' 'I‘he interior of the container 2|, that is, the

of said container, is preferably substantially com
pletely filled with a mass of purifying material
which may comprise a body of fibrous material
such as paper pulp or a porous mass of decoloriz
70 ing material such as fuller's earth or the like, or
mixtures of such materials, dependent upon the
particular purifying problemy at hand. 'I‘he side
wall 2 la of the container 2| is provided with suit

upper end of -the container I, somewhat afterthe
manner shown, but thé specific location of this
40

'In assembling the removable purifying element,
I may utilize> a conventional tin can closed at one 45
end and` open at'the other, an openingV 26 .being
provided- for the closed end of the can, which
closed end will constitute the wall 21.. The sock
2l is then inserted within the opening 26 and the ;
open end thereof splayed out over the said lower 50
wall after the manner shown in Figs. 3 and 5, a
center-perforated conventional can lid 2l being
then rolled into engagement with the rim of the
can over the splayed ends of the sock, to engage
the rim 21a of the wall 21,.a'nd'the central portion
of said lidv being rolled inwardly as above described-
to securely' engage the sock at the position of tlíe
openings 28 and 29. A mandrel may then be in~
serted within the sock 2l, simulating‘the posi
tion of the sleeve | I, the helical support or spacer
Il placedin position against the side wallf2|aY
of the can, and the screen 35 and the membrane
3B placed in position againstthe spacer '34. :The
space between the membrane I6 and the `sozl: 24
is then filled with the purifying body 33, and the
upper wall 22 then placed over the openend of the
can and rolled into .-secure engagement with~the
upper edges of thev side wall 2|a . ln'fth‘e same
manner as the ordinary tinfcan is capped in a

withdrawn, and, assuming the holes 32' to’have

The new
purifying element is placed within’ the container
I by a reverse procedure, and the entire'operation
of removing and replacing the> purifying element
may be’ carried out in less than a; mìnute’s time.
The device is primarily adapted for' use on in
ternal combustion engines, and the facilerepl'ace
ment of the purifying element makes it possible to
40 remove and renew the puriñer without the aid
of skilled labor. A suitable bracket or the’ like
-may be provided as shown at 5I, to'secure the
purifying deviceto a suitable supporting structure
adjacent the engine with which the device is as
45 sociated, as will be apparent to one skilled in the
art.
In the above specific description of the present
device I have considered that the cylindrical con
tainer I is disposed substantially vertically in use.
50 It will be appreciated that the device might equal
ly well be disposed at an angle to the vertical
'Without departing from the spirit of the inven
tion. -Furthermore, while the liquid discharge
member II is shown as extending upwardly from
55 the lower Wall of the container I, it will be ap
preciated- that the construction may be inverted,
or the member II may be secured'to the upper
,wall 4> of the device, within the contemplation
of this invention. 4In general, it is- more con
"60 venient to provide both the liquid inlet and outlet
connections on the relatively fixed portion of the
device, as upon the container I as shown, where
by it is not necessary to remove such» a connection
in the operation of replacing the removable puri
65
fying element.

The removable purifying element is most ad
vantageously formed of circular cross-section,whereby conventional canning machines may be
utilized in assembly thereof, but at the same
70 time it will be realized that the specific crosssectional configuration of the element is a matterV
of choice, and as far as the operational charac
teristics~ of the device are concerned, a cross
section other than circular may be employed.
