Improvements in Multiple Needle Shuttle Sewing Machines.
I, HERBERT WAIDE REYNOLDS, of Upper Brown Street, Leicester, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention has reference to sewing machines of the "Singer" type in
which oscillating or rotary shuttles are employed, and has for its object certain
improvements particularly applicable to machines in which three or more needles
and shuttles are employed for the purpose of sewing three or
parallel stitches simultaneously.
more lines of
In machines employing two shuttles it is a comparatively easy task to detach
or take out either of the shuttles from the side of the shuttle race when it is
desired to do so, either for replenishing the thread or for other purposes.
But with a three or more shuttle machine it is impossible to get at the central
or intermediate shuttles without first removing the outside shuttles.
The object of the present invention is to overcome this difficulty by an
improved construction of the shuttle race by which access may be gained to
any one or more of the central or intermediate shuttles when desired, without
the necessity of disturbing any of the other shuttles.
For this purpose, the shuttle race, which is of the well known type, but
enlarged proportionately according to the number of shuttles (three or more) it
is desired to carry, is provided on its peripheral edge or circumference with an
opening or openings and one or more doors to normally close the same.
The said doors may be pivotted or hinged to the shuttle race and provided
with a latch or fastening device of any suitable type to lock it in its closed
position.
In a three needle machine, a single door in the race will suffice, but for a four
or more shuttle machine. two or a correspondingly larger number of doors may
be employed, one for each additional shuttle beyond three if desired.

I, HERBERT WAIDE REYNOLDS, of Upper Brown Street, Leicester, Manufacturer,
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 has reference to sewing machines in which, as those of the

type, oscillating or rotary shuttles are employed, and has for its
object certain improvements particularly applicable to machines in which three
or more needles and shuttles are employed for the purpose of sewing three or
more lines of parallel stitches simultaneously.
In machines employing two shuttles it is a comparatively easy task to detach
or take out either of the shuttles from the side of the shuttle race when it is
desired to do so, either for replenishing the thread or for other purposes.
But with a three or more shuttle machine as at present constructed it is
impossible to get at the central or intermediate shuttle or shuttles without first
removing the outside shuttles.
The object of the present invention is to overcome this difficulty by an
improved construction of the shuttle race by which access may be gained to
any one or more of the central or intermediate shuttles when desired, without
the necessity of disturbing any of the other shuttles, on either side thereof.
For this purpose, the shuttle race, which is of the well known type, but
enlarged proportionately according to the number of shuttles (three or more) it
is desired to carry, is provided on its peripheral edge or circumference with an
opening or openings and one or more doors to normally close the same.
The said doors may be pivotted or hinged to the shuttle race and provided
with a latch or fastening device of any suitable type to lock it in its closed
position.
In a three needle machine, a single door in the race will suffice, but for a four
or more shuttle machine, two or a correspondingly larger number of doors may
be employed, one for each additional shuttle beyond three if desired.
The invention will be understood from the following further description in
reference to the accompanying drawing in which
Figure 1 is a side elevation of a shuttle race constructed according to this
invention and shown with the door in its open position.
Figure 2 is a front elevation of the same with the door closed.
Figure 3 is a central vertical section through the shuttle race and the shuttle
driver, and showing a shuttle in elevation.
Figure 4 is a side elevation of the shuttle driver and a part of its actuating
rock shaft.
"
A, represents a shuttle race belonging to a
which rotary or oscillating shuttles are employed; B represents a rotary shuttle
Singer's" sewing machine with
and C represents the shuttle driver, all of which except as hereinafter described
are constructed and operated in the usual well known manner.
The ordinary shuttle race is provided on its inner face with parallel circular
grooves in which the rotary shuttles B are located side by side with each other
and when two shuttles are employed it is a comparatively easy matter to remove
either of them when required through the opening D in the end of the race,
without disturbing the other shuttle.
When three shuttles are employed one of the end shuttles must first be
removed before the central shuttle can be got at, and when more than three
shuttles are used, all the shuttles intermediate of the one to be removed and the
end shuttle including the latter must be first taken out.
According to this invention a through opening or entrance E to the interior
of the shuttle race is made in the wall of the latter and this opening or entrance
is closable by a door F movable on a pivot F¹ passing through the wall of the
race and across the lower part of the said opening E and through the door F.
The door may be provided with a knob F or equivalent to facilitate its opening
and a set screw F3 passing through the side of the race and into a notch F' in
the side of the door is employed to fasten the latter in its closed position.
Other means than the screw F3 may be employed for locking the said door.
When the width or depth of the opening in the race is such that the operator's
fingers cannot be inserted to extract the shuttle, tweezers may be used for that
purpose.

page_text: When four or a greater number of shuttles are used one, two or more doors
may be provided as desired.
With each additional shuttle employed an extra slot C¹ is made in the driver
for the shuttle thread to pass through.
The door may be hinged to the race in any other convenient manner than
described with reference to the pivot F¹.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is.-
1. In a multiple needle shuttle sewing machine, a shuttle race constructed
in such a manner as to afford access to any of the shuttles intermediate of the
end ones without disturbing the latter.
2. In a multiple needle shuttle sewing machine, a shuttle race having one or
more entrances or through openings therein to afford access to the shuttles inter-
mediate of the end ones, one or more doors to close the said entrances and means
for locking the said doors in their closed positions.
3. In a multiple needle shuttle sewing machine, a shuttle race having an
entrance or through opening therein and a closable door thereto and means for
locking the said door, constructed and arranged substantially as hereinbefore
described and illustrated in the accompanying drawing.
