PROVISIONAL SPECIFICATION.
Improvements in Machinery Employed in Twisting or Doubling
Yarn.
We GEORGE CLEGG, JOHN THOMAS, and WILLIAM HENRY HARRISON all of Miall
Street Mills, Halifax in the County of York, Worsted Spinners, do hereby declare the
nature of this invention to be as follows :-
:―
This invention relates to improved appliances to be used in connection with
machinery for purpose aforesaid and the object is to automatically sever and stop the
delivery of twist when necessary, without arresting the motion of the delivery roller
or rollers and to dispense with trap roller and much of the apparatus heretofore
employed on twisting and doubling machinery.
Apparatus constructed according to this our invention consists of a counterpoised
lever in one end of which is a pot eye or guide for the twist, and to the other end of
the said lever is attached a ^ or angled cutting instrument.
So long as the twist is in continuity and there is a sufficient tension thereon the
A cutter is held over or above the twist, but when from any cause the tension
and weight of the twist on the guide eye end of the lever is so reduced as to
perinit the said lever to tilt on its fulcrum the A cutter will descend on the twist and
the latter immediately wedges in the angle of the ^ and is cut or severed, thereby
preventing waste, imperfect twist or "single being made.
Dated this 7th day of March 1888.

page_text: Improvements in Machinery Employed in Twisting or Doubling
Yarn.
We, GEORGE CLEGG, JOHN THOMAS and WILLIAM HENRY HARRISON all of Miall
Street Mills Halifax in the County of York, Worsted Spinners, 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 improved appliances to be used in connection with
machinery for purpose aforesaid and the object is to automatically sever and stop the
delivery of twist when necessary without arresting the motion of the delivery roller or
rollers and to dispense with trap roller and much of the apparatus heretofore employed
on twisting and doubling machinery.
Apparatus constructed according to this our invention consists of a counterpoised
lever in one end of which is a pot eye or guide for the twist, and to the other end of
the said lever is attached a A or angled cutting instrument.
So long as the twist is in continuity and there is a sufficient tension thereon the
A cutter is held over or above the twist, but when from any cause the tension and
weight of the twist on the guido eye end of the lever is so reduced as to permit the
said lever to tilt on its fulcrum the A cutter will descend on the twist and the latter
immediately wedges in the angle of the A and is cut or severed, theroby preventing
waste, imperfect twist or "single" being made.
Such being the nature and object of this our invention, the following is a complete
description of same, reference being had to the accompanying drawings
Fig. 1 is a side elevation of our improved appliances for purpose aforesaid.
Fig. 2. is a front elevation of Fig. 1.
Fig. 3. is a side elevation of the improved appliances, shewing position of same when
the thread or yarn is broken, cut, or weakened.
According to this our said invention the appliances consist of a counterpoised
lever 1 free to move on its carrying stud 2 which is bolted to the frame 3 and in one
end of the lever I is a pot oyo 1 which serves as a guide or oye through which
the twist, thread or yarn 5 passes and at the opposite end of the said lever 1 is a
A shaped or angled cutting instrument 6.
The yarn, thread, or twist 5 passes from the bobbin, through and between the
guides 7. 7. and between or below the angle of the A or angled cutting instrument 6
and thence between the rollers 7-7 and from these to the pot. eye, or guide 4 & to
the spool.
The action is as follows:—
So long as the twist, yarn, or thread 5 is in continuity and there is a sufficient
tension thereon, and on the pot eye, or guide 4, the cutter is held over and above
the yarn or twist 5, but when from any cause the tension and weight of the yarn or
twist 5 on the pot eye or guide 4 and end 9 of the lever 1 is so reduced as to allow
the said lever 1 to tilt on its fulcrum stud 2 the V cutter 6 will descend on the twist

page_text: or yarn 5 and the latter immediately wedges in the angle of the V cutter 6, or is
cut or severed, thereby preventing waste, imperfect twist, or "single" being made
(see Fig. 3).
It will be seen by the above that the end 8 of the lever 1 is slightly heavier than
the end 9 of the lever1 and the balance of the same can be nicely adjusted by the move-
able weight. 10, as for a slender twist or yarn the V cutter 6 will not be required to
descend so heavily as for a stronger twist and vice versa. The end 9 of the lever 1
can be turned up on its hinge 11 to facilitate doffing.
Having now particularly described and ascertained the nature of this our said Inven-
tion, and in what manner the samo is to be performed, we declare that what
wo claim is :-
A hinged counterpoised lever having a thread guide or pot eye at one of its ends
the other oxtremity having a ^ or other shaped cutting or staying instrument all in
combination and for purpose herein fully described.
