We, ARTHUR AUSTIN, of 38, Wellington Street, Carpenter and Joiner, and EDWARD
PEARS CAPORN, of 48, Prebend Street, Cycle Manufacturer, both in Bedford,
in the County of Bedford, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved fastening for doors and the like designed to
serve in lieu of a bolt.
Our improved fastening comprises two plates hinged together one of which herein-
after termed the base plate is adapted to be fixed in the rebate of the door frame so
that it is parallel with the edge of the door when the latter is closed, whilst the other
hereinafter termed the lock plate is designed to be turned against the face of the
door when closed and form an abutinent to prevent the opening of the same.
To prevent the movement of the lock plate relatively with the base plate when
the said lock plate is turned to secure the door, the said lock plate has the hole
through which the hinge pin passes elongated so that when at right angles to the
base plate it can slide in a longitudinal direction. The projecting part of the lock
plate then forms an abutment which co-operates with an abutment on the base plate
to prevent, the movement of the lock plate upon the hinge pin until the said lock
plate is again moved forwards.

An Improved Fastener for Doors and the like.
We, ARTHUR AUSTIN, of 38, Wellington Street, Carpenter and Joiner, and
EDWARD PEARS CAPORN, of 48, Prebend Street, Cycle Manufacturer, both in
Bedford, in the County of Bedford, 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:-
This invention relates to an improved fastening for doors and the like designed
to serve in lieu of a bolt.
Our improved fastening comprises two plates hinged together, one of which,
hereinafter termed the base plate, is adapted to be fixed in the rebate of the door
frame so that it is parallel with the edge of the door when the latter is closed, whilst
the other, hereinafter termed the lock plate, is designed to be turned against the

page_text: face of the door when closed and form an abutment to prevent the opening of the
same.
To prevent the movement of the lock plate relatively with the base plate when
the said lock plate is turned to secure the door, the said lock plate has the hole
through which the hinge pin passes elongated so that when at right angles to the
base plate it can slide in a longitudinal direction. The projecting part of the lock
plate then forms an abutment which co-operates with an abutment on the base plate
to prevent the movement of the said lock plate upon the hinge pin until the said
lock plate is again moved forwards.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is an elevation shewing the application of our improved fastener to a
door; and
Figure 2 is a section on the line 2-2 of Figure 1:
Figure 3 is a view similar to Figure 2 shewing the lock plate in its unlocked
position:
Figure 4 is an end view of the fastener.
a is the base plate which is adapted to be fixed to the frame of a door, for instance
by means of a screw bas; shewn, and c is the lock plate which is hinged or pivoted
to the base plate a by the pin d. e is the elongated hole or slot in the lock plate c
through which the pin & passes.
It will be understood that when the lock plate is in the position shewn in Figure 3
it can be turned upon the pin d, for instance to the position indicated by the dotted
lines in the said figure; if, however, when the lock plate is lying against the face
of the door, as shewn in Figure 3, it is pushed from this position to that shewn in
Figure 2, it will be obvious that the end of the lock plate adjacent to the pivot will
be in such relation to the base plate that it cannot be turned, that is to say, the
part of the base plate will form an abutment against which the hinged end of the
lock plate will lie.
It is to be understood that both the base plate and the lock plate may be of any
desirable shape or ornamentation and that our improved fastener may be applied
not only for fastening doors but also for fastening windows, box lids and the like.
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. A fastener having two plates hinged together one of which is designed to be
fixed whilst the other is movable upon a hinge pin the said movable part being
provided with an elongated hole or slot which permits of moving the said hinged
portion relatively with the hinge pin in a longitudinal direction, substantially as, and
for the purpose, described.
2. The manufacture and use of the improved fastener hereinbefore described and
illustrated in the accompanying drawing.
