THOMAS DAWSON’s (JAMES STREET, 
LONG-ACRE) for a LAMP or LAN- 
THORN, upon an umproved CONSTRUC- 
TION. hie oi 
This is a carriage-lamp,and,like others, 
it can be made to any fhape or pattern. A 
deicription of a four-fided one will convey 
to the reader a proper idea of the jnvep- 
ticn. ‘Iwo fides are of courfe dark, with 
_ reflectors, the other two of glafs. Ac- 
cording te the old confirution, there were 
fliders before the glafs, which were the oc- 
cafion of feveral inconveniencies. Mr. 
Dawion, to prevent the neceflity of thefe, 
makes his lamp to confift of two parts, 
_namely, the lamp itfelf, anda cafe, the 
Jjatter is fixed to the carriage, and the 
former is eafily taken in and out, and 
being made exaétly fquare, in the day time 
the dark fides are outwards, which pre- 
vents any damage happening to the gla{s ; 
and at night the glafs is inftantly turned 
outwards, and candles or oil may be uled 
at difcretion ; another advantage is, that 
in cafe of any accident to the carriage 
by night, or of any thing loft, &c. the 
}amps may be taken very readily from the 
cafes, when they make admirable hand- 
lanthorns. ! “

Jor bis improved PLAN of MAKING, 
ADJUSTING, aud STAMPING, SCALE- 
WEIGHTS: 2 
The high fcale-weights, fuch as have 
been commonly ufed with’ handles, of one 
pound’ and upwards, are made folely of 
hard and durable metals, without any ad- 
dition of lead. The flat weights are ad- 
jufted and flamped, by attaching to them 
a piece of metal, harder than lead, yet 
capable of receiving the impreffion made 
by the ftamps, . sii oe 
New Patents lately enretlea.

Thehigh weights are caft in fand, er 
in a metallic mould, an opening being left 
in them of any form, of a luthcient deep- 
nefs for the purpefe, of adjulting, and its 
furface large enough to contain the Ramps; 
which opening is afterwards exatily 
filled with a piece of metal, to render the 
weight perfeétly conformable to the flan- 
dard. When the adjulting weight is tao 
heavy, its weight is diminifhed by filing 
off part of its bottom, or by giving it 
feet,in order to leflen its fize,without redu- 
cing its height ; or by placing below it, for 
the fame puypofe, a bit of rolled iran 
. more or lefs turned up at bothends. The 
metal ufed for adjufting and ftamping, 
is fixed by two iron pins, put into the 
~ body of the weight when it is caft, which 
are to be riveted on the outfide. In the 
flat weights the rivets go intirely through 
the weight itfelf. 
Although the adjufting weights may be 
made of any metal, or of compounded 
fubfances, yet Mr. Wilfon  preters 
wrought-iron or fteel ; the fubltitution of 
an indeftructible fubftance, in place of 
Jead, being intended to prevent any devia- 
tion from the ftandard by common wear, 
while every thing elfe is fo contrived as to 
render it impoffible to mutilate the weight, 
without putting it in the power of any 
one who examines it, merely by ocular 
in{peétion, to detect the fraud. The tops 
are made floping, that the duft may not 
lodge on them, and the edges are rounded 
off to prevent chipping.
