page_text: LETTERS PATENT to William Clegg, of Rochdale, in the County of
Lancaster, Carder. Thomas Wild, of the same Place, Manager, and James
Tomlinson, of the same Place, Machine Maker, for the Invention of
"IMPROVEMENTS IN CERTAIN MACHINES FOR PREPARING COTTON AND OTHER
PROVISIONAL SPECIFICATION left by the said William Clegg. Thomas
Wild, and James Tomlinson, at the Office of the Commissioners of
Patents, with their Petition, on the 6th October 1860.
We, WILLIAM CLEGG, of Rochdale, in the County of Lancaster, Carder,
THOMAS WILD, of the same Place, Manager, and JAMES TOMLINSON. of the
same Place, Machine Maker, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN CERTAIN MACHINES FOR PREPARING COTTON AND OTHER
FIBROUS MATERIALS," to be as follows:--
Our Invention is applicable to slubbing frames, roving frames, and other
machines for preparing cotton and other fibrous materials, in which two cones
are employed for varying the speed of the bobbins, according to the increasing
diameter of the rovings wound upon them. or for other purposes where a
variation in speed is required, or where a pulley or cylinder and cone are em-
ployed. and it consists in employing two or more straps for communicating the
motion from one cone to the other, or from the pulley or cylinder to the cone,
instead of employing a single strap, as now customary.
...Price 8.1

page_text: Our Invention also consists in an improved mode of constructing the strap.
guide, by which the straps are traversed to and fro along the cones, so as to
keep the straps at the requisite distance apart when at work.
The improved mode of constructing the strap guide consists in applying
thereto one or more divisions, according to the number of straps employed for
the purpose of keeping them asunder when traversing to and fro.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we. WILLIAM
CLEGG. of Rochdale. in the County of Lancaster. Carder, THOMAS WILD, of
the same Place. Manager. and JAMES TOMLINSON, of the same Place, Machine
Maker, send greeting.
WHEREAS Iter most Excellent Majesty Queen Victoria, by Her Letters
Patent. bearing date the Sixth day of October, in the year of our Lord One
thousand eight hundred and sixty. in the twenty-fourth year of Her reign,
did. for Herself, Her heirs and successors. give and grant unto us, the said
William Clegg. Thomas Wild, and James Tomlinson, Her special licence that
we, the said William Clegg, Thomas Wild, and James Tomlinson,
executors. administrators, and assigns, or such others as we, the said William
Clegg, Thomas Wild, and James Tomlinson, 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 In-
vention for "IMPROVEMENTS IN CERTAIN MACHINES FOR PREPARING COTTON AND
OTHER FIBROUS MATERIALS," upon the condition (amongst others) that we, the
said William Clegg. Thomas Wild, and James Tomlinson. 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 mouths next and immediately after the date of the said Leiters
Patent.
NOW KNOW YE, that we, the said William Clegg, Thomas Wild, and
James Tomlinson, do hereby declare the nature of our said Invention, and

page_text: 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):-
Our Invention is applicable to slubbing frames, roving frames, and other
machines for preparing cotton and other fibrotts materials, in which two cones,
or a pulley, or cylinder and cone, are employed for varying the speed of the
bobbins according to the increasing diameter of the rovings wound upon them,
or for other purposes where a variation in speed is required, and it consists in
employing two or more straps for communicating the motion from one cone to
the other, or from the pulley or cylinder to the cone, instead of employing a
single strap. as now customary.
Our Invention also consists in constructing the strap guide with one or more
divisions, by which the straps above referred to are traversed to keep them at
the requisite distance apart when at work.
And in order that our Invention may be fully understood and readily carried
into effect, we will proceed to describe the accompanying Drawing, reference
being had to the Figures and letters marked thereon.
Fig. is an elevation of the cones of a roving frame of the usual construction
to which our improvements are applied; Fig. 2 is a section of the same;
and Fig. 3 is a plan of the improved strap guide.
a is the upper cone; b, the lower cone; and c, the rod or bar to which the
strap guides are attached; this rod or bar is traversed to and fro in the
ordinary manner to move the strap guides from one end of the cones to
the other. It has heretofore been customary to employ a broad strap to com-
municate motion from the upper to the lower cone; this broad strap is
objectionable, as it imparts an irregular motion, and requires a considerable
force to move it to and fro along the cones; it is also difficult to adjust it
to the proper length; now our Invention consists in obviating these defects by
substituting two or more narrow straps in lieu of a single broad one; in the
present instance we have shewn three siraps e, e, e. the combined widths of
which are about equal to the usual broad strap, but we do not intend to limit
ourselves to the use of three straps, as in some cases two will be found sufficient,
and in others it may be desirable to employ more than three; the strap guides d
are made with two internal divisions marked d' in Fig. 3, .so that each strap e
is guided on both sides. By means of these improvements a great economy
in power is effected, the motion imparted to the lower cone is more regular,
and the to-and-fro motion of the straps can be changed more rapidly than when
the ordinary broad strap is employed. In case a pulley or cylinder should be
used instead of one of the cones shewn in the Drawing, the same arrangement,
of narrow straps and strap guides with divisions can be adopted; we would

page_text: also remark, that although we have only shewn our Invention as applied to a
roving frame, it is equally applicable to slubbing frames and any other machine
employed in preparing cotton and other fibrous materials where two cones or
a pulley or cylinder and one cone are used.
Having thus stated the nature of our Invention and described a convenient
mode of carrying the same into operation, we wish it to be understood that we
do not limit ourselves to the details given, but that we claim as our Invention
the use and application of two or more straps for communicating motion from
one cone to another, or from a pulley or cylinder to a cone, as shewn and
described.
In witness whereof, we, the said William Clegg. Thomas Wild, and
James Tomlinson, have hereunto set our hands and seals, this Second
day of April, in the year of our Lord One thousand eight hundred and
sixty-one.
