(the Conunissioner), and .the Principal Officers of Bill '
Majesty's Dock Yard, ,Portsmouth, have given . the Patentee
permission to publish the following Statement of Facts relative
to his PATENT DETECTOit• LACK; namely, That hay
mg, by order of the Honourable Navy Board, lately supplied
a considerable number of his Patent Detector Locks for the
use of the Portsmouth Dock -lard, and being informed that
there was a Convict, on board one' of the prison-ShipS at this
port, who was notorious for picking Locks,. (being by profes-
sion a Lock Maker, and • who has, till recently„ for eeveral
years ban chiefly employed in picking and repairing Locks M.
London), the Patentee requested the iavour of Commissibner
the 'Honourable Sir GeOrge Carey to send for this man, that he
might exercise his skill in attempting to pick his Lock ; and
the Cummissioner having been pleased to acquiesce in this' re-
queet, the man was sent for accordingly, and ono of Chubb'e Pa- ',",;
tent Locks was submitted to his inspectain, at the Storekeeper s ~..
Office, in the presence of several of the Principal Officers ; when,
after a 'careful. exatnination, he said, " lie 'thought he could
Tick or open it with false instruments." He was therefore fur..
Aished' with files; and all the tools he stated to be necessary to
prepare theinstruments fur his .purpose ; and was directed to
give notice to the storekeeper when he should be ready to •
'make the trial,- thr the., promotion of which a Reward of
FiVe Pound*' was_,promitted him if he succeeded. In-about
avec • 'mks atter this time, he sent to say that he was
ready ;_ and, a time being, fixed on fur the .purpose, lie coin-
, menced his operations in endeavour irig to pick one of the Locks,
in the presence of the Principal Officers •of the Dock-yard;
but lie could not succeed. He • then stated, " that his failure
was in consequence of his instruments not exactly fitting the
Lock."' To remove this impediment, the Patentee offered to • •
sup Ply him with some blank keys, which should tit two of the , ;
Locks, in order to his making another trial ; these were fur-
nished accordingly, together with a. Lock exactly the same in
principle and in kind as those he had been trying, so that be.
might examine its construction, and make himself waster of
its principle. Shortly after he made another attempt to pick ' •
two Of the Locks, in the presence of the Honourable Sir
George Grey, and the Principal Officers of the. Dock-Yard :
his success in this attempt was not better than the first ; but
he overlifted the Detector of each Lock. Sir George Grey then '
asked him, what he would do in this case, supposing he had
been making an attempt on such a Lock, with an intent to coin-
mit a robbery ? lie said, " I would
,go no more to the Lock,
ever would set a watch and catch me. ' He still thought, how-
ever, that, by a further alteration of the instruments he could
yet succeed ; more time was therefore given him, and every
facility 'afforded him. Some time afterwards he again'repeated
his ettorts, in the presence of the same Gentlemen ; but having,
in his previous experiments, overlifted the Detectors, he could
not by any means disengage them ; this was done for him seve-
ral times with the Keys, belonging to the Locks ; but, as often
'as they were regulated, on every successive trial he detected
them again ; till at laSt he gave them up, saying, " That he
'bad used his utmost ability in his repeated attempts, and could
not succeed : that, these Locks were the must secure he bad ever
met widi,''und that he did not think it possible for any man to
- pick or open them with any false instruments whatever.
The Patentee of the above Lock, in making the following
observations, disclaims any intention of depreciating the merits
of oilier Locks, by describingg, their defects, or demonstrating
their insecurity: but trusts the Detector Lock will entitle hint
'to a share In the attention and patronage of the Public; as it
possesses, in a much higher degree than any' other, the four
principal requisites of a good Lock; viz. SECURI T I', SIM-
PLICITY, STRENGTH, and DURABILITY. Its SE-
CUR ITV, particularly, is increased beyond calculation, by an
improvement, which not only renders It impassible to be .picked
or opened by ally false instruments, but also detects the first
attempt to Open it ; thereby preventing those repeated efforts,
to which even the best Locks hitherto invented are exposed. In
these Locks, the combinations admit of so great variety, that
millions of them may be made, and yet one Key shall not pass
any two Locks ; and the Detector renders that variety infinite;
• lei the instaut that one or more of the tumblers are lifted beyond
'the place where the bolt is at liberty to pass, it overlifts the 001.0
tector, Which then hooks the tail of the bolt, preventing it from
passing, and thus gives incalculable additional security, (as well
as immediate notice, the first time the true key is put into it to
. ' open it, that un attempt has been made to pick it,) anti render*
all farther attempts useless; it being impossible to discover the
first combination, to disengage the Detecter or the second, to
remove the bolt ; and nothiog but the true key can either re.
- lease the Detector from its grasp on the bolt, or open the Lock.
In reference to its DURAIt ILIT V, it is not liable to be in-
jured by constant use in any length of time ; this hits been as-
., cerrained, by an Iron-rim Lock having been attached to a
Steam-Engine in the Dock-yard, Portsmouth (to try the effect
Of friction), by which it was locked and unlocked upwards of
fotir hundred and sixty thousand times,' without receiving the
least injury. The .STRENQT/1. of its . parts, and the SIM-
PLICITY of its construction, are such, that no False Key,
Or other Instrument, introduced into it for the purpose of open-
in g it, can (without. very great violence) injure it.
