LUBRICATING OIL RECLAIMER Filed March 28; 1942 Patented Apr. 4, 1944 UNiTE D Sra a LUBnIoAriNG on. RECLAIMER Bruce Morris, Calgary, Alberta, Canada.

Application March 28, 1942, Serial No. 436.545 In Canada July 7, 1941 (Cl. B-122.5)

2 Claims.

My invention relates to improvements in lubricating oil reclaimers, an object thereof being to provide a device of the character herewithin described, by the use of which oil may be reclaimed as distinct from being merely filtered, water and gasoline being vaporised off in the reclaiming process. l

A further object of my invention is to provide a device 0f the character herewithin described wherein the vapors are prevented from returning into the filtering chamber, by contrast, being kept separate and discharged into the atmosphere.

A further object of my invention is to provide a device of the character herewith described attachable to the motor of an automobile, being compact so that it may readily fit within the hood thereof to reclaim oil used for lubricating the engine while the motor is running.

A further object of my invention is to provide (in a third embodiment thereof) a reclaimer requiring only one main casting for the filter chamber and vaporising chamber including the vaporising element therein.

in all the embodiments herewithin described and illustrated, a reclaimer which is of eminently simplied construction, simple and economical to manufacture, rugged and long-lasting, which cannot readily become out of order and which is easy to refill with the necessary filtering material.

With the above more important objects in view and such other minor objects as may appear as the specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawing, in which:

'I'he figure shows a sectional elevation of my lubricating oil reclaimer.

In the drawing like characters of reference indicate corresponding parts in the different figures.

Describing rst the embodiment of the accompanying figure, it will be seen that the lubri- 'I are provided, through which oil may seep and overflow into the drip chamber 8 via the annular,` outwardly bevelled flange 9 which precipitates the oil clear of the wall of the inner casing.

An oil inlet IIJ communicates with the base of the inner casing 2, a screen disk II being preferably provided at the base of the inner casing to prevent disintegration of the filtering material.

Within the drip chamber 8 and surrounding the inner casing but spaced therefrom, is an annular heating element I2, through which hot water from the circulating system of an adjacent engine, or exhaust gases, may flow, the same entering the element through the intake I3 and being discharged through the outlet I4. The actual heating area of the element will be seen to take the form of an annularly corrugated, frusto-conical surface I5.

An oil return I6 extends through the base plate I'I of the outer casing I and it will be seen that the same surrounds the oil inlet I0.

Within the cap 3 I provide a central aperture I8 capable of being closed by the valve I9 attached to the cork oat 20 held within the cage 2|.

In operation, it is to be understood that oil to be filtered and reclaimed first enters the inner chamber 2 via the inlet 9 and passes upwardly through the filtering material 5 for this purpose, thereafter discharging through the apertures 1, gravitating over the flange 9 to drip onto the uppermost corrugation of the heating surface I5.

During its passage over the corrugated heating surface I5, water, gasoline and the like with which the oil is diluted, is evaporated oi and when the reclaimed oil reaches the lowermost corrugation, it drips off and falls onto the inverted frusto-conical surface II of the outer casing and returns through the conduit IB for re-use. The gasoline and water evaporated off rises in the form of vapor and discharges through the escape aperture I8.

Since many modifications can be made in the invention herein described and since the accompanying drawing has been prepared only to illustrate the relative arrangement and interaction of parts and not with regard to accuracy of dimensions for manufacturing purposes which in view of this disclosure I consider to entailmerely mechanical skill together with the skill of the mechanical draftsman, and since many apparently widely different embodiments of this invention may be made within the scope of the accompanying claims without departing from the spirit and scope of the same, it is intended that all matter contained in the accompanying speciiication shall be interpreted as illustrative only and not in a limiting sense and I desire only such limitations placed thereon as justice dictates.

What I claim as my invention is:

1. A lubricating oil reclaimer comprising in combination inner and outer casings, said inner casing being spaced from said outer casing to provide an encircling drip chamber, an oil inlet communicating with said inner chamber at the base thereof, iiltering material Within said inner chamber, at least one oil discharge point at the top of said inner chamber, a heating element at' least partially encircling said inner chamber, oil

which has been ltered passing outwardly at said discharge point and dripping onto said heating element and an oil return in said outer casing.

2. A lubricating oil reclaimer comprising in combination an inner casing containing oil filtering material and having an oil inlet at the base thereof and at least one oil discharge point at the top thereof, an outer casing surrounding said inner casing, an oil heating element at least partially encircling said inner casing, said element including a heat radiating surface inclining out- Wardly and downwardly from said inner casing, oil which has been filtered passing outwardly at said discharge point and dripping onto said heat radiating surface, and an oil return in said outer casing.
