Improvements in Drawing Frames.
I, DAVID WEBSTER, of the firm of David Webster and Son, of Bervie, in the
County of Kincardine, N.B. Flaxspinner, do hereby declare the nature of this
invention to be as follows :-
My said invention is applicable to drawing frames for flax, tow, jute and the
like and has for its object to keep clear the leather pressing rollers of adherent
fibres, that is to say to prevent such fibres from lapping round the rollers.
In existing machines the leather pressing rollers are, in an imperfect way, kept
clean by means of rubbers composed of metal, wood, and plaiding, which rest on
their tops, or by means of rotating rollers similarly situated.
In carrying out my invention I apply the rotating rubbing rollers at the sides of
the leather pressing rollers, with their axes in the same plane--which is approxi-
mately horizontal-and with the rubbing rollers at the side next the delivery.
rollers. Both the pressing and the rubbing rollers rotate in the same direction,
hence their surfaces which are in contact, move in opposition.
By applying the rotating rubbing rollers in the manner described, any fibres
which may tend to rise and lap round the leather pressing rollers are struck down,
or laid, and pass on to the delivery rollers with the rest of the sliver.
Dated this 29th day of October 1892.

Improvements in Drawing Frames.
I, DAVID WEBSTER, of the firm of David Webster and Son, of Bervie, in
the County of Kincardine, N.B. Flaxspinner, 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 :-
My said invention is applicable to drawing frames for flax, tow, jute and the like,
and has for its object to keep clear the leather pressing rollers of adherent fibres,
that is to say to prevent such fibres from lapping round the rollers.
In existing machines the leather pressing rollers are, in an imperfect way, kept
clean by means of rubbers composed of metal, wood, and plaiding, which rest on
their tops, or by means of rotating rollers similarly situated.
And in order that my said invention may be properly understood, I now proceed
to particularly set forth the system, mode or manner, in or under which the same
is or may be used, or practically carried into effect, reference being made to the
accompanying drawings and to the letters and figures marked thereon, that is
to say :-
Figure 1. is a part sectional elevation looking on A. A. (Figure 2), and Figure 2.
is a part front elevation looking on B. B. (Figure 1.) of a drawing frame fitted
with my improvements.
In carrying out my invention I apply the rotating rubbing rollers 3. at the
sides of the leather pressing rollers 4, with their axes, namely the axes of the
rollers 3. and 4. in the same plane-which is approximately horizontal-and with
the rubbing rollers at the side next the delivery rollers 5. Both the pressing
rollers 4. and the rubbing rollers 3. rotate in the same direction, as shewn by
the arrows, hence their surfaces which are in contact, move in opposition. The

page_text: rubbing rollers 3. are preferably covered with plaiding 6, such rollers being driven
by means of the pulleys 7. and 8. and the belt 9.
By applying the rotating rubbing rollers 3. in the manner described, any
fibres, such as 10, which may tend to rise and lap round the leather pressing
rollers 4. are struck down, or laid, and pass on to the delivery rollers 5. with the
rest of the sliver.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
In drawing frames for flax, tow, jute and the like :-
(1) The improved system, mode or manner in or under which the same is or
may be used or practically carried into effect, substantially as and for the
purposes herein set forth, together with any mere modification or modifications
thereof.
(2) The improved combination and arrangement of parts hereinbefore described
and illustrated in the accompanying drawings.
(3) The use of the rotating rubbing rollers 3. substantially as and for the
purposes set forth.
