Thepresent invention isdirected to apparatus; for quickly removing the lubricating oil. from the 1 crank case of an internalicombustion. engine such. as the motor of: an automobile; The apparatus is: adapted for use in servicing. motor: vehicles such. as is customarily: provided bya. filling station or by. a. shop servicingafieet ofv trucks, busesor. the; like. Theapparatusis alsoadapted to there-' moval of oil from; engines on board boats. One; of the characteristic featuresof the apparatus. is that of removing the oil. from thecrank case, in. a relatively shortperiod of approximately a. minute whereby the usedoilmay bezremoved. and. the crank case refilled withfresh lubricating oil. in. a relatively short period so that. the motorist; may. again obtain usezofz thecvehicle withoutrthe. necessity of placing thercar. over a drain pit or on. an elevating. mechanism for:the.;drainage of the. oil. from a. crank cases.
The invention further; pertains to the removal. ofv the crank caselubricant: through an. existing; opening. in the engine assembly or through an. openin which the motor. car. manufacturer has provided in the motor. such. .as the, breather opening. or the measuring. stickv opening. Theinvenr tion. is accordingly adaptable. to; all. types of) engines in. that the crank; case lubricant is with drawn. through, the; opening; normally accommoe 3 erally at I!) atank; which may be of any appro:
priate size and shape and the, illustrated em; bodiment is substantially square crossseotion. and is. adapted to hold: approximately thirty. orthirty-five gallons of. liquid. The tank is prefer-=- ahly of such. capacity, that. it may. be portable;
n v c nve n y shifted. from on place; o: 4 other by an attendant even. when the tank. is. filled with. liquid It. isfor this purp se. th t he: tank. is; suppor ed. by a plurality of. wheels. 11
up; which may be in: the. form. of. casters. whereby:
the direction of movement of the tank may be readily altered. The casters or wheels l2 may be of a type which may be rolled with a minimum of effort including anti-friction bearings and the peripheries of the wheels may be furnished with resilient material such as rubber or a composition which is not attacked by hydrocarbon materials. The tank assembly includes a handle M at the rear portion thereof which extends across the width of this receptacle. Thus the tank may be conveniently moved and guided to any desired position.
' The tank is closed at the top by means of a top wall l6 and this top member provides a base for supporting the pumping mechanism hereinafter described. The rear wall l8 of the tank is preferably arranged transversely of the apparatus at a point short of the rear extremities of the side walls 2| as shown in Fig. 2. A recess 22 is accordingly provided between the side walls 2| at the rear portion of the tank. The top wall I6 is hermetically joined to the sides and end'walls, of the tank and is preferably formed of sheet metal of substantial thickness so as to support the pumping mechanism and the controls therefor on the top wall. The bottom l of the tank is provided with a drainage opening which is normally closed by any suitable means such as a removable threaded plug H).
In the illustrated embodiment an inverted channel member 24 is mounted transversely of the tank and may be welded or otherwise secured to the top 5. The inverted channel member 24 provides a passage or open space thereunder for accommodating electrical conductors which lead to the motor and various control switches. Any
. type of pump may be employed for withdrawing the oil 'from the crankcase of an internal come,
by means of a coupling 32 which is preferably.
of the type to provide a driving connection between the two shafts even though there is' some displacement in the axial alignment thereof. It will be apparent; however, that other types of driving connections may be employed between the pump and the motor shaft.
In carrying out the invention the oil and sludge are withdrawn from the crank case of the engine by the pump 26 and delivered into thetank l0. Accordingly, the discharge opening 34 of the pump 26 is in open communication with the interior of the tank W by means of a hose or flexible conduit 36. It will be noted that the hose 36 is longer than necessary to provide a connection between the discharge opening 34 and the interior of the tank Ill and the purpose of this relatively long conduit 36 will be more apparent as the disclosure proceeds. The inlet opening 38 of the pump 26 is also provided with a flexible hose 4| which extends downwardly from the pump through an opening in the top I6 and into the recess 22. thereof a tube 42 which is of such a small diameter as to be readily inserted through the existing measuring stick opening of an internal combustion engine. The eduction tube 42 is adapted The hose 4| carries at the end.
to extend to the lowermost-part of the lubricat ing holding case as shown in Fig. 7 so that all of the liquid oilv and sludge may be withdrawn through the measuring stick opening. Inasmuch as the lower end of the tube 42 is adapted to engage the bottom of the crank case, the lower end is notched or bevelled as illustrated at 44 to permit access of a lubricant and sludge tothe interior of the tube and the. hose line 4|.
In carrying out the invention, the tube 42 is introduced through the measuring stick opening 43 as shown in Fig. '7 after the measuring stick 45 has been removed therefrom. The tube 42 is moved downwardly through the measuring stick opening'until the lower end engages the bottom of the crank case and lowest portion of the sump 55. The motor 28 having previously been started and the pump 26 being in operation, the vacuum createdin the hose line 4| will withdraw the oil and sludge from the crank case and deliver this liquid material through the line 36 into the tank I0. The connection between the hose or conduit 36 and the tank I0 is one of a quick change coupling type which includes a make part. 46 as shown in Fig. 6 which is threaded into the top I6 of the tank and a detachable female part 41 which is connected to the tube or conduit 36.
A quick change coupling is also provided between the tube 42 and the line 4|; The apparatusincludes a pipe 5| extending downwardly in the tank ID to a point near the bottom thereof and. this pipe is in open communication with the 'male part 46a of a' quick change coupling. Thus when r the tank I0 is filled with oil; the tube 42 may be readily removed from the hose 4| and this hose may'then be connected to the pipe 5| and' the male part 46a of'the quick change coupling The hose 36 may 7 associatedwith the pipe 5|. be removed from itsconnection with the tank and this'conduit maythen be employed to 'disto engines having different sized openings and engines requiring eduction. tubes of greater lengths. The sheath 49 is mounted at thelower end within the recess 22 and extends outwardly and upwardly therefrom and is attached to the top |6 bymeans of a bracket 53. g
' The pumping mechanism mounted on the top of the tank I0 is adapted to be enclosed within a hood shown generally at 56. The hood 56 is hinged at the lower rear edge thereof by meansof a plurality of hinges 51. The hood 56 may be detachably retained in a closed position by means of a clasp assembly shown at 58. A handle 59 is povided for manual manipulation of the hood 5 The apparatus includes-means for indicating various conditions of operation of the apparatus and such indicating means inthe embodiment illustrated are in the form of lamp assemblies carrying appropriate legends. .These lamp a'svsembliesare mounted in an inclined front poras shown in Fig. 4 is-energized whena vacuumoperated switch "diagrammatically illustrated at 63 is closed. "This switchis en'cased'within ''a--i'el'-- atively small housing 64 asshown in Fig; 3. The

inclined portion BI of the hood andupon closure thereof themotor-28 isenergizedand starts. The
lamp fiais simultaneously energized and indicates that. the. motor is in operation. The signalling system includes means for indicating that the tank It isfull and this indicating arrangement includes a. lamp 7 l. The tank in is provided with a float operated switch diagrammatically represented at 12 and arranged within a casing 13.. Whenthe float 74 shown in Fig. is raised, the switch 12 is closed to energize the lamp H and thereby indicate that the tank I0 is full. The apparatus is provided with electrical conductors 16 in the form of a flexible insulated cord connected to a male fitting l"! which may be plugged into an electrical outlet.
In carrying out the invention, the portable tank l0 which supports the pumping mechanism may be conveniently rolled on the casters or wheels l2 to a position adjacent a motor vehicle or an internal combustion engine. The flexible conductors '16 are preferably of such length as to extend to a convenient electrical outlet. Thereafter upon closure of the switch 69, the motor 28 is started and the pump 26 is set in operation. The indicator lamp 68 is energized to show that the motor and pump are in operation. The measuring stick is then removed from the measuring stick opening of the engine and the tube 42 may then be inserted through the measuring stick opening 4E! into the crank case as shown in Fig. 7. The tube 42 is moved downwardly until the lower end thereof engages the lowermost part of the sump 50. The vacuum created within the hose line 4! will then cause the switch 63 to close whereby the lamp 62 is energized to indicate that the pumping operation has been initiated. The oil will be discharged through the conduit 36 and pass into the tank Ill.
It is to be noted that some engines are provided with relative large openings for the measuring stick and fresh oil is introduced into the crank case through such openings. The tube 42 or a larger tube may be readily inserted through the oil introduction opening whereby the dirty oil may be withdrawn through an existing opening in the engine assembly. In some cases the eduction tube may be inserted through the breather opening.
It is desirable to remove the oil and sludge as quickly a possible and it is for this purpose that the pump arrangement is so designed as to remove the oil through the relatively small tube 42 Within a period of approximately one minute. If desired, the crank case may be provided with flushing oil and this flushing material likewise removed through the tube 42. Under such circumstances it may be desirable to remove the hose 36 from coupled association with the tank i0 and to deliver the flushing oil into an auxiliary tank or receptacle. After repeated removal of oil from various engines, the tank ID will be filled and the float 1.4: will. actuate the switch; 12 to energize the.
lamp; ll and-.indicatethat the. tank In isiull, The
tank In may then be mptied by attachin the hose 4| to the coupling part 45a. and the pump. 2.5; may then. be. employed. to withdraw. the oil from: the; tank. 1.0.. Duringthi pumpin opera.-
