A New and Improved Receptacle for Safely Storing Calcium Carbide.
FREDERICK SANSOM THORN, Gas Engineer, of No. 114, Vassall Road, North
Brixton, Surrey, and CHARLES HODDLE, Gas Engineer, of No. 84, Arthur Road,
North Brixton, Surrey, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to an improved receptacle for conveniently storing
calcium carbide so that it is quite secure from water or moist atmosphere.
To accomplish this we provide a receptacle of any suitable size or shape and
of any suitable material, preferably galvanized iron, with a circular opening at
top made with a double neck or collar formed by two rings the outer ring being
of larger diameter than the inner ring 1ound the opening to the receptacle so as
to form a groove of suitable width and depth all round. This groove is filled
with any suitable luting such as oil or spirits but preferably dry silver sand.
We also provide a lid or covering with a double collar also circular and adapted
to fit over the double neck of apparatus in such a manner that the inner ring
on the lid fits between the two rings on the receptacle the outer collar on lid
fitting over the outer ring of receptacle so that with the liquid or material in the
groove referred to and the lid in position the apparatus is both air and water-tight
so that no water or moisture can enter neither can the smell from its contained
calcium carbide escape. For further security the said lid is also provided with
suitable catch or lock-up fastening.

FREDERICK SANSOM THORN, Gas Engineer, 114, Vassall Road, and CHARLES
HODDLE, Gas Engineer, 84, Arthur Road, both in the County of London, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in apparatus for storing calcium carbide
and has for its object to provide a simple and efficient apparatus whereby the
calcium carbide is protected in hermetically sealed vessels.

page_text: According to our invention we provide a cylindrical or any suitably shaped
vessel partly covered in by a dome shaped top. This top has an aperture for the
admittance or withdrawal of the calcium carbide and two rims are provided,
one fixed on the edge of aperture and the other fixed at any suitable distance
outside it, in such a manner that a luting may be inserting in the intervening
space or channel.
A lid or cover is also provided, also having two rims affixed, one being suffi-
ciently large to overlap both the rims affixed to the receptacle, and the other of
a suitable diameter to fit into the luting, in channel, between the two rims, on
said receptacle, in order to thus form an hermetically sealed joint.
In, the accompanying drawings,
Figure 1 is an elevation of apparatus constructed according to our invention.
Figure 2 is a horizontal section on the line d d of Figure 1.
a is the body of calcium carbide receptacle or holder and bis the lid or cover.
a¹ a² is the double collar on receptacle and c is the channel for luting. ¹ being
the inside collar or rim on lid or cover which sits into the luting, when closed,
and thus forms an air-tight joint.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is: -
1. The receptacle or holder with double neck, forming channel for luting,
substantially as described.
2. The lid or cover with two rims or collars affixed the inner one being
adapted to drop into the channel containing a luting, substantially as described.
3. The combination and arrangement of parts forming the improved apparatus
for storing carbide of calcium hereinbefore described and illustrated in the
accompanying drawings.
Dated this 28th day of October 1897.
