The presentinvent-ion relates: to improvements in an oil catcher and discharger for a'vehicle; and'itconsists:

of the combinations, constructions and arrangement of parts, as hereinafter described and claimed." It has par ticular reference to improvements over the oil-catching receptacle with speed-controlled oil-discharger attachmen-t for automobiles, as shown in my copending application Serial No. 584,016, filed in the United States Patent-Office on May l95 6 now- Patent-No; 2,841,- 245, dated July 1, 1-95 8') In the -above-identified copending application, 1' dis-- close a; receptacle that is ad-aptedto be attached to the clutch pan of an automobile to catch, dripping -ofi oil; This oil a is retained in the receptacle until i the automobile has attained a predetermined speed at which time the accumulated oil is discharged onto the roadwaya. As

illustrated therein, the receptacle defines a wind-tunnel passagewaythrough which air will flow, as the automobile is advanced, with the air picking up the oil for discharge upon the-roadway.

Although the device shown-in the above-mentioned copending application is admirably adapted for use in the average climate, it has been found frompracticethat when his used in cold climates, snow and moistureeentening the wind-tunnel will freeze therein. This will pre vent the discharge ofthe oil ontothe roadway.

Accordingly, and as the principal 1 object of the present invention, it is proposed to provide arr-all weather-oil catcher and discharger fora vehicle. Briefly =stated, 'itis: proposed to utilize a swingahly mounted recept-acle having a-sump therein, positioned to receive .oil draining from the housing of a component of a vehicle powerplant. This receptaclesis swingableintoa'posi'tionto discharge accumulated oil there'from (smo the -roadway; In order'that thereceptacle willibe moved into-oil dis'- charging posit-ion, it is providedwith a portion against which wind wilh strike with sullicient' 'foree' when the vehicle :has attained a 1 predetermined --speed, to swingthe receptacle into a position to automatically discharge the accumulated oil, Until this speed has been attained, the receptacle is'retained ina'positiomto hold' the oil.

While I have shown only the preferred form of my invention, it should be understood that various changes, or modifications, may be made within the scope of the; annexed'claims without departing fromthe spirit-thereof,

Detailed description Referring to the drawing, it will be noted that Ihave discloseda-conventionalclutch pan A, wh-ichis fashioned with an outlet opening 10 in its lower wall 11. It is Well known that a small quantity ofoil' B will accumulate in the bottom Qfthepan- Althoughthe op eni ng,= 10 is normally closed b.y-a plug 12,.some ofthe oil may leak; out and will droponto the garage floor, or upon the: street when the automobile is parked. While I havespe cifically mentioned a clutch pan, it. will be apparent that thesame-@situationmay apply to the housing of agcom ponent of avehicles ower. p ant.

My oil catcher and discharger is designated. generally-- at C in the-drawing, It includes a supporting frame whichmay be secured beneath the pan or housing; A byany suitable means soas,tosurroundthev opening 10., For this purpose, I have shown a plurality of permanent magnets, 1-4. which are accommodated in. grooves Iii fashioned in the upper surface; of the supporting frame D: and-fixed to, the latter; V

I tend to depress forwafd po io sn 0f ll flfifihts l For a better understanding of my invention, reference After the vehicle has attained a predetermined speed, the wind 23 will strike the forward portion 22 of the receptacle with suflicient force to swing the receptacle E into the dot-dash line position shown in Figure 1. At this time, the accumulated oil B will be discharged over the trailing end 25 of the receptacle onto the roadway. The swinging movement of the trailing end of the receptacle from its full-line position into its dot-dash line position is indicated by the arrow 26 in Figure 1.

It will be noted that the drain chute D is disposed to constitute a limit stop, when the receptacle is swung in one direction about the trunnions 16 into an oil-retaining position. The supporting frame D has a section 27 that is disposed to constitute a limit stop, when the receptacle E is swung in the opposite direction, that is, into an oil-discharging position.

The forward part of the supporting frame D is provided with a baffie 28, which extends transversely across the frame D, and this baffie is arranged to substantially preclude the wind 23 from gaining access to the sump E of the receptacle. The forward portion 22 of the receptacle E defines a lip 29, which substantially contacts with the batfie 28 as the receptacle swings up and down.

Summary of operation Assuming that the oil catcher and discharger C has been installed beneath the clutch pan A in the manner shown in Figure 1, the operations thereof may be briefly summarized as follows:

When the vehicle is parked or standing in a garage, any of the oil B in the bottom of this pan that may drip through the opening will be directed by the drain chute D into the sump E of the swingably mounted receptacle E. This accumulated oil is designated at B. The weight of the accumulated oil B and the counterweight 24 will hold the receptacle E in the full-line position illustrated in Figure 1. Thus the accumulated oil B will be prevented from draining onto the floor of the garage or onto the street.

However, as soon as the vehicle has attained a predetermined speed, the wind 23 striking the exposed forward portion 22 of the receptacle E will operate to lift the forward part of the receptacle and thus swing the receptacle into the dot-dash line position shown in Figure 1. At this time, the accumulated oil B will be discharged over the trailing end 25 of the receptacle onto the roadway. Of course, when the vehicle slows down or is parked again, the receptacle E will automatically re turn to its oil-retaining position.

The lip 29 of the forward portion 22 of the receptacle E is protected by the bafiie 28, when the force of the air has swung the receptacle into a position for draining the oil therefrom. This prevents ice, snow, water or mud from being scooped up by the receptacle, while the vehicle moves over the road. It is impossible, therefore, for the receptacle E to become clogged with foreign matter.
