HADROT'S PATENT MODERATOR LAMP

Mr. Robert M. Walker introduced several of these ex-
cellent lamps, amongst which was one made transparent
in order to show its working principles. The invention,
he stated, was a French one ; and had been so successful
in that country that its originator had been induced to
protect it in England by letters patent. The ohjections
to lamps, when contrasted with gas or candles, have
hitherto been numerous, but the chief of these were here
removed. Instead of the absorbent powers of the wick
being the only means of conducting the oil to the flame,
a spiral spring, to which was attached a piston, was intro-
duced, which forced the oil, fountain like, over the top of
the burner ; the residue, being again deposited in the
original reservoir, where it could be, at will, brought under
the action of the pressure of the spiral spring by turning a
small handle, which raises the piston by a pinion wheel
and rack. The piston is so contrived that, while it allows
the oil to pass downwards, it will not permit of its ascen-
sion, except through the burner. From the pressure thus
attained, the article consumed is deposited in the base of
the lamp, and, therefore, no shadow is created from the
retort, as in other lamps. The invention is altogether
most simple and efficacious. The light is most brilliant ;
and the several lamps exhibited met with great approval
for their utility and elegance of design. The prices
are most moderate. It was stated that Mr. Allen, of
Parker-street, had introduced them into Liverpool.

NEW DETECTOR LOCK.

Mr. Cotterill, of Birmingham, then produced a beauti-
fully-worked specimen of his " patent climax detector
lock," which is very ingeniously constructed, defying the
skill of the most accomplished burglar, and the principle
and detail of which are totally different from and appa-
rently superior to anything heretofore introduced. We
have no doubt that Mr. Cotterill will be liberally sup-
ported by the public ; and we understand that the worthy
president of the society, who ought to be a good judge, has
given an order to the inventor for a quantity of these
articles. The principle consists in a cylindrical barrel,
containing a number of steel slides, which move in radi-
ating channels, in the face of the barrel, and are pressed
towards the centre by helical springs contained therein.
A circular groove is cut in the face of the barrel and of
the slides, so that when the slides are forced outwards by
the key a continuous circular channel is formed by the
coincidence of each of these with that in the barrel's face;
when the key is withdrawn, each of the slides is forced in
different degrees towards the centre, so that their solid
portions intercept the groove in the barrel, and in this
position the barrel is held fast by a fixed circular ring
fitting into the groove, and notched on its face so as to
embrace each of the slides. The key consists of a cylin-
drical stem, having a number of inclined grooves cut in
its circumference, agreeing with the number of the slides
in the lock ; these grooves are cut longitudinally in
the barrel of the key, and they all vary in depth, slope,
and the angle formed by their bottom with the axis of the
key. When the key is placed in the lock for the purpose
of opening it, the inclined bottom of each groove forces
out a slide until the openings in the latter coincide with
the notched ring, and the barrel may then be turned by
the key in either direction. Should an attempt be made
to open the 10. k with a false key, the slides are projected
too far and are retained in that position by spring catches
or detectors, which fall into the groove, so that the true
key cannot open the lock until by a peculiar backward
movement the detectors are disengaged. Any violent
application of an opening instrument or false key will not
affect the works injuriously, owing to the slides being
firmly fixed in deep grooves formed in the revolving bar-
rel, and secured down by a steel ring, which precludes
every approach to the movement by any other means than
the legitimate key, which, from its peculiar formation, it
is impossible to take a correct impression of an
advantage no other key possesses. The slides merely
move along the grooves, under cover, and return by the
pressure of the helical springs, which are equally distri-
buted around, and these having such a very slight amount
of duty to perform, are not liable to set or break, but sup-
posing such an improbable thing could occur, it would
not injure the action in• be slightest degree, as the secu-
rity of the lock rests solely on the exact distance the slides
are forced from the centre, not in their returning to any
particular place, consequently the security of the lock
must remain unimpaired even if the whole of the springs.
were damaged. Where the slightest friction occurs in
the works, a counter one has been provided, in order to,
prevent derangement ; in fact, this lock has treble the
strength and durability of any lock in the market, and
possesses none of the liabilities to get out of order. The
keys are cut by a newly-invented machine, which can be
varied whilst working to such an extent, that millions of
keys may be cut, and yet every one shall differ. The
locks are all made to the keys, which at once removes the
possibility of any but the legitimate keys opening them.
A vote of thanks was then moved to the respective ex-
hibitors, and the meeting separated.
