IMPROVEMENTS IN MACHINERY FOR PREPARING AND COMBING WOOL OR OTHER FIEROUS SUBSTANCES
Year: 1869

page_text: TTERS PATENT to Peter Oldfield, of Bradford, in the County
of York, Manager of Combing Machinery, for the Invention of
"IMPROVEMENTS IN MACHINERY FOR PREPARING AND COMBING WOOL OR
OTHER FIEROUS SUBSTANCES."
Scaled the 16th July 1869, and dated the 18th January 1809.
PROVISIONAL SPECIFICATION left by the said Peter Oldfield at the
Office of the Commissioners of Patents, with his Petition, on
the 18th January 1869.
I, PETER OLDFIELD, of Bradford, in the County of York, Manager of
Combing Machinery, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY FOR PREPARING AND COMBING WOOL OR OTHER
FIBROUS SUBSTANCES," to be as follows:-
This Invention relates to the pairs of fluted drawing rollers employed
in such machinery, and my improvements consist in constructing the

page_text: flutes of such rollers in a spiral, skew, or twisted direction instead of
parallel to the axis as heretofore, the flutes of one roller being twisted
right and the other left so as to fit together in pairs.
By this Invention I obtain more equal action or pressure on the
wool or fibrous substance under operation, and also on the leathers 5
employed therewith, consequently effecting a more steady working with
a reduction of power required, and also great economy in wear and tear
of leathers.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Peter Oldfield in the Great Seal Patent Office on
the 17th July 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
OLDFIELD, of Bradford, in the County of York, Manager of Combing
Machinery, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 1
Letters Patent, bearing date the Eighteenth day of January, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Peter Oldfield, Her special
licence that I, the said Peter Oldfield, my executors, administrators, 2
and assigns, or such others as I, the said Peter Oldfield, my exe-
cutors, 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, 2
tbe Channel Islands, and Isle of Man, an Invention for "IMPROVE
MENTS IN MACHINERY FOR PREPARING AND COMBING WOOL OR OTHER FIBROUS
SUBSTANCES," upon the condition (amongst others) that I, the said Peter
Oldfield, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly 3
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to ba

page_text: 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 Peter Oldfield, 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 Sheet of Drawings (that is to
say) :-
This Invention relates to the pairs of fluted drawing-off rollers employed
in such machinery, and my improvements consist in constructing the
flutes of such rollers in a spiral, skew, or twisted direction instead of
parallel to the axis as heretofore, the flutes of one roller being twisted
right and the other left, or so as to fit together in pairs.. The spiral
skow or twist of the flutes may be made in one or moro revolutions or
circuits around the rollers as betwixt one end and the other thereof, or
they may be in less than one circuit, or only form part of a circuit;
also, instead of the said flutes continuing to run spirally in one
direction, they may run partly in one direction and partly in the other
in a curvilinear manner as in curve lines upon a cylindrical surface, as
shown by tho accompanying Sheet of Drawings, where Fig. 1 is the
longitudinal view, and Fig. 2 the end view of a pair of such rollers.
In the constructing of these rollers they may be done by ordinary
fluting machines by giving a partial rotary or oscillatory motion to the
roller when under operation of the flute-cutting tool, and it must be
understood that they must be made so as to fit together in pairs.
By this Invention I obtain more equal action or pressure on the wool
or other fibrous substances under operation, and also on the leathers
employed therewith, consequently effecting a more steady working, with
a reduction of the motive power required for driving, and great economy
in machinery, also proventing wear and tear of leathers.
Having thus fully described the nature of my said Invention, and the
manner in which the same is to bo or may be performed, I would have
it understood that I do not confine or restrict myself to the precise
details hercin set forth; but what I claim is, the construction, appli-
cation, and uso of drawing-off rollers with spiral, skew, twisted, or curved

page_text: flutes in machinery for preparing and combing wool or other fibrous
substances.
In witness whereof, I, the said Peter Oldfield, have hereunto set my
hand and seal, this Fifteenth day of July, in the year of our Lord
One thousand eight hundred and sixty-nine.
Signed, sealed, and delivered
by the within-named Peter
Oldfield, in the presence
of
W. TASKER,
Patent Agent,
Halifax & Bradford.
PETER OLDFIELD. (L.S.)
