CHUBB'S PAlitil7V-1-ih:r.r.ECl'Olt LOCK.'

T.
/1E; lion. Sir GEO:.-GREY,
(the Commissioner), and the Principal Officers of Ills
Majesty's Dock Yard, Portsmouth, have given the Patentee
permission to publish the following ,Statement of Facts relative
to his PATENT DETECTOR LOCK; namely, That hay.
ing„hy order of the Honourable Navy Board, lately supplied
a considerable; number of his Patent Detector Locks for the
use of the Portsmouth Dock Yard, and being informed 'that
there was a Convict On board one of the prison-ships' at this.
,port, who was 'notorious fb picking Locks, (being by profes-
sion: a Lock Maker, and who has, till recently,' for several
years been chiefly employed in picking and repairing Locks in'
'Loudon);. the Patentee requested the favour of Commissioner
the Honourable Sir George Urey to send fur this man, that he
might exercise skill; in attempting to pick his Le& ; and .
the Commissioner having been pleased to acquiesce in this- re-
quest, the Man was sent tor accordingly, and one of Chubb's Pa-
tent Locks was submitted to his inspection, at the Storekeeper's
Office; in the presence OfieVeral of the Principal Officers ; when,
lifter a careful examination, he said, " he thought be could.
pick or open it with false instruments." He was thereforcfur-
: rushed with files, and all the tools he stated to be necessary to'
prepare the instruments tbr his purpose; and was directed to
give-notice to the Storekeeper when 'he should be 'ready to
make the trial, for the promotion of which a Reward of
Five Mninds wait:proised hint if lie succeeded. • 'ln about
three, w(icks after this' time, ho sent to say that he was
ready ; and, a time being fixed on fur the purpose; he coin-
minced his operations in endeavonting to pick etre of the Locks,
in the presence of the . Principal Officers of' the Dock-vaid;
but he could not succeed. 'lle then stated, ‘• that his (allure
was' inconsequence of his instruments not exactly fitting the
Lock:" To remove this impediment, the Patentee'offered to
supply him with some blank keys, which should tit two of the
ir 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
Plight examine its construction, and tasks himiele master of
its principle. Shortly after hinfide another attempt to pick
two of tne Locks, the presende 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 overlitled the Detector of each hock. Sir Georgelltcy then
asked him, what he would do in this case, supposing he had
been making an attempt on ouch a,,Loek, with ao intent to com-
mit a robbery P De said, " I would go no more: to the Lock,
ever would set a watch and catch me." He still thought, Ilea.-
ever, that, by a further alteration of the histruments.he; etiuld
yet succeed ; more time was therefore given hint, and eve:•y
facility afforded him: Some time afterwards be again repeated
his effort., in the presence of the same 'Gentlemen'; but having,
in his previous experiments, overlifted the Detectors lie 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 pp,. saying, That lie
bad used his utmost ability in his repeated attempts, and could
not succeed : that these Locks were the most secure he bad ever
met with, and that he did not. think it possible for any man to
pick or open them with any false instruments whatever.
Pie Patentee of the above Lock, in making die ffilloWing
observations, disclaims any intention of depreciating the merits_
of other Locks, by describini; their defects, or demonstrating*
their insecurity :. but trusts the Detector Lock will entitle him
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. SECURITY, SIM-
PLICITY, STRENGTH, and DURABILITY. Its SE.
CURITY, particularly, is increased beyond calculation, by an
improvement, which not only renders it impossible to be picked
or opened by any. 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 ;
for the instant that one or more of the tumblers are lifted beyond
the place where the bolt is at liberty to pass, it overlifts the De-
tector,, which then books 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 'spot into it to
open it, that an attempt has been made to pick it,) and renders
all farther attempts useless; it being impossible to discover the
first combination, to disengage the Detector, or the second, to
remove the bolt ; and nothing but the true key can either re.
lease the Detector from Its grasp on the bolt, or open the Lock.
In reference to its DURABILITY, it is not liable to be in.
jared by constant use in any length of time; this has been as.
eertained, by an Iron-rim Lotk 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
four hundred and sixty thousand times, without ,receiving the
least injury. The STRENGTH of its parts, and the SIM-
PLICITY of its construction tire such, that no False Key,
or other Instrument, introduced into it for the purpose ofopen.
ing it, can (without very great violence) injure it. ,
The Patent Detector Locks, of every aisle, and for all the
uses to which Locks can be applied, may be had of the Paten
tee, CHARLES CHUBB, Portsea.
