Complete Specification Left, 14th Feb., 1891-Accepted, 14th Mar., 1891
PROVISIONAL SPECIFICATION.
Improvements in the "Swells" of Shuttle Boxes of Looms for
Weaving.
We, FREDERICK BAYNES, Manufacturer, JAMES EDWARD TOPPING, Mechanic,
and JAMES WHITTAKER, Mechanic, all of Cicely Bridge Mill, Blackburn, in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to improvements in the "swells" of shuttle boxes of
looms for weaving, and the object is to construct "swells" which are more effective
in operation, and less complicated, and expensive in construction than heretofore,
and which can readily be applied to existing looms.
According to this our said invention the swell is received, and works loosely in
the ordinary slot formed at the back of the shuttle box, and at the back of the swell
is cast a lug, and two, or more pins, or studs; against the lug bears, and presses one
end of a blade spring, the other end being fixed to the shuttle box, and the two
studs, or pins pass, and work freely through corresponding holes formed in a bracket
bolted or fixed by screws to the back of the shuttle box, the holes in the bracket
serving to carry, and guide the swell when forced outwards by the shuttle coming
in contact with its inner face, or inwards by the pressure of the blade spring.
When the swell is forced sufficiently far into the shuttle box by the blade spring, the
ends of the swell come in contact with the back of the shuttle box, and prevent
further movement of the swell, and the pins, or studs of the latter being moved out
of the carrying holes in the bracket.

COMPLETE SPECIFICATION.
Improvements in the "Swells" of Shuttle Boxes of Looms for
Weaving.
We,
FREDERICK BAYNES, Manufacturer, JAMES EDWARD TOPPING, Mechanic,
and JAMES WHITTAKER, Mechanic, all of Cicely Bridge Mill, 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 the "swells" of shuttle boxes of
looms for weaving, and the object is to construct "swells" which are more effective
in operation, and less complicated, and expensive in construction than heretofore
and which can readily be applied to existing looms.
According to this our said invention the swell is received, and works loosely in
the ordinary slot formed at the back of the shuttle box, and at the back of the swell
is cast a lug and two, or more pins or studs; against the lug bears, and presses one
end of a blade spring the other end being fixed to the shuttle box, and the two
studs or pins pass and work freely through corresponding holes formed in a bracket
bolted or fixed by screws to the back of the shuttle box, the holes in the bracket
serving to carry, and guide the swell when forced outwards by the shuttle coming
in contact with its inner face, or inwards by the pressure of the blade spring.
When the swell is forced sufficiently far into the shuttle box by the blade spring, the
ends of the swell come in contact with the back of the shuttle box, and prevent
further movement of the swell, and the pins, or studs of the latter being moved out
of the carrying holes in the bracket.

page_text: Such being the nature and object of our invention the following is a complete
description of same, reference being made to the accompanying drawings forming a
part of this Specification in which :-
Fig. 1 is a view in elevation of the back of a shuttle box having our improvements
applied thereto.
Fig. 2 is a plan view of Fig. 1.
The several figs. on Sheet 2 are details drawn about full size.
According to this our said invention a slot 1 as ordinary, is formed in the back 2
of the shuttle box, and in this slot 1 the swell 3 is received, and works loosely
therein. The swell 3 is cast or formed with a lug or projection 4 at the back, and
also two or more (preferably two) pins or studs 5. 5. Against the lug or projection 4
bears, and presses one end 6 of a blade spring, the other end 7 being fixed by
screws 8.8 to the shuttle box, and the two studs or pins 5. 5 work freely through,
and in corresponding holes 9. 9 formed in the bracket 10 which is bolted or fixed
by screws to the back 2 of the shuttle box; the holes 9. 9 serving to carry, and
guide the pins or studs 5. 5 and the swell 3 when the latter is forced outwards or
backwards by the shuttle entering the box, and coming in contact with the inner
face of the swell 3; or when the latter is forced in an opposite direction, or inwards
by the pressure of the blade spring 6. 7. The lugs 11. 11 at the ends of the swell 3
come in contact with the back of the shuttle box and so prevent the blade spring 6. 7
forcing the swell 3 too far into the box, and the pins or studs 5. 5. being moved out
of their carrying holes 9. 9.
The screws 8.8 are for the purpose of holding the blade spring 6. 7 in position
and also adjusting the pressure of same on the swell 3.
In some cases the small pin 4" is received in a hole formed in the end 6 of the
blade spring and is for the purpose of steadying and partly holding the blade
spring 6 should one of the screws 8 become loose, or fall out, or the flanged
washer 5ª having a pin cast to it, the latter being held in a hole formed in the lug,
or projection 4, is employed and the blade spring 6. 7. is held between the flanges
of the washer the latter forming a broader bearing surface for the said spring.
The swell can readily be taken from the box by first removing the bracket 10
and can also be easily placed in new or existing looms.
At 12 is the shuttle box tongue, and 13 is the spring for controlling same.
The swell may be made of iron or other metal, or partly of metal, and partly of
other material, or wholly of a material other than metal such as leather, and is
made of various forms and sizes as may be thought desirable. Swells constructed
according to this our said invention have a rocking, or oscillating motion imparted
to them by the shuttle, as when the latter enters the box one end of the swell is
first depressed, or forced backwards, and as the shuttle gets further into the box
the swell rocks or oscillates in its bearings, and the whole length of the swell acts
on the shuttle more effectively than heretofore.
Having now particularly described and ascertained the nature and object of our
said invention, and in what manner the same is to be employed, we declare that
what we claim is :-
A swell mounted on studs, the latter received in a carrying bracket; the swell
moving or rocking on the studs, and the spring, or its equivalent all in combination,
and substantially as illustrated by the annexed drawings.
