Improvements in Machines employed in the Preparation of Fibrous
Materials for Spinning.
I, WILLIAM HENRY RHODES, of 5, Lime Grove, Longsight, Manchester, in the
County of Lancaster, Machinist, do hereby declare the nature of this invention
to be as follows:-
My invention relates to improvements in machines employed in the preparation
of fibrous materials for spinning and the chief object of my improvements is to
dispense with the usual differential or building motion as well as spindles and
flyers driven by skew gearing and generally to simplify the ordinary roving
frame.
In carrying my invention into effect mount the slubbing bobbins in the
ordinary manner and use drawing rollers as in an ordinary roving frame. The
winding on bobbins have flanges and are driven by frictional contact with
rotating drums upon which they are supported. Each roving from the drawing
rollers is led into a tube carried by a bearing on the end of a rod pivoted to a
sliding bracket mounted upon a stationary shaft; this tube is preferably partly
cut away so as to expose the roving for convenience in piecing up but the extreme
end or bridge of the tube is hollow and is supported by an extension from its
main bearing; where the tube is cut away there are two drag pins or studs or
an equivalent tension device round which the roving is passed on its way to the
bridge of the tube which almost touches one of the driving drums on to which
the roving is delivered and passes from it to the winding on bobbin which rests
on the drum. In order to ease the passage of the roving on to the drum, I prefer
to employ a fluted or other presser roller which is carried in arms pivoted to the
frame so that the roller rests upon the roving on the drum close to where it comes
away from the tube.
The tubes are driven intermittently, say for example, they are driven whilst
five inches or other length of roving is wound on the bobbins and are stationary
whilst an equal length is wound on.
The roving might be fed directly on to the winding on bobbin, and in this case
I should employ the pivoted presser roller and as the bobbin of roving increases
in diameter the pivoted bearings would allow the tube and presser roller to move
away gradually.
A convenient mode of driving the tubes is as follows:-
I mount a grooved pulley on the main or other shaft of the machine and on this
pulley is a rope or band made say of two sizes; this band passes over special
grooved pulleys on shafts on each of which is a grooved pulley for driving by
a band a grooved pulley fixed on one of the tubes; these special pulleys consist
of three parts, two flanges fixed on the shaft to form a pulley for the large part
of the band, and a narrow pulley loose on the shaft between the pair of flanges
to receive the small portion of the band, consequently when the larger part of

page_text: the band is riding on the fixed flanges the shafts and the tubes are rotated but
when the smaller portion of the band. passes it rides on the small loose pulleys
and so the shafts and tubes remain stationary.
I propose also to weight these shafts so as to cause them to stop quickly when
the size of band changes, and further I arrange weights or equivalents to put
a separate tension on each band which drives a tube.
The tubes are traversed to lay the rovings evenly on the winding on bobbins
by any convenient traversing motion and to avoid checking the rotation of the
bobbins I mount an anti-friction bowl or bowls on the bearing of each tube.

Improvements in Machines employed in the Preparation of Fibrous
Materials for Spinning.
I, WILLIAM HENRY RHODES, of 5, Lime Grove, Longsight, Manchester, in the
County of Lancaster, Machinist, 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:-
My invention relates to improvements in machines employed in the preparation
of fibrous materials for spinning and the chief object of my improvements is to
dispense with the usual differential or building motion as well as spindles and
flyers driven by skew gearing and generally to simplify the ordinary roving frame.
In carrying my invention into effect I mount the slubbing bobbins in the
ordinary manner and use drawing rollers as in an ordinary roving frame. The
winding on bobbins have flanges and are driven by frictional contact with
rotating drums upon which they are supported. Each roving from the drawing
rollers is led into a tube carried by a bearing on the end of an arm pivoted to a
bracket mounted upon a traverse rail; this tube is preferably partly
cut away so as to expose the roving for convenience in piecing up but the extreme
end or bridge of the tube is hollow and is supported by an extension from its
main bearing where the tube is cut away there are two drag pins or studs or
an equivalent tension device round which the roving is passed on its way to the
bridge of the tube which almost touches one of the driving drums on to which
the roving is delivered and passes from it to the winding on bobbin which rests
on the drum. In order to ease the passage of the roving on to the drum and
to retain the twist put in by the rotating tube, I prefer to employ a fluted or
other presser roller which is carried in arms pivoted to the frame so that the
roller rests upon the roving on the drum close to where it comes away from the
tube.
The tubes are driven intermittently, say for example, they are driven whilst
five inches or other length of roving is wound on the bobbins and are stationary
whilst an equal length is wound on.
The tubes are traversed to lay the rovings evenly on the winding on bobbins
by any convenient traversing motion.
In the accompanying sheet of drawings-
Fig. 1 is an end sectional elevation and Fig. 2 part of a front view of a roving
frame made according to my invention. Fig. 3 is an end view showing part of

page_text: the driving mechanism. Fig. 4 is a detail view of a pair of driving drums and
a pair of flanged winding on bobbins, the latter shown filled. Fig. 5 is a view,
half full size, of part of Fig. 1. Figs. 6, 7, 8, 9 10 and 11 are parts of the
machine, full size, and Fig. 12 is a view of a piece of a round driving band formed
of two diameters, employed to rotate the tubes which put twist into the slubbing.
In the drawings,-1 denotes the frame of the machine, 2 the drawing rollers,
3 the driving drums, 4 the flanged winding on bobbins, 6 the tubes through
which the slubbings pass from the drawing rollers to the winding on bobbins,
7 the cam and connections for giving the requisite traverse to a traversing rail 8
which is mounted upon antifriction rollers 9. To the rail 8 are secured a number
of brackets 10 each of which carries a stud 11 and upon each stud is pivoted an
arm 12 in the upper part of which are formed bearings for two of the tubes 6;
to each arm 12 is pivoted a lever 13 which carries at one end a fluted presser
roller 14 and at the other a pulley 15 over which passes a cord fastened to the
arm 12 and carrying a weight 16. On the driving shaft 17 of the machine is
mounted a grooved pulley 18 which drives intermittently the tubes 6 by means
of a band 19, see Fig. 12, made of two diameters, which passes over guide pul-
leys 20 and special grooved pulleys mounted upon shafts 21. Each special pulley
is made of three parts, a pair of flanges 22 secured upon the shaft 21 and a small
pulley 23 placed between the flanges 22 and loose upon the shaft; each of the
shafts 21 is pivoted at one end to a bracket 24 secured on a transverse rail 25
and the front end of the shaft is mounted in a bearing carried in a slide which
can be drawn down by a weight 26 in order to put tension on a band 28 which
passes from a two grooved pulley 27 round two pulleys 39 mounted respectively
on two of the tubes 6. Each slubbing from the drawing rollers is led into one
of the tubes 6 which is preferably cut away near one end so as to expose the slub-
bing but the extreme end or bridge of the tube 6 is hollow at 30 and where the
tube is cut away there are two drag pins 29 or studs or any equivalent tension
device.
In operation, the bobbins of slubbings, which are not shown, are mounted as
usual upon the roving frame and the slubbings 31 pass through the drawing
rollers 2 and thence are threaded through the tubes 6, the front ends of which
are drawn against the driving drums 3 by the weights 16. When the machine
is in motion, the band 19 from the pulley 18 on the driving shaft gives an inter-
mittent motion to the tubes 6 say for example, the tubes are rotated whilst five
inches or other length of roving is wound on the bobbins and are stationary
whilst an equal length is wound on, and the operation is continued until the
bobbins 4 are filled with roving as shown. Each bobbin has two separate cheeses
wound upon it and the bobbin which is flanged at each end, is driven by the
frictional contact of the wound on roving and the driving drums 3. The twist
put into the slubbing by the rotation of the tubes 6 is retained by the weighted
presser rollers 14 or by any other suitable device.
Although I prefer to feed the slubbings 31 on to the driving drums they might
be fed directly from the tubes 6 on to the winding on bobbins 4, and in this case
I should also employ the presser rollers 14 and as the bobbins of rovings increased
in diameter the pivoted arms 12 would yield and allow the tubes and presser
rollers to move back gradually.
In each case the pivoted arms 12 upon which the tubes 6 are carried are tra-
versed by connections from the cam to the rail 8 to cause the tubes to lay the
rovings evenly on the winding on bobbins.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what
I claim is:
1. A tube capable of being rotated intermittently for the
ALBAL L
purpose
of putting

page_text: slubbing as roving on to a driving drum and thence to a winding on bobbin or,
directly to the winding on bobbin in combination with a weighted presser roller
or equivalent device for retaining the twist put into the slubbing by the rotation
of the tube substantially as herein set forth.
2. The combination with a tube capable of being intermittently rotated for the
purpose of putting twist into the slubbing passed through it, of a driven band of
two diameters and special pulleys one fast and one loose for imparting the inter-
mittent rotation to the tube substantially as herein set forth.
3 In combination, the drawing rollers, driving drums winding on bobbins,
twisting tubes, weighted presser rollers and means for rotating intermittently
and traversing the twisting tubes all substantially as herein set forth.
