CERTAIN IMPROVEMENTS IN APPARATUS FOR SPINNING AND TWISTING COTTON AND OTHER FIBROUS MATERIALS
Year: 1867

page_text: LETTERS PATENT to Henry Barton and Edward Whalley, of Blackburn,
in the County of Lancaster, for the Invention of "CERTAIN IMPROVEMENTS
IN APPARATUS FOR SPINNING AND TWISTING COTTON AND OTHER FIBROUS
MATERIALS."
Sealed the 3rd September 1867, and dated the 6th March 1867.
PROVISIONAL SPECIFICATION left by the said Henry Barton and Edward
Whalley at the Office of the Commissioners of Patents, with their
Petition, on the 6th March 1867.
We, HENRY BARTON and EDWARD WHALLEY, of Blackburn, in the County
of Lancaster, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN APPARATUS FOR SPINNING AND TWISTING COTTON AND
OTHER FIBROUS MATERIALS," to be as follows:-
The Invention relates to the apparatus employed in spinning termed "self-
acting mules," and is designed to dispense with the "rim band" and pulleys,
and to effect a positive driving motion for the "tin drum" or spindle driving
shaft, and at the same time to cause such positive motion to yield slightly
when "backing off."
The improvements consist in the employment and use of a driving toothed
wheel revolving loosely on the driving shaft, which is driven by means of an
arm secured on the said shaft through the medium of a coiled spring, which is

page_text: attached to the wheel by means of a rod extending round its circumference,
around which rod the spring is coiled, the end of the arm being curved or
forked so as to clip the rod; thus the toothed wheel cannot receive motion
until the spring is acted upon by the arm either by compression or extension,
so that when driving power is suddenly applied to the wheel the spring effects
the necessary yield and allows the "backing off" and revolution of spindles to
"wind on" to be effected without injuring the teeth of the driving wheel or
other gearing. This motion may be transferred to the "tin drum" shaft by
toothed wheel or other equivalent gearing which is arranged to drive the said
shaft, on which a skewed bevil wheel slides to and fro according to the
motion of the spindle carriage, which gears with another bevil driving the
"tin drum" which drives the spindles.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Barton and Edward Whalley in the Great Seal Patent
Office on the 6th September 1867:
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
BARTON, and EDWARD WHALLEY, of Blackburn, in the County of Lancaster,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of March, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Henry Barton and Edward Whalley, Her special license that we, the
said Henry Barton and Edward Whalley, our executors, administrators,
and assigns, or such others as we, the said Henry Barton and Edward
Whalley, our exécutors, 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 APPA-
RATUS FOR SPINNING AND TWISTING COTTON AND OTHER FIBROUS MATERIALS," upon
the condition (amongst others) that we, the said Henry Barton and Edward
Whalley, our executors 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

page_text: "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 Barton, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):
--
The Invention relates to the apparatus employed in spinning termed self-
acting mulės, and is designed to dispense with the "rim band" and pulleys,
and to effect a positive driving motion for the "tin drum" or spindle driving
shaft, and at the same time to cause such positive motion to yield slightly
when "breaking off." The improvements consist in the employment and use
of a driving toothed wheel and disc revolving loosely on the driving shaft,
which wheel is driven by means of an arm or arms secured on the said shaft
through the medium of a coiled spring, which is attached to the wheel by
means of a rod extending round its circumference, around which rod the spring
is coiled; or the rod may be dispensed with, the end of the arm being curved
or forked so as to clip the rod; thus the toothed wheel cannot receive motion
until the spring is acted upon by the arm either by compression or extension,
so that when driving power is suddenly applied to the wheel the spring effects
the necessary yield and allows the "backing off" and revolution of spindles to
"wind on" to be effected without injuring the teeth of the driving wheel or
other gearing. This motion may be transferred to the "tin drum" shaft by
toothed wheel or other equivalent gearing, which is arranged to drive an
intermediate shaft on which a squewed bevil wheel slides to and fro according
to the motion of the spindle carriage, which gears with another bevil or bevils
driving the tin drum which drives the spindles.
In order that the Invention may be better understood and explained in
detail we have hereunto attached a Sheet of Drawings illustrative of same.
Fig. represents an enlarged side elevation shewn in section of the
improved apparatus employed to drive the "tin drum or spindle shaft instead
of the ordinary rim wheel and band.
"
Fig. 2 is a front or face view of the disc or plate in which the coiled springs
are sunk in a groove, which springs are secured at one end to the plate, and
at the other to each of the arms; in this view the shield or cover is
removed.
Fig. 3 represents a portion of a "mule headstock" illustrating the appli-
cation of the positive gearing and the yielding springs thereto.
In Fig. 1 a, a, is the main driving shaft of the "mule headstock" upon
which the arms b, b, are secured, which are attached to one end of the single

page_text: or double coiled spring c, c, the other ends of the springs being attached to
the plate (as seen in Fig. 2.), and by means of the arms 6, 6, the grooved
plated and the spur pinion e attached thereto are caused to rotate and to
communicate motion to the spur wheel f, which is transferred through the
apparatus shewn in Fig. 3 to the "tin drum" for driving the spindles, such
apparatus between the spur wheel and "tin dram" not being new. It will
thus be evident that when driving power is suddenly applied to the pinion and
spur wheel the spring effects the necessary yield, and allows the "backing
off" and revolution of the spindles and winding on to be effected without
stripping the teeth of the driving wheel or other gearing.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, we wish it to be distinctly
understood that we claim the novel arrangement and application of a coiled
spring or springs, and the combined mechanism to be employed between the
driving shaft of the mule headstock and spindle driving drum, whereby a
yielding action is imparted to the positive driving spur wheel gearing, and the
sudden action and consequent stripping of the teeth is prevented as herein.
before described, set forth, and fully illustrated in the Drawings attached.
In witness whereof, I, the said Henry Barton, have hereunto set my
hand and seal, this Fourth day of September, in the year of our Lord
One thousand eight hundred and sixty-seven.
