"IMPROVEMENTS IN LOOMS FOR WEAVING."
This invention has for its object improved apparatus for working the healds
whereby a considerable saving is effected in the making and working the loom by
reason of my improvements enabling the numerous levers Jack levers top cross
rails and rods for working the healds (as heretofore) being dispensed with..

In the construction of mechanism for working the healds according to this my
invention I employ metal healds composed of steel strips the lower portions of
which are connected to a heald stave or cross bar the latter being connected with
levers and screw adjustment whereby the position of the said levers in relation to
tappet or scroll plates employed for operating the levers and healds is determined
and regulated-The metal strips composing the healds are provided with zig zag
eye so that all the strips are side by side and their edges being opposite the weaver
and in front of the loom and being open and unattached at their upper ends afford
great facility convenience and light to the weaver for separating the healds for
piecing up a broken end or warp thread or for other purpose.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said David Eastwood in the Great Seal Patent Office on the 14th June
1883.

'IMPROVEMENTS IN LOOMS FOR WEAVING"
This invention has for its object improved apparatus for working the healds
whereby a considerable saving is effected in the making and working the loom by
reason of my improvements enabling the numerous levers, jack levers, top cross
rails, and rods for working the healds (as heretofore) being dispensed with
In the construction of mechanism for working the healds according to this my
invention I employ metal healds composed of steel strips the lower portion of
which are connected to a heald stave or cross bar the latter being connected with
levers and screw adjustment whereby the position of the said levers in relation to
tappet or scroll plates employed for operating the levers and healds is determined
and regulated The metal strips composing the healds are provided with zig zag
eye so that all the strips are side by side and their edges being opposite the weaver
and in front of the loom and being open and unattached at their upper ends afford
great facility convenience and light to the weaver for separating the healds for
piecing up a broken end or warp thread or for other purpose.
Such being the nature and object of this my said invention I will now proceed
to describe the same in detail and in order that the invention may be fully
understood I have hereunto annexed a sheet of drawings illustrative thereof in
'which at
Fig 1 is a front elevation of healds and apparatus for operating the same, about
one third full size
Fig. 2 is end elevation of same drawn about one third full size-The other
figures about full size being of separate parts or details
At 1 are the metal healds of steel by preference afterwards hardened and
tempered, 2 a metal heald stave passed through the slot 3-the healds have zig zag
eyes as shewn at 4 the staves 2 are connected to the T lever 5 by means of the
bolts 6 which are split lengthwise to the point 7 in order to admit the introduction
of the stave 2 the said bolts 6 are chased or screwed so as by the nut 8. 8 to secure
the staves. in position the bolts 6 are then by means of the nuts 9. 10. 11 secured
to the T lever 5. the lower arm 12 of which is by pin 13 connected to the tappet
lever 14. 15 is the tappet for actuating the levers and healds
It will be seen the bolts 6 are of sufficient length as to permit of the adjusting
the position of healds and their operating levers in relation to the tappets and that
the heads are steadied in position by means of the warp, threads passed through
the eyes 4 there being no upper heald staves required, consequently the jack levers
top cross rail connecting rods are dispensed with.
The healds 1 being free at their upper ends afford great facility to the weaver
for separating the healds for purpose of piecing up a broken end or warp
thread. There being no overhead top cross rail or other connection the light is
unobstructed.
Having thus fully described the nature and particulars of this my said invention
together with the manner in which the same is to be or may be performed or
carried into practical effect I would have it understood that what I claim as my
invention is
Firstly. The use in combination of the healds open at their upper ends, connecting,

and illustrated
Secondly. The use of open end healds combined with levers and tappets or
eccentrics for operating the same as described herein.
In Witness whereof I the said David Eastwood have hereunto set my hand
and seal this ninth day of June in the year of our Lord one thousand
eight hundred and eighty three
