lid, ftuffing-boxes, &c. by bringing the 
removable parts of each to come in imme- 
diate contact with one another. 3. and 4. 
The «wo next improvements relate to the 
conftru€tion and circular motion of the 
valves, the two uppermoft being inverted, 
and the valve-rods are made: to pafs 
through refervoirs of o:}, or other liquid 
matter, which effectually prevents the air 
from infinuating itfelf into the engine. 
5. The next principle is a new method of 
conneéting the pifton-rod to the parallel- 
motion. 6. And the laft relates to the 
con‘truStion of fire-places, by which the 
finoke acifing from the fire 1s confumed, 
and made part of the fuel. 
Tt would be impoffible to give any ac- 
curate idea of the feveral pasticulars of 
this invention, without the affittance of a 
plate, we muft therefore content ourfelves 
with the above recital of the advantages 
prepoted by the Patentee.

MR. GEORGE BODLEY’S (EXETER), PA- 
‘TENT for @ PORTABLE STOVE or 
KITCHEN for the PURPOSE of dreffing 
VICTUALS. a 
THE object of this patent is, we pre- 
fume, to fave as much as poflible the ex- 
pence of fuel. The whole ftove, which 
coniifis of three principal parts, an oven, 
a fire-place, and appurienances; and a 
fountain or warm clofet is made of caft 
or wrought iron plaies, properly taftened 
together with {crews or rive's, except the 
fides and bottom of the fire-place and afh- 
hole, which are compofed of bricks fet in 
mortar, loam, &c. The fire-place is in 
the middle, between the oven and warm- 
clofet. While the ftove is in ufe, the fire 
is inclofed by an iron door, fo that the 
fmoke and heat mult neceflarily pats 
through a funnel, which afcending clofe to 
one fide of the oven, is carried round the 
other three fides, under the afh hole and 
‘hot-clofer, and then aicends again by the 
State of Public Affairs in April, 1802. 
[May 1, 
outer fide of the clofet into a chimneys 
which conveys it into the open air. 
The top of the apparatus, which Mr. 
Bodiey calls the mantle, is a flat iron 
plate, and, from its conftant heat, when 
the ftove is at work, is capable of broiling, 
boiling, ftewing, &c, 
Objervation.— This kitchen feems very 
well calculated to anfwer its profefied end, 
but why it is defignated as portable we are 
at fome lofs to underftand; if the iron 
plates are thin, and the ttove fet up in the 
open air, the weil-known conducting 
power of the metal would diffipate a great 
part of the heat ; if very thick, the weight 
of the materials would render it unfit to 
be carried from place to place, a property 
which is naturally included in a portable 
machine. ‘A remark of this kind ftruck 
us very forcibly when giving an account 
of Mr. Walker’s portable ftove—See 
Monthly Magazine, vol. xil., p, 336.

MR. J. LEWIs’s (OLD-STREET, MID-= 
DLESEX), for 2 METHOD of PREVENT- 
ING ACCIDENTS by @ HORSE or HORSES 
drawing @ CaRRIAGe OY CARRIAGES. 
Bymeans of rings fitted to the harnefs,and 
bolts adapted to them, the horfe or horfes, 
are faftened with a chain to the carriage ; 
from the part of the carriage to which the 
chain is fixed proceeds a handle to the 
place moft convenient to be laid hold of by 
the driver, who can inftantly difengage the 
horfe from the ciiaife. The fame preffure. 
which fets the horfe at liberty, in cafe of 
a two wheel carriage, throws out two 
legs, one before and another behind, fo 
that the chaife fill keeps its level. And 
that the rider may be in no danger of fal- 
ling forward by the fudden ftopping of 
the carriage, each of the legs has a wheel 5 
thus the motion wil) be gradually retarded. 
Mr. Lewis*s invention is applicable .to 
curriclés and other carriages, the principle 
of whichis explained in the patent with @ 
number of drawings.
