(Cl. 21d-184) This invention relates primarily to novel and automobile provided with an upwardly extending pipe Il through which the oil for the crank case improved means or methods of attaching a lulu'i cating oil iilter to an internal combustion engine is supplied'. Detachably supported on the usual or other mechanism having a recirculating lubri 5 catingsystemsuchasairccmpressorsetc.and 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 'themechanismormaybeconstructedasan ac ce«$90111 to mechanisms in prior use. _ 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. Referring to the drawings - ' Fig. 1 is a perspective view showing one form 40 of the invention. 45 . 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. ‘ 'I'he engine is usually stopped before separat- ’ ‘ Fig. 2 is a view-.partly in section showing the manner in which the filter of Fig. 1 is mounted.

Fig. 5 shows a ñlter with a hook-like out let ’ ing the filter from the pipe III when new oil is to be poured into the crank case or when a illter is to be replaced, nevertheless there will usually be some oil in the illter which has not entirely drained out and to guard against oil dripping gh 5 from the discharge pipe I2 on to the engine or elsewhere we provide a drip cup Il as shown in Figs. 2 and 4 secured around the ñlter discharge Fig. 6 shows a swivel screw cap connection for l pipe I2 but spaced from the sleeve I4.
