Patentee, he finds, that as good leather 
may be made by this mode of tanning 
from fhavings, faw-duft, and chips, con- 
taining the tanning principle, particularly 
of oak, as from bark.—See an account of 
another Patent, in which faw-duft is ufed

jor @ MACHINE #0 GRIND BARK and 
other SUBSTANCES. 
This machine is, we are informed, cal- 
culated to produce the article of bark in 
the beft poffible ftate for tanners, fufti- 
ciently foft and fmall, with none of that 
fine duft caufed by friGtion, fo prejudicial 
to the procefs of tanning ; and the whole 
expence of a machine, which will laft fora 
great number of years, may be faved by 
the grinding of about one hundred tons of 
bark, without taking into confideration 
the rifque and expence of drying bark by 
fire, which is never recurred to by thofe 
who make ufe of this machine. 
The mills may be made of any fize, and 
grind any quantity of bark, by applying 
an adequate power: and they may be 
worked by water, wind, fteam, horfes, or 
even by manual labour. 
, This patent extends to grinding any 
other fubftance befides bark, and to an ap- 
paratus for raifing jiquors, and conveying 
them from one place, veflel, or vat, to 
another ; fo that no ‘man is obliged to 
dip or pump the liquor, or. handle the 
leather, as has hitherto been done. 
It may be applied to any tan-yard 
‘already planted ; to breweries ; andto many 
other ufleful purpofes.

Sor his INVENTION Of certain IMPROVE- 
MENTS 77 the APPaRATUs for, and 
mode of DISTILLERY, DRYING COF- 
FEE, and SUGAR. 
The improvements in diflilling confit, 
firft, in applying fteam to produce the 
heat required for diftillation, and adapting 
an apparatus for that {pecific purpofe ; 
and, fecondly, in varying the confiruétion 
and difpofition of common ftills, when fire 
alone is to be employed. 
In the procefs of diftillation, fteam is 
_ conveyed through proper tubes, either into 
the matter intended for diftillation, or 
through it, or wholly or partially round, 
or beneath it, and in contact with the ex- 
ternal fubftance of the ftill or veffel in 
_ which the matter is contained, or in any 
of thofe methods combined: that of in- 
troducing the fteam wholly and totally in-

to the body of the liquid to he diftilled,' 
fo as to be mingled therewith, being the 
moft effeétual and advantageous. 
‘The liquid being thus heated by the ac- 
tion or contaét of fteam, the fubfequent 
parts of the procefs proceed in the fame 
way as acommon diftillation over a fire. 
The parts effential to the fyftem of 
diftillation by fteam may be omitted, and 
then the apparatus will be applicable to 
the common mode of diftillery by fire 
alone, which conftitutes the fecond pare 
of the improvement, and confifts in making 
the roof of the ftill a medium of condenfa- 
tion, and applying a channel beneath that 
roof to conduét the liquid arifing frona 
the condenfation into the ultimate con- 
denfer. 
The mode of drying coffee and fugar 
confifis in expofing thofe fubftances to the 
action of air, raifed to a neceflary degree 
of heat, by paffing over, or in contaék 
with, a body of heated team. Tf, there- 
fore, any receptacle, admitting and dif- 
charging occafionally the external air, be 
allotted for drying coffee and fugar, and 
that receptacle heated by the accefs of 
fteam, fo that none of the fteam fhall come’ 
in contact with either of thofe fubftances ; 
that conftruction of an apparatus will pro- 
duce the effeét defcribed, and is claimed 
by Mr. Wyatt as his invention. 
This apparatus may be applied to the 
drying of other fubftances, {uch as grain, 
unpowder, &c.
