IMPROVEMENTS IN WORSTED SPINNING FRAMES
Year: 1869

page_text: LETTERS PATENT to Jonas Priestley Balm, of Halifax, in the County
of York, Worsted Spinner, and Robert Newton, of Providence Mill,
near Keighley, in the same County, Engineer and Machine Maker,
for the Invention of "IMPROVEMENTS IN WORSTED SPINNING FRAMES."
Scaled the 29th October 1869, and dated the 1st May 1869.
PROVISIONAL SPECIFICATION left by the said Jonas Priestley Balm
and Robert Newton at the Office of the Commissioners of Patents,
with their Petition, on the 1st May 1869.
We, JONAS PRIESTLEY BALM, of Halifax, in the County of York,
Worsted Spinner, and ROBERT NEWTON, of Providence Mill, near
Keighley, in the same County, Engineer and Machine Maker, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN WORSTED
SPINNING FRAMES," to be as follows:-
This Invention relates to the carrying rollers of spinning frames,
and the improvements consist in giving a traverse motion or a recipro-
catory endwise movement to the bottom front carrying roller, thus

page_text: producing a frictional sliding of the same against the top roller. Also
in covering one or both of the said front carrying rollers with either
india-rubber, leather, or other suitable substance to produce adhesion on
the rovings as they pass through or between them to the drawing rollers.
By this means we can combine, condense, rub, or roll together the loose
fibres of the said rovings before they enter the drawing rollers, and
thereby we produce a better class of yarn.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Priestley Balm and Robert Newton in the
Great Seal Patent Office on the 1st November 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JONAS
PRIESTLEY BALM, of Halifax, in the County of York, Worsted Spinner,
and ROBERT NEWTON, of Providence Mill, near Keighley, in the same
County, Engineer and Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of May, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Jonas Priestley Balm and Robert
Newton, Her special licence that we, the said Jonas Priestley Balm and
Robert Newton, our executors, administrators, and assigns, or such
others as we, the said Jonas Priestley Balm and Robert Newton,
our 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 WORSTED SPINNING FRAMES," to be as follows, upon the
condition (amongst others) that we, the said Jonas Priestley Balm and
Robert Newton, our executors or administrators, by an instrument in
writing under our, or their, or one of our or 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.

page_text: NOW KNOW YE, that we, the said Jonas Priestley Balm and Robert
Newton, do hereby declare the nature of our 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) :-
-
This Invention relates to the carrying rollers of spinning frames, and
the improvements consist in giving a traverse motion or a reciprocatory
endwise movement of the bottom front carrying roller, thus producing a
frictional sliding of the same against the top roller. Also in covering
one or both of the said front carrying rollers with either india-rubber,
leather, or other suitable substance to produce adhesion on the rovings
as they pass through or between them to the drawing rollers. By this
means we can combine, condense, rub, or roll together the loose fibres of
the said rovings before they enter the drawing rollers, and thereby wo
produce a better class of yarn.
The manner in which this Invention is performed or carried into
practical operation is as follows:-The necks of the bottom front carry-
ing rollers are made wider than their bearings to the extent which it is
found desirable that they should move endwise. A cam wheel.is fixed
on one end of the bottom drawing roller, which as it rotates acts upon a
moveable finger or lever arranged to be in contact with one end of the
said bottom carrying roller, and a spring lever is fixed to the frame at
the other end and acting on the opposite end of the said bottom carrier;
thus the cam operates to move it in one direction and the spring in the
other, whereby a reciprocatory motion thereof is produced. This cam
may be formed of one, two, three, or more lifts in its circumference, so
as to produce any desirable number of reciprocations of the bottom
carrier to one revolution of the drawing roller. These carriers may be
covered with any kind of material that will have more adhesion on the
rovings than iron and wood, of which carriers are usually made; or they
may be slightly corrugated or grooved instead of being plain and
smooth, so as to have more hold on the said rovings, so that by the
reciprocation of the bottom roller they will roll or rub the fibres of the
rovings together, and thus combine and condense them before entering
between the drawing rollers, by which means we are enabled to produce
a better class of yarn than heretofore.
Having thus described the nature of our said Invention, and the
manner in which the same is to be or may be performed or carried into
practical operation, we would have it understood that we do not confine

page_text: or restrict ourselves to the means described of producing this endwise
motion, nor to the moving of the bottom carrier rollers, seeing that
various means may be used for that purpose, and that the top rollers
may be moved endwise if desirable, either instead of or in conjunction
with but in opposite directions to the bottom rollers; what we claim as
our Invention is, the traversing or producing a reciprocatory motion in
addition to the usual rotary motion on one or both of the front carrying
rollers to effect a rubbing or rolling of the rovings when passing betwixt
them, and for the purpose of producing more adhesion we either cover
them with some suitable material or groove them in manner substantially
as explained.
In witness whereof, I, the said Jonas Priestley Balm, for and on
behalf of myself and the said Robert Newton, have hereunto set
my hand and seal, this Thirtieth day of October, in the year of
our Lord One thousand eight hundred and sixty-nine.
Signed, sealed, and delivered
by the within-named Jonas
Priestley Balm, in the
sence of
