IMPROVEMENTS IN SCRIBBLING AND CARDING MACHINERY
Year: 1878

page_text: LETTERS PATENT to Joseph Hall, of Morley, near Leeds, in the County of
York, for the Invention of "IMPROVEMENTS IN SCRIBBLING AND CARDING
MACHINERY."
Sealed the 28th December 1878, and dated the 29th June 1878.
PROVISIONAL SPECIFICATION left by the said Joseph Hall at the Office of
the Commissioners of Patents on the 29th June 1878.
JOSEPH HALL, of Morley, near Leeds, in the County of York. "IMPROVEMENTS
IN SCRIBBLING AND CARDING MACHINERY."
This Invention consists in the employment of a cleaning roller placed in the
angle between the doffer cylinder and the swift on the lower side thereof. The
teeth of this roller may be either of ordinary wire, and either straight or bent in
the tooth, or they may be of tempered steel wire.
The roller may be in stationary bearings or in hinged brackets, so arranged that
where more than one cleaning roller is required they may be connected together
and thrown in and out of contact with the doffers or swifts, as required.
The rollers may be driven either from the "fancy" or swift by either gear wheels,
band, or strap.
If necessary, a plate may be fixed on the stripper to clear it while it is going.

Patent Office on the 9th January 1879.

"IMPROVEMENTS
This Invention consists in the employment of a cleaning roller placed in the
angle between the doffer cylinder and the swift on the lower side thereof. The
teeth of this roller may be either of ordinary wire or tempered steel wire, and they
may also be either straight or bent in the tooth; or strips of steel, wire cards, steel
plates, grooved rollers, or rollers covered with gutta percha, bristles, or other material
which will act as a brush to remove the dirt.
The rollers may be in stationary or moveable bearings, so arranged that where
more than one cleaning roller is required they may be connected together and
thrown in and out of contact with the doffers or swifts, as required.
The rollers may be driven either from the "fancy" or swift by gear wheels, band,
or strap, or may be driven from other sources.
In order that my Invention may be more fully understood I have hereunto
annexed a Sheet of Drawings illustrative thereof.
Fig. 1 represents a sectional elevation of such parts of a carding and scribbling
machine as are necessary for the purpose.
Fig. 2 is full olevation of Fig. 1.
A are my cleaning rollers, which are applied in the lower angles between the
swifts and doffers. These rollers are mounted in bearings B attached to the slide
bar C, which is free to move in the brackets D. About the centre of the bar C is a
rack E which gears with a toothed pinion F mounted on a stud fixed to the frame-
work, and capable of being turned by hand wheel G, by doing which the cleaning
rollers may be placed in contact with either the cylinders or "swift" and doffers, or
may be placed clear of both.
For driving the cleaning rollers I employ a cord passing round two pullies H,
and also round small pullies J on the roller shafts, motion being communicated to
one of the pulleys H from any convenient source.
Instead of mounting the rollers in slidable bearings, hinged or hanging bearings
may be employed, the rollers being connected and driven in a somewhat similar
manner to that herein shown.
Having thus described the nature of my Invention, and the manner in which
the same is to performed, I would have it understood that I claim, the application
of cleaning rollers to carding and scribbling machinery for all fibrous substances, in
manner and for the purpose substantially as herein shewn and described.
In witness whereof, I, the said Joseph Hall, of Morley, have hereunto set my
band and scal, this Nineteenth day of December, in the year of our Lord One
thousand eight hundred and seventy-eight.
