An Improved Catch or Fastening for Doors, Flaps, Shutters and
the like:
I, PERCY HULBURD, of the Hulburd Engineering Company, of 150, Leadenhall
Street, in the City of London, Contractors, do hereby declare the nature of this
invention to be as follows:
My invention relates to an improved catch or fastening for doors, flaps, shutters
and the like the said catch or fastening being very advantageously used in con-
nection with the doors or flaps of railway waggons.
The object of my invention is to provide a flap which is of simple construction
and which can be quickly operated to fasten or unfasten a door whilst at the same
time affording great security.
My improved catch or fastening is in the form of a pendulous arm which is
pivotally mounted upon the framing of the door, flap or shutter, the said door,
flap or shutter being provided with a plate having a horizontal slot and hole to
pass over the catch. In order to open or close the door or the like it is necessary to
move the pendulous arm to a horizontal position to correspond with the position
of the slot so that the latter will pass the catch.
It will be obvious that when the door or the like is closed and the catch hangs
vertically there will be no possibility of opening the said door.

An Improved Catch or Fastening for Doors, Flaps, Shutters and
the like.
I, PERCY HULBURD, of the Hulburd Engineering Company, of 150, Leadenhall
Street, in the City of London, Contractors, 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:-
My invention relates to an improved catch or fastening for doors, flaps, shutters
and the like the said catch or fastening being very advantageously used in con-
nection with the doors or flaps of railway waggons.
The object of my invention is to provide a catch or fastening which is of simple
construction and which can be quickly operated to fasten or unfasten a door
whilst at the same time affording great security.
My improved catch or fastening is in the form of a pendulous arm which is
pivotally mounted upon the framing of the door, flap or shutter, the said door,

page_text: flap or shutter being provided with a plate, hereinafter referred to as the lock-
plate, having a horizontal slot and hole to pass over the catch.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which:-
Figure 1 is an elevation illustrating the application of my improved catch or
fastening to a drop down door or flap such as is used upon railway coal-waggons;
and,
Figure 2 is a section on the line 2-2 Figure 1.
a is the door or flap to be secured and b is the framing around the same.
c is the pendulous arm pivotally mounted upon a pin d secured to a plate c
which as shewn in the drawing is fitted into and fixed in a recess formed in the
frame b; f, f being the fixing screws.
9 is the lock-plate which is fixed to the door a and provided with a tongue h
designed to lie upon or against the face of the plate e the said tongue having in
it the hole and the slot which permit, when the pendulous catch is moved to
the position indicated by the dotted lines in Figure 1, of the plate or tongue h
passing the pendulous catch and coming into contact with the plate c.
It will be obvious that in order to open or close the flap it is necessary to move
the pendulous arm to the horizontal position indicated and that when the door or
the like is closed the pendulous arm hangs vertically, as shewn in full lines in
Figure 1, so that there is no possibility of the said door opening.
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. In a catch or fastening for doors, flaps, shutters or the like, the combination
of a pendulous arm and a locking plate adapted to pass over the said pendulous
arm, a lot which permits of the locking plate thus passing being formed in a
horizontal or substantially horizontal position so as to render it necessary that the
pendulous arm should be moved into a substantially horizontal position for the
purpose of releasing or locking the door, substantially as described.
2. The manufacture and use of the improved catch or fastening for doors, flaps,
shutters, or the like, substantially as herein before described and illustrated in
the accompanying drawing.
