It is often considered desirable to incorporate a lter in the filling system for the oil sump or reservoir of an internal combustion engine; but the oil may be viscous and cold and it is diiiicult to get it through eicient filtering means within a reasonable time under ordinary pressure.
The main idea underlying the present invention is to provide a large area for the filtering screen with a container above it of sufficient capacity to hold the normal filling charge.
As applied to an internal combustion engine, the container may be placed in a position where its contents will be heated by the engine, and in this way the oil becomes warmed and gradually passes through the filter and into the lubrication system as the engine is running.v
The invention is illustrated in typical form by the accompanying drawings, the parts of the invention for which a monopoly is desired being those delimited by the claims.
In the drawings- Fig. 1 is a side view showing the general a1'- rangement of a preferred form of the invention as applied to an engine with overhead valve gear.
Fig. 2 shows an alternative arrangement as applied to an engine with crank-case oil filling.
Fig. 3 is a sectional elevation to a larger scale of the ller portion of Fig. 1, and
Fig. 4 is a central cross section of Fig. 3.
In the form of the invention as applied to engines with overhead valve gear (Fig. 1 the casing l, la is placed over the valve gear and may form the sole cover therefor or may do so in conjunction with the normal cover 2, discharging into a lling aperture 3 provided therein. The container I has an elongated dome-like cover la and is provided with a deeply crimped or pleated fabric and wire gauze filtering screen 4 suitably supported over the valve gear enclosed by the normal cover 2. The support may be afforded as shown in Figs. 3 and 4 by cross bars of an inner framing 5 and a coarse wire gauze 6. Supporting brackets 1 are secured under the container l and are bolted to the normal valve mechanism cover 2 by the same studs 8 and nuts 9 that secure the cover 2. A ller hole and cap I0 may be provided at the top or slightly to one side of the cover la as may be most convenient. The capacity of the container l over the filter 4 is suflicient to take the normal re-ll of lubricating oil-possiblyv from a pint upwards for ordinary car engines. The desired quantity is then simply poured in over the filter and the cap I0 replaced. As the oil warms up it will pass through the filter and find 2 its way into the return flow from the valve gear to the sump or reservoir. v
In the form shown at Fig. 2 the arrangemen is generally similar to Figs. 3 and 4, but the container i is secured in a suitable position against the back of the dash of a car and a iiexible pipe Il from the lowest point of the container l is suitably secured to the ordinary crank case oil filler cap I2.
While described with more particular reference to internal combustion engines, like purposes to which the invention is applicable would include other cases where oil is carried in a service tank or reservoir (as on aircraft, gun turrets and many other instances) 'from which oil is drawn and to which it is returned and the tank is topped up from time to time by a filling charge.
We claim:
1. A lubricating means for supplying oil to an engine to build up the volume of engine-carried oil to a desired quantity, including a container to receive a build-up oil charge, means for connecting the container to the engine to cause the heat/ developed in the engine to heat the charge in the container, a communication between the container and engine for oil passage, and a lter in the container of a character to prevent filter passage of the conventional viscous oil delivered and afford such lter-passage following the heating of the oil in the container.
2. A means for delivering a build-up charge of oil to the oil body of an engine, said means comprising a container to which the build-up charge is delivered in normal condition, a discharge pas sage for delivering oil from the container to the engine, the container being connected to the engine to utilize the heat of the engine to materially increase the interior temperature of the interior of the container to reduce the viscosity of the oil originally delivered to the container, and a iilter between the discharge passage and main body of the container serving to prevent oil passage to the discharge passage in its normal viscous condition and aord such passage together with the ltering function following sucient heat from the engine, properly reducing such viscosity.
3. A construction as defined in claim 1, wherein a frame is fitted within the container to receive and support the lter, and means forming part of the engine assembly for removably engaging said rame.
