IMPROVEMENTS IN ROVING FRAMES FOR MANIPULATING WOOL AND OTHER FIBROUS SUBSTANCES
Year: 1880

page_text: LETTERS PATENT to Thomas Ellison Smith, of the Firm of Smith and Sons,
Royd Works, Keighley, in the County of York, Machine Maker, for an
Invention of "IMPROVEMENTS IN ROVING FRAMES FOR MANIPULATING WOOL
AND OTHER FIBROUS SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Thomas Ellison Smith at
the Ottice of the Commissioners of Patents on the 27th September 1880.
THOMAS ELLISON SMITH, of the Firm of Smith and Sons, Royd Works, Keighley,
in the County of York, Machine Maker. "IMPROVEMENTS IN ROVING FRAMES
FOR MANIPULATING WOOL AND OTHER FIBROUS SUBSTANCES."
The object of this Invention is to arrange roving frames in such a manner that
the fibre which is being manipulated can be passed through the machine at a
quicker rate than is accomplished by the method now in cominon use.
I accomplish my object in the following manner:-
To the top spindle rail in roving frames I secure a series of stationary spindles.
On to each of these spindles is placed a rotating collar or tube; resting upon the
said collar or tube is the bobbin, which revolves at the same rate of speed. At the
top of each stationary spindle is placed a cap that projects downward and partly
covers the rotating bobbin, which rises and falls within the said cap for the purpose
of having the fibre built upon the same.

THOMAS ELLISON SMITH, of the Firm of Smith and Sons, Royd Works, Keighley,
in the County of York, Machine Maker. " IMPROVEMENTS IN ROVING FRAMES
FOR MANIPULATING WOOL AND OTHER FIBROUS SUBSTANCES."
The object of this Invention is to arrange roving frames in such manner that
the fibre which is being manipulated can be passed through the machine at a
quicker rate than is accomplished by the method now in common use.
I accomplish my object in the following manner :—
To the top spindle rail in roving frames I secure a series of stationary spindles,
at the top of which I fix a cap of a size suitable to that of the bobbin. On to
each of the spindles is placed a rotary tube, having a wharl at the bottom similar
to those used in cap spinning, and to which rotary notion is transmitted in the
ordinary manner. This wharl collar rests upon the lifter rail, which is regulated
by the lifter moving the said rail and contents thereon to and fro in a vertical
direction within the said cap, building the roving thread on to the roving bobbin,
as is the case with cap spinning. By the utilization of caps for roving frames,
I am enabled to run bobbins mounted on the tubes at about double the speed at
which fly spindles can be run, in consequence of the fly legs opening out from
the spindle when run at a high rate of speed; whereas by my arrangement the
tubes and bobbins thereon can be run at any increased speed suitable to the fibre
that is being manipulated, and in proportion to the increased speed at which the
tubes and bobbins are run above that of fly spindles, so will a corresponding
increase in the weight of fibre passing through the machine be obtained.
What I claim as my Invention is,
The utilization of caps for roving frames, substantially in the manner and for
the purpose herein set forth.
In witness whereof, I, the said Thomas Ellison Smith, have hereunto set
my hand and seal, this Twenty fourth day of March, in the year of our
Lord One thousand eight hundred and eighty-one.
