Year: 1870

page_text: LETTERS PATENT to Edward Barnard Sampson, of Hope Mills, near
Stroud, in the County of Gloucester, for the Invention of "IMPROVE-
MENTS IN MEANS OR APPARATUS FOR FEEDING MACHINERY EMPLOYED IN
PROVISIONAL SPECIFICATION left by the said Edward Barnard
Sampson at the Office of the Commissioners of Patents, with his
Petition, on the 20th April 1870.
I, EDWARD BARNARD SAMPSON, of Hope Mills, near Stroud, in the
County of Gloucester, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MEANS OR APPARATUS FOR FEEDING MACHINERY EMPLOYED
IN CARDING OR PREPARING WOOL AND OTHER FIBROUS SUBSTANCES," to be as
follows:-
My improvements relate to an arrangement or combination of means
or apparatus for feeding machinery employed in carding or preparing
wool or other fibrous substances, by which wool or other fibre may be
automatically fed to such machinery, and the chamber or space occupied
by the wool or other fibrous substance placed in position to be fed
decreases in capacity in proportion as the wool or other fibre is drawn

page_text: away from the said chamber or space and fed to the carding or preparing
machine, by which means an equal weight or pressure of fibre against
the delivery end of the apparatus is obtained.
In carrying out my Invention I employ a rectangular framing, provided
with bearings to support and carry a pair of rollers which support a
travelling apron, which is arranged to support and carry a travelling
partition, so formed that when the apparatus is in operation, the travelling
partition forms one end and two sides of a chamber or space, in which
is placed the proper quantity of fibre to be fed, whilst the other end of
such chamber or space is formed by an endless travelling apron which
is carried by rollers, and is provided with spikes, teeth, or cards, set
across its surface in position to take up continuously a portion of the
fibre from the chamber or space, and deliver it to the stripper of the
scribbling or carding engine to be fed. At each side of the rectangular
framing of the apparatus I arrange a narrow travelling band, to assist
in supporting and carrying the travelling partition. These bands,
as also the travelling apron supporting the partition, are provided,
with guides or clips, arranged at equal distances apart, in order that
when the partition has been carried forward, so that the whole of the
fibre has been fed to the carding or other machine the partition may be
placed in the next series of guides or clips, and a fresh chamber thereby
formed of equal capacity to that just empty. The attendant will then
place the proper quantity of fibre in such chamber, and the motion of
the various parts being so arranged that the travelling apron and the
supporting belts shall advance in proportion as the delivery apron feeds
the fibre to the machine (and consequently diminishes the capacity of
the chamber), an equal weight and pressure of fibre against the delivery
apron during the whole of the process is obtained.
In order to prevent large quantities or "lumps" of wool being taken
up by the travelling apron, a regulator is caused to work to and fro
near to the delivery end of the apron, by which means any such large
quantities or "lumps" will be removed. In place of employing an
endless travelling apron carried by rollers, and provided with spikes,
teeth, or cards, set across its surface to take up the fibre from the chamber,
I in some cases employ a cylinder having spikes, teeth, or, cards upon
its surface, and so placed as to form one end of the chamber or space in
which the wool is placed.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Barnard Sampson in the Great Seal Patent
Office on the 19th October 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
BARNARD SAMPSON, of Hope Mills, near Stroud, in the County of
Gloucester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of April, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Edward Barnard Sampson, Her special licence
that I, the said Edward Barnard Sampson, my executors, administrators,
and assigns, or such others as I, the said Edward Barnard Sampson,
my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN MEANS OR APPARATUS FOR FEEDING MACHINERY EMPLOYED IN
CARDING OR PREPARING WOOL, AND OTHER FIBROUS SUBSTANCES," upon the
condition (amongst others) that I, the said Edward Barnard Sampson,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Barnard Sampson, do
hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :-
My improvements relate to an arrangement or combination of means
or apparatus for feeding machinery employed in carding or preparing
wool and other fibrous substances, by which wool or other fibre may be
automatically fed to such machinery. For this purpose the wool or
fibre to be fed to a carding or preparing machine is placed into a chamber
the sides of which are parallel to one another. At one end of the

page_text: chamber is an endless travelling surface of card teeth, or spikes to take
up continuously a portion of the fibre from the chamber and deliver it
to the licker-in roller of the carding or preparing machine; or the fibre
might be taken from the endless card surface by a doffer and carried
forward by a suitable feed motion to the carding or preparing machine.
The opposite end of the chamber is formed by a travelling partition,
which as the fibre is drawn away from the chamber is caused to move
forward towards the travelling surface of card teeth or spikes at such a
speed as to maintain a continuous and even pressure of fibre against the
delivery end of the apparatus. When the travelling partition has been
carried forward to within a short distance of the delivery end of the
apparatus another partition is placed in rear of it, and a weighed quantity
of fibre is thrown into the space between the two partitions and spread
evenly between them. The foremost partition is then taken away and
the fibre in the chamber is carried forward continuously by the last
inserted partition.
At Figure 1 of the Drawings hereunto annexed is shewn a longitudinal.
section of an apparatus constructed in the manner I prefer for carrying
out my Invention. In this Figure a, a, is one of the two sides of the
chamber, which sides are fixed vertically and parallel with one another;
b, b, are rollers passing across from one side of the chamber to the other
and carried in suitable bearings in the sides; c is an endless apron formed
by preference with transverse slats and supported by the two rollers b, b;.
this apron forms the bottom of the chamber into which the wool or fibre
is placed. d, d, are endless chains placed on the outer side of each of
the side plates a; each of these endless chains is supported on chain.
wheels e, c, capable of turning on suitable studs or axes carried by the
side plates a. f is one of the travelling partitions which is to form the
rear end of the chamber; this partition is shewn separately at Figure 2.
fare studs projecting from the bottom of the partition; these studs are
to enter into holes formed to receive them in one or other of the slats of
the endless apron c.
Such holes are formed through four or other
number of the slats at distances apart around the apron, and each of
such slate is formed of metal. fare studs projecting sidewise from the
top of the partition; these studs are suitably attached to the endless
chain d in such manner that the partition can readily be lifted up away
from the endless chains and apron. g is the endless band provided
with card teeth or spikes; this band is supported on rollers h, h, at the
delivery end of the chamber. is the licker-in roller of a scribbling,

page_text: carding, or preparing engine to which the wool or fibre is delivered by
the endless band g.
Motion is transmitted to the apparatus in the following manner:
:-The
axis of the upper roller is driven continuously in any suitable manner;
on this axis is a bevil wheel which gears with a bevil wheel on an inclined
shaft ; on the lower end of this shaft is a worm gearing with a worm wheel
on the axis of one of the rollers b, and a slow continuous motion is thus
given to the endless apron c. On the axis of the roller b, which is thus
driven, is a chain wheel from which motion is transmitted by an endless
chain to the axis of one of the pulleys e, and thus the endless bands d, d,
are caused to travel at the same speed as the apron c. m is a coarse
comb which is carried by spring arms », which press downwards on to
eccentrics o, o, on the ends of an axis which is driven by an endless band
from the axis of the licker-in roller of the carding, scribbling, or
preparing machine, and by this means a vertical to-and-fro motion is
given to the comb. The comb works to and fro near the endless band g
and serves as a regulator to strip off from it any lumps or large masses
it might otherwise carry up with it.
The mode of working the apparatus is clearly described above, so that
it is unnecessary to give any further description of it.
The Diagram view Figure 3 shows how a cylinder furnished with
card tooth or spikes may be employed in place of an endless band.
Having thus described the nature of my Invention and the manner
of performing the same, I would have it understood that what I claim
is, the combination or arrangement of apparatus substantially as herein
described for feeding machinery for carding or preparing wool and other
fibrous substance.
In witness whereof, I, the said Edward Barnard Sampson, have
hereunto set my hand 'and seal, this Fourteenth day of October,
in the year of our Lord One thousand eight hundred and seventy.)
