The present invention ,relates to apparatus for removing the `oil and sludge from the crank case of an internal combustion engineand Athe invention more spe-cically pertains to such apparatus in the form of a portable unit which 'may be moved to a position adjacent a motor vehicleV so that the oil and debris may. be pumped from the crank case in a matter of approximately a minute Without removing the drain plug and without arranging the motor vehicle over a pitor on .a lifting .-rack.
An object of the invention is to provide apparatus in the form ofv a portableunit which may be employed to pump therroil and sludge from the crank case of .an internal combustion engine outwardly through thev opening which normally accommodates the measuring stick and to deposit s such liquid into a tank carried by the apparatus.
Another objectof theinvention is .to provide such a portable unit with conduit. connections which will permit ushing oil to be introduced into the crank case and thereafter pumped outwardly through the measuring stick opening-and again supplied to the llingy opening ofthe-engine crank case so that the ushing oil will be circulated by the pump toV more thoroughly cleanse the crank case and associated parts'of the internal combustion engine. l A more specic object of the invention is to pro- Y vide a portable unit including a tank which is removably mounted within a `housing carrying the pump and a motor therefor, including an arrangement for accommodating a plurality of tubes for 1 use inA diierent size measuring stick openings, and a housing structure for enclosing at least one of the exible conduits connected to the pump and" which may be withdrawnfrom the housing;
A still further and more detailed object of the invention is to provide a novel type iioat assembly in association with the tank, cooperating with part of the signal meansso that the tank may be removed from the ',vhousing 'and reintroduced therein without disturbing any of the parts of the float assembly. 5 u

The apparatus herein vdisclosed represents improvements over the features of my co-pending application, Serial No. 645,762, led February 6,
1946 which matured as Patent No. 2,552,749, May
5, 1951. Thefpresent vinvention is directed to features of the housing'yando'ther improvements in apparatus for removing oil andV debris or sludge from the crank case of an internal combustion engine. The invention pertains to a portable unit which may be moved to aposition'adjacent a motor vehicle in a filling/station or to a position adjacent the engine of a bus or truck, and includes a motor driven pump which may be operated to draWJthe oil, sludge and cleansing liquid from the crank 1case preparatory to the introduction of a fresh supply of lubricant to the reservoir provided under the crank shaft of most internal combustion engines. The liquid is withdrawn from the crank casethrough the measuring stick opening and for this purpose a tube is employed at the end of afflexible hose extending from the inlet side of the pump. The tube is of such small diameter asv to extend to the bottom of the crank case through the measuring stick opening and the pump maybe 'ai gear pump which upon oper-A ation with the liquid oil passing therethrough creates, a vacuum in' the tube extending to the wardly therethrough and out yof the crank casef through the measuring stick opening ata, rather high velocity and through the pump intol a `tank carried by the portable unit. The apparatus in actual use has been found to remove more of the sludge and debris from the crank case than `is removed by an ordinaryY draining operation and this advantageous result jamearsfto iiowgfrom the rehandle in operative association with the cabinet structure. The-handle 62 is thereby arranged at the back of the device and this element serves as vmeans for manually moving the unit on the may be secured to the lid 63. A depending flange'- 66 is provided along the perimeter of the lid which overhangs a vertical flange Vformed around the top portion of the casting 46. Resilient gaskets or; resilient pads (not shown) may be provided to prevent chattering and to reduce the noise when the lid is closed.
The housing or cabinet structure includesa partition 6'I spaced from the side wall I6 and arranged substantially parallel with the iiat portion thereof. This partition may be provided with a ange 68 at its forward edge which may be welded or otherwise secured to the front wall I9 of the housing. The partition-61 terminates at the rear edge adjacent the door opening 2| and may be secured to this part of the housing and to a flange 69 formed integral with the curved corner portion I7. The partition 61 may be welded to the flange 69. This partition extends from the bottom wall 23 upwardly to a point adjacent the top of the side wall I6 and provides a rather large space or compartment I within the cabinet. A similar partitionY 1| is provided on the opposite side of the tank 22 and may be Welded to the front wall I9 along a flange 12. This partition 'II is also joined to the rear part of the cabinet adjacent the arcuate portion I2 by means of a flange I3 as shown in Fig. 4. The partition H is spaced from the side wall II and provides a compartment '|5'between the partition 1I and the side wall II. The partition '|I carries a horizontally arranged channel member 'I4 on its inner face which may be welded thereto and which -provides a guide for the tank 22. This channel member reinforces the sheet metal partition 'II and providesl an abutment for preventing lateral shifting of the tank 22. A similar horizontally arranged channel member 'I6 is provided on the inner surface of the partition 61. This channel member '|6may be welded to the partition and cooperates with the other abutment '|-4 to provide guide means for the tank 22 during the insertion and withdrawal thereof into and from the housing.
A platform 8| ismounted within the housing near the top thereof. This platform may take the form of a plate mounted on anglebrackets 82 welded respectively to the partitions 6'I and 1|. The platform or plate 8| may be secured to these angle brackets in any suitable manner such as by means of bolt and nut assemblies 84.` A motor 86 is mounted on the platform and drives a pump 81 of the gear type. The shaft of the motor may be 'connectedto the shaft of the pump through a suitable flexible coupling and it is within the contemplation of the invention to mount the pump directlyon the motor itself.
The motorf86 Vis supplied with electric current through a cable 88 provided with a male type connector 89 at the end thereof, as shown in Fig. 1, This cable`88 extends through an opening proa rather long length of cable 88 so that this conductor may extend tof a suitable source ofv supply.
Thecable 88 is kconnected to a switch 9| having an operating handle 92.I This switch is mounted on one of the vertical Walls which define the recess 53 in the corner ofthe casting 46. The Vswitch operating handle 92 extends lthrough the wall of the casting and maybe manipulatedfrom a position outside the housing. The recess and adjacent portions of thecasting shield the operating handle 92 and prevent vdamage thereof, or inadvertent manipulation of this main operating switch. The cable and suitable electrical conduc- Mtors extend from the switch 9| to the motor and other parts'of the electrical system. The closure lofthe switch 9| provides for energization of the motor 86 to drive thevpump 81.
A hose or flexible conduit 94 is connected to the inlet side of the pump and thishose is constructed of a material which-will notl be attacked by lubri eating oils or the like. The hose 94 extends into i the space or compartment 'I0 between .the partition 61 and theV side wall I6, and will c oil itself therein somewhat in the manner as illustrated in Figs. 2and 4. This'rather long length of hose permits the unit to be positioned at some distance from the internal combustion engine and the hose may be withdrawn from the compartment 'I9 at the side of the cabinet. The free end of the hose extends through an aperture in the horizontal wall ofthe top memberA 46 which forms a part of the recess 55 arrangedabove the arcuate corner I3 of the housing. The'free endjof the hose 94 is provided with a female Acoupling member 96. as shown in Figs. 1 and 2,. This coupling part 96 is adapted tonestle within the recess 5 5 as 'shown in dotted lines in` Fig ."2 and is 4sufficiently large to prevent the freerendofthe hose 194 passing derstood that the hose may be withdrawn through theaperture in thebottom wallrof. therecess 55.
The bottom wall` of the recess 5`|Afis provided withja plurality of apertures'.` Inthe yembodiment illustrated theseap'ertures each accommodate a tube 98 which is adapted tofbe inserted K in the measuring stick opening I|0 Iof the crank case. These tubes may be of various sizes and are shown in Figs. 1 and 44., Each oflt'the tubes 98 is provided with a'male couplingA part '99 which is adaptedto ilt into the female coupling member 96 and at the same time provide a vacuum tight connection .betweenthe hose 94` and anyone of the' tubes 98. These'tubes depend into the compartment'l between the partition 6'I and the sidewall I6. The m'ale'coupling parts 99 are somewhat larger Ain dimension than the apertures in the bottom wall 4of the recess 51 so that these tubes and the male coupling parts ,.99 are nestled in. the recess5`| wherevthey do Vnot protrude materially beyond the 'outline of Lthe cabinet.
y The tank '22 is'fg'enerally rectangular shaped t in crosssection and is providedwith'afemale f coupling `member which maybe attached Yto the top wall of the'tank and communicating with the'interior thereof. A flexible hose |02 extends Afrom the'outlet sideof the pump 3'1 and'is provided with a male coupling part |93 at vided -in the horizontal bottom wall of the recess y ing coiling oran indiscriminate arrangement of the free end thereof. Y Thereby thejhose |92 may bedetached from 'the`tank22. The hose lv[|32 is of greater length than is necessary to provide a conduit connection between the dischargeA side 'of the pump andfthe tank 22.5 This lunusual length is provided'for the purpose :of disconnecting the free endof the hoseV |02 from :the tank pressure withi'n the: hose line 94 'imamrecessf52. Thefxnaiej plug is"`then introduced into a conventioaifrle 'socket providing a supply 'of e1ectrca1'-energy'to the Switch 9 1 ALtube 98 `isj then selected .and may be withdravrnY from a position' 'within 'the compartment 10 "at [the side of the 'partition' 161. ,The male e'oiiplirg' part 99 is then readyjornnsertnihf thefferrle crank .oseff after L thefinesuring Stick hals been Cury. This vva'cum'n"mores themoifahdfsludge -produced amounts to approximately twenty eight inches of mercury and at this pressure four or ve quarts of oil and sludge are removed through K the relatively long suction line ina matterr of approximately one minute. The gear pump pro- Y vides the'unobvious result of providing a vacuum in the suction line amounting to approximately twenty eight inches of mercury when the ,gear
teeth` are coated with a film of'sludge and-oil.'
It will beappreciated that this is ian unusually high vacuum for a gear'pum'p which in the dry condition willproduce a vacuum corresponding only to about five inches of mercury. f i
While, the invention described with reference to specic structural features, andwith regard to particular organizationalv arrangement, it will be appreciated that changes maybe made in the various elements and in thewoverall organization. Such changes and others mayxibe; made without departing from the spirit and scope of the inventtion as set forth in the appended claims.
