Improvements in and connected with Chain Links, such being
specially applicable to Loom Pattern Mechanism.
We, ROBERTS BEAUMONT, Professor of Textile Industries, of The Yorkshire
College, Leeds, and GEORGE WASHINGTON, Assistant Lecturer of the said
College, 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:-
"
Our invention relates to certain improvements in and connected with "links or
connections; which are specially applicable to loom pattern mechanism.
The object of our said invention being to provide a link for connecting rods or
other pieces into a chain or series, in such a manner that while each rod or piece is
perfectly free to turn round on its axis or centre lateral or sideway movement is
prevented; also to provide means whereby the said link is securely fastened in
position automatically, and easily detached by the fingers when required.
Fig. 1, is a plan showing our improvements applied to the construction of loom
pattern mechanism shown, described, and claimed by us under Patent 19,906
of 1891.
Fig. 2, is a side elevation of "link" constructed according to our improvements.
Fig. 3, is a side elevation partly in section, through the line A, B, of Fig. 1.
Fig. 4, is an enlarged side elevation of link in accordance with our improvements.
Fig. 5, is a plan of Fig. 4.
According to our invention the link C is provided with a spring or springs D and
openings E to make room for the said spring or springs to work, the said openings E
are made large enough for the spring to work up and down in, but if any lateral
pressure is put on, the spring or springs are supported by the edges F of the said
operings.
The form of link shown in Figs. 1, 2, and 3 is for a chain when the rods are in
pairs and only one of the rods requires fastening to the link (see our Specifi-
cation, 19,906 of 1891) but this form can be varied or modified to suit different
kinds of chains.
The rods G on which the links are placed have preferably pointed or rounded
ends, and are provided or made with recesses or grooves H. When the link C is
placed on the rod G the round end raises the spring D from its normal position and
the rod holds it up until it comes over the recesses or grooves H when it
immediately clips or falls into such recess or groove, so that the link and rod are
securely fastened, and the link cannot be taken off again until the spring D is
raised out of the recess or groove H by the finger or other means, when it can be
readily taken off the rod.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be perforined, we declare that what we
claim is :-
1. Links or connecting pieces having springs adapted to engage with recesses or
grooves upon rods, or the like, substantially as shown and described.
2. In loom pattern mechanism the combination of end links or connecting pieces
having springs or clips, and rods having recesses or grooves into which the said

page_text: springs or clips enter when the links are placed in position upon the rods, substan-
tially as and for the purposes shown and described.
