Improvements in Yarn Delivery Motions for Selfacting Mules.
Year: 1895

page_text: I, JAMES WHITEHEAD of 15, Rushcroft Road, High Crompton, Shaw, Oldham,
in the County of Lancaster, Mule-overlooker, do hereby declare the nature of this
invention to be as follows :—
This invention relates to improvements in yarn delivery motions for self acting
mules.
Heretofore in selfacting mules the yaru delivery during the inward run of the
carriage has been effected from the back or drawing out shaft by means of spur
wheels.
The object of my invention is to effect such delivery of yarn, by gearing the
catch box whilst the carriage is out at the head, by means of suitable connections
from the backing-off lever of the mule whereby the yarn is delivered in a much
steadier and more regular manner and a better quality of yarn with less waste is
produced whilst the means employed are much simpler than heretofore has been
the case.
In accomplishing this I fix to or form at a convenient part of the backing off
lever an incline and to a suitable part of the headstock 1 attach a lever one arm of
which engages and governs the gearing and ungearing of the front spindle catch
box and the other arm I furnish with a rod or leg suitably guided and carrying at
its free end an anti-friction bowl, which is kept in contact with the said incline by
means of a spring. When the backing off takes place the said incline through the
medium of the said rod or leg and catch box lever, keeps the said catch box out of
gear whilst when the backing off has ceased the movable catch box part is thrown
into gear by means of the said spring.
The invention described is applicable to all "makes" of selfacting mules,
however in some cases slight modifications may be necessary without departing
from the nature of my invention, that is to effect the delivery of yarn from the
backing off lever by suitable connections.

COMPLETE SPECIFICATION.
Improvements in Yarn Delivery Motions for Selfacting Mules.
1, JAMES WHITEHEAD, of 15, Rushcroft Road, High Crompton, Shaw, Oldham,
in the County of Lancaster, 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 yarn delivery motions for selfacting
mules.
Heretofore in selfacting mules the yarn delivery during the inward run of the
carriage has been effected from the back or drawing out shaft by means of spur
wheels.

page_text: The object of my invention is to effect such delivery of yarn, by gearing the
front spindle catch box whilst the carriage is out at the head, by means of suitable
connections actuated say from the backing-off lever, or faller shaft of the mule
whereby more yarn is delivered, in a much steadier and more regular manner and a
better quality of yarn, with less waste, is produced whilst the means employed are
much simpler than those which heretofore have been in use.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings, showing my improvements as applied
to one of Platts mules, marked with letters of reference indicating like parts in the
various figures.
Fig. 1 is a side view looking from the front of the head-stock of the mule, Fig. 2
a plan and Fig. 3 a side view of my improved yarn delivery motion.
Figs. 4, 5 & 6 are respectively side views and a plan of a modification of my
invention applicable to a mule with single or double driving and for twisting at the
head.
In carrying out my invention and referring to Figs. 1, 2 & 3, according to one
form fix upon a convenient part of the backing-off lever a, say on an arm a
formed thereon, an incline b and to a suitable part of the head-stock I pivot the
lever c, c³, one arm c of which engages and governs the gearing and ungearing of
the front spindle catch box d and the other arm c' I furnish with a rod or leg e
suitably guided, say in the bracket f bolted to the head-stock. The lower end of
this rod or leg e carries an anti-friction bowl e¹, which is kept in contact with the
incline by means of a spring 9, one end of which is attached to the lever arm c
and the other to the bracket which spring also serves to keep the catch box d in
gear during the time the roving is being delivered. When the backing-off takes
place the incline b, through the medium of the rod or leg e, raises the catch box
lever C, and thus throws and keeps the catch box d out of gear whilst when the
backing-off has ceased the sliding part of the catch box is thrown into gear by the
lever c, caud spring 9. The backing-off lever a I may place under the influence
of a spring g¹.
The complete action of the motion described is as follows;-
Whilst the carriage is running out the catch box d is in gear and roving is
being delivered as usual until the carriage has nearly arrived at the end of the
draw. At this point the backing-off lever a moves in the direction indicated by
the arrow and causes the incline 6 to raise the rod or leg e, e¹, lever c, c¹, throw the
catch box out of gear and thus stop the delivery of roving. When the backing-off
red his being pulled back previous to the inward run of the carriage, the
backing-off lever a with its incline b moves back to its former position and causes
the rod or leg e to drop and the spring g to pull the lever c, c' down and thus throw
the catch box d into gear, allowing it to start the rollers.
The motion of the rollers is derived during the inward run of the carriage from
the quadrant of the mule through the medium of the tin roller pulley, the twist band
which drives the rim shaft, a pinion secured upon the latter and geared up by a
carrier with the speed wheel the shaft of which carries the bevel pinion in gear
with the bevel wheel on the fast part of the catch box.
Referring to Figs. 4 & 5 instead of attaching the incline to the backing-off
lever as described, I employ the same on a rod i positioned above the backing-off
rod h, say partly guided in an arm f1 formed on the bracket f and partly on the
head-stock frame & the outer end of the rod i being jointed to a lever the lower
end of which is pivoted to the head-stock frame k, and the upper end acted upon
by the faller shaft m when the carriage arrives at the end of its outward run,
whereby the rod i is drawn in the direction of the arrow and by means of the
incline b, rod or leg e, and lever c, c', the catch box d is thrown out of gear in the
same manner as hereinbefore described. The rod is placed under the influence
of a spring 2 which draws the same back when the faller shaft m leaves the
lever l

page_text: Instead of attaching the lever to the frame k, as shown in Figs. 4 & 5, it may
be suspended from a bracket k¹, as shown in Fig. 6.
The invention described is applicable to all "makes" of selfacting mules,
however in some cases slight modifications may be necessary without departing
from the nature of my invention, that is to effect the delivery of yarn by gearing
the front spindle catch box by suitable means immediately after backing-off.
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-
"In yarn delivery motions for mules."
1st. Gearing the front spindle catch box at the commencement of the inward run
of the carriage for the purpose of effecting an increased delivery of yarn, all
substantially as set forth.
2nd. For the purpose of gearing the front spindle catch box as specified in the
preceding claim, the employment of the catch box lever c, c¹, under the influence
of a spring 9 which keeps the catch box d in gear during the outward run of the
carriage, having attached a rod or leg e in combination with an incline 6 carried by
the backing-off lever a or by a rod i actuated by the faller shaft, which incline is
adapted to throw the catch box d out of gear when backing-off and into gear again
after having backed-off, all substantially as set forth.
3rd. The general construction and combination of parts constituting my improve-
ments all substantially as and for the purpose set forth.
