E. W lS'chioerla By/Wm Attorney Patented June 3, 1930 ED'VVIN W. SCHLOERB, OF SAN DIEGO, CALIFORNIA LUBRICANT HEAT-DZSSIPATING MEANS Application filed March 13, 1929. Serial No. 346,?33.
The present invention appertains to a new and useful improvement in internal combustion engines and more particularly to a novel crank case, provided with means for dissipating heat in the lubricant.
The paramount object of this invention is to provide a heat dissipating crank case for automobiles, which may be applied to the usual internal combustion engine without altering its present construction.
Another important object of the inven tion is to provide air cooling means for the lubricant of an automobile, whereby considerable lubricant will be conserved, espe- 5 cially during long trips when oil is lost in vaporization due to the constant heat of the engine.
These and other important objects of the invention will become more apparent to the reader after considering the invention as described and claimed hereinafter.
In the drawings:
Figure 1 represents a side elevation of the improved structure attached to an engine.
Figure 2 is a top plan view of the improved structure.
Figure 3 is a fragmentary vertical sectional view through the structure.
Figure 4 is a fragmentary vertical sectional view showing the present invention secured to an engine.
Figure 5 is a fragmentary vertical sectional view of the device.
Figure 6 is a diagrammatic view showing a modified form of the invention.
Referring to the drawings wherein like numerals designate like parts, the usual engine block A is provided with the flange B to which the usual oil pan is ordinarily attached.
In lieu of the oil pan, the present invention is employed and this is generally referred to by numeral 3.
The invention consists of a trough 4,
having a pair of flanges 55 extending around its perimeter. The uppermost flange is adapted to engage the flange B of the engine block.
A pan 6 is provided with a flange 7 at its perimeter. The pan 6 has a cover or top wall 8 and between the top wall 8 and the bottom wall of the trough 4 is connected a plurality of cooling tubes 9, each provided with a plurality of spaced and 'circumferentially extending rings 10. A level gage 11 is also interposed between the wall A. and the bottom of the trough 4,. in the manner shown in Figures 1 and 4, respectively. The bottom of the pan 6 declines toward the drain outlet 1 A relatively large tube 13 connects the trough 4 with the pan 6 and through this tube is disposed a pump line 14, which has its terminus at its lower end adjacent the bottom of the pan 6. Through the means of this pump line, the lubricant is displaced from the pan 6, into the trough 4, that is to say, the cool lubricant is taken from the pan 6, and discharged into the trough 4, thus displacing the hot lubricant from the trough 4, which flows through the cooling tube 9 and becomes cool as it passes into the pan. 6. Disposed through openings in the flanges 55 and the flange 7 are bolts 15, which are threadedly engaged within threaded openings in the flange B of the engine block. Arranged on the bolts 15 are spacers 16 for interposition between the lowermost flange 5 of the trough 4 and the flange 7 of the pan 6, obviously to maintain the flanges from buckling due to the stress of the bolts 15.
In Figure 6, the diagrammatic view represents a somewhat modified form of the invention, in that an elongated wall 17 of hollow construction is interposed between the pan 6 and the trough 4 for communicating the interiors of said pan and trough.
Disposed outwardly from opposite sides of the wall 17 are obliquely disposed tubes 18 of relatively elongated cross section. It will be seen that air entering through the radiator and driven by the pan will pass between the wall 17 and the adjacent tubes 18, some of the currents being deflected by the tubes 18 and attracted by the suction of the current passing at the outside of the structure which affords a suction to the current passing through said tubes and along the sides of the wall 17.
A relatively large cooling surface is provided whereby the lubricant can be always maintained cool even during extensive trips of the automobile.
t is also to be understood that while the drawings do not show shutters or any means for excluding air from between the tubes such devices may be employed and maintained closed during cold weather, so that the natural heat of the engine may be utilized for maintaining the lubricant heated to the proper degree.
Changes in the specific shape, size and materials may be resorted to, when manufacturing this attachment without departing from the spirit and scope of the invention as claimed hereinafter.
It is to be understood that by housing in the tubes of the oil cooler the device can be used on stationary and marine motors by having a stream of water flowing through the housing. This would be of great advantage on fire apparatus.
Having described the invention, what is claimed as new is:
A heat dissipating device for motors comprising a trough for attachment to a motor, in place of the usual oil pan, a pan, a plurality of tubular connections between said pans and the trough through which the oil from the trough may flow, said tubes each being of elongated cross section, and an elongated hollow wall mounted between said trough and pan, said tubes being disposed vertically between the trough and pan and in a forwardly diverged relation with respect to the partition.
In testimony whereof I afiix my signature.
