PATENT OFFICE This invention appertains to new and useful improvements in appliances for internal combustion engines and more particularly to a novel oil cooler. I
The principal object of the present invention is to provide a coolerfor use in conjunction with internal combustionengines whereby oil of the crank case can be treated to maintain the same at a relatively low temperature.
Other important objects and advantages of the invention will become apparent to the reader of the following specification.
In the drawings:
Figure 1 is a side elevational view of the device applied to an internal combustion engine.
Figure 2 is a top plan view of the cooler attached to the engine.
Figure 3 is an enlarged fragmentary detailed sectional view taken substantially on line 3-3 of Figure 1.
Figure 4 is a cross sectional view taken substantially on line 44 of Figure 2.
Figure 5 is an end elevational view looking in the front end of the device.
Figure 6 is a sectional view taken substantially on line 6-6 of Figure 3; I v 7 Referring to the drawings wherein like numerals designate like parts, it can be seen that the numeral 5 generally refers to the internal combustion engine which isequipp'ed with the usual crank case 6 and cooling fan I, the fan I being preferably provided with an auxiliary pulley 8 used in conjunction with the present invention.
The cooler which is generally referred to by numeral 9 consists of the cylindrical shell I provided with a header II inthe forward end of the shell I0 and a second header at the opposite end of the shell. A plurality of tubes I3 extend through these headersand open to the atmosphere so that air can pass therethrough for cooling the oil contents of the shell.
A shaft I4 is journaled through the headers and on its forward end is provided with a pulley I which is connected to the auxiliary pulley 8 on the fan shaft by a belt I6, while inwardly of this pulley I5 isan impeller fan I1. for driving air through the tubes I3. 7
An outlet conduit I8 extends from the bottom of the shell I0 and connects the crank case 6. At the rear of the shell I0 is a pump for sucking the oil from the crankcase and delivering the same to the shell I0 and this consists of the cylindrical housing I9 into which the rear end I of the shaft I4- extends through a packing gland 20. On the rear end of the shaft I4 and within the housing I9 is the rotor 2| which snugly engages the inner side of the housing. The rotor 2| 6 is connected to the shaft I4 by a relatively thin web 22 having a pair of openings 23 and 24 therein; A plate 25 is secured against the rear side of the rotor in spaced relation with the web 7 22 and this is provided with a pair of struck-out portions 26, the tongues being formed by the struck-out portions being turned upwardly obliquely with respect to the plate 25.
An inlet pipe 21 extends from the crank case 6 and communicates with the rear end of the housing I9. The forward end or header 28 of the housing I9 has a pair of pipes 3Ii-3I) extending therefrom and these communicate with the rear endportion of the shell I0. 9
I It can now be seen that with the shell I II properly supported by the straps 3 I--3l which in turn are suitably secured to the connecting flanges 32 between the engine crank case and engine base, the entire apparatus will be in a position for use. With the pulley 8 driving the pulley I5, the shaft I4 will ,be rotating and in operating the fan I! will drive fresh air through the tubes I3 so as to maintain the oil passing through the shell I0 7 normally cool; This oil is obtained by the action of the pumpblades 26 on the fluid, whichtcause the fluid to pass from the pipe 21 through the rotor 2| by way of the pipes 30, to the shell III. i While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and 35 materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
What is claimedis:
Incombination with a crank case, a shell h'av- 40" j 7 NELL E. CAMMACK.
