IMPROVEMENTS IN SHUTTLES AND PICKERS TO BE EMPLOYED IN LOOMS FOR WEAVING
Year: 1884

page_text: I WILLIAM DAWSON of 12 Clifton Street Burnley in the county of Lancaster
Shuttle Maker do hereby declare the nature of my Invention for IMPROVEMENTS
IN SHUTTLES AND PICKERS TO BE EMPLOYED IN LOOMS FOR WEAVING, to be as
follows:-
The object of my invention is to construct pickers and shuttles more durable and
less liable to be damaged or get out of order than as at present constructed.
The tongue of the shuttle is pivotted and has a heel which acts as a stop against
the wood part of the shuttle which may have a button headed screw (to prevent
looseness or play) to abut against a corresponding recess in the heel of the tongue,
this screw will adjust the position of the tongue a blade spring bears upon a
projection above the pivot of the tongue, when the tongue is raised to take off the
cop or bobbin, the spring passes into a nick in the tongue above the pivot or a
conical projection may be formed on the heel of the tongue, which abuts in a recess
in the wood of the shuttle when the tongue only requires partly raising a nick is
formed which comes against the spring end and so prevents it being raised too far.
In shuttles for calico weaving the tongue is formed with a spring with one or
more projections to assist in keeping on the bobbin or cop, between the spring and
the tongue is a second strip of metal with a corresponding projection which when
in position in the shuttle raises or swells out the spring of the tongue and so holds
tight the bobbin or cop on raising the tongue to take off or put on a bobbin or cop,
the middle strip is drawn back and the cop or bobbin, can be readily taken out.
The spring acting on the heel of the tongue is held by a metal screw passing into a
brass bush or nut.
The shuttle points or tangs I make with recesses or grooves at opposite sides of
the points of the shuttle and corresponding projections or pegs are made or fixed
upon each side of the picker where the shuttle strikes, made of the same substance
as the picker, which may be of wood the projections, or pegs are renewable when
destroyed, and prevent the shuttle from destroying the picker.

page_text: COMPLETE SPECIFICATION.
I WILLIAM DAWSON of Burnley in the county of Lancaster Shuttle Maker do
hereby declare the nature of my said Invention for "IMPROVEMENTS IN SHUTTLES
AND PICKERS TO BE EMPLOYED IN LOOMS FOR WEAVING," and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
The object of my invention is to construct pickers and shuttles, more durable,
and less liable to be damaged or get out of order, than as at present constructed.
The tongue of the shuttle is pivotted and has a heel, which acts as a stop against
the wood part of the shuttle, which may have a button headed screw, (to prevent
.looseness or play) to abut, against a corresponding recess in the heel of the tongue,
this screw will adjust the position of the tongue, a blade spring bears upon a
projection above the pivot of the tongue, when the tongue is raised to take off the
cop or bobbin, the spring passes into a nick in the tongue above the pivot; or a
conical projection may be formed on the heel of the tongue, which abuts in a recess
in the wood of the shuttle, when the tongue only requires partly raising, a nick is
formed which comes against the spring end and so prevents its being raised too
far; heretofore in shuttles for woollen looms, a pin has been put through the
shuttle to prevent the peg, from being raised too far, this pin continually splits the
shuttle, by my arrangement this is entirely avoided.
In shuttles for calico weaving the tongue is formed with a spring with two or
more projections, to assist in keeping on the bobbin or cop, between the spring and
the tongue, I place a second strip of metal, with a corresponding projection, which
when in position in the shuttle in the shuttle, raises or swells out the spring of the
tongue, and so holds tight the bobbin or cop, but on raising the tongue on its
pivot, to take off or put on a bobbin or cop, the small strip is pushed back, and the
cop or bobbin can be readily taken out.
The spring acting on the heel of the tongue is held by a metal screw, passing
into a metal bush or nut.
The shuttle points or tangs I make with recesses or grooves at opposite sides of
the points of the shuttle, and corresponding projections or pegs, are made or fixed
upon each side of the picker, where the picker strikes, made of the same substance
as the picker, which may be of wood; the projections or pegs are removable when
destroyed, and prevent the shuttle destroying the picker.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation in section of part of shuttle with my improvements
attached.
!.
Figs 2, 3, 4 and 44, are modifications of Fig. 1.
Figs 5 and 6 shew elevation in section and plan of part of shuttle for calico
weaving, also my improved shuttle tang, recess, and pegs in picker.
At Figs 1 and 2 the tongue or peg A, of the shuttle is pivotted at B, and has a
heel C, which acts as a stop, against the wood part D, of the shuttle, which may
have a button headed screw E, (to prevent looseness or play) to abut against a
corresponding recess F, in the heel C, of the tongue, this screw will adjust the
position of the tongue, or the button headed screw, may be in the heel of the
tongue, and the recess in the wood of the shuttle, (see Fig. 3) a blade spring G bears
upon a projection H, above the pivot of the tongue, when the tongue is raised to
take off the cop or bobbin, the spring passes into a nick J, in the tongue above the

page_text: pivot; or a conical projection E', may be formed on the heel of the tongue, (see
Fig 4) which abuts in a recess in the wood of the shuttle, when the tongue only
requires partly raising, a nick J¹ is formed, which comes against the spring end, and
so prevents its being raised too far; heretofore in shuttles for woollen looms a pin
has been put through the shuttle to prevent the peg from being raised too far, this
pin continually splits the shuttle, by my arrangement this is entirely avoided.
In shuttles for calico weaving (see Figs 5 and 6) the tongue is formed with a
spring K, with two or more projections to assist in keeping on the bobbin or cop,
between the spring K and the tongue, I place a second strip of metal L, with a
corresponding projection M, which when in position in the shuttle raises or swells
out the spring of the tongue by coming in contact with the projection N, and so
holds tight the bobbin or cop, but on raising the tongue on its pivot to take off or
put on a bobbin or cop, the small strip L, is pushed back, and the cop or bobbin
can be readily taken out.
The spring G, acting on the heel of the tongue is held by a metal screw P,
passing into a metal bush or nut R.
The shuttle points or tangs, (see Figs 5 and 6) I make with recesses or grooves S,
at the opposite sides of the points of the shuttle, and corresponding projections, or
pegs T, are made or fixed upon each side of the picker, where the picker strikes,
made of the same substance as the picker, which may be of wood, or buffalo hide,
the projections or pegs, are removable when destroyed, and prevent the shuttle,
destroying the picker.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I would have it
understood that I do not claim the use of an elongated heel to the shuttle pegs, as
it is old and well known but I declare that what I claim is:-
1 The adjustable conical or button head, in connection with the heel of shuttle
pegs, the recess being either in the wood of the shuttle or in the heel as shewn and
described in the various drawings.
2 The conical or button head non adjustable, in connection with the heel of the
shuttle peg as shewn and described.
3 The shuttle peg constructed with a nick or recess engaging with the end of
the spring, and so preventing the strain upon the wood of the shuttle as shewn
and described.
4 The screw for the spring screwing into the metal bush (instead of into the
wood of the shuttle) as shewn and described.
5 The shuttle tangs or tips recessed or grooved, and fitting onto projecting guide
pegs, on the pickers as shewn and described.
6 In shuttle for calico weaving the extra strip of metal coming in contact with
the projection N, and holding tight the bobbin or cop, as shewn and described.
Dated this seventh day of November 1884.
