page_text: I HIRAM JAGGER 74 Ryan St. Manchester Rd. Bradford Spinning Manager do
hereby declare the nature of the said invention for RING OR CAP SPINNING to be
as follows:
Ring or Cap Spinning suffers a loss of production, having much more tension on
the Thread at the beginning of the Bobbin than at the end when full. The Rollers
rum much slower to suit this condition: my Invention is increasing the speed
of the said Rollers as the Bobbin fills. Stopping at any stage or at the End
when full.
This I do by means of Cones or any other means produceing Differential Motion
on the said Rollers for the purpose of increased production or character of
Thread. The increased Speed of the Spinning Machine applies to the Roller
portion only.
This I do by means of 2 cones (3 ft in length, diameter of each cone tapered
from 12 in to 102 ins) placed parallel to each other, the small part of the one cone
opposite the thick part of the other. A strap is placed on them and worked by a
mechanical stop motion during a required time.
This differential motion is connected to the rollers of the spinning machine by.
means of straps or gearing as at present.

page_text: I HIRAM JAGGER of 74 Ryan Street, Manchester Road, Bradford, in the County
of York, Spinning Manager do hereby declare the nature of the said invention
for "IMPROVEMENTS IN RING OR CAP SPINNING MACHINERY" and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement, aided by the annexed drawings:—
This invention consists of improved apparatus whereby a differential motion is
imparted to the delivery rollers so as to adapt the speed of such rollers to the
changing diameter of the bobbin or spool and thus regulate the drag on the yarn-
also to operate the mechanism so that the rotation of the bobbin ring traveller or
flyer shall be continued a little after the rotation of the delivery rollers cease,
whereby additional twist will be put into the length of yarn between the delivery.
rollers and the bobbin or spool, this harder twist yarn being enabled to withstand
greater tensile strain so that on the frame being re-started the liability to breakage
or "ends down" is obviated and to a mechanical or automatic stop motion.
Such being the nature and object of the said invention the following is a
complete description of same reference being had to the accompanying drawings
forming a part of this specification in which:
Fig. 1 is an end elevation of spinning frame having my improvements applied
thereto.
Fig. 2 is a side elevation of the same.
Fig. 3 is an enlarged view of part of the apparatus.
Fig. 4 is detail of strap controlling apparatus.
Fig. 5 is a plan of Fig. 4.
On the main driving shaft 1 of the frame is a pulley 2 which drives by means
of strap 3 pulley 4 secured to shaft 5 on which is cone 6 the latter by strap 7
drives the cone 8 on the shaft of which is a friction pulley 9 held by spring and
nut 10 against the end of cone 8 on the cone shaft 11 is a pulley 12 which drives
by means of strap 13 the pulley 14 on stud 15, on the latter is the wheel 16 gearing
with the intermediate wheel 17 which drives the wheel 18 on the drawing roller
shaft 19. 20 are the drawing rollers. At the other end of the shaft 19 is a band
pulley 21 which by means of band 22 pulley 23 on stud 24 which also carries
pinion 25 gearing with wheel 26 on end of screw 27 by which the said screw is
caused to rotate in the nut 28 and gradually draw the rod 29 and fork 30 thereon,
and traverse the strap 7 from the larger to smaller end of cone 8 thereby varying
the speed of the intervening gear and drawing rollers 20 whereon the pin 31
of the nut 28 reaches the end of its slot 32 in rod 33 the end 34 of the latter is
thus pressed against the lever 35 which it knocks off or forces out of its holding
notch 36 whereon the weighted lever 35 moves or lowers on its fulcrum pin 37
thereby lowering the pinion 25 out of gear with the wheel 26 and the traverse
of the strap fork 30 is arrested the frame then continues to run at an uniform
speed until the "minder" or operator reverses the motion of the screw 27 by
means of the handle 39 transferring the strap 7 to the friction pulley 9, and by
means of the rack 40 pinion 41 and rack 42 on strap fork rod 43 the strap 44 is
transferred from the fast pulley 45 to the loose pulley 46 and the frame is stopped-
It will be seen that the strap 7 reaches its friction pulley 9 a little before the main
driving strap 44 reaches its loose pulley 46, so that the drawing rollers operated
from the cone 8 cease to rotate a little time before the motion of the bobbins is
arrested, the latter being driven from the pulley 45 and thus there is a continuance

page_text: of the twisting for a short period after the motion of the drawing rollers is arrested
whereby the portion of yarn between the bobbin and drawing rollers receives
additional twist and is thereby made stronger and better adapted to withstand the
strain or tension thereon when the frame is again started after doffing that the
extra twisted and consequently stronger length of yarn admits of the use of
smaller barrelled bobbins so that a greater quantity of yarn can be wound upon
a bobbin of given size of flange.
It will be obvious that instead of the cone drums friction plate and friction
pulley could be used so as to obtain the differential motion but I prefer the cones.
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:
The combination of the cones, and the rods, screw and wheel gear, whereby the
strap is traversed along the cone together with the adjustable automatic stopping
apparatus for the purpose and as herein described.
