NEW PATENTS LATELY ENROLLED. _ 
Sse 
MR. THOMAS WELLS'S (ERDINGTON, Wak- 
~ WICKSHIRE), for an wuxproved Method 
of maknig and constructing Barrel- 
cocks and Water-cocks, whereby Leak- 
age, and the Stuckey o» Setting-fast of 
the Key or Plug, are prevented. 
et tare merits of this invention do not 
depend on the metal used in the 
construction of the cogks, but in the 
form of that part of the cOck which con- 
tains the plug or key, and which is call- 
ed the barrel, so that it cannot leak, nor 
suffer any liquer to pass through, except 
when the key is tarned for the purpose. 
This is accomplished by grooves that are 
made in the inside of the barrel of about 
4-8th of an inch in depth, and filling up 
these grooves with leather, hat, or any 
thing else of a similar nature, which will 
absorb the wet. ‘The number or direc- 
tion of the grooves is not material, 
—e ; 
MR. RICHARD SCANTLEBURY’S(REDRUTH, 
CORNWALL). for a Machine, by which 
he counterbalunces the Weight of any 
Column of Water, to be lifted by any 
Steam or Water Engine, or other Ma~~ 
chinery, either worked by Animals or 
Men. 
“ My invention,” says the patentee, 
is founded on the principle of the in- 
clined plane; thatis, I make an inclined 
_plane of wood, cast iron, or wroughtiron, 
or of any other fit materials, and of a 
convenient length, breadth, and _ thick- 
ness; to the centre of which I fix pinions, 
that it may turn alternately, or incline at. 
each end, as many degrees below its ho- 
rizontal, or centre level, as the nature of 
the machine mayrequire. On this plane 
{ place a travelier or car, so called by 
me, which is about half the whole length 
of the plane, with a weight or weights 
fixed on one or both its ends, which 
weight or weights, when moved, rolled, 
or carried, by wheel-work, from the cen- 
tre of the plane towards either end, will 
cause the plane to sink, or be depressed, 
to a certain degree of inclination below 
its centre level, and so vice versd. 
MR. WILLIAM PROCTOR’s (SHEFFIELD), 
for improved Methoes of raising or sup- 
plying Tubes or Lamps with Oil, so as 
ia remove the Shade of the Vessel con- 
taining the Oil. - 
Mr. Proctos takes a tube of brass, 
plated metal, or silver, or any other me-~ 
tal tube, drawn or bored; which tube 
sliall be so true- as to admit a plug, or 
kind of sticks. 
piston of leather, cork, or any other elas- 
tic or tight-fitting substance, to contain 
the oil upon it asa piston, which shall 
be so constructed, as to either ascend the 
tube, called the. candle part (or. suffer 
the tube or candle part, to move, either 
up or down, over the said plug, or pis- 
ton), for the purposes of raising or forcing 
the oil, so as to ascend to the upper part © 
of the tube, or candle appearance of the 
machine. The machine, er candle-lamp, 
may be applied to one or more lights, im 
one instrument or machine, or to the 
working part of the machine, so as to 
lubricate it, or prevent wearing of the 
parts by friction. And the above ma- 
chine for lights is intended to wear a si- 
milar appearance to common mould. or 
wax candles, mounted or fitted in any- 
The body of the candle- 
sticks may contain the screw of either 
male or female -for the perposes of being 
‘attached to the candle pert, or contain- 
ing the oil ; 1n such case the candle part 
must act as counter or contrary screw to 
that of the budy of the stick, and they 
must fit each other, so as to give the me- 
chanical motion, or if, without the spi- 
ral screw, the- ascent of the piston, or 
‘ descent of the candle passing up or down 
each other through plain tubes, vertically, 
or .artificially spiral, either with or with- 
out springs or collars to steady their moe 
tion.—QObserve to dress the lamp with oil 
and cotton, and unscrew the top of the 
candle, ;

MR. JOHN WARREN’s (POOLE), for an Ap- 
paratus to prevent Chimneys from Smek- 
ing, and to extinguish Hires in Grates 
and Stoves, without making any Dust - 
or Smoke, injurious to the Room or fur- 
nuUres. 
This apparatus has two objects ; first, 
to cause a continual current of the smoke 
until its. exitin the air, and to disperse it 
without any return into the chimney; 
and, secondly, to extinguish fires in 
grates and stoves, &c, without, making: 
any dust or smoke, injurious to the room 
or furniture. It consists of two parts— 
First, A frame to be placed at the top of — 
the chimney, which not only causes the - 
smoke to pass.into the open air without 
any lodgement, but excludes the weather 
from having any immediate access to the _ 
chimney. Secondly, A.plate at the bot- 
tom of the chimney, to be fixed in a’ 
fraine in the breast of the chimney, and 
to move in grooves from the nmiantle to 
the
