page_text: LETTERS PATENT to Thomas Craig, of Bradford, in the County of York, Wool
Comber, for the Invention of "IMPROVEMENTS IN MACHINERY FOR CARDING
FIBRES."
PROVISIONAL SPECIFICATION left by the said Thomas Craig at the Office
of the Commissioners of Patents on the 8th February 1878.
THOMAS CRAIG, of Bradford, in the County of York, Wool Comber.
MENTS IN MACHINERY FOR CARDING FIBRES."
"
"IMPROVE-
This Invention relates to a new and improved arrangement of fancy roller,
cylinder," or "swift" and "doffer," whereby the fibre may be raised on the
cylinder or swift as ordinary, and the said cylinder or swift, as also the doffer, may
at the same time be cleaned without stopping the machine or re-adjusting the rollers
or cylinders.
I employ a fancy roller having at the outer edges or lines of the card, strips, or
fillets hardened and tempered steel teeth, the other teeth or cards with which such
roller is covered or clothed are of ordinary wire, the steel teeth referred to being
however somewhat longer than the other cards or teeth.
The fancy I mount (upon adjustable bearings) within the angle of the cylinder
and the doffer, so as to be in gear or in work with both the cylinder and the doffer;
the long teeth of hardened and tempered steel performing the office of cleaning both
the cylinder and the doffer, the ordinary cards performing their ordinary office upon
the fibre

This Invention relates to a new and improved arrangement of fancy roller,
'cylinder," or "swift" and "doffer," whereby the fibre may be raised on the
cylinder or swift as ordinary, and the said cylinder or swift, as also the doffer, may
at the same time be cleaned without stopping the machine or re-adjusting the rollers
or cylinders.
I employ a fancy roller having at the outer edges or lines of the card, strips, or
fillets hardened and tempered steel teeth, the other teeth or cards with which such
roller is covered or clothed are of ordinary wire, the steel teeth referred to being
however somewhat longer than the other cards or teeth.
The fancy I mount (upon adjustable bearings) within the angle of the cylinder
and the doffer, so as to be in gear or in work with both the cylinder and the doffer.
The long teeth of hardened and tempered steel perform the office of cleaning both the
cylinder and the doffer, the ordinary cards performing their ordinary office upon the.
fibre.
The following is a full and complete description of the Invention illustrated by
Drawings, of which,―
Fig. 1 is an elevation shewing means of adjustment of the fancy roller.
.
Fig. 2 is a section shewing the relative position of the fancy, the doffer, and the
cylinder.
I employ a fancy roller having at the outer edges or lines of the cards, strips, or
fillets hardened and tempered steel teeth, the other teeth or cards with which such
roller is covered or clothed are of ordinary wire, the steel teeth referred to being
however somewhat longer than the other cards or teeth.
The fancy roller A I mount (upon adjustable bearings B) within the angle of the
cylinder Cand the doffer D so as to be in gear or in work with both the said cylinder
and doffer. The longer teeth E of the fancy are made of hardened and tempered
steel and perform the office of cleaning both the said cylinder C and the doffer 1),
the ordinary cards F performing their ordinary office upon the fibre.
Having thus fully described the nature and particulars of this my said Invention,
'I would have it understood that I lay no claim separately to the use of the hardened
and tempered longer teeth E, but what I do claim is the use of the fancy roller A,
adjustable and working in connection and contact with the cylinder C and doffer D,
as illustrated, and for purposes described.
In witness whereof, I, the said Thomas Craig, have hereunto set my hand and
seal, this Fifth day of August, in the year of our Lord One thousand eight
hundred and seventy-eight
