1 NATHAN GOLD KIMBERLEY of New Southgate in the County of Middlesex
Engineer do hereby declare the nature of my said invention to be as follows:-
My invention has reference to that class of Bolts, Latches and Locks commonly
known as Mortise bolts, latches and locks.
.
The object of my invention is to facilitate the means of fixing the Bolt, Latch or
Lock (hereinafter termed Bolt) to the door or other article that requires to be bolted
latched or locked.
To effect this object I make the body or casing of the bolt of a convenient shape
(preferably round) to enable it to be inserted in a round hole bored into or through
the body of the door or other article with a flange for fixing to the face of the door
or other article. In some cases to give greater security or to improve appearances
a second flange may be fixed to the other side of the casing or to the door or other
article.
A second hole is bored from the edge of the door or other article for the bolt itself
to pass through.
The bolt can be operated by the usual lock spindle with suitable handles acting on
a lever passing through or in contact with the bolt or with a pin connected to the bolt
or by other suitable means.
A spring may be used to control the bolt in one of its positions.
The bolt may be fixed or locked in the position required either by a wedge or catch
acting direct on the bolt or on the lever or other portion of the mechanism acting on the
bolt or by other suitable means. Or the mechanism may be constructed to enable
one handle or its equivalent to be placed out of control over the bolt when required.

Engineer 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 that class of bolts latches and locks commonly known as
Mortice locks and has for its object to facilitate the means of fixing the fastening or
lock to the door or other article requiring to be fastened.
The construction of this Invention is as follows. The body or casing of the bolt
or lock or fastening is in preference constructed round but any desired shape may.
be employed-In order to secure the lock or fastening to the door a hole of the
required size, is bored in the face of the door with a centre bit or other tool and a
smaller hole is then bored in the edge of the door corresponding to the size of the
bolt. The body or casing of the fastening is then inserted in the face of the door.
A flange being formed on the face of the Lock casing to prevent it passing too far
through the door and another flange detached may be employed for better securing
the lock on the other side of the door and for ornamental purposes and the bolt of
the lock being partly or wholly detached is passed through the hole in the edge of the
door and a screw or pin is passed through the face of the Lock and through the bolt
to secure it in position in the casing the end of the bolt is made smaller or a shoulder
is formed thereon against which a spiral or other shaped spring abuts and controls
the action of the bolt. The bolt is actuated by handles of ordinary construction but
in simple latches or fastenings I prefer a lever shaped handle pivotted at one end and
having a slot formed at or near its centre through which a pin is passed connecting
it to the bolt so that on turning the handle the pin works against the sides of the slot
thus forcing the bolt back.
The bolt may be locked or fixed by means of a key, either by a catch or wedge
acting direct on the bolt or on a lever or levers or any part of the mechanism acting
on the bolt.
In order that my invention may be properly understood and easily carried into
effect I will now describe the drawings hereto annexed in which
to
Fig. 1 is a front elevation of a door or other fastener or catch constructed according
my invention.
Fig. 2 is a section of the same.
Fig. 3 is a front. elevation of a door or other fastener with locking mechanism
applied.
Fig. 4 is a section of the same shewing the catch connected by the spindle to the
handle for actuating the bolt.
Fig. 5 is a section showing the locking mechanism.
Referring now to Fig. 1 and 2 of the accompanying Drawings a is the body or
casing having the flange b which may be either in one with the casing a or separate
therefrom provided with screw holes 6₁ for securing the lock or fastener to the door,
c is the lever handle pivotted at d having a slot e in which works and connects the
bolt fa screw ping said pin works in the slot e and regulates the travel of the bolt.
The bolt being actuated by a spiral spring i fitting against a shoulder formed on the

page_text: end f¹ of the bolt f which end f¹ works in a hole j formed in one end of the casing a
thus keeping the spring in position and at the same time keeping the bolt in its
normal or locking position. On turning the handle in the direction of the arrow the
pin is acted on by the sides of the slot and being connected to the bolt forces it back
and compresses the spring. On releasing the handle the spring forces the bolt out
again to its, normal or locking position.
Referring now to Figs. 3. 4 and 5. of the accompanying drawings wherein like
letters of reference refer to similar parts In place of the lever hande c hereinbefore
described the ordinary handle and spindle are employed in which case the spindle
of the handle is passed through the casing a of the lock to one side and secured
thereto is a wedge or catch n¹ which works in a slot a¹ formed in the bolt f Fig. 4
said bolt f being actuated and kept in position by means of a spring as hereinbefore
described in reference to Figs. 1 and 2. When it is desired to lock the bolt in a
certain position a key of suitable shape is passed through a hole q in the face of the
lock and actuates a catch lever g¹ pivotted at h¹ and having a forked end j' into
which the blade of the key on being turned works-Formed in the bolt f is a wedge
shaped groove k¹ into which the other end of the lever g¹ fits, said lever is kept in
position in preference by means of a supplementary lever m¹ actuated by means of a
suitable flat or other shaped spring p.
Fig. 6 is an internal elevation and Figs. 7 and 8 are sections of an alternate method
of constructing fastenings or locks according to my Invention.
a represents the body or casing with flanges having screw holes b'. The bolt f
supported in the position shewn by the action of the spring i is free to be drawn in
hy the catch piece N' when moved by the ordinary spindle (shewn in Fig. 9)-For
convenience of construction and fitting the bolt f as represented is made up of
two parts.
With the aid of a suitable key entering the lock at key hole q the lever o centred
on pin p is raised the bolt f will then be thrown further out and become locked in
position by the lever o under the action of the spring r.
The fastening or lock represented by Figs. 9 and 10 differs only from that herein-
before described and represented at Figs. 3, 4 and 5 in the relative position and mode
of construction of its various parts.
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. The construction of fasteners or locks for doors and other purposes having a
detachable bolt constructed in one or more pieces actuated by means of a spring or
springs or its or their equivalent substantially as herein described and for the
purposes set forth.
2. The construction of locks or fastenings for doors of suitable shape having a
detachable bolt either in one or more parts for facilitating the fixing of same and
actuating substantially as herein described and shewn on the drawings hereto
annexed.
3. The construction of locks for doors and other purposes having a detachable bolt
actuated and locked as herein described by means of a lever or levers and spring
or springs or their or one or any of their equivalents substantially, as herein
described.
