Machinist, for the Invention of "IMPROVEMENTS IN SELF-ACTING MULES FOR
SPINNING AND DOUBLING."
the 23rd February 1877, and dated the 15th September 1876
PROVISIONAL SPECIFICATION left by the said John Wain at the Office of the
Commissioners of Patents on the 15th September 1876.

MENTS IN SELF-ACTING MULES FOR SPINNING AND DOUBLING."
"IMPROVE-
My Invention consists in an improved combination and arrangement of parts for
putting up or running in the carriage of a self-acting mule, being an improvement
upon the machinery described in the Specifications of Letters Patent granted to
Robert Lakin and William Henry Rhodes, on the 12th day of October, 1849,
No. 12805, and to George Park Macindoe, on the 2nd day of November 1849,
No. 12822. In the former the carriage was put up by levers, wheels, and racks
placed horizontally near the floor, and in the latter a vertical lever is shewn acting
on the carriage, and a horizontal lever is referred to.
My Invention consists in putting up or running in the carriage by means of a
horizontal lever vibrating on a stud fixed to the floor, which lever is caused to
vibrate by a link hinged to a crank pin in a wheel driven by a pinion on the
ordinary friction or catch box shaft; the link fits on an adjustable stud in the
lever, and the outer end of the lever is connected to the carriage by an antifriction
bowl running between two guide bars. When the carriage is up the end of the
link comes against a disc at the under side of the friction box to prevent the over
running of the carriage.
My Invention may be modified by the use of two vibrating levers coupled by
toothed segments; by this arrangement the carriage is acted upon at two points,
thereby distributing the power required for moving it.

JOHN WAIN, of Manchester, in the County of Lancaster, Machinist. "IMPROVE-
MENTS IN SELF-ACTING MULES FOR SPINNING AND DOUBLING."
My Invention consists in an improved combination and arrangement of parts for
putting up or running in the carriage of a self-acting mule, being an improvement
upon the machinery described in the Specifications of Letters Patent granted to
Robert Lakin and William Heury Rhodes,. on the 12th day of October, 1849,
number 12805, and to George Park Macindoe, on the 2nd day of November, 1849,
number 12822. In the former the carriage was put up by levers, wheels, and racks
placed horizontally near the floor, and in the latter a vertical lever is shewn acting
on the carriage, and a horizontal lever is referred to.
My Invention consists in putting up or running in the carriage by means of a
horizontal lever vibrating on a stud fixed to the floor, which lever is caused to
vibrate by a link hinged to a crank pin in a wheel driven by a pinion on the
ordinary friction or catch box shaft; the link fits on an adjustable stud in the lever,
and the outer end of the lever is connected to the carriage by an antifriction bowl
running between two guide bars.
My Invention may be modified by the use of two vibrating levers coupled by
toothed segments, by this arrangement the carriage is acted upon at two points,
thereby distributing the power required for moving it.
And in order that my Invention may be fully understood and readily carried into
operation I will proceed to describe the accompanying Sheet of Drawings, reference
being had to the figures and letters marked thereon.
Fig. 1 is an elevation; and Fig. 2, a plan of part of a self-acting mule of the
ordinary construction to which my improvements are applied.
a is part of the carriage; b, the upright or catch box shaft; c, the catch or
friction box; and d, a spur pinion fixed on the lower half thereof; these and all the
other parts requisite to complete the machine, which are not described hereafter,
are made in any approved manner. The pinion d gears into the wheel e, which is
mounted on a stud fixed in the bottom plate f; to enable this wheel to be taken out
of the machine without disturbing the pinion d I form the wheel with a loose
segment e, to the bottom plate is also fixed the fulcrum stud g of the horizontal
lever l, which is caused to vibrate by the link i, one end of which is jointed to the
crauk pin e¹ in the wheel e, and the other to the adjustable stud h¹ in the lever h.
At the outer end of the lever h is the antifriction bowl h² which runs between the
guide bars j, j, fixed to the under side of the carriage a; these guide bars may either
be straight, as shewn in the Drawing, or they may be curved, as described in the
Specification of Letters Patent granted to Henry Baxter, Luke Rushworth, and
Heury Clough, on the 31st day of July, 1875, No. 2714. By moving the stud h¹ in
the lever hand varying the length of the link i, which is made in two parts con-
nected by bolts and a regulating screw, the traverse of the carriage can be varied.
The Drawing represents the parts in the positions they occupy when the carriage
is nearly out or about at the extremity of the stretch. When the backing off is
completed the two halves of the friction box c are put into contact in the usual
manner, and motion is communicated to the lower half and to the pinion d fixed
thereon and through it to the wheel e, which in revolving then acts on the link i
and causes the lever to put up the carriage at the speed required.
The carriage is taken out by scrolls on the back shaft and bands in the ordinary
manner. When the carriage is out it is held stationary during the backing off by
the spring lever m acting on the cam e² fixed to the wheel e or by any other
equivalent, this lever and cam also prevent the over running of the carriage and
wheel e, and may be used in lieu of the disc under the friction box referred to in
the Provisional Specification filed in applying for these Letters Patent.

page_text: In Fig. 2 I have shewn in dotted lines a modification of my Invention, whereby
the carriage is acted upon at two points so as to distribute the power required for
putting it up. To the lever his cast a toothed segment h³ gearing into a similar
segment fixed to the second lever h, at the end of which is a bowl h² fitting between
two bars j fixed to the carriage.
Having thus stated the nature of my Invention, and described the manner of
performing the same, I wish it to be understood that I do not claim the putting up
of the carriage by means of a lever, as this has been done by others, as before
referred to; but what I claim is, the improved combination and arrangement of the
parts for putting up the carriage, consisting of the crank pin e¹ in the wheel e, the
link i and the lever h vibrating on the fulcrum stud g, all as shewn and described.
I also claim applying the power for putting up the carriage at two points, as shewn
and described.
In witness whereof, I, the said John Wain, have hereto set my hand and seal;
this Ninth day of March, One thousand eight hundred and seventy-
seven..
