COMPLETE SPECIFICATION.
Improvements in Cans for Holding Liquids such as Petroleum,
Benzine, and such like,
We, FERDINAND HENZE, Chemist, and JACOB COHN, Manufacturer, both of
Salzkotten, near Paderborn, Westphalia, and WILHELM HEINRICH SCHMITZ,
Manufacturer, of Dortmund, Westphalia, Germany, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticulary described and ascertained in and by the following statement: -
This invention relates to a can for holding explosive liquids such as petroleum,
benzine, or the like, which is so made that when liquid is being poured out a
flame cannot penetrate the interior of the can and set the contents ablaze. The
can is further so made that when liquid is being poured into it any overflow
through the air inlet passage cannot trickle down the outside of the can but col-
lects in a receptacle which is arranged round the air inlet.
The improved can is illustrated in part section on the annexed drawing.
The can, which is made, in the usual manner, of tin or other suitable
material, has, as usual, a spout b, a mouth c through which the liquid is poured
in and a closing cap d. Underneath the opening c an air admission opening f
is, made in the wall of the can. This opening f is provided with a sieve gover
which, at the outside, a protecting cover h is fitted.
The protecting cover is, as shown on the drawing, of bowl shape and is made
with an opening at a suitable position such as at the top (see the drawing).
For the purpose of preventing the contents taking fire through the mouth c
a tin box can be secured therein. The wall of the box is perforated and the
pressed out metal of the perforations is made to form teeth or points k which
project upwardly and serve to protect the sieve g², which surrounds the box i,
from injury.
When the liquid is being poured out of the can it passes through the spout b
whilst air is admitted through the openings h¹, f. Should the oil take fire the
flames can only ascend the spouts as far as the conic sieve g¹ fitted at the bottom
of the spout, and are therefore prevented from setting fire to the contents of the
can.
When the liquid is being filled into the can through the mouth c, from which
the cap d has been removed, it splashes upon the bottom of the box in such
manner that a part frequently escapes through the opening f. Owing to the bowl
shape of the protector ½ the escaping liquid is collected therein and runs back
again into the can so that the external surface of the can is not wetted with the
liquid and the fingers of the person handling the can are not, as a consequence,
soiled or wetted with inflammable liquid.
By fitting the conic sieve g¹ at the bottom of the spout it is preserved against
injury from the outside.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
consider novel and desire to claim is:-
1
A safety can having besides the usual filling in and pouring out-onenings,

page_text: an additional air-inlet opening protected by a sieve, substantially as herein before
described.
2. A safety can, such as claimed in Claim 1, wherein the air inlet (f) is covered
by a sieve (g) and protected by a cover of bowl shape which serves as a means
for collecting liquid splashed through the.air inlet, substantially as hereinbefore
described.
3. A safety can, such as claimed in Claim 1, wherein the spout is provided
at its lower end with a sieve g', substantially as and for the purpose set forth.
4. A safety can, such as claimed in Claim 1, wherein the mouth has a sieve (g²)
fitted in it said sieve being strengthened by a perforated box (), substantially as
herein before described.
5. The construction of safety can substantially as hereinbefore described and
shown on the drawing annexed.
Dated this 13th day of September 1899.
