Mr. JOHN Parry, of Chatham, has 
invented a ftand to fupport two and three 
flageolets, and can perform folos, duetts, 
and trios, with great eafe and pleafure. 
New Patents lately enrolled, 
557 
In point of fweetnefs and foftnels of tone 
his performance exceeds any thing of the 
kind. He intends to publifh a full de. 
{cription of the ftand, and inftruétions ° 
how a perfon may play upon two or three 
flageolets at one time. 
NEW PATENTS LATELY ENROLLED. 
MR. W. H. LASSALE’S (BRISTOL), for 
Improvements on Soap. 
HE nature of this invention is thus 
defcribed by the Patentee: “I take 
any quantity of aluminous earth as can be 
obtained of confiderable purity in the na- 
tive ftate, or otherwife, and purify it, if 
neediul, by mechanical or chemical means, 
I pulverize the faid earth, and mix it care- 
fully with ftrong alkaline ley, in fufficient 
quantity to render the whole imperfeatly 
fluid. I boil the faid mixture with con- 
ftant @irring, until the mafs hath acquired 
a f{mooth uniform appearance. In the 
mean time I prepare in another boiler a 
quantity of foap, hot, fluid, and nearly 
in the finifhed ftate, amounting to about 
three times the weight of the alumiyous 
earth, and I pour the hot mixture, or 
compound of earth and foap-lees, into the 
nearly-finifhed foap, and unite the whole 
together by ftirring and boiling, until 
the fame hath obtained a confiftence pro- 
per for conveying the article into frames, 
there to be cooled for fale. 
MR. J. DELAFONS (THREADNEEDLE- 
STREET), for his Invention of a marine 
Alarum Chronometer, for afcertaining 
the Time of a Ship’s Log line running 
out, the Time of the Watches on Ship- 
board, and other ufeful Purpofes. 
This chronometer is conttruéted for 
afcertaining the time of the fhip’s log-line 
running out, and is a fubétitute for the 
half and quarter minute-glaffes ufed at 
fea. The great wheel of this inftruntent 
has four pins or racket teeth faftened at a 
proper diltance from the centre: the ar- 
bor which paffes through the plates, and 
carries the hand, having the end, or fome 
part of this arbor or work fixed thereto, 
propelled forward by the main-fpring in 
the barrel. The arbor has acollar, &c 
faftened to it, on which is put the {pring 
and click: and the click having a tail or 
pin at the end, which paffing by the pin 
,or arch, is drawn out of the ratchet.— 
This click and difcharge may be.made in 
different ways, as is defcribed by means 
of drawings in the {pecification, to which 
d{pring. 
we muft refer our readers for farther ine 
formation on the fubject. 
When thefe machines are wanted for. 
other purpofes, fuch as regulating the 
time of the watches kept at fea, or to 
awake any one at a given time, or for re- 
gulating the time for culinary purpofes, 
then the great wheel may turn any num-— 
ber of wheels, initead of the f{cape-wheel 
only, to multiply the time of the machine 
going: thofe made for pocket alarums go 
twelve hours, thofe for culinary purpofes 
fhorter fpaces of time, according to the 
purpofes for which they are intended to be 
applied. The numbers for the teeth of 
the wheels and pinions are calculated the 
fame as watch-work. Where much ac- 
curacy isnot required, a train of wheels 
and a fly are fubftituted, or a {crew-wheel 
and worm; thefe and other altefations 
are made as occafion requires. 
The machines may be eafly made by 
means of a weight inftead of the main- 
fpring. ‘The power inay be given to the 
faid machines by a {pring fimilar to a gun- 
The machines may be made of 
various metals, hard wood, ivory, bone, 
or fimilar fubftances, but metal is efteem- 
ed the be& by Mr. Dtlafons. To render 
the nautical machines impervious to water, 
they are {crewed in, and varioufly affixed 
with oiled leather, or otherwife, and have 
a wooden or-metal cap within a wooden 
or metal box, with a handle for conve-- 
nient holding, but they may be made in 
various forms to the fame effect: they 
may be niade alfo to pull by a chain or 
{tring, orto pufhin a manner fimilarto a 
repeating watch. The face ‘of the ma- 
chines fhould be divided according to the 
ufe they are intended to be applied to, and 
are fet by turning the hand to the time re- 
quired to be known or determined. 
MR. J. B. DENIZE’s (SOMER’S TOWN), 
jor anew Mode of procuring a greater 
Quantity of refinous, bituminous, and 
oily Subftances from various Articles. 
The theory upon which this invention 
is founded confifts in converting all the 
fubftances of the mineral, vegetabie, and 
nat animal
