page_text: LETTERS PATENT to William Hoyle, of Greenhill Terrace, Greenhill;,.
Oldham, in the County of Lancaster, Machinist, for the Invention of
"CERTAIN IMPROVEMENTS IN MACHINERY FOR. PREPARING, SPINNING, AND.
DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES."
Sealed the 16th October 1861, and dated the 2nd May 1861.
PROVISIONAL SPECIFICATION left by the said William Hoyle at the
Office of the Commissioners of Patents, with his Petition, on the 2nd
May 1861.
I, WILLIAM HOYLE, of Greenhill Terrace, Greenhill, Oldham, in the County
of Lancaster, Machinist, do hereby declare the nature of the said Invention.
for "CERTAIN IMPROVEMENTS IN MACHINERY FOR PREPARING, SPINNING, AND,
DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES," to be as follows:-
My Invention is applicable to all the machines used in preparing, spinning,
and doubling, in which drawing rollers are employed, and it consists in certain.
improved arrangements of parts for applying pressure to the top rollers of the
drawing rollers.
In performing my Invention I employ an endless band; either flat or round;.
which passes over the top roller and under a pulley, to which is suspended a.
hook for the weight, or which is supported in a weighted lever; or connected.
direct to the weight; when the top roller revolves it causes the pulley to
revolve also, and the axle of this pulley is either guided in a slotted bracket
fixed under or above the roller beam, or it is allowed to work free.

by the said William Hoyle in the Great Seal Patent Office on the
1st November 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HOYLE, of Greenhill Terrace, Greenhill, Oldham, in the County of Lancaster,
Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of May, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Hoyle, Her special licence that I, the said William Hoyle, my
executors, administrators, and assigns, or such others as I, the said William
Hoyle, 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 "CERTAIN IMPROVEMENTS IN MACHINERY
FOR PREPARING, SPINNING, AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES,"
upon the condition (amongst others) that I, the said William Hoyle, my exe-
cutors 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 William Hoyle, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol-
lowing statement (that is to say) :-
My Invention is applicable to all the machines used in preparing, spinning,
and doubling in which drawing rollers are employed, and it consists in certain
improved arrangements of parts for applying pressure to the top rollers of the
drawing rollers.
And in order that my Invention may be fully understood, and readily carried
into effect, I will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Figure 1 is an elevation, in section, of part of a drawing frame, to which my
improvements are applied; Figure 2 is a side view of the same.
a, a, are the

page_text: fluted drawing rollers, and 6 the roller beam; these parts are constructed as
usual; the top rollers c are furnished with recesses near each end, as shewn in
Figure 2, for the endless bands or straps d to pass over; these bands may be
either flat or round, but I prefer the former, and they pass through slots in the
roller beam and under the pulleys e, to the axles of which are suspended the
hooks f, cast in or passing through the weights g; these weights are all shewn
of the same size, but it is evident that they may be of different sizes to suit the
work. The straps d are of two lengths, in order to bring the pulleys e on
different levels, thereby giving more room for the said pulleys. By means of
this improved arrangement the pressure on the top rollers is obtained with less
friction than usual, as the friction of the ordinary weight hooks is avoided, and
-the only friction to be overcome is that due to the hooks f, on the axles of the
pulleys e; the advantages obtained are a more equal pressure on the top
rollers, and a considerable reduction in the weights employed.
Figures 3 and 4 represent a modification of my improvements; as the parts
in themselves are similar to those above referred to, they are marked with corre-
sponding letters of reference. In these views the straps d are considerably
shorter, and the rollers e are placed above the roller beam 6; the rollers e are
all on the same level, as shewn in Figure 3, but on referring to Figure 4 it
will be seen that some of the top rollers are weighted by straps near each end,
while others are weighted from the centre; this arrangement is necessary to
give room for the pulleys e.
Figures 5 and 6 are two views of another modification of my Invention; in
these views the improvements are only applied to the front drawing rollers
of the set of drawing rollers, and the pulley e is placed above the roller beam;
the hook passes through the lever k, which is jointed to.a stud fixed in the
roller beam, and to the lever k is suspended the weight g. By varying the
position of the weight on the lever the pressure on the top roller can be
regulated.
Figure 7 represents a mode of applying my improvements to front drawing
rollers of a throstle or other machine in which a clearing roller is applied to the
under side of the drawing roller. The clearing roller is marked i, and the
strap & passes under the two pulleys e, which are supported in the frame j, to
which the weight hook is suspended.
Figure 8 is another modification of my improvements; in this arrangement
the pulleys e, for two of the weight straps d, and top rollers c, are mounted in
the frame 1, to which is suspended the hook f for the weight g.
Having thus stated the nature and particulars of my Invention, and shewn
several modes of performing the same, I wish it to be understood that I do not

page_text: intend to limit the application thereof to the particular machines referred to in
the above description, as my improvements are equally applicable to all the
machines used in preparing, spinning, and doubling cotton and other fibrous
substances, in which weighted top rollers are employed, nor do I confine
myself to the details set forth, as they may be considerably varied or modified
without departing from the peculiar character thereof; but what I claim is,.
the application of pressure to top rollers by means of a weight, which remains
stationary while the endless band revolves round the top roller and round a
pulley or pulleys, to which the weight is suspended or connected, as shewn and
described.
In witness whereof, I, the said William Hoyle, have hereunto set my
hand and seal, this Thirtieth day of October, in the year of our
Lord One thousand eight hundred and sixty-one.
WILLIAM HOYLE. (L.S.)
