COMPLETE SPECIFICATION.
Improvements in Railway Wagons.
I, CHARLES HUNT, of Windsor Street Gas Works, Birmingham, in the County
of Warwick, Civil Engineer do hereby declare the nature of my said invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention has for its object improvements in railway wagons and has special
reference to the operation of the discharging doors in hopper wagons shown and
described in Specification No. 2674 A.D. 1894 whereby I obtain greater power
in the manipulation of such doors and at the same time render them more easy and
free in their action.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto three double-sized sheets of drawings upon
which I bave fully illustrated the nature of my said improvements and the mode of
arrving the same into effect.
Figure 1, is a general longitudinal sectional elevation through a hopper wagon.
Figure 2, is an enlarged longitudinal section through the door and supports.
Figure 3, is an inverted plan of Figure 2.
Figure 4, is a similar section to Figure 2 but showing a modification in the mode
of and means for operating the doors.
Figure 5, is an inverted plan of Figure 4.
Figure 6, is also a similar section to Figure 2 but showing a further modification.
Figure 7, is an inverted plan of Figure G.
Figure 8, is a part sertion showing the application of a worm wheel to the
operation of the doors.
Figure 9, is a plan of Figure 8.
Figure 10, is a cross section showing the mode of operating the doors by a worm
and wheel.
Figure 11, is an enlarged sectional elevation of the rollers upon which the doors
slide.
Figure 12, is an elevation of Figure 11.
In carrying my invention into effect my wagon A is provided with the inclined
ends which are placed at such an inclination as to deliver the whole of the
material contained in the wagon on to the doors B which are provided at the
bottom of the hopper and are mounted to slide backwards and forwards from or
under the two holes formed in the bottom of the wagon for the delivery of the
contents.
The operation of the doors is effected by means of the toothed wheels el upon
the shaft operating the rack C which is fixed upon the face of door B and for
the purpose of obtaining increased power in the operation of the doors the spur
wheel F is provided which is mounted to operate intermediately between the
wheel H on the handle shaft and the beforementioned tooth wheel and is
placed at each side of the wagon in the recess formed by the inclined sides of the
wagon. Handles or square heads J¹ to receive such handles are provided at
each side the wagon for the operation of the doors and the spindle or shaft E may
extend from one side of the wagon to the other in which case both doors would be
opened simultaneously or the shaft E may be in two parts in which case each door
would then be operated separately. It would generally only be necessary to keep a
handle at each destination of the wagon.

page_text: The wagons may be provided with the arrangement shown by Figures 4 and 5 for
opening and closing the doors in which case the mitre or equivalent bevil wheels,
are provided on the shafts E so as to engage with similar wheels ¹ upon the
longitudinal screw threaded shafts K the screw of which engages with the
internally tapped sockets 61 formed upon the doors B. In place of two screw
shafts K only one similar shaft L may be provided as shown by Figures 6 and 7
being in this case mounted centrally between the two doors and engaging with the
socket M of the crosshead M which is attached to each door at b
In both oi
these modifications the handles J may be attached direct to the shaft E at each
side. In place of operating the screw rods K or L through the mitre or bevil
wheels they may be operated through the wheels by the worm Figures 8, 9,
and 10.
•
To prevent any interference with the sliding of the doors by clogging with coal
dust I perforate the angle iron bearers P which assist to carry the rollers R at 1
and form the intermediate strengthening pieces 22 which are inclined upon their
top surface so as to direct the dust down from the runners or rollers which are
supported upon the pins and carry the angle iron sides of the door B. The
angle irons P are bolted to the frame S of the opening T and may be secured by
bolts passing through the strengthening pieces 22 which pieces are generally cast
in one piece with the support P but may in the case of wrought iron be attached
separately.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
t, .
1st. The improvements in railway hopper wagons substantially as and for the
purpose herein set forth and shown upon the accompanying drawings.
2nd. In railway hopper wagons the mode of and means for operating the
doors B substantially as and for the purpose herein set forth and shown upon the
accompanying drawings.
3rd. In railway hopper wagons the mode of mounting or supporting the doors
upon their runners and the construction of the runners substantially as and for the
purpose herein set forth and shown.
Dated this 29th day of November 1891.
