the compofition of the yarn, in which this 
mode differs from any fuch now in ufe. 
To accomplith this, the fibres com- 
pofing the yarn are laid at various Jengths, 
according to the ratio of their relative po- 
fitions,in the yarn, or their refpective dif- 
tances from the centre of it. This is per- 
formed by a moveable machine, which by 
its‘ progreflion gives motion at the fame 
time to fpindles, or {pinning-hooks con- 
tained in it, thereby alfo giving a twift to 
the yarns to be {pun. 
The fpinner, inftead of walking back- 
wards in {pinning with the hemp, flax, or 
other article round him, remains ftationary, 
whilft the hemp or flax is laid at its whole 
length on a board, table, or other conve- 
nient fupport, in which is inferted a num- 
ber of upright pins, as in a tool or hatchel, 
fo as to. receive and fupport about half the 
Jength of the hemp or flax, or from the- 
thickelt part of the head of hemp or flax, 
to the end of the fibres farthett from the 
_ machine. The end of the article'to be 
fpun is held by the fpinner, and directed 
towards the machine, which is brought to. 
a convenient diftance, and the fpinner be- 
gins the operation by drawing fome fibres 
of the hemp, flax, or other article,’ and 
making them faft to one of the {pindles or 
fpinning-hooks. The fpinner has a cloth 
in one hand to hold and comprefs the yarn, 
and with the other hand he feeds the yarn 
from the hemp, &c. At this period mo- 
tion is given to the machine. is 
The machine defcribed is in a wocden 
frame, placed upon trueks, wheels, or 
rollers, and it has motion communicated to 
it by a band of any required length, aéted 
upon by man, horle, or by a mill or fteam 
engine, or by any other adequate power. 
This band is applied to a rigger, pulley,

or whirl, on the axis of a cylinder in the 
machine; round which cylinder are bands 
of lift,' cloth, or fome other flexible fub- 
ftance, and which bands give motion te 
the fpindles or {pinning-hooks in any re- 
quired number for twifting the yarn. The 
fpindles are placed either above or below 
the cylinder, and at right angles to it, or 
parallel to the motion of the machine. - 
The motion of the cylinders gives motion 
to the machine on its trucks, wheels, é&c. 
by other wheels, or by a rigger connected 
by a band, in order to give a progreffive 
motion to the machine, thereby. drawing 
the hemp, flax, &c. to any required length. 
This progreflive motion may be in any di 
rection, and it may be varied In any ratio 
or proportion to the motion of the fpindles 
by changing the wheels, or by different= 
fized grooves in the riggers; or the hefts 
cf the {picdles may be varied in thicknefs, 
according to the intended fize of yarn to be 
fpun, fo as to produce a proper twit. 
When the machine has foun tothe intended 
length, it is thrown out of the gear by a: 
clutch, or othérwife, and thereby the cy- 
linder is difconneécted from the band which 
puts the machine in motion, under the ac- 
tion of the poweremployed. 
By Mr. Huddart’s method the longeft 
hemp, flax, &e. may be fpun without having 
its fibres reduced in length. It is.alfo wet 
adapted to fpinning, froin fliveis or rov- 
ings previoufly prepared by fuca machirery 
as has been ufed, or may be ufed for hemp: + 
or flax. Thete flivers or rovings are to be 
delivered by roliers, in any required ratio 
or proportion’to the length of yarns, and 
comprefled by fome flexible fubfiance, fuch 
as cloth, lift or leather, and which com- 
preffion may be given by a weiglit attached 
to the flexible fubitance.
