' .2 Claims. (Cl. 123-171) The invention relates to cooling means deextend above the oil, as shown at M. O is a signed for use in connection with internal combreather or air outlet which is connected to the bustion engines with the primary purpose of crank case. cooling the lubricating oil and the invention With the construction as thus far described,
consists in the novel construction as hereinafter when the engine has been running for a suihcient 6 set forth. length of time to become thoroughly heated, the
In the drawings: throttle I is opened by suitable means such as Fig. l is a side elevation partly in longitudinal a rod N extending to a point accessible to the section through an internal combustion engine driver. This will permit cold air to enter the to which my improvements are applied; bell mouth G, pass through the filter and by 10 Fig. 2 is a sectional plan view thereof; the throttle valve into the portions J of the Fig. 3 is a cross section; conduit which are immersed in the oil. Also air Fig. 4 is a sectional plan view, and is discharged through the conduits K into the Fig. 5 is a cross section through a modified 'upper portion of the crank case and into the construction. hollow pistons each time they are at the down- 15 I In the operation of internal combustion enward end of the stroke. Also, when the pistons gines it is well understood that the lubricating are at the upper end of the stroke, air disoil if highly heated loses to a considerable extent charged from the conduits K will contact with its lubricating properties. It is usual to hold the a portion of the wall of the cylinder. The air oil supply in the oil pan or sump formed in the discharged from these conduits and also that 20 lower portion of the crank case and consequentdischarged from the restricted end conduit M ly the heat of the crank case is communicated will pass out of the crank case through the thereto. I have therefore devised a system of breather or outlet 0, thereby dissipating a large cooling which is applied not only to the direct portion of the heat which usually is imparted to cooling of the oil but also to the lessening of the the oil. Furthermore, as the temperature in the 25 heat communicated to the crank case from the cylinders and upper portion of the crank case engine cylinders. As illustrated, A is a multiis much higher than 'the temperature of the cylinder internal combustion engine for use on oil, it is obvious that after heat has been exa motor vehicle, B are the individual cylinders tracted from the oil by the air in the conduit J,

The lower portion of the of extracting further heat. Thus I obtain the crank case forms an oil reservoir from which greatest efliciency in cooling the oil by using the the oil is distributed to the parts to be lubricated air first to directly extract heat from the. oil and by any suitable system (not shown). subsequently to extract further heat from the 35 To 0001- the oil and the crank case, I-have desource which would otherwise be communicated vised the following construction: G is anair to the oil. conduit, preferably having a bell shaped mouth For certain uses it may not be necessary to G so located as to receive a blast of cool air have this double cooling efiect, but only to exdue to the forward movement of the vehicle. tract the heat directly from the oil.

The conduit G enters the to and under the control of the driver. The
crank case D through one end thereof near the conduit P enters the crank case through the end 45 bottom and extends longitudinally through the wall thereof and then connected to a transverse case as indicated atJ in a position where it will header R which in turn is connected to a series be immersed in the oil. Connected with this of conduits S passing longitudinally through the portion J at various points are conduits K of oil pan, being connected at their rear ends with a smaller dimension which extend vertically upheader T while the latter is connected to a con- 50 ward in the crank case and to a point which duit U passing through the rear wall of the crank will be within the hollow piston C when the case. With this construction the air which is adlatter is at the lower end of its stroke. The end mitted through the conduit P is distributed of the portion J of the conduit is contracted as through all of the conduits S which being im-- indicated at L and is then turned upward to mersed in the oil, will extract the heat directly 55 therefrom.
