PROVISIONAL SPECIFICATION.
Improvements in or applicable to "Twiners" Used for Doubling
Yarn.
We JOHN THOMAS TETLOW of 23 Werneth Hall Road, Doubler, and
WILLIAM STEVENS of 2 Malby Street, Insurance Agent, both of Oldham, in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to improvements upon the apparatus for which Letters
Patent No. 13381 were granted to Thomas Tetlow and John Thomas Tetlow
dated November 5th 1885.
It has been found in practically using the guide for which the above patent was
granted that after a certain point in the outward traverse of the slide, the position
of the yarn in the slits or slots of the guide was stationary or nearly so for the rest
of the traverse, and consequently the yarn wore notches in the slits or slots of the
guide at that point; and the principal object of the present invention is to
prevent the formation of these notches which allow dirt and imperfect places to
pass through.
For this purpose we mount the guides upon light movable rails capable of rising
and falling, and we give to these rails a slight vertical motion, up or down, at that
part of the traverse of the slide where the yarn is practically at a constant height,
so that the yarn is never passing through the slits or slots in the guide at any one
point in the said slits or slots more than at another part, and there will be no
tendency to wear the sides of the said slits or slots into notches.
"
The rails upon which the guides are mounted slide preferably upon vertical pegs
fixed in brackets attached to the "slide so that they can be readily removed and
changed for various counts of yarn.
"The rails are or may be raised and lowered by bell crank levers actuated by
bosses or projections on a long rod or rods beneath the rails, carried in suitable
brackets fixed to the "slide," the said rod or rods being capable of sliding end wise
in these bearings and actuated by cranks or arms at either end thereof, extending
downwards and provided with a bowl at their lower end working against the side
of rails or guides fixed to the floor and inclined to the required extent to raise or
lower the rails which carry the yarn guides.

and by the following statement :-
This invention relates to improvements upon the apparatus for which Letters
Patent No. 13381 were granted to Thomas Tetlow and John Thomas Tetlow
dated November 5th A.D. 1885.
It has been found in practically using the guide for which the above patent was
granted that after a certain point in the outward traverse of the slide the position.
of the yarn in the slits or slots of the guide was stationary or nearly so for the rest
of the traverse and consequently the yarn wore notches in the slits or slots of the
guide at that point; and the principal object of the present invention is to
prevent the formation of these notches which allow dirt and imperfect places to
pass through.
For this purpose we mount the guides upon light movable rails capable of rising
and falling and we give to these rails a slight vertical motion up or down at that
part of the traverse of the slide where the yarn is practically at a constant height
or if preferred during the whole traverse of the slide so that the yarn is never
passing through the slits or slots in the guide at any one point in the said slits or
slots more than at another point and there will be no tendency to wear the sides of
the said slits or slots into notches.
The rails upon which the guides are mounted slide preferably upon vertical_pegs
fixed in brackets attached to the "slide" so that they can be readily removed and
changed for various counts of yarn.
The rails are or may be raised and lowered by bell crank levers actuated by
bosses or projections on a long rod or rods beneath the rails carried in suitable
brackets fixed to the "slide" the said rod or rods being capable of sliding endwise
in these bearings and connected by links to a crank or lever at either end thereof
or at the headstock end only extending downwards and provided with a bowl at
the lower end thereof working against the side of a rail or guide fixed by brackets
to the floor or to the frame of the headstock and inclined to the required extent to
raise or lower the rails which carry the yarn guides.
In order that our invention may be clearly understood we have annexed hereto
a sheet of drawings illustrating the application thereof which we prefer and we
have marked the same with figures and letters of reference corresponding with
those of the following description.
Fig. 1 is a front elevation and Fig. 2 a plan view shewing so much of the
headstock and adjacent parts of a "twiner as is necessary to illustrate our
invention.
"
Fig. 14, is a sectional elevation of part of the slide and the yarn guide and its
rail detached and drawn to a larger scale.
a is the framework of the headstock, b is the slide and 12 two of the rails or
boards carried thereon, c are the spindles and d is the thread guide through which
the yarns pass from the creel e (Fig. 2) to the spindles c. Each guide d is made
of suitable length (say 3 feet) about four or five guides being attached to a movable
rail d' (preferably of wood) of suitable length capable of sliding upon vertical
pegs d² or their equivalent; the number of these guides and rails used will of
course depend upon the number of spindles on the "twiner." The rails d' are or
may be raised or lowered by bell crank levers d³ actuated by collars or pro-
jections upon rods g connected by links g' to a crank or lever / pivotted at h+ to
the slide b. This lever extends downwards and preferably carries at its lower
end a bowl held by a spring h² (or its equivalent) against a rail i fixed to the
headstock frame a.
The rail i is so inclined as to give the required motion up or down to the rails d
as the slide b recedes from the spindles c.
The rail may be inclined from end to end of the headstock, as shewn, in which
case the guide rails d' will preferably rise as the slide recedes from the spindles as
shewn dotted on Fig. 14, or as before stated it may only be inclined at that part of
the motion of the slide where the yarns would remain stationary in the slots in the

page_text: guides d were the latter not to move; or the rails d¹ may be lowered by the
incline during the receding motion of the slide b, or only at part of the motion,
and such falling motion may be given more rapidly and only at part of the motion
of the slide.
We would here remark that we do not confine ourselves to the precise mechanism
shown by the drawings and above described, as such mechanism may evidently be
varied so long as the principle of our invention is retained, which consists in means
for raising or lowering of the guides d by or during the motion of the slide in order
that the rise and fall of the yarns in the slots in the guides d may be continuous
and never so slow as to be practically arrested at any point in the length of the
said slots during the motion in or out of the said slide.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In a "twiner" for doubling yarn the combination of a guide plate capable of
vertical motion with suitable means for imparting such motion substantially as and
for the purposes herein before set forth.
