ToaZZ whom it may concern:

Be it known that I, JASPER V. CARSON, a citizen of the United States, residing at Gunwald, in the county of Lucas and State of Iowa, have invented a new and useful Oiling System for Automobiles, of which the following is a specification.

The object of my invention is to provide an improved oiling system especially adapted for use on a well known make of popular priced automobiles; and to prov de two forms of the invention, one of which may be built into the engine apparatus as it is manufactured; and the other being an accessory adapted to be applied to a completed car. I attain the objects of my invent on by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical sectlon, partly in elevation, of the invention bullt into the motor system.

Fig. 12 is an enlarged detail view of parts shown in Fig. 6.

' .Like numerals designate like parts in each of the views.

Referring/to Figs. 1,5 inclusive of theaccompanying drawings ,(andso far as the numeralsv are-applicable, to the remaining views), I provide a tank 1 mounted on the to the filling spout 9. In the lower end of V the rib 5 is an oil passage 11, with which the oil passage 20 in spindle 17 alines when member 17 is in the position shown in F 1g. 2, and in which position passages 11 and 20 are both in alinement with the passage or connection 12 which is in communication with oilsupply pipe 13. Oil supply pipe 13, disposedasshown in Fig. 2, 1s diS- posed within conduit 14, which is of larger diameterand to which it is attached in spaced relation by a plurality of suitable braces or spacing members 25, as shown-0n an enlarged scale .in Fig. 5, there being any suitable requirednumber of these memhers for supportlng pipe 14 in spaced relation to pipe 13. .Theouter pipe 14 is pro vided with perforations15 at its upper end, and with perforations 16 at its lower end.

Referringto Fig. 2 ,1 provide a nut 18 attached to the lowerend of spindle 17. I also provide a suitable spring 19 interposed between nut 18 and base 3 of the oil tank 1, whereby -to-normally hold spindle 17 in its lowermost position in which oil passage 20 is alined with . oil passages 11 and 12. Perforations 15 at the upper end of the outer pipe 14 are for the admission of air into the upper .end of theclosed pipe l; while perforations 16 at the lower end of pipe 14 are for the admission of oil to that element.

Referring to Figs. 3 and .4; I provide an opening 21in the upper end of tank 5 alined withoilfilling passage v22 of the filling arm 8.; through which oil is supplied to tank 1. I prefer to provideasuitable recess 23 in the casing of tankl, in which recess is mounted ,a suitable glass oil gage 24 for vdeterminlng the quantity of oil in' the tank by an inspection ofthe gage 24. Tank 1 is of semi-cylindrical shape as shown in Figs. 3 and it, and iscast integral with the fly-wheel covering. The plate l3 and a suitable ,gasket interposed between the portion of plate thatengages casting 2 provides the airtight closure fortheoil tank 1 of which it is the base. Tank 1 extends up to the bottom of the coil box and is of the same width and thickness except for the recess for the glass gage. Tank 1 is to be rounded on the upper corners and edges, preferably. It will hold about three quarts of oil. It is slightly concaved on the front side to accommodate the end of the motor. A suitable indentation 7 for the reception of filling spout 8 is provided as shown in Fig. 3, and from which seat the spout may be swung to the position shown in dotted lines in Fig. 3, for convenience in filling the tank, the filling spout being pivotally or swingably mounted at one end as shown. As indicated in Figs. 2 and 3, cap 10 is provided with a small opening or perforation to permit of the escape of air.

Referring to Fig. 2 the coil spring 19 normally holds spindle 17 snugly seated in the position shown in Fig. 2, with passages 11 and 20 alined, and the spout 8 is seated in indentation 7 flush with the tank. When filling spout 8 is swung outwardly, for purpose of filling, to the position shown in Fig. 1 and in dotted lines in Fig. 3, the lower end of the spout alined with opening 21 in the upper end of the tank and the opening 20 in the lower end of spindle 17 is moved out of alinement with passa e 11 to prevent oil fiowing'into pipe 13. ipe 13 which is attached to the connection 12 by a suitable watertight connection, extends down to the a bottom of the transmission case to a point midway up and down between the two pet cocks on the outside of the transmission case, but with the lower end in the center thereof. This pipe 13 (and spaced pipe 14) hangs just behind the flywheel and in front of the transmission bands, and bends around the transmission ears in reaching the bottom of the case. Fipe 14 is preferably fastened by a collar or braces 25 to the smaller pipe 13 and extends to the extreme bottom of the transmission case and is open at the bottom. It is also perforated with 4; inch openings 16 up to almost the level of the pipe 13 which it incases. Gage 24 is suitably connected with the interior of tank 1 to permit the oil to flow freely into the gage, which is mounted in the customary manner. WVhen oil is consumed to a point where its level falls below the end of the small pipe 13, air is admitted through the perforations 15 at the top of the largest surrounding pipe 14, and the air flows upward through pipe 13 in bubbles to the tank above which releases the oil until it reaches a level just above the lower end of the inner pipe 13. The oil is thus kept at a uniform level in the transmission case at all times regardless of unevenness of roads or other conditions. This is an extremely important factor in the operation of the popular car to which this invention is particularly adapted, as too much oil overheats the motor and fouls and breaks the spark plugs, reduces power, and promotes the formation of carbon in the motor rapidly; while on the other extreme a too small amount of oil sup ly is more disastrous and expensive. l/ y invention will give the numerous owners of this type of car absolute freedom from one of the most annoying cares, for one filling of the tank will be sufficient for 400 or 500 miles without further attention.

' Referring to Figs. 6-12, in connection with the details of members 13 and 14 shown in Figs. 1 and 2 there is disclosed a modified form of my invention adapted to be applied as an accessory to the hereinbefore described type of car without any essential modification of its structure as now turned out by the factory which built the car. In this form of the invention I provide a tank 26 which is placed on the left side of the motor under the hood, the tank being made of heavy glass or other suitable material so that the driver may glance at the tank and determine conveniently when it needs refilling, it being merely necessary to lift the hood. The mouth of the tank 26 is secured by split collars 28 which are fastened by suitable bolts to castings 27. I provide a spindle 29, nut 34 attached to the end of said spindle in any suitable manner as by split pin 35, and a coil spring 32 interposed between the nut 34 and the end of casting 27 as shown in Fig. 6, and operating substantially in the same manner as the coil spring, nut and spindle disclosed in the first form of my invention shown in Figs. 1-5. Spindle 29 is provided with oil passage 36 shaped to aline with oil passage 37 through casting 27 when the tank 26 is in the position shown in Fig. 6. Casting 27 as shown in Fig. 8, is provided with a funnel 39, the small end of which is of suitable size toaline with the opening 36 of spindle 29 when the tank 26 is swung to reverse position shown in dotted lines in Fig. 7, in which position oil may be poured into tank 26. A suitable collar 31 is provided for coil sprin 32 to abut against as shown in Fig. 6. Spindle 29 preferably is provided with a threaded end 33, as shown. Funnel 39 and its opening 38 are cast integral with member 27, as shown in Fig. 8.

Referring to Fig. 10, I provide suitable members 41 and 45, the function of which is equivalent to that of the transmission covering of the automobile. This frame is protank 26 is nprmally held in upri ht position, but may be readily released an reversed to inverted position for purposes of filling. Collar 31 and spindle 29, as shown in Fig. 12, is provided with flanges 49 which set into recesses 50 in casting 27, for stabilizing the container. Collar 31 is provided with longitudinal slots 51 into which a pin 52 projects and in which slots it is slidable. Spindle 29 has a wedge shaped top, as indicated in Fig. 7, against which the sides of the brackets 30 fit, holding the spindle part always in righted position. This edge portion of the spindle is on that part only which fits into the supporting brackets 30, the clamps of which bracket are drawn up tightly and bolted together, as shown in Fig. 6. Spindle 29 is about eight inches long and sets level horizontally. About five inches of this spindle is tapering at the front end, preferably from about one and one-half inches down to about one-half inch at the front end, to which the coil spring 32 is mounted. Cover 31 is provided with a flange that points outward and backward.

The same operation occurs with this form of the invention when filling as in the form first described, in regard to the openings for the passage of oil being thrown into and out of alinement at appropriate times for admitting or preventing the passage of oil to and from the tank. The tank holds about two and one-half quarts preferably. The operation of pipes 13 and 1a is identical with that described in the first part of this specification relating to Figs. 1-5.

hat I claim is:

1. In a device of the class described, the combination of an oil tank having an elliptical mouth, an opposed funnel member, in one of the funnels of which the mouth of the oil tank is mounted, said funnel member or inverted position, means for mounting the aforesaid member, an inner oil pipe in communication with the oil passage in the aforesaid spindle, the oil pipe extending into the lower portion of the crank case of the automobile, and a concentric outer pipe mounted on the first mentioned pipe, said second pipe having its lower end extending substantially below the end of the inner pipe and being in communication with the oil in the crankcase of the automobile and having perforations in its upper end for the admission of air, and means for gaining access to said pipes.

2. In a device of the class described, the combination of an invertible oil tank, a spindle on which the oil tank is pivotally mounted, said spindle having an oil passage in communication with the oil tank, an oil conduit from said oil passage extending into the lower portion of the crankcase of the automobile, and a concentric outer conduit mounted on the first mentioned conduit, said second conduit having its lower end extending substantially below the end of the inner conduit and being in communication with the oil in the crankcase of the automobile and having perforations in its upper end for the admission of air.
