Carding machines.
We, JOHN EDWARD SHAW, director of the company of John Shaw and Sons
Limited, of Brookroyd Mills, Stainland, near Halifax, Yorkshire, and JOSEPH
DAVIDSON, of the same place, Director do hereby declare the nature of this
invention to be as follows:-
This invention relates to machines employed for feeding wool and other fibre to
carding and scribbling machines, and more especially to that class of machine where
a spiked endless travelling sheet works vertically for the purpose of carrying fibre
from a low elevation to a higher elevation.
Our improvements in such machines consist in the employment of a series of spiked
bars placed horizontally, which bars have a reciprocatory motion backward and forward
given to them, singly or in pairs, by a suitable arrangement of wheels and connecting
rods, so that the wool or fibre resting upon such spiked bars will be carried forward
and brought into contact with the spiked vertical lattice sheet, consequently the
fibre is fed to such vertical lattice sheet continuously, and as the horizontal spiked
bars can be made of any convenient size, it follows that a very large quantity of wool
can be fed to the machine, and left there without the attention of a workman.
By this means, the hopper usually employed to receive the fibre, and supply same
to the vertical lattice sheet, may be considerably enlarged.

Improvements in Machines for Feeding Wool and other Fibre to
Carding Machines.
We, JOHN EDWARD SHAW, director of the Company of John Shaw and Sons,
Limited, of Brookroyd Mills, Stainland, near Halifax, Yorkshire, and JOSEPH
DAVIDSON, of the same place, Director, 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 machines employed for feeding wool and other fibre to.
carding and scribbling machines, and more especially to that class of machine where
a spiked endless travelling sheet works vertically, for the purpose of carrying fibre
from a low elevation to a higher elevation.
Our improvements in such machines consist in the employment of a series of
spiked bars placed horizontally, which bars have a reciprocatory motion backward
and forward given to them, singly or in pairs, by a suitable arrangement of wheels
and connecting rods, so that the wool or fibre resting upon such spiked bars will be
carried forward and brought into contact with the spiked vertical lattice sheet.
consequently the fibre is fed to such vertical lattice sheet continuously, and as
the horizontal spiked bars can be made of any convenient size, it follows that a very
large quantity of wool can be fed to the machine, and left there without the attention
of a workman.
In order that our invention may be better understood, we herein make reference to
the figures on the annexed sheet of drawings, and to the letters of reference marked
thereon.
Fig. 1 is sectional elevation of a hopper, having our improvements applied thereto,
into which hopper the fibre is placed previous to being fed to the carding machine,
and Fig. 2 is plan view of the said hopper.
A represents the hopper, which may be of any suitable construction, design, and
size, and a is the door through which the fibre is placed. B is the ordinary vertical
spiked lattice sheet placed at that end of the hopper which is nearest the carding
engine, and driven from any suitable moving part of the machine. It is to this
class of feeding machine,-.e., where the fibre is carried from a lower to a higher
elevation by means of a vertical spiked lattice sheet,-that our invention more
especially refers, although it may be used in connection with other descriptions of
feeding machines; and our said invention consists in employing a number of spiked
bars or rods C placed horizontally near to the bottom of the hopper A, such spiked
bars being caused to reciprocate backwards and forwards alternately, either singly or
in pairs. The fibre to be fed to the carding machine is first placed into the hopper A
and rests upon the horizontal spiked bars C, which as they move alternately in the
direction of the arrow b, dislodge portions of the fibre from the bulk and carry
it forward a distance equal to the advancing movement of the said bars, the return

page_text: or backward movement thereof withdrawing the spikes from the portions of fibre so
carried forward, by which means an equal layer of fibre is carried forward to the
vertical lattice sheet B, into the weighing scale of the feeding machine, or onto an
endless travelling apron.
If preferred, the fibre may be deposited by the endless travelling sheet B into a
second hopper, which would thus be always uniformly supplied with fibre from the
first hopper and materially assist in obtaining a correct and equal feed of material to
the carding machine.
In order to give necessary reciprocatory motion to the spiked bars we secure a
short shaft D to one side of the machine, upon which is mounted a pulley E, or fast
and loose pulleys may be employed, driven by strap from any suitable moving part of
machine. On the same shaft D is a pinion F which gears with the spur wheel G
mounted on the shaft c which extends from side to side of the hopper, and carries at
the opposite end thereof (as shewn in Figs. 2 and 3) a disc or fan plate H, to which
is connected eccentrically one end of a rod 1, the opposite end thereof being con-
nected to the lever arm J secured to the shaft d, which also extends to the opposite
side of the hopper. L is a lever mounted centrally on the shaft d, to one end of
which lever L we connect a rod e, the opposite end of which is attached to the cross-
bar f, to which each alternate spiked bar C is bolted, the remaining or alternate bars
being bolted to another crossbar g connected by the rod / to the opposite end of
the lever L.
A second lever L', on the opposite side of the machine, is in like manner mounted
on the said shaft d at the opposite side of the hopper and connected by the rods e¹
and h¹ to the plates and 9 respectively.
When motion is communicated by pinion F and spur wheel G to the shaft c, the
disc H is made to rotate, whereby the lever arm J through the medium of the rod I
is caused to reciprocate, consequently the shaft d and the levers L and L¹ thereon are
also caused to reciprocate, whereby the rods e, h, and e¹, h¹, together with the spiked
bars C are all moved backwards and forwards in the bottom of the hopper.
The means above described for reciprocating the spiked bars C may be varied as
found necessary, as other well-known motions for giving reciprocatory motion may
be substituted therefor.
A projecting piece k having spikes thereon may be secured to inside of the hopper
for the purpose of preventing the fibre from getting between the ends of the bars and
the hopper, which would interfere with the working of the said bars.
By the means herein set forth the fibre can be uniformly and evenly fed to the
carding machine; whilst the hopper may be of considerable size and a larger quantity
of fibre placed therein than formerly.
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 :-
In mechanism for feeding fibre to carding or scribbling machines, the use of
reciprocatory horizontal spiked bars in combination with a spiked vertical endless
travelling apron or sheet, substantially as herein described.
