Complete Specification Accepted, 8th June, 1889
I, JOSEPH KAYE, of Bank House, Kirkstall, Leeds, in the County of York, Lock
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to lock at will Drawers, Doors, Desks, Lids, or the
like, without the trouble of using a Key, and to make the lock as secure as if locked
by its key.
I accomplish my object in the following manner.
The lock may be made in what is known as the Rim, Flush, or Mortice form.
The lock-bolt is held in by a catch, or its equivalent which resists the pressure
of a spring, set for the purpose of pushing out the lock-bolt when the said catch or its
equivalent is released, as in my patent No 17,021, December 10th 1887.
When it is desired to shoot out the lock-bolt to lock the drawer, door, desk, lid or
the like, the said catch or prop is released at pleasure, by pressing a piston in the
centre of the handle of the drawer, door, desk, lid or the like, or by releasing
the catch, or its equivalent, when the spring will force out the lock-bolt and secure
the fastening.
The lock-bolt may also be forced out by pressure upon the piston in the knob,
or by any other suitable means, and so lock the drawer, desk, door or the like,
without using the key of the lock.

Agent.

I, JOSEPH KAYE, of Bank House, Kirkstall, Leeds, in the County of York, Lock
Manufacturer, 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 this invention is to lock at will drawers, desks, lids, and the like,
without having the trouble of using a key for the purpose, and to make the lock as
secure as if locked by its key and consists in constructing the lock bolt so that
when withdrawn it may be held by a catch to resist the pressure of a spring set
for the purpose of pushing out the lock bolt on releasing the said catch by the
operation of a piston or bar or the lock bolt may be "shot" by arranging the piston
or bar connections to act direct on the lock bolt.
In the accompanying drawings,
C
Fig. 1. represents the interior of a lock made according to my invention in which
the lock bolt is held withdrawn by a catch.
Fig. 2. is a side view of the same.
Figs. 3. and 4. are similar views' with the lock bolt "shot" showing how it may be
operated without the aid of a spring.
Fig. 5. represents a view of a lock made according to my invention having levers
of another description the lock bolt being held by a catch.
Fig. 6. is a similar view with the lock bolt "shot" showing how it may be
operated without the aid of a spring, and,
Fig. 7. is a side view.
The lock plate is of the ordinary construction and indicated by the-letter A. and on
the pin B. are hinged a series of levers C. the upper portion of which are recessed
at D. and undercut on one side which when the lock bolt E. is withdrawn as
shown by Fig. 1. engages with the undercut or bevelled surface in the recess F.
of lock bolt.
On one side the lock bolt, is mounted a catch G. which engages with a projection
on the lock bolt when withdrawn. Mounted near one arm of catch G. is a small
bell crank lever H. fulcrumed on a pin, one arm or leg of the lever being in contact
with an arm of the said catch, and to the other arm or leg of the bell crank lever H.
is jointed a piston or bar J. that extends some distance beyond the face of the wood
work to which the lock may be attached, so that on pressing the piston or bar J.
towards the back of the lock plate, the bell crank lever is operated and the catch G.
moved on its fulcrum pin K. such a distance that, it releases its hold of the lock
bolt E. thereby liberating the same so that a spring S. acting on some part of the
lock bolt causes it to "shoot" and secure the drawer, or the like, the levers C.
moving into the position shown by Fig. 3. thereby preventing the lock bolt being
withdrawn except by the action of a key.

page_text: It will be easily understood by persons conversant with locks, that by placing the
bell crank lever in a position as shown by Figs. 3. and 4. to act direct on the lock
bolt E. it may be operated without a spring S. by pressing the piston or bar J.
towards the back of the lock plate as before described, one arm or leg of the bell
crank lever by being in contact with the lock bolt will push the same outwards and
thereby secure the drawer, door, or the like, the levers preventing the lock bolt E.
being withdrawn except by the action of a key and when the lock bolt is withdrawn
it is held in that position by the ends of the several levers C. engaging with the
undercut portion of the recess F. of the lock bolt.
My improved lock may be arranged with levers C. having wards in the centre,
in which case the catch G. may be mounted on the side for retaining the lock bolt E.
and liberated by a bell crank lever H. so that a spring S. will operate and shoot the
lock bolt E. in the manner as hereinbefore described, or the catch G. and spring S.
may be dispensed with and the bell crank lever placed so as to act direct on the
lock bolt and operate the same whenever the piston or bar J. is pressed towards
the back of the lock plate, the lock bolt when withdrawn being held in that position
by the levers C. pressing against the pin P. as in an ordinary lock.
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 combination of a bell crank lever with a lock bolt E. by which the same
is operated on pressing the piston or bar J. as and for the purpose hereinbefore
described.
2. The combination of a lock bolt E. with a lever or its equivalent by which the
lock bolt may be operated in an outward direction substantially in the manner and for
the purpose as hereinbefore described.
