centre of the flue, through the breast of 
the chimney to the outside in any direc- 
tion, either on the right or left side, er in 
the centre of the fire-place, as the situa- 
tion of the chimney may require, and of 
‘ny depth’ from four to twelve inches, 
according as the diameter of the wheels 
may require; and of any leneth, accord- 
ing to the optional number of wheels. 
The advantages will farther appear in a 
double jack, 
eentre of the breast of the chimney, and 
extends to the right and left hand 5; as in 
the old way three bevil gear whieels are 
required, but in this way one wheel only 
is fixed in the middle of the spindle, 
which runs to the right and left, and 
working in and with those in the narrow 
box, and will answer the end of the three 
bevil gear wheels, placed in the old way; 
avd to each end of which may be added 
a chain-wheel. The boxes, eases, or 
bodies, are supplied with plate covers, 
and screwed down or fastened to the 
‘boxes, cases, or bodies, by means? of 
screws, screwed into the edge of the 
boxes, cases or bodies, or other lke fas- 
tening, and each cover has a small hinge 
at or near the cham-wheels on the out- 
side of the. breast of the chimney, by 
which means oil, or any substitute for 
oil, may be introduced, as occasion may 
require, without ascending the chimney. 
The boxes, cases, bodies or covers, are 
made of cast iron, or any other metal, 
being first made in wood, wider at the 
- top than the bottom, in order to give 
_euse to the founder in moulding. Wher 
“and when cast-iron ones cannot be es 
eured, then make them of sheet iron, or 
eopper, or other proper metal.

{HART-STYREET, BLOGMSBURY,). for a 
ceriain Animal Substance, and ! Washed

sume; whereby the said 1 Substance beconkes 
applicable us. Sas! ‘tute for Horse end 
ether Hair, now used for the stifling 
of Cushions, Mattresses, Carriages, 
‘Sofas, Chairs, &c. 
The said article or substitute for borse- - 
buir is manufactured of the nair or cvat. 
of hogs (not of the brist!es or mane ot the 
hoe, but of the-hair of its body ingeneral); 
. long hair of large hogs is the best for the 
purpose, bnt even that of pigs may be 
- made use of. After killing the hog, the 
hair is to be scraped off as at present rt 
is; then washed and cleansed -aiid thrown 
into lime water, where it may remain 
froin one to two days, Though the in 
New Patents os enrolled. 
which comes out in the: 
other fit material 
[Sept 1, 
merging in lime water is not absolutely 
necessary, it is nevertheless desirable, 
as thereby every fleshy substance is de- 
stroyed, and putrcfaction completel 
prevented. It is then washed in cold 
water, and twisted into.a cord of about 
the thickness of a goose quill, which cord 
is forced into a tin, glass, or other tube, 
whule it is twisted ; the tube to be about 
three quarters of au inch im diameter, 
and from fifteen to thirty, or more inches 
in length, though the lengtiris immaterial. 
This cord will read lily coil itself round in 
the inside, and a stick should occasionally 
be introduced to furce it quite ‘ught. 
When full, these tubes must be corked 
up close ae both ends; and when a suf-: 
ficient number of tubes are filled, they 
are to be placed in a copper of boiling 
water, where they should continue for 
two hours, the water boiling the while. 
The hair is then taken out of the tubes, 
and left to cool in solid pieces; these are. 
afterwards unpicked, when the hair will 
be quite curly. It is then loosely thrown 
into large earthen pans, with fine dry 
sand-at the bottem, and a layer of dry 
saud is sifted on every layer of hair, till 
the pans are filled ; they are then tied: 
over with brown paper, ‘i put into a 
het oven, where they,may so remain for 
three or four hours. ‘The heat must 
not be suticient to burn the brown 
paper, but nearly so, After the sand is 
quite cold, it is passed through a sieve, 
and the hair will-be tound fit for use, 
having obtained a good curl and fine 
elastic power, being also perfectly clean 
and incapable of engendering ay ver~ 
min, 
N.%.. Asmall, wheel, or other machine, 
commonly used tor twisting, may also be 
used for twisting the hair together, to put it 
into tubes; either in this case, or when twisted 
with the Gngers, the cords so twisted need 
not be long. ‘The hair should be damp to be 
twisted.
