PROVISIONAL SPECIFICATION.
Improvements in and relating to Tanks, Cisterns, Casks, Drums,
and the like.
We, EDWIN YATES and JOHN MCQUEEN, both of Smith and Maclean Limited,
Manufacturers, Mavisbank, in the County of the City of Glasgow, do hereby
declare the nature of our invention to be as follows:-
.
This invention has reference to improvements in and relating to sheet metal
tanks, cisterns, casks, drums, and the like.
According to our improvements we secure the top cover and the bottom to
the body part, which may be of cylindrical, square, or other shape without the
use of rivets or other fastenings by forming the connections of both body part
and end covers with corrugated or fluted indentations so that the parts are
securely pressed together. The indentations may be done either concave or
convex. This would or may be effected by taking a die tool within the tank
or vessel and securing the top cover first by the corresponding piston die tool of
an hydraulic machine on the outside, and then placing the bottom end in posi-
tion and using corresponding die tools to indent and secure same to the body
part.

Improvements in and relating to Tanks, Cisterns, Casks, Drums,
and the like.
We, EDWIN YATES and JOHN MCQUEEN, both of Smith and Maclean Limited,
Manufacturers, Mavisbank, in the County of the City of Glasgow, do hereby
declare the nature of our invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say:-
This invention has reference to improvements in and relating to sheet metal
tanks, cisterns, casks, drums, and the like.
And in order that our said invention may be properly understood we have
hereunto appended a drawing representing a sectional elevation of a water circu-
lating tank having its end covers secured in accordance with our improvements.
Referring to said drawing:
-
According to our improvements we secure the top cover a and the bottom b

page_text: to the body part c which may be of cylindrical, square, or other shape, without
the use of rivets or other fastenings, by forming the connections of both body
part and end covers a b with corrugated or fluted indentations cand a¹ b
so that the parts are securely pressed together. The indentations may be done
either concave as shown or convex, and instead of having only one indent, two
or more of such corrugations may be effected at the top and bottom covers. This
would or may be effected by taking a die tool within the tank or vessel and
securing the top cover a first by the corresponding piston die tool of an ordinary
hydraulic machine on the outside, and then placing the bottom end b in position
and using corresponding die tools to indent and secure same to the body part c.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
First. In sheet metal tanks, cisterns, casks, drums, and the like, the form-
ing of the connections of both body part and end covers with corrugated or fluted
indentations, and pressing these together by die or equivalent tools, substantially
as set forth.
Second. Sheet metal tanks, cisterns, casks, drums, and the like, having their
end covers and body part indented and secured together without the use of rivets
or other fastenings, substantially as set forth.
