Year: 1866

page_text: LETTERS PATENT to Prince Smith, the elder, of Keighley, in the County
of York, Gentleman, for the Invention of "IMPROVEMENTS IN WEIGHTING
TOP-PRESSING ROLLERS FOR DANDY-ROVING AND SPINNING OF WOOL, WORSTED,
"
PROVISIONAL SPECIFICATION left by the said Prince Smith at the
Office of the. Commissioners of Patents, with his Petition, on the 19th
February 1866.
I, PRINCE SMITH, the elder, of Keighley, in the County of York, Gentleman,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN WEIGHTING TOP-PRESSING. ROLLERS FOR DANDY-BOVING AND SPINNING OF WOOL,
WORSTED, SILK, MOHAIR, ALPACA, AND OTHER FIBROUS SUBSTANCES," to be as
follows:-
My Invention relates to a means of applying or, distributing the weight
more equally and effectually than by the ordinary method, whereby a great
saving of power is obtained, and also a considerable economy of the leather and
cloth with which the rollers are covered is effected.
My Invention consists of a double" hanger" composed of a bar of metal
bent or formed in the shape of an elongated letter U, the ends being, screwed
and furnished with finger nuts and helical springs. These springs act upon a

page_text: bush or cap of steel, wrought-iron case hardened, or other suitable metal, through
which the hanger passes at right angles, and which presses against the journal
of the roller, so that the pressure being evenly distributed on both sides of the
roller acts more equally and effectually upon the latter, diminishes the wear
and tear thereof, and enables them to draw the wool, worsted, silk, mohair,
alpaca, or other fibrous substance more effectually than when weighted by
means of the single hanger hitherto employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Prince Smith in the Great Seal Patent Office on the
18th August 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PRINCE
SMITH, the elder, of Keighley, in the County of York, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date, the Nineteenth day of February, in the year of our
Lord One thousand eight hundred and sixty-six, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Prince Smith, the elder, Her special licence that I, the said Prince
Smith, the elder, my executors, administrators, and assigns, or such others as
J, the said Prince Smith, the elder, 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 WEIGHTING TOP-PRESSING ROLLERS FOR DANDY-ROVING AND
SPINNING OF WOOL, WORSTED, SILK, MOHAIR, ALPACA, AND OTHER FIBROUS
SUBSTANCES," upon the condition (amongst others) that I, the said Prince
Smith, the elder, 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 Prince Smith, the elder, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following

page_text: Statement in writing, and on reference to the accompanying Sueet of Drawings,
that is to say-
My Invention relates to a means of applying or distributing the weight
more equally and effectually than by the ordinary method, whereby a great
saving of power is obtained and also a considerable economy of the leather and
cloth with which the rollers are covered is effected.
ة
My Invention consists of a double "hanger" composed of a bar of metal
bent or forined in the shape of an elongated letter U, the ends being screwed
and furnished with finger nuts and helical springs. These springs act upon
bush or cap of steel, wrought iron, case-hardened, or other suitable métal
through which the hanger passes at right angles, and which presses against
the journal of the roller, so that the pressure being evenly distributed on both
sides of the roller acts more equally and effectually upon the latter, diminishes
the wear and tear thereof, and enables them to draw the wool, worsted, silk,
mohair, alpaca, or other fibrous substance more effectually than when
weighted by means of the single hanger hitherto employed.
Such being the nature and object of my said Invention for "Improvements
in Weighting Top-pressing Rollers for Dandy-roving and Spinning of Wool,
Worsted, Silk, Mohair, Alpaca, and other Fibrous Substances," I will now
proceed to describe more in detail the manner in which the same is to be or
may be performed or carried into practical effect; and in order that the same
may be distinctly understood I have annexed hereunto a Sheet of Drawings
illustrative thereof, and have marked the same with figures and letters of
reference corresponding with those in the following explanation thereof, that
is to say:
In the annexed Drawing, Figure 1 represents a side view of the ordinary
single hanger as hitherto employed. a, a, is the hanger formed with a hook at
the bottom, which passes through a notch or slot in the arm 6 of the saddle
bar c; and d, d, is the cap through which the upper part of the hanger
passes, and which is hollowed underneath so as to partially embrace the axis
of the top roller e, e. The upper part of the hanger is screwed and provided
with a finger nut f, f, beneath which is a helical spring 9, 9, coiled round the
hanger and pressing against the top of the cap d, d. The pressure between
the two rollers is increased or diminished by tightening or slackening the
nut f, f. It will be evident that as this pressure does not act equally upon
both sides of the axis of the top roller it acts at a great disadvantage and the
weight is unevenly distributed.
Figure 2 shows my improved double banger. The hanger a, a, is composed
or formed of a bar of metal bent or formed as before mentioned, the two arms

page_text: being perpendicular and parallel to each other. The cap d, d, of steel,
wrought iron, case-hardened, or other suitable metal, is placed at right angles
to the hanger, and is furnished with two holes through which the ends of the
banger pass, a curved notch being formed in the centre of its lower side to
bear against the axis of the top roller e, e; the lower part of the hanger a, a,
is supported by an arm b, springing from the front saddle bar c, in the end of
which arm a notch or slot is made through which the hanger passes. The
lower part of the hanger a, a, may be also supported by any other fixture
that may be made available for the purpose. The two ends of the
hanger a, a, are both screwed, and are each furnished with a screw nut f,f,
and a helical spring 9, 9, bearing on the top of the cap d, d. It will
be evident that by this arrangement the pressure will be caused to act
equally upon both sides of the axis of the top roller, and thus the weight will
be distributed more equally and effectually than by means of the ordinary
single hanger previously described, and hence the wear and tear of the rollers
will be diminished and the drawing of the wool or other fibrous substance
will be more effectually performed.
Having now described the nature and object of my said Invention for
"Improvements in Weighting Top-pressing Rollers for Dandy-roving and
Spinning of Wool, Worsted, Silk, Mohair, Alpaca, and other Fibrous Sub-
stances," together with the manner in which the same is to be or may be
performed or carried into practical effect, I would remark in conclusion that I
claim as my Invention the double hanger and cap substantially as above
described for the purpose of distributing the weight more evenly upon the
rollers in the manner and for the purposes herein-before set forth.
In witness whereof, I, the said Prince Smith, the elder, have hereunto
set my hand and seal, this Sixteenth day of August, in the year of
our Lord One thousand eight hundred and sixty-six.
Signed, sealed, and delivered by the
above-named Prince Smith, the
elder, in the presence of
GEORGE BURR,
PRINCE SMITH, SENE. (L.S.)
