Heddles of Looms for Weaving.
We, RICHARD LONGDEN HATTERSLEY, of North Brook Works, Keighley, in the
County of York, Machine Maker, and SIMEON JACKSON, of the same address,
Manager, do hereby declare the nature of this invention to be as follows:-
The first part of our invention relates to that class of loom known as the rising
box loom, which has a tier of compartments or shuttle boxes, consisting of two or
more, at one or both ends of its slayboard, and the motion imparted to these boxes
is so arranged that any one of them may be brought level with the slayboard at
any predetermined moment.
Our invention consists of an arrangement of levers, adapted to operate 6 boxes
at one or both sides of the loom. In order to carry out the same, we make use of
the well-known continuously rotating toothed segments, which operate, by means
of toothed crank wheels, the before-mentioned levers. The latter, which comprise
our invention, consist of three simple levers, having an arm on each side of their
fulcrums, and they are combined or compounded in such a manner that, when
operated, two of these levers move the tier of boxes a distance equal to two boxes
respectively, and one a distance equal to one box. From this it will be seen that
by operating 1 or 2 or 3 of the simple levers together, any one of the six boxes can
be brought level with the slayboard at one operation.
When a tier of boxes is necessary at both ends of the slayboard, two of these
combinations can be applied.
The second part of our invention relates to an improvement in the well-known
Keighley or Hattersley's dobby.
The usual method of attaching the balk lever to the bell crank lever in this
dobby is by means of a small circular projection attached to the bell crank lever,
on which the balk lever is loosely mounted.
This projection has hitherto been attached at right angles to the bell crank lever,
but in this, our improvement, we design the same so that it forms an obtuse angle
with the said bell crank lever.
By this means, we obtain more bearing surface on the pulling or drawing side
of the said projection, also the balk is more securely attached.
Dated this 11th day of October 1897.

We, RICHARD LONGDEN HATTERSLEY, of North Brook Works, Keighley, in the
County of York, Machine Maker, and SIMEON JACKSON, of the same address,
Manager, 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:-
The first part of our invention relates to that class of loom known as the rising
box loom, which has a tier of compartments, or shuttle boxes, consisting of two or
more, at one or both ends of its slayboard, and the motion imparted to these boxes
is so arranged that any one of them may be brought level with the slayboard at
any predetermined moment.
Our invention consists of an arrangement of levers adapted to operate 6 boxes
at one or both sides of the loom. In order to carry out the same, we make use of
the well-known continuously rotating toothed segments, which operate, by means
of toothed crank wheels the before-mentioned levers. The latter, which comprise
our invention, consist of three simple levers, having an arm on each side of their
fulcrums, and they are combined or compounded in such a manner that, when
operated, two of these levers move the tier of boxes a distance equal to two boxes
respectively, and one a distance equal to one box. From this it will be seen that
by operating or 2 or 3 of the simple levers together any one of the G boxes can
be brought level with the slayboard at one operation.
When a tier of boxes is necessary at both ends of the slayboard, two of these
combinations can be applied.
The second part of our invention relates to an improvement in the well-known
Keighley or Hattersley's dobby.
The usual method of attaching the balk lever to the bell crank lever in this
dobby is by means of a small circular projection attached to the bell crank lever,
on which the balk lever is loosely mounted.
This projection has hitherto been attached at right angles to the bell crank lever,
but in this, our invention, we design the same so that it forms an obtuse angle
with the said bell crank lever.
By this means, we obtain more hearing surface on the pulling or drawing side
of the said projection, also the balk is more securely attached.
In order to explain more clearly our invention, we append hereto three sheets
of drawings marked with letters and figures of reference, in which like letters and
figures denote like parts.
Fig. 1 shows an end elevation of the box motion. Fig. 2 a plan view of same.
Figs. 3, 4, 5, 6, & 7 views hereinafter referred to. Fig. 8 an elevation of bell
crank lever and balk lever. Fig. 9 a section of same and Fig. 10 an enlarged
section of same
As already mentioned the first part of our invention consists of three simple
levers A, A & A³ fulcrumed respectively on the studs A, A, A and operated in
the ordinary manner by means of the well-known toothed segments and crank
wheels, being connected with same by the rods A7, A8, AD, see Figs. 1 & 2, as shown
hereafter, they are combined so that the tier of shuttle boxes A10, to which they are
connected by means of the rod A" and stud A can be raised or lowered a distance
equal to 1, 2, 3, 4 or 5 shuttle boxes at one operation as required.
The position of the levers A1, A³ & A³, when all the six boxes are raised, is shown
by Figs. 1 & 2.

page_text: Fig. 3 shows 5 boxes raised, the lever A being operated thus lowering the
boxes a distance equal to one box by changing the position of the stud A'.
Fig. 4 shows 4 boxes raised, the lever A being operated and thus lowering two
boxes.
Fig. 5 shows three boxes raised, the levers A & A³ are operated thus changing
the position of the two studs A & A and lowering 3 boxes.
In Fig. 6 two levers A & A are operated and a change of 4 boxes is made.
In Fig. 7 all the levers A', A & A are operated, thus making the full change
of 5 boxes.
It will be seen from the above that the lever A makes a change of two boxes,
and the lever A2, one box, and the lever A two boxes, the lever A2 and one of the
levers A & A together 3 boxes, the levers A & A together 4 boxes and all the
levers together 5 boxes.
With reference to the second part of our invention, the bell crank lever B, balk
lever B, catches 12 & 13, knives B & B are all of the well-known construction,
except the connection between the levers B & B. It will be seen from Figs. 8,
9 & 10 that the projection B which connects the lever 13 with the lever Bis
designed at an angle with the bell crank lever B, not as hitherto at a right angle
but in such a manner that there is more bearing surface on the drawing side. Also
the balk is more securely attached.
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 :-
1st. The construction and combination of the levers for box motion as shown
and described.
2nd. The construction of the projection B on the bell crank lever B for the
purpose specified.
