PROVISIONAL SPECIFICATION.
Improvement relating to the Weighting of the Rollers of
Self-acting Mules.
JOHN THOMAS LAMBERT 408 Cheetham Hill Road Dukinfield, Cheshire
Tester and Examiner of Yarns in a Cotton Mill, do hereby declare the nature
of this invention to be as follows:-
The invention is in connection with a selfacting mule, and refers to the weighting
of the rollers. The rollers are weighted by means of what is known as lever
weighting.
A saddle rests on the rollers with a wire attached to it, the wire passes through
the roller beam to a lever with the fulcrum at one end, and a weight at the other,
on the lever between the fulcrum and weight and near the fulcrum end, arè two feet,
which rest on an adjusting nut attached to the saddle wire, if this adjusting nut is
not placed in the proper position, it causes the saddle wire to press against the roller
beam & rollers, thus taking part of the weight off the rollers.
My invention is an improvement on this adjusting nut, and is made in such a form,
as to prevent the feet of the lever being placed in the wrong position thus causing
the weighting to be more even.
Dated this 22nd day of March 1893.
COMPLETE SPECIFICATION.
Improvement relating to the Weighting of the Rollers of
Self-acting Mules.
JOHN THOMAS LAMBERT 408 Cheetham Hill Road Dukinfield Tester and
Examiner of Yarns in a Cotton Mill 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:—
My invention is an improvement relating to the weighting of the rollers of self-
acting mules roving & ring frames.
The rollers are weighted by means of what is known as lever weighting. A
small saddle A rests on the rollers B on the top of this small saddle a larger saddle C
rests, connected to this are the wires E and E', the latter wire E¹ passes through
the roller beam F to a lever G with the fulcrum at one end and the weight at the
other, on the lever between the fulcrum and weight and near the fulcrum end are
two feet or projections H which rest on an adjusting nut I, screwed on the saddle
wire E' if the adjusting nut I is not placed and retained in its proper position it
causes the wire E' to press against the roller beam F and rollers B, 1, 2 or 3. The
lower end of the wire at K coming in contact with the beam F at J will bind and
prevent an easy and accurate adjustment or distribution of the weight on the
rollers B, 1, 2, 3.
My invention is an improvement on this adjusting nut and is made in such a form
as to prevent the feet H of the lever G being placed in the wrong position or
working out of the right one.
I dispense with the present nut and put on a nut with one groove only, having
two horns or snugs L cast on as shown in Fig. 1 or the like projections otherwise
attached

page_text: When the rollers are taken out the lever G falls between the two horns L
see Fig. 2. If the lever moves on one side it must be brought back to its original
position as the horns are so arranged that when the lever is raised to its highest
point it cannot get over the top. In this manner the evil of the nut working down
is done away with. The feet H of the lever G cannot get into a wrong position,
being so arranged that they will positively fall into the groove M of the nut I
which groove may be of round V or other form.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
1. In or in connection with roving frames ring frames or selfacting mules
employed in the spinning of fibrous material improvement in the weighting of the
rollers especially where the weight and lever is adopted by means substantially
as herein before described whereby the weight upon the rollers is maintained
uniformly.
2. In combination with the weight wire and lever a nut of the form described
or if preferred may be V shape or other form of groove, having horned projections
cast or otherwise attached thereto for the purposes and arrangements herein before
described.
3. A modification of the above arrangement may be effected by casting or
otherwise attaching a snug or snugs or such projections as may be termed its
equivalent.
