PROVISIONAL SPECIFICATION.
Improvements in Locks.
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:-
This invention relates to certain improvements in the construction of padlocks,
windowlocks, and others, whereby greater security and strength is given to the lock,
and at the same time, simplicity of construction and greater facility in locking and
unlocking is afforded.
In the case of the padlock the construction is such as to prevent water, or dirt
entering the lock.
I accomplish the above objects by forming the lock in the first instance, in the
ordinary manner, so far as centreing the hook or bolt upon a pivot on one side of the
top of the casing-the other end of the hook or bolt varies in its formation from those
in use hitherto, but is passed within the lock case in the ordinary manner in order to
lock the same.
Within the lock case I mount levers on a centre or fulcrum, in such a manner that
when the bolt is pressed into the lock case, one end of each lever is pressed into a
notch in the bolt by its respective spring, and so locks the bolt fast; the levers are
formed and placed in such a manner, that by inserting at the bottom of the lock a
flat or other convenient form of key with notches at its end suitable for actuating the
levers the proper distance, when this key is placed in the opening at the bottom and
pushed up the guide or passage, which is of the form of the key, and pressed against
the levers the bolt is released by means of a spiral or other spring pressing the bolt
out of the lock, or clear of the levers.
Locks for windows, I make on the same principle, the bolt being moved by hand
when released by the key.

COMPLETE SPECIFICATION.
Improvements in Locks.
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 :-
This invention relates to certain improvements in the construction of padlocks,
window locks and the like in such a manner, that greater security and strength is
given to the lock, combined with simplicity of construction and greater facility in
locking and unlocking afforded.
In explaining my invention in detail, reference is made to the accompanying
drawings, in which Fig. 1. represents a view of a padlock made according to my
invention, the cover plates in this and the other side views of the locks are removed
to more clearly show the interior.
Fig. 2. is a section through line a. b.
Fig. 3. a view of a similar padlock having a different internal arrangement.
Th
s the same look showing the book in the position whan

page_text: In all the figures similar letters indicate similar parts where they appear.
To the padlock case A. is centred or hinged in the ordinary manner the hook B;
the opposite end of the same at B¹ is curved and different to those in use and as
hitherto constructed, but is passed within the lock case A in the ordinary manner,
when it is desired to secure the lock bolt.
Within the lock case A. I mount a series of levers D on a centre or fulcrum pin E
in such a manner that, when the end B₁ of hook B is pressed into the lock case, one
end of each lever D at D' is by its respective spring S. pressed into a notch F cut
or formed near the end of the hook, thereby automatically securing the same without
the use of a key.
The levers D. are formed and placed in such a manner that, by inserting in the
bottom of the lock through the slot hole G. a flat or other convenient form of key K.
cut at the end with notches or wards somewhat similar to those shown by Fig. 6. in
such positions and depths, that when the key K is inserted in the slot hole G.
between the guide plates H. and pressure applied to the end, all the levers are
actuated on the fulcrum pin the requisite distance for the ends at D' to clear the hook
catch or notch F. when the compressed spring S₁ raises the end of hook until the
notch F. is some distance clear of the levers at D'.
On opening the lock by inserting in the slot as described a key K. having its
notches or wards properly cut to suit the levers, by the time the ends at D¹ are moved
clear of the bottom notch F. the projections J. at the top of the levers are in such
position as to be clear of the hook, so that the latter may be withdrawn; but
should any of the notches or wards in the end of a key not be cut to correspond
with the levers so that all are operated the same distance by the key, one or more
of the levers will be moved too far before all the ends at D₁ are clear of the notch F.
therefore those levers that are moved more than the necessary distance for allowing
the end B of hook to be withdrawn from the lock case will come in contact with
the top notch L, thereby preventing the withdrawal of the hook.
As a means of further security against the possibility of opening a lock of this
construction except by a key made to correspond with the interior, I mount within
the lock caso a bell crank lever M. a fulcrum pin N, and joint or pivot to one arm
of the lever a number of pins P. which pass through holes bored in the guide
plates H.
On the insertion of a key in the slot between the guide plates H. with its end
cut to correspond with the levers D. unless there are corresponding holes bored
through the key K. as shown by Fig. 7. to allow the pins P to pass through.
The levers D. cannot operate the lever M. therefore the lock remains secure; but
if the holes through the key correspond with the pins and the end of the key with
the respective levers, then the levers D. can be actuated the necessary distance for
disengaging with the lock hook B. so that it can be withdrawn.
My improvement is also applicable to locks suitable for securing sliding windows
and the like; in the drawings Fig. 8. represents a view of the interior of a lock
suitable for this purpose. Fig. 9. a view of one side and Fig. 10 a view of the
other side of the lock.
In locks of this class, I mount a series of levers D. in a manner as before
described, each lever having a catch R. at one end; the lock bolt T in this case
is made to slide in the direction of its length, and is held secure when "shot"
or the end protruding beyond the face of the lock as shown, by the catches R.
engaging with a corresponding catch formed on the lock bolt T. When in this
position the lock bolt T. cannot be withdrawn except by the aid of a key, which
must be inserted in the slot G. between the guide plates H. and the end made to
correspond with the respective levers D. but should the end not correspond, the
top end of one or some of the levers D. at U. will project some distance into the
space Y. and thereby prevent the withdrawal of the lock bolt T. but when the key
is made to correspond with the levers, the lock bolt may be withdrawn by pulling
at the knob Z. and when withdrawn by pushing at the knob Z. the lock bolt is
"shot" or made to protrude without the aid of a key.

page_text: Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. Padlocks having a jointed hook B. with a curved end B₁ in which are formed
two notches F and L. combined with a series of levers D operated by the insertion
of a key in the manner described.
2. Locks in which are combined a series of levers D with a bell crank lever M.
having a number of pins P. jointed thereto, all operating substantially in the
manner described and shown.
3. A straight lock bolt T. combined with a series of levers D operated by the
insertion of a key for releasing the lock constructed substantially in the manner
shown and herein before set forth.
