IMPROVEMENTS IN SHUTTLES
Year: 1884

page_text: I, JOHN HARVEY of 15 Morpeth Street Lister Hills, Bradford in the County
of York, Shuttle Maker, do hereby declare the nature of my invention for
IMPROVEMENTS IN SHUTTLES to be as follows:-
The object of this invention is to supersede the hinged tongue or "pike" in the
shuttle as hitherto constructed which is apt to fly up and make a trap causing
damage to the piece which is being woven.
•
I accomplish my object by fixing into the "pike" end of the shuttle a horizontal
clip in two halves which grip round the bobbin head: the bottom half of this clip
is secured to the shuttle by screws the upper half, of which is similar in shape to
the bottom, is centred by one pin about the middle of its length underneath the
end nearest the tip of the shuttle is a spiral.spring which ensures the clip gripping
round the bobbin head by pressing down the end over the spiral spring the other
end lifts and releives the bobbin from the clip when it is desired to replace one
bobbin with another.

COMPLETE SPECIFICATION.
I, JOHN HARVEY, of 15 Morpeth Street Lister Hills; Bradford, in the County
of York, Shuttle Maker, do hereby declare the nature of my invention for
IMPROVEMENTS IN SHUTTLES," and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:—
H
The object of this invention is to supersede the hinged tongue or "pike" in the
shuttle as hitherto constructed, which, after the shuttle has been at work for a
D

page_text: short time, is apt to fly up and wako a trap, thereby causing damage to the piece
that is being woven; and consists in fixing into what is known as the "pike" end
of the shuttle, a horizontal clip in halves, one half being secured to the shuttle,
and the other hinged on a pin. The bobbin head is placed between the two
portions of the clip and held therein by a short catch arm and spring.
In the accompanying drawings Fig 1. represents the side view of a shuttle
having a portion cut away in order to show my improved clip, which is open for
the reception of a bobbin. Fig 2, shews the clip closed gripping the bobbin head,
Fig 3, is a plan of the top half of the clip and Fig 4 is a longitudinal section
through the top and bottom portions.
The bottom half A, of the clip is secured in a recess, and the top half B, is hinged
on a pin passing through the shuttle. When the top half B. (as shown by Fig 1.)
is raised for the reception of a bobbin head, it is held in that position by the end
passing under the catch formed on short arm 0; and on placing the bobbin head H
between the enlarged ends of the clip, the short arm C, is pushed back to allow
the top half of clip B. to grip the bobbin head, which is held securo by the reduced
portion C, of short arm C, passing into a slot B', formed in the end of B, and is
held therein by spring S. pressing against the said short arm as shown by Fig 2.
In order to allow for bobbin heads of varying diameters, I cut in the short
arm C. a slot hole, and pass a pin through the same; the spring. S. pressing against
the underside of short arm C. keeps the same in contact with the end of B. When
the bobbin heads are of the proper diameter the pin is in the centre of the said
alot; but should any of the bobbin heads vary in diameter, when the same are
placed between the said clip, the slot hole in the short arm C, allows the top portion
of the clip B, to accomodate itself to the size of the bobbin head, the spring S,
pressing on the underside of the said short arm, keeps the bobbin secure between
the clip.
By mounting clips in the shuttles as described, what is commonly known as the
'pike slot
or recess is not cut so near to the tip T, as when hinged tongues or
pikes" are used, therefore the shuttle is stronger and not so liable to expand in
the said slot through the boating of the shuttle, as is the case when "pikes" are
used.
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
Clips for securing bobbins in shuttles arranged substantially in the manner shown
and described.
