Improvements relating to the Weighting of the Rollers of Spinning
Frames.
I, JOHN HALSON WEBSTER, of the Firm of David Webster and Son, of
Bervie, in the County of Kincardine, Scotland, Flaxspinner, do hereby declare
the nature of this invention to be as follows :-
This invention relates to improvements in spinning frames the object being to
lessen the wear and tear of the wooden pressing rollers by interposing an elastic
medium between such rollers and their levers and weights, thereby improving the
quality and increasing the production of the yarn.
In carrying out my invention I interpose between the wooden pressing rollers
and the pressing levers an elastic medium or buffer.
According to one modification the buffer may consist of a case which is hinged
or jointed to the pressing lever by a pin such case containing a steel spring or
rubber washer which acts against a guide into which is screwed the adjustable pad.
The guide is restrained by the pin from coming completely out of its case by the
action of the spring. The pin is free to move longitudinally in an elongated hole.
Provision for the varying sizes of the wooden pressing rollers is made by adjusting
the position of the pad relative to its guide.
In ordinary spinning frames where there is no elastic medium between the
pressing lever and the wooden pressing roller any inequality in the cylindrical
surface of such pressing rollers causes the pressing levera to vibrate. If the hand
he placed on such levers a hard jarring may be felt, such jarring causing the yarn
to be nipped and the wooden rollers to be destroyed.
By the use of the elastic buffer the hard jarring is quite softened, the yarn is not
nipped and consequently its quality is improved and the wooden rollers do not
deteriorate nearly so quickly.

Improvements relating to the Weighting of the Rollers of Spinning
Frames.
1, JOHN HALSON WEBSTER, of the Firm of David Webster and Son, of
Bervie, in the County of Kincardine, Scotland, 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 :-
This invention relates to improvements in spinning frames the object being to
lessen the wear and tear of the wooden pressing rollers by interposing an elastic
1

quality and increasing the production of the yarn.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended an explanatory sheet of drawings in which the same reference numerals
are used to indicate corresponding parts in all the figures where shown, that is
to say :-
Figure 1. is a part cross-section of a spinning frame showing how my invention
may be applied.
Figures 2. 3. 4. and 5. respectively show side and end views, and upper and
lower plans of the pressing lever when fitted with my invention.
Figure 6. is a section of the buffer at A. A. (Figure 7).
Figures 7. and 8. are respectively cross-sections of the buffer at B. B. and C. C.
(Figure 6).
In carrying out my invention I interpose between the wooden pressing rollers 10.
and the pressing levers 11. an elastic medium or buffer 12.
According to one modification the buffer may consist of a case 12. which is
hinged or jointed to the pressing lever 11. by a pin 13, such case containing
a steel spring or rubber washer 14. (a spiral spring is shown in the drawings)
which acts against a guide 15. into which is screwed the adjustable pad 16. The
guide 15. is restrained by the pin 17. from coming completely out of its case by
The action of the spring. The pin is free to move longitudinally in an elongated
hole 18. Provision for the varying sizes of the wooden pressing rollers is made by
adjusting the position of the pad 16. relative to its guide 15.
In ordinary spinning frames where there is no elastic medium between the
pressing lever and the wooden pressing ruller any inequality in the cylindrical
surface of such pressing rullers causes the pressing levers 11. to vinate. If the
hand be placed on such levers, a hard jarring may be felt, such jarring causing the
yarn to be nipped and the wooden rollers to be destroyed.
By the use of the elastic buffer the hard jarring is quite softened, the yarn is not
nipped and consequently its quality is improved and the wooden rollers do not
deteriorate nearly so quickly.
Having now particularly described and ascertained the nature of my suid inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
:-
(1.) In spinning frames, the use of an elastic medium or buffer between the
wooden pressing roller and the pressing lever, substantially as described and for
the purposes set forth.
(2.) In spinning frames, the combination and arrangement of parts consisting of
the wooden pressing roller 10, pressing lever 11, buffer 12, pin 13, spring 14,
guide 15, adjustable pad 16, pin 17. and elongated hole 18, substantially as
described and illustrated on the accompanying drawings.
