Improvements in Bolts.
We CHARLES FOSTER KITE, and WILLIAM CHRISTOPHER BARNS; both of
Christopher Works, Chalton Street, London, Engineers, do hereby declare the
nature of this invention to be as follows:-
According to this invention the bolt and likewise the eye into which it takes are
tapered, while the bolt is provided with a talon into which a key or handle fits,
whereby the bolt is operated. Such key or handle may either be fastened in the
bolt or be made to take in and out. The bolt is mounted on a suitable base plate
and is kept in position by a cap which forms a socket wherein it works to and fro.

Improvements in Bolts.
We, CHARLES FOSTER KITE, and WILLIAM CHRISTOPHER BARNS, both of
Christopher Works, Chalton Street, London, Engineers, 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 ensure the head of the bolt readily taking into
the staple or eye when the woodwork is shrunk or warped, and also to enable the
bolt to be converted into a lock bolt when desired, thus affording increased security.
Also to obtain a more desirable method of moving the bolt than by the ordinary
parallel push or pull.
To effect this we make the bolt, and likewise the staple or eye into which it
takes, taper, while the bolt is provided with a talon, which has a V groove formed
therein, into which a key furnished with a handle, whereby the bolt is operated,
fits. Such key and handle may either be fastened in the bolt, or they may be
made to take in and out like the key of a lock, so that by removing the same the
bolt can at once be converted into a lock bolt. The bolt is mounted on a suitable
base plate, and is kept in position by a metal cap which forms a chamber wherein
the bolt works to and fro.
The bolt, and likewise the staple or eye, may be of any convenient form, such as
rectangular, circular, or otherwise.
The accompanying drawing shews a plan view of a bolt and staple or eye made
according to our invention-a, is the bolt-a², the tapered ends thereof-b, the
conical staple or eye-c the talon of the bolt with the V groove formed therein―
d, the key which takes into such groove-e, the handle which is formed on or
fastened to such key, so as to constitute one piece therewith, the base plate
whereon the bolt is mounted, and g the metal cap which holds the bolt in position,
and forms the chamber wherein it works to and fro.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
A bolt having its ends tapered, so as to fit into a conical staple or eye, and

page_text: provided with a talon having a V groove formed therein, wherein a key provided
with a suitable handle fits, which key and handle may be made removable or not
as preferred, all substantially as hereinbefore described and shewn.
