We, JOHN HOLMES, of the firm of Fairbank and Holmes of Allerton, near
Bradford Yorkshire, Spinners, and ALFRED HOLMES of Allerton aforesaid, Manager
do hereby declare the nature of our invention for "IMPROVEMENTS CONNECTED
WITH THE TOP DRAWING ROLLERS OF GILL BOXES, DRAWING BOXES, AND FINISHING
AND, ROVING BOXES," to be as follows:-
Our invention has reference to the top drawing rollers employed in gill boxes,
drawing boxes, finishing and roving boxes for preparing worsted.
As is well understood in these machines the top drawing roller rests upon the
upper surface of a bottom roller, and is driven by frictional contact therewith, the
two rollers being kept closely in contact by screwed rods and weights. This
manner of driving the top drawing rollers was never considered satisfactory as in
addition to the said roller slipping the nip of the two rollers was so excessive as to
damage the fibre passing between them, and also caused the leather wrapt around
the top rollers to be soon worn away.
Our invention consists in fixing gear wheels onto the shaft of the said top
drawing roller by which means the said roller is driven positively, consequently
the nip of the rollers is not necessarily so keen as when driven by friction, there
is also no liability of slipping. The alubbing produced in the machine is now
much better, 'the yarn is also superior, and the leather around the top drawing
roller will. wear much longer, in consequence of there being less pressure put
upon' it.

I, JOHN HOLMES of the firm of Fairbank and Holmes, of Allerton, near Bradford,
Yorkshire Spinners, and ALFRED HOLMES of Allerton aforesaid, Manager do hereby
declare the nature of our invention for "IMPROVEMENTS CONNECTED WITH THE TOP
DRAWING ROLLERS OF GILL BOXES, DRAWING BOXES, AND FINISHING AND ROVING
BOXES," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
Our Invention has reference to the top drawing rollers employed in gill boxes,
drawing boxes, finishing and roving boxes for preparing worsted.
As is well understood in these machines the top drawing roller rests upon the
upper surface of a bottom roller, and is driven by frictional contact therewith,
the two rollers being kept closely in contact by screwed rods and springs. This
manner of driving the top drawing rollers was never considered satisfactory, as in
addition to the said roller slipping, the nip of the two rollers was so excessive as to
damage the fibre passing between them, and also caused the cloth and leather
wrapt around the top roller to be soon worn away.
Our invention consists in, fixing gear wheels onto the shaft of the said top
drawing roller, gearing into wheels on the end of the bottom roller shaft, by which
means the said roller is driven positively.
Such being the nature and object of our Invention, we will now proceed to
describe the same more fully, and for that purpose make reference to the accom-
panying Sheet of drawings wherein Fig. 1 is end view of a drawing box shewing
the application of our improved method of driving the front top drawing rollers,
Fig. 2 is section thereof. A is framing of machine, B the spindle and flyer, C the
bobbin upon which the fibre is wound, and D is the front bottom drawing roller,
and E the front top drawing roller all arranged in the ordinary manner.
Hitherto the bottom roller D has been driven by wheels, but the top rollers E
have only been driven by frictional contact with the bottom roller D, and in order
to make the driving as sure as frictional driving can be made, the screwed rod F
has been employed to draw the top roller against the bottom roller, the pressure
being regulated by the nut a but the pressure thereon has been so great as to
damage the fibre passing between the said rollers and has also worn away the cloth
and leather around the said rollers.
To avoid these disadvantages we drive the top roller by means of gear
wheels G. H. I and J consequently the nip of the rollers is not necessarily so keen
as when driven by friction, and there is no liability of slipping, whilst the slubbing
produced in the machine is now much better, the yarn is also superior, and the

page_text: cloth and leather around the top drawing rollers will wear much longer, in con-
sequence of the reduced pressure which necessarily reduces the power to drive
same, whilst the consumption of oil is also lessened.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim as our Invention is,
The positive driving of the front top drawing roller of gill boxes, drawing boxes,
finishing, and roving boxes, in manner, and for purposes substantially as set forth.
