Improvements in Rim-locks, Applicable also to Dead-locks, Gate-
locks, Night-latches, and the like.
I, WILLIAM STURMEY, of Clemson Street, Willenhall, Staffordshire, Lock
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention consists of improvements in rim-locks, dead-locks, gate-locks, night-
latches and the like whereby such locks and latches can be used either for right hand
or for left hand doors or gates without any of the parts of the mechanism of such locks
or latches having to be altered or changed.
I will first describe my invention as applied to a rim-lock having a single tumbler.
I make the bottom of the key-hole similar to the top so as to admit the key either
with its pin or stem part upwards or downwards, and I form an extension on the
bolt below the key-hole having a notch or notches for the key to engage in similar to
the notch or notches in that part of the bolt which is above the key-hole. The bolt
can thus be operated either when the key is inserted in the key-hole in the ordinary
manner or when the pin or stem of the key is inserted in the lower part of the key-
hole. I also provide a tumbler below the key-hole similar to the tumbler above the
key-hole except that it does not engage with the bolt. The tumbler above the key-
hole has a downwardly projecting arm formed with it near where it is pivotted to
the lock case, and the tumbler below the key-hole has a similar arm projecting
upwards. When the key is inserted in the key-hole in the ordinary manner that is to
say with its pin or stem uppermost the upper tumbler and the bolt are operated in
the ordinary manner and when the key is inserted in the key-hole with its pin or stem
part in the bottom of the key-hole and turned, the bottom tumbler is pressed down by
the key which causes the end of its said upwardly projecting arm to move forwards
and to carry with it the end of the downwardly projecting arm of the upper tumbler
thereby raising the upper tumbler and allowing the bolt to be moved either
backwards or forwards by the key as the case may be. Each end of the key-hole has
a separate and distinct set of wards so that whether the lock is used for right or left
hand it is a perfectly complete lock. My invention can be similarly applied to a
tumbler lock having several tumblers or levers.

tumbler rim-lock, and on each of the levers I form a downwardly projecting arm
similar to the arm above described as being formed on the tumbler of a tumbler rim-
lock. Below the key-hole I provide a lever or levers corresponding with the lever or
levers above the key-hole and each having an upwardly projecting arm.

page_text: Improvements in Rim-locks, Applicable also to Dead-locks, Gate-
locks, Night-latches, and the like.
I, WILLIAM STURMEY, of Clemson Street, Willenhall, Staffordshire, 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 consists of improvements in rim-locks, dead-locks, gate-locks, night-
latches and the like whereby such locks and latches can be used either for right hand
or for left hand doors or gates without any of the parts of the mechanism of such
locks or latches having to be altered or changed.
I will first describe my invention as applied to a rim-lock or a dead-lock having a
single tumbler. I make the bottom of the key-hole similar to the top so as to admit
the key either with its pin or stem part upwards or downwards, and I form an
extension on the bolt below the key-hole having a noich or notches for the key to
engage in similar to the notch or notches in that part of the bolt which is above the
key-hole. The bolt can thus be operated either when the key is inserted in the key-
hole in the ordinary manner or when the pin or stem of the key is inserted in the
lower part of the key-hole. I also provide a tumbler below the key-hole similar to
the tumbler above the key-hole except that it does not engage with the bolt. The
tumbler above the key-hole has a downwardly projecting arm formed with it near
where it is pivotted to the lock case, and the tumbler below the key-hole has a
similar arm projecting upwards. When the key is inserted in the key-hole in the
ordinary manner that is to say with its pin or stem uppermost the upper tumbler and
the bolt are operated in the ordinary manner, and when the key is inserted in the key-
hole with its pin or stem part in the bottom of the key-hole and turned, the bottom
tumbler is pressed down by the key which causes the end of its said upwardly
projecting arm to move forwards and to carry with it the end of the downwardly
projecting arm of the upper tumbler thereby raising the upper tumbler and allowing
the bolt to be moved either backwards or forwards by the key as the case may be.
Each end of the key-hole has a separate and distinct set of wards so that whether the
lock is used for right or left hand it is a perfectly complete lock. My invention can
be similarly applied to a tumbler lock having several tumblers.
On the accompanying drawings Fig. 1 represents a tumbler dead-lock embodying
my invention the top plate being removed to shew the interior, the key being inserted
in the upper part of the key-hole to operate the tumbler and bolt in the usual manner;
Fig. 2 is a cross sectional elevation of the same shewing the parts in the same position
as represented by Fig. 1; Figs. 3 and 4 represent the same lock as Figs. 1 and 2 but
the pin or stem is inserted in the lower part of the key-hole to operate the tumbler
and bolt through the extra tumbler and extension of the bolt below the key-hole:

page_text: Figs. 5, 6 and 7 represent respectively in elevation and in plan separate views of the
bolt, upper tumbler and lower tumbler of the lock shewn by Figs. 1, 2, 3 and 4.
Fig. 7 represents the bridge plate and wards of the same separately.
Similar letters of reference indicate similar parts in all the Figures.
A is the lock casing, B is the key-hole having the bottom 61 made similar to the
top so as to admit the pin or stem of the key C either upwards or downwards,
Dis the bridge plate, d' are the wards for the key when inserted with its pin in the
lower part of the key-hole (see Fig. 3) and are the wards for the key when
inserted with its pin or stem in the upper part of the key-hole (see Fig. 1). E is the
bolt projecting through the casing A in the ordinary_manner and having the usual
notch e above the key-hole for the key to engage in, E2 is the extended part of the
holt below the key-hole provided with the notch e2 similar to the notch e¹. F' is
the ordinary tumbler (except that it has the downwardly projecting arm f¹) pivotted
on the ping and having the usual side projection / which is by the spring i caused to
engage in the notches e, e in the bolt to maintain the bolt in its locked and unlocked
positions in the ordinary manner. Fis the tumbler below the key-hole which does
not engage with the bolt and which is free to turn on the pin g2 and 3 is its upwardly
projecting arm long enough to engage with the downwardly projecting arm f¹ on
the tumbler F. The slotted hole e³ in the bolt E¹ fits upon a projecting pin a¹ on the
lock casing which forms a guide for the bolt in the usual manner.
When the key is inserted in the upper part 2 of the key-hole, that is in the ordinary
manner (see Figs. 1 and 2) and turned, the upper tumbler F is raised to free the bolt
and the bolt can be moved backwards or forwards by the key engaging with the
notch e¹ in the ordinary manner; and when (as shewn by Figs. 3 and 4) the key is
inserted in the key-hole with its pin or stem part in the bottom of the key-hole and
turned, the bottom tumbler F2 is pressed down by the key and in turning on its pin g²
the end of its upwardly projecting arm moves forward and carries with it the end
of the downwardly projecting arm f¹ of the upper tumbler F thus raising the upper
tumbler F and allowing the bolt to be shot either backwards or forwards as the
case may be by the key entering the notch e³.
It will be seen that as the mechanism of the lock can be operated either when the pin
of the key is inserted in the top of the key-hole or when it is inserted in the bottom of
the key-hole, the lock can be used for either right or left hand by fixing the lock
either with the tumbler F¹ uppermost as shown or with the extra tumbler F³
uppermost.
Fig. 8 represents in front elevation, with the top plate removed, a tumbler rim-lock
embodying my invention and Fig. 9 is a cross sectional elevation of the same, the key
being inserted with its pin or stem in the upper end of the key-hole; Figs. 10 and 11
represent the same lock as Figs. 8 and 9 but the pin or stem of the key is inserted in
the lower end of the key-hole to operate the tumbler and bolt through the extra
tumbler and extension of the bolt below the key-hole; Fig. 12 represents in elevation
and in plan the bolt of the same separately.
In this lock the latch bar K, the latch lever L and the cam M for the knob spindle
are all of the usual form the latch bar L lying between tumbler F2 and the top
plate a. The key-hole B, bolt E' with its lower extension E2, the upper tumbler F¹
and the lower tumbler F are in this lock all constructed and arranged to operate
similarly to the corresponding parts of the lock liereinbefore described and illustrated
by Figs. 1, 2, 3, 4, 5, 6, 7 and 7*.
In applying my invention to a lever rim-lock or a lever dead-lock I make the key-
hole double and extend the bolt below the key-hole similarly as above described with
reference to a tumbler rim-lock and a tumbler dead-lock, and on each of the levers I
form a downwardly projecting arm similar to the arm above described as being formed
on the tumbler of a tumbler rim-lock or a tumbler dead-lock. Below the key-hole I
provide a lever or levers corresponding with the lever or levers above the key-hole
and each having an upwardly projecting arm. The said lever or levers below the
key-hole does or do not engage with the bolt but when the lever or levers below the
key-hole are depressed by turning the key the upwardly projecting arm or arms of

page_text: such lever or levers acts or act upon the downwardly projecting arm or arms of the
lever or levers above the key-hole and so frees or free the bolt and allow of its being
shot or withdrawn as desired.
Fig. 13 represents a lever rim-lock embodying my invention the top plate being
removed to shew the interior, the key being inserted in the upper part of the key-
hole to operate the levers and bolt in the usual manner; Fig. 14 is a cross sectional
elevation of the same shewing the parts in the same positions as represented by
Fig. 13 Figs. 15 and 16 represent the same lock as Figs. 13 and 14 but the pin or
stem of the key is inserted in the lower part of the key-hole to operate the levers and
bolt through the extra levers and extension of the bolt below the key-hole. Figs. 17, 18
and 19 represent respectively in elevation and in plan separate views of the bolt, one
of the upper levers and one of the lower levers of the lock shewn by Figs. 13, 14, 15
and 16. In this lock each of the four levers N1, N2, N3, N above the key-hole has a
downwardly projecting arm marked respectively n', n², n³, n' and below the key-holo
there are four extra levers M1, M2, M3, M4 corresponding with the levers above the
key-hole and turning on a pin and each having an upwardly projecting arm
marked respectively m¹, m², m³, m and engaging with the downwardly said projecting
arms of the levers above the key-hole. These levers M³, M³, M³ M* below the key-
hole do not engage with the bolt but when they are depressed by turning the key (as
shewn by Figs. 15 and 16) their upwardly projecting arms m³, m², m³, m³ respectively
act upon the downwardly projecting arms n', n², n³, n' of the levers above the key-
hole and thus free the bolt and allow of its being shot or withdrawn as desired when
the bit of the key enters the notch e2 on the lower extension of the bolt. When the
pin of the key is inserted in the upper end of the key-hole and turned the
levers N1, N2, N3 N are raised, and the bolt shot to or fro, in the usual manner.
This invention can be applied to lever or tumbler gate-locks, night-latches and the
like similarly as above described with reference respectively to lever or tumbler rim-
locks and dead-locks such alterations in the shape of the parts only being necessary as
will adapt the invention to the particular lock or latch to which it is applied.
I am aware that previous to this invention locks have been made with a double
ended key-hole and a bolt which can be operated by the key from either end of the
key-hole so that the lock would answer for either right or left hand but such bolts
have generally had two separate and distinct sets of tumbler or lever mechanism
operating separately from each other.
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 :
1st. In a tumbler rim-lock, dead-lock, gate-lock, night-latch or the like and in
combination with the double key-hole and the bolt arranged to be operated by
inserting the key at either end of the key-hole, a tumbler pivotally supported near
one end of the key-hole and having a projecting arm and engaging with the bolt in
its locked and unlocked positions respectively, and a corresponding tumbler pivotally
supported near the other end of the key-hole and having a projecting arm gearing
with the projecting arm of the first said tumbler so that at whichever end of the key-
hole the koy is inserted and turned the tumbler which engages with the bolt will
be disengaged therefrom substantially as berein before set forth.
2nd. In a tumbler rim-lock, dead-lock, gate-lock, night-latch or the like and in
combination with the double key-hole and the bolt arranged to be operated by
inserting the key at either end of the key-hole, a set of tumblers pivotally supported
near one end of the key-hole and each having a projecting arm and engaging with the
bolt in its locked and unlocked positions respectively, and a corresponding set of
tumblers pivotally supported near the other end of the key-hole and each having a
projecting arm gearing with the corresponding projecting arms of the first said
tumblers so that at whichever end of the key-hole the key is inserted and turned the
tumblers which engage with the bolt will be disengaged therefrom substantially as
herein before set forth.
3rd. In a tumbler rim-lock, dead-lock, gate-lock, night-latch or the like of the

page_text: kinds referred to in claims 1 and 2 and in combination with the double key-hole
thereof, a bridge D supported from the lock casing having a key-hole enlarged at
either end for the insertion of the pin of the key and two separate sets of wards d', d
for the purpose and substantially as set forth and illustrated by Figs. 1, 2, 3, 4 and 7*
and Figs. 8, 9, 10 and 11 of the accompanying drawings.
4th. In a lever rim-lock, dead-lock, gate-lock, night-latch or the like and in
combination with the double key-hole and the bolt arranged to be operated by
inserting the key at either end of the key-hole, a lever or a set of levers pivotally
supported near one end of the key-hole each having a projecting arm and engaging
with the bolt in its locked and unlocked positions respectively and a corresponding
lever or set of levers pivotally supported near the other end of the key-hole and cach
having a projecting arm gearing with a projecting arm of the corresponding first said
levers so that at whichever end of the key-hole the key is inserted and turned the
lever or set of levers which engage or engages with the bolt will be disengaged
therefrom substantially as set forth.
5th. The combination of the bolt E¹ having lower extension E2, the double ended
key-hole, the bridge plate D and wards, the pivotally supported tumbler F engaging
with the bolt and having the projecting arm ¹, and the pivotally supported
tumbler F having the projecting arm f2 these parts being connected and arranged
together for joint operation and use substantially as herein before set forth and
illustrated by Figs. 1, 2, 3, 4, 5, 6, 7 and 7* and by Figs. 8, 9, 10, 11 and 12 of the
accompanying drawings.
6th. The combination of the bolt E¹ having lower extension E, the double ended
key-hole, pivotally supported levers above the key-hole engaging with the bolt and
each having a downwardly projecting arm, and the pivotally supported levers below
the key-hole each having an upwardly projecting arm gearing with the downwardly
projecting arms of the levers above the key-hole, these parts being connected and
arranged together for joint operation substantially as hereinbefore described and
illustrated by Figs. 13, 14, 15, 16, 17, 18 and 19 of the accompanying drawings.
Dated this 6th day of December 1887.
