Improvements in "Swells" of Shuttle Boxes of Looms for
Weaving.
We FREDERICK BAYNES of Ciceley Bridge Mills, Blackburn in the County of
Lancaster, Cotton Spinner and Manufacturer and JOSHUA WHALLEY, of Ciceley
Bridge Mills, aforesaid, Manager, 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 the "swells" and the mountings for
carrying the same of shuttle boxes of looms for weaving, and the object is to
construct a "swell" as to render it more durable, and effective than the one heretofore
in use, and consists of the "swell" proper which is carried by a short arm cast to the
"swell" and at right angles to the same; the upper end of the said arm or lever
being formed of hook shape, the said hook being received on, a pin or stud and
forming a bearing or hinge on which the "swell" moves, and from which it can
readily be detached if necessary, or in lieu of forming the end of the arm in a hook
like joint we cast a boss thereon through which a hole is drilled for the reception of a
through pin to one end of which is cast a lug or ear secured by screw to the back of
the shuttle box, a second lug or ear is secured to the opposite end of the through pin
and the whole is then fixed in position.
Such being the nature and object of this our said invention, the following is a
complete description of same reference being had to the accompanying drawings in
which
Fig. 1. is a back view of part of a shuttle box of a loom with our improved "swell"
applied thereto.
Fig. 2. is a cross section on line A. B, of Fig. 1. the shuttle being in the "race" i.e.,
not boxed.
Fig. 3 is a similar view to the one illustrated by Fig. 2. but the shuttle is shewn
"boxed" and operating the "swell."
Fig. 4 is an oblique view of the "swell" with the hook like hinge or joint.
Fig. 5 is a back view of part of a shuttle box the "swell" being mounted on an
ordinary through pin.
According to this our said invention the "swell" 1 or that portion which comes in
contact with the shuttle 2 when the latter is "boxed" is formed of equal strength and
thickness throughout, not, as is usually the case, having the lower edge 3 bevelled off,
for the purpose of bearing down on the shuttle 2 when "boxed." Cast to the back,
and forming part of the "swell" 1 is a short arm or lever 4 on the lower end 5 of
which arm or lever 4 bears the ordinary blade spring 6 and the upper end of the said
arm or lever 4 terminate in a broad hook like hinge 7 which hook is readily placed on
and carried by the pin or cross rod 8 to each end of which is cast a lug or ear 9
which lugs or ears are fixed to the back of the shuttle box 10 by screws, and the hook
like hinge is carried between the lugs or ears 9, so as to prevent lateral motion of the
"swell."
In lieu of carrying the swell by the hook like joint or hinge 7 above
described we, in some cases prefer to form a boss 11 at the end of the arm or lever 4
(see Fig. 5) through which a hole is drilled for the reception of a through pin 12 one
end of which through pin 12 terminates in a lug or ear 13 fixed by screw to the back
of the shuttle box 10, to prevent lateral movement of the "swell" a lug 14 is passed
over the opposite end of the through pin 12 (after the boss 11 and swell are in
position) which lug is also fixed to the back of the shuttle box 10 by a screw, thus
the "swell" can be removed if necessary by simply unscrewing and withdrawing the
lug 14, or in the first described device by unhooking 7 from its cross rod 8.
The advantages of the above described "swell" are its durability and its
effectiveness, as it will be seen by Fig. 1. that the pressure of the blade spring 6 is

page_text: applied directly to the centre of the "swell" 1 and by referring to Fig. 3 it will be
seen that when the shuttle 2 enters the box and comes in contact with the "swell" 1
the latter partly overhangs the top or upper surface of the shuttle and by reason of
the angle of inclination assumed by the acting surface of the "swell" the upper
portion of the latter overhanging the shuttle and the tendancy of the shuttle to fly out
of the box is prevented or reduced to a minimum.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
-
1. The improved appliances herein described comprising a "swell" attached or cast
to a swinging arm such as 4 the returning spring 6 acting on the said arm 4 all the
parts in combination and substantially as illustrated by the annexed drawings.
