Year: 1862

page_text: LETTERS PATENT to James Milner, Robert Dawson Milner, and Frederick
Hurd, all of Wakefield, in the County of York, Machinists and Co-
partners, for the Invention of "IMPROVEMENTS IN APPARATUS APPLICABLE TO
MACHINES FOR PREPARING WOOL, FLAX; AND OTHER FIBROUS SUBSTANCES,
PROVISIONAL SPECIFICATION left by the said James Milner, Robert
Dawson Milner, and Frederick. Hurd at the Office of the Commissioners
of Patents, with their Petition, on the 26th September 1862:
We, JAMES MILNER, ROBERT DAWSON MILNER; and FREDERICK HURD, all
of Wakefield, in the County of York, Machinists and Copartners; do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN APPARATUS
APPLICABLE TO MACHINES FOR PREPARING WOOL, FLAX, AND OTHER FIBROUS
SUBSTANCES, PARTS OF WHICH ARE ALSO APPLICABLE TO MACHINES FOR OTHER USES;"
to be as follows -
Our Invention has for its object the regulation of the "drag" in the passing
of the sliver of wool or other material from the front drawing roller to the
bobbin by means of friction discs; in substitution for the apparatus ordinarily
employed for this purpose.
In order to accomplish the said object there are two disës, one fixed on the
ordinary driving shaft, and the other on the shaft which works the "drag,"
and the traversing motion, such dises corresponding with the ordinary speed
cones; and there is an intermediate disc or pair of discs; which is or aro

page_text: moved up and down in the direction of a line passing through the centres of
the said two shafts by the action of the ordinary catch wheel and weight on a
screw or other suitable mechanism. The pair of intermediate discs embrace
a portion of the face of the two stationary discs between them, and they are
kept in contact therewith by means of a spring and socket. By this arrange-
ment the said intermediate discs by being moved over the face of the two
stationary discs are caused to change as required the speed of the discs on the
shaft which works the "drag" and traversing motion, and are thus used in
substitution for the ordinary strap belonging to the ordinary conical speed
pulleys.
The above described arrangement of two stationary discs and a pair of
intermediate moveable discs may also be adapted to other machines besides
those used for preparing fibrous substances in substitution for the ordinary
conical speed pulleys and strap.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Milner, Robert Dawson Milner, and Frederick Hurd
in the Great Seal Patent Office on the 26th March 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
MILNER, ROBERT DAWSON MILNER, and FREDERICK HURD, all of Wakefield, in
the County of York, Machinists and Copartners, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of September, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said James Milner, Robert Dawson Milner, and Frederick Hurd,
Her special license that we, the said James Milner, Robert Dawson Milner,
and Frederick Hurd, our executors, administrators, and assigns, or such
others as we, the said James Milner, Robert Dawson Milner, and Frederick
Hurd, 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
APPARATUS APPLICABLE TO MACHINES FOR PREPARING WOOL, FLAX, AND OTHER
FIBROUS SUBSTANCES, PARTS OF WHICH ARE ALSO APPLICABLE TO MACHINES FOR
OTHER USES," upon the condition (amongst others) that we, the said James

page_text: Milner, Robert Dawson Milner, and Frederick Hurd, by an instrument in
writing under our hands and seals, or under the hand and seal of one of us,
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 we, the said James Milner, Robert Dawson Milner,
and Frederick Hurd, 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, reference being had to the
Drawings hereunto annexed, and to the letters and figures marked thereon
(that is to say) :-
Our Invention has for its object the regulation of the "drag" in the
passing of the sliver of wool or other material from the front drawing roller to
the bobbin by means of friction dises in substitution for the apparatus ordinarily
employed for this purpose.
cones.
In order to accomplish the said object there are two discs, one fixed on the
ordinary driving shaft, and the other on the shaft which works the "drag"
and the traversing motion, such discs corresponding with the ordinary speed
And there is an intermediate disc, or pair of discs, which is, or are
moved up and down in the direction of a line passing through the centres of
the said two shafts by the action of the ordinary catch wheel and weight on a
screw or other suitable mechanism. The pair of intermediate discs embrace
a portion of the face of the two stationary discs between them and they are
kept in contact therewith by means of a spring and socket. By this arrange-
ment the said intermediate discs by being moved over the face of the two
stationary discs are caused to change, as required, the speed of the disc on
the shaft which works the "drag" and traversing motion, and are thus used
in substitution for the ordinary strap belonging to the ordinary conical speed.
pullies.
The above described arrangement of two stationary discs and a pair of
intermediate moveable discs may also be adapted to other machines, besides
those used for preparing fibrous substances, in substitution for the ordinary
conical speed pullies and strap.
Having thus stated the nature of the said Invention, we will proceed to
describe more particularly in what manner the same is to be performed, by
reference to the accompanying Drawings, in which is represented so much of
a machine of the kind referred to as is sufficient to shew the mode of applying
our improvements thereto.

page_text: Fig. 1 is a vertical section, and Fig. 2 a side view of part of a machine
with our improvements applied thereto. In these two Figures the same
'letters of reference indicate corresponding parts.
A, A, is the ordinary frame or standards of the machine; B is the driving
shaft; C is a driving disc screwed to the shaft as shewn, or it may be otherwise
fixed thereto; D is a similar disc fixed to the shaft E which works the "drag"
and the traversing motion. These two discs correspond with the ordinary
speed cones. They are made in halves, as shewn at D, in order to secure
lightness. F, F, are a pair of intermediate discs by means of which the
motion is conveyed from the driving disc C to the disc D on the shaft E.
These intermediate discs are pressed against the sides of the two discs C and D,
by means of the spiral spring G and the nut H on the socket and washer I,
which being of a convex form allow the intermediate discs F, F, to adapt
themselves to the sides of the discs C and D, and thus preserve an uniform
pressure as they are moved over the faces of these discs. The socket I, and
intermediate discs F, F, revolve on the pin J, which is fixed in a bracket K,
and they are moved in the direction of a line passing through the centres
of the discs C and D, as shewn by the line a, b, in Fig. 2. This motion
of the intermediate discs is produced by means of the screw L, acted upon
by the ordinary weight and catch wheel, or it may be produced by means of
other suitable mechanism. It will be seen from the lines c, d, Fig. 1, that
the sides of the discs C, D, are tapered in width with relation to the
distance of the shafts A and E apart from each other, that is to say, in such
a. manner that the converging lines meet in a point midway between the
two shafts. In this manner an uniformity of width of the two discs C and D,
at the points of contact M, M, is preserved, and by that means a corre-
sponding uniformity of power is maintained when the positions of such points
of contact are changed. It will be observed that these points of contact
of the intermediate discs with the two discs C and D are rounded for the
purpose of diminishing friction. The ordinary connection between the shaft E,
and the "drag" and traversing motion, by means of spur and bevil gear,
is shewn at N, and in this manner the required "drag" is applied to the
drag plate O (Fig. 2) being regulated by the intermediate discs F, F, which
are caused to move over the faces of the discs C and D in an upward direction.
It will thus be evident that by causing the intermediate discs to be moved
over the faces of the stationary discs C and D, the speed of the shaft e,
which works the "drag" and traversing motion, will be changed as required,

page_text: This arrangement of two stationary discs combined with a pair of intermediate
moveable discs, in substitution for the ordinary conical speed pullies and
strap, is applicable to a machine with only two spindles, and admits of the
machine being reduced in size. It is also applicable to other machines
besides those used for preparing fibrous substances.
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, we hereby declare that what we claim
as of our Invention is, the combination of parts of apparatus whereby the
speed of the shaft which works the "drag" and the traversing motion or
other differential motion is changed as required by means of a pair of
intermediate discs moved over the faces of two stationary discs as herein-before
described.
In witness whereof we, the said James Milner, Robert Dawson Milner,
and Frederick Hurd, have bereunto set our hands and seals, the Twenty-
fourth day of March, in the year of our Lord One thousand eight
hundred and sixty-three.
o Witness,
JAMES MILNER.
