Improvements in or in connection with Locks or Locking Devices.
I, HENRY BIRKBECK of the firm of "Tongue & Birkbeck," Patent Agents,
34, Southampton Buildings, Chancery Lane, London, W.C. Fellow of the
Chartered Institute of Patent Agents, do hereby declare the nature of this invention
(a communication to me from abroad by Marcus Adler and Maier Berliner, both
Merchants of No. 30 Walker Street, in the City of New York, State of New
York, U.S.A.) to be as follows:-
This invention applies to that class of locking devices which are intended to
insure that certain preliminaries are performed as the fastening of windows and the
closing of water and gas cocks before the main key which may be an ordinary ward
key can be applied to a corresponding lock to secure the outer or main door on
leaving an apartment or building.
According to this invention a pin is provided separate from and independent of
the ordinary key which secures the main door which piu receives the several
sub locks and holds them upon itself. The key is retained in a stationary holder
during the day (or other time) and is released only by the introduction of the piu
after the several locking devices have been properly placed on the several window
fastenings water cocks etc. so that the pin is empty and can be thrust in the proper
hole in the holder.
After opening the place the next morning (or other time) the main door key
must be introduced into the holder before the pin can be liberated. Then the pin
is used to successively liberate and retain on itself the several locking devices or
sub locks strung thereon until it becomes time to again secure the parts when the
several locks are again placed on the several subordinate parts to secure them and
the empty pin is again thrust into the holder to liberate the main key.
The following is a description of what the communicators .consider to be
advantageous and suitable means of carrying out the invention.
The accompanying drawings form a part of this Specification
:-
Figure 1 is a front view of one of the main locks with the sub lock in place
nearly covering and concealing it.
Figure 2 is a section thereof on the line 2-2 in Fig. 1.
Figure 3 is an
edge view.

Figure 8 is a front view of the holder.
Figure 9 is a horizontal section thereof on the line 9-9 in Figure 8.
Figure 10 is a vertical section on the line 10-10 in Figure 9.
Figure 11 shows the main lock properly applied to a cock for gas and for other
fluid as water or steam and with the sub lock removed allowing the cock to be
operated. The pin is in place to allow the sub lock to be applied or removed.
Figure 12 is an edge view of one of the sub locks. The remaining figures show
modifications.
Figure 13 is an elevation showing this invention applied to secure a screw valve.
Figure 14 is a horizontal section showing the invention applied to secure the
sashes of a window. The sub lock has been removed and the window sashes are free
to be raised or lowered.

page_text: Similar letters of reference indicate corresponding parts in all the figures where
they appear.
Referring to Figures 1 to 12 inclusive A A are parts as the levers of water cocks
which require to be secured.
M M are sub locks adapted to secure the parts A and having so little thickness
that a number can be strung upon a single pin C which is straight and equipped
with a series of shallow holes each aiding by means to be described farther on to
retain one of the sub locks M when the latter are strung thereon.
The key D may be of any desired size or form and adapted to operate in any
ordinary or suitable manner with any style of lock on the main door (not shown).
E is a stationary holder set in any conveniently accessible position and adapted
to receive either the pin C or the key D; but it will release only one at any one time
and only on the insertion of the other.. It incloses a lever G adapted to be operated
by the introduction of either the key D or the pin C to move a transverse slide H
and effect the liberation of the other. Thus when the main key is inserted the
slide H is engaged therewith and the pin C is liberated and may be withdrawn and
used. When at a later period the pin C is introduced it operates the lever G and
is engaged by the slide H and the key D is liberated and can be withdrawn
and used.
The pin C is provided with a longitudinal wing or spline C₁ and each sub lock M
is provided with a corresponding hole adapted to receive the slender cylindrical
body of the pin C and its wing C. This insures that it shall be held on the pin in
certain determined position. The pin is provided with a series of holes c¹ opposite
to the wing C¹ each of which holes when the sub locks are strung on the pin
receives an internal bolt or catch. from one of the sub locks.
The pin C has a conical or tapering point C².
Each main lock S contains two levers N N turning on centres n and connected
by one end to sliding bolt P subject to the force of a spiral spring Q and adapted
to protrude through the casing of the main lock and engage it with the sub lock M.
The levers N are operated in one direction by the springs Q and allow the
bolts P to be thrust out and to engage with corresponding holes in the sub lock.
These levers are operated in the opposite direction by the thrusting in of the pin C
which acts by its tapering end C2 on the proper ends of the levers N and withdraws
the bolts P in opposition to the force of the springs Q.
The casing S is notched as at s to receive a spur on the end of the handle A (sec
Figure 11) and the introduction of the sub lock into the main lock and the
protrusion of the bolts P of the latter by the withdrawal of the pin C leaves the
sub lock engaged with the main lock covering the end of the lever A and retaining
it until the attendant shall on the morning succeeding thrust the pin C again into
the sub lock and withdraw the bolts P. Then on removing the sub lock the
lever A is free and can be turned by the attendant into the required position to
supply the building until the reverse operation is effected at night and the sub lock
is again left engaged with the main lock again securing the lever of the cock.
The shank of the key D and also a proper point in the cylindrical portion of the
pin C is mortised as indicated by c to receive the proper end of the transverse
slide H.
It will be readily seen that such mortise should be of sufficient length to allow
the pin or key to complete its movement while the slide H remains engaged in
the mortise.
The small holes in the pin (see Fig. 6) receive each a small sliding bolt I from
any sub lock (see Figs. 5 and 7).
This bolt I is actuated by a spring J tending to urge it into engagement with
the hole c' in the pin C when the latter is inserted with the sub lock and thrust
through it and through the main lock on which it is to serve.
When a sub lock has been put in its place to properly secure the main lock of
the gas cock window or other part the attendant can liberate it by withdrawing the
bolt in opposition to the force of the spring J.

page_text: This is effected by thrusting inward on the pin K which acts against a lever L
turning on a centre 1. (See Figures 2, 5, and 7.) Then the bolt I may be
withdrawn and on taking away the pin C the sub lock will be left in place.
Modifications may be made in the details without departing from the principle or
sacrificing the advantages of the invention.
It is possible to vary the thickness of the sub locks correspondingly varying the
distance apart of the holes c' in the body of the pin C..
Figures 13 and 14 show modifications to which is attached some importance
Each shows the main lock made in two parts with provisions for inserting the
pin C in a hole formed half in each part. The two levers N each with its proper
bolt P and actuating spring Q are carried one in one part and the other in the
other part. In Figure 13 the one part is carried on the hand wheel which operates
a screw valve and the other part is correspondingly fitted on the stationary pipe.
In Fig. 14 the two parts of the main lock are carried on the two sashes of a
window.
It will be understood that the invention may be applied in other situations as the
valves of the steam heating apparatus the switch of the electric-lighting wires the
door of the safe and any other places which it is desired shall be properly taken:
care of before the place (of business or otherwise) is closed for the day or any
other period.

Improvements in or in connection with Locks or Locking Devices..
1, HENRY BIRKBECK of the firm of "Tongue & Birkbeck" Patent Agents,
34 Southampton Buildings, Chancery Lane, London, W.C. Fellow of the
Chartered Institute of Patent Agents, do hereby declare the nature of this inven-
tion (a communication to me from abroad by Marcus Adler and Maier Berliner,
both Merchants of No. 30 Walker Street, in the City of New York, State of New
York, U.S.A.) and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention applies to that class of locking devices which are intended to
insure that certain preliminaries are performed as the fastening of windows and
the closing of water and gas cocks before the main key which may be an
ordinary ward key can be applied to a corresponding lock to secure the outer

to be operated. The pin is in. place to allow the sub lock to be applied or
removed..
Figure 12 is an edge view of one of the sub locks. The remaining figures
show modifications.
Figure 13 is an elevation showing this invention applied to secure a screw
valve.
Figure 14 is a horizontal section showing the invention applied to secure the
sashes of a window. The sub lock has been removed and the window sashes
are free to be raised or lowered.
Similar letters of reference indicate corresponding parts in all the figures where
they appear.
Referring to Figures 1 to 12 inclusive A. A are parts as the levers of water cocks
which require to be secured.
M. M are sub locks adapted to secure the parts A and having so little thickness
that a number can be strung upon a single pin C which is straight and equipped
with a series of shallow holes each aiding by means to be described farther on to
retain one of the sub locks M when the latter are strung thercon.
The key D may be of any desired size or form and adapted to operate in any
ordinary or suitable manner with any style of lock on the main door (not shown).
E is a stationary holder set in any conveniently accessible position and adapted
to receive either the pin C or the key D but it will release only one at any one
time and only on the insertion of the other. It incloses a lever G adapted to be
operated by the introduction of either the key D or the pin C to move a transverse
slide H and effect the liberation of the other. Thus when the main key is inserted
the slide is engaged therewith and the pin C is liberated and may be with-
drawn and used. When at a later period the pin C is introduced it operates the
lever G and is engaged by the slide H and the key D is liberated and can be
withdrawn and used.
The pin C is provided with a longitudinal wing or spline C and each sub lock M
is provided with a corresponding hole adapted to receive the slender cylindrical
body of the pin C and its wing C. This insures that it shall be held on the pin in
certain determined position. The pin is provided with a series of holes c¹ opposite
to the wing C' each of which holes when the sub locks are strung on the pin
receives an internal bolt or catch from one of the sub locks.
The pin C has a conical or tapering point C
Each main lock S contains two levers N N turning on centres and connected
by one end to sliding bolt P subject to the force of a spiral spring and adapted
to protrude through the casing of the main lock and engage it with the sub lock M.
The levers N are operated in one direction by the springs Q and allow the bolts P
to be thrust out and to engage with. corresponding holes in the sub lock. These
levers are operated in the opposite direction by the thrusting in of the pin C which

page_text: acts by its tapering end C² on the proper ends of the levers N and withdraws the
bolts P in opposition to the force of the springs Q.
The casing S is notched as at s to receive a spur on the end of the handle A. (see
Figure 11) and the introduction of the sub lock into the main lock and the pro
trusion of the bolts P of the latter by the withdrawal of the pin C leaves the sub
lock engaged with the main lock covering the end of the lever A and retaining it
until the attendant shall on the morning succeeding thrust the pin C again into the
sub lock and withdraw the bolts P. Then on removing the sub lock the lever A. is
free and can be turned by the attendant into the required position to supply the
building until the reverse operation is effected at night and the sub lock is again
left engaged with the main lock again securing the lever of the cock.
The shank of the key D and also a proper point in the cylindrical portion of the
pin C is mortised as indicated by e to receive the proper end of the transverse
slide.El.
It will be readily seen that such mortise should be of sufficient length to allow
the pin or key to complete its movement while the slide H remains engaged in the
mortise.
The small holes c¹ in the pin (see Fig. 6) receive each a small sliding bolt I
from any sub lock (see Figs. 5 and 7).
This bolt I is actuated by a spring tending to urge it into engagement with.
the hole in the pin C when the latter is inserted with the sub lock and thrust
through it and through the main lock on which it is to serve.
When a sub lock has been put in its place to properly secure the main lock of
the gas cock window or other part the attendant can liberate it by withdrawing the
bolt I in opposition to the force of the spring J.
This is effected by thrusting inward on the pin K which acts against a lever L.
turning on a centre 1 (see Figures 2, 5 and 7). Then the bolt I may be withdrawn
and on taking away the pin C the sub lock will be left in place.
Modifications may be made in the details without departing from the principle or
sacrificing the advantages of the invention.
It is possible to vary the thickness of the sub locks correspondingly varying the
distance apart of the holes c¹ in the body of the pin C.
Figures 13 and 14 show modifications to which is attached some importance
Each shows the main lock made in two parts with provisions for inserting the
pin C in a hole formed half in each part. The two levers N cach with its proper
bolt P and actuating spring Q are carried one in one part and the other in the
other part.
In Figure 13 the one part is carried on the hand wheel which operates
a screw valve and the other part is correspondingly fitted on the stationary pipe.
In Figure 14 the two parts of the main lock are carried on the two sashes of a
window.
It will be understood that the invention may be applied in other situations as the
valves of the steam heating apparatus the switch of the electric-lighting wires the
door of the safe and any other places which it is desired shall be properly taken
care of before the place (of business or otherwise) is closed for the day or any other
period.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
•
1. The locking means described comprising a series of thin locks or sub locks M
and main locks Š the latter each equipped with means P for retaining a sub lock in
a main lock and with means I J carried in the sub lock for retaining it at another
period upon a pin C the whole adapted to serve in securing water gas windows etc.
in an apartment or building as herein specified.
2. The locking means described comprising a series of thin locks or sub locks M
and main locks S the latter each equipped with means P for retaining a sub lock
in a main lock and with means I J carried in the sub lock for retaining it at another

page_text: period upon a pin C in combination with the means K L in the main lock for
effecting the liberation of the sub lock from such pin when desired' arranged for
joint operation as herein specified.
3. In a locking system the holder E having two holes adapted to receive the
pin C and key D and means as the lever G and locking slide H for engaging
and liberating each one at a time as herein specified.
4. In a locking system the pin C. having the wings C' extending along one
side and holes c and c¹ and having a taper end C adapted to serve with the
levers G and slide H of a series of sub locks M and with a holder E and key D
