IMPROVEMENTS IN MACHINERY EMPLOYED IN PREPARING' WOOL, COTTON, AND OTHER FIBRES
Year: 1881

page_text: LETTERS PATENT to George Little, of Oldham, in the County of Lancaster,
Mechanical Engineer, for an Invention of "IMPROVEMENTS IN MACHINERY
EMPLOYED IN PREPARING' WOOL, COTTON, AND OTHER FIBRES."
PROVISIONAL SPECIFICATION left by the said George Little at the Office
of the Commissioners of Patents on the 5th November 1881.
GEORGE LITTLE, of Oldham, in the County of Lancaster, Mechanical Engineer.
"IMPROVEMENTS IN MACHINERY EMPLOYED IN PREPARING' WOOL, COTTON, AND
OTHER FIBRES."
This Invention relates to the "coilers" employed on machinery for purpose
aforesaid, and according to this Invention. The coiler box is caused at predetermined
intervals of time to move automatically from above one can to over or above the
adjoining can, that is to say, so soon as the coiler has delivered sufficient fibre to
fill the can thereunder, the coiler box or boxes will be selfactingly moved until
clear of the full can, and over or above an adjoining empty can which will be filled
in turn, and so on, in contradistinction to fixed and immovable coiler boxes and
moved or moving cans.
Suitable apparatus for automatically moving and changing the position of the
coiler box or boxes from can to can comprises catch pin, time gear wheels, levers,
and connections, holding catches, and friction motion operating gear connected by
loose collar on the upright shaft of coiler box, with a wheel moving the coiler box.
The time star or other like gear is such as to call into operation the mechanism for
moving and changing position of the coiler box or boxes at such intervals of time
as will permit the cans being filled, whereon the coiler box or boxes will move to
the next can, and so on, to any number of cans within the range of motion of the
coiler boxes. Where several coiler boxes are used, as in connection with a drawing
frame, the motion of coiler box from can to can will be lateral (or angular); in
such case the coiler boxes are mounted on a slide so as to move thereon from can
to can, the continuity of gearing being maintained by means of long keys or key
beds on or in the driving shaft carrying the driving pinions.
On the movement of the coiler box or boxes from filled to empty cans, a knife
or faller bar serves the sliver.

GEORGE LITTLE, of Oldham, in the County of Lancaster, Mechanical Engineer.
"IMPROVEMENTS IN MACHINERY EMPLOYED IN PREPARING' WOOL, COTTON, AND
OTHER FIBRES."
This Invention relates to the "coilers" employed on machinery for purpose
aforesaid, and according to this Invention the coiler box is caused at predetermined
intervals of time to move automatically from above one can to over or above the
adjoining can, that is to say, so soon as the coiler has delivered sufficient fibre to
fill the can thereunder, the coiler box or boxes will be self actingly moved until
clear of the full can, and over or above an adjoining empty can which will be
filled in turn, and so on, in contradistinction to fixed and immovable coiler boxes
and moved or moving cams.
Suitable apparatus for automatically moving and changing the position of the
coiler box or boxes from can to can comprises catch pin, time gear wheels, levers,
and connections, holding catches, and friction motion operating gear connected by
loose collar on the upright shaft of coiler box, with a wheel moving the coiler box.
The time-star-or-other-like-gear-is-such-as-to-call-into-operation the mechanism
for moving and changing position of the coiler box or boxes at such intervals of
time as will permit the cams to be filled, whereon the coiler box or boxes will
move to the next can, and so on, to any number of cans within the range of motion
of the coiler boxes. Where several coiler boxes are used, as in connection with a
drawing frame, the motion of coiler box from can to can will be lateral (or
angular); in such cases the coiler boxes are mounted on a slide so as to move
thereon from can to can, the continuity of gearing being maintained by means of
long keys or key beds on or in the driving shaft carrying the driving pinions. On
the movement of the coiler box or boxes from filled to empty cans, a knife comb
or faller bar serves the sliver.

Such being the nature and object of this my said Invention, I will now proceed
to describe the same in detail; and in order that the Invention may be fully
understood I have hereunto annexed 3 Sheets of Drawings illustrative thereof.

page_text: comb or knife 17 for severing the sliver when the feeding box is being moved or
passing from one can to another; and it will be seen the wheel S¹ by its partial
rotation in opposite directions gives reciprocating motion (likewise in opposite
directions) to the coiler box 13 and to the comb 17, so that when moved the
box and comb cross each other and effect the certain severance of the sliver, seo
Fig. 3.
The apparatus for measuring quantity of sliver or fibre to fill each can, and for
timing and determining when the radial or sliding movement of the coiler box or
boxes from full to empty can shall take place is illustrated in the several Figures of
annexed Drawings, and the principal parts thereof are numbered from 18 to 30
inclusive, such apparatus being similar to the measuring apparatus applied to gill
boxes, drawing frames, roving frames, and other like machines, and forms no part
of this Invention, being introduced here as suitable apparatus for timing and
measuring quantity of sliver or fibre for given size or internal capacity of can
or cans.
When applying the said Invention to drawing frames and other machines having
several coiler boxes, the several coiler boxes are connected by rod 31, and the
coiler boxes are changed from can to can on V slide bed 40 by means of arm 6
actuating the rocking bar 33 on its fulcrum pin 34. The upper end of 33 is
attached to link 35, the latter being secured to the coiler box 13 which is caused
to slide from full to empty can by means of precisely similar parts (to 1, 2, 3, 4, 5),
shewn in connection with the radial movement of the coiler box of Fig. 1 and 2,
Sheets 1 and 2.
Fig. 4 illustrates the coiler box in central position. The shaft 34 for driving
the coiler rollers is provided with a key which works in slot cut in boss of the
bevel wheel 35, so as to permit the shaft 36 to slide through the boss of bevel
wheel 35 during the reciprocation of the said shaft from side to side to position,
as shewn by dotted lines at 36, 37.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be or may be performed or
carried into practical effect, I would have it understood that I do not confine
the Invention to the use of the special apparatus by means of which the coiler box
or boxes is or are moved, as it is obvious various modifications of apparatus may
be employed for effecting the purpose desired, what I do claim is,—
The combination of movable coiler box or boxes having radial or sliding motion
(from can to can) imparted thereto, for the purpose herein described and substantially
as illustrated.
In witness whereof, I, the said George Little, have hereunto set my hand
and seal, this Twenty ninth day of April, in the year of our Lord One
thousand eight hundred and eighty two.
GEORGE LITTLE. (L.S.)
