Year: 1879

page_text: LETTERS PATENT to John Leigh Taylor, of Bolton, Cotton Spinner, and
Thomas Henry Rushton, of the samo Place, Machine Maker, for the Invention
of "IMPROVEMENTS IN TOP CLEARERS FOR THE DRAWING ROLLERS OF
PREPARING AND SPINNING MACHINERY."
Sealed the 11th June 1880, and dated the 20th December 1879.
PROVISIONAL SPECIFICATION left by the said John Leigh Taylor and
Thomas Henry Rushton at the Office of the Commissioners of Patents on the
20th December 1879.
JOHN LEIGH TAYLOR, of Bolton, Cotton Spinner, & THOMAS HENRY RUSHTON,
of same Place, Machino Maker. "IMPROVEMENTS IN TOP CLEARERS FOR THE
DRAWING ROLLERS OF PREPARING & SPINNING MACHINERY."
Our improvements in clearers for preparing & spinning machines consist in
making the clearer driven by gearing (preferably) at a slower surface speed than
the slowest roller on the machine, with the driving shaft coupled in such a manner
that any one box or length of clearer can be at once removed and instantaneously
replaced by an other.
The coupling may form part of the working neck, & be formed by a tongue on
the end of one length working into a recess on the end of the other, thus being
capable of being lifted out vertically when in a proper position.

the said John Leigh Taylor and Thomas Henry Rushton in the Great Seal
Patent Office on the 18th June 1880.
JOHN LEIGH TAYLOR, of Bolton, Cotton Spinner, and THOMAS HENRY RUSHTON,
of the same Place, Machine Maker. "IMPROVEMENTS IN TOP CLEARERS FOR THE
DRAWING ROLLERS OF PREPARING AND SPINNING MACHINERY."
Our improvements in clearers for preparing and spinning machines consist in
making the clearer driven by gearing (preferably) at a slower surface speed than
the slowest roller on the machine, with the driving shaft coupled in such a manner
that any one box or width of clearer can be at once removed and instantaneously
replaced by another. The coupling may form part of the working neck and be
formed by a tongue on the end of one length working into a recess in the end of
the other, thus being capable of being lifted out vertically when in a proper
position.
And in order that our Invention may be fully understood and readily carried
into effect we will describe the accompanying Sheet of Drawings, reference being
had to the Figures and letters marked thereon.
Fig. 1 is a cross section of part of a roving frame to which our Invention is
applied, and Fig. 2 is a plan of the same; a, a, are the top rollers; b is the clearer
driven by the shaft c at a slower surface speed than that of the slowest top roller;
this shaft is driven from any convenient part of the machine. The shaft is divided
into lengths, one for each box or width of clearer, and these lengths are coupled
together by a tongue c¹ on one length taking into a recess in the other length, so
that any length can be lifted out vertically when the shaft is in the position shewn
in Fig. 2.
Having stated the nature of our Invention and described a manner of performing
the same, we declare that we claim,―
Coupling the driving shaft of top clearers in such a manner as to allow any
length of clearer to be at once removed and instantaneously replaced, and the
method of effecting the same, substantially as shewn and described.
In witness whereof, I, the said Thomas Henry Rushton, for myself and on
behalf of the said John Leigh Taylor, have hereunto set my hand and seal
this Sixteenth day of June, One thousand eight hundred and eighty.
THOS. HENRY RUSHTON. (LS)
