(amongst others) that I, the said William Lyall, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Lyall, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings hereunto annexed,
that is to say-
i
My Invention consists in the adaptation to spinning and roving 'machinery
of an oil-tight trough or case, fitted with branches or supports for receiving
the feet or pivots of the spindles, and with a tilting lever or other suitable
contrivance for throwing or depositing the oil upon the gear, and the pivots
contained also' within the trough, for the purpose of keeping the gear as well
as the pivots constantly lubricated. The object of this arrangement is to keep
the oil or other lubricating material free from dust, so that the same material
may be used over and over again, and also to prevent the oil or other such
material from being scattered over the other parts of the machine.
An the Drawings hereunto annexed I have represented several methods of

page_text: carrying my Invention into effect. In each of these methods the oil-tight
trough or case, before mentioned, furnished with branches or supports for
receiving the pivots of the spindles, is employed, but different contrivances are
adopted for throwing or depositing oil upon the gear and the pivots. On
Sheet 1 is shewn one arrangement. Figure 1 is a plan, shewing the trough
or case in section; Figures 2 and 3 are transverse views of opposite sides of
one of the gearing wheels and spindles respectively, also shewing the trough
or case in section; Figure 4 is a longitudinal view of one of the pivots, gear-
ing wheels, and spindles respectively, the spindle in this case being shown with
a flyer fitted upon it. A is the case, which is fitted with a close cover to keep
out the dust, and through this cover the spindles pass; B, B, are the branches
or supports for the pivots C, C; D, D, are the bevilled wheels, which impart
motion to the spindles E, E, by means of the bevelled pinions F, F; G, G,
are the vertical spindle springs, and H is the flyer. In this arrangement the
oil is to be thrown upon the gear and the pivots by means of a plate or
lubricator I (Figures 2 and 3), connected by an axle and crank arm to an
upright rod, to which is communicated a jerking up and down motion by a
lever and spring. Figures 5 and 6 illustrate this contrivance, the former being
an elevation and the latter a plan. a is a portion of the framework of the
machinery; b is the crank arm, by which a long axle carrying the lubricator I
receives motion from an upright rod c, which again receives an up and down
motion alternately from a compound lever d and a spring e. The two extreme
positions of the lubricator are shewn in dotted lines in Figure 5.
On one
portion of the compound lever d is formed a rib or projection f, by means of
which the said lever takes hold of a cap or boss on the rod c and raises it,
thus raising also the crank arm b, and lowering the lubricator I into the oil at
the bottom of the case A. By the time the rod c reaches its highest position,
the rib or projection of slides from beneath the cap or boss on the said rod,
which is then pulled down suddenly by the spring e, and by this means the
lubricator I is jerked upwards, and the oil thrown from within it upon the
wheels, pivots, &c. Figures 7, 8, 9, and 10 are detailed views of the com-
pound lever d. This lever consists of two parts, shown together in Figure 8,
and apart in Figures 9 and 10. One of these parts is fixed to a shaft h, which
receives from some moving portion of the machinery a partial rotary motion
alternately in opposite directions, and the other i is jointed to this part by a
pin j, and has formed on it the rib or projection f, before mentioned. The
part i is capable of turning up in one direction, as indicated in Figure 7, in
order that as the lever d descends, the projection f may be allowed to pass t
cap or boss on the rod c, and fall beneath it, so as to be in a position to raise
"
the

page_text: the rod c again, when the lever d is moved upwards by the shaft h.. 'It should
be stated that the spring e is attached at its lower end to a stud in the frame-
work of the machine, and at its upper end to the cap or boss on the rod c, and
that the rod c works in suitable guides. The whole apparatus may, if thought
desirable, be enclosed in the case A:-
Figures 1, 2, and 3, on' Sheet 2 of the 'Drawings, represent respectively a
Iongitudinal elevation, an end elevation, and a plan of another method in which
the same form and arrangement of lubricator is employed as in the former
case, but in which motion is communicated 'to the lubricator 'in a different
manner. In these Figures, I is the lubricator, as before; "A is a horizontal
lever, which has jointed to it a spring catch B; which 'takes into teeth 'on a
wheel C; D is another spring catch, which prevents the wheel from turning
in one direction; E is a crank arm connected to the axle of the lubricator I,
and F is a spring attached to this crank arm; G is a stud on the wheel 'C;
His a rod through which a rocking motion is imparted to the lever A from
some moving portion of the machinery. As this rocking motion of the lever 'A
takes place, the spring catch B gradually turns the wheel C, and as this wheel
revolves, the stud G is' brought down 'behind the crank arm E, and extends
the spring F until the lubricator I lies in oil at the bottom of the case. The
stud & then passes clear of the crank arm 'E, which is suddenly pulled back
to its former position by the spring F, the lubricator I'is thrown upwards, and
the oil within it is distributed over the wheels, pivots, &c.
'Figures 4, 5, and 6 of the Drawings on Sheet 2, are respectively a longi-
tudinal elevation, an end elevation, and a plan of another method of carrying
my Invention into effect. In each of these Figures the case for containing the
pivots, wheels, &c. is shewn in section. A is the said case, fitted with a close
cover as before; B is the lubricator, which consists of a long plate or dish
supported upon an axis C; D is a curved plate, which has its edges turned up
so as to form gutters c, c; E is a leather strap which passes round the shaft F
and the pulley G; H is a woollen strap which dips into the oil in the bottom
of the case A. The action in this instance is as follows: The shaft F gives
motion to the strap E, which again gives motion to the pulley G, and through
it to the strap H. This strap raises the oil from the bottom of the case and
deposits it in the gutters c, whence it runs into the lubricator B, which is so
balanced upon its axis, that when 'the oil in 'it reaches a certain height it' tilts
suddenly down, throws the oil over the parts to be lubricated, and then falls
back into its former position to receive a new supply of oil.
Figure 7, Sheet 2, is an elevation of an arrangement in which the samé
form of tilting lubricator is employed as in the last case, but in which the oil

page_text: is raised by means of a pump P, which supplies the place of the woollen strap,
&c. used in the former arrangement. The pump P is worked by means of a
rod R, driven by some moving portion of the machinery, and is furnished
with a long spout S, which opens over the lubricator.
Figures 8 and 9, Sheet 2, are a side and an end elevation of another arrange-
ment, in which the same form of tilting lubricator is employed as in the last two
cases, but in which the oil is raised by means of several rollers placed one above
another. The lower roller is placed partly in the oil, and receives motion from
the shaft that drives the spindles; the superior ones receive motion from the
lower one by means of friction flanches or wheels, a space being left between
the adjacent rollers to allow the oil to circulate. A is the tilting lubricator;
B, the spout or gutter for conveying the oil to it; C, C, are the rollers; D is
a wheel for giving motion to the lower one from the spindle shaft; and E, E,
are the spaces between the rollers.
And having now described the nature of my said Invention, and in what
manner the same may be performed, I declare that I claim,--
First, the adaptation to spinning and roving machinery of an oil-tight trough
or case, furnished with a suitable contrivance for throwing or depositing oil or
other lubricating material upon the gear, and the pivots which are contained
within the trough or case, for the purpose of keeping the gear and the pivots
constantly lubricated.
Second, the several arrangements of lubricating apparatus herein-before
described, and represented in Sheets 1 and 2 of the Drawings hereunto
annexed.
In witness whereof, I, the said William Lyall, have hereunto set my
hand and seal, this Thirty-first day of March, One thousand eight
hundred and fifty-six.
WM LYALL. (L.B.)
