IMPROVEMENTS IN MULES FOR SPINNING
Year: 1864

page_text: LETTERS PATENT to John Paley, of Preston, Cotton Spinner, and Thomas
Rawsthorne, of Preston, Manager, both in the County of Lancaster, for
the Invention of "IMPROVEMENTS IN MULES FOR SPINNING
Sealed the 2nd May 1865, and dated the 23rd November 1864.
PROVISIONAL SPECIFICATION left by the said John Paley and Thomas
Rawsthorne at the Office of the Commissioners of Patents, with their
Petition, on the 23rd November 1864.
We, JOHN PALEY, of Preston, Cotton Spinner, and THOMAS RAWSTHORNE,
of Preston, Manager, both in the County of Lancaster, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MULES FOR SPINNING," to
be as follows:-
These improvements consist in a method of driving the ordinary cam shaft
attached to self-acting mules in such a manner that a greater certainty of
action is attained, and whereby the liability to accident or breakage is pre-
vented or considerably lessened.
Instead of driving the cam shaft by means of the system now ordinarily
employed we propose to drive the ordinary cam shaft (or a countershaft to
drive the same) by means of a small endless strap or band. For this purpose
we place upon the cam shaft (or upon the countershaft) a fast and loose
pulley or a fast pulley alone, on which runs an endless strap or band driven
from another pulley placed on any convenient shaft, which causes the cam
shaft to revolve at intervals when required, such intervals being determined
by means of the arrangement of mechanism now ordinarily employed for such
purpose or by any other similar or suitable arrangement.

by the said John Paley and Thomas Rawsthorne in the Great Seal
Patent Office on the 9th May 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
PALEY, and THOMAS, RAWSTHORNE, of Preston, in the County of Lancaster,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of November, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-seventh
year of Her reign, did, for Herself, ler heirs and successors, give and
grant unto us, the said John Paley and Thomas Rawsthorne, Her special
licence that we, the said John Paley and Thomas Rawsthorne, our executors,
administrators, and assigns, or such others as we, the said John Paley and
Thomas Rawsthorne, 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 "Iм-
PROVEMENTS IN MULES FOR SPINNING," upon the condition (amongst others)
that we, the said John Paley and Thomas Rawsthorne, our. executors
or administrators, by an instrument in writing under 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 we, the said John Paley and Thomas Rawsthorne,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the accompanying
Drawings and to the letters and figures marked thereon, that is to say:-
Our Invention relates to the so arranging mechanism as to produce a
seperate and distinct motion to the cam shaft of self-acting spinning mules,
whereby a certainty of action is obtained and consequent prevention of
breakage.
These improvements are mainly carried into practical effect by substituting
for the "presant friction pullies (which frequently fail in action) a fast-and-
loose pully on the cam shaft, or a countershaft in any conveinient position, and

page_text: geared into cam shaft by wheels (for convenience of speeds). On to this pair
of pullies we work a small band from the overhead or any convenient shaft, on
which we fix a small pully for the purpose of driving. This band is moved
from fast to loose pully and vice versa, by a cam lever or other motion as con-
venience may dictate, which action shall or may be obtained from the screw
end of the main shaft of mule.
And in order that these esential features together with the other minor
details of our improvments may be properly understood, we shall now proceed
to describe the several Figures on the Drawings hereunto attached.
Fig. 1 is a side elevation of our arrangement as herein-before mentioned,
shewing overhead motion in connection with our arrangement with the
ordinary driving motion; Fig. 2 is a cross elevation at A, B, shewing the
same, and one mode of driving the cam shaft. In the different views similar
parts are marked with coresponding letters of reference.
a, in Figs. 1 & 2, is the driving shaft from which we propose geting our
motion through, and by band 6 from pully c to fast-and-loose pully d on the
side, and in connection with fast pully is a small wheel e geared into a larger
wheelf, the sizes of which will be regulated or determined by the required
speed; the larger wheelf is fixed on the cam shaft g, hence the motion.
The band 6 is removed from fast to loose pully, and vice versa by the fork
lever h, connected to the slideing bar i, which is held back by the spiral
spring j. At the other end of this sliding bar i is a pivot pin k, which is acted
upon by the cam 1; m is a cam that gives the alternate motion to the sliding
bar i by lifting the catch n, thereby liberating the sliding bar pivot, which bar
is drawn back by the spring j drawing the band on to the fast pully; the other
cam forces the sliding bar i back by and through the pivot pin k untill the
catch n falls down and holds it untill the cam 7 comes round again. These
cams are worked by a small countershaft o through and by the wheels p and q
from the ordinary screw at end of the mule driven shaft r.
We do not confine ourselves to this particular motion for removing the
band as we can and may effect the same object by a lever and cam acted upon
directly from the countershaft without the sliding bar or catch lever.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried
into effect, we may observe in conclusion that we do not confine ourselves
to the precise details or arrangements which we have had occasion to describe
or refer to, as many variations may be made therefrom without deviating from
the principals or main features of our Invention; but what we consider
novel and original, we therefore claim as herein-before is,―

page_text: First, a seperate and distinct band motion for driving the cam shaft.
Second, a self-acting motion from the screw end of the driven shaft of
mule, for removing the band from fast to loose pully, and vice versa, which
combined, will effect a great saving of wear and breakage, besides being
allmost noiseless in action, and also being enabled to make the changes of cam 5
shaft at any required speed very conveniently.
In witness whereof, we, the said John Paley and Thomas Rawsthorne,
have hereunto set our hands and seals, this Ninth day of May, One
thousand eight hundred and sixty-five.
JOHN PALEY.
