Improvements in Flange and other Tight Joints.
I, WALTER JAMES QUICK, of 41, Sutton Street, Spring Bank, Hull, in the County
of Yorkshire, First Class B. T. Certificated Marine Engineer, 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:-
My invention relates to an improved flanged or other flat-faced joint, for the
closure of all kinds of openings or apertures, subjected to internal or external
steam, gas, or other pressure, the object of which is to provide a joint that will not
leak or blow under such pressure.
In the accompanying drawing I have chosen to illustrate the principle of my
invention as applied to the closure of a joint forming the cover of the end of a tube
or conduit for steam or gas under pressure, Fig. 1 being a vertical section of such
a jointed cover according to my invention, while Fig. 2 is a top or plan view of the
lower half of Fig. 1, such views also serving to illustrate the application of such
principle in perfecting the steam, air, or gas-tight junction of any two similar
plane surfaces, capable of being bolted or otherwise firmly connected to each other.
My invention consists in forming in the upper face or flange of the end of a tube
or other conduit, or opening such as A, having a flange or other plane surface
such as B, and arranged to be covered by or connected to the flange of a like tube
or conduit, or other plane surface, or be closed by a cap, canopy or lid such as C,
a series of annular channels or grooves such as E, which may conveniently but
not imperatively be of V shape in cross section, but of whatever shape these may be
I form corresponding annular channels or grooves F, in the under face of the
opposing flange or cover such as C, the said grooves or channels being so arranged that
the ridges or risers between and forming the grooves or channels in the one, say B,
5 may fit into and occupy the grooves or channels in the other C, thus forming a
zig-zag or interlocking-joint between them, which, when necessary, may have inter-
posed any suitable form of cement or white lead as packing, the upper portion,
flange or cover such as C, being connected to the under part or flange of the lower
portion B, by screw or through-bolts such as G, passing through holes H in C and B
in the usual way.
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 the fixation of the parts of a flanged, capped, or other flat-faced tight-joint,
35 the use and application of the herein described method of forming V or other
las moues or channels in each of the said faces, so that a zig-zag and

page_text: interlocking joint is formed between them, with or without being suitably packed,
and connected by bolts or the like substantially as set forth and shewn by the
drawing.
