PROVISIONAL SPECIFICATION.
Improvements in Yarn Delivery Motions for Self-acting Mules.
I, JOHN LORD, of 31, Turf Lane, Hollinwood, in the County of Lancaster,
Mule-overlooker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to yarn delivery motions for selfacting mules such as are
designed to give out a certain amount of yarn during the inward run of the
carriage.
The invention has for its object to provide means whereby the said delivery of
yarn is effected in a more simple and reliable manner and which may be readily
applied to any make of selfacting mule.
To this end my improvements consist essentially in the employment of a lever
reaching from the front spindle catch box to near the outer end of the head-stock
and adapted to rock upon a stud, say upon the stud which carries the change
lever.
The inuer end of the said lever carries a bracket having an incline arranged in
contact with a bowl on a stud attached to the die socket of the front spindle catch
box lever, which latter is placed under the influence of a spring adapted to retain
the said catch box in gear during the required time. The outer end of the said
lever is furnished with another bracket having an incline, with which the faller
shaft contacts at the end of the outward run of the carriage and whereby the said
lever is caused to rock and its inner incline caused to throw the front spindle catch
box out of gear. The outer end of the said lever may be placed under the
influence of a spring to assist in bringing it back to its normal position the moment
the carriage commences its inward run.

Improvements in Yarn Delivery Motions for Self-acting Mules.
I, JOHN LORD, of 31, Turf Lane, Hollinwood, 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 yarn delivery motions for selfacting mules such as are
designed to give out a certain amount of yarn during the inward run of the
carriage.
The invention has for its object to provide means whereby the said delivery of
yarn is effected in a more simple and reliable manner and which may be readily
applied to any make of selfacting mule.
And in order that my invention may be more fully understool I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.

page_text: Figs. 1 & 4 are side views, Fig. 2 a plan and Figs. 3 & 5 sectional end views of
a portion of the mule head stock to which my improvements are applied. Figs. 6
& 7 are respectively a similar side view and sectional end view showing a
modification of my invention.
In carrying out my invention and referring to Figs. 1, 2, 3, 4 & 5, the improve-
ments consist essentially in the employment of a lever a reaching from the front
spindle catch box b to near the outer end of the head-stock and adapted to rock
upon a stud, say upon the stud c which carries the change lever d.
The inner end of the lever a carries a bracket a' having an incline a arranged
to act in contact with a bowl e carried by a stud el attached to the die socket of
the front spindle catch box lever f', which latter is placed under the influence of a
spring 9 adapted to retain the said catch box in gear during the required time.
The outer end of the lever a is furnished with another bracket h having an incline /¹
with which the faller shaft i contacts at the end of the outward run of the carriage,
see Fig. 1, and whereby the lever a is caused to rock and take up the position
shown in Fig. 4, which causes its inner incline a to rise and throw the front spindle
catch box bout of gear, see Fig. 5. The onter end of the lever a may be placed
under the influence of a spring k to assist in bringing it back to its normal
position, shown in Figs. 1, 2 & 3, the moment the carriage commences its
inward run.
According to a modification of my invention, see Figs. 6 & 7, I form the
bracket a' at the inner end of the lever a with a second incline a³ and to the said
end I secure another bracket 1 having also an incline . This latter incline is so
positioned that when the mule carriage is arriving at the end of its inward run, the
faller shaft contacts with it and depresses the respective lever end which causes
the second incline a³ to act upon the catch box lever and thus throw the front
spindle catch box a second time out of gear, i.e. during the time the cam reverses
the direction in which the mule carriage runs, a spring being employed at the
outer end to bring the lever a back to its normal position.
This modification has for its object to prevent snarls which are liable to form on
the threads particularly in finer numbers.
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 selfacting mules, a rocking lever a each end of
which carries a bracket al & h having an incline a² & respectively, the inner
incline a being arranged in contact with a bowl e carried by the front spindle catch
box lever fin such a manner that when the faller shaft i arrives at the end of the
outward run of the carriage it will contact with the incline depress the
respective lower end, raise the inner end and by means of the respective incline a³
throw the front spindle catch box b out of gear, all substantially as and for the
purpose set forth.
