NEW PATENTS LATELY ENROLLED. 
EEE 
MR. WILLIAMS'S (CORNFILL), for,a Me-' 
thed of preserving the Equilibrium, 
and preventing ali kinds of Carriages 
Jjrom overturning. 
lee EAD of putting each pair of the 
wheels of the carriage upon one and 
the saine inflexible axis or framing, hav- 
ing extreme parts answering the pur- 
poses of an inflexible axis as is usually 
done, whereby the said wheels in eac h 
pair are made to preserve an unalterable 
position with regard to eacli other, is sub- 
stituted a pair of levers projecting hori- 
zontally on each side, in opposite direc- 
tions from the same part of the perch or 
middle bar, or framing made use of to 
connect the whiee!ls of and belonging to 
the said carriage, and at night angles to 
the line of traction. Each of the. levers 
is connected with the pe rch by means of 
a hinge, or strong joint in the shape ofa 
hinge, sd fixed that they shail be allowed 
to move in 4 vertical circle, or ap and 
down; and upon the extremities of the 
said levers the wheels are secured. The 
body of the carriage is supportedgon 
springs made to bear or act on the said 
levers; to which, in some cases, they are 
afiixed, and in_others the springs act with 
one end not ‘fastened or fixed, and then 
the body is connected with the framing 
beneath, by means of an upright bolt or 
pin, which leaves room for the pl ay of the 
body up and down. Other springs are 
also applied to support the fore and hind 
parts of the body, by causing the said 
springs to bear upon the perch or fram- 
ing of the carnage. In four-wheel car- 
riages, the back and front springs are not 
necessary, on may be used, if deemed 
preferable. The elfect of the levers and 
interposed springs is, that whenever an 
obstacle or cavity shall present itself to 
any one of the wheels, it will rise over 
or be depressed into the same, without 
producing the same disturbance in the 
equilibrium, or endanger the oversettmg 
of the carriage in the same degree as 
would happen in hke circumstances te 
carriages difierently constructed. 
MR. WILKINSON’S (BRADFORD), fur a new 
Method of making Pig or Cast Iron 
trom the Ore. 
This invention consists in making use 
of manganese, in addition to iron-stone, 
and other materials now used in making 
iron; and in certain proportions to be 
varied, according to the nature of the 
mater ials. a tg 
It would unquestionably have been 
more satisfactory to the public, if Mr, 
Wilkinson had stated not only the result 
of his experiments, but also the quantity 
of manganese used ‘in producing iron, 
which he asserts is equal to the best 
Swedish iron. .The discovery, which is 
assumed to be of great national advan- 
tage, should have been minutely detailed, 
in order that the public may hereafter 
derive the benefit which is held out by 
the patentee.
