PROVISIONAL SPECIFICATION.
Improvements in the Method of Securing Coupling-chains in their
Position on the Draw-bar of Carriages or Wagons.
We, JAMES BLACKBURN of 30 East Parade, Colliery Engineer, and JOHN EDWARD
DAVENPORT of 36 Call Lane, Iron Merchant, both of Leeds in the County of York,
do hereby declare the nature of this invention, to be as follows:-
The object of our invention is to construct apparatus whereby the chains hanging
from the "draw-bar" can be loosely but securely held on such "draw-bar," at the
same time to provide an easy method of detaching the same when required for
repairs, renewals or other purposes, and without removing the "draw-bar."
For the above purpose we recess the top of the "draw-bar" sufficiently deep to
allow a link of the chain to be dropped into it, and so that a bevelled sliding piece or
slip can be fitted in the recess above the link; this being done, a pin is passed
through a projecting piece in the " draw-bar," through the bevelled piece or slip
and through another projecting piece on the "draw-bar," such pin being then rivetted
whereby the slip or loose piece is prevented from dropping out, consequently the
chain cannot get out of position, at the same time the pin can easily be removed and
the slip or bevelled piece withdrawn and the chains taken off for repairs, renewals or
other purposes.

COMPLETE SPECIFICATION.
Improvements in the Method of Securing Coupling-chains in their
Position on the Draw-bar of Carriages or Wagons.
We, JAMES BLACKBURN of 30 East Parade, Colliery Engineer, and JOHN EDWARD
DAVENPORT of 36 Call Lane, Iron Merchant, both of 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:-
The object of our invention is to construct apparatus whereby the chains hanging
from the draw-bar can be loosely but securely held on such draw-bar, at the same
time to provide an easy method of detaching the same when required for repairs,
renewals or other purposes, and without removing the draw-bar.
In the accompanying drawings Fig. 1 is a perspective view of draw-bar and hook.
Fig. 2 is an enlarged view of slip. Fig. 3 shows an enlarged view of portion of
draw-bar into which the slip is fitted.
A is the draw-bar, and B the hook at the end thereof.
For the above purpose we recess the top of the draw-bar A at C, sufficiently deep
to allow a link of the chain to be dropped into it as shewn in dotted lines, and so that
a bevelled sliding piece or slip D can be fitted in the recess above the link this being
done a pin E is passed through the projecting piece F in the slip D, through the
bevelled part G in the draw-bar, and through another projecting piece F¹ in the slip D,
such pin being then rivetted whereby the slip or loose piece B is prevented from
dropping out, consequently the chain cannot work out of position, at the same time
the pin E can easily be removed, the slip or bevelled piece D withdrawn, and the
chain removed for repairs, renewals or other purposes.

page_text: Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we
claim is :-
1. The arrangement and construction of loose piece or slip D with its pin E,
applied in recess of the draw-bar A, substantially as and for purposes herein set
forth.
2. The arrangement, construction and combination of hook B, draw-bar A, and
loose piece or slip D, substantially as herein set forth.
Dated this 20th day of September 1890.
