I HADDEN WILLIAM TODD of St Helen's Iron Works St Helens in the County
of Lancaster, Engineer, do hereby declare the nature of the said invention for
"IMPROVEMENTS IN METALLIC DRUMS FOR CONTAINING CHEMICAL AND OTHER
SUBSTANCES "to be as follows:-
The object of my invention is to provide for general use by Chemical Manufac-
turers, Dryaalters, Paint Manufacturers and others, a metallic drum or package,
possessing greater rigidity, and hence greater durability from a given thickness of
metal, than has been possible heretofore.
For this purpose I corrugate the body of the drum or. package circumferentially
in such manner that the corrugations stand out from the body of the drum or
package at suitable distances apart so as to lend additional strength thereto. I
prefer that the drum or package should be cylindrical, and that each corrugation
should consist of a flut narrow beading, and that the distance between the corruga-
tions should be greatly in excess of their width.
In combination with a drum or package having a body corrugated as above
setforth I use a double or vee shaped hoop to strengthen the body at each end.
Ends being attached in any usual or suitable way.
To further strengthen the drum or package at the chime I corrugate the double
or vee shaped hoop after it is in position over the ends and body.

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a perspective view, and fig. 2 a vertical section of a metallic drum or
package constructed in accordance with my invention. The body of the drum 1
consists of thin sheet metal made with circumferential corrugations a which stand
out from the body b of the drum, and are at a greater distance apart than their
width, care vee shaped hoops which are used to unite the ends d to the body;
at e the vee shaped hoops are corrugated to cause them to hold the end and body
more securely together. The various parts are united by rivetting in the usual 2
way and the corrugations are produced by rolls or other suitable apparatus.
The ends of the drum may be joined to the body if desired without the use of
the vee shaped hoops.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
First. Metallic drums with circumferential corrugations substantially as setforth.
Second. Metallic corrugated drums in combination with vee shaped hoops sub-
stantially as heroin setforth.
Third. Metallic, corrugated drums with corrugated end hoops substantially as
herein setforth.
