is to say)-
The description of Figure 1 contains a front view of the spinning machine,
which is as follows:-Z, Z, Z, Z, the frame of the machine supporting all the
works; A, A, the main wheel on which the band B, B, B, B, runs to turn the
spindles P, P; C, a tooth'd wheel fixed behind the band wheel, giving motion
to a fly wheel D, on which work two horizontal wheels E & F, the wheel F
turning a cylinder with a cam and two crankes. G, which move the carriage
H, H, running on four trucks or small wheels; on the carriage are screwed the
drawers I, I. K, K, bobbings holding prepared stuff or rovings of cotton, flax,
wool, silk, &c.; L, L, a frame supporting two directing wheels M, M, turning
each other, through which the rovings pass to be spun; N, the regulating
wheel, moving one tooth at every revolution of the cylinder, directs the wheels
M, M, to bring the rovings, forward to the drawers I, I, the carriage and
drawers moving forwards and backwards by every revolution of the cylinder
spindle staff to a proper size by the drawers I, I, at 0, 0; P, P, the spindles, in
which are fixed the flyers and spoles; Q, Q, a slyding.frame, the under side
notched, by pushing it up and down moves the spoles at pleasure.
The description of Figure II. contains a section of the carriage, trunks,
drawers, cylinder, and cranks..
The description of Figure III. contains a view of the jack and lever
(a, a, a), the spring (b), and catch (c), which work the regulating ratchet
whee! N. One revolution of the cylinder (d) working upon the jack gives.the
wheel a tooth.
☐
The description of Figure IV. contains a view of a preparing machine, which

page_text: is as follows: A, A, a smooth wood frame, on which is placed raw materials,
as flax, hemp, tow, silk, wool, &c., at B, B, B, C, C, two standards fixed in the
frame A, A, supporting a cylinder D; E, a band wheel worked by a main shaft,

which is brought of the cylinder at F by two cushions G, G, and falls into
the box H.
The description of Figure V. contains a view of another preparing machine,
which as follows:-A, A, a frame with two small barrs screwed at right angles
to conduct the rollings brought from the box H, in Figure IV., to two wheels
B, B, supported in a frame C, C, directing the stuff to the drawers D, which
work forwards and backwards by the cranks E; E, and the carriage F, F,
draws the slubb to a proper size at G; I, the regulating wheel, with a jack
spring and catch K, K, K, and L, as in Figure III., gives one tooth by
every revolution of the cylinder M, M.
The description of Figure 6 contains a view of another preparing machine
which is as follows:-A, an upright shaft giving motion to the whole machine;
B, a band wheel, fixed on the top of the upright A; C, C, C, a band passing
over two pulleys fixed on the frame D, D, to the conical pipe E, E, gives it a
circular motion; F, a bobing, hanging on two centres at the end of the cone
holding course rovings, is brought through the pipe E, E, E, by the directing
wheel H, and carried to the drawers I, which forms the slubb to a proper size
at O; the bobbing K, turned by the band wheel L from the main shaft, winds
up the slub from O; M, the carriage, having four trucks, works forwards and
backwards, carrying the drawers I, as in Figure II., and the regulating
wheel H acts as in Figure III.
