Locks.
CHARLES MCGUIRE BATE Capt. R.E. 36 Eardley Crescent Earl's Court
London do hereby declare the nature of this invention to be as follows:-
My invention relates to the combination of a lock with a thin plate of any suitable
material having barbs catches or points which being inserted into the crevice between
a drawer and its case or a door and its jamb the said barbs catches or points will
prevent the plate being withdrawn. The lock which is fastened or attached to this
plate by a bolt hinge or any suitable device pivots or turns on the plate in front of
the drawer or door the bolt of the lock engages in the plate and prevents it being
turned back. The lock or bolt in this position prevents the drawer or door from
being opened and until the lock bolt is turned back with the key allowing the lock
itself to be turned on its pivot or hinge or removed entirely the drawer or door
cannot be opened. The barbs catches or points may be removeable.
Dated this 24th day of June 1890.

Locks.
I, Captain CHARLES MCGUIRE BATE, R.E., of 36 Eardley Crescent, Earl's
Court Road, London, 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 :—
My invention is designed to provide an improved lock or fastening device which
can be temporarily employed in combination with a drawer, door or the like, to
prevent the opening of the same by unauthorized persons.
In carrying my said invention into practice I provide a casing to which is hinged
or jointed a thin plate having one or more barbs, catches, or points which, when
the said plate is inserted into the crevice between a drawer and its case, or a door
and its jamb or the like, will engage in the woodwork and prevent the withdrawal
of the said plate while the drawer, door or the like is closed. The said casing is
provided with lock-mechanism comprising a bolt, catch, lever or other suitable
device for securing the said casing at right angles, or approximately at right
angles to the said plate, and thus preventing the opening of the said drawer
or door.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a front elevation partly in vertical section illustrating one form of my
improved lock or fastening device, a portion of the casing being removed.
Figure 2 is a vertical section on the line xx, Figure 1.
Figure 3 is a vertical section showing a portion of a table and drawer with my
lock or fastening device applied thereto,
Figure 4 is a side elevation.
Figure 5 a vertical central section, and
Figure 6 a similar view to Figure 5 showing slight modifications of my invention
hereinafter described.
Like letters indicate corresponding parts throughout the drawing.
A is a plate having one or more barbs or teeth A¹, or other suitable points or
projections. The plate A is connected by a hinge joint A2, A3, to a casing B
077

page_text: somewhat resembling that of an ordinary padlock, so that when the said casing B
is moved or adjusted into line with the said plate the under surface of the said
casing B will be flush or in the same plane with the under surface of the plate.
C is a bolt, catch, or lever pivoted at C¹ to the casing B. C2 is an extension of the
said bolt catch or lever C, so arranged that, when the plate A is at right angles, or
approximately at right angles to the casing B the said extension will enter a hole,
notch or recess A' formed in the eye A2, in which it will be held by a spring D
one extremity of which is secured to the casing B and the other extremity whereof
engages with an extension C³ of the said bolt catch or lever C.
B' is a key-hole formed in the casing B, and B2 is a pin firmly secured to the
rear wall of the said casing so that it will enter the barrel of the key. To unlock
or unfasten the device, the key (which may be of any ordinary and suitable
construction) is inserted into the key-hole B and turned (as indicated in dotted
lines in Figure 1) until the bit thereof engages with the extension C³ of the bolt
catch or lever C and moves the latter so as to compress the spring D and disengage
the extension C2 from the notch or recess A'.
In Figure 3 I have shown my improved lock or fastening device applied to a
drawer and locked or secured so as to prevent the opening of the said drawer by
unauthorized persons. When the bolt, catch, or lever C is disengaged from the
notch A and the casing B is raised or moved into the position shown in dotted lines
in the said figure, the drawer can be pulled out as usual.
The point or points A¹ are preferably made flexible so as to enable the plate A
to be inserted into the crevice between the drawer and its case whilst the said
drawer is closed.
Figure 4 illustrates a slight modification of my invention wherein I provide a
boss or projection B³ upon the rear wall of the casing B. This boss or projection B³
engages with the front surface of the drawer or other object when the casing B is
moved down, and forms a fulcrum by means of which the plate A is drawn slightly
forward (before the parts are locked or secured together) thereby causing the point
or points A¹ to engage firmly in the wood work and preventing the fraudulent
removal of the fastening device by means of a knife-blade or otherwise.
Figure 5 illustrates another modification of my invention wherein the eye A' is
firmly secured to or formed on a pin or bolt A' and the casing B is pivoted to the
latter so as to be capable of turning or rotating thereon to enable the said casing
(when the device is in use) to be moved in line with the crevice between the drawer
and its case or across or at right angles thereto. A is a notch or recess formed in
the pin or bolt A', in which notch the extension C³ on the catch or lever C is
adapted to engage so as to lock or secure the said casing B in the latter
position.
In Figure 6 I have shown a further modification wherein the extension C' is
arranged to extend through the casing B and (when the device is placed in position
in the crevice between a drawer and its casing) project into the path of the said
drawer.
Although I have hereinbefore described and illustrated my improved lock or
fastening device as applied to a drawer, it is obvious that it is also advantageously
applicable to doors or the like. Any other suitable means may be employed for
locking or securing the hereinbefore mentioned plate at right angles or approximately
at right angles to the casing, and for enabling the device to be unlocked or unfastened
by means of a key. The improved lock may, if desired, be so constructed that, when
the casing is turned at a right angle to the plate, the key must be inserted and
turned to fasten the lock.
The points or projections upon the above mentioned plate are, in some instances,
made removable, thus enabling the said points to be readily replaced in case of
damage or wear. Instead of the said points or projections, or in combination
therewith, I sometimes provide one or more holes for enabling the said plate to be
secured in position to the table, drawer-case or other surface by means of one or
more screws, nails or the like.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. A lock or fastening device wherein a casing containing the lock-mechanism
is hinged or jointed to a plate provided with one or more teeth, points or projections,
and is adapted to be secured at a suitable angle to the said plate, for the purposes
above specified.
Second. A lock or fastening device consisting of a plate having one or more
teeth, points or projections and connected by a hinge-joint or by a pivot-pin to
a suitable casing, and lock-mechanism arranged within the said casing and
comprising a bolt, catch or lever adapted to enter a notch in an eye formed on the
said plate, or in the said pivot-pin, for the purposes above specified.
Third. The improved lock or fastening device constructed as above described with
reference to either of the forms or modifications illustrated in the accompanying
drawing, for the purposes specified.
