PROVISIONAL SPECIFICATION.
Improved Frame Plates for Pit Corves, Railway Wagons, and similar
Vehicles.
We THOMAS WHITE, of Thorpe Hesley in the Parish of Rotherham, in the
County of York, Engineer, and ERNEST THOMSON CORBITT of 20 Moorgate
Street Rotherham aforesaid, Solicitor, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in frame plates used in the construction
of pit corves, railway wagons and similar vehicles.
They are so constructed that the building of the corves or wagons is much
simplified and greater strength is obtained without adding to the weight of the
vehicle.
To attain these objects we propose to fix at each corner of the vehicle a double
grooved frame plate as shown in Fig. 1 of the annexed drawinge, or in some cases
a single groove frame plate as Fig. 2 may be used.
They are of angular configuration and the grooves A, are to receive the boards
which are slid down from the top and are secured by bolts passed through the
holes B, and the top boards.
In the frame plate Fig. 2, one set of boards will be inserted in the groove A, and
the other will be bolted in position, the bolts passing through the holes B.
This method of construction permits the rapid replacement of broken boards from
the rough usage these vehicles are subject to.
The frame plates extend from the top of the upper board to the "sole" or frame
of the vehicle to which they are attached by means of a depending flange C, and a
horizontal one D, and bolts or the like.
Upon each side of the vehicle we propose to fix one or more side plates shown
in Figs. 3. 4. 5. the outer side which is strengthened by ribs E, is shown in Fig. 3,
the edge view in Fig. 4, and the plan in Fig. 5. They are secured to the sides and
frame by bolts passing through the holes F, in the uprights, and through the
holes G, in the flange H.

Improved Frame Plates for Pit Corves, Railway Wagons, and similar
Vehicles.
We THOMAS WHITE, of Thorpe Hesley, in the Parish of Rotherham in the
County of York, Engineer, and ERNEST THOMSON CORBITT, of 20 Moorgate
Street Rotherham aforesaid, Solicitor, do hereby declare the nature of this
invention and in what manner the same has to be performed, to be particularly
described and ascertained in and by the following statement :-
Our invention relates to improvements in frame-plates used in the construction of
pit corves, railway wagons and similar vehicles.

With the use of these frame-plates the building of corves or wagons is much
simplified and greater strength and durability is obtained without adding to the
weight of the vehicle.
The annexed drawings illustrate fully our invention, and similar letters of
reference indicate similar parts in all the figures.
Fig. 1, is a perspective view of a corner plate with double groove.
Fig. 2, perspective view of corner plate with oue groove.
Figs. 3 & 4, two views of side plate.
Fig. 5, perspective view of modified corner plate.
Fig. 6, back of same with boards in position.
We construct our improved frame-plates shown in Figs. 1 and 2, as follows; the
upright portion U, is of angular configuration, the sides being made double so as
to form grooves A, to receive the ends of the boards I, shown in Fig. 6, which
are slid down one after another from the top and secured in position by bolts
passed through the holes B, and the top boards.
The corner plates are provided with horizontal base plates D, and when desired,
with a depending flange C, by which they are secured to the sole or frame of the
vehicle.
The corner-plate shown in Fig. 2, is constructed with one groove A, and one
plain side, to which the end boards are bolted through the holes B'.
In some cases we use side plates as well as the corner plates, these are shown
in Figs. 3 & 4, the outside is strengthened by ribs E, and they have a horizontal
baseplate H, and a depending flango F, but this may be cut off at G, if preferred.
In Figs. 5 and 6, we represent a modification of our invention in the construc-
tion of the corner-plates, the upright U, may have one or two grooves for the
ends of the boards I, as desired, but we cut away, or stop off a portion of the
upper part of the outer member of the upright as shown in Fig. 6, which leaves
the upper part of the boards I, exposed.
This part is covered by a strap of iron which is preferably carried completely
round the wagon, being bolted to the corner plate through the holes B, and finishing
flush with the surface of U.
The baseplate D, is of a simple rectangular form with two boltholes through
which bolts or screws are passed into the sole or frame.
The use of these frame plates in the construction of corves and like wagons permits
..of the rapid replacement of broken or worn out boards, these vehicles being subject
to much rough usage.
Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is to be performed, we declare that what we'
claim is :
1. The improved construction of frame plates for pit corves, railway wagons and
similar vehicles, as herein before described and substantially as illustrated in
Figs. 1, 2, 3 & 4, of the annexed drawings.
2. An improved corner plate for pit corves, railway wagons and similar vehicles,
as hereinbefore described and with reference to Figs. 5 and 6, of the annexed
drawings.
