PROVISIONAL SPECIFICATION.
Improvements in Appliances connected with the Shuttle Boxes of
Looms.
We GILES PARKINGTON of No. 1 Plymouth Street, Blacksmith, and JONAS
HINDLE of Greenbank Mill, Cotton Manufacturer, both of Blackburn, in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to improvements in appliances connected with shuttle
boxes of looms for weaving the object being to simplify the construction of such
boxes, and to improve the running, or working of the shuttle by causing it to run
much truer, and easier, preventing it flying out or turning over, and also acting as
an effective picker, and check strap preserver.
According to this our said invention the shuttle box is made as ordinary, but the
"swell," and its spring are dispensed with, and the shuttle guide is made somewhat
similar to that heretofore employed, but is mounted at the end nearest to the
entrance of the shuttle box on a pin, or stud which acts as a fulcrum ; the opposite
end of the shuttle guide is free to vibrate, and is formed with a cross piece the end
of which rests against the back of the shuttle box, or against an adjusting screw or
out therein, and this the vibrating end of the shuttle guide is maintained in the
required position by means of a blade spring fixed to the front of the shuttle box.
The cross piece which forms part of the vibrating end of the shuttle guide is
slightly less in length than the width of the ordinary shuttle, and as the latter
enters the box the vibrating guide acts in lieu of the swell" the pressure of the
blade spring checking the momentum of the shuttle, and stopping it.
The fulcrum pin of the guide may work in a short longitudinal slot in such guide,
and the check strap being attached to the guide the latter, or the cross piece of it,
will act as a "buffer."

Improvements in Appliances connected with the Shuttle Boxes of
Looms.
We, GILES PARKINGTON of No. 1 Plymouth Street, Blacksmith and JONAS
HINDLE of Greenbank Mill Cotton Manufacturer, both of Blackburn in the
County of Lancaster, 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 improvements in appliances connected with shuttle
boxes of looms for weaving the object being to simplify the construction of such
boxes and to improve the running, or working of the shuttle by causing it to run
much truer and easier preventing it flying out or turning over and also acting as an
effective picker and check strap preserver.
According to this our said invention the shuttle box is made as ordinary but the
"swell" and its spring are dispensed with and the shuttle guide is made somewhat
similar to that heretofore employed, but is mounted at the end nearest to the
entrance of the shuttle box on a pin, or stud which acts as a fulcrum, the opposite
end of the shuttle guide is free to vibrate and is formed with a cross piece the end
of which rests against the back of the shuttle box or against an adjusting screw or
n

page_text: nut therein and thus the vibrating end of the shuttle guide is maintained in the
required position by means of a blade spring fixed to the front of the shuttle box.
The cross piece which forms part of the vibrating end of the shuttle guide is
slightly less in length than the width of the ordinary shuttle, or a "swell" is
formed on the guide and as the shuttle enters the box the vibrating guide acts in
lieu of the ordinary "swell" the pressure of the blade spring checking the
momentum of the shuttle and stopping it.
The fulcrum pin of the guide may work in a short longitudinal slot in such
guide and the check strap being attached to the guide, the latter or the cross piece
of it will act as a " buffer."
Such being the nature and object of our invention the following is a complete
description of same reference being had to the accompanying drawings forming a
part of this Specification in which :-
Fig. 1 is a front elevation of a shuttle box of a loom for weaving having our
improvements applied thereto.
Fig. 2 is a plan view of Fig. 1.
According to this invention the shuttle box is made as ordinary but the "Awell"
and its spring are dispensed with. The shuttle guide is made somewhat similar
to that heretofore employed but is mounted at or near the end 2 (nearest to the
entrance to the shuttle box) on a pin or stud 3 which acts as a fulcrum. The opposite
end 4 of the shuttle guide 1 is free to vibrate, the guide moving on its fulcrum
pin 3 and the end 4 of the guide 1 has a cross piece or head 5 cast to it. One end 6
of the cross head 5 rests against the back 7 of the shuttle box or against an
adjusting screw or nut therein and thus the vibrating end 4 of the shuttle guide 1
is maintained in its required normal position by means of a blade spring 8 fixed by
screws to the front 9 of the shuttle box. By making the end or part 6 of the cross
head 5 slightly less in length than the width of the shuttle 10 or by casting or
forming a "swell" or projection 11 on the inner face of the shuttle guide 1 (see
Fig. 2) the vibrating shuttle guide 1 acts in lieu of the ordinary "swell" as the
spring & by acting on the guide 1 causes the latter to nip the shuttle 10 by the
guide 1 pressing the shuttle against the back 7 of the shuttle box thus checking
the momentum of the shuttle and gradually stopping it.
It may be arranged by regulating the size or shape of the swell 11 that the
shuttle 10 will before being stopped come in contact with the cross piece 6 thereby
knocking or sliding the guide 1 towards the end 12 of the shuttle box, the guide
having a longitudinal slot 13 formed in it to receive the fulcrum pin or stud 3.
this case the ordinary check strap is attached to the guide 1 and the latter or the
cross piece 6 will act as an efficient "buffer" for the shuttle.
In
By the use and employment of the improved form of shuttle box as herein
described a great saving in pickers, picking bands and check straps is effected and
by reason of the shuttle being "picked" or ejected from the box with accuracy
catching and cutting of the weft, turning and ribbing of the shuttles is obviated and
the shuttle is less liable to fly out of the race.
Having now particularly described and ascertained the nature and object of
the said invention and in what manner the same is to be performed we declare that
what we claim is :
1. The vibrating or vibrating and moveable shuttle guide 1 preferably having a
cross head or projection and the spring 8 all in combination with a shuttle box as
and for the purpose herein described and substantially as illustrated by the
accompanying drawings.
