AUTOMOBILE-RADIATOR.

Specification of Letters Patent.

Application filed February 12, 1917. Serial No. 147,985.

To all whom it'mag concern:

Be it known that I, JosErn 0. Continue, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Automobile- Radiators, of which the following is a specification.

My invention relates to an improvement in automobile radiators, and the invention consists in a radiator having transverse tubes and a deflector adjacent the ends thereof to cause a circuitous travel of the water through said tubes with the maximum efficiency in cooling results. This deflector is also adjustably related to the tubes to vary the volume of flow of water through a particular section of the radiator so that variable cooling eflects may be obtained to meet climatic changes, for example, summer and winter temperatures.

In the accompanying drawing, Figure 1 is a front view of a radiator embodying my improvement, portions being broken away to show the interior construction. Fig. 2 is a vertical section, front to rear, of the radiator. Fig. 3 is an enlarged detail view of the deflector operating means. Fig. 4 is a vertical section on line 4-4, Fig. 3.

The radiator comprises a core of transverse tubes 2 arranged on parallel lines and soldered at their ends to end plates 3 through which each end projects in open communication with the vertical passages 4 and 5, respectively, at opposite sides of the casing or shell 6. Separate intake and outlet chambers 7 and 8, respectively, are provided at the top and bottom of the casing, and passage 4 is closed to both chambers by division walls 8, whereas passage is'open to both chambers, and sub-divided between its ends by a division wall or deflector 9 located relatively nearer the discharge or outlet chamber of the radiator than to the intake chamber. Deflector 9 is made in the form of a plate or pair of metal plates with a sealing member 10 of any suitable material extending beyond its edges to contact with the four walls of passage 5 and a downwardly-projecting portion 11 forms a rigid side support for the deflector adapting it to have a slidable movement vertically within said passage. A vertical rack or gear teeth 12 upon supporting portion 11 is engaged by a gear 13 mounted upon a cross shaft 14 which projects through a packing gland member 15 at the rear of the casing and the shaft is bent to provide a crank arm 16 to turn the gear and raise or lower the deflector 9 within passage 5 and relatively to the open ends of the tubes 2. These tubes are flat-sided and of wedge shape in cross section with the larger end located at the rear side of the radiator, and the tubes are also inclined downwardly at their narrow front edges. Therefore, the deflector 9, which is designed to cut off Water communication between the ends of adjacent tubes, is also inclined downwardly at its front end to correspond to the inclination and formation of the tubes, and the deflector may be set at any elevation within the range of the rack 12 and held thereat by frictional engagement with the walls and the water deflected to the opposite passage 4 as any given requirement may demand. In brief, such setting may restrict the outflow of water to a few tubes at the bottom of the radiator, or increase the volume of outflow by increasing the number of tubes for outlet into the lower end of passage 5. In this operation, a corresponding increase or decrease of tubes open to the inflow is brought about, thereby affecting the actual amount of hot water directly delivered to the cooling surfaces in said tubes and affecting the rapidity of cooling of the water accordingly, a result which is .taken advantage of in meeting climatic changes, for example such extremes in temperatures as found in summer compared with the winter season.

What I claim is:

1. A radiator having a vertical passage at each side and a series of transverse tubes open to said. passages, one of said passages being open lengthwise to all said-tubes and the other passage being subdivided near the lower end thereof to restrict the outflow of water from all the tubes to a relatively small number of tubes in the series.

2. A radiator having a series of transverse water-circulating tubes and an adjustable deflectoropposite the ends of said tubes to restrict the outflow of water through a greater or less number of said tubes.

3. A radiator having vertical passages at each side and a series of transverse tubes opening at different elevations into said passages, and a movable deflector in one of said passages adapted to change the relative elevation thereof to said tubes.

4. A radiator having vertical side pas- Iatented Get. 23, 1917. I

sages and a series of wmlge-shapml tubes inclined dowmvardly toward the front of said radiator, and a single division wall in the lower end of one of said passages, subdividing said passage into a large common intake and a smaller outlet for all the tubes.

5. A radiator having a series of transverse Water-circulating tubes and side passages open thereto and a deflector member in one of said passages having means eX- erating extension projecting through the wall of said radiator, and means to prevent leakage at said wall and about said operating extension.

8. A radiator having side passages and a series of transverse Water-circulating tubes open to said passages, a deflector in one of said passages, gear and rack mechanism to elevate and lower said deflector, and means externally of the radiator to operate said mechanism.

9. A radiator having a vertical passage at each side and a series of fla-tsided Wedgeshaped tubes transversely disposed therein and inclined downwardly at their front edges and open at their ends to said passages, and an inclineddefiector adjustably mounted in the lower end of one of said passages opposite the ends of said tubes.

Signed at Cleveland in the county of Cuyahoga, and State of Ohio, this 8th day of February, 1917.
