PROVISIONAL SPECIFICATION.
Improvements in Winding, Doubling, Ring Spinning Frames and
Throstles.
We, FRANK HARRY CLARKE, of Chestergate Works, and ALFRED THOMAS
MALVIN, of 45, Charles Street, both of Stockport, in the County of Chester,
Engineers, do hereby declare the nature of this invention to be as follows;-
This invention relates to improvements in winding, doubling, ring spinning frames
and throstles and has for its object to provide an improved form of cop or bobbin
building or taper motion which 18 much simpler in construction more reliable
in action and whereby the cops or bobbins are built much firmer at the nose
and not liable to be damaged through rough handling as heretofore has been
the case
To this end we provide the heart cam forming part of the cop or bobbin build-
ing or taper motion, at the highest point with a radially sliding bit forming a
continuation of the periphery of the heart cam and adapted to reciprocate con-
tinuously during the rotation of the heart cam and thereby cause the layers of
thread to be displaced in such a manner that one binds the other.
The said radially sliding bit or point 18 suitably let into or guided upon the
heart cam and reciprocated by a small cam fixed to the end of a short shaft
mounted in and rotating with the heart cam and having at its other end secured
a spur wheel whieh gears into another spur wheel or pinion arranged stationary
on the bearing in which the shaft to which the heart cam is secured is mounted.
As the heart cam 18 revolved by its shaft, the said stationary wheel or pinion
imparts rotary motion to the wheel on the said cam shaft by the latter rotating
around the former and the cam on the said shaft is thus caused to reciprocate
the said sliding bit or point continuously and at a rate which may be varied at
will by changing the size of the respective spur wheels

Improvements in Winding, Doubling, Ring Spinning Frames and
Throstles.
We, FRANK HARRY CLARKE, of Chestergate Works, and ALFRED THOMAS
MALVIN, of 45, Charles Street, both of Stockport, in the County of Chester,
Engineers, 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 winding, doubling, ring spinning frames
гр.

building or taper motion which is much simple in construction more reliable
in action and whereby the cops or bobbins are built much firmer at the nose
and not liable to be damaged through rough handling as heretofore has been
the case
And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Fig 1 being a side view and Fig 2
a cross section of our new form of heart cam, Fig 1 a side view of a modification
thereof at a large scale and Fig 3 an end view showing the heart cam applied to
a winding or doubling fiame
In carrying out our invention and referring to Figs 1 & 2, we form or provide
the heart cam a, a, generally employed in connection with cop or bobbin build-
ing or taper motion, in the class of machine referred to, at its highest point or
nose a¹ with a radially sliding bit b which forms a continuation and extension of
the periphery of the heart cam and is adapted to reciprocate continuously during
the iotation of the heart cam and causes in the winding of the cop or bobbin the
layers of thread to be displaced at the nose in such a manner that one binds
the other
The said radially sliding bit or point in the form of a plate, 18 suitably let
into o guided upon the heart cam and slowly reciprocated during the rotation
of the latter by a small came fixed to the end of a short shaft & mounted in and
1otating with the heart cam a, a¹ and having at its other end secured a spur
wheel f This spur wheel geais into another spur wheel or pinion y arranged
stationary on the bearing which carries the shaft to which is secured the
heart cam a, a¹
In the present instance the bit or point is let into a recess a² formed in
the side of the heart cam a, a and retained therein by a plate a' secured by
screws a (shown removed in Fig 1), an opening b being formed in the bit or
point near its inner end in which the cam e revolves, the sliding bit or point 6
being shown in Figs 1 & 2 in its outer position, e projecting from the highest
point or nose a¹ of the heart cam.
b
As the heart cam a, a¹ 18 1evolved by its shaft the stationary wheel or pinion g
imparts rotary motion to the wheel f on the shaft d, by the latter wheel rotating
around the former and the cam on the shaft d is thus caused to reciprocate
the said bit or point 6 continuously and at a rate which may be varied at will
by changing the size of the spur wheels g or for that of both
b
Referring to Fig 3 in which the bit or point is shown in its inner position, k, k
are the cam levers employed in a winding or doubling machine acted upon by the
heart cam a, a¹ and connected by chains 7, to the rail lifting blocks m, m
According to a modification of our invention the said sliding bit or point may
be extended across the heart cam, as shown in Fig 1, and thus the heel or hollow
of the cam also rendered extendible whereby cops or bobbins can also be wound
taper at the bottom
It is obvious that the improvements described may also be applied to ring
spinning frames and throstles without departing from the nature of our inven-
tion and that such application will be readily understood without being illus-
trated
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, I declare that what
I claim 18
1st In cop o bobbin building and tapering motions for winding, doubling,
ring spinning fiames and throstles, a heart cam a, a¹ having an automatically
reciprocated sliding bit or point b forming an extendible nose, substantially as
and for the purpose set forth.

page_text: 2nd. In a heart cam a, al having a sliding nose bit b, such as specified in the
preceding claim, reciprocating the said nose by means of a came and spur wheel
oi pinion gearing into and iotating with the heart cam a, a' around a stationary
spur wheel g, all substantially as and for the purpose set forth.
