IMPROVE- MENTS IN CARDING ENGINES
Year: 1880

page_text: LETTERS PATENT to Spencer Henry Bickham, junior, and William Houldsworth,
both of Pendleton, in the County of Lancaster, for an Invention of "IMPROVE-
MENTS IN CARDING ENGINES."
PROVISIONAL SPECIFICATION left by the said Spencer Henry Bickham,
junior, and William Houldsworth at the Office of the Commissioners of Patents
on the 21st January 1880.
SPENCER HENRY BICKHAM, junior, and WILLIAM HOULDSWORTH, both of
Pendleton, in the County of Lancaster. "IMPROVEMENTS IN CARDING ENGINES."
This Invention relates to an entirely new construction of stripping roller, the
object of which is to thoroughly strip and clean the cards of the main cylinders
and doffers of carding engines whilst they are working.
This said Invention consists of a combination of two rollers, viz., a stripping
roller proper and a carrier roller, so arranged (the one partly inside the other) as
to form together one compound roller possessing several advantages over any roller
hitherto used for the purpose.
The stripping roller proper (of which there may be more than one) is covered
either partly or completely with card clothing suitable for stripping and cleaning
cards, either set with teeth of tempered steel or otherwise, or with pins set in
leather or woollen cloth or any other suitable material.
The said stripping roller (the centre of which is fixed at such a point between
the centre and circumference of the carrier roller that the teeth of the stripper are
made to stand above the periphery of the said carrier roller) is made to revolve
any desired speed round its own axis, and whilst so revolving the carrier roller is
also made to revolve round its own centre and carry the stripping roller with it,
after the manner of a sun and planet motion, thus giving to the periphery of the
stripping roller a motion compounded of these two revolving motions, thereby
attaining a very great surface velocity at that point only where the teeth of the
stripping roller stand above the periphery of the carrier, whilst the carrier and
stripper are cach revolving at a comparatively slow speed.

SPENCER HENRY BICKHAM, junior, and WILLIAM HOULDSWORTH, both of
Pendleton, in the County of Lancaster. IMPROVEMENTS IN CARDING ENGINES."
This Invention relates to an entirely new construction of stripping roller, the
object of which is to thoroughly strip and clean the cards of the main cylinders
and doffers of carding engines whilst they are working.
This said Invention consists of a combination of two rollers, viz., a stripping
roller proper and a carrier roller, so arranged (the one partly inside the other) as
to form together one compound roller possessing several advantages over any roller
hitherto used for the purpose.
The stripping roller proper (of which there may be more than one) is covered
either partly or completely with card clothing suitable for stripping and cleaning
cards, either set with teeth of tempered steel or otherwise, or with pins set in
leather or woollen cloth, or any other suitable material.
The said stripping roller (the centre of which is fixed at such a point between
the centre and circumference of the carrier roller that the teeth of the stripper are
made to stand above the periphery of the said carrier roller) is made to revolve at
any desired speed round its own axis, and whilst so revolving the carrier roller is
also made to revolve round its own centre and carry the stripping roller with it,
after the manner of a sun and planet motion, thus giving to the periphery of the
stripping roller a motion compounded of these two revolving motions, thereby
attaining a very great surface velocity at that point only where the teeth of the
stripping roller stand above the periphery of the carrier, whilst the carrier and
stripper are each revolving at a comparatively slow speed, the advantage of which
is that we are enabled to obtain a perfect stripping action with very much less
wind or air current than heretofore, and hence the fleece is much less liable to
become disturbed and blown about, and the sliver is much more
regular.
even and
The accompanying Drawings illustrate fully the nature of the said Invention
and the manner in which the same is to be performed or carried into practical
effect.
Fig. 1 is a side clevation of so much of a carding engine as is necessary to
illustrate the application of our Invention.
Fig. 2 is an end view of the two rollers, which together form the compound
stripping roller; and Fig. 3 is a similar view showing the method of driving the
stripping roller. a, a, is the stripping roller proper, and b, b, is the carrier
roller.
The stripping roller a, a, is covered as before said with teeth of a suitable
character for stripping cards, the points of which are made to stand above the
circumference of the carrier roller b, b, as shown, between the points c, d, so as to
work into or among the card teeth of the main cylinder e*, e*, or any other part or
roller to be stripped or cleaned.
This said roller a, a, is made to revolve round its own centre e in the direction
of the arrows, and whilst so revolving its said centre e is carried round by the
revolution of the carrier roller b, b, which is also made to revolve round its own
centre in the direction of the dotted arrows, thus giving to that part of the
periphery of the roller a which lies between c and d a motion compounded of the
two revolving movements of the rollers a, a, and b, b, thereby acquiring a very
great surface velocity at that point only (viz., between c and d), whilst each of
the rollers a and b is revolving at a comparatively slow speed.
The accelerated movement of the roller a, a, is produced by the toothed pinion

page_text: g, g, on the end of its axis rolling round and in gear with a spur wheel h, h, which
is fixed to the bearing of the roller, so as to remain immovable. The carrier roller
b, b, is driven in the usual manner.
Having now described the nature and object of our said Invention, together
with the manner in which the same is to be or may be performed or carried into
practical effect, we wish it to be understood that we claim as our Invention, the
construction and use of the compound stripping roller, substantially in the manner
and for the purposes hereinbefore particularly set forth and described.
In witness whereof, I, the said William Houldsworth (on behalf of myself
and the said Spencer Henry Bickham, junior), have hereunto set my hand
and seal, this Nineteenth day of July, in the year of our Lord One
thousand eight hundred and eighty.
WILLIAM HOULDSWORTH. (L.S.)
