Improvements in Drawing Frames for Fibrous Materials.
MATTHEW MONTGOMERY, 4, Woodbrook Villas, Whiterock Road, Belfast, Mill
Manager, do hereby declare the nature of this invention to be as follows:-
This improvement relates to means of automatically cleaning & keeping free
of loose fibres the front or drawing roller and retaining rollers of drawing frames.
And consists in the application of a sliding reciprocating scraper or scrapers
touching the rollers & working parallel to their axes.
The reciprocating motion is obtained by the use of any of the well known
mechanical motions actuated by means of moving parts of the frame.
The reciprocating scraper or scrapers may be applied independantly to each head
or to the whole frame.
The advantages gained are any fibres which tend to accumulate and cling
between the rollers and the usual cleaning rubbers are by the use of these means
removed at once. thus preventing accumulation of fibres which otherwise would be
ultimately carried away with the sliver thereby causing, lumps and making the
sliver unequal in thickness it being impossible to get rid of these lumps &
inequalities in the after process of spinning.

Improvements in Drawing Frames for Fibrous Materials.
I, MATTHEW MONTGOMERY, 4, Woodbrook Villas, Whiterock Road, Belfast, Mill
Manager, 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:
---
This improvement relates to means of automatically cleaning & keeping free of
loose fibres the front or drawing roller & retaining rollers of drawing frames,
and consists in the application of a sliding reciprocating scraper or scrapers
touching the rollers and working parallel to their axes.
The reciprocating motion is obtained by the use of any of the well known
mechanical motions actuated by moving parts of the frame.
The advantages gained are any fibres which tend to accumulate & cling between
the rollers and the usual cleaning rubbers are by the use of these means removed
at once thus preventing accumulation of fibres which otherwise would be ulti-
mately carried away with the sliver thereby causing lumps and making the sliver

in the after process of spinning. Such being the nature & object of my inven-
tion the following is a complete description of same reference being had to the
accompanying sheet of drawings, in which Fig. I shews as much of the end
elevation of a drawing frame as will shew the nature of my invention. Fig. II
is a front elevation of Fig. I.
In the drawings the sliding reciprocating scraper is shewn as applied to the
drawing roller of a drawing frame.
At 1 is the front or drawing roller. 2 is the ordinary cleaning rubber & 3 is
the sliding reciprocating scraper, this scraper being mounted on rod 4 & is caused
to slide backwards and forwards on this rod 4 in the direction of the arrows by
means of the following mechanism.
5 is a wheel driven by a rotating part of the drawing frame a connecting rod 6
joins the wheel 5 to the lever 7, this lever being fixed to the shaft 8 which carries
a bevil wheel 9 gearing into a bevil wheel 10 carried on a shaft or stud 11 which
also carries a chain wheel 12.
The sliding reciprocating scraper 3, is connected to the chain wheel 12 by the
chain 13; 14 & 14, being guide wheels for the chain 13.
The action is as follows on the wheel 5 rotating the action of the connecting
rod 6 causes the lever 7 & the shaft 8 & wheel 9 to oscillate or rock, this in turn
causes the bevil wheel 10 & the chain wheel 12 to rock as indicated by the arrows
-& the scraper 3 being connected by means of the chain 13 to the wheel 12 is
caused to slide backwards and forwards.
As the fingers of the scraper touch the roller any loose fibres that tend to cling
between the roller and the rubber are at once removed which otherwise would
gather & be carried away with the sliver thereby causing lumps & making the
sliver unequal it being impossible to get rid of these lumps in the after process
of spinning.
Having now particularly described and ascertained the nature of my said
invention & in what manner the same is to be performed I declare that what I
claim is-
In drawing frames the use of a sliding reciprocating scraper or scrapers applied
to the drawing or retaining rollers for the purpose of keeping the rollers free of
loose fibres that tend to accumulate & cling between the rollers & the usual
cleaning rubbers.
