page_text: 1, JAMES WHITEHEAD of 15 Rushcroft Road, High Crompton, Shaw near Oldham,
in the County of Lancashire, Mulo Overlooker, do hereby declare the, nature of this
invention to be as follows:―
This invention relates to improvements in self-acting mules and has for its object to.
improve the snarling motion, whereby the same will be more certain in its action,
work automatically without the attention of the minder, and the yarn is kept even and
free from snarls during doffing besides causing a cop of a given size to hold about.
10% more yarn than heretofore has been the case.
My improvements consist principally in making the ordinary stud which receives
the strap, in connection with the clutch box on the front roller shaft and which is,
adjustable in the snarling motion bracket by means of a thumb nut, to work auto-
matically, by bringing the same into connection with the back copping plate.
To this end 1 form on or attach to the back copping plate an arm or lever, the free
end of which I form with an eye or hole. Through this hole I pass a cord or its
equivalent which I furnish near each side of the said bracket at a certain distanco
apart from each other, with a projection or stop.
One end of this cord is brought over a guide pulloy fixed near the back copping
plate, and passed jointly with the other end, to the back of the head-stock, and then to
the snarling motion bracket in such a manner as to leave a clear road for the mulo
carriage to move in.
This I effect by employing two guide pulleys near the foot and two guide pulleys
near the top of the back of the head-stock over which the cord ends are passed
separately.
The snarling motion bracket is furnished at the top and bottom respectively with a
guide pulley and the studs moving therein with two guide pulleys instead of a thumb
nut, one end of the said cords being passed over the top and underneath round one of
the guide pulleys on the said movable stud, and then back to near the top guide pulley
where it is fastened on the said snarling motion bracket.

page_text: The other end of the said cord is passed underneath and round the bottom and over
the second of the guide pulleys on the said movable stud and then back to near the
-bottom-guide pulley, where it is suitably-fastened to the snarling motion bracket.

I, JAMES WHITEHEAD, of 15 Rushcroft Road High Crompton, Shaw near Oldham,
in the County of Lancashire Mule Overlooker, 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 improvements in self-acting mules and has for its object to
improve the snarling motion, whereby the same will be more certain in its action,
work automatically without the attention of the minder, & the yarn is kept even and
free from snarls during doffing, besides causing a cop of a given size to hold about
10% more yarn than heretofore has been the case.
My improvements consist principally in making the ordinary stud which receives
the strap, in connection with the clutch box on the front roller shaft, and which is
adjustable in the snarling motion brackot by means of a thumb-nut, to work auto-
matically, by bringing the same into connection with the back copping plate.
And in order that this invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference, indicating
like parts in the various figures.
Fig. 1 is a side elevation & Fig. 2 a front elevation of a portion of the headstock
of the mule with my improvements applied.
Fig. 3 is a detached plan of the back copping plate, and Fig. 4 a detached view of
the snarling bracket.
A is the back portion of the head-stock.
B the carriage. C the back copping
plate. D the clutch box on the front roller shaft. E the snarling motion or slide
bracket.
In carrying out my invention I form on or attach to the back copping plate C,
an arm or lever a, the free end of which I form with an eye or hole b. Through this
hole I pass a cord or its equivalent which furnish near each side of the said
bracket, arm, or lever a, at a certain distance apart from each other, with a projection
or stop d & d¹.

page_text: The latter I preferably arrange by inserting into the cord c where it passes
through the eye 6 of the lever a, a piece of wire a', the ends of which are formed into
loops, the loop serving as a stop on one side of the lever a, and the collar d' provided
adjustably on the wire a', as a stop on the other side of the lever a, to regulate the
travel of the cord c at will.
One end of this cord c is brought over a guide pulley e see Figs. 1 & 2 fixed near
the back copping plate C on the cross rail, and passed jointly with the other end to
the back of the headstock, and then to the snarling motion bracket E in such a
manner as to leave a clear road for the mule carriage B to move in.
.
This I effect by employing two guide pulleys el near the foot and two guide
pulleys e near the top of the back of the headstock A, over which the ends of the
cord c are passed separately.
The snarling motion bracket E is furnished at the top and bottom respectively with
guide pulleys g& g', and a stud / moving therein, with two guide pulleys h' instead
of a thumb-nut, one end of the said cord c being passed over the top guide pulley
and underneath round the guide pulleys h¹, on the said movable stud h, and then back
to near the top guide pulley g, where it is suitably fastened on the said snarling motion
bracket E.
The other end of the said cord c is passed underneath and round the bottom guide
pulley g¹ and over the second guide pulleys on the said movable stud h, and then
back near to the bottom guide pulley 'g, where it is also suitably fastened to the
snarling motion bracket E."
The stud h, as usual, receives the strap i in connection with the clutch D, and is
actuated in the snarling bracket E automatically from the back copping plate C by
reason of the cord c whereby the action of the clutch box and the revolution of the.
front roller-are automatically regulated, and thus the yarn kept even and and free
from snarls during doffing.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that. what I
claim, is :-
:-
In self-acting mules, actuating the stud in the snarling bracket E antomatically
from the back copping plate C, by means of the cord c, and the lever or arm a, or
their equivalent, operated substantially as and for the purpose set forth.
