"IMPROVEMENTS IN
Hitherto stationary knives have been employed, these being known as the
regulating feed knives."
The old stationary knife does not allow the wool to pass free and straight to
the circle on account of the drag that takes place when the wool passes under
such knives.
Now, I employ a circular rotating knife which assists the wool forward, preserving
it perfectly straight in its course to the circle, and preparing it thereby to be dabbed
into the combs on the circle more evenly by the brush. This feed knife is actuated
by the movement of the revolving circle comb.

DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation. Fig 2 a side clevation; and Fig. 3 a plan looking at
the top representing my improvements and mode of applying the same to wool
combing machines.
a is the circular rotating knife; b is the circle comb; c the wool passing through
the comb. The circular knife a is fitted on to a stud d so as to be capable of
revolving freely; the stud d is attached to the carrier e and capable of adjustment
in the slot hole provided therein. For the purpose of adjusting the knife with
great accuracy and retaining it in that position after being adjusted I employ the
eye bolt g through which the stud d passes, and for the adjusting movement or
arrangement I employ the nuts h. The carrier e is mounted on the brackets i
attached to the framework.
It will be readily seen that by the application of the circular rotating knife a, that
the wool is kept perfectly straight in its course to the circle comb b, the knife a
being carefully adjusted and retained in contact with the wool as shown. As the
circular comb 6 rotates a rotary motion is conveyed therefrom and imparted to the
knife a.
Having now described the nature of the said Invention and shewn by Drawings
how the same may be carried into practice, I would have it understood that I do
not limit myself to the precise limits, details or configuration of the parts I have
expressed and shewn, as the same may of course be varied or modified without in
any way departing from the nature or principle of my Invention, but what I
claim and desire to be secured to me by Letters Patent is,-
The arrangement, construction, and application of circular rotating knife a,
substantially as and for purposes herein set forth.
In witness whereof, I, the said James Carroll, have hereunto set my hand
and seal, this Twelfth day of December, in the year of our Lord One
thousand eight hundred and eighty one.
