PROVISIONAL SPECIFICATION.
Improved Alarm Locking Apparatus.
I JAMES WILLIAM BLAKEY Engineer 190, Kirkstall Road Leeds Yorkshire
do hereby declare the nature of this invention to be as follows:-
My invention consists first of two plates of suitable material and shape with
projecting pieces, some to be used as grooves and others as studs for springs
and others as joints for a catch and others for a bell and bell-arm, the whole to
form when together a box suitable to hold the apparatus, and when applied to doors
or the front side of drawers this box also forms the handle.
Inside this box I place a spindle or some suitable arrangement for supporting a
number of rocking pieces and to these rocking pieces are attached levers formed in
shape that they may be easily manipulated by the fingers when the lock is on the
outside of drawers, doors, etc.
On each rocking piece rests a bolt.
These bolts are tapered at the lower end, so that its end can rest on either side
of the rocking piece. By turning some of the bolts around with their points to the
opposite side of the rocking piece they are raised above the level of the rest. On
the top of these bolts I arrange a plate to rest on the bolts, this plate is tapered at
the back and reduced at the front and of suitable shape at the ends so that if the
proper bolts fail to be withdrawn, it will come in contact with a catch or projecting
piece and release the bell-arm or make the connection required for an electric-
alarm.
The plate that rests on the bolts will require to be made less than the width of
the box holding the bolts, so that it can slide backwards or forwards on the top of
the bolts and also that it may come in contact with the projection or bell arm
catch. The above apparatus is fixed say to the front of a drawer. Now to the
object in which the drawer moves (immediately over the before named apparatus)
I fix another plate that as on its front side a piece tapered on its front edge and
operates in or upon the plate that rests on the bolts.
Where the lock is applied to doors the levers will require to be made so that
they can be operated from either side in some cases.
I wish it to be understood that allthough I have had granted to me a Patent
No. 2002-1885 for an apparatus for the locking of drawers described page 2
lines 27 to 39 and page 3 lines 1 to 34 which in operation is simular to this, yet the
parts of this invention as now arranged by me will enable me to fix it to almost
anything that locks of this character can be applied, whereas the one described in
the afore mentioned Specification and to the best of my knowledge all others of its
class were not adopted to the fronts of drawers or to doors etc., etc., but are limited
in their use to the back and inside of such drawers.
The apparatus now described may be also fixed inside and at the back of drawers,
and wires may be attached to run to the front and be at the bottom of or inside
such drawer and come through to the front and have a cover to form handle for
drawer and conceal the wires.
The rocking pieces will be a differant shape and the tapered end of bolts, in fact
it will only represent the old apparatus in so far that the setting of the lock is the
same, while the adaptation of and reconstruction of the several parts are such that
the lock is much stronger and more practical than the last and really a new
invention.
I may also make the apparatus so that it cannot be adjusted after being tampered
with excent by the intervention of a key.

page_text: I may also arrange a spring and wheels and suitable arrangements for a clock-
work alarm.

COMPLETE SPECIFICATION.
Improved Alarm Locking Apparatus.
I JAMES WILLIAM BLAKEY, 190 Kirkstall Road Leeds Yorkshire 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, reference being had to the accompanying sheet of drawings :—
Fig. 1 is a front view of box or handle to hold the apparatus.
Fig. 2 is a section through xx.
Fig. 3 is an elevation of F a plate with projecting pieces for purposes which I
will afterwards name.
Fig. 4 is a plan of G it is a plate with a T shaped grove for Figure 3 to work in
as I will afterwards describe.
Fig. 5 is a back view of Figure 1 showing the rocking pieces with levers or
finger-plates attached.
Figure 6 is a front view of a box of a different shape to Figure 1 its use I will
afterwards describe.
Fig. 7 is a side view of catch to be used along with Figure 6 for alarm
apparatus.
Fig. 8 is a plan of the rocking piece A with lever and finger plate attached
showing piece cut away to allow for its moving backwards and forwards without
interfereing with the finger-plate next thereto.
Figure 9 is a plan of the rocking piece B with the lever or finger plate attached
showing the exact construction thereof.
Fig. 1 J is an elevation of box to hold apparatus, and the plate G shown near the
top of drawing is a loose piece with a T shaped grove as shown in the Figure 4.
K is a rod for supporting the rocking pieces. From the line immediately shown
above the letter G, is the part which is fixed to the drawer, while the piece H with
lugs attached thereto (and holes for screws or bolts therein) is made fast to the
counter, and in the front of the piece H is a keyhole R for the insertion of a key
to adjust the piece F when required.
Fig. 2 is a sectional view of Fig. 1 showing the rocking piece (with lever and
finger plate attached which moves freely on the spindle K the back of C is cut
away and a small projection left to support the spring L the other end of spring L
is supported by a projection on the plate M as will be seen most plainly.
Immediately on the top of the rocking piece C is a vertical bolt D its lower end
being tapered as will be seen, and on the bolt D rests the loose piece F the top end
of F is tapered at the back on the top end and passes through the wide part of the
grove G (as shown in Fig. 4) and into the box H on moving the finger plate C the
top end of the rocking piece will move towards the plate M the spring L will be
compressed and the bolt D will drop down as will also the loose piece F the top
end of the loose piece F will then be below the top edge of the plate G, thus the
drawer would open.
On releasing the lever or rocking piece C the spring would
expand and push up the bolt D and also the loose plate F and the top end of the
loose plate F would pass up through the groove G but to close the drawer the
lever C need not be operated as will be seen the back edge of the loose piece F is
tapered of, and on coming in contact with the rounded projecting edge on the plate

page_text: or box H, it will push down the loose plate F as also the bolt D and cause the
rocking piece to compress the spring L until the top of the loose piece F has passed
clear of the rounded edge on the top plate or box H when the spring L would
expand and push the rocking C along with the bolt D and loose piece F into their
original position.
Immediately behind the bolt D is a dotted outline of another bolt E with its
tapered end at the opposite side to the one on the rocking piece C, it will be seen
that while the before metioned operation or moving of the rocking piece C resulted
in the bolt D moving downwards this bolt E would move upwards and retain the
loose piece F with its top end through the grove in the slot of plate G and thus on
pulling the drawer the loose plate F would slide back and its narrow part would
slide into the narrow grove (see Fig. 4) in the plate G and the projecting ends of
the top of the loose piece F (see Fig. 3) would prevent its dropping down whichever
levers might be operated thus the drawer would be locked.
To adjust the lock the drawer would require to be pushed back and a key inserted
through the keyhole R and on giving the key a half turn it would push the loose
piece F back again to its original position, it will be seen that complicated races
may be placed within the plate H to render more difficult the picking of or
readjusting of the loose piece F.
It will be seen on refferring to Fig. 5 that the rocking piece C has but one
bearing on the spindle K while the rocking pieces A and B have each two bearings,
it will also be seen on refferring to Fig. 8 plan of A how it is shaped and cut away
to allow it to work without it coming in contact with the one next thereto.
I may crank the levers so that the rocking pieces may be placed on one side of
the handle J as in Fig. 6 P and in the part Q I may arrange a clockwork alarm
movement so that the loose plate F would move the catch N Fig. 7 on its centre
and thus release the lever O from the hook on catch N and it the lever O would
move on its centre and allow a clockwork alarm to be released and thus sound an
alarm.
To attach an electric alarm I should attach one pole to the plate M and the
other pole immediately behind the narrow slot in the plate G and on the loose
piece F sliding back in the narrow grove the circuit would be complete. The bell
may be attached to the drawer or in any required or suitable position.
Although I have shown five rocking pieces in the drawings I may use more or
less as may be required.
I
may also make the rocking pieces the width of the finger plates and the tapered
bolts of corresponding width thus the top part of the box or handle J would be of
corresponding width to the bottom part, and the levers of the rocking pieces would
not then need to be cranked or yet require two bearings.
In making the rocking pieces the width of the finger plates I should require the
bottom of plate F Fig. 3 to be made a corresponding width as also the ends of the
plate G.
The plate G has a piece S fastened to the back so that it may slide down the
back of the plate M. To reset the lock it is necessary to lift off the plate G as
also the loose plate F it will be observed that this cannot be done except when the
drawer is open.
It will be seen that in Fig. 1 holes are shown wherewith to fix the lock but in
Fig. 2 these holes are left out to render the drawing more clear and distinct.
While the drawings show the lock to be fixed on the face of drawers it will be
easily understood that by making the lower end of the rocking piece or finger plate
further away from the spindle K and the lower part of box J made to stand further
out the lock might be sunk into the face of the drawer.
And should it be required to fix the lock within and at the back of any drawer
by cutting away the finger plates or rocking pieces and drilling holes therein by
means of wires along the bottom of and to the front of such drawers into a box
forming a handle to conceal the wires.

page_text: 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 arrangement and adaptation of the several and respective parts as
herein described together forming an interchangeable lock for fixing to the front
of drawers.
2. The rocking pieces with levers and finger plates attached.
3. The loose piece F the plate G with T shaped slot therein.
4. The application of an interchangeable lock to the fronts of drawers manipu-
lated in the manner as herein described.
5. The tapered bolts for and as described.
6. The plate or box H with keyhole therein and the manner of adjustment of
the loose piece F by means of a key.
7. The manner of making an electric connection for the purpose as herein
described.
