PROVISIONAL SPECIFICATION.
Improvements in Automatic Feeding Apparatus for Carding
Engines.
I JOHN HARDMAN of 209 Alliance Place Bell Lane Bury in the County of
Lancaster, Woollen Carder, do hereby declare the nature of this invention to be
as follows:-
This invention relates to that class of apparatus for feeding carding engines
which consists of a scale which when a certain weight of fibre has been fed therein
opens and lets the same fall upon the feed lattice which conveys it to the feed
rollers of the carding engine.
As this action is intermittent and as the opening of the scale has been hitherto
usually parallel with the said feed rollers a thin place has been formed where each
fresh charge of fibres has fallen upon the lattice in spite of the action of the usual
board to push the fresh fibres forward and make the joint good and the beater
which presses and consolidates the said joint.
My invention is designed principally to remedy this defect and for this purpose
I make the scale of such a form and so sloped that when it opens it will deliver
the fibres diagonally across the lattice and evenly thereon.
I also so mount the board and beater that they will act diagonally upon the fibre
on the lattice and so make good the diagonal joint. From this construction it will
be seen that there will be no tendency to the formation of a thin place at the joint
by the feed rollers of the carding-engine.
This construction will also mix the fibres better as there will be less chance for a
thick lump to be passed through the feed rollers since falling diagonally upon the
lattice they will separate as they are drawn in by the said feed rollers.
The construction of the driving mechanism and the mechanism for supplying the
fibres to the scale need not be interfered with.

COMPLETE SPECIFICATION.
Improvements in Automatic Feeding Apparatus for Carding
Engines.
I JOHN HARDMAN of 209 Alliance Place Bell Lane Bury in the County of
Lancaster, Woollen Carder, 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 that class of automatic apparatus for feeding carding
engines (for carding wool and other fibres) which consists principally of a scale
which when a certain weight of fibre has been fed therein opens and lets the same
fall upon the endless feed lattice which conveys it to the feed rollers of the carding
engine.
As this action is intermittent, and as the opening of the scale has been hitherto
usually parallel with the said feed rollers, a thin place has been formed at right
angles across the layer of fibre where each fresh charge thereof has fallen upon the
lattice, in spite of the action of the usual back board to push the fresh fibre
forwards, and the beater which presses and consolidates the said joint.
My invention is designed principally with a view to remedy this defect and to
D

page_text: prevent the occurrence of these thin places which are detrimental to the evenness
of the yarn produced.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the annexed sheet of drawings and the following explanation thereof.
Fig. 1 is a vertical section of so much of the feeding end of a woollen carding
engine as is necessary to illustrate the application of my invention thereto.
Fig. 2 is a plan view of the same with the scale removed.
Fig. 3 is a plan view of my improved scale, and
Figs. 4 and 5 are transverse sections thereof taken at the lines A-B and C-D
respectively, the section of the scale at Fig. 1 being taken through about midway
between these two points.
feed rollers, c the endless
a is the licker-in" of the carding engine. b are the
feeding lattice, d the sliding back-board, e the beater and the scale.
For the purposes of my invention I make the scale of such a form and the
mouth thereof so sloped diagonally (see Fig. 3) that when it opens as shown at
Fig. 1 it will deliver the fibres in a diagonal line across the lattice c and evenly
thereon, notwithstanding that the hinges f¹ of the scale are mounted square across
the lattice and the scale is operated in precisely the same manner as usual.
I also mount the sliding back-board d and the beater e in a diagonal position so
that although actuated in the usual manner they will act on the fibre so as to make
good the diagonal joint thereof, and instead of making the beater e with a flat
surface as usual I prefer to make the same with bevilled corrugations as shown, as
I find that it distributes the fibre more evenly.
"
From this construction it will be seen that as the joint between the successive
" feeds
of the wool or other fibre is not presented all at once in a transverse line
to the feed rollers, but commences at one corner and is distributed and passes
gradually and diagonally across the layer of fibre, there will be no tendency to the
formation of a thin place at the joint by the action of the feed rollers 6 of the
carding engine; as also parts of several "feeds" will pass at the same time between
the said feed rollers b (as seen by the plan, Fig. 2) any inequality in the feeds will
be equalized in a great measure in the carding engine.
This improved construction will also mix the fibres better as there will be less
chance for a thick lump to be passed through the feed rollers, since by falling
diagonally upon the lattice c they will separate as they are drawn in by the said
feed rollers; and as before stated the construction of the driving mechanism (which
is not shewn on the drawing) for supplying the fibres to the scale, and for actuating
the scale, back board, and beater need not be in any way interfered with.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
The improvements in automatic feeding apparatus for carding engines consisting
in constructing the scale with the mouth in a diagonal position, and mounting the
sliding back board and beater also diagonally substantially in the manner and for
the purposes hereinbefore described and set forth and illustrated by the drawings
annexed.
