Provision is

page_text: made for sheltering and protecting the door operating mechanism and the anti-
friction wheels or rollers and ways. From the waggon bottom the sides and
ends of the waggon body are inclined upward to suitable points at an angle
or angles such that the load will be readily discharged when the bottom doors
are opened.
The waggon body and frame, or either, can be constructed of steel or iron, or
wood may be employed in the construction of either, and they can be carried by a
couple of bogie trucks, or by any convenient or suitable arrangement of axle
boxes, axles and wheels, with or without springs.
The illustrative drawings filed with our Provisional Specification will serve to
indicate the nature of improvements forming the subject of the present invention.
and their embodiment in a convenient construction of waggon whereof the body
and framing are or may be of steel,

A, A, are sole bars; B, B, sliding doors; D, D, transverse members;
E, E, inclined ends of the waggon body; F, F, inclined sides thereof; G, G, bogie
trucks; H, H, pressed steel stanchions of trough shape which are rivetted to the
sole bars and to which the sides of the waggon body are also rivetted.
Each door B is provided with four antifriction wheels or rollers mounted to run
in the adjacent transverse channel shaped members D which are suitably arranged
for the purpose as shown in Fig. 5. The doors constituting each transverse pair
of doors are provided at or about the centre of their length with upward extensions
that are engaged with a transversely arranged screw and (Figs. 2 and 4) provided
with right and left handed threads and with a hand wheel at each end, the
arrangement being such that the doors constituting a pair can be simultaneously
opened or closed from either side of the waggon by suitably turning the screw.
The nature of other details will be understood from the drawings.
As will be evident the construction illustrated may be modified, and in building
waggons according to this invention it may be found convenient to adopt some
only of the several improvements hereinabove indicated or embodied in the
improved waggon illustrated by way of example.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A waggon suitable for the conveyance by railway or tramway of coal or
analogous freight, constructed with sole bars made with a central portion of greater
depth than the end portions, thereby increasing the carrying capacity of the
waggon, and connected to such end portions by parts of gradually diminishing depth
substantially as described.
2. A waggon constructed with sole bars as specified in the preceding claim and
with a hopper like body the bottom of which is supported at about or
a little
above the level of the lower edges of the sole bars, and the sides and ends of
which are inclined upward from the waggon bottom to suitable points at an angle
or angles such that the load carried can be readily discharged through a
suitable opening or openings in the bottom of the waggon, substantially as
described.
3. A waggon of the kind referred to in the preceding claims having its bottom
composed or provided with doors which meet along the longitudinal centre line, or
approximately so, of the body, and are provided with mechanical means whereby
two doors, one arranged on each side of the centre line and constituting a pair,
can be simultaneously moved laterally either outward or inward from either side

page_text: of the waggon for the purpose of opening or closing the same, substantially as
-described.
4. A waggon having a hopper like body and suitable for the conveyance by
railway or tramway of coal or analogous freight, constructed substantially as
described and shown.
