PROVISIONAL SPECIFICATION.
Improvements in Mechanism in Self-acting Mules for Pulling the
Fallers Down when Backing Off the Coils on the Spindles.
I, JAMES ROBERT WAIN of East Bank, Fallowfield, Manchester, in the
County of Lancaster, Mechanic, do hereby declare the nature of this invention to
be as follows:
--
This invention relates to adjustable mechanism that may be employed for pulling
the fallers down when backing off the coils on the spindles on self acting mules for
spinning and doubling.
The object of this invention is to dispense with the use of chains such as have
hitherto been used for backing off, and which were difficult of adjustment.
I attain this object by the means hereinafter described and as shown in the
accompanying sheet of drawings which represents a transverse sectional elevation
of part of a mule frame with my invention applied. In the drawing a is part of
the mule carriage.
I mount on the tin roller shaft ba disc d with a spiral worm e formed on or
attached thereto; I place a bowl within the groove g formed by the aforesaid
spiral worm e, and attach thereto a lever 1, the lower end of said lever being fitted
to and swivelling on a stud j carried by the bracket j', placed near the back of the
frame a.
I connect the upper or opposite end of the lever to one end of the bell crank
lever by means of the rods m and m¹ that are looped together at m².
I connect the opposite end of the aforesaid bell crank lever by means of the
rod n, to the free end of the lever p that is attached to the shaft 9 on which the
faller sickles v are fitted.
When the backing off click t drops in the ratchet s, the spiral worm e is carried
round and the levers and rods herein before described pull the faller sickles v down
the distance that may be required.
By these means the faller wire will follow the coils on the spindles with
greater accuracy, fewer ends will be broken, and improved cop noses will be
formed.
The herein before described mechanism may be perfectly adjusted by means of
the screwed ends of the rods m¹ and n, and the slots and h¹.
Dated this 19th day of August 1893.

Improvements in Mechanism in Self-acting Mules for Pulling the
Fallers Down when Backing Off the Coils on the Spindles.
I, JAMES ROBERT WAIN, of East Bank, Fallowfield, Manchester, in the
County of Lancaster, Mechanic, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to adjustable mechanism that may be employed for pulling

page_text: the fallers down when backing off the coils on the spindles on self acting mules for
spinning and doubling.
The object of this invention is to dispense with the use of chains such as have
hitherto been used for backing off, said chains when adjusted requiring constant
supervision to keep them in order.
I attain this object by the means hereinafter described and as shown in the
accompanying two sheets of drawings, in which
Fig. 1 represents a transverse sectional elevation of part of a mule frame with
my invention applied; Fig. 2 is a front view and Fig. 3 a plan of the same;.
Figs. 4 and 5 are a plan and edge view respectively of a spiral worm or snail
forming the chief feature of my invention drawn to an enlarged scale.
In the several views shown on the drawings, similar letters refer to similar
parts.
In the drawings, a is part of the mule carriage: I mount on the shaft b which
carries the tin roller, a disc d with a spiral worm or snail e formed on or attached
thereto; I place a bowl f within the groove g formed in the aforesaid snail e, and
attach thereto a lever h, the lower end of said lever being fitted to and swivelling
on a stud j carried by a bracket as j¹ placed near the back of the frame a.
I connect the upper or opposite end of the lever h to one end of the bell crank
lever by means of the rods m and m' that are looped together at m².
I connect the opposite end of the aforesaid bell crank lever by means of the
rod n, to the free end of the lever p that is attached to the shaft q on which the
faller sickles v are fitted: When the backing off click t drops into the teeth of
the ratchet wheels, the spiral worm or snail e is carried round and the levers and
rods herein before described pull the faller sickles v down the distance that may be
required.
By these means the faller wire will follow the coils on the spindles with
greater accuracy, fewer ends will be broken, and improved cop noses will be
formed.
The herein before described mechanism may be perfectly adjusted by means of
the screwed ends of the rods m³ and n, and the slots and h³.
Having. now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. In self acting mules that are employed for spinning and doubling, the use
of a snail as e in lieu of chains for operating the faller sickles, substantially as
herein before described.
2nd. In self acting mules that are employed for spinning and doubling, the use
of a snail as e in combination with the several rods and levers for actuating the
shaft on which the faller sickles are fitted, for the purpose and in the manner
substantially as herein before described.
3rd. In self acting mules that are employed for spinning and doubling, the
mechanism for operating the faller sickles, substantially as herein before described
and as shown on the drawings.
