We ENOCH OPENSHAW TAYLOR, Machine Maker and Ironfounder, and DAVID
KENYON, Machine Fitter, both of Marsden Iron Works, Marsden, in the County of
York, do hereby declare the nature of our said invention for "IMPROVEMENTS
IN APPARATUS FOR OPERATING THE HEALDS OF LOOMS FOR WEAVING," to be as
follows
-
This invention 18 designed, to impart a positive lifting, and lowering, and locking
of the heald levers and healds.
We drive continuously, by a train of wheels from the crank shaft, or other going
part of the loom, a barrel wheel, toothed on the main part of ita circumference, the
said wheel is enclosed, by a series of elongated horizontal, eyed or looped levers,
having teeth on their upper and lower inner edges, the terminating arm or end of
each lever forms a rack, and gears with a pinion wheel, which operates the arm of
a lever, connected with the upper, and lower beald staves, there being a large tooth
or pin, on the pinion, which engages with a slot or recess, formed in part of the end
of the said lever, the other part of the end of the lever is crescent or concave
A chain of tappets, or other peg, or pattern mechanism, 18 under the toothed
loops, of the levers referred to, and when a tappet or peg lifts, one of the levers, its
teeth engage with the teeth of the barrel wheel, and the lever will thereby be
drawn outwards, so operating the pinion, levers, and healds, so likewise when a
blank occurs in the pattern mechanism, the loop will descend, causing the teeth of
its upper edge, to gear with the pinion and the looped lever, pinion, and heald
levers, will be moved in the opposite direction, the crescent or concave ends of the
levers, when the latter are operated, close upon a rim or boss, of the pinion, and
lock the levers, and healds, firmly until another change is indicated and necessary.

We ENOCH OPENSHAW TAYLOR, Machine Maker and Ironfounder, and DAVID
KENYON Machine Fitter, both of Marsden Iron Works, Marsden, in the County of
York, do hereby declare the nature of our said invention for "IMPROVEMENTS IN
APPARATUS FOR OPERATING THE HRALDS OF 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
1
This invention is designed to impart a positive lifting and lowering and locking
of the heald levers and healds.
Such being the nature and object of this our said invention, the following is a
complete description of same, reference being had to the accompanying drawings
forming a part of this specification, in which
Fig 1 is a front elevation of part of a loom having our improvements applied,
part of this view being illustrated on Sheet Number 2
Fig 2 is an end elevation.
The several views on Sheet 3 are details or parts detached
We drive from the crank shaft 1 by a train of spur wheels 2, 3, 4, 5, the bevel
wheel 6, fast on the shaft 7-The wheel 8 18 loose on the shaft 9, but the wheel 10 is
fast on the said shaft 9,-between the wheels 8, 10, 18 the clutch box 11-the shaft 9
18 the axis of the toothed barrel 12 having teeth on the main part of its circum-
ference the wheel 12 is enclosed by a series of elongated horizontal eyed or looped
levers 13 having teeth 14, 15, on their upper and lower inner edges, the terminating
aim or end of each lever forms a rack 16 and gears with a pinion wheel 17 which
operates the arm of the heald lever 18 connected with the upper and lower heald
staves by means of the jack levers 19 and connections as clearly shewn, partly on
Sheet 1 and partly on Sheet 2-The wheel 17 operates the jack lever 18 by means
of the pin 20 which engages with the slot or recess 21 formed in part of the end of
the said lever, the other part of the end of the lever 18 likewise crescent or concave
BO as to fit to the disc or flange 22 in the wheel 17-and thus lock and steady the
heald levers in their raised or lower position-The Jack levers 18 being moved o
rocked on their axial pin 23 up and down by the pin 20 engaging with the slot 21
as often and accordingly to the direction of movement of the rack 16 which will
give motion to the pinion 17 and consequently the pin 20 first in one direction then
In the other-24 are friction runners in which the rack 16 slides-At 25 are a
chain of tappets or other peg or pattern mechanism under the toothed loops of the
levers 13 and when a tappet or peg lifts one of the levers 13 as shewn in the
drawing Fig 1, the lower teeth of the lever 13 engage with the teeth of the barrel
wheel 12 and the lever 13 will be drawn outwards to the right hand whereon the
rack 16 would operate the wheel 17, pin 20, and Jack lever 18 the pin 20 will
engage with the slot 21 and operate the lever 18, and effect a change in the shed so
likewise when a blank occurs in the pattern mechanism 25 that is to say when the
underside of the lever 13 rests upon two of the bowls 25, the lever 13 would be

page_text: lowered and its upper teeth 14 would engage with the teeth of the wheel 12 and
the said lever and its rack 16 would thereon move inward or to the left hand
causing a corresponding change in the healds and shed-The levers 13 when at the
extremity of their motion are steadied and locked in such position by the bowls 26
on the spring needles 27 entering the recesses 28
When it is desired to level the healds the handle 29 will be employed for turning
the shaft 30 and eccentrics 31 thereon so as to place all the levers 13 with their
lower teeth in gear with the wheel 12 and by means of the hand wheel 32, see
Fig 2, all the racks and healds may be moved to one position-The peg wheel 33
and star wheel 34 moving the pattern mechanism 25 in like ratio so as to preserve
correct relative positions so likewise when it is desirable to reverse the motion for
purpose of letting back for removal of float or imperfection of weaving, the clutch
box 11, Fig 2, will be thrown into gear with the wheel 8 thereby reversing the
motion of all the parts.
The details on sheet 3 illustrate the differences in concave ends of levers 18 and
of the disc or flange 22 necessary to give the varying amount of motion to the
Beveral heald staves in forming the shed also separate view is given of the shaft 30
on which are the eccentrics 31 for levelling the levers 18 there being on such shaft
flanges 32 which space the several levers 13, the shaft 30 is free to move or rock by
the handle 29, and the two eccentrics 35 which are fixed in the part of the frame 36,
carry or support the said shaft 80
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 13
The looped toothed rack levers 13, 16, wheels 17, pin and disc 20, 22, Jack
levers 18, 19, and healds all in combination and arranged substantially as illustrated
and herein fully described
