MEANS FOR DISCHAEGING FLUID FROM INTERNAL-COMBUSTION MOTORS.

Application filed July 7,

The present invention relates to motor vehicles of the type driven by an internal combustion engine. In such engines, although it is well known that the crank case must be cleaned out and the lubricating oil must be changed often in order to prolong the life of the motor, it is also well known that the average motorist, due to the necessity of getting under the car in order to open the discharge valve, will delay the changing operation beyond all reasonable limits. This the present invention avoids by providing readily accessible means whereby the user may release the oil after merely lifting the hood or corresponding cover, in the case of an automobile or motor boat, or, in any event, without the operator being required to get or reach down under the crank case. -This general purpose may be accomplished in various ways, but I prefer to construct the valve operating means in such manner as to be supported or guided by the flange of the crank case, or by a guiding element secured thereto, as will be more fully understood later.

Another purpose of the invention is to provide, in connection with the oil releasing means, a gauge and a filler conduit whereby the user may refill the crank case and constantly observe the height of the oil as it rises therein, and whereby he may note Iwhen it is discharged. In some instances the gauge may, of course, be omitted.

Further objects will appear upon refer-- ence to the description and to the drawings in which Fig. 1 is a perspective View, arts being broken' away, showing one em odiment of the invention. -Fig. 2 is a front View, parts being broken away rearwardly of the front support, which is not shown.

Fig. 2 shows a slight modification in the rod guiding means. Fig. 3 is .a vertical section on line 3.3 of Fig. 2. Fig. 4 is a perspective View, parts being broken away, showing a'second embodiment of the invention, wherein the discharge valve iscombined with a filling conduit. Fig. 5 is a fragmentary side elevation and Fig. 6 is a vertical section, showing more clearly the details of the construction which appears in Fig. 4. Figs. 7 and 8 are views, similar to Fig. 6, showing a further slight modification. Fig. 9 is a side elevation of Fig. 7, showing flange 1 in cross-section on line 9-9 of Fig. 7. Fig. 10 is a view similar to Fig. 2, showing still another embodiment 1922. Serial No. 573,459.

of the invention. Figs. 11 and 12 are fragmentary sectional views showing slight modifications. v

Referring to Fig. 1, 1 indicates the internal combustion engine, 2 the radiator and- 3 the hood of an ordinary motor vehicle,

the cylinder block including, as shown m Fig. 2, the flange 4:, by which the weight is carried to suitable supports (not shown)' at the rear. The usual detachable oil panappears at 5 and the space between the side frames 6 and the crankcase is closed by suitable metal sheets or plates 7 It will be observed (Fig. 1) "that the oil pan includes.

a gauge 8, which may either be welded, or otherwise attached to the pan, and by which the 'level of the oil therein may be seen. The oil pan also includes in its bottom an opening 9, Fig. 3, which may be formed either in the pan itself or-in a separate fitting 5' (Fig. 2) bolted thereto, and which is threaded to receive a suitable valve element embodying a housing 10 and a rotatable valve 11, having

complementary passages

12 and 13 as will be readily understood. The valve also preferably embodies sealing means such as the gaskets or packing 1 1-15 and may beheld to its seat bya spring 16; and its operating handle, which Forthe purpose of readily actuating said .valve when the hood is elevated, I provide socket 23, one of which is suitably secured to the arm as by nuts 24. spring interposed between a pin 26 on the rod and the flange 4 serves to normally hold the valve in closed position. By removing the pin 26, the rod 20 may be disconnected from the handle I 17 or from the sleeve of the ball 22byunscrewing said rod by which it may be drawn up and removed through the opening in the rib or flange .4, as shown in Figs. 1, 2 and 2 In the construction shown in Fig. 10, the upper end of the rod respectively in the plate 7 and ina clip 29 which is secured to the side bar by one of the same bolts 30 which serve for the attachment of the plate 7. In similar manas appears at 17, is preferably perforated as ice 20 is guided in openings 27 and-28 formed.

her, the opening 21 may be'superceded by a perforated clip 31 attached to the flange.

' structions shown 4, y one or more of the bolts 32, as shown in Fig. 2.

In the modification shown in Figs. 7, 8 and 9, the rotatable valve is replaced by a slidablevalve 11, and for-operating means a bell crank device 35, pivoted at 36, and rod 20 are provided, the spring 25 in this, instancebeing positioned between the upper surfaceof the flan e 4 and 'an operating knob on the rod. T e valve housing is also shown integral with the gauge fitting 8" and attached to the oil pan 5 by bolts 37. This construction requires a minimum road clearance.

Substantially the. same end is accomplished in Figs. 11 and 12 by the use'of a rotatable valve 40 and

discharge passages

41, 42, 43 so arranged that the valve need be turned through but a small arfglefrom closed to open position. The operating rod therein shown is substantially the same as that shown in Fig. 1.

In order that the user may also readily pour in the fresh oil and constantly observe its level during the filling operation, I also provide in some instances a combined filling and discharging device and gauge, as shown in'Figs. 4, 5 and 6, the same being secured to the main oil pan 50 by bolts 51 (although it might be integral therewith). This device includes a chamber for suitable gauge mechanism 52 and likewise has a combined filling and discharge passage 53, registering with a corresponding passage 53 formed in the pan 50, from-whlch the usedoil-is drawn ofl' t -rough a branch 54 when the valve 55, which may be of any suitable construction, such as those heretofore described, is opened. The passage 53 also has a branch 56 which is prefera ly provided with a butterfly or other suitable valve 57 the operating handle of whichis interconnected to the discharge valve operating rod 58 in such manner that the valve 57 is open only when the discharge valve is closed, for example, by the pin and' slot connection 59'60, the purpose being to prevent refilling until the discharge valve s closed. The upper end of the branch 56 1s normally closed as by means of a thin netal plate 61 pivoted at .62, and a spring It will be noted that in each of the conthe operating rod is readily accessible upon merely lifting the hood, and that the spring 25 tends to automatically Te- 1 turn the valve to closed position and. to'

thereafter hold .it in such position so that this valve will not be left open by an absent minded operator who has cleaned out his crank case and is refilling; also that in such embodiments as appear in Fig. 3'the'devic'e1 is readily applicable as an accessory, and that the expense involved is small.
