To all whom it may concern: y

Be it known that 1, JOHNW.` STIEFEL., a citizen `of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certainnew and useful lmprovements in Radiators `for Autospecilication. y

My invention relates to improvements in radiators for automobiles oi" the'water circulating type, its object `beingto dispense with the water-tubes forming part of the ordinary radiator, and to otherwise cheapen and simplify the construction and make the same more effective. y y

' More particularly the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed. y v

lin the accompanying drawings showing one embodiment of the invention,

Figure 1 is a perspective view of my im-` proved radiator shown partly broken away.

Fig. *2 is a vertical section through the bottom portion of the radiator, showing it in inclined position assumed when the car is moving up an inclination, and

Fig. `3 is a detail view ot the top partei? one of .the screens Aand -an adjacent wall forming part of the radiator.

Referring to the accompanying drawings,

A represents the side walls ofmyimproved radiator, the lower ends 2 of said walls being bent outwardly/pand secured as by rivets 3 to the automobile chassis 4:. The front edges oit' the side walls are connected by` a plurality of plates 5 spaced` apart and directed downwardly relative to the radiator. The rear edges of the side walls A :are similarly connected by a plurality ot plates @spaced apart and directed upwardlyrelative tothe radiator. Constituting the bottom of the radiator is a tankportion 7 connected by a tube 8 with the waterl circulating system. rlFhe radiator bottom 7 is formed with an oblique division wall 9` connecting y the front and back oi' said bottom and being directed downwardly toward the rear. A Wall 10 extends upwardly :tromthefgtront end of the wall 9 to the top ot the back wall of the radiator bottom. The walls 9 and 10 are formed with perforations 11 and 12 respectively for the purpose hereinafter pointed out. rlhe front wall of the radiator bottom extends upwardly beyond the adjacent ends. of the division walls as shown best in Fig. 2. f.

A `plurality of vertically disposed openn work partitions 13 are supported upon the wall 10. rl`he partitions 13 are spaced, apart as shown in Fig. 1 and extend upwardly` between the plates and 6 to the under side of the hollow radiator top 14. The bottom wall 15 oit the radiator top is formed with openings 16 directly above theupper ends of the partitions 13. The upper ends 17 ot the partitions 13 are preferably doubled upon themselves underneath the openings 16. rllhe tubes 8 and 18 form opposite connections for the radiator with the water dis-` tributing system. rlhe radiator top is 'formed with the usual filling inlet tube 19 to per-` mit lling of the radiator. y ln` lilling :for use the water .is poured through the inlet tube to supply the radiator in the ordinary way. The` waterwhen it -is not @being circulated stands atthe bottom of the radiator below the open work or screen partitions and also below the wall9 or approximately on the level with holes 11 as shown in Fig. 2. When. water is beinglcirculated as by the water pump ordinarily used it will pass from the tube 18 to the radiator top, thence passing through the openings 15 onto the screen partitions. The water `will thence travel down the partitions and pass through openings` 12 in theplate 10 onto the plate` 9, `and willthen pass through opening 1l to the space below `said plate 9. As the C2141t carrying the: radiator moves rapidlyforu ward through space,the inertia in the water as it flows upon the plate 10 is not fully overcome,` therebycausing a large portion of it to flow rearwardly. For the purpose of arresting a too rapid rearward `flow of the water.` and thereby avoid: splashing `ag'gainst `the rear `wall of the ltankportion 7.,

spread film-like over the plate 10, thereby delaying its descent and iiow through the lower of the holes 12, thereby further cooling it. The upper holes 12 near the rear wall, catch any water that may find its way to that uppermost portion of the plate 10, when the car is exceeding a normal rate of speed. The function of the lower plate 9 is identical with that of plate l0, except that it is operative in abrupt stops and backward driving of the-car. The turned or thickened upper ends 17 of the partitions assist in guiding the water as it passes from the openings 16 onto the body of the partitions. By having the walls 9 and 10 inclined as above explained, the water from the partitions runs more freely into the hollow radiator bottom, and also the main body of water is forced back and forth through the holes l1 in said wall 9 by the motion of the car.

The plates 5 being directed downwardly from the open front' of the radiator to form deflector plates prevent water, etc., being blown into the interior of the radiator. The plates 6 being directed upwardly at the open back of the radiator tend to direct any water that may be blown against them from thescreen partitions back into the interior of the'radiator, conserving the supply of water.

' The spaced walls 5 and 6, while having the advantages above noted, at the same time allow the circulation of air through the radiator to assist in the cooling action of the water.

By my improved construction I avoid the objections ofthe ordinary tubular construction of radiator securing a construction which is particularly 'easy to keep` from leaking' and very cheap and simple. My construction is particularly adaptedv for winter use as there is not the danger of freezing that there isin the ordinary tubular construction. In Fig. 2 the radiator is shown tiltedto a position with the car on an inchne, showing how the water stays almost wholly vbelow the top vwall l0, the water having'access to the space between the plates 9 and IO, solely through the holes 11, which are at the lowermost edge of the plate l9. The car will travel overv short steep grades, before the comparativelylarge` bodyof water will have had .time to flow throughv the holes 11, thereby controlling the waterv in the tank'to prevent obstruction ofthe spaces above wherein the cooled water is descending. v I claim radiatorA of.` the class described' comprising side walls connected. across the front and baclrby spaced inclined dee'ctor plates, saiddeflector plates 5 being inclined downwardly and'plates 6 upwardly relative to the radiator and outwardly from said front and back, a hollow radiator top supported by said side walls, a hollow radiator bottom and a plurality of open-work vertically disposed partitions supported in spaced relationship above said bottom, and extending upwardly to said radiator top.
