This invention relates primarily to novel and automobile provided with an upwardly extending
pipe Il through which the oil for the crank case

has for its object to provide a quickly removable
method _of mounting the iilter so that it may be
installed, inspected, or replaced with a minimum
of eiiort and time consumption.
Another object is to eliminate the usual mount
ing clamps or brackets commonly used for at
taching the niter to the mechanismvby mounting
the filter directly by a quick detachable means to
the oil nller pipe or other opening in the engine or
mechanism housing communicating with the oil
reservoir. Theiiltermaybeanintegralpartof

_
A special object is to provide an oil filter which
20 can be readily installed by anyone on an engine
'
which has not been provided with a. filter. ,
.
Other advantages over the commonly accepted
methods of oil iilter installation will also be no
ticeable in this speciilcation such as provid
ing a simple means oi inspecting the flow of oil
at the filter outlet while the mechanism to which
it is‘attached is in operation, although this is not
essential to the invention.
Another object. -of this methodvof mounting is
to reduce to a minimum the amount oftubing nec
essary to make the illter installation inasmuch as
the filler pipe or other opening comprising the
mounting means constitutes at least a portion of
the discharge pipe of the filter. From the fore
d going it will be seen that this method of mounting
a filter very greatly reduces the cost oi' construe
tion and installation.

ter casing II containing any convenient type of‘
filtering unit. >The oil supplied to the iilter enters
through the tube Il and is discharged through the
pipe I2 shown in Fig. 2 as being within the sup
porting pipe Il but spaced therefrom in order
that the pipe Il may be vented if desired.
A resilient sleeve I4 telescopes with the pipe Il
for securing the filter casing in position. As illus
trated in Figs. 2 and 4, where it is desired to vent
the pipe III, portions of this yieldable sleeve I4 are
bent up at I5 to constitute spacing lugs on which
the weight of the ñlter _casing Il is borne, or
transmitted to the top of the pipe IU. The por
tion of the sleeve I 4 from which these lugs were
stamped therefore provides openings II' through
which the pipe I0 is vented. If no vent is desired 20
the lugs may be omitted.
In Fig. 4 is shown one type of construction in
which the sleeve I4 is provided with a slit or
opening I4' to provide a desirable yieldability.
A guard or projecting skirt portion I6 is se
cured to the base of the ñlter casing to extend
over the vent openings, if provided, at the top of
the pipe 'I0 to protect it against the entrance of
dirt and foreign matter getting into the oil.
The oil pressure in the system is sutllcient to
force the oil up through the tube I3 and through
the illter Il.
The sleeve I4 provides a quick detachable con
nection between the filter casing and the pipe so
that when fresh oil is to be poured into the ñller
pipe I0 the filter casing is disconnected from the
pipe, the supply tube lIl being ñexible and long
enough to allow such quick detachment of the
filter casing.
