Improvements in Draw-bar Plates for Railway Vehicles
I, JOHN ATKINS ADEY 818 Ashton Old Road, Openshaw, in the County of
Lancaster, Manager, do hereby declare the nature of this invention to be as
follows:-
!
!
This invention relates to an improvement in the construction of draw-bar plates
for railway vehicles, the object being to increase and, strengthen the wearing
surface of the lower part of the aperture through which the draw-bar works.
The draw-bar plate is a metal plate, say fifteen inches by eight inches, and three
“quarters of an inch thick, (but the size is immaterial) having bolt holes and a
central oblong rectangular hole or opening for the passage of the draw-bar, which
rests upon the bottom edge and moves backwards and forwards through the said
opening. The plate is fixed to the front of the wagon frame.
:
In carrying out the invention, instead of cutting out a rectangular piece, say for
example three inches deep, by two and a half inches wide from the plate, and thus
leaving the bottom edge of the opening the thickness of the plate only: I divide
or cut through the metal on the top and two vertical sides, and I bend back the
piece so released, until it is at a right angle, or horizontal, or thereabouts with the
back of the plate.
The piece so situated forms a bracket or support upon which the draw-bar rests
and by this additional support and wearing surface the life of the draw-bar is
greatly extended.

Improvements in Draw-bar Plates for Railway Vehicles.
1, JOHN ATKINS ADEY 818, Ashton Old Road, Openshaw, in the County of
Lancaster, Manager 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 :-
This invention relates to an improvement in the construction of draw-bar plates
for railway vehicles, the object being to increase and strengthen the wearing
surface of the lower part of the aperture through which the drawbar works, and
upon which it is supported.
The annexed sheet of drawings illustrates one of the plates made according to
my invention.

I will premise that a draw-bar plate is usually a metal plate of about fifteen
inches long by eight inches deep, and three quarters of an inch thick, but these
sizes may be varied as desired and are only given as an example.
It is provided with bolt holes by which it is secured to the wagon, and a central
oblong rectangular hole or opening for the passage of the draw-bar which rests
upon the bottom edge of the hole and is constantly moving in and out when the
train is in motion.
i
In carrying out my invention instead of cutting completely out a rectangular
piece to form the hole H, say for example three inches by two and a half inches
and thus leaving the bottom edge of the hole the thickness of the plate only, say
three quarters of an inch, I divide or cut through the metal of the plate upon the
top T, and two vertical sides S, and I bend back the piece R, so partially released,
until it is at a right angle or horizontal or thereabouts with the back of the
plate P.
The piece R, so cut and situated forms a supporting bracket upon which the
draw-bar rests and moves and by this additional wearing surface which cannot
move from its fixed position the life of the draw-bar and of the plate is greatly
extended, and the use of loose plates and other make shifts is avoided.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:..
1. The improved draw-bar plate as herein before described, and shown.
2. A draw-bar plate constructed with a supporting plate R, made from the
same continuous metal as the plate itself for the purpose specified substantially as
bereinbefore described.
