PROVISIONAL SPECIFICATION.
Improvements relating to Loom Drop Box Motions.
I, JOHN WILLIAM FIELDING of Bentinck Street Mill, Moses Gate near Bolton
in the County of Lancaster, Overlooker, do hereby declare the nature of my said
invention to be as follows:-
This invention relates to that class of looms known as "check-looms," or looms for
weaving patterns of varying colors and designs in which drop boxes and pattern
cards or plates are employed and consists in means to supersede the elastic or india-
rubber bands employed to prevent the pattern cards or plates becoming detached
from their carrying chains. In or over the slots or openings on the ends of each
pattern card or plate to admit their connecting or carrying chains I place a steel or
other metallic clip composed of two spring plates secured together sufficiently
apart by an eyelet or other equivalents; being of such a length as to extend on the
pattern card or plate to secure the same in position and prevent the chains locking
each other.

COMPLETE SPECIFICATION.
Improvements relating to Loom Drop Box Motions.
I, JOHN WILLIAM FIELDING of Bentinck Street Mill, Moses Gate near Bolton
in the County of Lancaster, Overlooker, do hereby declare the nature of my said
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 relates to that class of looms known as "check-looms," or looms
for weaving patterns of varying colors and designs in which drop boxes and pattern
cards or plates are employed and consists in means to supersede the elastic or india-
rubber bands employed to prevent the pattern cards or plates becoming detached
from their carrying chains. In or over the slots or openings on the ends of each
pattern card or plate to admit their connecting or carrying chains I place a steel or
other metallic clip composed of two spring plates secured together sufficiently apart
by an eyelet or other equivalents; being of such a length as to extend on the
pattern card or plate to secure the same in position and prevent the chains locking
each other.
Fig. 1 is a longitudinal elevation of pattern cards or plates with my improved
clips for preventing the same becoming detached from their carrying chaius-
Fig. 2 is an end elevation of a pattern card or plate with my improved clip in
position-
Fig. 3 is a sectional view of my improved clip-
Fig. 4 is a longitudinal elevation of a pattern card or plate with my improved
clips for locking the carrying chains in position, and
Fig. 5 is a sectional plan through line S T in Fig. 4.
A, A, are pattern cards or plates employed in what are known as
"check looms,"
or looms for weaving patterns of varying colors and designs, and B are chains for
coupling the pattern cards or plates. The chains B are placed in the recesses C as
shown, after which they are secured therein by means of the steel or other metallic
clips D, slipped on or over the ends of the pattern cards or plates A. The clip D
is composed of two plates rivetted to the eyelet or distance piece E of sufficient
[Price bd l

page_text: width according to the thickness of the pattern card or plate. If desired the
clip D can be constructed of one piece of steel or other flexible metal as shown in
Figs. 4 and 5, in which case the distance piece E is dispensed with. When it is
necessary to remove this latter kind of clip it is effected by springing the same
open until it will slide off the pattern card or plate. The clips D are made
sufficiently long so as to extend on the pattern cards or plates to secure them firmly
in position and to prevent the chains B locking each other in the various movements
and positions through which they have to travel.
This invention is designed to supersede the clastic or india-rubber bands at
present employed to prevent the pattern cards or plates becoming detached from
the carrying chains B. Owing to the use of elastic or india-rubber rings for the
purpose specified it is necessary to provide the pattern cards or plates with the
slots G to receive the same, which are entirely dispensed with and unnecessary when
employing my improved clips.
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 :-
In combination with pattern cards or plates the use and construction of the
clips D for the purpose specified, substantially as described.
