IMPROVEMENTS IN MAKING THE JOINTS OF TANKS, CISTERNS, AND IRON WORK GENERALLY
Year: 1884

page_text: We PHILIP JOSEPH WALSH of 17 Duke Street Manchester Square in the county
of Middlesex, Civil Engineer and GEORGE WADE SHARE, of 72 King William Street
in the city of London, Iron Merchant do hereby declare the nature of the said
Philip Joseph Walsh's invention for "IMPROVEMENTS IN MAKING THE JOINTS OF
TANKS, CISTERNS, AND IRON WORK GENERALLY," to be as follows:-
This invention relates to certain improvements in iron tanks and cisterns for
water and cattle troughs, and buckets, hot water tanks, circulating tanks, or
cylinders, and other iron vessels for containing hot and cold water and other liquids;
also for iron cases known as ships' tanks which are used as packing cases and water
tanks, brewing boilers, or coppers, steam boilers galvanizing and tinning pots, and
other vessels for holding molten metals when such vessels are subjected to great
heat rivetted wrought iron pipes and so forth.
Instead of rivetting in the ordinary way we introduce a strip of asbestos cloth,
or tape or cloth rendered non-combustible or other non-combustible materials
between the plates or sheets to be rivetted together and rivet the same.
In this manner the articles so rivetted are made perfectly tight and can be
galvanized or be rendered non-corrosive by other processes. It is known that light
iron tanks, cisterns and so forth in which the plates or sheets used are too thin to
make caulking efficient are dependent upon the metal from the galvanizing or
tinning pot to make them water tight whereas by our method they would be
rendered sound in the first instance. In heavy iron tanks, cisterns and so forth
constructed upon angle iron frames or where plates are rivetted to angle iron we.
insert the non-combustible material between the angle iron and plates or in the
"lap" of plates where there are lap-joints or between the cover plates over the
butting edges of plates where there are butt-joints and rivet in the ordinary way.
In all cases the rivets pass through the iron and through the non-combustible
material so holding both tightly together and forming steam and water-tight
joints.
In connection with this we use what is known as a corner rivet for tanks and
cisterns, that is a rivet with a flat head slightly counter-sunk on the neck and
against the bottom of the countersink we put a washer of the non-combustible

page_text: material before inserting the rivet and then rivet as described. We also make a
corner by means of a cap of either wrought or malleable cast iron fixed on the
outside of the tank or cistern with the non-combustible material between that and
the plates or hollow shaped stud or rivet in wrought or malleable iron to fix in the
corner on the inside with or without a shank for rivetting or "knocking" "down
outside. In either case the non-combustible material would be inserted between
the stud or rivet and the plates.
دو
Cast iron tanks and cisterns will according to this invention be provided with
the non-combustible joints and bolts at the joints of the plates or flanges and
by this means are rendered water-tight and steam-tight and can be made non-
corrosive.

page_text: We PHILLIP JOSEPH WALSH of, 17 Duke Street, Manchester Square in the county
of Middlesex Civil Engineer and GEORGE WADE SHARE of 72 King William Street
in the city of London Iron Merchant do hereby declare the nature of our invention'
for "IMPROVEMENTS IN MAKING THE JOINTS OF TANKS, CISTERNS AND IRON WORK
GENERALLY 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 certain improvements in iron tanks and cisterns for
water and cattle troughs and buckets, hot water tanks, circulating tanks or
cylinders and other iron vessels for containing hot and cold water and other liquids
also for iron cases known as ships' tanks which are used as packing cases and water
tanks, rivetted, wrought iron pipes and so forth brewing boilers or coppers, steam
boilers galvanizing and tinning pots and other vessels for holding molten metals
and so forth.
Instead of rivetting in the ordinary way we introduce a strip of asbestos cloth
or tape or cloth rendered non-combustible or other non-combustible materials
between the plates or sheets to be rivetted together and then rivet the same.

In this manner the articles so rivetted are made perfectly tight and can be
galvanized or be rendered non corrosive by other processes. It is known that light
iron tanks cisterns and so forth in which the plates or sheets used are too thin to
make caulking efficient are dependant upon the metal from the galvanizing or
tinning pot to make them water tight whereas by our method they would be
rendered sound in the first instance. In heavy iron tanks, cisterns and so forth
constructed upon angle iron frames or where plates are rivetted to angle iron, we
insert the non-combustible material between the angle iron and plates or in the
lap" of plates where there are lap-joints or between the cover plates over the
butting edges of plates where there are butt joints and rivet in the ordinary way.
In all cases the rivets pass through the iron and through the non-combustible
material so holding both tightly together and forming steam and water tight joints.
In connection with the lap jointed tanks and cisterns and so forth we use what is
known as a corner rivet that is a rivet with a flat head slightly counter-sunk on the
neck and against the bottom of the counter-sink we put a washer of the non-
combustible material before inserting the rivet and then rivet as described. We
also make a corner by means of a hollow shaped stud or rivet in wrought or
malleable iron to fix in the corner on the inside with or without a shank for
rivetting or "knocking down" outside.
In either case the non-combustible material would be inserted between the stud
or rivet and the plates.
Cast iron tanks and cisterns will according to this invention be provided with
a non-combustible material in the joints and will be bolted at the joints or flanges
and by this means are rendered water-tight and steam-tight and can be made non-
corrosive.
In the accompanying sheet of drawings Fig 1 represents an isometrical view of
an ordinary wrought iron tank or cistern constructed according to our invention of
sheet iron or wrought iron plates, flanged or bent to form the corners with the
non-combustible material in the joints at a and the corner rivets with the non-
combustible washers at 6 and where there are two or more plates in the sides,
bottoms, or top, the said non-combustible material is inserted between each and
every joint.

page_text: Fig 2 is a longitudinal section of a similar cistern or tank, showing the non-
combustible material c between the joints.
Fig 3 is a longitudinal section of a wrought iron tank or cistern constructed upon
an angle iron frame D with the non-combustible material c between the joints as
shown in which case the corner rivets are dispensed with.
Figs 4 and 5 respectively illustrate lap and butt joints, with the non-combustible
material e inserted at e and fas applicable to cisterns and tanks or to steam boilers
and other heavy or light iron work.
Fig 6 represents an ordinary corner rivet with the non-combustible washer c
as applied thereto when ready for inserting into its place in the tank or cistern.
Fig 7 shows on an enlarged scale a perspective view of the hollow headed corner
rivet herein referred to and Fig 8 is a similar view of the corner piece employed in
place of such hollow headed rivet, in which case the plates in the corners of the
tanks or cisterns are slightly cut away and these corner pieces are attached to the
tank or cistern on the inside, with the non-combustible material between the said
corner pieces and the plates of the tank or cistern to which they are rivetted in the
usual way.
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-The improvements in rivetting iron work with non-combustible
material disposed intermediately in the joints as herein set forth and described in
reference to and shown by the accompanying sheet of drawings.
