PROVISIONAL SPECIFICATION
An Improved Feeding Device for Carding Engines
I CHARIFS AI FRID AI PERLY, of the Firm of Apperly Cuitis & Co,
Woollen Cloth Manufacturet, Dudbud Mills Stroud in the County of
Gloucester, do hereby declare the nature of this invention to be as follows
The present invention elite to improvements upon an invention for which
Letters Pitent were granted to James Apperly and William Clissold, June 2nd
1856, No 2874, for improved machinery for preparing fibrous substances for
spinning
According to that invention, a previously prepared sliver was delivered to the
carding engine for further treatment, by laying it diagonally upon the feeding apron
in parallel serpentine rows In that arrangement, the sliver was pulled through a
pair of idle laying rollers, mounted upon i ti iveller, which tiaversed diagonally
from side to side of the feeding apron, the pulling or drawing of the sliver being
effected by fingers which held the liver at the tuins, while the traveller traversed
to the opposite side of the apron
The holding of the sliver in thit manner had the disadvantage of impairing the
evenness of the feed by reason of the somewhat excessive tension, in proportion of
its strength, to which the sliver was subjected at the commencement of each row
laid on the feeding apron
It is the object of the present invention to ensure a more even feed than
heretofore, and to this end I substitute for the pair of idle rolleis carried by the
traveller, a pair which are positively driven, and which even grip and advance the
sliver, and at the same time lay it on the apron as the traveller passes to and fro
from side to side
The feed 1ollers, as they may now be termed, are arranged verticilly, as formerly,
and are provided with radial blades, which interlock or bite the slivei which passes
between them Each voller caries a spui pinion, which pinions gear together, so
that one roller cannot rotate without the other
The driving is effected preferably by means of a fixed rack, which engages with
one or other of the pinions as the traveller is drawn by suitable mechanism to
and fro
To ensure the driving of the rollers always in the same direction, no matter
which way the traveller 13 going the rollers are carried by a frame which is
pivotally supported on the traveller, so that as the limit of traverse is reached, in
either direction, the frame may be turned on its pivot by contact with a fixed
abutment, and caused to disengage one of the roller pinions, and engage the other,
which continues to drive the rollers, as the traveller takes its opposite traverse
With the aid of this arrangement, a more even laying of the sliver upon the feed
apion can be effected, as the retaining fingers, which were formerly employed for
holding the sliver at the ends of the serpentine rows, and which created a variation
in the tension of the slivers at different points, can now be dispensed with

1 CHARIES ALFRED APPERLY of the Firm of Apperly, Curtis & Co,
Woollen Manufacturers, Dudbridge Mill, Stroud, in the County of Gloucester,
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
-
The present invention relates to improvements upon an invention for which
Letters Patent were granted to James Apperly and William Clissold, June 2nd
1856 No 2874, for "Improved machinery for preparing fibrous substances for
spinning
"
According to that invention, a previously prepared sliver was delivered to the
carding engine for further treatment by laying it diagonally upon the feeding apron
in parallel sei pentine rows In that arrangement, the sliver was pulled through a
pair of idle laying rollers mounted upon a traveller which traveised diagonally
from side to side of the feeding apron, the pulling or drawing of the sliver being
effected by fingers, which held the sliver at the turns waile the traveller traversed
to the opposite side of the apron
The holding of the sliver in that manner had the disadvantage of impairing the
evenness of the feed, by reason of the somewhat excessive tension, in proportion to
its strength, to which the sliver was subjected at the commencement of each row
laid on the feeding apron
It is the object of the present invention to ensure a more even feed than
heretofore, and to this end I substitute for the pair of idle rollers carried by the
traveller, a pair of positively-driven feed rolleis, which grip and advance the sliver,
and at the same time lay it on the apron, as the traveller passes to and fro from
side to side
In the accompanying drawing
Fig 1 shows, in side elevation, a traveller carrying feed rollers embodying my
improvement>
Figs 2 and 3 are plan views of the traveller, with the feed rollers in different
positions
Fig 4 is a plan view on a smiller scale, shewing a portion of the feeding
apron
a a are the positively-driven feed rollers mounted vertically on a pivotted
frame A at the bottom of the traveller A The traveller A depends from and
slides upon the rail B, which extends diagonally across the feeding apron C
(see Fig 4), after the manner described in the Specification of the Patent above
mentioned
The rolleis a a¹ are provided with radial blades aº, which interlock, and bite the
Bliver which passes between them Fast to the rollers a a' are spur pinions d d',
which pinions gear together, so that one roller cannot rotate without the other
The driving is effected preferably by means of a fixed rack D on the framing,
which engages with one or other of the pinions dd, as the traveller is drawn to and
fro across the apron C
To ensure the driving of the rollers always in the same direction, no matter
which way the tiaveller is going, the frame A*, which is pivotally supported on the
traveller, is caused, as the limit of traverse is reached in either direction, to turn on
ats pivot by contact with a fixed abutment E, thereby disengaging one of the roller
pinions, and engaging the other, which continues to drive the rollers as the traveller
takes its opposite traverse
The
Fig 2 shows the traveller just finishing its course from right to left
pinion d is then engaged with the rack D and the projection on the loop F, carried

page_text: by the pivotted frame A*, is in the act of striking the wheel of the abutment E, so
as to rock the fiame A* into the position shown in Fig 3, where the traveller is on
the point of commencing its retuin movement, the pinion d¹ being then in gear
with the fixed rack D
The means for traversing the traveller to and fro may conveniently consist, as in
the before patented arrangement, of an endless belt G carried and driven in any
suitable way, and travelling in a path parallel to that of the traveller A
A projecting finger (not seen) on the edge of the belt engages with a long vertical
slot in the back of the traveller, and pulls the latter backwards and forwards across
the apron while the belt continues to run in the same direction
The loop F, which
rock the frame A*,
I is a guard plate
H is a spring provided with a catch or catches at its lower end for holding the
pinions d or d in gear with the rack D during the travel
carries the projections for f1 for engaging with the stops E to
Is utilized as a lead for the sliver to the feeding rollers a a¹
to keep the fibre out of the teeth of the pinions d, d'
With the aid of this arrangement, a more even laying of the sliver upon the feed
apron can be effected, as the retaining fingers which were formerly employed for
holding the sliver at the ends of the serpentine rows, and which created a variation
in the tension of the slivers at different points, can now be dispensed with
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
-
In feeding apparatus for carding engines, wherein a sliver is laid in serpentine
rows on a feeding apron, the employment of a traveller carrying rollers driven
always in the same direction which rolleis, as the traveller traverses to and fro,
feed forward the sliver, and lay it on the apron, in the manner explained with
reference to the drawing, and for the purpose set forth
