PROVISIONAL SPECIFICATION left by John Ashton at. the Office of

1855.
I, JOHN ASHTON, of Oldham, Lancashire, do hereby declare the nature of
the said Invention. of "IMPROVEMENTS IN CERTAIN PARTS OF MACHINERY KNOWN
AS SELF-ACTORS (EMPLOYED FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS
MATERIALS), FOR MORE EFFECTUALLY CROSSING THE YARN DURING THE SHAPING OR
BUILDING OF THE 'COPS' THAN HERETOFORE," to be as follows:-
These improvements consist principally in the use and employment of a
scroll of novel and improved construction in lieu of the drum usually
employed in self-actors for regulating the motion or speed of the spindles,
and thereby to adapt the speed thereof to the undulatory or up and down
motion of the "faller" during the running in of the carriage. The nature of
these improvements will, however, be better understood by the following
description thereof:-
And I would first remark that in self-actors of the ordinary construction
the drum on the back shaft in the headstock, being connected with the
carriage, always revolves at a fixed relative speed to that of the carriage in
running in or out. A band is also employed for connecting the drum on the
back shaft with another similar drum on the front shaft in the headstock, on

page_text: which shaft is fixed the pinion which imparts motion to the quadrant. On
the arm of the quadrant there is a worm capable of revolving on its own
centre by means of a handle placed on the end thereof. On this worm is a
moveable nut, to which is attached one end of a chain, the other end of said
chain being attached to the drum inside the carriage for giving motion to the
spindles as the chain is pulled off the drum by the going in of the carriage,
during which time the quadrant moves on its centre towards the carriage, and
thus gives to the spindle a gradual and continually increasing speed as the
carriage is going in; and thus performs one movement only of the faller from
the bottom to the top of the cop. Now, the improvements which constitute
this Invention consist,―
Firstly, in giving to the "faller "three movements during the running in of
the carriage, by forming the upper edge of the copping rail with three inclined
planes, the faller being connected therewith in the usual way; thus as the
carriage runs in, the faller is raised by the first incline, lowered by the second
incline, and again raised by the third incline.
The second part of these improvements consists in giving to the quadrant
and spindles a varying speed, corresponding to the varying movements of the
faller," by the use of a scroll constructed with a varying radius; that is to
say, I form the scroll with a right and left handed spiral-shaped groove or
channel, the spiral being so formed or disposed as that the periphery of the
groove is spirally eccentric to the axis of the scroll.
