Improvements in Loom Pattern Card Chains.
I, FRANCIS PHILIP MIDDLETON of Adlington, near Chorley in the County
of Lancaster, Manufacturer do hereby declare the nature of this invention to be
as follows:-
It is applicable to all looms in which a series of metallic cards (technically
termed a "chain") is employed and consists of an improved method of linking the
cards to each other.
Heretofore the most usual method of linking the cards together, has been by
means of a couple of split rings, retained in their places by means of a small india-
rubber band which is constantly becoming destroyed or broken and has to be
replaced at much loss of time and damage to material.
I substitute in place of the ordinary rings, a couple of stronger plain rings
which are formed with a suitable indentation or indentations in such a manner that
they can be passed down suitable slots in the end of the card and then turned, so as
to retain them in position, thus enabling me to dispense with the indiarubber
bands beforementioned.
Dated this 26th day of September 1890.

COMPLETE SPECIFICATION.
Improvements in Loom Pattern Card Chains.
I, FRANCIS PHILIP MIDDLETON, of Adlington near Chorley, in the County
of Lancaster, 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 :-
It is applicable to all looms in which a series of metallic cards (technically
termed a "chain") is employed, and consists of an improved method of linking the
cards to each other.
I substitute in place of the ordinary rings or couplings, a couple of strong plain
rings which are formed with a suitable indentation (or indentations) in such a
manner that they can be passed down suitable slots in the end of the card and then
turned so as to retain themselves in position without further mechanism or fitting
and removed with equal facility.
In order that the foregoing may be better understood I send herewith a sheet of
drawings in which
Fig. 1 shows a couple of metallic cards joined by my improved method
Fig. 2 a separate card and
Figs. 3 and 4 two views of a connecting ring.
In these figs. a indicates the slot in the ends of the cards into which the ring is
passed the indentation 6 in the side of the ring allowing it to pass freely until it
reaches the enlargement c in the slot a which permits of the ring being turned and
its thicker part d brought into the enlargement c securing it against accidental
withdrawal. To further secure it in its position I preferably form the ring of an
oval form with the indentation b in the flattened sides but I do not confine myself
to the particular forms shown as they are susceptible of considerable modification
in different chains.

page_text: 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 :-
The combination of one or more slots, with enlarged interior ends in a metallic
card with one or more rings with suitable indentations substantially as described
and shown herebefore and in the accompanying drawing for the purpose set
forth.
