We, BENJAMIN ALFRED DOBSON, Machine Maker of the firm of Dobson and Barlow,
of Kay Street Works Bolton in the County of Lancaster and JOHN HILL, Foreman,
of the same place, do hereby declare the nature of this Invention to be as follows:-
In gassing frames of the ordinary construction hobbins with a head or flange at
each end are commonly used the flanges fitting over the sides of the driving drum to
hold the bobbin in its position the width of the drum determining the length of
bobbin on which the yarn can be wound when gassed.
The object of our Invention is to wind the yarn or other fibrous material after it
has been gassed on to wooden bobbins without heads or flanges conical bobbins or
tubes or on paper tubes by which means we can wind more yarn on each bobbin thus
making less knots and waste and increasing the production of the machine.
We effect this by a quick traversing guide the yarn is brought as usual from the
creel to the gas lights then passed over a regulating rod and through the traversing
guide which instead of being some distance from the bobbins is according to our
Invention placed close to the nip of the bobbin and drum. This guide is preferably
trumpet mouthed open or cut through at the top and so placed as to require no
threading of the yarn when piecing up or starting a bobbin Each guide is fastened
to a rod which receives a to and fro traverse motion by its connection to a slide bar ;.
fixed to this bar is a bowl working in the groove of a cam driven from the end of the
drum shaft or the traverse motion may be given in other convenient manner.
We can by a motion given by a screw or cranked lever or other suitable means
vary the traverse of the yarn on the bobbin every layer so as to build bobbins with
conical or taper ends as in a fly frame bobbin and this whether the body of the bobbin
is parallel or conical.
Yarn wound on tubes in the manner described can be reeled more quickly than that
wound on bobbins with heads as in the first case the yarn runs freely off stationary
bobbins avoiding the drag which is caused by the yarn having to pull flanged bobbins
round on their spindles as now customary.

page_text: Improvements in or relating to Frames for Gassing Yarns.
We, BENJAMIN ALFRED DOBSON, Machine Maker, of the firm of Dobson and Barlow,
of Kay Street Works, Bolton in the County of Lancaster and JOHN HILL Foreman
of the same place, 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 :-
In gassing frames of the ordinary construction bobbins with a head or flange at
each end are commonly used the flanges fitting over the sides of the driving drum to
hold the bobbin in its position, the width of the drum determining the length of bobbin
on which the yarn can be wound when gassed.
The object of our Invention is to wind the yarn after it has been gassed on to
wooden bobbins without heads or flanges conical bobbins or iubes or on paper tubes
by which means we can wind more yarn on each bobbin thus making less knots and
waste and increasing the production of the machine:
We effect this by a quick traversing guide, the yarn being brought as usual from
the creel to the gas lights, then is passed over a regulating rod and through the
traversing guide which, instead of being some distance from the bobbins, is, according
to our Invention, placed close to the nip of the bobbin and druip. This guide is
preferably trumpet mouthed open or cut through at the top and so placed as to require
no threading of the yarn when piecing up or starting a bobbin. Each guide is
fastened to a rod which receives a to and fro traverse motion by its connection to a
slide bar fixed to this bar is a bowl working in the groove of a cam driven from the
end of the drum shaft or the traverse motion may be given in other convenient
manner.
We can by a motion given by a screw or cranked lever or other suitable means vary
the traverse of the yarn on the bobbin every layer so as to build bobbins with conical
or taper ends as in a fly frame bobbin and this whether the body of the bobbin is
parallel or conical.
And in order that our Invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of Drawings reference being had to
the figures and letters marked thereon.
Figure 1 is a side view and Fig. 2 a front view of a frame, for gassing yarns, to
which our improvements have been applied. Fig. 3 is a detail view of some of the
paris shown in Fig. 1 but in different positions. Fig. 4 is an end view of the cam
and quick traversing guide. Figs. 5 and 6 are full size views of the traversing guide.
Figs. 7 and 8 are two views of a suitable arrangement of mechanism which may be
employed according to our Invention for winding bobbins with taper or conical
ends and Fig. 9 is a plan view of Fig. 7.
Referring first more particularly to Figs. 1 to 6.–
-a designates a part of the stand
or frame, 6 one of a series of cops from which the yarns are being unwound, c an

page_text: arrangement of lights for gassing the yarns, & the regulating rod over which the yarns
pass to the series of traversing guides e through which they pass to the series of
Hlangeless bobbins or tubes : one of the guides e is shown full size in the two detail
views Figs. 5 and 6 which clearly represent the form and construction of guide we
prefer to employ. The traversing guides e are mounted on a rod e¹ and are according
to our Invention so placed that the front ends of the said guides almost enter the nip
of the bobbins and driving drums g. The series of drums g are secured upon
the drum shaft g' which takes its motion by means of a pinion g² from a spur wheel g³
fixed on the revolving cam shaft which is carried in a bracket bolted adjustably to
the frame and on the shaft is also fixed the cam grooved pulley . The rod e¹
and guides e are traversed by means of a sliding bar k which at one end carries a
bowl working in the cam groove of the pulley i and at the other end is connected to
the rod e¹.
The above described arrangement gives a constant and uniform length of traverse
for the guides e and as a result bobbins with straight or parallel ends are wound
as shown.
Each bobbin is supported in a swinging bobbin lover which is pivoted at m¹ to
a bracket m to which is also pivoted the catch lever n. When the weighted catch n'
is released the parts fall into the relative positions indicated on Fig. 3 and the
bobbin is withdrawn from its driving drum as shown. It is obvious however that
the bobbins might be supported in any convenient manner so long as the catch levers
when released would withdraw said bobbins from contact with their driving drums.
We employ the usual arrangements for taking the lights away from the yarn
when a catch lever is released and a bobbin withdrawn from its driving drum g.
Again instead of the mechanism herein shown and described any suitable arrange-
ment of mechanism might be employed to impart the reciprocating motion to the
traversing guides e.
Figs. 7, 8 and 9 illustrate one arrangement by which we are enabled to impart
a variable length of traverse to the guides e so as to build bobbins with conical
or taper ends instead of with straight ends.

q
r"
In this arrangement the bracket is bolted lower down so that the spur wheel g
gears into the under side of the pinion g' instead of on the upper side as shown in
Fig. 2. The sliding bark is dispensed with and instead the rod e¹ is connected to a
box slide which is free to slide on horizontal roils 3 secured to the bracket j; a
nut o, mounted on a differential or other screw p, has a pin or projection which is
loose in a block fitted in a vertical slide formed in the horizontal box slide e² and
the nut o can be raised and lowered by turning the screw p. This scrow p is carried
pivoted lever
which is fulcrumed at to a bracket and is rocked by a bowl q
working in the cam groove of the revolving pulley i so that as the lever and nut o
rock, the part slides horizontally on the rods whereby the rod e' is actuated and
the guides e are traversed. By turning tho handle p' and operating the screw p the
nut o may be raised or lowered at will so as to give more or less movement to the
rod and guides e or the nut o may be automatically operated by means of a ratchet
wheels which is fixed on the screw and which is driven a tooth or teeth at each
oscillation of the rocking levery by pawls carried on a levert which is mounted
loosely on the screw p and comes against and is moved by an adjustable stop u.
The effect of thus operating the screw p is to automatically and gradually reduce
the length of the traverse of the rod e¹ and the guides e thereon and so cause the
bobbins to be wound with taper or conical ends. The extent of the reduction at each
oscillation of the lever q can be regulated by adjusting the stop u.
Yarn wound on tubes or bobbins without heals or flanges in the manner described
can be recled more quickly in the reeling machine than that wound on bobbins with
heads or flanges as now customary since the flangeless bobbins or tubes can be held
stationary and the yarn wound thereon will run freely off such flangeless bobbins or
tubes whereby the drag caused by the yarn having to pull flanged bobbins round on
their spindles is avoided.

page_text: 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-
1. The arrangement use and application of a series of quick traversing guides each
of which is placed close to the nip of its respective bobbin and drum substantially as and
for the purposes herein set forth.
2. The arrangement of mechanism herein shown and described or any equivalent
arrangement for imparting a variable length of traverse to a series of guides for the
purposes set forth.
3. The constructions and combined arrangements of parts embodying our improve-
ments in or relating to frames for gassing yarns substantially as and for the purposes
herein described and as illustrated by the Drawings annexed.
