IMPROVEMENTS IN LINKS
Year: 1885

page_text: We, THOMAS WHITE of Thorpe Hesley, near Rotherham, in the County of York,
Engineer, and GEORGE HENRY DIXON, of Brightside, Sheffield, in the County
of York, Manager, do hereby declare the nature of our said invention for
"IMPROVEMENTS IN LINKS," to be as follows:-
This invention relates to links of any kind, and is practically a coupling or
connecting link.
This invention consists of a link of any shape, length, or thickness, and may be.
made of any convenient metal.
The said link is made in two or more pieces, one or more pieces being dovetailed
in the side of the link, the loose piece or pieces being made to slide through on one
or both sides of the link, the said piece or pieces being held securely in position by
two metal plates, one of which is placed on each side of the said link, meeting in
the centre and held in position by a screw, nut, bolt, or any other convenient
appliance, the said plates being bevelled to fit the side of the link.
When the said plates are placed in position and screwed up, they hold the loose
pieces firmly to the other part of the link, preventing them from falling or being
pulled out, at the same time allowing sufficient space on either side, required to
couple a link of the same size.
This link consists of two or more pieces dovetailed, having the two sides or ends
of the link loose, and the said pieces held in position as above described.

page_text: We, THOMAS WHITE, of Thorpe Hesley, near Rotherham, in the county of York,
Engineer, and GEORGE HENRY DIXON, of Brightside, Sheffield, in the county of
York, manager, do hereby declare the nature of. our said invention for "IMPROVE
MENTS IN LINKS FOR CHAINS AND THE LIKE," 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 links of any shape, length, or thickness and having a
loose piece dovetailed in the side of the link forms a coupling or connecting link
for chains and the like.
The said link may be made in two or more pieces but we intend to make it in
two pieces only one piece being made to slide into a dovetail in the side of the link
which is formed to receive it. This piece when inserted in the dovetail is held
securely in position by one or more metal plates placed in the centre of the link
and held firmly by means of a screw, nut, bolt, or their equivalents, the said plates
being bevelled to fit the inside of the link.
If one plate only be employed the screw or its equivalent will be placed through
the loose piece, the centre plate and into the bottom of the link which is tapped to
receive it, but if we use two plates one placed at each side of the link the screw
or its equivalent will be placed through the centre of the plates.
When the said plate or plates are put into position and screwed up they hold
the loose piece firmly to the other part of the link preventing it from falling
or being pulled out, at the same time allowing sufficient space on either side
required to couple a link of the same size.
The links as above described may be forged or cast, by preference cast, from any
suitable metal,
The accompanying drawings illustrate our invention.
Fig. 1. is a plan or front view of link shewing loose piece A in position with
one centre plate B held firmly by screw C passing through the said loose piece and
centre plate into bottom part of the link.
Fig. 2. is a plan shewing loose piece D apart from link ready for coupling.
Fig. 3. is a section through Y. Z. of centre plate B.
Fig. 4. is a section of two centre plates for Fig. 2. shewing mode of fastening.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
Firstly. Improvements in chain coupling or connecting links having a loose
piece which is dovetailed in the side of the link and held in position by one or
more centre plates securely fastened by screws or their equivalents.
Secondly, Improvements in coupling or connecting links as herein-before
specified, described and illustrated by the accompanying drawings.
