Year: 1875

page_text: LETTERS PATENT to Henry Baxter and Luke Rushworth, both of
Hollinwood, and Ucury Clough, of Failsworth, all in the County
· of Lancaster, for the Invention of "IMPROVEMENTS IN
THE CON-
STRUCTION OF SPINNING MULES AND TWINERS FOR SPINNING AND DOUBLING
Sealed the 28th September 1875, and dated the 31st July 1875.
PROVISIONAL SPECIFICATION left by the said Henry Baxter,
Luke Rushworth, and Henry Clough at the Office of the Com-
missioners of Patents, with their Petition, on the 31st July
1875.
WC, HENRY BAXTER and LUKE RUSHWORTH, both of Hollinwood,
and HENRY CLOUGH, of Failsworth, all in the County of Lancaster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF SPINNING MULES AND TWINERS FOR SPINNING AND DOUBLING
COTTON AND OTHER FIBROUS SUBSTANCES," to be as follows.-
-
The object of this Invention is to dispense with the "scrolls" and
"scroll bands" at present employed to give the "taking up" motion to

page_text: the mule carriage, and in their place to substitute a much simpler and
less costly arrangement, consisting principally of a long lever turning
on a pivot and actuated by suitable gearing to give the requisite traverse
to the said carriage.
To the lower end of the "catch box shaft" and at a suitable distance
from the ground is keyed or otherwise fixed a spur pinion, which drives
by any convenient intermediate gearing a spur wheel turning on a stud
fixed to the ground about half way of the traverse of the mule carriage
and opposite the catch box shaft This wheel carries with it in its
revolution the lever before mentioned, which turns on the same stud,
and the spur gearing is so arranged that whilst the "catch box" is in
gear the spur wheel and lever perform nearly half a revolution. To the
end of this lever is attached a bowl or pulley, which works between two
rails, or in a slotted bar attached to the mule carriage, and it will thus
be evident that when the catch box comes into gear the carriage will be
drawn up to the "hoadstock" by the lovor, which is made slightly longer
than half tho traverse of the carriage to avoid getting on a dead
centre.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Baxter, Luko Rushworth, and Henry
Clough in the Great Seal Patent Office on the 31st January
1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, ILENRY
BAXTER and LUKE RUSHWORTш, both of Пollinwood, and HENRY
CLOUGH, of Failsworth, all in the County of Lancaster, send greeting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Hor
Letters Patent, bearing date the Thirty-first day of July, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Henry Baxter, Luke Rush-
worth, and Henry Clough, Her special license, that we, the said Henry

page_text: Baxter, Luke Rushworth, and Henry Clough, our exccutors, admini-
strators, and assigns, or such others as wc, the said Henry Baxter,
Luke Rushworth, and Henry Clough, our exccutors, 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, excrcise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN THE CONSTRUCTION
OF SPINNING MULES AND TWINERS FOR SPINNING AND DOUBLING COTTON AND
OTHER FIBROUS SUBSTANCES," upon the condition (amongst others) that
we, the said Henry Baxter, Luke Rushworth, and Пemy Clough, our
exccutors or administrators, by an instrument in writing under our, or
one of our, 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 Henry Baxter (on behalf of myself
and the said Luke Rushworth and Henry Clough, do hereby declare the
nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings.—
The object of this Invention is to dispense with the "scrolls and
scroll bands at present employed to give the "taking up' motion to the
mule carriage, and in their place to substitute a much simpler and less
costly arrangement, consisting principally of a long lever turning on a
pivot and actuated by suitable gearing to give the requisite traverso of
thic said carriage.
Such being the nature and object of our said Invention we will now
proceed to describe 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 clearly understood we 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 expla-
nation thereof.-
'
Fig 1 in the annexed Drawing is a sectional elevation; and Fig. 2 a
martial plan view of so much of a mulo as
15 NOCOSSY to illustrato 31

page_text: Invention, a, a, being part of the framing of the headstock, and b, b, the
carriage.
To the lower end of the "catch box shaft" c, c, and at a suitable
distance from the ground is keyed or otherwise fixed a spur pinion d, d,
which drives by any convenient intermediate gearing e, e, a spur
wheel, turning on a stud fixed to the ground about half way of the
traverse of the mulo carriage and opposite the catch box shaft. This
wheel carrics with it in its revolution the lever g, g, before mentioned,
which turns on the same stud, and the spur gearing is so arranged that
whilst the catch box h, h, is in gear the spur wheel,f, and lever g, g,
perform nearly half a revolution. To the end of this lever g, I, is
attached a bowl or pulley 2, 2, which works between two lails k, k,
slightly curved by preference, or in a slotted bar attached to the mule
carriage b, b, and it will thus be evident that when the catch box h, h,
comes into gear the carriage b, b, will be drawn up to the " "headstock'
by the lever g, g, which is made slightly longer than half the traverse
of the carriage b, b, to avoid getting on a dead centre.
"
The drawing out of the carriage is performed by the usual weights,
as when the catch box h, h, is out of gear the spur wheels e, e, and S,S,
are easily turned in the reverse direction.
On the wheelf, f, is a stud or pin 1, 1, projecting upwards, and as the
wheelf.f, revolves in running in the carriage this stud comes against a
short lever n, n, turning on the same stud as the long lever g, g, and
causes this lever n, n, to extend the spring o, o, attached to it, and this
spring thus pulling at the wheels, assists the weights in commencing
to draw the carriage out.
It will be evident that a large wheel or disc could carry the bowl with
the same effect as the lever g.
The hinder or holding back bar for preventing the carriage over-
running entirely the lever 9, 9, may be made to turn on a centre at one
end regulated by a set screw, as shown on the Drawing, the other end
bedding against a fixed piece, which receives the bowl when the carriage
has run out to the fullest extent
The object of pivoting the holding back bar is to compensate for
different speeds of the engine, the carriage b, b, running in quicker
when allowed slightly to overrun the lever g, g.

page_text: While the mule is spinning, the lever being on a dead centre (sec
dotted line in Fig. 2), it is evidently impossible for the carriage to
commence to run in until the catch box d, d, comes into gear; thus the
ordinary holding out catches and the gear for working them may be
dispensed with.
Having now described the nature and object of our said Invention,
together with the manner in which the same is to be or may be
performed or carried into practical effect, we wish it to be understood
that we claim as our Invention, the improvements in the construction
of mules and turners as hercin-before described and shewn on the
Drawing annexed for effecting the running in of the carriage, con-
sisting mainly of a lever g, g, actuated by the spur wheels e, e, and ſ, ſ,
and carrying a wheel or bowl running in a curved slot, or between two
bars attached to the spindle carriage, substantially in the manner and
for the purposes herein-before set forth.
In witness whercof, I, the said Henry Baxter (on behalf of
myself and the said Luke Rushworth and Henry Clough), have
hereunto set my hand and scal, this Twenty-eighth day of
January, in the year of our Lord One thousand eight hundred
and seventy-six.
