- :The' heater-radiator as above described comprising thehead er's Ill and H is mounted in pof sition' within'thecylindrical casing portion M between'the shutters '23 and the offset portion v 20'of;the"casing,-being held in position by any Csuit'able' means; In'the arrangement shown the .niounting mean slcomprises blocks 28 ofyielding material "compressed between the 'front face, of.

the radiator 'andithe' adjacent portion of the casing.

As is best shown in Figs. 2 and 3,Qthe ofiset 'portion'20of-the casing is provided .with a series of :openings 29 therein in spaced relation there'- about. For closing the openings 29, I have pro- 4 vided arotatable damper 30 provided with openings 3|;therein, the arrangement being'such that the-openings .can beturned into position to register'with-the openings 29 or may be turned out'fof registration so as to cause the damper 30 5 to close the openings.

EM. OFFICE An auxiliary housing member 31 is provided the shutters 23.

about the pinions 33 and 34, as is clearly shown in said Figs. 3 and 4.

In the arrangement shown I have provided a spring 38 mountedupon a pin 39 so as to bear against the inner. face of the damper 3B for holding the damper by friction in any adjusted position.

Within the offset portions 20 andll of the casing, I have provided a plurality of fans for fore ing air through the radiator core and out between centrifugal fan member is provided comprising a plurality of vanes iii carried by a sheet metal drum ill closed atone endand mounted fixedly upon the shaft 52 of an by means or a plate M and bolts 45 upon the integral rear wall portion of the casing. extension 2 i. In the arrangement shown, the vanes which a plurality of radially extending fan blades ll are rigidly mounted in such position as to drive air toward the left in Fig. lthrough the adjacent radiator corefupon rotation of the two fans by the motor :33. The'vanes ll! are ,arranged in suchposition as .to be efiective when the fan is rotated for ing the air I I have provided the usual conduit means 48 about the drum l! so arranged that thespace between the drum and the wall of the conduit increases,

in depth radially in counterclockwise direction in Fig. 3. The space between the conduit member 48 and the drum M is closed at the front by plate 19. The arrangement is such that the. air

or it may be connected witha foot warmerfor other special-use device if desired.

As is casing offset portions 2i} and 2| are provided with openings to which a duct-Eit-A is connected, such duct Pit-A preferably to be extendedqin any suitable manner 'thI'OIlgh 'thG wall of the car body, so as to open at one side of thecarfor providingfresh air from the outside in contrast I with the action of the openings 29 which permit air U enter the casing irom the body of the car.

Within the housing ll, 1 have mounted my im-v proved valve mechanism comprising a valve .casing made up of a cylindrical portionil and' a closure plate 52 secured I b-ymeans of screw threads in one end of the cylindrical portion;

the opposite end of which is closed by means of a plate 53 formed integrally with the portion The plate 53 in thearrangementshown is provided with six openings therethrough,, such openings being indicated by the numerals 54 to 59 inclusive asis best shown in. Fig. '7. As is clearly shown in Figs. 5 and,6, theplate 53 is provided with nipples on its rear face communicating with the openings 55 to 59. Nipples 68.

and 6! communicating with the openings 55am! 58 are adapted to be connected with any'suitable source of ice water, being shown in Fig. 5 as In the arrangement shown,-a

40 are formed integrally with the drum M which is pro-L vided at its forward face with a ring 46 upon' 7 driving air outwardly away from the axis of rotation of the fan. For collectdriven outwardly bythe vanes 49,

connected with any suit best shown at the left a Fig.3., the;

being connected with pipes 62 for this purpose.

Nipples 63 and 64 are connected with the oppositely disposed openings 56 and 59.respectively-, such nipples 63 and 64 being connected with opposite end portions of the upperheader IU of the radiator, such header being divided at an intermediate point by means of a plate '65. vNipples 66 and 61 communicate with the oppositely disposed openings 54 and 51 and are connected with pipes 68 leading to the radiator of the car upon which the device is mounted.

For efiecting a suitable connection between the, several openings v 54 to for the desired valve casing, su'ch 'valve member 69 being pro- 59 as may be required operation of the device, I have provided a rotaryvalve member 69 within the electric motor 63 mountediin. itsrear face,v as. is clearly shown in Figs. 6

and'8. The recesses I0 and II are shown in FigwSwtdbe of arcuate form extending circumierentially, the arrangement beingsuch that when the parts arein the position as indicated in Fig. 5 the. Openings 55 with each other, as are the openings 58 and 59 As will'be readilyunderstood, when the valve member. 69 is given a rotary movement through 60 degrees in counterclockwise direction in Fig. 8, the .;conditions will then be changed so as to cause the openings 54 and 59 mm connected and the openings 56 and 51 to be connected. In .the arrangement as shown in' Fig. 5. corresponding tothe position of the valve member. asshown in Fig. 8, the cold water pipes 62 are connected with opposite end portions of the header Hi.

When thevalve member 69 isgiven a rotary movement in counterclockwisedirection in Fig'. 8 as and 56 are in communication aboveisuggested, thev hot water pipes from the radiator-of, the automobile willthen be in header H1. a i

Means is-provided for rotating the valve member 69, comprising a lug 12 on-the mm face of said member extending through a suitable opening in the front plate 52 .of the valve casing; said lug having a suitable handle I3 mountedthereon for the manipulation of said' valve member 69, such handle-l3, being omitted; from the showing of-Fig.6. V 1 q It is believed that it is notnecessary'to describe in detail the operation and effect of the fan means as above described, since' such @parts fornrin and of themselves no part oimy present invention. The motor(l3,.drives ;.the centrifugal'fan comprising the vanes '40 and vvith'it at the'same speed thefan comprising the blades 41. With the openings 29 open, and with'the shutters 23. turned moreor less'from their vertical positions, air is driven straight forward through theradiator and out through the shutter device by the 'fan comprising said blades 41, such air being provided. in part through the openings 29 and in part through the duct-'-A.. At thesarne time the centrifugal fan is forcing air outwardlythrough the duct 50. such air being drawn largely from the leit in Fig. 4 through the radiator, a minor portion of such air being supplied probably through the openings 29 from which itfinds its way past the blades 4'! soas to enter the drum M from theleft in said Fig. 4. The extent of the opening ofthe shutters 23 and of the damper 30 Y a circulation of water is maintained through the radiator as shown in Fig. 5 so as to cause the air passing from the fan through-the radiator either to be heated or to be cooled, depending upon the position of the valve member 69. In case the device is being used for cooling purposes, the connection of the duct with the foot warmer or other special device may be bro' ken if desired, or the connections intact.

By the use of my improved arrangement, I have provided a'construction which is very commay be left pact, which is highly effective in operation, and

which can be very easily and readily controlled for obtaining the desired results.

While I prefer to employ the form of apparatus as shown in' my drawings and as above described, it is to be understood that my invention is not to be limited to such form except so far as the claim may be so limited, since it is evident that changes might well be made in the form and arrangementof the parts whereby equivalent constructions would be provided com ing within the scope of my claim.

I claim:

A three-piece'valve, comprising a flanged plate having three pairs of oppositely disposed ports formed therein, the diameter of each port being less than half the distance between the centers f of any two adjacent ports, two nipples having openings therein and formedintegrally with said plate at the upper portion thereof, each opening connecting with one of said ports, the first oneof. said nipples extending 'rearwardly from said plate and the second of said nipples extending horizontally thereof, a block integrally formed on the lower portion of said plate and having four nipples integrally formed thereon and four s'eparatepassagewaysformed therein, each communicating with one of said ports, two of said nipples extending downwardlyfrom said block and associated with'one pair of said oppositely disposedv ports, one of said nipples extendingrearwa'rdly from said block parallel to said first nipple'and associated with that port opposite to the port associated with said first nipple, and one of said nipples extending horizontally fromsaid block parallel to said second nipple and associated with that port which is opposite to the port associated with the said second nipple, a second flanged plate centrally apertured, the flanges of said first and second plates being screw threaded for cooperation with each other, and a disc positioned between said two flanged plates and having anintegrally formed lug centrally disposed thereon and extending through said aperture in said second plate for controlling the angular position of said disc, said disc substantiallycompletely occupying the space enclosed by said two flanged plates and being provided with two oppositely disposed recesses, each of a lengthand shape to register with not more than'two adjacent ports at any one time.
