Improvements in Apparavu
Year: 1897

page_text: We, CHARLES HAULO and CHARLES EDWARD LIEBREICH, of Mill Street, Bradford,
in the County of York, Machinists, do hereby declare the nature of this invention
to be as follows:-
-
This invention has for its object, certain improvements whereby we are enabled
to utilize ordinary spool bobbins, in place of pirn bobbins, on that class of winding
frames, on which the pirn bobbins are driven by spindles and the bobbins raised
as the yarn is built thereon by revolving cones; and to build the yarn on the spool
bobbins in such a manner that, it will readily leave the bobbins in the required
manner when weaving, and is not liable to "fluff," that is, to leave the bobbins in
bulk, as is the case when the yarn is wound thereon by machines of the ordinary
construction; also to combine with the winding frame certain mechanism by which
the tension on the yarn is readily adjusted.
In carrying out our object, we mount an oscillating guide bar in front of the
cones which support the bobbins, and between the oscillating guide bar and the
creels or the like, we suspend a tension device, consisting of two or more bars
mounted in a frame, which may be adjusted and secured in such positions that,
the drag or tension on the yarn is increased or diminished in accordance with the
angle in which the bars are secured.
The yarn on leaving the tension bars, is conducted over the oscillating guide
bar which is operated in such a manner that, there is a quick up and down move-
ment imparted thereto, with a stoppage or dwell at the termination of the stroke,
the quick motion causing the threads of yarn to be wrapped around the bobbin
with a variable crossing motion.

We, CHARLES HAHLO and CHARLES EDWARD LIEBREICH, of Mill Street, Bradford,
in the County of York, Machinists, 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 has for its object, certain improvements whereby we are enabled
to utilize ordinary spool bobbins in place of pirn bobbins, on that class of winding
frames on which the pirn bobbins are driven by removable spindles and raised as

page_text: the yarn is built thereon by revolving cones, and to build the yarn on the spool
bobbins in such a manner that, it will readily leave the bobbins in the required
manner when weaving; and is not liable to fluff," that is, to leave the bobbins
in bulk, as is the case when the yarn is wound thereon by machines of the ordinary
construction; also to combine with the winding framme certain mechanism by which
the tension on the yarn is readily adjusted.
In describing our invention in detail, reference is made to the accompanying
sheet of drawings, in which Fig. 1 represents an end elevation of a portion of a
winding frame made according to our invention, part of the end frame of the
machine is cut away, in order to more clearly illustrate and explain the action of
the machine.
Fig. 2 is a front elevation of a portion of the winding frame.
Fig. 3 is a detached detailed elevation of the cones drawn to a larger scale.
Fig. 4 is a plan thereof, and
Fig. 5 is a detached detail of a wharl, cones and spool bobbin, the latter partly
filled with yarn.
Similar letters indicate similar parts where they appear.
The creel bobbins A, on which the hanks of yarn 'B, are placed for winding, are
mounted upon the bars C. and levers D. supported by shaft E, the levers D. being
suspended on the bars C. and provided with adjustable weights F. as in ordinary
machines.
The rails G. and H. are secured to the end frames J. and upon the rails G. are
secured a number of small brackets supporting the wharls K. driven by bands L.
from the rotating cylinder M. mounted and driven in any convenient manner,
and to the top rail H. are secured brackets supporting the cones N, three cones
being mounted on each bracket.
The spool bobbins O. are of the ordinary construction having a flange or head
at one end of the bobbins only, the barrel of the bobbins being parallel or of
slight taper for the whole length towards the end without a flange, and differ from
what are known as pirn bobbins, in as much as, the barrel of the latter is parallel
or slightly taper for some distance, but the remainder of the barrel tapers quickly,
increasing in diameter to the head of the bobbin.
The spool bobbins 0. are placed between the three cones N, the ends of the
spools when empty or clear of yarn, resting upon the top of the respective
wharls K, the flanges or heads being between the said cones. A movable spindle S
which may be square or oblong in section is passed through the hole in the centre
of each bobbin, and is of such length as to engage with a hole of similar section
formed in the upper portion of each wharl, the said spindle extending into the
wharl for some distance acts as a support to the bobbin, and in addition causes
the bobbin to rotate by reason of the weight of the spindle resting upon the bobbin.
The yarn B. to be wound upon the spool bobbins 0. is conducted from the
creel bobbins A. over the tension bars P. P. and over the oscillating bar Q. to
the spool bobbins O. rotated between the cones N. by the wharls K. in the manner
as hereinbefore described, the yarn being built upon the said bobbins in a manner
that, each bobbin is filled with yarn close to the spool head, and is so crossed and
guided by the oscillations of the bar Q. that when weaving the yarn built thereon,
it leaves the bobbins regularly, without "fluffing."
The oscillating guide bar Q. is supported by a number of arms R. secured to the
shaft T, to the end of which is attached an arm U. connected by rod V. to the
lever W. provided with a small roller Y. which is held in contact with a rotating
cam Z. by spiral spring 1, the rotating cam being driven by spur wheels 2. and 3.
The yarn on leaving the creel bobbins A. passes over the tension bars P. held
together by links 4, the top bar being supported by brackets 5. in a manner that
the said bar may turn therein and thereby vary the angle of the bars as shown by
dotted lines in relation to the spool bobbins 0. on the movable spindles, by which
variation of angle, the tension on the yarn is increased or diminished according to
the angle at which the said bars are placed.
The yarn on leaving the tension bars P. is conducted over the oscillating guide
...:

page_text: bar Q. which is operated by the rotating cam Z. through the intermediary con-
necting levers in a manner that, a varying quick up and down movement is
imparted thereto, and at the termination of the up and down stroke or traverse,
a stoppage or dwell given to the said guide bars. The varying quick up and
down motion causes the threads of yarn to be wrapped around the bobbins with
variable crossings, and not in comparative circles at about right angles to the axis
of the bobbins, so that by the peculiar build of the yarn upon the bobbins, it is
held thereon by the threads overlapping in a manner that, they cannot leave the
bobbins in bulk, as is the case when built thereon in the ordinary manner.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, we declare that what we
claim is,
.
A winding frame in which are combined the tension bars P. with a rotating
cam Z. and oscillating guide bar Q, arranged and operated substantially in the
manner as shown and described and for the purpose as hereinbefore set forth.
