Improvements in Locks for Doors and the like.
I, ARTHUR CRIPPS 66 Haberdasher Street, Hoxton London Caretaker, do hereby
declare the nature of this invention to be as follows :-
This invention relates to improvements in locks for doors and the like the object
being to provide a lock which may be employed as an ordinary latch lock when
required and by operating the lock by means of a key suitable bolts are operated
which secure the door or the like and at the same time lock the latch bolt.
In carrying out my invention I employ a sliding bar or bolt which is controlled
by a spring or the like mechanism. This bolt is locked in position by the wards,
and a projection upon this bolt engages in a slot or recess in the latch aforesaid and
so locks same. The sliding bolt aforesaid is connected by means of suitable levers or
rods to locking bolts which secure the door. The locking bolts when desired may be
controlled by springs, and the ends of same may engage in suitable sockets or the
like. One or more of the wards is provided with a projection upon which the key
acts and which gives the ward or wards a motion in two directions. The sliding
bolt may be lock by a suitable catch or clip. A pivoted lever is connected with said
bolt and which operates same through the medium of the key.

I, ARTHUR CRIPPS 66 Haberdasher Street, Hoxton London Caretaker, 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 improvements in locks for doo:s and the like, the object
being to provide a lock which may he employed as in ordinary latch lock when
required and by operating a lock by means of a key suitable bolts are operated which
secure the door and the like and at the same time lock the latch bolt.
In carrying out my invention 1 employ a sliding bar or bolt which is controlled
by a spring or the like mechanism. This bolt is locked in position by the wards and
the projection upon this bolt engages in a slot or recess in the latch aforesaid and so
locks same. The sliding bolt aforesaid is connected by means of suitable levers or
rods to locking bolts which secure the door. The locking bolts when desired may be
controlled by springs, and the ends of same may engage in suitable sockets or the
like. One or more of the wards is provided with a projection upon which the key
acts and which gives the ward or wards a motion in two directions owing to the

page_text: circular motion of the key which thus first raises a ward or wards & then lowers
the ward or wards. The sliding bolt may be locked by a suitable catch or clip.
A pivoted lever is connected with said bolt and which operates same through the
medium of the key.
In order that my invention may be fully understood I will now refer to the
annexed drawings in which :-
Fig. 1. is a side elevation of my invention in position upon a door.
Fig. 2. view of lock to enlarged scale.
Fig. 3. view of modified form of lever for operating the sliding bolt.
Referring to Fig. 1, the ends of. the bolt or sliding bar a are connected as shewn
to the bars by means of the connecting rods or the like c. These bars 6 are pivoted
at d to the door e and engage in the sockets fas shewn. The bolts g are operated hy
the bent or curved levers pivoted at i. By this arrangement it will be seen that
the movement of the sliding bar a will operate the bolts g and bars b so as to place
them in their locking or released position.
Referring to Fig. 2, a is the sliding bolt which is operated by a key, a' being the
key pin or aperture through the medium of the pivoted lever j, having a slot k which
engages on a pin upon the sliding bar or holt a; m is the latch controlled by the
spring n. This latch has a slot or recess o in which a pin or projection p carried by
the sliding bolt a engages so as to lock the latch m when the bolt a is in its locked
position. The ward q has the curved projection or piece r on same so that the key
which operates the wards will cause the ward q to move in two directions that is an
up and down-motion caused by the action of the key which has a circular motion,
this ward being controlled by any convenient form of spring when required such as
at t. If desired the sliding bolt a may be provided with a pin or projection which
engages on a projection or surface upon the latch so as to lock same when the sliding
bolt is in its locked position. It will be readily seen that the latch can be used in the
usual manner unless locked by the movement of the sliding bolt. The notches o¹ & o
are for securing the bolt a in its two positions by means of the sliding button or
catch o³.
Referring to Fig. 3 in this case the lever jis pivoted at n as before and has the
semicircular rack which engages in the rack or teeth w upon the sliding bolt a
and thus operates said sliding bolt a through the medium of a key as before.
Referring to Fig. 1, the opening to the socket piece is shaped as shewn so
that when operating the key and wards unless the key is turned so as to bring the
locking bolts opposite the apertures or openings f in the sockets the door cannot
be opened.
The bent or curved levers h are so bent or curved as shewn that when the bolts or
bars g are in their,locked position, pressure upon same will tend to lock the bent or
curved levers' in the locking position, and the same must be moved or operated by
the connecting reds c or levers before the bolts g can be withdrawn.
Although I have shewn one means of operating the locking bolts, it will be seen
that any convenient and similar arrangement may be employed to carry out this
object.
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 :-
1. The combined construction and arrangement of the various parts:substantially
as described.and illustrated herein.
2. In locks of the class herein described; a sliding bolt operating locking or
bolting bars through the medium of suitable levers or rods, said sliding bolt being
operated by a key which operates upon wards one or more of said wards having a
curved projection or surface upon same so that the movement of the key will give
said ward or wards a movement in first one and then another direction, said sliding
bolt locking or securing a latch when in its locked position substantially, as described
and illustrated herein.

page_text: 3. In locks of the class herein described socket pieces having openings or slots so
arranged that the bolt or bar can only leave the socket piece when in a certain position
that is opposite the opening or slots in the socket piece.
