Improvements in Spinning Mules.
We, SAMUEL HERBERT BROOKS, and FREDERICK GEORGE GOODBEHERE, of the
Firm of Brooks & Doxey, of the Union Iron Works, West Gorton, Manchester, in the
County of Lancaster, Machine Makers (a communication from Frederick
Mackavoy, of Sagan-in-Schl, in the Empire of Germany, Spinning Overlooker,)
do hereby declare the nature of this invention to be as follows:-
This invention relates more particularly to mules for spinning wool and is
designed to provide a stop motion whereby the mule will be stopped when the
cops are full.
It consists essentially of a lever or catch pivoted on top of the carriage one end
of which is connected by a link or rod with the drag slide and the other end
engages with a spring controlled slide or block sliding over the stop rod which
when the pivoted lever releases it engagés with a collar on the stop rod causing it
to travel and stop the mule.
On the mule carriage preferably bolted to the faller stands is fitted a base plate
or bracket comprising a flat piece of iron provided with screws at both ends. To
this is attached by screws or bolts a box bracket or bracket of other convenient
shape carrying a pin or stud upon which is pivoted an oscillating or rocking lever
or catch. To one end of this lever is attached a connecting link or bar by which it
is connected with the regulating stud of the drag slide or to the drag slide itself.
The link or connecting bar is provided with suitable slots and bolts so that it may
be set or adjusted to the size of cops.
At the other end of the pivoted lever or catch is placed a sliding piece or block
which is capable of sliding to and fro in a groove or slot cut in the base plate.
It is preferably secured by a nut on a projecting screw but may slide in a dove-
tail groove or between other suitable guide. This sliding piece or block is also
provided with a hole through which the stop rod passes so that it can slide over
the stop rod or the stop rod be moved through it. A spring draws it in one
direction and it is moved back in the other direction by an adjustable collar fixed
on the stop rod. When drawn back against the pull or pressure of the spring it
engages with the end of the pivoted lever or catch by which it is held until the
end of the lever or catch is raised to release it. The end of the lever or catch is
held down by a spring of any suitable form. On the stop rod is placed a collar
or shoulder against which the slide comes in contact when released and moves
the stop rod to stop the mule.
In operation when the cops are full the drag slide operating through the con
necting link or bar draws down the free end of the pivoted lever or catch and
releases the slide at the other end. The slide is then drawn back by its spring
carrying or moving the stop rod along with it. The stop rod may be moved inde

page_text: pendently to stop the mule but when moved to start the mule carries the slide
back with it into engagement with the end of the lever, and thus sets it again.

improvements in Spinning Mules.
We, SAMUEL HERBERT BROOKS, and FREDERICK GEORGE GOODBEHERE, of the
Firm of Brooks & Doxey, of the Union Iron Works, West Gorton, Manchester, in the
County of Lancaster, Machine Makers (a communication to us from Frederick
Mackavoy, of Sagan-in-Schl, in the Empire of Germany, Spinning 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 more particularly to mules for spinning wool and is
designed to provide a stop motion whereby the mule will be stopped when the
cops are full.
It consists essentially of a lever or catch pivoted on top of the carriage, one end
of which is connected by a link or rod with the drag slide and the other end
engages with a spring controlled slide or block sliding over the stop rod which
when the pivoted lever releases it engages with a collar on the stop rod causing it
to travel and stop the mule.
It will be fully described with reference to the accompanying drawings in which
sufficient parts of the machine are shown to illustrate the invention.
Fig. 1. Elevation.
Fig. 2. Plan.
Fig. 3. Elevation showing connection with drag slide.
Fig. 4. Plan of Fig. 3.
To the faller stand or other part of the mule carriage we fit a base plate or
bracket A of flat or other suitable shape with screws a at both ends. On the base
plate A we bolt or otherwise rigidly affix a box bracket B or bracket of other suit-
able shape with a stud or pin 6 secured at one side and upon this stud b is pivoted
an oscillating or rocking lever or catch C. To one end of the lever C is attached
a connecting link or bar D by which it is connected with the regulating studs of
the drag slide S or to the drag slide S itself. The drag slide S is moved to and fro
in the bracket R affixed to the mule carriage M by the bowl r which traverses the
builder rail T in the usual way.
The link or connecting bar D) is provided with suitable slots d and bolts so that
it may be set or adjusted according to the size of cops.
The stop rod E is supported by or passes through the fixed bracket B being free
to move longitudinally.
Upon the base plate A. and at or near the free end of the rocking lever or catch C
is placed a sliding block or piece G capable of sliding to and fro thereon. It is
preferably secured by a screw g projecting through a slot c in the plate A with a
nut on the under side but it may be fitted to slide in a dovetail groove or between
other suitable guides. A spring H is arranged on the underside of the plate A.
one end being secured thereto and the other connected to the sliding block G to
draw the block in one direction.

The sliding block G is constructed with a hole or otherwise to embrace the stop
rod E so that while it may slide over the stop rod or the stop rod slide through it, 5

page_text: it can engage with a collar K on the stop rod and carry the rod along with it.
The spring H draws the sliding block G in one direction and it is moved back or
in the opposite direction by the adjustable collar K on the stop rod E when the rod
is moved.
When the block G is moved back against the pull or pressure of the spring H
it engages with the end of the pivoted lever or catch C and is thereby held until
the end of the lever or catch is raised to release it. The end of the lever or catch C
is held down by a spring L of any suitable form. The slide block G when released
by the raising of the catch lever C engages with the collar K on the stop rod E
and moves the rod to stop the mule.
In operation when the cops are full the drag slide S operating through the
connecting link or bar D draws down the free end of the pivoted lever or catch C
and releases the slide G at the other end. The slide is then drawn back by its
spring H carrying or moving the stop rod E along with it. The stop rod may be
moved independently to stop the mule but when moved to start the mule carries
the slide G back with it into engagement with the end of the lever C and thus sets
it again.
Having now particularly .described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what we
claim is:
1. A stop motion for mules by which the mule will be stopped when the cops
are full constructed with a lever or catch pivoted on the top of the carriage one end
of which is connected to and operated by the drag slide and the other end engages
with a spring operated slide block engaging with a collar on the stop rod which
when released by the raising of the pivoted catch moves the stop rod to stop the
mule substantially as described.
2. A stop motion for mules by which the mule will be stopped when the cops
are full comprising a bracket or base plate attached to the mule carriage, a lever
or catch pivoted upon a bracket thereon connected with the drag slide, a sliding
block moved in one direction by a spring and held against the force of the spring
by the end of the pivoted lever which when released moves or operates the stop
rod to stop the mule substantially as described.
3. A stop motion for mules by which the mule will be stopped when the cops
are full having the several parts constructed and arranged in combination sub-
stantially as described and shown.
