I FERDINAND ROSSKOTHEN at present residing at Avenue Parade Accrington
in the County of Lancaster, Engineer do hereby declare the nature of the said
invention for "AN IMPROVEMENT IN ROVING INTERMEDIATE AND SLUBBING
FRAMES" to be as follows :-
My invention relates to the arrangements for imparting motion to the flyers and
the tubes or bobbins of roving intermediate and slubbing frames and has for its
objects to render such frames capable of producing right or left hand rovings with
the same flyers and to cause either the flyer or the tube to lead as desired.
I transmit motion to the cone shaft through intermediate wheels which are carried
by a lever or carrier which is mounted upon the cone shaft or upon the same.axis.
When one intermediate wheel is used the cone shaft and the driving shaft run in
the same direction. When desired a second intermediate wheel is added and the
direction of revolution of the driving shaft is then reversed the cone shaft continuing
to revolve in the same direction. By these means the direction of revolution of the
spindles and tubes is reversed. This reversal of the motion of the driving shaft
has the effect of reversing the direction of revolution of the flyers and tubes and
also of changing the lead so that if the flyers had led before the reversal the tubes
or bobbins will lead after reversal or the leading of the tubes will be changed to
the leading of the flyers according to circumstances the same flyers being used as
before the reversal. I do not confine myself to the precise details of the reversing
motion.

My Invention relates to the arrangements for imparting motion to the flyers and
the tubes or bobbins of roving, intermediate and slubbing frames and has for its
objects to render such frames capable of producing right or left hand rovings with
the same flyers and to cause either the Byer or the tube to lead as desired.
I transmit motion to the cone shaft through intermediate wheels which are carried
by a lever or carrier which is mounted upon the cone shaft or upon the same axis.
When one intermediate wheel is used the cone shaft and the driving shaft run in
the same direction When desired a second intermediate wheel is added and the
direction of revolution of the driving shaft is then reversed the cone shaft continuing
to revolve in the same direction. By these means the direction of revolution of
the spindles and tubes is reversed. This reversal of the motion of the driving
shaft has the effect of reversing the direction of revolution of the flyers and tubes
and also of changing the lead so that if the flyers bad led before the reversal the
tubes or bobbins will lead after reversal or the leading of the tubes will be changed
to the leading of the flyers according to circumstances the same flyers being used
as before the reversal. I do not confine myself to the precise details of the
reversing motion.
And in order that my said invention may be properly understood I will now
proceed more particularly to describe the same reference being had to the annexed
sheet of drawings and to the letters and figures marked thereon. Figs: 1. 2. 3.
and 4. show the different arrangements of flyer and bobbin necessary under present
arrangements and which I propose to simplify by means of my invention. In
Figs 1 and 2 the direction of revolution is to the right in Figa: 3 and 4. to the
left. In Figs. 1 and 4. the bobbin leads; in Figs 2 and 3 the flyer leads. By
means of my invention either a right or left hand rotation can be obtained in any
of the forms shewn without changing the flyers and either the spools or the flyers
can be made to lead. Thus in the case of a frame furnished with leading flyers
and rotating to the right as shewn in Fig: 2. I may cause the spools to rotate to
the left and to lead as in Fig: 4. or otherwise if a frame has flyers which lead,
rotating to the left as in Fig: 3. I reverse the rotation to the right as in Fig: 1.
in which case the spools or bobbins would lead. This is effected by reversing the
direction of rotation of the main shaft of the frame, but to enable the direction
of revolution of the upper cone shaft to remain constant I apply one or more
intermediate driving wheels between the said main shaft and the cone shaft Fig: 5
shows a portion of the driving arrangement of a frame from which it will be seen
that the drawing rollers always retain their proper direction of revolution as does
also the differential gear marked d. The main shaft a when reversed drives the
spools quicker or slower according to the speeds from which the change was made.
The means for connecting the main shaft a. and upper cone shaft b. are shewn at
Figs: 6. 7. and 8 of the drawings. A lever c is pivoted on the cone shaft b. and
carries one or both of the intermediate wheels, m, n. a handle being formed at the
lower end of the said lever. As the lever is centred on the cone shaft b. the first
intermediate wheel always remains in gear with the wheel l. on the cone shaft and
by moving the lever the same intermediate wheel or an additional wheel can be
i.

placed in gear with the spur pinion 3. on the main shaft a. In Figs 7 and 8 two
such intermediate wheels m and n are shewn. If only one intermediate wheel is
required, the wheel n is removed and the wheel m is brought into contact with
both of the wheels and < The shape of the lever and the dimensions of the
intermediate gearing are so arranged as that the spur pinion on the main shaft
can engage with only one of the intermediate wheels at a time. The bolts is
provided to bind the lever in position to the framing of the machine.
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:
1. In slubbing, roving and intermediate frames the means whereby the direction
of revolution and the lead of the bobbins and flyers can be changed without
altering the direction of revolution of the cone shaft b. and parts driven therefrom
substantially as described and shewn.
2. The arrangements of apparatus shown in Figs: 6 to 8 substantially as and for
the purpose described and indicated.
