Et IMPROVE-
PROVISIONAL SPECIFICATION left by the said John Charles Walker and
Jonathan Edward Stephenson at the Office of the Commissioners of Patents
on the 21st June 1881.
JOHN CHARLES WALKER and JONATHAN EDWARD STEPHENSON, both of Shipley,
in the County of York. "IMPROVEMENTS IN COMBING MACHINES."
Our improvements have reference to that part of combing machines known as
the feeding or filling head, and the advantages of such improvements are that the
material is more evenly fed to the combing apparatus than heretofore.
First. Wo dispense with the ordinary feed rollers, which are mounted within
the eccentric feeding head, and apply a square motion feeding apparatus, which
consists of any required number of gills fitted so as to slide freely within tho
feeding head; these are moved forward by cams or eccentrics whilst the foeding
head is in motion, carrying the wool with them. Each gill after moving the
required distance is allowed to drop away free from the material, and is moved
forward again to the other end and raised into its former position to continuo the
feeding operation.
Second. Instead of employing cams or eccentrics for giving motion to the gills
we apply screws in a similar manner to that on an ordinary roving frame, whereby
the gills are moved forward for feeding purposes, and afterwards relieved from the
material and conducted into position again for continuing the feeding operation.
Third. We employ as another modification what is known as "Rawson's filling
head," in combination with the herein before mentioned filling head, whereby the
feeding operation of such arrangement is more quickly effected.
Fourth. We make the eccentric which moves the filling head adjustable on its
shaft, so that the stroke of such feeding head may be thereby regulated or
changed.

Our improvements have reference to that part of combing machines known as

First. We dispense with the ordinary feed rollers, which are mounted within
the eccentric feeding hend, and apply a square motion feeding apparatus, which
consists of any required number of gills fitted so as to slide freely within tho

we apply screws in a similar manner to that on an ordinary roving frame, whereby.
the gills are moved forward for feeding purposes, and afterwards relieved from the

Third. We employ as another modification what is known as "Rawson's" filling
head in combination with the herein before mentioned filling head, whereby the
feeding operation of such arrangement is more quickly effected.
Fourth. We make the eccentric which moves the filling head adjustable on its
shaft, so that the stroke of such feeding head may be thereby regulated or
changed.
And in order that our Invention may be more completely understood, reference
is given to the accompanying Drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation, and Fig. 2 a front elevation shewing one arrangement
of our Invention.
In this arrangement we dispense with the ordinary feed rollers (such feed rollers
being usually mounted within the eccentric feeding head a), and apply a square
motion feeding arrangement, which consists of any required number of gills or
fallers b fitted so as to slide freely within the feeding head a.
Theso are carried
forward by the internal framework c being moved in a lateral direction by the
cam or eccentric & through the medium of the bowle on the stud f whilst the
eccentric feeding head is in motion. Each faller bon arriving at position g is
carried down by external framework c' into lower lino of fallers i; then the
framework c is moved in a lateral direction by the cam or eccentric & through the
medium of the bowl e on the stud f carrying the fallers forward. The required
rotary motion is given to the cam or eccentric & through gearing from shaft m.
As each faller b arrives at n the framework c' has been lowered to receive it in
the recess o, and after receiving it again is raised into position shewn in Drawings,
carrying the fallers with it into the top line ready to continue the feeding operation.
The upward and downward movement of the external framework c¹ inay be
effected by cams or eccentrics or their equivalents. n' and n³ are respectively the
upper and lower jaw of compressor, which are for the purpose of laying evenly
the material in the comb circle. The upper jaw n' is moved downwards by the
cams d or their equivalents, and thereby the material is compressed between it
and the lower jaw n². During this compression or nipping operation the jaws by

page_text: friction on the circle travel therewith as far as may be required. On the material
being released by the rising of the upper jaw n¹ the jaws are drawn back to their
original position by a spring or other convenient means. We may in some cases
dispense with the lower jaw n; in this case the nip takes place between the upper
jaw and the top face of the circle.
Fig. 3 is a sectional side elevation, Fig. 4 a front elevation of gills or fallors.
Instead of employing cams or eccentrics for giving motion to the gills or fallers p,
we apply the screws q and r arranged in a similar manner to those on an ordinary
roving frame. In our case the screws 9 and r are mounted in bearings between
the sides of the falling head s. Motion is given to the screws 7 and r from shaft t
through gearing u, and by such motion the gills are moved forward for feeding the
wool, and afterwards relieved therefrom by dropping into and engaging with
the lower scrow r, whereby they are conducted again into position for continuing
the feeding operation.
Fig. 5 is a side elevation, Fig. 6 a transverse section shewing application of what
is known as "Rawson's feed" to eccentric filling or feeding heads.
The eccentric filling or feeding head is shewn at 1, its peculiar movement being
produced in the ordinary manner; to this we apply an arrangement similar to that
which is known as Rawson's feeding or filling head.
The sliver of wool or
other fibrous material rests upon an axis 2 between two projections or ordinary
guides. On the axis 2 there are also mounted two arms 4, the upper ends of
which have slotted openings 6 to receive the projecting pins 7 of sliding bolts 8 of
the comb 9. The sliding bolts 8 slide in the sockets 10 at the upper part of the
bracket 11 of the filling or feeding head 1 which carries the comb 12. The grating
or perforated plate 13 is moved upwards by cams 13' at certain times to free the
comb 12 of the material. The material is then acted upon by the comb 9, to which
is given a to and fro motion through the medium of the arms 14 acted on by a
cain or eccentric 15 on the shaft 16 and springs 17. By this means the wool or
other material is advanced into the combing machine during the time those
materials are clear of the teeth of the comb 12.
In all cases, by preference, we make the eccentric for actuating the feeding or
filling lend adjustable, so that the stroke thereof may be regulated.
Having now described the nature of our said Invention, and particularized the
same by details which answer well in practice, we would have it understood
that we do not confine ourselves to the exact details set forth, but what we do
claim is,
First. The arrangement and application of fallers or gills b and means employed
for actuating the saine on eccentric filling or feeding heads of combing machines,
substantially as shewn at Figs. 1 and 2, and for purposes herein set forth.
Second. The arrangement and application of screws q and for gills or fallors p
on eccentric filling or feeding heads of combing machines, substantially as shewn at
Figs. 3 and 4, and for purposes herein set forth.
Third. The arrangement, application, and combination of a Rawson's filling or
feeding head with an eccentric feeding or filling head, substantially as shewn at
Figs. 5 and 6, and for purposes herein set-forth.
In witness whereof, we, the said John Charles Walker and Jonathan Edward
Stephenson, have hereunto set our hands and seals, this Nineteenth day of
December, in the year of our Lord One thousand eight hundred and
(L.S.)
