I CHRISTOPHER LONGBOTTOM of No 27 Kirkgate Bradford in the County of
York Estate Agent and Auctioneer do hereby declare the nature of my invention
for FASTENING WINDOW-SASHES, DOORS, OR HAND BAGS, to be as follows:-
I use brass metal or other suitable material for making this fastener, and form
it by making an oblique hinge in a proper position, and at a suitable angle for the
purpose required, which hinge when open has no effect, but when closed, one arm
being fixed as a standard, the other arm projects at an angle forming a secure,
simple and inexpensive fastening which may be supplemented by a hook, padlock
or other appliance.
To carry out my invention I employ a standard made of brass or other suitable
material, which standard (when the fastener is employed for a window) is fixed to
the upper sash, and a loose arm is hinged obliquely to it, at such an angle that when
the hinge is closed the loose arm projects against the top of the lower sash, thereby
keeping the window closed, but by raising the loose arm the obliquity of the hinge
attaching it to the standard causes such loose arm to move into a perpendicular
position over the standard thereby removing it away from the lower sash and
unloosing the window.
It is obvious that the above fastener with slight modifications may be employed
for fastening doors, handbags stair rods and other purposes.

CHRISTOPHER LONGBOTTOM of No 27 Kirkgate Bradford in the County of
York, Estate Agent and Auctioneer do hereby declare the nature of my invention
for A NEW WINDOW SASH, DOOR AND HAND BAG FASTENER SUITABLE ALSO FOR
OTHER PURPOSES AS A FASTENER 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 a new fastener for windows and doors it is also
applicable to hand bags stair rods and other purposes as a fastener.
To carry out my invention I employ a plate, or arin attached by an oblique
hinge to the window sash, door or other object, in such a manner that when lifted
up it offers no impediment to the free opening of such window sash door or other
object, but when closed down the arm lies at an angle to its former position and
projects as a stop or shoulder thereby forming a simple, effective and secure
fastener.
In order that my invention may be fully understood I will describe the same
with reference to the accompanying Sheet of Drawings wherein similar letters of
reference refer to similar parts.
Figure 1 represents a side elevation of my invention applied to a window sash,
Figure 2 is a front elevation, and Figure 3 is a plan of the same.
A is a standard fixed to the top window sash B and a plate or arm C is secured
to the standard A by the oblique hinge D which hinge allows the arm C to be
turned up, as indicated by the dotted lines in Figure 1 thereby unfastening the
window sashes, A plate F is fixed to the lower sash G and formed with a curved
projection H which engages with a slot in the arm C and serves to draw the sashes
together when closing the fastener. A stop or pawl J is attached to the plate F
on the lower sash G and may be placed against the arm C when the fastener is
closed thereby preventing it being opened from the outside. The stop or pawl
may be made to close automatically.
Figure 4 is a front elevation of my invention applied as a door fastener. K is
the door cheek shewn broken off at each end, to which is fixed the standard A
carrying the arm C which arm when closed presses against a plate F fixed
on the door L and rests upon the projecting hook E used for pulling the door
open.
Figure 5 is a front elevation and Figure 6 a side elevation of my invention
applied as a fastener for stair rods.
The arm C is attached by the oblique hinge D to the standard A and hangs down
in front of the stair rod M retaining it in position. The action of the fastener is
similar to those hereinbefore described and the rod M may be removed on lifting
the arm C

page_text: 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
The application of an oblique hinge as a fastener for window sashes, doors, stair
rods and other analogous uses.
