Improvements in Self-acting Mules and Twiners.
We, JOSEPH TOOTELL, of 216, Tonge Moor Road, Mill Manager, and FRANCIS
EDWIN DAWSON, of 27, hent Street, Self-Actor Minder, both of Bolton, in the
County of Lancaster, do hereby declare the nature of our said invention to be as
follows:-
This invention relates to a new or improved self-locking roller motion for
roller-box employed in self-acting mules and twiners, and in apparatus connected
therewith, and consists in means to prevent slipping of roller-box, breaking of
wheels, dispensing with the use of springs hitherto employed, no cut or damaged
yarn through slipping out of gear, and wear and tear of the various parts will
be reduced to a minimum.
This we carry into effect by operating the roller-box by means of a pivoted
lever, one arm of which is actuated by the old or present roller-box rod according
to the movements of the mule carriage, by which action irregular stretching
of the yarn is prevented; and the apparatus may be put in and out of gear by
the attendant with the least possible exertion.

County of Lancaster, do hereby declare the nature of our said invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation of so much of a self-actor mule as is necessary to
illustrate our said invention Fig. 2 an end elevation of Fig. 1 looking from the
left hand side of the sheet of drawing, and Fig. 3 a plan on a reduced scale
showing the means for driving the bevel wheel C and spur wheel G on the front
roller shaft A.
In all the figures the same letters are employed to indicate corresponding parts.
A is the front roller shaft; 13 "roller-beam"; C bevel wheel driven by the
bevel wheel D and the usual gearing from the ordinary rim shaft of a self-actor
mule E front roller; F spur wheel for driving spur gear for operating the 1
usual back rollers (not shown); G spur wheel provided internally with the
serrated teeth I forming the "roller-box"; a rim pulley; b rim shaft; e loose
pulley; d fast pulley; e friction cone; f spur wheel on rim shaft; g spur wheel
on rim shaft; h spur carrier wheel; spur carrier wheel. k spur carrier wheel
on shaft. y is the clutch working in conjunction with the spur wheel m, and
7 shaft carrying bevel wheel 1) gearing into bevel wheel C provided on back
side with the serrated teeth H mounted on the front roller shaft A.
On the front roller shaft A is loosely mounted the bevel wheel C driven by
the bevel wheel D); the latter being located on the shaft actuated from the
ordinary rim shaft 6 by means of the spur wheels ghi and k. The back side of :
the bevel wheel C is provided with the serrated teeth H with which engages the
serrated teeth I on the face of the spur wheel G forming the "roller-box." The
spur wheel G is driven by the spur wheel m on the shaft rotated by the bevel
wheel gearing into the bevel wheel on the shaft 7.
This is the ordinary mechanism and no further description is therefore
necessary.
<<
According to my invention the spur wheel G with its serrated teeth I is put in
and out of gear with the serrated teeth H on the back of the bevel wheel C. by
means of the lever M pivoted to the "roller-beam" B by the pin or centre K.
The lever M is fitted with the roller N secured by the set screw 0%; the
roller N moving up and down in the slot P in the guide Q carrying the end of the
present roller-box" rod R by the to and fro sliding motions of the latter
according, to the movements of the mule carriage. The upper end of the
L pivoted lever M is provided with the fork Y located in the recess Z of the spur
wheel G, by which the serrated teeth I on the face of the spur
wheel G forming the
"
roller-box are moved in and out of action with the
serrated teeth H on the back side of the bevel wheel C. The fork Y is secured
to the upper end of the L lever M by the nut A. On the rod R is mounted the
bracket S secured by the set screw T. To the upper end of the bracket S on
the "roller-box" rod R is secured the stay W by the nut W₁; the other end of
the stay W coupling the bracket S to the arm V by means of the nut X to guide
and support the same in the fixing P¹. For the purpose of determining the
correct position of the lever M to ensure of the correct action of the serrated
teeth I on the face of the spur wheel G with the serrated teeth M we employ
the adjusting screw 02 mounted in the threaded boss 03 on the fixing P¹ secured
to the "roller-beam" B by the set screw P2. We would have it understood that
we do not confine ourselves to the precise details and configuration of the parts
we have shown and described as the same may be varied or modified without
departing from the principle of our said invention as they may be constructed and
arranged so as to meet the various kinds of self-acting mules and twiners.
employed.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is: -
The general arrangement construction and combination of parts composing our
improvements

of the spur wheel G, the L lever M being pivoted to the "roller-beam" B by the
pin or centre K: the opposite end of the lever M being fitted with the roller N
mounted in the slot P of the guide Q in which it is operated to place the serrated
teeth I in and out of gear with the serrated teeth H by the to and fro sliding
movements of the roller-box" rod R effected by the movements of the mule
carriage, together with the adjusting screw 02 mounted in the threaded boss 03
in the fixing P¹ for the purpose specified, the whole being connected applied and
operating substantially as described and as illustrated in the drawings.
