Sealed the 21st June 1853, and dated the 24th March 1853.
(Void by reason of the Patentees having neglected to file a Specification
in pursuance of the conditions of the Letters Patent.)
PROVISIONAL SPECIFICATION left by the said Robert Grundy
and James Jones at the Office of the Commissioners of Patents,
with their Petition, on the 24th March 1853.
1, ROBERT GRUNDY, of Hindley, in the County of Lancaster, &
JAMES JONES, of Warrington, in the same County, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
POR PREPARING, SPINNING, AND DOUBLING COTTON AND OTHER FIBROUS
MATERIALS" to be as follows:-

page_text: Our Improvements consist in certain new machinery to be used in
place of the slubbing, roving, spinning, and doubling machines now
employed. In making slubbings we propose to take the cans from an
ordinary drawing frame, and to place each can in an open revolving
frame; this frame is somewhat like a flyer, but it must be large enough
to contain the can from the drawing frame and a set of drawing rollers,
which are placed above the can and supported in bearings attached to
the revolving frame; the revolving frame is supported above in a top
rail, and below in a foot step, and motion is given to it by a skew wheel
fixed on the revolving frame, and another skew wheel fixed on a hori-
zontal shaft. The drawing rollers are made to rotate on their own
axes by two bevel wheels fixed in a double beam extending from end
to end of the machine; the lowest drawing roller has a worm fixed to
one end gearing into a worm wheel fixed on a short upright shaft, to
the lower end of which is a bevel pinion gearing into the stationary
bevel wheel fixed in the beam; consequently, when the revolving frame
turns round, the bevel and worm wheels cause the bottom drawing
roller to revolve. The top drawing roller is turned round in the same
manner, but at a greater velocity, from the upper bevel wheel fixed to
the beam; and the intermediate drawing roller is driven from the
bottom one in the ordinary manner. The slubbing thus produced is
carried through an eye in the top bearing of the revolving frame, and
wound on to a bobbin, which when full is taken to our improved
machine, to be used in place of the ordinary roving frame; this machine
is similar to the one above described, but it may be of smaller dimen-
sions. The rovings produced on our improved roving frame are wound
on to bubbins which are placed in the revolving frames of our improved
spinning machine, which is also similar to the stubbing frame herein-
before described. The yarn made on our improved spinning frame can
be wound on to pin cops ready for the shuttles of looms, or on to a reel
in the form of hanks, or on bobbins of any convenient size or shape.
When our improved machine is used for doubling it is evident that two
bobbins of yarn must be supported in the revolving frame; and we wish
to remark that the principal advantage of our improved machinery

page_text: consists in causing the slivers, slubbings, rovings, or yarns, with which
the machines are fed, to revolve with the drawing rollers, thereby
avoiding twist at the feeding end, and putting twist into the delivering
end of the cotton or other fibrous material under operation.
