Improvements in Cleaning Drawing Rollers of Selfacting or Hand
Mules whilst in Motion.
We GEORGE HUDSON Manufacturer and JAMES THOMAS DAWSON, Spinner both
of Adwalton nr. Bradford Yorkshire do. hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Underneath the bottom Rollers of the Drawing Rollers we have a Scraper made
of sheet Steel or other Metals so arranged that same scrapes, the Grease or Accumu--
lation off the Roller. whilst in Motion, the Scraper is held in position by Holders
fixed on a Shaft that runs parallel with the Drawing rollers and has a Spring or
Weight so arranged as to keep the Scraper close to the Drawing rollers at more
or less pressure as required, the Shaft that holds the Scraper is also arranged that
same moves to right and left in an Oscillating kind of Motion given by. a Grooved
Cam fixed to the Surface roller Shaft connected by a Stud, the Cam being grooved.
& so constructed to give one or more Motion in its revolution.
On the Top Drawing Rollers we make a Scraper of Steel or other Metals. and
same is fixed on the Wood Guide Bar at the. Back of the Drawing rollers and
has a Natural Spring tendency in its Construction so as to press on the rollers.
as required, on the Scraper end we have bent the Steel up to allow the Grease
or Accumulations to drop into and slide out off the ends and thereby preventing
saine from falling on the fibre that is passing between the Rollers.
In Order that our Invention may be more completely understood we annex and
proceed to describe the accompanying Sheets of Drawings.

On the Surface roller shaft we have a Cam fitted, when same revolves gives the
Shaft c that holds the Scraper.an-Oscillating-Motion-by-being connected with stud e
that is fast on Shaft e at one end and moves in the Grove of the Cam at the
other end, Spring d is fixed on side of frame at one end and made adjustable so
as to give same more or less pressure as required at the other is fitted on the
Holder so as to press the Scraper to the Rollers, Lever is fitted on same shaft
that holds the Scraper and is for the purpose of lifting. the Scraper off the rollers
when required.

page_text: Having now particularly described and ascertained the Nature of our Invention
and in what manner the same is to be performed we declare that what we claim is
A Scraper made of Steel or other Metals fitted on a Shaft by Holders and
pressed to the Bottom Drawing rollers by means of Spring or Weight and the
Motion to right and left given by a Cam with Grove fitted on Surface Roller
Shaft.
A Scraper made of Steel or other Metals fixed on the Wood Guide Bar by Screw
to Scrape the Top rollers and the turned up part of Scraper that prevents the Grease
or Accumulation Droping on the fibre substantially as described.
