I ROBERT JACKSON of St. Marys Villa Rainhill in the county of Lancaster
Timber Merchant, do hereby declare the nature of this invention to be as follows:-
The object is to provide for containing caustic soda and like substances, a drum and
lid so made that the lid is easily and securely applied, and readily removed when
required.
The invention consists essentially, in constructing one end of the drum with an
aperture baving inward turned edges, and a lid with one or more projecting clips
and guide pieces.
A further improvement consists, in providing the lid with an aperture or means
whereby the clips may be detached and the lid removed.

the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The object is to provide for containing caustic soda and like substances a drum
and lid so made that the lid is easily and securely applied and readily removed when
required.
The invention consists essentially in constructing one end of the drum with an

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a section fig. 2 a view looking up and fig. 3 a plan of as much of a
metallic drum and lid as is required to illustrate my invention. a drum head secured
to the body of the drum in any usual or convenient way and having a circular
aperture therethrough. inwardly turned edges of the drum head forming the
boundary of the circular aperture. d lid formed with two projecting guide pieces e
and two projecting clips f. The number and position and size of the guide pieces
and clips may be varied as desired or clips only may be used. The turned down
edges of the head extend entirely or only in part round the circular aperture are of
the same or varying depths all round and have sufficient elasticity to allow of the
lid being easily forced into the position shown in fig. 1 with the clips locked by the
said turned down edges. The aperture may be square hexagonal elliptical or of other
shape but I prefer that it should be circular and that the edges of the head should
be turned down an equal distance all round. In this way the lid will fit in any
position. aperture or recess in the lid. The end of a wrench or chisel is
inserted in the said aperture when it is desired to remove the lid and the said lid is
prised off.
Having now particularly described and ascertained the nature of the said inven-"
tion and in what manner the same is to be performed I declare that what I
claim is,
First. Constructing metallic drums and lids with apertures and clips substantially
as set forth.
Second. Drum lids with clips and an aperture or recess for the purpose set
forth.
