Draughtsman do hereby declare the nature of this invention to be as follows:-
This invention has for its object the prevention of accidents, and also the saving
of time when fastening, or unfastening the End Doors of Railway wagons or like
Vehicles; and is arranged that the door can be fastened, or unfastened, and locked,
or unlocked, from either side of the Vehicle, to which it may be attached, thus
obviating the necessity of the dangerous practice of rossing the Railway lines,
which is now often necessary with the fastenings at 1resent in use. The present
method of securing End Doors most largely adopted, is by means of an iron or steel
flat bar, called a fa-tening bar, which extends across the end door, and engages
with projections on 2 catches, one on each side of the vehicle, one being placed
above, and the other below the bar, which is fitted near the centre with a swivel
stud on which it works. It has also near each end a guide staple, which guides
the movement of the bar, which staples have sufficient space left respectively above
and below them, as to simultaneously allow it to rise and fall or disengage with
the catches, when unfastening the door. A falling pawi is used near one side of
the wagon above the bar, to prevent it from being forced from its position when
fastened (by accident or otherwise). This pawl is placed near one side of the
wagon only, and if the operator be on the opposite side, and wishes to open the
door, he has to cross over the railway line to release the said pawl, which is a
dangerous practice.
My invention consists of the introduction of a locking bar, which extends across
the end door from one guide staple to the other, and rests upon the top of the
fastening bar, both being held close together by means of a metal strap, or straps,
this locking bar is arranged to slide on the top of the fastening bar, and when
the door is fastened and the fastening bar engaged, this locking bar can be actuated
from either side of the wagon, and be forced into, and be made to fill up, the
space in the guido staple, and prevent the door from becoming unfastened, except
at the will of the operator. When using the locking har &c, the nawl which is
now in use near one side, can be dispensed with. I modify this improved locking
fastener to suit requirements, I may use a spring in place of the locking bar, or
by another modification use a link or links of metal placed vertically to secure
the fastening bar in the catches.

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
-
The object of this Invention is to prevent accidents and also to save time when
fastening or unfastening the end doors of Railway wagons and like vehicles and to
dispose of the dangerous practice of persons crossing the Railway lines, which is
often necessary when fastening or unfastening the end door fastenings now
generally in use.
For this purpose in an end Door fastening according to my invention, a locking
bar is placed across the end door held in position by means of metal straps and
accessible from either side of the vehicle to which it may be fitted, and in order
that my invention may be clearly understood I will proceed to describe the
same with the aid of the accompanying drawings in which
Fig. 1. is an end elevation of a Railway wagon showing my invention with the
end Door fastened, in this arrangement I show the end Door fastening now
generally used but modified and with my invention added, The fastening bar. 1
extends across the end door and engages with projections on the catches. 2. and. 3.
and is fitted near the centre with swivel stud. 4. on which it works. and is guided
by staples. 5. and. 6. which staples have sufficient space left above and below
respectively to, simultaneously allow the fastening bar. 1. to rise and fall and dis-
engage from the catches 2 and. 3. when unfastening the end Door
My invention consists of the introduction of Locking Bar. 7. which rests upon
and slides on the top of the fastening bar. 1. both being held together by means of
mtals 8 and 9, and when the den is fastened as shown the locking bar. 7.
Hiis up
the space. in the staple, and prevents the fusiening bar. 1 from remingg
unfastened, a roller 10 is placed in recesses 13 and. 14. formeal in the tastening bag 1.
and the locking bar. 7. respectively to prevent the locking bar. 7. from moving by
vibration, Projections. 11. and. 12. are formed or fixed on the locking bar. 7.
for use as handles in pushing and pulling the bar.
To unfasten the end door it is necessary to slide the locking bar. 7. untill it is
clear of the staple. 5., the fastening bar 1 can then be disengaged from the
catches 2 and 3, and the door opened.
Figs. 2 and. 3. show elevation and plan of the locking bar. 7. with projections
11. and. 12 and recess. 14.
Figs 4 and. 5. show elevation and plan of the fastening bar. 1. with recess. 13.
Figs. 6. and. 7. shows side and end elevation of Metal straps 8 and 9.
Fig 8 shows side elevation of Roller 10.
The fastening may be made in iron steel or other metal.
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
Fastenings for End Doors of Railway Wagons and like vehicles in which a
locking bar is used, and which can be fastened and unfastened from either side of
the vehicle without the necessity of crossing the Railway lines, and constructed
subsantially as hereinbefore described with reference respectively to, and shown
in l'ig: 1. 2. 3. 4. 5. 6. 7 and 8 of the accompanying drawings.
