Mechanic. "IMPROVEMENTS IN OR APPLICABLE TO NOBLE'S COMBING MACHINES".
This Invention has reference to apparatus to be applied to the drawing off rollers
employed in Noble's combing machines.
In the practical working of such machines it is occasionally found that a "lap"
or an accumulation of loose fibres forms around one of the said rollers, which in
addition to such fibre becoming waste, is a source of constant danger to the pins in
the circular comb, sometimes bending such pins and at other times stripping them
of the combs, necessitating a stoppage of the machine for repairs, and consequent
loss of time.
The object of our Invention is to provide apparatus for stopping the rotation of
the comb as soon as ever a small "lap" gathers around the said drawing off roller,
and this we accomplish by self-acting mechanism.
For the purpose of carrying out our Invention, we make use of the usual rubber
working in contact with the drawing off rollers for wipeing the moisture therefrom
given off by the wool. We now hinge the said rubber and employ a spring for
forcing it against one of the rollers.
In connection with this hinged rubber are a series of levers and rods, which
are also in connection with the usual stop rod, so that when a "lap" is forming
around the drawing off roller, the thickness thereof above the surface of the roller
will raise the hinged rubber in such a manner that the levers and rods connected
thereto will release the stop rod, and stop the machine.
The wipeing rubber now serves two purposes, one being to wipe the moisture off
the rollers, and secondly to raise on its hinged joint, and stop the machine on the
formation of a lap.

MACHINES."
M
This Invention has reference to apparatus to be applied to the drawing-off rollers
employed in Noble's.combing machines..
In the practical working of such machines it is occasionally found that a "lap"
or an accumulation, of loose fibres forms around one of the said rollers which in
addition to such fibre becoming waste is a source of constant danger to the pins in
the circular comb, sometimes bending such pins, and at other times stripping them
off the combs, necessitating a stoppage of the machine for repairs and consequent
loss of time.
The object of our Invention is to provide apparatus for stopping the rotation of
the comb as soon as-ever a small "lap" gathers around the said drawing-off roller,
and this we accomplish by self-acting mechanism.
For the purpose of carrying out our Invention, we make use of the usual rubber
working in contact with the drawing-off rollers for wipeing the moisture therefrom
which is given off by the wool. We now attach the said rubber to a hinged bar
and employ a spring for forcing the rubber against one of the rollers.
Such being the nature and object of our Invention, we will now proceed to
describe same more fully; reference being made to the accompanying Sheets of
Drawings wherein Fig. 1 is sectional elevation of so much of a Noble's combing
machine as is necessary to illustrate our improvements, and Fig 2 is plan view of
same. A are the small circular combs, supported by pillars B in the ordinary
manner. C and D are the drawing-off rollers, one pair working in connection
with the large circular comb, and the other pair working in connection with the
smaller combs A as will be well understood by those conversant with this class of
machinery. E is the ordinary pad or rubber hitherto employed for the purpose of
wiping moisture from the drawing-off rollers, but which pad or rubber we now
employ for additional purposes and therefore attach it to a vertical rod F hinged
at a such pad being forced against the drawing-off rollers by a flat spring b. The
foot of the vertical rod F passes through a hole, or is otherwise connected to a bell
crank lever G attached to the horizontal bar H, which rod by means of a finger or
projection c can be made to operate the hell crank lever I (see detail Fig 3) in such
manner as to pull down the vertical rod J removing the weighted catch lever K
from contact with the sneck d on the stop rod L which when relieved is
immediately slided in its bearings by spring e whereby the driving strap is
removed from the fast to the loose pulley and the machine stopped.
It will therefore be seen that so long as the drawing-off rollers are clean and free
from fibre, that the mechanism we have described will remain inoperative; but
when a "lap" or a quantity of loose fibre accumulates upon the drawing-off roller
that the pad or rubber E will be pushed outward, thereby causing the vertical
rod F to oscillate upon the binge a consequently the bell crank lever G would
operate the horizontal rod H in the direction of the arrow pulling down the rod J
immediately stopping the machine.
On a close examination of the drawing it will be observed that the bell crank
lever G cannot be applied to the vertical rod F in connection with the small

page_text: circular combs, we therefore employ instead thereof a straight lever M hinged at f
(see plan Fig 2) which when operated in the direction of the arrow-g will slide the
horizontal rod H in the same manner as the bell crank lever G.
By the employment of mechanism such as is herein shown and described, the
machine is stopped immediately upon the formation of "laps" on the drawing-off
rollers whilst the waste of fibre and danger of broken pins are avoided.
The pad or wipeing rubber now serves two purposes, one being to wipe the
moisture off the drawing-off rollers, and secondly to raise on its hinged joint and
stop the machine on the formation of a "lap."
Having now shown and described our Invention; and the manner in which the
same is to be performed and carried into practice, we would have it understood
that we do not confine ourselves to the precise details herein shewn and described,
as some of them can be varied without departing from the main features thereof
what therefore we claim as our Invention is,
Firstly. The employment of the hinged pad or rubber E, for stopping the
machine on the formation of a "lap' on the drawing-off rollers in manner
substantially as herein shewn and described
Secondly. The employment of a pad or rubber which serves the double purpose
of wipeing moisture off the rollers, and stopping the machine.
Thirdly. The employment of the weighted catch lever K when operated by the
formation of a "lap" upon the drawing-off rollers for the purpose of releasing the
stop rod, substantially as herein shown and described
In witness whereof we the said Howard Priestman Francis Kemp Adcock,
John Brown, and James Copley have hereunto set our hands and seals this Sixth
day of February in the Year of our Lord, one thousand eight hundred, and eighty
four.
