Chains or Links.
I, JOHN JAMES JONES, Deputy Locomotive Superintendent, Rajputana Malwa
Railway, Public Works Department, Government of India, residing at Ajmere in
the province of Rajputana, in the East Indies, do hereby declare the nature of my
invention for IMPROVEMENTS IN APPLIANCES FOR LOCKING OR SECURING DOORS,
COVERS, CASES, GATES &c., as above described, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement
For the better performing and convenience of this purpose a drawing is attached
and figured and lettered, representing generally six only of the various forms which
the general arrangement of the parts hereafter described would assume when
combined and placed together. The same letters apply to the same parts or arrange-
ments in the several figures and represent the parts hereinafter particularly described
and ascertained, viz :-
(a) The hook, claw, link or bar.
(4) The locking device.
(c) The locking bolt, claw or jaw.
(d) The staple, catch, link or eye-bolt.
(a). The hook, claw, link or bar.
(b). The locking device.
(c). The locking bolt, claw or jaw.
(d). The staple, catch, link or eye-bolt.
The hook, claw, link or bar (a) is of a suitable form to be fixed or attached at one
part to one or the other closing, meeting, or abutting, parts of an opening, cover,
case, gate, chain, or adjoining part; and at another part to engage with the staple,
catch, link or eye-bolt (d); and to form part of, or carry or hold the locking
device (b).
The locking device (b) is fixed in a suitable position to the above-described hook,
claw, link or bar, or may form part thereof and may be controlled by a key. The
locking bolt, claw or jaw (c) is of suitable form to engage with the locking device or

page_text: some portion thereof, or may be a part thereof, and be held and secured or released
thereby or permitted to move within suitable limits thereby; and to engage with the
staple, catch, link or eye-bolt (d) or to abut against, meet or approach a suitable part
of the above described hook, claw, link or bar, or a suitable part of the above described
locking device. At one part the said locking bolt, claw or jaw may be attached and
secured to the above described hook, claw, link or bar or to the above described
locking device, or to other suitable parts.
The staple, catch, link or eye-bolt (d) is of suitable form to engage with the before
described hook, claw, link or bar and with, or with the above described locking bolt,
claw or jaw and is fixed or attached to one or the other parts of the before mentioned
closing, meeting or abutting parts of an opening, cover, case, gate, chain or adjoining
part.
The general combination of the parts above described, or such thereof as may be
suitable, forms a locking appliance in which, the locking device, controlled by the
before mentioned key locks or holds the locking bolt, claw or jaw in a suitable or
locked position; or in a suitable or open position; or disengages from the locking
bolt, claw or jaw, and permits the said locking bolt, claw or jaw to move within
suitable limits. (The locking appliance may be termed a combined book-lock, claw-
lock, link-lock or bar-lock).
The general arrangement of the parts before described or such of them as may be
suitable forms an improved appliance for locking or securing doors, covers, cases,
gates or other means for closing openings, or chains or links, which may be controlled
by the before mentioned key.
The before described hook, claw, link or bar engages with the before described
staple, catch, link or eye-bolt. The before described locking bolt claw or jaw engages
with the said staple, catch, link or eye-bolt or abuts against or meets or approaches a
suitable part of the before mentioned hook, claw, link or bar or a suitable part of the
before mentioned locking device the said locking device, controlled by the before
mentioned key, engages with the said locking bolt, claw or jaw and holds or secures
the said locking bolt, claw, or jaw, or disengages or releases the same and permits of
the same being moved.
The door, cover, case, gate or other means for closing openings, or chain or link
is held or secured; or released, or freed by the general arrangement, as before
described; and the said general arrangement is controlled by a key as before
mentioned.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
I. The fixing of the herein described locking device to the herein described hook,
claw, link or bar in the manner herein described.
II. The general combination of the parts herein described, or such of them as
may be suitable, so as to form an appliance in which the herein included and already
described locking bolt, claw or jaw may be secured or held or released by the before
mentioned controlling key or may be released by the before mentioned controlling
key, so that it may be moved within suitable limits
III. The general arrangement of the parts, herein described or such of them as
may be suitable, for forming an appliance for locking or securing doors, covers, cases,
gates or other means for closing openings, or chains or links controlled by the before
mentioned key.
