PROVISIONAL SPECIFICATION.
An Improvement in Apparatus for Winding Yarn or Thread.
I HENRY WREN of the firm of Henry Wren and Company of London Road Iron
Works, Manchester in the County of Lancaster, Engineer, do heroby declare the
nature of this invention to be as follows:-
"
وو
This invention relates to the construction of the traverse motion of that class of
machines used for winding yarn or thread known as * cross winding frames or "quick
traverse frames" the object of the invention being to prevent the fault known as
cobwebbing" which is caused by the wearing away of the point of the traverse cam,
allowing of a slight "dwell" at the point of crossing, which wearing away also causes
an objectionable noise by the shaking or rattling of the bowl in the groove of the
traverse cam as it passes that point.
My invention consists in the construction and use of a noiseless adjustable spring
buffer cam for this purpose which is constructed as follows :-
I make the extreme crossing point of the cam of a separate piece which can be
renewed when desirable, and may either be made of hardened steel or other suitable
wear resisting material, and it is fixed in its place by means of a screw or similar
device, so that when this point becomes worn it can readily be renewed without the
necessity for an entire fresh cam.
I also remove a portion of the concave part of the groove of the cam which is
opposite to the said crossing point and I insert therein a loose piece of hardened steel
or other suitable material which is capable of a certain amount of sliding motion
towards and from the opposito point of the cam and is backed up by a spring or
springs.
The latter is adjustable by means of a screw, and this loose piece acts as a spring
buffer reducing both the wear of this part and also the noise of working.
A spring or springs may also be placed at the back of the nose piece or point for
the same purpose.

I HENRY WREN of the firm of Henry Wren and Company of London Road Iron
Works Manchester in the County of Lancaster Engineer 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 the construction of the traverse motion of that class of
machines used for winding yarn or thread known as cross winding frames
quick traverse frames" the object of the invention being to prevent the fault known
as " cobwebbing" which is caused by the wearing away of the point of the traverse
cam allowing of a slight "dwell" at the point of crossing, which wearing away also
causes an objectionable noise by the shaking or rattling of the bowl in the groove of
the traverse cam as it passes that point.
My invention consists in the-construction and use of a noiseless adjustable spring
buffer cam for this purpose; and the invention will be readily understood on reference
to the accompanying drawings and the following description thereof.
Fig. 1 is a front elevation. Fig. 2 an end elevation., Fig. 3. is a sectional

elevation taken through the line A, B on Fig. 1; and Fig. 4. a sectional elevation
taken through about the line C. D, E F on Fig. 2.
I make the extreme crossing point of the cam of a separate piece (see Figs. 1. 3
and 4) which can be renewed when desirable, and may either be made of hardened
steel, or other suitable wear resisting material, and this piece a is fixed in its place
by means of a screw or similar device, so that when this point becomes worn it can
readily be renewed without the necessity for an entire fresh cam.
I also remove a portion of the concave part of the groove of the cam which is
opposite to the said crossing point & and I insert therein a loose piece c of hardened
steel or other suitable material which is capable of a certain amount of sliding motion
towards and from the opposite point of the cum, and is backed up by a spring or
springs d.
The latter may be adjustable by means of a screw and this loose piece c acts
as a spring buffer reducing both the wear of this part and also the noise of
working.
A spring or springs may also be placed at the back of the nose piece or point a for
the same purpose.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
A noiseless spring buffer cam constructed substantially as and for the purposes
areinhetorn described
