PROVISIONAL SPECIFICATION.
Improvements in Paint Tins, Metal Drums, and other like
Cylindrical Vessels.
I, JOHN ALBERT HOWELL, of Church Lane, East Street, Bedminster, Somersetshire,
do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved construction of cylindrical vessels generally.
In carrying out my invention I first prepare a cylinder with open ends of tin, sheet
iron, brass, copper, or any other suitable metal to form a drum or cylindrical vessel for
eventually holding and containing paints, oils or other liquids, or solids of more or less
perishable nature.
The piece or pieces of metal forming the cylinder I solder, braze, rivet or otherwise
fasten together in a manner to make and form a perfectly secure and tight joint.
At both ends of the cylinder I bend, bead or rivet the metal forming the cylinder
over an outside ring or hoop of wire or metal, to give strength and stiffness to the
ends.
I then proceed to form the bottom and cover of my cylinder, preferably each in one
piece, by first giving them a circular disc-like shape, and then flange back the edge of
the disc to form a flat dish in a suitable machine. I then bend and curl the edge of
the flange outward to give it a hook-like form of corresponding dimensions to the
stiffening wire or metal ring or hoop, already fixed at both ends of the cylinder.
The bottom and the cover being thus suitably prepared and made to fit tightly the
inside of the cylinder, I first press the bottom home and in its place and then bead or
rivet the outer hook-like edge of it over the wire, or metal ring or hoop, and thus
secure a perfectly tight and compact closing of one end of my cylinder.
To give additional security or tightness I may, and I prefer to, solder or braze the
beaded or rivetted part of the bottom to the cylinder.
When the vessel is filled with any desired substance or liquid I then press home also
the cover and treat it in a similar manner, as already described in my method of fixing
the bottom, and thus finish and complete iny cylindrical drum or vessel.

In carrying out my invention I first prepare a cylinder A. with open ends, of tin,
sheet iron brass, copper or any other suitable material or metal to form a drum or
cylindrical vessel.
The piece or pieces of metal or material forming the cylinder I solder, braze, rivet
or otherwise fasten together in such a manner as to make a perfectly secure and tight
joint.
At both ends of the cylinder 1 bend bead or rivet the metal or material forming the
same over an outside ring or hoop of wire metal or other suitable material B (see
Fig. 3) to give strength and stiffness to the ends of the cylinder.
I then proceed to form the bottom and cover C. E of my cylinder A preferably each
in one piece by first giving them a circular or disc like shape and then flanging back
the edge of the disc as at D to form a flat dish which operation may be performed in
any suitable machine.
I then bend and curl the edge of the flange D outward as shewn in Fig. 3. to give it.
a hook-like form of corresponding dimensions to the stiffening wire or metal or other
suitable material ring or hoop B already fixed at both ends of the cylinder.
The bottom C and the cover E being thus suitably prepared and made to fit tightly
the inside of the cylinder I press the bottom C home and to its place and then bead or
rivet the outer hook-like edge of it over the wire or metal or other suitable material
ring or hoop and thus secure a perfectly tight and compact closing of one end of
my cylinder.
To give additional security or tightness I may and I prefer to, solder or braze the
beaded or rivetted part of the bottom to the cylinder.
When the vessel is filled with any desired substance or liquid I press home also the
cover and treat it in a similar manner to that already described in my method of fixing

page_text: the bottom and I thus finish my cylindrical drum or vessel. Although I have referred
in this specification to a cylinder it is obvious that the shape or section of the vessel
and its top and bottom covers may be varied without departing from the spirit of the
invention.
The method of attaching handles (if such are required) by hooking bent wires or
strips with ears, rivetted soldered or otherwise secured to the body of the vessel is not
claimed as part of my invention although shewn on the drawings.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is.
First. The manufacture of tins, drums or like receptacles substantially as described
and illustrated in the accompanying drawings.
Secondly. The method hereinbefore described of uniting the end covers to the body
of a tin, drum or like vessel consisting in bending its ends over wires hoops or frames
of metal or other suitable material and then beading, rivetting or securing the hook
shaped edges of such described flanged or dished covers over the solid bead or flange
so formed on the ends of the body substantially as set forth.
