Office of the Commissioners of Patents, with his Petition, on the

I, JOEL H. LE MOYNE, of Boston, in the County of Suffolk, in the
State of Massachusetts, one of the United States of America, do hereby
declare the nature of the said Invention for "A COMBINED MULE AND
SHUTTLE SPINDLE," to be as follows:-
-
My Invention relates to improvements in mule spindles and consists
in making such spindles in two parts, on the upper one of which the cop
is spun, after which I detach the upper part of said spindle with the
cop on it from the lower part thereof, and secure such upper part of a
mule spindle with the cop on it in a suitable manner to a loom shuttle,
by which arrangement the cop is placed in a loom shuttle without being
transferred from the original spindle on which it was spun in the mule.
The extreme end of this my improved mule spindle I provide with an
enlargement or swell so as to prevent the cop from breaking when it is
used in the loom shuttle; this I am able to do because I do not transfer
the cop from the mule spindle after it is spun thereon, and consequently

page_text: I am enabled to spin the cop as firmly as possible on the mule spindle,
and I may if I so desire it spin the cop thereon between two swells,
enlargements, or collars, without departing from the spirit of my
Invention, which is to make a mule spindle in two parts that are held
together in a suitable manner when the cop is spun thereon in the mule;
the upper end of the said mule spindle is detached from its lower part and
inserted with the cop on it in a loom shuttle. In this manner I save a
great deal of labor in the operation of spinning and weaving, as by my
Invention one and the same spindle does service both in the mule and
the loom shuttle, in addition to which I am able to prevent unnecessary
waste of the cops, as no breaking of the latter can occur by my Invention
because I spin the cop so firmly on the mule spindle from which it is
not transferred till it is gradually fed out from the shuttle in the
operation of weaving.
I wish to state that I do not confine myself to any exact device for:
securing and detaching the upper part of my improved mule spindle to
and from the lower part thereof or to and from the loom shuttle.
On the accompanying Drawing Fig. 1 represents a side elevation
of my improved mule spindle; Fig. 2 represents a central longitudinal
section of the same.
Fig. 3 represents a ground plan of a loom shuttle in which the
upper part of my improved mule spindle is secured; and Fig. 4
represents a central longitudinal section of Fig. 3.
a, b, represents my improved mule spindle of which a is the lower and
6 the upper part that are joined together at c, one part being for this
purpose provided with a socket or its equivalent device, and the other
part with a corresponding projection or similar device provided with
frictional springs or a similar locking device by means of which the part
6 is made to form as it were one single piece with the part a, during the
operation of spinning the cop on the said upper part 6, which is provided
near its extreme upper end with a swell enlargement or collar d or
equivalent device so as to prevent the breaking of the cop when the
said upper part is used afterwards in the loom shuttle. A small
projection is made on one or the other part of my improved mule spindle
that fits into a corresponding recess on the other part of the said spindle
so as to make both parts revolve together during the process of spinning
in the mule.

page_text: In Figs. 3 and 4 the upper part 6 of my improved mule spindle is shown
inserted in the loom shuttle e, for which purpose I provide the head f
with a short projecting shank g fitting in a corresponding recess in the
rear of the spindle b, and to further secure the latter to the shank g I
employ a nut ½ that engages with a screw thread, cut both on the shank
g and spindle 6 or by an equivalent device so as to attach the spindle
> when used in the shuttle so firmly to the shank g, that it may form
as it were one single piece with the latter during the operation of
weaving. When the cop is all used up in the shuttle I remove the
spindle 6 from the shuttle and by securing it to the part a in the mule
in the manner as herein above set forth, I repeat the operation of
spinning a cop thereon, after which the spindle and its cop are trans-
ferred to the loom shuttle, and so repeativly in the manner herein above
described.
