PROVISIONAL SPECIFICATION.
Improvements in Traverse Guides for Ring and other Spinning
Frames.
I, JAMES BURTINSHAW, of Lever Street Tin Works, Manchester, in the
County of Lancaster, Metal Worker, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the traverse guide by which the sliver or partly spun
yarn is directed between the rollers at the back of the frame.
These guides have hitherto been usually constructed with an eyelet hole stamped
therein or with a slot formed by mounting or attaching one or more pieces of wire
above the edge thereof to form a slot either open or enclosed.
This invention is designed to provide an elongated eye or slot in the traverse
guide which instead of being constructed by affixing wires or plates to the guide
and open at the top will be stamped out of and formed in one piece therewith.
In carrying out the invention I punch or cut out in the sheet metal from which
the guides are constructed a slot or elongated eye and at the same time punch or
cut away the metal adjacent to the slot leaving only a narrow margin of metal
surrounding it so that each slot will stand out separately with a free space
intervening between one and the next. The metal containing the slot which thus
stands up is then twisted or bent round to bring the two inner edges of the slot
into the same or approximately the same plane so that as soon as the direction of
movement of the guide is reversed at either end of its traverse it will at the same
time reverse the lateral movement of the sliver or yarn.
An eyelet of elongated form is fixed in the slot in the usual way to strengthen it
and present a smooth or even edge to the material passing through. Or it may be
beaded either completely round or for a part of the way and in the latter case the
bottom of the slot may be cut to such a shape that the metal will securely hold
the bead in position.
The metal left around the slot may be stamped or beaded if desired for the
purpose of strengthening or stiffening it.

COMPLETE SPECIFICATION.
Improvements in Traverse Guides for Ring and other Spinning
Frames.
I, JAMES BURTINSHAW, of Lever Street Tin Works, Manchester, in the
County of Lancaster, Metal Worker, do hereby declare the nature of this inven-
tion 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 traverse guide by which the rove or partly spun
yarn is directed between the rollers at the back of the frame.
These guides have hitherto been usually constructed with an eyelet hole stamped
therein or with a slot formed by mounting or attaching one or more pieces of wire
above the edge thereof to form a slot either open or enclosed.
This invention is designed to provide an elongated eye or enclosed slot which
instead of being constructed by means of wires bent or curved to the required

page_text: Fig. 4, pian.
Fig. 5, modified form.
I cut or punch out from the sheet metal a slot or elongated eye A and at the
same operation cut away the adjacent metal leaving only a narrow margin of metal
surrounding it so that the slot will be contained in a strip of metal B.
The slot so formed is strengthened and the edges protected and rendered smooth
by an eyelet a of elongated form compressed and secured around the edges. This
presents a smooth and even edge to the material passing through. Or the slot
may be beaded either completely round or for a part of the way and in the latter
case the bottom of the slot may be cut to such a shape that the metal will securely
hold the bead in position.
The strip of metal B containing the slot A is set at an angle or twisted round as
shown to bring the two inner edges of the slot into the same plane or approximately
the same plane at right angles to the longitudinal axis of the rollers one in advance
of the other so that as soon as the direction of motion of the guide is reversed at
either end of its traverse it will at the same time reverse the lateral movement of
the sliver or yarn..
The strips B may be mounted upon and soldered to the base piece D as in
Figs. 1 to 4 or they may be cut or stamped out therefrom and remain in one piece
therewith as in Fig. 5.
The metal around the slot A in the strips B may be stamped or beaded if
desired for the purpose of strengthening or stiffening it.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A traverse guide for ring and other spinning frames constructed with an
elongated eye or enclosed slot A stamped out in a strip of metal B and protected
around its edges by an oblong eyelet affixed therein substantially as described and
shown.
