Improvements in Shafts or Frames for Supporting Wire and other
Healds.
We, ARTHUR BERNOULLI BARLOW, Engineer, of the firm of H. B. Barlow and
Company, of Cornbrook Heald Works Manchester in the County of Lancaster, and
CHARLES JUMEAUX, Engineer, of the same place, do hereby declare the nature of
this Invention to be as follows:-
Our improvements are applicable to shafts or frames for supporting healds made
entirely of wire or inetal or of wire supported by knitted or other yarn loops and also
knitted healds.
In applying our Invention to a shaft for wire healds we dispenso with the fixed
hooks usually employed to support the metal rods.
To effect this we propose to make the shafts of sheet metal rolled or formed of
such configuration that the supports which carry the healds are free to slide in a
groove, recess, or space in the shafts this allows of a greater number of supports
than usual and consequently a much lighter metal rod wire or equivalent can be
use to support the healds a further advantage is that the ends of the healds are
protected by the sides of the aforesaid groove recess or space and a shallower
shaft can be made.
Our improved heald shaft can be employed for those wire healds which are supported
by yarn loops which have hitherto been passed over the shaft whereas the loops in our
case would he suspended from the inside of the metal shaft.
Our improvements as applied to wooden shafts for wire healds supported on yarn
loops or to knitted healds are intended to protect the yarn loops and this we accom-
plish by securing the rig band to which the loops are knitted to the interior or lower
side of the shaft in place of causing it to encircle the sides of the shaft as now
customary.
A convenient mode of effecting this is to cut a groove from end to end of the shaft
on the under side or to make the shaft in two portions cutting away a groove in which
the rig band is laid with a portion of the loops previous to socuring the two portions
of the shaft together to form a complete heall shaft; the rig band may be secured to
the shaft in any convenient manner.

Improvements in Shafts or Frames for Supporting Wire and other
Healds.
We, ARTHUR BERNOULLI BARLOW, Engineer, of the firm of H. B. Barlow and
Company, of Cornbrook Heald Works, Manchester, in the County of Lancaster, and
CHARLES JUMEAUX, Engineer, of the same place, 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 :—
Our improvements are applicable to shafts or frames for supporting healds made
entirely of wire or metal or of wire supported by knitted or other yarn loops and also
knitted healds.
In applying our invention to a shaft for wire healds we dispenso with the fixed hooks
usually employed to support the metal rods.
To effect this we propose to make the shafts of sheet metal rolled or formed of
such configuration that the supports which carry the healds are free to slide in a

page_text: groove, recess, or space in the shafts this allows of a greater number of supports
than usual and consequently a much lighter metal rod wire or equivalent can be
used to support the healds a further advantage is that the ends of the healds aro
protected by the sides of the aforesaid groove recess or space and a shallower shaft
can be made.
Our improved heald shaft can be employed for those wire healds which are sup-
ported by yarn loops which have hitherto been passed over the shaft whereas the loops
in our case would be suspended from the inside of the metal shaft.
Our improvements as applied to wooden shafts for wire healds supported on yarn
loops or to knitted healds are intended to protect the yarn loops and this we accom-
plish by securing the rig band to which the loops are knitted to the interior or lower
side of the shaft in place of causing it to encircle the sides of the shaft as now
customary.
A convenient mode of effecting this is to cut a groove from end to end of the shaft
on the underside or to make the shaft in two portions cutting away a groove in which
the rig band is laid with a portion of the loops previous to securing the two portions
of the shaft together to form a complete heald shaft; the rig band may be secured to
the shaft in any convenient manner.
And in order that our invention may be fully understood and readily carried into
effect wo will describe the accompanying Sheet of Drawings reference being had to
the figures and letters marked thereon.
Fig. 1 is a side view of part of a metal heall shaft made according to our invention
and Figs. 2 and 3 are transverse vertical sections of the same. Fig. 4 is a side view
partly in section of a portion of a wooden heald shaft also made according to our
invention and Fig. 5 is a soctional ond view of the same.
Referring first to Figs. 1, 2, and 3-a a¹ designate respectively the top and bottom
staves of a heald shaft each stave being made of metal rolled or otherwise formed to
support a wire or rod band links c the latter being threaded on the rod and of suitable
shape to support a second wire or rod d upon which the wire healds e are threaded or
strung; the two staves a a¹ are connected together at each end by pieces gas shown
in any convenient manner to complete the heald frame.
The chief advantages derived from this construction are first that the twisted ends e¹
of the healdse are thoroughly protected by the top grooved stave a and secondly as
the links which support the rods d and healds e are loose on the rods 6 the healds
and links can be readily moved along the rods d to suit any pitch of reed.
In place of metal links c links of any suitable material may be employed to support
the rods d and hoalds e. Again the rods 6 might be dispensed with and the
links c be formed with ball shaped heads to support them in the staves and instead
of applying our improvements to both the top and bottom staves as shown any
suitable equivalent for the bottom stave might be employed in combination with our
improved top stave a.
Figs. 4 and 5 represent a heald shaft in which the staves a a¹ are of wood,
grooved at a, b is a rig band on to which are knitted the yarn loops c through
which are passed a wire or rod b' and another rod d upon which are threaded or
strung the wire healds e a heald or two or more healds being placed between each
pair of loops. We place the rig band and rod 61 in the bottom of the groove a
and by means of pins or nails f secure the rig band and loops in the grooved
staves.
The staves a a¹ are connected together by steel end pieces 9 as in the previous
arrangement or in other convenient manner.
In place of making each stave a or a¹ of a single piece of timber as shown it may
be made of two or more pieces suitably connected together.
This improved shaft Figs. 4 and 5 may be used in conjunction with all classes of
knitted healds the rig bands and healds being supported as shown whereby the yarn
loops are effectually protected against the wear that takes place when the yarn is
passed over the staves in the ordinary manner.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1.-The method of constructing metal heald shafts and mounting the healds on
wires or rods carried by links so as to permit the healds and links to move or
be moved freely along the rods upon which they are threaded substantially as herein
described.
2.-A heald shaft the top and bottom staves or the top staves only of which are
grooved recessed or otherwise suitably formed to support movable links from which
wires or rods are suspended and upon which the healds are threaded substantially as
and for the purposes described with reference to Figs. 1, 2, 3.
3.- A grooved or recessed heald shaft arranged to support and protect the loops
which carry the rods on which the healds are strung substantially as described with
reference to Figs. 4 and 5.
4. Protecting the ends of knitted healds by supporting the rods or equivalents
which carry the rig bands in a grooved or recessed shaft substantially as and for the
purposes described.
