fcrew and lever regulate the exaét degree

Obfervation.— The great importance of 
this machine to multitudes of the human 
race, renders every improvement intereft- 
ing to the public : in this view we with 
fucce(s to the invention before us. To us 
it appears capable of aniwering the pur- 
poles dehgned by the patentee; and as it 
requires no under ftrap, there will be no 
rik of fri@tion, and of excoriating thofe 
parts which are frequently injured by 
truffes of the common conftruétion. The 
Jever mut be fhortened to render the in- 
vention more complete. 
MR. WILLIAM DOBSON’S (STRAND) for 
certainMethods, by Means of MACHINE- 
RY, aewer before applied for that Pur- 
pofe, of CHASING AWAY FLIES, and 
VENOMOUS INSECTS, calculated to 
promote the free Circulation of Air in. 
Rooms, and to difperfe ‘the offenfive 
Efiuvia and Steam arifi "6 trom Meat, 
Viands, Ge. 
The machine defcribed in this {pectfica- 
tion is denominated the ZEPHYR, and it 
-confift's of the following parts, viz. A.pil- 
Jar fupported by a moveable pedeftal ;,, at 
the top of which is a globe, vafe, urn, or 
flat circular box, for containing the move- 
ments, which are wound up by a key; and 
connected with thefe movements are arms, 
on which fails are drawn; the motion of 
thefe is to effect the purpofes mentioned 
in the title. 
The pillar confitts of cylindrical tubes 
of different diameters, the fmalleft is in- 
ferted, and flides into the larger, like thofe 
of a telefcope, by which means the fails 
may be fo altered as to a& either above 
the heads or before the faces of the com- 
pany,’ as may be moft agreeable, fo that 
the pillar is fixed or draws out, {crews 
out or winds up, and may be of one piece 
or many. 
The urn or box at the top of the pillar 
contains the power which gives motion to 
the machine ; it confifts of the ftrongeft 
and fimpleft clock, jack, and watch work, 
that cam be ufed. 
‘Fhe machines are of different kinds, 
and with powers fuited to the effe&t re- 
- quired to be produced. The arms-on 
which the fails are drawn confit of tubes 
fimilar to thofe which form the pillar, and 
are made to move horizontally or any other 
New Patents lately enrolled, , ibBS 
way ; they are jointed at the end, that the 
fails may be lifted up out of the way, or 
that the velocity of the machine may be 
increafed. The fails are made of any ma- 
terial and fhape, fuch as lawns, crapes, 
gauzes, and nettings, the lait feems moft 
appropriate to chafe away winged inle&ts 
in general. 
When the machine is wound up, and 
placed in its intended fituation, the motion 
of the fails propel the air in a circular 
current, which in a few feconds reaches to 
every part of the room, and the outer part 
of the circulation being repeatedly driven 
to the fides of the room, it rufhes along in 
the diregtion of the fails till it is forced 
out at the chimney, the ufual out-let of 
the air. :

MR. WILLIAM PLEES’S (CHELSEA) for 
certain Methods of manufatiuring Pa- 
PER for various Purpofes, and of apply- 
zug one of the faid Methods to Purpofes 
for which PaPérR bas never before becuz 
ufed. 
Mr, Plees claims, under this patent, the 
exclufive right to two inventions. The 
jirft is that of a paper manufactured of 
any of the various fubftances already 
Known to be veined, clouded, mottled or 
{peckled an. different colours, ‘by adding 
paper~ftuff, paper-fhavings, rags-of Imen, 
cotten, or filk, firaw, hay, chaff, tan, to- 
bacco; fauff, bran, bark, bronze, fpangles, 
frofts, foils, or any other fubftances ca- 
pable of being made to bed, fufficiently, 
into the ftuff which forms the ground. 
Thefe weins, cloads, &c. afte to be mixed 
with the ftuff, fo as to form one general 
ma{s previoully to the dipping ; and either 
cut or torn by hand, by the engine, 
or by any other machine more fuitable or 
convenient; or elle to be {prinkled or 
poured over the mould before dipping, or 
over the fheet before or after couching ; 
or received on the mould by» repeated 
dippings before couching ; or by couching 
two or more deliveries on each other. The 
fecond invention is for applying tie'above, 
and alfo any other defcription of paper 
capable of being rendered elaftic,; to the 
purpofes of leather, by tanning, currying, 
or drefiing them in any of, or all the va- . 
rious methods already known for finifhing 
leather from hides or fkins. The methods 
principally ufed, are by taking wool or 
woollen rags, either alone or mixed with 
thofe of linen, cotton, hemp, flax, or junk, 
the properties intended to be given being 
thofe of ftrength and elafticity,
