Improvements in and relating to Fluid-pressure Joints on Doors,
Pipes, and the like.
We, DAVID ALEXANDER BLAIR and JAMES BARTON BLAIR, both of Scotland
Street, in the City and County of Glasgow, Manufacturing Coppersmiths, and
ROBERT BAILLIE, Draughtsman, of 3, Kirkwood Street, Ibrox Govan, in the County
of Lanark, do hereby declare the nature of our invention to be as follows:-
This invention relates to the jointing of two metal flanges or faces round doors,
pipes and the like, and has reference more particularly to the arrangement of tee
or other headed bolts and nuts such that the joints can be readily connected and
disconnected by a few turns of the nuts and the non removal of the bolts, the
bolts being strung together and swivelled or pivotted on a wire or rod when
placing in or out of position, this rod or wire being continued and jointed to suit.
The flanges or faces of doors or pipes to be jointed together are provided with
the number of bolts pitched to suit but the holes are open at the side outwards,
instead of being closed as in the ordinary hole. This enables the bolts and nuts
to be inserted sideways, but the head of each of the bolts has a hole mads or drilled
through it and a wire or rod is passed through each, the whole being strung
together, each in their proper place and each free to be screwed up to draw the
faces of joint together and also each swivelled or pivotted loosely and indepen-,
dently of the other. This enables the jointing and disjointing to be done without
removing the bolts or nuts and so throws the whole stress, of drawing joints
together, on the head of the bolt and nut directly and not on the wire, rod, or
string which only keep the bolts together.
The wire or rod being continuous requires to be coupled or jointed such as by a
sliding link or by screw threaded ends and nut, and it may also require to be
supported by light catches.

page_text: by the following statement in writing, reference being made to the accom-
panying drawings:-
-
This invention relates to the jointing of two metal flanges or faces round doors,
pipes and the like, and has reference more particularly to the arrangement of T
or other headed bolts and nuts such that the joints can be readily connected and
disconnected by a few turns of the nuts and the non-removal of the bolts, the
bolts being strung together and swivelled or pivotted on a wire or rod when
placing in or out of position, this rod or wire being continuous and jointed to
suit.
And in order that our said invention and the manner of carrying same into
practice may be properly understood, we have hereunto appended a sheet of
explanatory drawings in which the same reference letters are used to indicate
corresponding parts in all the figures where shown. Figure 1 is a back view,
Figure 2 a section of joint, and Figure 3 a front view of a door as fitted with our
improvements.
Figures 4, 5 and 6 are detached enlarged views showing the back, section and
front of flange respectively. And Figures 7 and 8 are views of pipe joints and
the like as formed in accordance with my improvements.
Referring to these drawings:-
--
The flanges or faces A of doors or pipes to be jointed together are provided with
the number of bolts 6 pitched to suit but the holes a are open at the side outwards,
instead of being closed as in the ordinary hole. This enables the bolts b and
nuts to be inserted sideways, but the head 63 of each of the bolts has a hole
made or drilled through it and a wire or rod c is passed through each, the whole
being strung together, each in their proper place and each free to be screwed up
to draw the faces of joint together and also each swivelled or pivotted loosely and
independently of the other. This enables the jointing and disjointing to be done
without removing the bolts or nuts and so throws the whole stress, of drawing
joints together, on the head of the bolt and nut directly and not on the wire,
rod, or string c which only keeps the bolts together.
The wire or rod c being continuous requires to be coupled or jointed such as
by a sliding link c¹ or by screw threaded ends and nuts, and it may also require
to be supported by light catches, such as a¹ where the joint is horizontal.
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:-
First. Fluid pressure joints on doors, pipes and the like formed and fitted
substantially as herein described in reference to and shown in the accompanying
drawings.
Second. In connection with fluid-pressure joints on doors, pipes and the like,
the combination comprising open sided holes in the flanges, securing bolts and a
continuous wire rod, or the like on to which the bolts are strung, substantially
as herein described in reference to and shown in the accompanying drawings.
