NEW PATENTS 
MR. GEORGE PENTON’S (NEW-STREET-, 
SQUARE) for an IMPROVEMENT iz 
ARGASND’S LAMP. 
R. Penton’s improvement confifts in 
a new method of raifing and lower- 
ing the cotton wick, an operation which is 
ulually performed by a rack and pinion, or 
wire, and is attended with this inconveni- 
ence, that asthe cotton burns away,therack 
or wire, employed to raifethe wick, remains 
above ee: The means invented 
to remove this defeét, are by the applica- 
tion of a chain and pulley, varioufly-con- 
trived, inftead of the wire, or rack and pi- 
nion—and which may be thus defcrib- 
ed: 
A cylindric tube contains the ring to 
which the cotton wick is faftened : it has 
a flit on one fide to foffer the wick-holder 
to move up and down by means of. little 
chains: one end of each chain is fattened 
to the ring of the wick-holder, and the 
other ends in the groove of the pulley, fo 
fituated as, when moved round, it will 
raife or lower the wick the full length re- 
quired. The pulley is fixed on a {mall 
arm of metal, which is projested from the 
cylinder fo as to admit of the pulley and 
chain behind it to work freely. 
On the axis of the pulley a button is 
fixed, by the turning of which the chains 
move over two pivots or rollers, fixed near 
the top cf the tube, and on a pivot or rol- 
ler projecting from a ring fixed on the in- 
fide of the tube at the bottom. By this 
means the wick is raifed or lowered at_ 
pleafure, by turning the button with the 
thumb and finger. 
The fame effe& may be produced by 
means of a fingle chain, the weight of the 
Cotton-holder being fufficient to carry it- 
felf down. Catgut, thread, or any other 
flexible material, may be ufed inftead of a 
chain. pes

LATELY ENROLLED. 
MR. JAMES THOMSON’S (EDINBURGH) 
for certain IMPROVEMENTS in banging 
BELLS, WINDOW-CURTAINS, WIN- 
Dow and other BLINDS, Gc. 
The principle of this invention confifts 
in fubftituting a balance or lever, to 
anfwer inftead of fprings. Without the 
aid of figures, which are attached to this 
{pecification, it would be in vain to at. 
tempt a minute defcription of Mr. Thom- 
fov’s improvements. We are however in. 
formed, that during thirty years conftant 
practice, he has endeavoured to improve 
the art of bell-hanging: he never liked 
the common mode of making the machi- 
nery perform by virtue of a fpring or 
{prings, the power of which being fo un- 
certain, as to the ftrength to be applied 
to every fituation or weight of work to 
be done; their liability to break, and 
lofing their power after being fome time 
in ufe, led Mr. Thomf{on to contrive fome- 
thing more fimple and lefs liable to go 
wrong: and he fays, that ‘* After confi- 
derable ftudy and expence, I think I have 
attained the end (as far as poffible, on a 
new principle, which will be the means of 
introducing that fine or eafy motion in the 
bell hanging art, fomuch wanted) by fub. 
ftituting a balance or lever, initead of 
{fprings; the powers of which are de‘cribed 
in the fpecification of the drawings of the 
apparatus; by which it will appear that 
the bell hanger has it in his power, toa 
very great nicety, to give juft the proper 
power to whatever work may be required 
to be done, and that pover not liable to 
go wrong, cr fail.”” ers" 
Remark.—Notwithftanding this flatter- 
ing account, as given hy the p2tentce, we 
have confiderable doubts how far this in- 
vention will prove {uperior to the art af 
of bell-hanging by means of fprings, 
This bufineis, when well executed, is not
