IMPROVE- MENTS APPLICABLE TO BRAMAH AND OTHER LOCKS
Year: 1877

page_text: LETTERS PATENT to John Batson, of Brewer Street, Golden Square, in the
County of Middlesex, Fancy Cabinetmaker, for the Invention of "IMPROVE-
MENTS APPLICABLE TO BRAMAH AND OTHER LOCKS."
PROVISIONAL SPECIFICATION left by the said John Batson at the Office of
the Commissioners of Patents on the 8th September 1877.
JOHN BATSON, of Brewer Street, Golden Square, in the County of Middlesex,
Fancy Cabinetmaker. " IMPROVEMENTS APPLICABLE TO BRAMAH AND OTHER
Locks."
This Invention consists of improvements applied to locks, whereby the case to
which such lock is applied can be readily opened, and is specially applicable to
stationery cases, cigar cabinets, and such like, where it is required that the door fit
perfectly flush, and where a handle would be unsightly.
In carrying out my Invention I proceed as follows (taking as an example a
Bramah lock-To the upper face of the bolt of the lock I attach or secure a piece
of metal at right angles to the said bolt, and parallel to the nozzle, placed either
outside or inside of the nozzle. Around the portion of the lock where the keyhole
is situate I place a ring of metal, which on one side is hinged, and where hinged a
projection or knob is formed, and there is also formed a similar projection on the
other side of the ring to raise it by.
In using my Invention the key is applied and the bolt withdrawn. This brings
the projecting piece on the bolt under the portion of the nozzle before described
where hinged. The nozzle is then raised, and the projection or knob on the nozzle
presses against the projection on the bolt, which wholly withdraws the bolt, and at
the same time pulling the ring opens the lid of the case.
A modification of the above arrangements consists of hingeing the nozzle, so that
this will serve the purpose of the ring of metal above named. In this arrangement

page_text: the projection on the nozzle is formed inside, as also the projection on the lock, the
action being similar to that above described.
By placing the projections inside the lock is not interfered with, and the appearance
is the same as ordinary Bramah locks.
The above shows my Invention as applied to a Bramah lock, but it is evident it
is equally applicable to other kinds of locks.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Batson in the Great Seal Patent Office on the 8th March

JOHN BATSON, of Brewer Street, Golden Square, in the County of Middlesex,
Fancy Cabinetmaker. "IMPROVEMENTS APPLICABLE TO BRAMAH AND
LOCKS."
This Invention consists of improvements applied to locks, whereby the case to
which such lock is applied can be readily opened, and is specially applicable to
stationery cases, cigar cabinets, liqueur and dressing cases, and such like, where
it is required that the door fit perfectly flush, and where a handle would be
unsightly.
In carrying out my Invention I proceed as follows (taking as an example a
Bramah lock)-To the upper face of the bolt of the lock I attach or secure a piece
of metal at right angles to the said bolt, and parallel to the nozzle, placed either
outside or inside of the nozzle. Around the portion of the lock where the keyhole
is situate I place a ring of metal, which on one side is hinged, and where hinged a
projection or knob is formed, and there is also formed a similar projection on the
other side of the ring to raise it by.
In using my Invention the key is applied, and the bolt withdrawn; this brings
the projecting piece on the bolt under the portion of the nozzle before described
where hinged. The nozzle is then raised, aud the projection or knob on the nozzle
presses against the projection on the bolt, which wholly withdraws the bolt, and
at the same time pulling the ring opens the case.
A modification of the above arrangements consists of hingeing the nozzle, so that
this will serve the purpose of the ring of metal above named. In this arrangement
the projection on the nozzle is formed inside, as also the projection on the lock, the
action being similar to that above described. In some cases however the bolt is
withdrawn directly the nozzle or ring of metal before described is actuated.
By placing the projections inside, the lock in appearance is the same as ordinary
Bramah locks.
The above shows my Invention applied to a Bramah lock, but it is evident it is
equally applicable to other kinds of locks.
Having thus far described the nature of the said Invention, and incidentally
intimated in what manner the same is to be performed or carried out in practice, I
will now proceed (aided by the accompanying Drawings) to further and particularly
describe and ascertain in what manner the same is to be performed or carried out in
practice, that is to say :—

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 shows front view of my improvements, with the nozzle of the lock raised;
Fig. 2, section on line A, B, Figure 1.
In these Figures a is the bolt of the lock, to the upper face of which (at right
angles to the same) is secured or attached a piece of metal or projection (b) parallel
tothe nozzle, and which may either be placed inside or outside the nozzle, according
to the arrangement of the lock. The Figures show the projection inside. The
nozzle (c) of the lock is hinged as shown (or in some cases a ring of metal may be
used in place thereof, as before described), and is provided with a suitable ridge or
projection at the edge thereof to facilitate the raising of same.
The action is as follows:-The key being applied in the ordinary way, the bolt a is
withdrawn, and the projection b is thus brought under that portion (d) of the nozzle
c, where same is hinged, as shown in Fig. 2. The nozzle cis then raised, the part d
pressing against the projection b on the bolt a, by which action the bolt is wholly
withdrawn, and the door or lid to which the lock is fixed can be opened.
The projections being placed inside the lock (as shown in the Drawings) will not
in any way interfere with the action or appearance of the same, and it is evident
that the improvements herein-before described and set forth may be applied to any
other forms of locks besides Bramah locks, the Bramah lock being merely taken as
an example in illustrating the working of my Invention.
The bolt, as before described, may be withdrawn without the intervention of a
key, the lifting of the nozzle withdrawing the bolt.
Having now particularly described and ascertained the nature aud object of the
said Invention, and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the Invention of "Improvements Applicable
to Bramah and other Locks," substantially as the same is herein-before set forth and
described, wherein the arrangement of the nozzle and the projections, substantially
as and for the purposes set forth, are novel and peculiar features.
In witness whereof, I, the said John Batson, have hereunto set my hand and
seal, this Eighth day of March, in the year of our Lord One thousand eight
hundred and seventy-eight.
