page_text: I, GEORGE WILKINSON of Wellington Foundry, Leeds, in the county of York,
Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improvement in the mechanism of Combing machines
on the Heilman system, the object being to take the fibres by the drawing-off rollers
in a line drawn straight through the pins of the feed box combs, and also to seize
the fibres in the nip of the drawing-off rollers closer to the detaining comb and
feed box than can be done by the ordinary system, where the fibres are first
Beized between the top drawing-off roller and a cushion on the cylinder carrying
the combs.
The combs for straightening the fibre are attached to the segment of a cylinder
to which rotary motion is imparted as usual.
Immediately below the feed box are situated the nippers which hold the fibre
while under the action of the rotating combs.-These nippers are carried by a
transverse shaft which is rocked in its bearings by means of a cam on the cam
shaft acting upon an arm of the rock shaft to effect the bite of the nippers.―
Underlying these nippers is the detaining comb swinging from any convenient
centre in the usual manner, it being advanced to strike into the pendent fibre
preparatory to the opening of the gripping jaws.
Set above the comb cylinder is a thin steel plate carried by a pair of rocking
arms pivotted on studs set in fixed brackets.-This steel plate receives a recipro-
cating motion from the combined action of a cam on the comb cylinder shaft and a
pressure spring, the spring serving to force down the steel plate beyond the level
of the detaining comb. The use of this plate is to support the combed fibres
against the pins of the detaining comb, and to introduce the ends of the pendent
fibres into the nip of the drawing off rollers as hereinafter described.
The drawing-off rollers are carried in a frame which swings on a transverse
shaft, which frame is worked by a cam carried by a second cam shaft for the
purpose of advancing the drawing-off rollers to the combed fibre, and drawing
them back when a length of fibre has been taken up.
The action of this apparatus is as follows:-The rotary combs having passed in
the usual way through the fibres held firmly between the nipper plates, the drawing
rollers are moved upwards towards the pendent fibres.-At the same time the

page_text: detaining comb advances to its acting position, penetrating the combed fibre pro-
jecting from the nipper plates.-The nippers will now open, and when the drawing
rollers have approached sufficiently near to the detaining comb to seize the combed
ends of the fibre projecting through the nipper plate, a rotary motion is imparted
thereto by intermittent gearing or other suitable mechanical arrangement, or the
rotation of the rollers may be made continuous.-Meanwhile the thin steel plate,
which had been held back by its cam during the passage of the combs through the
ends of the fibres, is pressed forward by its spring, so that its front edge guides the
combed fibres into the bite or nip of the drawing rollera-By this means the fibres
are firmly seized by the rollers in a line practically straight with the feed box, and
the distance from the nip of the rollers to that of the nipper plates is therefore less
than on the ordinary system, where the top drawing roller is pressed against a
cushion on the combing cylinder.-By these means a greater proportion of combed
fibre is retained, and the percentage of yield is thereby increased.

page_text: I GEORGE WILKINSON of Wellington Foundry, Leeds, in the County of York,
Mechanical Engineer 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:-
This invention relates to an improvement in the mechanism of combing machines
constructed on the Heilmann principle, the object being to take the fibres by the
drawing off rollers in a line drawn straight through the pins of the feed box combs,
and also to enable the drawing-off rollers to seize the fibres closer to the detaining
comb than is ordinarily effected in this class of machine, where the fibres are first
seized between the top drawing-off roller and a cushion on the cylinder carrying the
working combs.
In the accompanying drawing,
Figs. 1 and 2 show in transverse section so much of a Heilmann combing
machine, with my improvements applied thereto, as will explain the nature and
operation of the invention, the working parts being represented in their two
extreme positions.
In these Figures, A is the feed box, B B¹ are the nipping plates or nippers; C is
the detaining comb; D indicates the working combs carried by a shaft D*;—
E E are the drawing off rollers, and F is a curved reciprocating steel plate for
guiding the combed fibres into the bite of the drawing-off rollers.
The combs for straightening the fibre are attached to the segment of a cylinder,
to which rotary motion is imparted as usual.
Immediately below the feed box are situated the nippers B B', which hold the
fibre while under the action of the rotating combs.-These nippers are carried by
a horizontal shaft B*, which is rocked in its bearings by means of a cam 6 on the
cam shaft G, acting upon an arm b¹ of the rock shaft, to effect the bite of
the nippers.
The nipper B is keyed fast to the shaft B, and the arms carrying the nipper B¹
are loose upon the same shaft.-Attached to the nipper B¹ is the feed box A, which
moves therewith when the fibre is presented to the action of the comb D.-As the
nipper B¹ is loose upon the shaft B, it is free to yield to the advancing movement
of the nipper B, and, by its weight, it ensures a proper grip of the fibre drawn
down between the nippers. On the retirement of the nipper B, it follows that
movement, until arrested by a fixed stop, which determines the position the combed
fibre shall take, to bring it into line with the nip of the drawing-off rollers.
The feed box is fitted, as usual, with comb pins for resisting, at the proper time,
the pull on the fibres, the pins subsequently withdrawing, to allow of the further
delivery of the fibres into the machine. Underlying the nippers is the detaining
comb C, swinging from any convenient centre. in the usual manner, it being
advanced to strike into the pendent fibre, preparatory to the opening of the
nippers.
The thin steel plate F, which is set above the comb cylinder, is carried by a
pair of rocking arms f, pivotted on studs set in fixed brackets. This steel plate

page_text: .
receives a reciprocating motion from the combined action of a cam f¹ on the comb
cylinder shaft D*, acting upon a bowl carried upon one of the arms f, and a pressure
spring f, the spring serving to force down the steel plate beyond the level of the
detaining comb C.-This plate has a double duty; it serves not only to introduce
the ends of the pendent fibres into the nip of the drawing-off rollers, but also to
support the combed fibres against the thrust of the pins of the detaining comb,
when this comb is brought into action. The drawing-off rollers E are carried in a
frame E¹ mounted loosely on a shaft E.-A rising and falling motion is imparted
to this frame by a cam e carried by a second cam shaft E**, for the purpose of
advancing the drawing-off rollers to the combed fibre, and drawing them back
when a length of fibre has been taken up.
The action of the above described apparatus is as follows:-
The fibres being presented to the rotary comb by the nippers, as indicated at
Fig. 2, the comb D will, by the rotary motion imparted to it, pass in the usual way
through the fibres, and straighten out the same, after which the nippers will return
to the position shewn at Fig. 1.-Meanwhile, the detaining comb C will advance,
and strike into the pendent fibres, preparatory to their being released from the grip
of the nippers. At the same time that the detaining comb advances, the drawing-
off rollers will move upwards towards the pendent fibres. The nippers, so soon as
the detaining comb has advanced to its acting position and penetrated the combed
fibres (projecting from the nippers), will open, and when the drawing-off rollers
have approached sufficiently near to the detaining comb to seize the combed ends
of the fibre, a rotary motion will be imparted thereto by means of intermittent
gearing or other suitable mechanical arrangement provided for the purpose, or the
rotation of the rollers may be made continuous. As the drawing-off rollers rise to
seize the combed fibres, the thin steel plate F, which had been held back by its cam
during the passage of the combs through the ends of the fibres, is pressed forward
by its spring, so that its front edge guides the combed fibres into the bite or nip of
the drawing-off rollers. By this means, the fibres are firmly seized by the rollers,
practically in line with the feed box, and the distance from the bite of the rollers
to that of the nippers is consequently less than on the ordinary system, where the
top drawing-off roller is pressed against a cushion on the comb cylinder.-By these
means, a greater proportion of combed fibre is retained, and the percentage of yield
thereby increased.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1st The arrangement of a Heilmann combing machine as described, whereby the
fibres from the nipper plates enter direct into the nip of the drawing-off rollers,
and are by them drawn in a straight line through the pins of the feed box, the
distance between the detaining comb and the bite of the drawing-off rollers being
consequently shortened, shorter fibres being retained, and a greater yield of combed
sliver secured.
2nd The employment of a reciprocating plate for introducing the ends of the
combed fibres into the nip of the drawing-off rollers, and acting as a support for
the fibres, to ensure their being penetrated by the pins of the detaining comb.
