page_text: We, THE FLAX COMBING SYNDICATE LIMITED, of Throgmorton House,
Copthall Avenue, in the City of London, and TAYLOR BURROWs, of Hope Villa,
Clarence Street, Staines, Engineer, do hereby declare the nature of this invention
to be as follows::
This invention like Letters Patent No. 28680 of 1897 relates to the feed or
feeding arrangements of Noble combing machines or the like more especially
to convert or adapt same for the purpose of combing vegetable fibre such as
flax said Patent No. 28680 of 1897 describing the bobbins or reels mounted in
V-shaped bearings and means to lift said bearings in order to produce a slackness
in the sliver between the reel and feed boxes just before the feed takes place and
thereafter. the reel is lowered again and thereby the amount of the sliver used at
cach feeding operation is thus unwound from the reel.
Instead of providing the bobbins or reels with arbors or trunnions or an axle
or the like on which said reels revolve as described in the said Patent No. 28680
of 1897 such arbors or axial bearings are dispensed with and according to the
present invention the reels are not journalled or supported axially either in
V-shaped or any other axial bearings but instead thereof and according to the
present invention each bobbin or reel is simply rested on rollers one or more of
which are adapted to be raised and lowered or laid in a separate dish trough
or bearing (advantageously a V-shaped bearing or support) whereby each reel is
supported peripherally instead of axially with means to raise and lower
successively the said support or a part of said support for each said reel for
instance if a dish-like support is used either to lift the reel direct or to lift one or
more of the rollers on which the reel rests such dish is carried on a pivoted lever
or otherwise suitably mounted in suchwise that it is adapted to be alternately
lifted and lowered or otherwise moved towards and away from the feed boxes or so
reciprocated that a slackness is produced in the sliver just before each feeding
operation and after the latter has taken place the return motion of the reel will
then unwind therefrom the amount of sliver used in each such feeding operation.
The surface of the dish or support against which the periphery of the bobbin or
reel rests (either the periphery of the bobbin flanges or of the sliver itself) or
the rollers supporting same may advantageously be of such a character that same
will have a braking or retarding action on the revolution of the bobbin and
prevent excess of unwinding.

We, THE FLAX COMBING SYNDICATE LIMITED, of Throgmorton House,
Copthall Avenue, in the City of London, and TAYLOR BURROWs, of Hope Villa,
Clarence Street, Staines, 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, like Letters Patent No. 28680 of 1897, relates to the feed or
feeding arrangements of Noble combing machines or the like more especially
to convert or adapt same for the purpose of combing vegetable fibre such as flax-
said Patent No. 28680 of 1897 describing the bobbins or reels mounted in
V-shaped bearings and means to lift said bearings in order to produce a slackness
in the sliver between the reel and feed boxes just before the feed takes place and
thereafter the reel is lowered again and thereby the amount of the sliver used at
each feeding operation is thus unwound from the reel.
Instead of providing the bobbins or reels with arbors or trunnions or an axle or
the like on which said reels revolve as described in the said Patent No. 28680
of 1897 such axial bearings are dispensed with and according to the present
invention the recls or "balls" of sliver are not journalled or supported axially
either in V-shaped or any other axial bearings but instead thereof and according
to the present invention each bobbin recl or "ball" (which will hereinafter be
referred to as the reel) is simply supported peripherally and means are provided
to raise and lower the said support or a part of said support for each said reel for
instance said reel may be supported on rollers one or more of which are adapted
to be raised and lowered or each said reel may rest in a separate dish trough or
bearing (advantageously a V-shaped bearing or support) whereby each reel is
supported peripherally instead of axially with means to raise and lower
successively the said support or a part of said support for each said reel for instance
if a dish-like support is used either to lift the reel direct or to lift one or more
of the rollers on which the reel rests such dish may be carried on a pivotted lever
or otherwise suitably mounted in suchwise that it is adapted to be alternately
lifted and lowered or otherwise reciprocated or moved in suchwise that a slackness
is produced in the sliver just before each feeding operation and after the latter
has taken place the return motion of the reel will then unwind therefrom the
amount of sliver used in each such feeding operation.
The surface of the dish or support against which either the periphery of the
reel rests or the periphery of the wound ball of sliver itself rests, or the roller
supporting same, may advantageously be of such a character that same will have
a braking or retarding motion on the revolution of the reel and prevent excess
of unwinding for instance the dish or support may be V-shaped or similarly
shaped so that the reel will rest upon the converging sides of said dish or support.
Referring to the drawings hereunto annexed:-
66
Fig. 1 is a local" view or diagram showing the reel or bobbin resting on two
rollers and in its normal position i.e. not raised.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is similar view to Fig. 1 showing the reel in the "raised" position and
the slivers thrown slack.
Fig. 4 shows the reel supported in a V-shaped dish or support instead of upon
two rollers as in Figs. 1 to 3.
a and b are two supporting rollers on which the periphery of the reel & rests the

page_text: axis or arbors e of these rollers a and b respectively rest in bearings d formed in
the arms e or fixed to the revolving frame f of a circular combing machine of
the Noble or the like character.
To this frame f is hinged at f the dish or device y from the underside of which
depends the arm or lever g-the horizontal part of said dish g extending under
the roller a and touching same or proximate thereto in its normal position as
shown in Fig. 1.
h is a fixed cam-surface or striking plate formed on or fixed to a fixed part of
the frame of the machine just at the point where each "feed" takes place.
Thus as the revolving part of the machine travels round same carries round with
it the aforesaid part f together with the arms e and the pair of rollers ab for each
reel z as also the dish or device g with its arm or lever g¹ extending downwardly
therefrom.
Just at or before the moment when the feed takes place that is just at the
moment when the sliver y will by the usual or any suitable feeding mechanism be
drawn through the eye z on the revolving part of the machine, the arm or lever gl
will ride up the cam-surface h and thereby the device y will be moved upwards
upon its hinge fi and thereby the dish y will raise roller a in its bearings d and
thus raise the reel and consequently cause a slackness in the sliver y between
the reel or "ball" and the feed boxes (see Fig. 3) which thus permits the feed-
ing operation to readily take place and after the feed has taken place the lever gl
rides off the cam-surface h and thus permits the descent of the reel to its normal
position again as shown in Fig. 1 and thereupon the amount of sliver y which
has been absorbed after such feed is now unrolled off said reel and then the
latter comes to rest and no excess of unwinding takes place and consequently the
sliver is maintained in a taut condition between the reel a and the feed boxes
until the next feeding operation whereupon the reel is raised again as herein-
before described and so on.
In Fig. 4 a V-shaped dish g* is shown the periphery of the reel resting upon
the converging sides of said device g*--this dish being raised and lowered bodily
by means of the arm or lever g' extending downwardly from the underside of said
dish and engaging with the cam-surface h so as to raise the reel at or just
before the time when the feed takes place and thereafter allowing said dish g* and
reel therein to descend as and for the purpose hereinbefore described with
reference to Figs. 1 to 3; by thus supporting the reel a between the converging
sides of a dish or support such as the latter causes a retarding action on the
revolution of the reel and so prevents any excess of unwinding taking place and
consequently serves to maintain the sliver in a taut condition.
It will be obvious that the supports, on which the reel rests peripherally as
aforesaid, instead of being raised and lowered may be reciprocated in any other
desired direction or may be otherwise caused to move in any other desired manner
(for instance in a circle or in an ellipse) so as thereby to cause slackness in the
sliver between the feeding boxes and each reel in succession at or just before
the time when each feeding operation takes place.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In Noble combing machines or the like the combination therewith of movable
supports upon which the reels of sliver are adapted to be supported peripherally
(and not axially) and means to move said supports for each reel--or a part of
said support for each reel-in suchwise that a slackness is caused in the sliver
between the feeding boxes and the reel during the feeding operation and thereafter
the reel returned to its normal position.
2. In Noble combing machines or the like the combination therewith of movable
supports upon which the reels of sliver are adapted to be supported peripherally
(and not axially) and means to move said supports for each reel-or a part of

page_text: said support for each reel-in suchwise that a slackness is caused in the sliver
between the feeding boxes and the reel during the feeding operation and thereafter
the reel returned to its normal position substantially in the manner and for the
purposes hereinbefore described with reference to the accompanying drawings.
