Year: 1855

page_text: LETTERS PATENT to Henry, Bernoulli Barlow, of the City of Manchester,
Patent Agent,. for the Invention of "IMPROVEMENTS IN CERTAIN PARTS OF
MACHINES USED IN SLUBBING AND ROVING. COTTON AND OTHER FIBROUS
MATERIALS." A communication.
Scaled the 31st July 1855, and dated the 11th June 1855.
PROVISIONAL SPECIFICATION left by the said Henry Bernoulli Barlow
at the Office of the Commissioners of Patents, with his Petition, on the
11th June 1855.
I, HENRY BERNOULLI BARLOW, of the City of Manchester, Patent Agent, do
hereby declare the nature of the said Invention" for "IMPROVEMENTS IN CERTAIN
PARTS OF MACHINES USED IN SLUBBING AND ROVING COTTON AND OTHER FIBROUS
MATERIALS," (a communication,) to be as follows:
This Invention consists in an improved mode of constructing in giving
pressure to the pressers of flyers, and in guiding the roving or slubbing from
the flyer leg on to the bobbin. The presser is rivetted to or made of the same
piece as the leg, to which is attached a spiral spring for giving the requisite
pressure. The upper end of the spring passes through a bush fixed to the
flyer leg, and the tension of the spring can be varied by withdrawing the end
thereof from the bush and re-inserting it after coiling up or uncoiling the
spring The roving or slubbing, instead of being twisted round the presser, is

page_text: conveyed direct from the flyer leg to the orifice, which is made to open at
the end instead of at the upper surface of the presser. In winding the roving
or slubbing on the spool, it is desirable to make the spool overrun the flyer.
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 10th December 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BERNOULLI BARLOW, of the City of Manchester, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of June, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth 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, administrators, and assigns, or such
others as J, 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 and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN CERTAIN PARTS OF MACHINES USED IN SLUBBING
AND ROVING COTION AND OTHER FIBROUS MATERIALS," which Invention has been
"communicated to me from, abroad, upon the condition (amongst others) that I,
the said Henry Bernolli Barlow, by an instrument in writing under
my hand
and seal, 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 Specification thereof, reference being had to the accompanying
Drawing (that is to say):-
The nature of the said Invention consists, first, in constructing the pressers.
of flyers used in slubbing and roving frames of an improved shape.
Secondly, in an improved mode of giving pressure to the pressers of flyers.

page_text: Thirdly, in an improved mode of increasing or diminishing the pressure of
the spring acting on the presser.
And, lastly, in making the spool revolve in the same direction, but faster than
the presser...
And in order that this Invention may be fully understood and readily carried
into effect, I will proceed to describe the said Drawing, in the several views of
which similar parts are marked with similar letters of reference.
Figure 1 is an elevation of a flyer of the ordinary construction, to which
the improvements above referred to are applied; Figures 2 and 3 are two
other elevations; and Figure 4, a plan of the same.
In these views, a is part of an ordinary spindle, furnished with a spool b
and flyer c of the usual construction; d is the. presser which guides the roving
or slubbing from the flyer leg to the spool b. The opening in the presser
through which the roving passes is made in the end of the presser instead of at
-the upper side thereof, as is now customary; and the roving, instead of being
wound once or more times round the presser before it enters the said opening,
is conveyed direct from the flyer leg to the opening, as shewn in Figures
3 and 4. The presser is either forged with or rivitted to the shank e, sup-
ported.in.the.bearings f and g attached to the flyer leg. The shank_e_which
projects above the bearing f is soldered or otherwise attached to the lower
end of the wire spring g', the upper end of which is secured by the bush h.
The spring gives the requisite pressure to the presser for winding the rovings
on the spool b, and this pressure, owing to the great length of the wire'
The tension of the spring, and con-
composing the spring, is very uniform.
sequently the pressure on the spool, can be regulated with great facility by
withdrawing the end of the spring g' from the bush h, and re-inserting it
again after having coiled or uncoiled the spring.
On referring to Figure 4, it will be seen, by the arrows, that the spool and
the flyer move in the same direction; but in order to make the presser lay the
roving on to the spool in the proper direction, the spool revolves faster than
the presser, consequently the roving on leaving the presser is conveyed again
towards the flyer leg, from whence it is taken to the presser. From this it
will be apparent that the roving, after being guided into the opening of the
presser by the attendant, is not able to get out again unless it breaks, as it
otherwise would do, if the presser revolved faster than the spool; and as
sufficient drag or friction is obtained without winding the roving round the
presser, it is evident that less time is required for piecing up than in pressers
of the ordinary construction.

page_text: I wish to observe that the sping marked g¹ and the shank e may be
made of the same piece of wire, but the mode of construction described is
preferred.
Having thus described the nature of the Invention as communicated to me,
and the manner of performing the same, I wish it to be understood that the
improvements above referred to may be used independently of each other
instead of combined, as shewn, and that what I claim is,-
First, the improved shape of presser shewn and described.
Secondly, the improved mode of giving pressure to the pressers as described.
Thirdly, the improved mode of increasing or diminishing the pressure on
pressers as described.
And, lastly, causing the spool to revolve in the same direction, but faster
than the presser, for the purposes described.
In witness whereof, I, the said Henry Bernoulli Barlow, have hereunto
set my hand and seal, this Eighth day of December, in the year of
our Lord One thousand eight hundred and fifty-five.
M. B. BARLOW. (L.S.)
