This invention relates to simple means of changing the order of succession in
which the healds are actuated in weaving, known as "shedding motion," by which
means a positive steady action in the upward and downward movement of the
healds or heddles is given allowing of working 3-4-5 or more shafts with
tappets besides considerably reducing the cost of "shedding motions."
For this purpose, I secure on the low shaft of the loom a bevil wheel which
actuates another bevil wheel secured on a cross shaft on which are fitted tappets
to work the "Healds or Heddles" and cach tappet is made with a surface plate on
which are cast projecting rims, leaving a space or groove between the rims forming a
guide in which works a rounded head of a lever connected to the treadle or a
small ball or friction pulley fitted and working on a stud secured in an arm of the
treadle lever and which through the revolving action of the tappet gives the
required up and down action to the treadle and the groove or guide holds the
treadle down until the shed is required to be made and the sheds are regulated by
the size of the tappets. The fulcrum of the treadle works on a stud fitted in a
frame made with guides; the end of the arm of the treadle near the tappet is
made with a half-moon to which is secured a band which takes the curve of the
lifting and lowering motion; the other end of the band is secured to the frame of
the heald.
To the other end of the treadle is also secured a band which is attached to a
half moon formed on the end of a jack lever, this lever works on a shaft fitted in
bearings of a frame which is fitted to the top rail of the loon; the other end of

page_text: the jack lever is also made with a half moon to which is secured a band also
secured to the top frame of the Heald; a second jack lever is employed in
connection with the first and working below the first, this second lever is made
longer than the top jack lever and works on a stud or shaft which works in
brackets bolted to the top rail of the loom, both ends of this jack lever are made
with half moons to which are attached bands, the band on the half moon on the
side of the treadle is attached to the end of the treadle lever; the other band is
secured to the top frame of the heald.
By these means a positive steady action is obtained either up or down in
working the "healds or heddles;" besides producing motions at a great reduction
in cost.

This invention relates to simple means of changing the order of succession in
which the healds are actuated in weaving, known as "Shedding motion" by which
means a positive steady action in the upward and downward movement of the
"healds or " heddles is given, allowing of working three, four, five or more
shafts with tappets, besides considerably reducing the cost of "Shedding motions."
For this purpose I secure on the low shaft of the loom a bevil wheel which
actuates another bevil wheel secured on a cross shaft on which are fitted tappets to
work. the "healds" or "heddles" and each tappet is made with a surface plate on
which are cast projecting rims, leaving a space or groove between the rims forming.
a guide in which works a small ball or friction pulley fitted and working on a stud
secured in an arm of the treadle lever and which through the revolving action of
the tappet gives the required up and down action to the treadle and the groove or
guide holds the treadle down until the shed is required to be made and the sheds
are regulated by the size of the tappets. The fulcrum of the treadle works on a
stud fitted in a frame; the end of the arm of the treadle near the tappet is made
with a half moon to which is secured a band which takes the curve of the lifting
and lowering motion; the other end of the band is secured to the frame of the
heald.
To the other end of the treadle is secured a band which passes over pullies
working on studs secured to the top rail of the loom, the bands are attached to the
healds. By these means a positive steady action is obtained either up or down in
working the "Healds" or Heddles;" besides producing motions at a great
reduction in cost.
"
But in order to enable my improvements to be better understood, I will
proceed to describe the same by reference to the accompanying drawing in which
figure 1, represents a front view of my arrangement of apparatus for changing the
order of succession in which the healds are actuated in weaving and figure 2 is a
plan of the same.
Similar letters of reference in both figures are used to represent similar parts.
On the low shaft A, of the loom I secure a bevil wheel B, which actuates
another bevil wheel C, secured on the cross shaft D; I also secure on the shaft A,
another bevil wheel B₁, for reversing the motion and so as to bring the bevil
wheel A, out of gear with the bevil wheel C, and bring in gear the bevil wheel B¹;
the bevil wheels are kept in position by the set screws E,
On the cross shaft D, are fitted tappets F, to work the "healds" or "heddles" G,
and each tappet is made with a surface plate H, having projecting rims I, between
which is a space or groove J, forming guides in which works a small ball or
friction pulley K, working on a stud secured in the arm L, of the treadle lever M ;
the friction pulley K, by the revolving action of the tappet F, gives the required
up and down action to the treadle and the groove J, holds the treadle down until
the shed is required to be made and the sheds are regulated by the size of the
tappets. The fulcrum of the treadle works on a shaft N, fitted in a support O,
cast on frames P, secured to the loom; the arm L, is made with a half moon Q, to
which is secured a band R, which takes the curve of the lifting and lowering
motion; the band is secured to other bands R¹, attached to the frame S, of the
heald or heddle G.

page_text: To the arm T, of the treadle lever M, is secured a band U, which is attached to
the bands V, passing over pullies W, working on studs secured to the top rail Y, of
the loom; these bands are secured to the top frame X, of the healds or heddles.
.a
The up and down action of the treadles works the healds or heddles giving a
positive steady action in their upward and downward movement by which means
I am able to work three, four, five or more shafts with tappets.
Having thus described my improvements and the best means I am acquainted
with for carrying the same into effect, I would have it understood that what I
claim is :-
1
Firstly. The combination of parts forming the improved apparatus for changing
the order of succession in which the healds or heddles are actuated in weaving
whereby a positive steady action in the upward and downward movement of
the healds or heddles is given, allowing of working three, four, five or more
shafts with tappets, substantially in the manner and for the purposes herein before
described and illustrated in the accompanying drawing or any mere modifications
thereof.
Secondly. The construction and employment of the improved apparatus for
changing the order of succession in which the healds or heddles are actuated
in weaving, substantially as hereinbefore described and represented in the
accompanying drawing:
In Witness whereof I the said James Stansfield, have hereto set my hand
and seal this eighteenth day of September in the year of our Lord one
thousand eight hundred and eighty two.
