This invention relates to heat exchangers fr reference toa device especially designedfor increased r reduced in accordance" with the cooling lubricating oils.

The primary object of the inventionl isto provide a cooling device orsrhejatezcchanger of the above type which is made up of a series of plates whose size and/or number may be desired installation and which embody fetures of construction which render the device unusually efficient in operation. n

With the "foregoing object in view., the plates of the device are of simple construction .and interchangeable, and providedwith y meanswhi'ch, among other advantages, permit` convenientdrainage and cleaning of the devicewhile in assembled condition, reduce the pressure in the device by eliminating congestion of fluids circulating therethrough, servey to direct the course of the'cooling Huid in its tortuous path, equalize the head pressure of the cooling Huid, and alsoeliminates.

the necessity for by-pass connections for. any excess cooling iuid that may Abevpresent in the cycle.im A' 4 i A rFhe various features of novelty and advantage resident in my improved heat exchanger will become more apparent in View of the following descriptive matter taken in conjunction with the drawings, wherein :---v

Figure 1 is a top plan viewofmy improved y heat exchanger, certain parts belng shown 1n Y may be termed a combined drain and pressure section. y

Figure 5 is a similarview taken substantially on the line 5-5 of Figure 2.

Figure 6 is a plan viewl of one of the head or end plates. l n, i.y C s Figure 7 is a similar viewof the other of the end or head plates.`

According to the present invention, the device comprises a plurality` oi."V l intermediate units or plates, each being identicalpin conv struction vwand theregore interchangeable together with a pair o end heads or plates both of which areidentical in construction and :ro HOMEB. E.

is provided on the side 7 of the plate an arcuate boss orrib 11 provided with an arcuate slot `or port 12.y (See Figure 4.) Between one of the said Aadjacent lugs 9 and a next adi' jacent lug 9 there is formed in the plate an arcuate slot or port 13. On the opposite side ofthe plate, thatis, on-the side 8 and opposite the slot 13 there is provided between two ad-f" jacent lugs 10 and integral with said lugs l() an arcuate rboss orv rib-14. i

The boss 14 is disposed at, what, for the sake of convenience may be termed the top part of the plate while the' boss 11 is disposed at one side of the plate. i

0n theside 8 of the plate diametrcall opposite the boss 14, a lug 15 is provided having an orice 16 formed therethrough and opening on opposite sides ofthe plate. This orifice 16 has a number of advantageous functions, as will hereinafter appear, and

drop or luy-pass orice.

In assembling the plates, the plates have corresponding faces disposed in opposed relation formingalternate shallow and deep chambers I17 and 18 respectively, while to -put the chambers in alternate communication so that the shallow chambers communicate one with another, vand the deep chambers do likewise, each plate is set a half of avice in an alternate manner. Theyportsvliz communicate the chambers 18 at the top and bottom an` alternate manner. {Asfisf also i manifest, the oriices 16 communicate the chambers 18 at the top and bottoml of the de'- vice in an alternate manner. s t' From the foregoing, it will be seen, that the 'oil kor other Huid to be cooled entering thel irst chamber 17 through portsf12 on one side of the device will flow across'the chamber 17 to pass through registering' ports 12-12 on an opposite side owthe device to enter the next chamber 17. t

Y The water, or other cooling mediumenter- I ing the first chamber 18, flowing through Athe first pair of registering ports l3--13,.Will

' End plates 19`are provided and have.

formed integrally therewith an inwardly directed peripheral iiange 20. 0n their inner faces, the end platesV` 19 are each provided with lugs 21 radiating inwardly and arranged in 'circumferentialspaced relation. These lugs are suitably apertured for registry with the apertured lugs on the intermediate plates 5. The several intermediate plates 5 f and said end plates 19 are secured together by rods 22y passing throughfthelugs 9,'10 and .21. Nuts 23 are threaded on the ends of the rods 22.

v Between two adjacent flugs 21 there is formed integrally therewith and with the plate 19 an arcuate boss 24 havin an arcuate recess `or port 25.formed thereln. Com- 'the apparatus is put.

municating with the recess 25 is an oil orifice 26. The end plate, ,within the confine'sof .A l

in the system or cycle' above that required for its rim 20 -in transverse alignmentwith the oil orifice 26 is provided with a relatively large water port or openingI 27. u In practice, then.. it will be seen that oil entering through the orifice 26 of oneend plate will flow through thechambers 17 to discharge from the device thru a the opposite e'nd` of the device. Likewise water will enter the first chamber 18 through the water port 27 infone end plate and iow. in alternate directions through the chamber u 18 to discharge from the device through the water orifice 27 in the end end ofthe device. 1 Y

Each of the end plates on 'a corresponding xside thereof is provided with suitable,y atplate at the ether .taching brackets 29 whereby the apparatus may be secured t'o an engine or toyany suitable support'dependent upon the use to which On each face 7 and 8the plates are provided with studs or projections 30 and 3-1,

respectively, while on their inner faces the' end plates 19l are" likewisef providedl with studs or projections 32, to prevent buckling of the plates and to .further enable theplates Vto rwithstand. a high degree of pressure.

like orifice 26 on the end plate 19 at "be subtracted from or added to at will.

release At the top and bottom thereof, the end plates 19 are provided with suitable orifices 33, to align with the orilices16 at the top and bottom of the device, the said drain orifices 33 being normally closed through the medium of suitable plugs 3d.

It is thought that Vfrom the foregoing description, taken in connection with the accompanying drawings,- themany advantages of my improved apparatus will be readily appreciated by those skilled in the art, as

well as the details of construction yand the fact that the apparatus is adaptable to be used for -a varietyof purposes.

Simply by removing theplugs 34, the water or yother cooling fluid may be drained from all of the chambers 18 Whenfdesired, and

this may be done whether the device be disposed in a horizontal or vertical position or at an angle thereto. :These aligned orifices 16 also serve to guide the Huid on into the next compartment and increase theforce of flow While at the same time decreasing the pressure tin the exchanger by eliminating congestion of fluids atathe points Where the latterreverses direction of'. flow. Furtherincre, any heavy-sediment or other mattertroduced through the holes 33, 16, to further clean the passages Without removing any connection or piping or otherwise disturbing the installation. s

` Another advantage of this aligned orificeand port construction is that any excess fluid and which soon become'apparent with actual use of an exchanger builtin accordance with my inventlon,

construction 'and interchangeable and may The device' may be easily assembled andA taken vapart and the plates are well braced by the llO Thel plates of they exchanger are simple in particular arrangement of studs or projections 30, 31 and32.,

` Even though I have herein shown and described the preferred embodiment of my in- `vention, it is to be understood that the same -.-is susceptible to changes fully comprehended by the spirit of the invention 'as hereinY described, and the scope of the appended claims. f
