We JOHN HARPER and EDWARD HARPER both of the Waddams Pool Works
Dudley in the County of Worcester, Iron Founders do hereby declare the nature
of our said invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :—
The object of this invention is to provide metallic or other drums or casks or
other vessels suitable for containing caustic soda or other substances with lids or
closers of various designs for closing and completely covering and if desired
rendering air tight the whole of the filling or other apertures in such drums, casks,
or other vessels in an improved and more efficient manner than that now in use.
The invention possesses the following advantages:-
1st The lids or closers tightly close and completely cover all the filling or other
apertures which are necessary for the purpose of filling or closing the drum, cask
or vessel.
2nd The drum cask or vessel may be made absolutely air-tight an advantage not
possessed by the lids or closers now in use.
3rd The lids or closers are made without the objectionable lateral flanges or
projections now in use but instead thereof they possess an internal lateral inverted
ear not projecting beyond the outer edge of the lid or closer.
4th The lids or closers will not with ordinary usage become loose or damaged in
transit.
5. They are easily removeable.
For the purpose of the said invention a metallic drum cask or other vessel is
made in the usual way with the ends properly affixed and secured. A hole or
filling aperture of circular or other outline is cut in one end of the drum-Near
the edge of such aperture two other small holes are also cut in the end of the drum
which said aperture and holes are cut for the purpose of adapting the end of the
drum for the reception in proper position for the lid or closer next described.
The lid or closer (the design construction and improvement whereof constitute
the chief novelty of our invention) is formed in one piece being on the obverse side
thereof perfectly free from any lateral or visible projections whatsoever and either
quite plain or containing a sunk or raised space or recess available for inscriptions

page_text: figures, designs, names addresses or descriptions of the contents of the drum or
vessel. On the reverse side of the lid or closer, when cast or fashioned is affixed at
a little distance from the edge a rim say about a quarter of a inch high of circular
or other shape to which is attached at right angles with the rim a small inverted
ear so shaped and affixed to the rim as to leave a space between the ear and the
lid or closer. To the said reverse side of the lid or closer when cast or fashioned
are also affixed at a short distance from the rim and at a little distance from each
other and about parrallel with the rim a hooked clip or jaw and also an oblong stop
or locking piece which respectively fit into the two small holes cut into the drum
head for the purpose of receiving the same.
.
To secure the said lid or closer in its position we place the ear (No 1) on the
under side of the metal encircling aperture A in the drum-head pass the booked
clip or jaw (No 2) through the opening b turn the lid or closer to the right until
the metal stop or locking piece (No 3) falls into the opening c. The fixing will
then be complete and will cover the whole of the apertures, A, b and c.
To open a drum cask or other vessel so closed No 3 stop or locking piece is
raised by pressing on the drum-head at c then turn the lid or closer about the
length of the undercut n of the jaw No 2 (for which purpose a key may be
provided if desired) when the lid or closer may be easily removed.
To render the lid or closer air-tight we make a groove or hollow in the drum-
head along and near the edge of the filling aperture to receive white-lead cement or
other substance which will adhere to the lid or closer and seal, cement, or fasten
same to the drum-head. The lids or closers now in use having projecting lateral
flanges over which some portion of the drum-head necessarily passes do not cover
the whole of the filling aperture therefore cannot be made with a continuous groove
or hollow for the reception of adhesive sealing matter. To render the lid or closer
(when so made air-tight) still more secure against compression or possibility of
being forced from the drum-head (after application of adhesive or sealing matter)
by reason of the imposition thereon of weighty substances or otherwise, we make
the lid or closer with one inverted ear (No 1) only and without the hooked-clip or
jaw (No 2) and stop or locking piece (No 3) and in lieu of the hooked-clip or
jaw (No 2) and stop or locking piece (No 3) we rivet or fix to the drum-head a
stud-bolt either plain or screwed (No 4) secured by a nut which may be further
fastened by a pin driven through a groove m across the nut, the nut being screwed
or fixed on to the stud bolt the reverse way up.
To secure this lid or closer in position fill the groove e with white-lead cement
or other adhesive or sealing substance place the inverted internal ear (No 1,) on
the under side of the metal encircling aperture A in the drum-head pass the other
end of the lid or closer over the stud bolt (No 4 screw down or affix the nut (No 5)
and if desired drive in the pin (No 6).
To open a drum cask or similar vessel so closed unscrew or unfix the nut (No 5)
lift the lid or closer over the stud bolt (No 4) and remove the lid.
DESCRIPTION OF DRAWINGS.
Figure 1 is a plan of the reverse side of a lid or closer made of one piece of
metal with the small inverted ear (No 1) the hooked-clip or jaw (No 2) and the
stop or locking piece (No 3) all being underneath and on the reverse side of the
said lid or closer and invisible from the obverse side thereof.
Figures. 2. respectively. Represent two side views of a drum-head at right angles
to each other with our improved lid or closer fixed in position.
Figure. 3. Represents a drum-head or similar vessel with the filling aperture A
therein and the two small holes b and c cut out of the drum-head K to receive the
hooked clip or jaw (No 2) and the stop or pin (No 3).
Figure 4. is a plan of the reverse side of a lid or closer in one piece with the
small inverted ear (No 1) and small aperture d cut therein to receive the stud-bolt
(No 4) the nut (No 5) and the pin (No 6).

page_text: Figure. 5. Represents a side view of a drum-head with the lid or closer fixed in
its position by means of the internal ear stud bolt nut and pin.
Figure 6. Represents a drum or similar vessel with the filling aperture A the
groove or hollow e and the stud or bolt (No 4) rivetted to the head K of the drum
or vessel, with the nut (No 5).
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1st The lid or closer in Figure No 1 the same not having any projecting flanges
or any flanges visible from the obverse side thereof but possessing on the reverse
side thereof the ear (No 1) the hooked-clip or jaw (No 2) and the stop or locking
piece (No 3) in combination with the apertures or openings set forth in K Figure 3
and to be used for the purposes and in manner hereinbefore stated.
2nd The filling aperture A in Figure 3 having no recess at any side or part
thereof and the holes b and c in K Figure 3 substantially of the shape position and
description set forth and to be used in combination with the lid or closer in
Figure 1 and for the purpose and in manner herein before stated. The filling
aperture A being formed either with or without the groove e in K Figure 6 for
the reception of adhesive or other sealing matter.
3rd The lid or closer in Figure 4. with the ear (N°. 1) and aperture D in com-
bination with the aperture A stud bolt (No 4) nut (No 5) and pin (No 6) in K
Figure 6 and to be used for the purpose and in manner hereinbefore stated.
4th The filling aperture A and stud in K Figure 6 substantially of the shape
position and description and to be used in combination with the lid or closer in
Figure (4) for the purpose and in manner hereinbefore stated, such filling aperture
being formed either with or without a groove near the edge of K thereof for the
reception of adhesive or other sealing matter.
