I, HENRY BERNOULLI BARLOW, of Manchester, in the County of.
Lancaster, Patent Agent, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN APPARATUS FOR DELIVERING AND DRAWING LONG.
FIBRED WOOL AFTER. CARDING," being a communication to me from abroad
by John Dobson and James Dobson, both of Philadelphia, in the State.
of Pensylvania, in the United States of America, to be as follows:-

page_text: This Invention consists in preparing the wool on carding engines and
delivering the slivers from any convenient number of carding engines
through one delivery into a can or other receptacle. The carding
engines are placed in a line and the sliver from each is deposited on to
an endless belt travelling in a trough in front of the carding engines.
The united slivers are then taken between a pair of rollers, which
deliver them to a second pair of rollers travelling rather faster than the
first pair to elongate or draw the slivers. The distance between the first
and second pairs of rollers can be adjusted according to the length of
the fibres, which are then carried forward by a third pair of rollers and
deposited into a can or other receptacle. The united slivers are then
taken to the combs or gill boxes. By means of these improvements the
work is better done and with less waste than heretofore. Labour is also
economised.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Bernoulli Barlow in the Great Seal Patent
Office on the 30th June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BERNOULLI BARLOW, of Manchester, in the County of Lancaster, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of January, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Bernoulli Barlow, Her special
license that I, the said Henry Bernoulli Barlow, my executors, adminis-
trators, and assigns, or such others as I, the said Henry Bernoulli Barlow,
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.

page_text: sylvania, in the United States of America, upon the condition (amongst
others) that I, the said Henry Bernoulli Barlow, my executors or
administrators, by an instrument in writing under 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 Henry Bernoulli Barlow, 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, that is to say :-
In preparing long fibre wools for combing on carding machines it has
been the practice to wind the sliver from each card separately in the
form of a ball, requiring an attendant to tend or look after three balling
heads (and in some cases only two), and with the closest attention and
care the balling machines make considerable waste both at the cards and
in unwinding the balls at the combs or gill boxes.
The object of this Invention is to dispense with the balling
heads, and it consists in the combination and arrangement of simple
yet very effective machinery for taking the sliver from the card.
doffers and delivering it on an endless apron or belt, by which it is
carried (with others) to suitable rollers for drawing long fibre wool and
from them deposited into a tin can, from which it is taken to the combs
or gill boxes as may be desired, making much more even and better
work with less waste and a great saving of labour, as when two lines of
cards are arranged conveniently close together and each row connected
with this improvement one hand or help can overlook both rows of cards,
although there are six or more cards in each row!

can E.
"A" represents the frame of the delivery head, which is constructed as
is shewn in the Drawings with three pairs of rollers R, R¹, R". The
pairs R and R¹ are fluted as is shewn in section in Fig. 3, and the top
roller of each pair is larger than the bottom one. The bottom roller of
pair R¹ has an endless apron W, which may be made of leather or heavy
cotton duck cloth. The rollers of the pair R" are plain and both of the
same size, and are used principally to deliver the sliver into the tin
The journals of the three pairs of rollers are fitted in slotted
stands and adjusted by screws and open spiral springs, as is now used on
the draw rolls of the gill box. The stands F are made so that they can
be adjusted closer together or further apart as may be desired. "B" is the
endless apron, which is mounted on rollers "V" and "O," one at each end
of the trough "H." In this trough are three pairs of rollers S, S¹,

(shewn in sec., Figure 1). The apron B is driven by belt "K" from the
pulley V¹ on one end of the shaft of the bottom roller of the pair
"R."
D, D, are the doffers of the cards which are arranged in a straight line;
C represents the sliver as it is taken from the doffers of the cards. This
sliver is guided by a small funnel to the rollers S and S', which deliver
it to the endless apron B.
The operation is as follows:-The sliver is delivered to the endless
apron B, which carries it forward to the first pair of rollers R, which
deliver it to the second pair R', which pair runs faster than the first pair
to draw the fibres somewhat. This speed may be varied to draw it more
or less. The second pair of rollers R¹ deliver the sliver to the third
pair R", which deliver it into the tin can E. Motion is communicated
to the head through shaft N, and on this shaft is a large spur wheel
gearing into other wheels that communicate motion to the three different
pairs of rollers. These gears are only shewn by the dotted lines in
Figure 1. The endless apron W on the bottom roller R¹ may be dispensed
with by having the top rollers R, R', plain and covered with leather, the
bottom rollers being fluted fine.
Having thus described the nature and particulars of the Invention
communicated to me by the within-named John and James Dobson I
,

page_text: declare that I claim in preparing wool on cards for combing and
delivering the sliver from a number of cards through one delivery the
combination of endless apron B and a delivery head composed of three
pairs of rollers R, R³, and R", as shewn and described.
In witness whereof, I, the said Henry Bernoulli Barlow, have
hereto set my hand and scal, the Twenty-ninth day of June,
One thousand eight hundred and seventy-four.
