IMPROVE- MENTS IN CONDENSER CARDING ENGINES
Year: 1868

page_text: LETTERS PATENT to William Richardson, of Oldham, in the County
of Lancaster, Mechanical Engineer, for the Invention of "IMPROVE-
MENTS IN CONDENSER CARDING ENGINES."
Sealed the 11th May 1869, and dated the 14th November 1868.
PROVISIONAL SPECIFICATION left, by the said William Richardson at
the Office of the Commissioners of Patents, with his Petition, on
the 14th November 1868.
I, WILLIAM RICHARDSON, of Oldham, in the County of Lancaster,
Mechanical Engineer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN CONDENSER CARDING ENGINES," to be as follows:-
My Invention relates to the apparatus which is used for removing the
material from the rings of cards and for separating them into distinct
slivers, whereby I am enabled to employ a cylinder with comparatively
narrow spaces between the said rings of cards. For this purpose I
dispense with the usual card or other such roller used for doffing, and
apply a reciprocating comb in conjunction with a roller grooved at right

page_text: angles to its axis. The aforesaid comb removes the material and delivers
it to the grooved roller, which then detaches it into separate slivers.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Richardson in the Great Seal Patent Office
on the 14th May 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
RICHARDSON, of Oldham, in the County of Lancaster, Mechanical
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of November, in the year
of our Lord One thousand eight hundred and sixty-nine, and in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Richardson, Her special licence that
I, the said William Richardson, my executors, administrators, and assigns,
or such others as I, the said William Richardson, my executors, adminis-
trators, 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 "IMPROVEMENTS IN CONDENSING CARDING
ENGINES," upon the condition, amongst others, that I, the said William
Richardson, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said
Invention, 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 William Richardson, do hereby declare
the nature of my 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 the apparatus which is used for removing the
material from the rings of cards and for separating them into distinct

page_text: slivers. For this purpose I dispense with the usual card or other such
roller used for doffing, and apply a reciprocating comb in conjunction
with a roller grooved at right angles to its axis. The aforesaid comb
removes the material and delivers it to the grooved roller, which then
retains it in separate slivers.
In the accompanying Drawing Fig. 1 shews so much of a condensing
carding engine as is sufficient to explain my Invention, and Fig. 2 is a
section of a portion of the grooved roller for keeping the slivers separate,
and which in itself is in well-known use.
At a is the doffer cylinder provided as usual with rings of cards, and
behind which are the two rollers b, which carry the bottom travelling
belt c. At d are the rollers which carry the upper belt e, and to each of
them the usual transverse reciprocating motion is imparted for the
condensation of the slivers. In front of the upper belt is the grooved
roller f, constructed as shewn at Fig. 2, or in a similar manner. At g is
a doffer comb to which a vibratory motion is imparted by any ordinary
convenient means, so as to cause it to act against the wire of the doffer
cylinder a, and strip the slivers of material from the rings of cards.
These slivers then pass, as shewn by the Drawing, between the spaces h
of the roller f, where they are kept distinct, and from thence between
the belts c, e, to the bobbins i, k, which are driven as usual by the
surface drums l.
Having thus described and ascertained the nature of my said Invention,
and the manner in which it is to be performed, I desire it to be under-
stood that I do not claim any of the parts above described separately,
but I do claim as my Invention the combined use of a doffing comb
and grooved roller, as illustrated at g, f.
In witness whereof, I, the said William Richardson, have hereunto
set my hand and seal, this Thirteenth day of May, in the year of
our Lord One thousand eight hundred and sixty-nine.
WILLIAM RICHARDSON.
