PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Connecting and
Adjusting Healds in Looms for Weaving.
I. GEORGE DYSON SYKES, of Upperhead Row, Huddersfield, in the County of
York, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
:-
This invention has reference to means to be employed for connecting and
adjusting healds of looms to the levers arranged above and below them, and which
are employed for opening and closing the "shed." As is well known, the top and
bottom shafts are connected by cords, straps, or chains to the operating levers, and
it is difficult to connect the levers to the healds to exactly the same height or level
position, as in the tying of knots, or the punching of holes, a slight difference in
the length of the connection often occurs, which causes an uneven shed. The object
of my invention is to provide a form of connection which will be readily adjustable
in either direction so that a perfectly even shed can be readily formed.
In carrying out my invention, I employ, between the top and bottom shafts of
the healds and the operating levers one or two right and left handed screws (or
single screws may be employed) with or without swivelling heads, working in nuts,
which nuts on being turned by the operative, will either lengthen or shorten the
cords, straps, or chains supporting the healds to any exact position, so that when
connecting the healds to the levers by cords, straps, or chains, as formerly, the care
hitherto exercised in connecting them to exactly the same length will not be
necessary, as after they have been connected, they can be adjusted by the nuts and
screws mentioned above.
By the employment of my improved adjustable connection, considerable time is
saved in connecting the healds to their levers.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Connecting and
Adjusting Healds in Looms for Weaving.
I, GEORGE DYSON SYKES, of Upperhead Row, Huddersfield, in the County of
York, Manufacturer, 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 :-
This invention has reference to means to be employed for connecting and
adjusting healds of looms to the levers arranged above and below them, and which
are employed for opening and closing the "shed." As is well known, the top and
bottom shafts of the healds are connected by cords, straps, or chains, to the
operating levers, and it is difficult to connect the levers to the healds to exactly
the same height or level position, as in the tying of knots or the punching of holes,
a slight difference in the length of the connection often occurs, which causes an
uneven shed. The object of my invention is to construct a form of connection
which will be readily adjustable in either direction, so that a perfectly even shed
can be readily formed.

page_text: Such being the nature and purpose of my invention, I will now explain and
illustrate the same by referring to the attached drawings, in which
Fig. 1 is elevation of my improved adjustable connecting device
appliance, and
Fig. 2 is a vertical section of same.
or
A represents the top heald shaft with its ordinary hook B. The jack levers (not
shewn in the drawings) are connected by chain or cord or strap C to a loop D
forming part of my improved device, which consists primarily of a tube E
containing at each end a nut F having an internal screw thread formed in it. This
nut is shewn detached at Fig. 6, and it is made with one or more grooves a, so as to
be secured in the end of the tule E by indenting or pressing a portion of the tube
within the grooves a, or the said screwed nut F may be attached to the tube by
pins, rivets, or other suitable means. Within each nut is a screw G provided at
one end with a loop D and at the other end with a head H to prevent the screw
being withdrawn from the nut, as would happen without the said head. I, I, are
locknuts for fastening the screw when it has been adjusted to the required length.
The screw threads on the screws G are right and left hand, so that on the lock-
nuts I being loosened, the operative, by turning the tube around with his hand,
draws the parts nearer together or further away as desired, so that when connecting
the healds to the jack levers either under or above the loom, they can be quickly
and readily adjusted to the greatest nicety, whereby an even shed can always be
formed.
Fig. 5 is a cross-section through line c in Fig. 2.
Instead of employing the tubes F, filled up at each end with a screwed nut as
shewn at Figs. 1 and 2, a different form of tube may be used as shewn in Figs. 3
and 4, both ends of which tube are provided with screw threads. Locknuts I are
also employed for fastening the screws when once adjusted.
Although I have shewn and described an adjustable screw at each end of the
heald adjusting device or appliance, I would observe that one end of the tube may
be provided with a swivel ring or hook without screw thread, as a screw-thread at
the opposite end of the instrument would be sufficient for adjusting the parts.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
An adjusting device or appliance constructed and operated in the manner
substantially as herein shewn and described, for adjusting the heald shafts in looms
for weaving.
