Improvements in Loom Shuttles.
I, ISAAC RUSHWORTH, of Jamestown, in the County of Chautauqua, and State.
of New York, United States of America, Gentleman, 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 loom shuttles for weaving in textile and other fabrics,
and it has for its object to effect certain improvements in the spindles for shuttles of
this character whereby the manipulation and working of the bobbin is rendered
easier and with less injury thereto. To this end the main and primary object of
the present invention is to provide a new and useful two-part or separable spindle
for shuttles which shall provide simple and efficient means for removing and
replacing the bobbins while at the same time avoiding the breakage of bobbins
while placing them in position as is the case in the ordinary split or bowed spring
spindles, and also providing a spindle which will not spoil the small end of the
bobbin as in some styles of spindles and will provide a spindle on which broken
bobbins may be placed so that the filling or yarn may be used.
With these and other objects in view which will readily appear as the nature of
the invention is better understood, the same consists in the novel construction
combination and arrangement of parts hereinafter more fully described, illustrated
and claimed.
In the accompanying drawings:
:-
Fig. 1 is a top plan view of a loom shuttle provided with the improved spindle.
Fig. 2 is an enlarged detail elevation of the spindle with the bobbin thereon
removed from the shuttle body.
Fig. 3 is an enlarged detail view of a portion of the spindle.
Fig. 4 is a similar view of the removable spindle locking pin.
Referring to the accompanying drawings, 1 designates a loom shuttle body of the
ordinary general construction having the opposite pointed ends and provided with
a longitudinal body slot 2, in which is arranged to work the bobbin spindle 3. In
the present invention the bobbin spindle 3 is a cylindrical perfectly straight bar of
metal of the same diameter from end to end of its bobbin receiving portion, and is
provided at its rectangular end with the perforation 4, which receives the pivot
pin 5 that is secured in one end of the shuttle body to pivot the spindle 3 therein in
the ordinary manner, and at this end of the spindle is arranged the ordinary spindle
spring for normally holding the spindle within the slot of the body in the ordinary
manner, but since nearly all types of shuttles are provided with these features of
construction the same are not further illustrated in the drawings.
The straight pivoted bobbin spindle 3 is provided near its point of pivot with the
collar 4 against which is held the large end of an ordinary shuttle bobbin 5*, that
is adapted to be slipped onto the cylindrical portion of the spindle 3, and to be
carried thereby during the operating of the shuttle, and at its other swinging end
the said bobbin spindle is centrally bored with a longitudinal recess 5", and is
provided with a longitudinally disposed guide slot 6, extending in from that end
At the inner
thereof and communicating with the longitudinal bore or recess 5ª.
end of the longitudinally-disposed guide slot 6 the bobbin spindle is further provided
with a short end slot 7, leading from the slot 6, at right angles and extended into
an offstanding lock notch or recess 8 that is disposed at right angles to the
slot 7 and is disposed in a substantially parallel plane with the guide slot 6.
The longitudinal recess 5* in one end of the spindle 3 is adapted to removably

round bar of metal and is provided near one end with the short offstanding lock stud 10
that is adapted to be guided through the slot 6, and the end slot 7, into the notch
or recess 8, when the spindle locking pin 9 is being placed in position and is
correspondingly guided out of the slots when the said spindle locking pin is being
removed.
The removable spindle locking pin 9 is provided at its outer end with the finger
flange or collar 11 against which bears one end of the spring 12 coiled on one end
of the spindle locking pin 9, and adapted to have its other end fit over the neck 13
at one side of the sliding or removable retaining collar 14, that slides on the spindle
locking pin 9, and is provided at one side opposite the neck 13 with the circular
recess 15, which fits over the free end of the spindle 3, in order to allow the
collar 14 to be pressed by the spring 12 against one end of the bobbin 5* to force
the same against the collar 4 and retain it properly in position on the spindle, while
at the same time serving to retain the spindle locking pin 9 in locking engagement
with the spindle by reason of the tension of the spring bearing there-against,
and it is to be further noted that the collar 14 has a rounded periphery and
is designed to be of a larger diameter than the bobbin so that any roughness
on the bobbin will not interfere with the free and easy unwinding of the filling
or yarn.
To remove a bobbin from the spindle 3, it is simply necessary to lift the spindle
out of the slot of the shuttle body in the ordinary manner, then by pressing
inwardly on the finger flange or collar 11, the stud 10 may be disengaged from the
notch or recess 8. It is then simply necessary to turn the spindle locking pin 9 in one
direction to carry the stud 10 through the short slot 7 into the slot 6 out of which
the stud 10 will slide by pulling the spindle locking pin 9 out and the old bobbin
may be taken off and a new one readily replaced. After positioning a new or
filled bobbin, the spindle locking pin 9 is again inserted into the recessed end of the
spindle 3, and by pressing on the flange or collar 11 against the tension of the
spring 12, the stud 10 may be again engaged with the notch or recess 8, and held
in engagement therewith by said spring.
The many advantages of the herein-described spindle have already been referred
to and will be readily appreciated by those skilled in the art, and I will have it
understood that changes in the form, proportion and the minor details of construction
may be resorted to without departing from the principle or sacrificing any of the
advantages of this invention.
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. The combination of a straight spindle adapted to be pivotally mounted at one
end within a shuttle body and provided with an opposite hollow end having a locking
notch or recess, a removable spindle locking pin adapted to register in the hollow
end of the spindle and having a stud adapted to removably engage said notch or
recess, and a flange or collar at one end, a circularly recessed retaining collar
mounted to slide on said spindle locking pin and adapted to have its recess receive
one end of the spindle, and a spring arranged between the sliding collar and the
flange or collar at one end of the spindle locking pin, substantially as set forth.
2. The combination of a straight spindle adapted to be pivoted at one end
within a shuttle body and provided at its other end with a longitudinal recess or
bore 5ª, a longitudinally disposed guide slot communicating with said recess, a short
end slot at the inner end of the guide slot, and an offstanding lock notch or recess
communicating with said end slot, a removable spindle locking pin adapted to
register in said longitudinal recess of the spindle and provided with a lock stud
adapted to pass through said slots into and out of engagement with said lock notch
or recess, a fixed flange or collar arranged at one end of said spindle locking pin,

page_text: a movable recessed retaining collar mounted to slide on said pin, and a spring
interposed between said collars, substantially as set forth.
