IMPROVEMENTS IN SHUTTLES
Year: 1884

page_text: I JONATHAN SELLERS of Preston in the County of Lancaster Bobbin and Shuttle
Manufacturer, do hereby declare the nature of said invention for IMPROVEMENTS IN
SHUTTLES, to be as follows:-
First in making the spring of the shuttle tongue to rise by pressing forward the
end of the spring whilst closing the tongue after a cop has been put on thereby
raising the body of the spring and thus holding the cop firm in the tongue whilst
weaving.
Second-In using a flat or square wire for the tongue to rest on which can be
reversed as the wire wears.
Third-In using an adjustable screw for the shuttle tongue to rest in And
making this screw with a point fitting into a recess or counter sink made in the
head of the tongue to prevent side or latteral vibration.
Fourth In making a shuttle with a solid bottom-with the exception small
opening to admit of the finger to press up the tongue-in combination with the
common tongue shuttle.
Fifth In making the opening in the body of the shuttle to taper gradually at
each end nearly to the shape of the cop instead of making the opening nearly
parallel as at present thereby materially strengthening the shuttle.

COMPLETE SPECIFICATION.
I JONATHAN SELLERS of Preston in the County of Lancaster, Bobbin and
Shuttle Manufacturer do hereby declare the nature of said invention for IMPROVE.
MENTS IN SHUTTLES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
First In making the spring of the shuttle tongue to rise by pressing forward
the end of the spring whilst closing the tongue after a cop has been put on thereby
raising the body of the spring and thus holding the cop firm on the tongue whilst
weaving.

page_text: I do this as follows-Fig. 1. in the accompanying sheet of drawings shews a
section of the wood part of a shuttle with my improved tongue, a is the shuttle-
tongue through the head of which I bore longitudinally the hole b, through which
I insert the spring c, the one end of which I attach to the point of the tongue in
the usual manner the other end to be loose in the hole b in the head of the tongue
and to project a short distance beyond it, this projecting part to be formed like
a T head shewn in Fig. 3. when the tongue is raised as shewn in Fig. 2. to put
on a cop the spring c is lying nearly flat on the tongue a and the cop is easily put
on but in closing the tongue the T head end of the spring which projects beyond
the shuttle head acts against the square headed plug d, which works in the spiral
spring i inserted in the wood part of the shuttle (or any convenient object fixed in
the shuttle for that purpose) thus pressing forward the spring c, and as the spring
at the other end is fixed at the point of the tongue that part of the spring betwixt
the hole in the shuttle head and the point of the tongue is raised and holds the cop
firm in position.
Second-In using a flat or square wire e. Fig. 2 for the tongue to rest upon
which can be reversed as the wire wears.
Third-In using an adjustable screw f Fig. 1 for the shuttle tongue to rest upon
and making this screw with a taper point fitting into a recess or countersink
made in the head of the tongue (as shewn in the drawing) to prevent side or lateral
vibration.
Fourth In making the ordinary tongued shuttle with a solid bottom as shewn
at g. Fig. 1. with the exception of a small opening h to admit of the finger to press
up the tongue.
Fifth-In making the opening in the body of the ordinary shuttle to taper at
each end nearly to the shape of the cop as shewn in Fig. 3 instead of making
the opening nearly parallel as at present, thereby materially strengthening the
shuttle.
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:
First Making a shuttle tongue with a spring to rise in the centre by being
pressed forward at the shuttle head when closing, as described.
Second-Using a flat or square wire for the tongue to rest upon.
Third Using an adjustable screw for the tongue to rest upon with a taper
point fitting into a countersink or recess in the head of the tongue to provent
lateral vibration.
Fourth Making the ordinary tongued shuttle with a solid bottom as described.
Fifth Making shuttles with the opening in the body tapering gradually at each
end as shewn in the drawing.
