page_text: LETTERS PATENT to Peter McGregor, of the Falcon Works, in the City
.
of Manchester, Machine Maker, and Thomas Marquis, of Huncoat, near
Accrington, in the County of Lancaster, Spinner, for the Invention of
CODMATH LURROWEMPTING IN MACHINES FOR SPINNING CALLED THROSTITO "
PROVISIONAL SPECIFICATION left by the said Peter McGregor and
Thomas Marquis at the Office of the Commissiouers of Patents, with
their Petition, on the 2nd April 1856.
We, PETER MCGREGOR, of the Falcon Works, in the City of Manchester,
Machine Maker, and THOMAS MARQUIS, of Huncoat, near Accrington, in the
County of Lancaster, Spinner, do hereby declare the nature of the said
Invention for CERTAIN IMPROVEMENTS IN THE MACHINES FOR SPINNING CALLED
THROSTLES,' to be as follows:-
Our Invention consists in supporting the bobbins on a strip or rail of wood,
iron, leather, gutta percha, or other suitable material, covered with flannel or
other suitable material. This rail lies upon the copping rail, and is moved
longitudinally to and fro by any suitable mechanism, so as to change the
surface on which the bobbins rest. By this means the friction of the bobbins
and the winding-on of the yarn is rendered more uniform and regular than by
the means hitherto adopted.
Another part of our Invention consists in driving the spindles by means of

page_text: vertical drums placed at any convenient distance apart, and driven by gearing
in the same manner as the drums of mules. By this arrangement we are
enabled to increase the diameter of the drums and of the wharves on the
spindles, consequently obtaining greater friction and regularity in the velocity
of the spindles. The same band may be made to drive one spindle at each
side of the throstle, or each spindle may be driven by a separate band, or
several spindles may be driven by the same band, as in mules.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Peter McGregor and Thomas Marquis in the Great Seal
Patent Office on the 2nd October 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, PETER
MCGREGOR, of the Falcon Works, in the City of Manchester, Machino
Maker, and THOMAS MARQUIS, of Huncoat, near Accrington, in the County of
Lancaster, Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of April, in the year of our Lord One
thousand eight hundred and fifty-six, in the nineteenth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto us, the said Peter
McGregor and Thomas Marquis, Her special license that we, the said
Peter McGregor and Thomas Marquis, our executors, administrators, and
assigns, or such others as we, the said Peter McGregor and Thomas Marquis,
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 CERTAIN IMPROVEMENTS IN THE MACHINES
FOR SPINNING CALLED "THROSTLES," upon the condition (amongst others) that we,
the said Peter McGregor and Thomas Marquis, 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.
NOW KNOW YE, that we, the said Peter McGregor and Thomas
Marquis, do hereby declare the nature of our said Invention, and in what

page_text: manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement (that is to say):
The nature of our said Invention consists in giving a longitudinal to-and-
fro motion to a strip or rail of wood, iron, leather, gutta percha, or other
suitable material, covered with flannel or other suitable material, on which the
bobbins are supported, for the purpose of producing a uniform friction between
the bobbin and the flannel or other material.
Secondly, our Invention consists in driving the spindles by means of bands
passing round vertical druins driven by a horizontal shaft and gearing.
And in order that our Invention may be fully understood, and readily
carried into effect, we will proceed to describe the means pursued by us,
reference being had to the accompanying Sheet of Drawings, and to the
figures and letters marked thereon.
Fig. 1 is an elevation, Fig. 2 is a front view, Fig. 3 a transverse section,
and Fig. 4 a plan, of the principal parts of a machine for spinning, called a
"throstle," to which our improvements are applied. a is the main driving
shaft; b, the drawing rollers; c, the spindles; d, the lifting rail; e, tho'
stationary rail; and f the guide pillars for the lifting rail. These and all the
other parts requisite to complete the machine, and not particularly referred to
hereafter, are made in the usual manner. In Figs. 1 and 4 we have shown
two modes of giving longitudinal to-and-fro motion to the strips marked g, g.
In building a machine it is obvious that the same móde will be adopted on
both sides of the machine. We prefer to make these strips of thin sheet
iron, but any other suitable material may be adopted. When sheet iron is "
employed the flannel or other material for giving friction to the bobbins is
secured to the rails by clips soldered on the edges of the strip, or the slot holes
should be punched from the under side, so that the rough edges of the slots
may hold the flannel or other material. When the strip is of wood, leatlier; or
other material, needle points are inserted for the same purpose, or the strip may
be covered with a thin coating of cinery. The end of each strip is attached
by rivets or otherwise to the plates i, i, which have projecting ribs fitting on
each side of the lifting rail d. The strips 9 and the flannel or other material
upon them have slot holes, as shown in Fig. 4, to admit the spindles, and to
allow for the to-and-fro motion of the strips g; this motion is imparted to the
strip g at the left-hand side of Fig. 1 in the following manner :-Upon the
ordinary heart or lifting shaft is fixed, the pinion gearing into the wheel (2
fixed or cast to the scroll P, scen best in Fig. 4, which gives a vibrating
motion to the horizontal lever m, the left-hand end of this lever gives motion
to the vertical lever m'. the upper end of which acts on the lever m² fitting
D

page_text: on the end of the left-hand guide pillar f. The outer end of the lever m³ has
a slot fitting on a stud projecting from one of the plates i, to which the strip g
is attached. By this arrangement the strip g is moved longitudinally to and
fro along the lifting rail, once for every three or four lifts of the lifting rail,
according to the diameters of the wheel and pinion P. At the right-hand
side of Fig. 1 we have shown another mode of giving the to-and-fro motion
to the strip g. In this instance the elbow lever n fits on the end of the right-
hand pillar guide f, and the inclined plane n' is fixed to the end frame; the
other arm of the elbow lever n is furnished with a slot fitting on a stud pro-
jecting from the plate i, consequently as the lifting rail moves up and down,
the inclined plane, acting on the elbow lever n, moves the strip ġ in the
direction of the arrow in Fig. 4; the strip is moved in the contrary direction
by the spring o, seen best in Fig. 2, which acts on the lever o¹, the upper end
of which passes through. a slot in the plate i. This plate and the corresponding
one at the opposite side of the machine are held by screws tapped into the
lifting rail. When the strips g at both sides of the machine are worked by
a vertical lever; like m¹, it is evident that the right-hand extremity of the
lever m is made to communicate the requisite motion to a second vertical
lever m¹ placed at the right-hand side of the machine.
Our improvements in driving the spindles is seen best in the transverse
section, Fig. 8, and in Figs. 2 antl 4. The main shaft a, on which are tho
fast pulley a¹ and loose pulley a², extends the whole length of the machine.
Upon it are keyed the bevel pinions a³ gearing into pinions 9 fixed on the
upright shafts q', to which the drums 92 are attached. The wharves c¹ aro
fixed to the spindles c, as shewn at the left-hand side of Fig. 2, in diagonal
lines, in the same manner as in mules. The bands for driving the spindles
are each taken round two wharves, as shewn best in Fig. 4, that is to say,
the band after passing round the wharve on the first spindle passes round
that on the seventh; the band from the second goes to the eighth, and so on,
for driving twelve spindles at each side of the machine by the saine drum.
A greater number of spindles may be driven by the same drum by increasing
the distance between the lifting rail d and the stationary rail e, so as to obtain
more height for the wharves. In Fig. 3 we have shown the six upper bands
for driving the twelve spindles at the left-hand side of the machine, and the
six lower bands for driving the twelve spindles at the right-hand side of the
machine. This arrangement of the bands may be varied, if desirable, but it is
found most convenient in practice. At the right-hand end of the machine in
Figs. 2 and 4 we have shewn the mode of driving each spindle separately; in
this instance ouly twelve spindles are driven by one drum . The foregoing

page_text: description and the Drawings are sufficient to illustrate this part of our
Invention; but it is evident that this mode of driving the spindles may be
modified, the same band may be made to drive one spindle at each side of
the machine, or several spindles may be driven by the same band, as in
mules.
Having thus described the nature of our Invention, and the manner of
performing the same, we wish it to be understood, in reference to the first part
of our Invention, that we make no claim to self-acting machinery for giving
motion to the flannel or other material for imparting friction to the bobbins,
as the same has before been made public; but what we do claim is,-
First, giving a longitudinal to-and-fro motion to the strips g, covered with
flannel or other suitable material for giving the required friction to the
bobbins.
And, secondly, driving the spindles of throstles by means of bands and
drums, as herein-before shewn and described.
In witness whereof, I, the said Peter McGregor, have hereunto set my
hand and seal, this First day of October, in the year of our Lord One
thousand eight hundred and fifty-six.
PETER MCGREGOR. L.S.)
