"
I, JOHN EDWARD WADSWORTH, of 530 Oldham Road, Manchester, Mechanic, do
hereby declare the nature of my invention for IMPROVEMENTS IN INDEX
MACHINES OR DOBBIES EMPLOYED IN LOOMS FOR WEAVING," to be as follows:-
The improvements relate to what are known as Index Machines or Dobbies
which are a modified form of Jaquard Machines employed in Looms for Weaving;
and the said improvements consist of peculiar arrangements for actuating the
hooks of such machines, whereby the ordinary cross wires with loops and their
springs are dispensed with.
To accomplish this and to effect my improvements, I form the hooks of sufficient
length to allow of a folded or looped end which when fitted in a slide constitutes a
spring action as is well understood. In front of the row of hooks for the purpose
of actuating the same, I fix a case or box, or it may be a block, which is perforated
at the requisite distances, in which perforations headed pins are placed, very like
unto the short punch pins used in the perforating of Jaquard cards.
The heads of these pins come next to the lifting hooks of the machine, and aro
the means whereby the hooks are pressed on to or off, as the case. may be-the
grifes or lifters. The headed pins present their points outwards and come in
contact with the perforated cards or strips of metal which form the pattern.
In the case of "lags" being used, that is to say, substitutes for perforated cards
on which are formed projections in lieu of perforations, the case of headed pins is
dispensed with; and I mount the cylinder carrying the "lags" in such a position
that the lags or projections will themselves directly press upon the looped lifting
hooks aforesaid, and so actuate the same.
The improvements may be applied to either single or double lift machines, and
may be varied in the form of the details without departing from the peculiar
character of the invention.

'I, JOHN EDWARD WADSWORTH, of 530 Oldham Road, Manchester; Mechanic, do
hereby declare the nature of my invention for "IMPROVEMENTS IN INDEX
MACHINES OR DOBBIES EMPLOYED IN 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:-
The improvements relate to what are known as Index machines or Dobbies
which are a modified form of jacquard machines employed in looms for weaving,
and the said improvements consist of peculiar arrangements for actuating the
hooks of such machines, whereby the ordinary cross wires with loops and their.
springs are dispensed with.
1
To accomplish this and to effect my improvements, I form the hooks of
sufficient length to allow of a folded or looped end, which when fitted in a slide
constitutes a spring action as is well understood. In front of the row of hooks for
the purpose of actuating the same, I fix a case, or box, or it may be a block, which
is perforated at the requisite distances, in which perforations headed pins are 1
placed, very like unto the short punch pins used in the perforating of jacquard
cards.
The heads of these pins come next to the lifting hooks of the machine, and are
the means whereby the hooks are pressed on to or off, as the case may be,-the-
grifes or lifters. The headed pins present their points outwards and come in
contact with the perforated cards or strips of metal which form the pattern.
In the case of "lags "being used, that is to say, substitutes for perforated cards
on which are formed projections in lieu of perforations, the case of headed pins is
dispensed with; and I mount the cylinder carrying the "lags" in such a position
that the "lags" or projections will themselves press upon the looped lifting hooks
aforesaid, and so actuate the same.
The improvements may be applied to either single or double lift machines, and
may be varied in the form of the details, without departing from the peculiar
character of the invention.
But that the improvements may be better understood, I will by the aid of the
accompanying drawings proceed more fully to describe means employed by me.
DESCRIPTION OF DRAWINGS.

page_text: lift. b, b, are the headed pins carried by the box, case, block, or bar c, c, and
acted upon by the cards d, d, as they are brought to bear by the cylinder e, e,
which is actuated by any ordinary or other mechanism as is well understood.
ff, are the "lags" and f₁, f, the projections thereon which are in like manner
brought to bear on the hooks direct, in place of the headed pins before-named.
g, g, are the grifes or knives which may be of any convenient form and may be
operated in the usual or other convenient manner, and variations may be made in
all the actuating motions without departing from the invention.
The headed pins may be employed without the looped hooks as other or any
form of hook may be used. And the hooks may be fitted or not at their bottom
ends with the supplemental loops h, h, for carrying the heald shafts, or the same
may be attached direct.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed-I declare that what
I claim is
1. The construction of Index machines or Dobbies in such manner that the
cards operate upon headed pins mounted in any convenient way which actuate
directly hooks of wire formed with loops, or other spring action, whether in single
or double lift, substantially as shewn and described.
2. The construction of Index machines or Dobbies in such manner that the
projections on the "lags" operate directly upon and actuate hooks of wire formed
with loops or other spring action whether in single or double lift, substantially as
shewn and described.
