Improvements in Mounting Wire or Metal Healds for Weaving
and in the Heald Shafts or Frames.
We, HENRY BERNOULLI BARLOW, of 17 St. Anns Square, Manchester in the
County of Lancaster, Consulting Engineer and ARTHUR BERNOULLI BARLOW, of
Cornbrook Heald Works, Cornbrook, Manchester aforesaid, Wire Heald Manu-
facturer, do hereby declare the nature of said Invention for lMPROVEMENTS IN
MOUNTING WIRE OR METAL HEALDS FOR WEAVING AND IN THE HEALD SHAFTS OR
FRAMES, to be as follows:
-
Our invention relates to wire or metal healds which are threaded on metal rods
connected to the shafts or frames the chief object of our Invention being to dispense
with the hooks which are usually employed to sustain the said rods or supports.
In carrying out our Invention the shafts or staves employed may be independent
pieces of timber such as are commonly used for knitted yarn healds or they may be
connected together by end pieces to form a frame as generally employed for Barlow's
Patent Wire Healds but we employ different means from those now in use for
sustaining the longitudinal metal rods or other supports on which the wire or metal
healds are threaded.
"
According to our Invention we knit twine in continuous loops of equal lengths
which surround the shafts or staves or the top stave only and are knitted on a
rig band
any desired number to the inch in the manner well known in heald
knitting. The metal rods which we prefer to make round and of small diameter are
passed through these loops and are also passed through the holes or loops in the ends
of the metal healds one or other number of healds being placed between the adjoining
loops on both the top and bottom staves.
In place of twine other suitable material may be used for the loops or we may use
fine wire coiled around one or both of the staves to support the rods; when fine wire
is used with wooden or metal staves we propose to wrap it tightly round a longitudinal
wire or rod between each loop to bind the whole together; the wire may lie in a
groove made along the shaft to receive it.
Another part of our Invention consists in making the shafts of metal preferably

page_text: hollow whereby the frames i.e. the shafts and healds can be made of the same depth
as with knitted healds of the ordinary kind.
With the metal shafts we use a "rig band" with twine loops to support the metal
or other rods or if wire coils are used we may solder them to the shaft.
We form the hooks for the jack cords of a piece or pieces of wire which pass over
the outside of the shafts and are turned into the hollow shaft at each end.
We are well aware that there is no. novelty in the use of cord or twine loops
connected to a "rig band" with each loop passed through an eye or hole in the metal
heald to connect the healds to the top and bottom heald, shafts also a wire cord or
other pliable band has been passed from end to end of the shafts through the top and
bottom eyes or holes in each heald the above arrangement being fully described in the
Specification to Letters Patent No. 583 of 1872 granted to Samuel Yeadon.
In our present Invention we thread the metal healds on and support them entirely
by rods or other longitudinal supports as now customary but instead of employing
hooks we use the "rig band" with loops or the other means hereinbefore set forth to
carry the rods or other longitudinal supports. The end eyes of the metal healds
may be large enough to allow them to be moved up and down on their longitudinal
supports or they may be simply an easy fit in which case the supports would move
with the healds.
One feature of our Invention consists in making the wooden or metal shafts slightly
wedge shaped in section thickest at the outside by this means the continuous loops or
coils move more freely when the healds are pushed sideways when taking up an end
or warp thread.
Our improvements are applicable to wire or metal healds for weaving ordinary
goods as well as carpets belting and the like.

We, HENRY BERNOULLI BARLOW of 17 St. Anns Square Manchester in the
County of Lancaster Consulting Engineer and ARTHUR BERNOULLI BARLOW of
Cornbrook Heald Works Cornbrook Manchester aforesaid Wire Heald Manu-
facturer, do hereby declare the nature of said Invention for IMPROVEMENTS IN
MOUNTING WIRE OR METAL HEALDS FOR WEAVING AND IN THE HEALD SHAFTS OR
FRAMES, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
Our invention relates to wire or metal healds which are threaded on metal rods
connected to the shafts or frames the chief object of our Invention being to dispense
with the hooks which are usually employed to sustain the said rods or supports.
In carrying out our Invention the shafts or staves employed may be independent
pieces of timber such as are commonly used for knitted yarn healds or they may be
connected together by end pieces to form a frame as generally employed for Barlow's
Patent Wire Healds but we, employ different means from those now in use for
sustaining the longitudinal metal rods or other supports on which the wire or metal
healds are threaded.
<C
According to our Invention we knit twine in continuous loops of equal lengths
which surround the shafts or staves or the top stave only and are knitted on a
rig band"
any desired number to the inch in the manner well known in heald
knitting. The metal rods which we prefer to make round and of small diameter are
passed through these loops and are also passed through the holes or loops in the ends
of the metal healds one or other number of healds being placed between the
adjoining loops on both the top and bottom staves.
In place of twine other suitable material may be used for the loops or we may
use ine wire coiled around one or both of the staves to support the rods when fine
wire is used with wooden or metal staves we propose to wrap it tightly round a longi-
tudinal wire or rod between each loop to bind the whole together; the wire may lie
in a groove made along the shaft to receive it.
"
Another part of our Invention consists in making the shafts of metal preferably
hollow whereby the frames i.e. the shafts and healds can be made of the same depth
as with knitted healds of the ordinary kind. With the metal shafts we use a
rig band" with twine loops to support the metal or other rods or if wire coils are
used we may solder them to the shaft. We form the hooks for the jack cords of a
piece or pieces of wire which pass over the outside of the shafts and are turned in to
the hollow shaft at each end.
[i
We are well aware that there is no novelty in the use of cord or twine loops
connected to a rig band" with each loop passed through an eye or hole in the
metal heald to connect the healds to the top and botton heald shafts; also a wire

page_text: cord or other pliable hand has been passed from end to end of the shafts through the
top and bottom eyes or holes in each heald the above arrangement being fully
described in the Specification to Letters Patent No. 583 A.D. 1872 granted to
Samuel Yeadon.
In our present Invention we thread the metal healds on and support them entirely
by rods or other longitudinal supports as now customary but instead of employing
hooks we use the "rig band" and with loops or the other means hereinbefore set
forth to carry the rods or other longitudinal supports. The end eyes of the metal
healds may be large enough to allow them to be moved up.and down on their longi-
tudinal supports or they.may be simply an easy fit in which case the supports would
move with the healds.
One feature of our Invention consists in making the wooden or metal shafts slightly
wedge shaped in section thickest at the outside by this means the continuous loops or
coils move more freely when the healds are pushed sideways when taking up an end
or warp thread.
Our improvements are applicable to wire or metal healds for weaving ordinary
goods as well as carpets belting and the like.
And in order that our Invention may be fully understood and readily carried into
effect we will describe the accompanying Sheet of Drawings reference being had to
the figures and letters marked thereon.
Figures 1, 3 and 5 are side elevations of parts of heald frames to which our
Improvements are applied and
Figures 2, 4 and 6 are transverse vertical sections of the same.
In Figs. 1 and 2-a a designate the top and bottom wood staves or shafts which are
connected together by metal end pieces a¹ to form the heald frame. The continuous
loops of twine or other suitable material pass round the shafts a rigband e and
rods d. The rods d are passed through loops or eyes at the ends of the wire healds e
as well as through the loops 6 and they may also be passed through the end piece a¹ of
the frame or not as required.
In Figs. 3 and 4.- fare the top and bottom staves in this case made of sheet
metal bent as shown and f" is one of the end pieces of the heald frame; gg are wires
coiled continuously one round each stave and rod d; h is a wire which extends
along the stave and is turned in at the ends and on this wire are hooks i for the jack
cords; or the wire h may be bent to form hooks for the jack cords; j is a jack cord
hook turned in at the end of the lower stave f. The wire coil g is soldered all along
or at intervals to the staves preferably at points furthest from the rods d so as
to allow the healds e to be moved apart latterally when required piece a warp end.
In Figs. 5 and 6-k is the top stave of the frame made of wood slightly tapered
or wedge shaped; k is one of the metal end pieces of the frame; 1 are the continuous
loops preferably of wire which support the rods d the wire of the loops is wound
round a pitch rod m once twice or more times. between each loop in order to secure
the wire in position and to keep the loops any desired distance apart; nare the healds
made with mails n'. The lower part of the frame and healds are not shown in these
views.
When the heald frames are made without end pieces the rods d are bent or washers
and rings or equivalent means used to keep the healds on the rods.
Although in Figs. 1 and 2 we have shown one heald only between each pair of
loops and in Figs. 3 and 4 two healds between each pair of coils of the wire g it is
obvious that any desired number of healds may be placed between the loops or coils
and in place of wire coils as described twine loops can be used in conjunction with
metal staves.
The construction of heald frame indicated in Figs. 5 and 6 may have staves of
sheet or har metal in place of wood as shown.
In applying our Invention to "spaced" healds for weaving striped fabrics we knit
the continuous loops in the positions required on the rig band or we knit them along
the whole band and then divide the loops into sections of any desired number these
sections of loops are then secured to the shafts in any convenient manner and in the

page_text: desired position. The rods which are supported by the loops and carry the healds
may extend the whole length of the shafts or be in short lengths to suit the sections of
the knitted loops.
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. Supporting the rods on which the wire or metal healds are strung by loops of
twine or other suitable material connected to rig bands one or other number of healds
being placed on the rods in each space between the loops whereby any given number
of healds to the inch may be retained in their places on the rods substantially in the
manner and for the purposes specified.
2. The combination with a metal heald shaft of a coil g and rod d for 'spacing'
and carrying the wire or metal healds as herein described and as shown on Figs. 3
and 4.
3. The combination with metal heald shafts of a wire or wires for the jack
cords said wires being secured to the shaft substantially as shown in Figs. 3 and 4.
4. Supporting the rods on which the healds are threaded by wires lapped round
pitch rods and also formed into loops one or other number of healds being placed in
each space between the loops as and for the purposes herein set forth and as shown on
Figs. 5 and 6.
