IMPROVEMENTS IN MACHINES FOR COMBING FIBRES
Year: 1881

page_text: LETTERS PATENT to George Little, of Oldham, in the County of Lancaster,
Mechanical Engineer, for an Invention of "IMPROVEMENTS IN MACHINES
FOR COMBING FIBRES."
PROVISIONAL SPECIFICATION left by the said George Little at the Office
of the Commissioners of Patents on the 25th July 1881.
GEORGE LITTLE, of Oldham, in the County of Lancaster, Mechanical Engineer.
"IMPROVEMENTS IN MACHINES FOR COMBING FIBRES."
This Invention relates to the class of machine for purpose aforesaid in which a
revolving cylindrical comb having rows or lines of pins of varying pitch or fineness
is employed for combing or cleansing the end or portion of the tuft of fibre,
afterwards seized and held by the nipping jaws or other tuft holding device; this
leading end of the tuft contains nearly the whole noil or other impurity combed
or cleansed from the preceding tuft, and consequently is not readily pierced by the
pins or teeth of; the cylindrical comb referred to; some of the leading pins or teeth
fail to pierce; hence in order to ensure the end of the fibre being pierced and
cleansed it has been necessary to provide more rows of pins or teeth than neces-
sitated by the actual work to be done.
According to this my said Invention I employ in combination with such
cylindrical comb a brush actuated by crank (and connection), slide, or other such
like appliance for giving an intermittent pressure or dabbing action by the brush
on the fibre and comb as to ensure the front line of teeth or pins engaging with
the pile, and I reduce the number of rows or lines of pins or teeth because efficient
action of all pins or teeth employed is ensured, so reducing cost of cylindrical comb
and permitting increased speed of machine with consequent increased production
of combed fibres.

"IMPROVEMENTS IN MACHINES FOR COMBING FIBRES."
This Invention relates to the class of machine for purpose aforesaid in which a
revolving cylindrical comb having rows or lines of pins of varying pitch or fineness
is employed for combing or cleansing the end or portion of the tuft of fibre
previously siezed and held by the nipping jaws or other tuft holding devise; this
leading end of the tuft contains nearly the whole noil or other impurity combed or
cleansed from the preceeding tuft and consequently is not readily pierced by the
pins or teeth of the cylindrical comb referred to.; some of the leading pins or teeth
fail to pierce; hence in order to ensure the end of the fibre being pierced and
cleansed it has been necessary to provide more rows of pins or teeth than
necessitated by the actual work to be done.
According to this my said Invention I employ in combination with such
cylindrical comb a brush operated by cam or crank (and connections), slide, or other
such like appliance for giving an intermittant pressure or dabbing action by the
brush on the fibre and comb as to ensure the front line of teeth or pins engaging
with the fibre, and I reduce the number of rows or line of pins or teeth because
efficient action of all pins or teeth employed is ensured, so reducing cost of
cylindrical comb and permitting increased speed of machine with consequent
increased production of combed libres.
Such being the nature and object of this my Invention I will now proceed to
describe the same in detail, and in order that the Invention may be fully
understood I have hereunto annexed Sheets of Drawings illustrating the same.
Fig. is a side elevation shewing part of combing-machine-having-my
improvements applied thereto; Fig. 2 is a plan view, in which Figures A, A, are
the lap rollers; B, the lap plate; C, C, feed rollers; D, nipper bar and lever;
D is the cushion plate; D2, the swing nipper frame; E, circular comb with steel
segment for detaching the tufts of fibre; F is the top detaching roller; F, the
bottom detaching roller; F2, the brass roller; G, the top comb; at H, H', is the
dabbing brush and its lever; I is the tappet lever; J is the cam lever; K is the
cam ; L is a bracket for carrying tappet and cam lever shaft.
Another mounting for the brush is shewn at Fig. 3, which is a side elevation;
H, H, is the dabbing brush and lever, the cam K operating the runner or
antifriction bowl M, the arm J of the dabbing lever H so imparting the requisite
motion to the dabbing brush.
Fig. 4 shews another arrangement, by which the dabbing brush H is operated
by cam K, cam lever J, connecting rod N, lever P working in fulcrum centre R
jointed at S to brush lever H working on centres T, U.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be or may be performed or
carried into practical effect, I would have it understood that what I claim as my
Invention is,
Firstly. The combination of parts constituting the improvements described and
illustrated by Figs. 1 and 2 of the annexed Drawings.

page_text: Secondly. The combination of parts constituting the improvements described
and illustrated by Fig. 3 of the Drawings.
Thirdly. The combination of parts constituting the improvements described
and illustrated by Fig. 4 of the Drawings annexed or any mere modification
5 thereof.
In witness whereof, I, the said George Little, have hereunto set my hand
and seal, this Twenty first day of January, in the year of our Lord One
thousand eight hundred and eighty two.
GEORGE LITTLE. (L.S.)
