Improved Means for Joining the Sheets or Plates in the Manufacture
of Metal Tanks, Boxes, and the like.
We, WILLIAM ORR, Merchant, and PETER STUART BROWN, Manufacturer, both of
109, Saint Vincent Street, Glasgow, in the County of Lanark, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improved means for joining together metal sheets or plates
in the manufacture of close or open tanks boxes and like articles and in preparing to
construct a tank or box in accordance with the invention a triangular piece is severed
or removed from each corner of the sheet or plate. The edges of the sheet or plate
are then bent back or returned and over the returned edges of two adjacent sheets
or plates a tube having a slot throughout its length is passed the edges of the slot
gripping the metal of the sheets. Before or after the tube has been so placed a
wedge piece preferably of double bulb cross section is inserted or forced in between
the meeting edges of the sheets the neck of the bulb being at the part where the
edges of the slotted tubes grip the sheets. This wedge piece may be composed of
lead or other fusible metal so that by the application of a heated bolt or the like to
the outer part it may be fused throughout its length to render the box or tank
watertight or it may be composed of iron or other substance and have solder red lead
or other jointing material applied for the like purpose. At the corners of the tank or
box where three tubes meet each other the tube ends are or may be inserted or
fastened into a cast iron or other washer disc or plate and on the outside of the tank
or box another plate shaped to fit the corner is placed the inside plate and the
outside plate being drawn together by a bolt passed through them the nut on which is
screwed up from either side.
For metal boxes or cases where it is desired that the cover should be easily
removable for filling and emptying purposes the cover is composed of a dished plate
having preferably an upstanding rim or flange all round the flange being formed in
such position that in dishing it up the edge of the plate is caused to project down-
wards below the body the said projecting edge fitting over the sides of the box. For
greater strength the body of the cover is also preferably corrugated, dished or
buckled. The tubes joining the sides of the box have each rivetted or otherwise
secured to their outer surface a bolt or the bolt may be situated in the hollow of the
tube but in any case it passes out through a hole in the cover which is held in
position by nuts screwed on the ends of the bolts. Where additional strength is
required in the case of square boxes an angle iron or like piece of greater thickness
may be placed over the corners of the cover or in the case of round boxes an angle
iron or other shaped ring may be used. If desired a band may also be soldered on or
otherwise fastened around the edges of the cover and sides of the box to render the
same watertight.
Metal cases so constructed can, when emptied of their contents, be with facility
taken to pieces, packed together and transported to be put together and refilled a
saving of space occupied in transporting boxes in bulk being thereby effected.

Improved Means for Joining the Sheets or Plates in the Manufacture
of Metal Tanks, Boxes, and the like.
We, WILLIAM ORR, Merchant, and PETER STUART BROWN, Manufacturer, both of
109, Saint Vincent Street, Glasgow, in the County of Lanark, 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:-
This invention relates to improved means for joining together metal sheets or plates
in the manufacture of close or open tanks boxes and like articles.
at c
As seen at Figure 1 of the accompanying drawings which is a perspective view of a
tank constructed in accordance with the invention a triangular piece a,is previously to
putting the sheets together, severed, or removed from each corner of the sheets or
plates 6. The edges of the sheet or plate are then bent back or returned as illustrated
Figure 2 which is a cross section of a joint and over the returned edges of two
adjacent sheets or plates a tube d having a slot throughout its length is passed the
edges of the slot gripping the metal of the sheets. Before or after the tube has been
so placed a wedge piece e preferably of double bulb cross section is inserted or forced
in between the meeting edges of the sheets the neck of the bulb being at the part
where the edges of the slotted tubes d grip the sheets. This wedge piece may be
composed of lead or other fusible metal so that by the application of a heated bolt or
the like to the outer part it may be fused throughout its length to render the box or
tank watertight or it may be composed of iron or other substance and have solder
red lead or other jointing material applied for the like purpose, or instead of the
wedge piece e an iron bar or rod may be driven into the tube d as seen from the
inside of the tank or box at Figure 3 and from the outside at Figure 4 the said bars
forcing the bent over parts of the sheets against the edges of the slots in the tubes.
At the corners of the tank or box where three tubes d meet each other the tube ends
are as seen at Figure 3 inserted under the curled or bent edges of a cast iron or other
disc or plate f and on the outside of the tank or box another plate 9 shaped to fit the
corner is placed the inside plate f and the outside plate being drawn together by a
bolt passed through them the nut on which is screwed up from either side.
For metal boxes or cases where it is desired that the cover should be easily remov-
able for filling and emptying purposes the box is constructed as shewn by Figures 5,
6 and 7 that is to say the cover Figure 6 is composed of a dished plate having a
downwardly projecting rim or flange all round excepting at the corners the said
projecting rim fitting over the sides of the box whilst the body of the cover rests
on turned over flanges made on the plates constituting the body and which flanges
are also cut away at the corners of the box. For greater strength the sheets of the
body and also the cover are preferably corrugated dished or buckled." The tubes d
joining the body of the box have each triangular portions cut away at their ends
as at Figure 8 and they have each also an inclined slot d made through them
into which a nut is inserted and soldered or otherwise fastened as at k Figure 7 the
bolts passing through the caps or plates g to hold the cover and bottom of the box
in position being screwed into the said nuts. To permit the end of the bolt to pass
out a circular or other shaped hole m is made in each tube under the slot d².
Where additional strength is required in the case of square boxes an angle iron
or like piece of greater thickness may be placed under and parallel with the flanges ja
at the top and bottom of the sheets 6 the said angle irons being rivetted in position
and having holes in their horizontal flanges to enable the top and bottom of the box
to be bolted or rivetted in position. In the case of round boxes an angle iron or
other shaped ring may be used.
Metal cases so constructed can, when emptied of their contents, be with facility
taken to pieces, packed up and transported to be put together and refilled a saving of
space occupied in transporting boxes in bulk being thereby effected.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare, that what we
claim is:-
--
1. In the manufacture of metallic tanks boxes and the like joining together the
several sheets or plates constituting the vessel substantially as described with
reference to the drawings annexed.
2. A joint for the sections comprising a metallic tank box or the like formed by
cutting away the meeting corners of the sheets or plates bending back the edges of
the sheets slipping a tube having a slot throughout its length over the said bent edges
driving a wedge into the said slot inserting the ends of the tubes under a disc or
plate and closing up the corners by a cap held in position by a bolt substantially as
described with reference to Figures 1, 2 and 3 of the appended drawings.
3. A joint for the section composing a metallic tank box or the like composed by
cutting away the meeting corners of the sheets or plates, bending back the edges of
the sheets, passing a tube having a slot throughout its length over the said bent
edges driving a rod or bar through the interior of the tube and so as to grip or hold
the said bent edges inserting the ends of the tubes under a disc or plate and closing
the corner by a cap held in position by a bolt substantially as described with
reference to Figures 3 and 4 of the accompanying drawings.
4. In a metallic tank box or the like the mode of connecting the lid or cover of the
vessel substantially as described with reference to Figures 5 to 8 of the drawings
annexed.
