Year: 1898

page_text: PROVISIONAL SPECIFICATION:
Improvements in Ring Spinning and Doubling Frames.
I, SAMUEL HOPWOOD, of 15, Vaugh Road, Heaton Norris, Stockport, in the
County of Chester, Over-looker, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in ring spinning and doubling frames
and has for its object to provide means whereby the bobbins can be wound to
cop shape and thus a great deal of waste saved in doubling and spinning.
In accomplishing this I dispense with the screw and ratchet wheel hitherto
carried by the cam lever of the rail lifting motion and employ in lieu thereof,
a ratchet wheel upon the bolt by which the rail lifting chain is secured to its
quadrant.
-
This ratchet wheel is caused to bear against the end of the said quadrant and
is intermittently rotated on the said bolt, i.e. turned one tooth each time the ring
rail rises or falls, by coming into contact with a stationary inclined wire or rail,
secured to the bolster rail by means of two brackets.
By the described arrangement the bobbin is shortened at the bottom and
lengthened at the top in one lift and thereby shaped same as a cop.

Improvements in Ring Spinning and Doubling Frames.
I, SAMUEL HOPWOOD, late of 15, Vaugh Road, Heaton Norris, now of 149,
Chestergate, Stockport, in the County of Chester, Over-looker, 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 ring spinning and doubling frames
and has for its object to provide means whereby in such machines the bobbins
can be wound to cop shape in the manner as hereinafter described and thus a
great deal of waste saved in doubling and spinning.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a side elevation of the driving end of a ring spinning and doubling
[Price 8d1

page_text: frame showing my improvements applied. Fig. 2 is a vertical cross section at
line A-A Fig. 1, Figs. 1 & 2 are respectively a plan and section detached.
In carrying out my invention and referring to the figures generally I dispense
with the screw and ratchet wheel hitherto carried by the cam lever a of the rail
lifting motion and employ in lieu thereof, the ratchet wheel 6 upon the bolt c by
which the rail lifting chain d is secured to its quadrant e.
This ratchet wheel is caused to bear against the end e¹ of the quadrant e and
is intermittently rotated on the bolt c .e. turned one tooth each time the ring
rail falls, by coming or moving in contact with a stationary inclined wire or
rail g or other suitable means giving it the desired turn. This wire or rail 9 is
secured to the bolster rail by two brackets or by other suitable means, say by
bending its ends around the bolster rail h, see more particularly Figs. 1* & 2*.
The said ratchet wheel being internally threaded conform with the thread on
the chain bolt c, when turned by the said inclined rod or rail during the fall of
the ring. rail gradually shortens the rail lifting chain d.
When the bobbins have been finished and doffed, the said ratchet wheel b is
turned back by hand to the outer end of the lifting chain bolt c which is fur-
nished with a collar or nut c¹.
By the described arrangement the bobbin is shortened at the bottom and
lengthened at the top in one lift and thereby shaped as a cop, i.e. formed taper
at the bottom and top, the first layer of thread extending from the bottom of
the bobbin to the base of the taper to be formed at the top of the bobbin and
every successive layers being gradually displaced upwards until the bobbin is
finished.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim, is:
1st. In ring spinning and doubling frames, the use of mechanism for building
cop shaped bobbins in the manner substantially as hereinbefore described.
2nd. In ring spinning and doubling frames, a ratchet wheel b employed upon
the bolt c of the rail lifting chain d, in combination with a stationary incline
or the like g adapted to intermittently turn the said ratchet wheel and the latter
to shorten the rail lifting chain d for the purpose of building a cop shaped bobbin
in the manner and substantially as set forth.
