Improvements. in Means for Applying Friction to the Rotary
Nippers of Machines for Combing Wool and other Fibres.
We, JOSEPH BINNS of 10 Rose Street Keighley in the County of York, Engineer,
and JOHN SKINNER of Morton Banks near Keighley aforesaid, Overlooker, do hereby
declare the nature of this invention to be as follows, that is to say:—
It relates to improvements in means for applying friction to the rotary
nippers of machines for combing wool and other fibres, said machines being
of the class well known as of the Little and Eastwood's principle. And this inven-
tion consists of the application, construction and arrangement of parts so that said
rotary nippers may be more easily operated and that with a greater degree of
stability or precision than heretofore.
The object of this invention is attained by dispensing with the rope usually
employed for retarding the rotary motion of the revolving nippers, the same being
old and well known, and mounting suitably shaped clamps or straps in appropriate
positions, to span the hoop formed on the outer end of the above-named rotary nippers,
in place of the said rope.
These clamps or straps have their inner surfaces appropriately prepared (as by
being covered with leather etc.) so that they are suitable for contact with the hoop
attached to the nippers, and said clamps or straps are hinged one to the other (or
instead of two of such clamps or straps being employed, one may be used by being
mounted) in such a manner that by suitable connecting-rods they (or it) may be
operated by a cam arrangement, driven from any suitable motor shaft of the machine,
to relieve the rotary nippers of unnecessary friction or to apply said friction thereto
as and whenever desired.
-
From this it will be seen that less power is required to operate the rotary nippers,
since, when they are to be rotated, they are relieved of their retarding or friction-
imparting parts, and since these parts are brought into contact therewith just at
the proper time in the rotation of said nippers, their place of rest is arrived at
with greater precision, and the oscillatory or vibratory motion of same consequent
to the usage of a rope as above described, on account of the yielding of said rope, is
entirely avoided.

page_text: Improvements in Means for Applying Friction to the Rotary
Nippers of Machines for Combing Wool and other Fibres.
We, JOSEPH BINNS of 10, Rose Street Keighley in the County of York, Engineer,
and JOHN SKINNER of Morton Banks near Keighley aforesaid, Overlooker, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, that is to say :-
It relates to improvements in means for applying friction to the rotary
nippers of machines for combing woo and other fibres, said machines being of
the class well known as of the "Little and Eastwood's principle. And this inven-
tion consists of the application, construction and arrangement of parts so that said
rotary nippers may be more easily operated and that with a greater degree of stability
or precision than heretofore.
In order that this invention may be more readily understood, we have hereunto
appended sheets of drawings 'illustrative thereof, to which by figures and letters
reference is made in the following description..
Fig. 1 is a sectional side view of such a portion of a combing machine as is
necessary to shew the application of our invention. Fig. 2 is a front view of same,
while figs. 3, 4 and 5 are detail drawings hereinafter referred to. Fig. 6 is a side
view of a modified arrangement of our invention, the framework being omitted for
the sake of clearness.
Similar figures and letters of reference indicate-similar parts throughout the several
views.
We attain the object of our invention by dispensing with the rope usually
employed for retarding the rotary motion of the revolving nippers, the same being
old and well known, and using in place thereof the strap a which is hinged at 6 to a
projecting piece carried by the framework of the machine. This strap a is
formed or made to span the hoop d which is attached to the rotary nippers e, and
to the end of said strap is attached the rod g which is operated by the cams h
and through the medium of the lever and rod k, said cains being mounted
upon the rotary shaft l. From this it will be seen that by the cams h¹ being
arranged to operate.the strap a so that when the rotary nippers e are being rotated,
their hoop d is relieved of the retarding action of said strap a by means of same
being lifted out of contact with it (said hoop d) by the cam .h, said nippers e may more
easily be rotated. Again when the revolving motion of the nippers e.is.desired to be
arrested it may with precision be so arrested by means of the cam h¹ forcibly drawing
the strap a into contact with its hoop d thus the oscillatory or vibratory motion of
said nippers incident to the usage of a rope or other means for continuously imparting
friction thereto as is well known is entirely avoided and the rotary motion of the
nippers e is arrested at exactly the desired time relative with that of the other motor
parts of the machine.

page_text: The strap a has its inner surface a' covered with suitable material (as leather)
for contact with the surface of the hoop d for purposes well known, it has also its
jointings at e and hinged as well as at f¹ in order to allow the necessary movements
of same without its bending or yielding when in operation thus obviating the liability
of causing saine to break.
Instead of the strap a being formed as above described it might be dispensed with
and the clamp m substituted for same as shewn by fig. 6.
The clamp m may be operated by one cam / only, its retracting movement being
dependent upon gravity.
Again in connection with the strap a only one cam h may be employed, in this
case the retracting movement being effected by a spiral or other spring as will be
readily understood, however we preferably make use of the two cams h and h¹ to
effect the operations as hereinbefore described.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, wo declare that what we
claim is:
1. The strap a, the rotary nippers e having a hoop d, the cams and the inter-
vening rods and lever in combination the same being arranged to operate in the
manner and for the purpose substantially as herein specified.
2. The clamp m, the nippers e having a hoop d attached thereto, the cam and the
intervening rods and lever in combination, the same being arranged to operate in the
manner and for the purpose substantially as specified.
3. In a machine having rotary nippers the employment of the means substantially
as herein described for the purpose of intermittently retarding the revolving motion
of same in the manner and for the purpose specified.
