Year: 1863

page_text: LETTERS PATENT to Thomas Wimpenny, of Holmforth, in the County of
York, Manufacturer, for the Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR ROVING AND SPINNING WOOL, COTTON, AND
OTHER FIBROUS SUBSTANCES."
Sealed the 12th January 1864, and dated the 15th July 1863.
PROVISIONAL SPECIFICATION left by the said Thomas Wimpenny at the
Office of the Commissioners of Patents, with his Petition, on the 15th
July 1863.
I, THOMAS WIMPENNY, of Holmforth, in the County of York, Manufac-
turer, do hereby declare the nature of the said Invention for "CERTAIN IM-
PROVEMENTS IN MACHINERY OR APPARATUS FOR ROVING AND SPINNING WOOL, COTTON,
AND OTHER FIBROUS SUBSTANCES," and for which Letters Patent were granted to
me, dated April 18, 1855, No. 819.
The subject of such Patent related to the novel construction or arrange-
ment of machinery or apparatus for the purpose of simultaneously drawing and
spinning wool cardings (or wool mixed with other fibrous substances), and
consequently dispensing with the traversing spindle carriage at present in use
in "billies," "mules," and other apparatus or machinery employed in spinning
wool and worsted. The said improvement consisting in passing the carding
(immediately upon its leaving the delivering rollers) through a pair of fluted
rollers (revolving at the required speed) enclosed in a circular box or, case,
and which rollers are caused to revolve in an opposite direction to each other

page_text: by means of a small pinion connected with, and attached to one of the fluted
rollers inside the circular box by means of a worm and worm wheel. The
present improvements consist, first, in the use of two circular boxes, one re-
volving upon the other, and having their peripheries toothed (like pinions), so
as to gear with other pairs of boxes from end to end of the machine, one of
such boxes carries the internal rollers and the driving gearing, which is con-
structed with bevil gearing instead of worm and worm wheels, and the other is
provided with an internal pinion gearing with the small pinion driving the bevil
gearing. These boxes are so placed from end to end of a frame, that one
pair drives the next pair, and so on, the whole being driven by a pair of spur
change wheels at the end of the frame, thus, the relative speeds of the two
boxes may be altered so as to regulate the twist and "draught" to be
given to the sliver, which was impracticable when only one box driven by a
baud was employed as in the before-mentioned Letters Patent.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Wimpenny in the Great Seal Patent Office on the
15th January 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WIMPENNY, of Holmforth, in the County of York, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of July, in the year of our Lord One
thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Wimpenny, Her special license that I, the said Thomas
Wimpenny, my executors, administrators, and assigns, or such others as I, the
said Thomas Wimpenny, my 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
"CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR ROVING AND SPINNING
WOOL, COTTON, AND OTHER FIBROUS SUBSTANCES," upon the condition (amongst
others) that I, the said Thomas Wimpenny, my executors or administrators,
by an instrument in writing under my, or their, or one of their bands and seals,
should particularly describe and ascertain the nature of the said Invention,

page_text: 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 I, the said Thomas Wimpenny, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, and accompanying Drawings (that is to say) :-
My Invention relates to certain improvements upon apparatus for roving
and spinning wool, cotton, and other fibrous substances, for which Letters
Patent were granted to me, bearing date the Thirteenth day of April, One
thousand eight hundred and fifty-five, the subject of such Patent relating to
the novel construction or arrangement of machinery or apparatus for the pur-
pose of simultaneously drawing and spinning wool cardings (or wool mixed
with other fibrous substances), and consequently dispensing with the tra-
versing spindle carriage at present in use in "billies," "mules," &c., employed
in spinning wool and worsted. The said improvement consisting in passing
the carding (immediately upon its leaving the delivery rollers) through a pair
of fluted rollers (revolving at the required speed) enclosed in a circular box
or case, and which rollers are caused to revolve in an opposite direction to
each other by means of a small pinion connected with, and attached to one of
the fluted rollers inside the circular box by means of a worm and worm wheel.
The present improvements consist, first, in the use of two circular boxes, one
revolving upon the other, and having their peripheries toothed (like pinions)
so as to gear with the other pairs of boxes from end to end of the machine,
one of such boxes carries the internal rollers and the driving gearing, which
is constructed with bevil gearing (instead of worm and worm wheel), and tho
other is provided with an internal pinion gearing, with the small pinion driving
the bevil gearing. These boxes are so placed from end to end of a frame,
that one pair drives the next pair, and so on, the whole being driven by a
pair of spur change wheels at the end of the frame, thus the relative speeds
of the two boxes may be altered so as to regulate the twist and and draught
to be given to the sliver, which was impracticable when only one box driving
by a band was employed as in the before-mentioned Letters Patent.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings made about full size.
Fig. 1 is a plan view, exhibiting the driving arrangement of the boxes in
which the top plate covering the boxes is removed to shew the interior con-
struction thereof; Fig. 2 is a vertical section of the same. In Figs. 1 and 2,
a, a', are the pairs of circular boxes which revolve-upon each other, and are

page_text: toothed at their peripheries like pinions, so as to gear into and drive the next
set as shewn. Within one of these box wheels the internal rollers b, b, are
mounted, between which the "sliver" passes, and the pressure of which is
regulated by a spring c. These rollers are driven from a pinion d in the other
box, which gears with a pinion e on a short shaft, at the other end of which is
a bevil wheel gearing into a bevil wheel 9 on the roller shaft, which through
the spur wheels h, h, drives both rollers. The boxes being toothed and placed
in diagonal positions, enables one set to be driven by the other from end to
end of the machine, the first set being driven by ordinary change wheels at
one end of the machine. By this means a positive motion is given to the
rollers, and the relative speeds of the boxes and rollers may be regulated and
governed so as to regulate the twist to be given to the "sliver." I would also
remark that the boxes may be grooved at the periphery, and so placed as to
be driven by an endless band.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim,-
First, the novel construction and adaptation of the loose box marked a',
revolving on the tubular axis of the box containing the draught rollers, also, the
arrangement of driving such boxes geared together in continuous succession,
whereby a positive motion is obtained, and their speeds governed and regulated
to cause any draught required.
Secondly, the novel construction and arrangement of the several parts
as herein-before described, set forth, and fully illustrated in the Drawings
attached.
In witness whereof, I, the said Thomas Wimpenny, have hereunto set
my hand and seal, this Fourteenth day of January One thousand eight
hundred and sixty-four.
THOMAS WIMPENNY. (L.s.)
