Specification of Letters Patent.

Patented Feb. 10, 1920.

Application filed March 214, 1919. Serial I'l'o. 284,596.

, To all whom it may concern:

Be it known that I, I'IARRY A. PRELL, a citizen of the United States, residing at Hartford, inthe county of Washington and State of Wisconsin, have invented certain new'and useful Improvements in Radiators, of which the following is a specification.

This invention is a radiator for automobiles, and more especially one of that type having vertical water tubes; and the object of thesame is to prevent freezing as far as possible.

Another object is to provide means whereby a greaternumber of tubes may be opened to the flow of water as the heat of the radiator increases.

Another object is to employ a thermally controlled valve for; changing the course of the water. j

Other objects will appear in the follow-- ing specification and claims, and attention is drawnto the drawings wherein Figure 1 is a central vertical section through this improved radiator.

Fig.2 is a transverse vertical section at right angles to thesectio'nal line of Fig, 1.

Fig. 3 is an enlarged sectional detail of the filling tube and l r Fig. 4 is a sectional detail on the line H Of 3; V

Nofnovelty is claimed for the shell Sof this radiator, itsfilling nipple N and cap C, nor its inlet and outlet I and O. The inlet as'usual leads from the top of the on gine, the outlet leads preferably through a suitable pump into the engine jacket, and water is suppliedfrom time to time through the nipple N as well understood.

- Coming now to the details of the present invention,

partitions

1 and 2 extend across the interior of the shell at about the points shown, the front and shorter water tubes 3 connect and open through these partitions preferably near the front side of the radiator where they are subjected to considerable breeze; and other tubes 4:; 5, 6 and 7 growing respectively longer toward the rear as shown, open also through the lower partition and extendup and completely through the upper partition as shown. The lower ends j of all tubes are by preference restricted as shown at 8 so as to retard the passage of water through them. The upper ends of the tubes 4:, 5, (Sand 7 open through a grade late 9, which is inclined from the rear wall of the shell S downward towardwits front from the ends of the radiator inward toward its center or toward the space 12 as seen in Fig. 1. Above these plates is a chamber 14 yet to be referred to. Beneath the lowerpartition 2 is another chamber 15 communicating with the outlet through a valve 16 capable of being set by hand. A pet cook 17 also opens from a high point in the chamber 15, for a purpose to appear. Finally a large tube or conduitlS connects and opens through both partitions, directly beneath and in alinement with the nipple N and there is an opening through the grade plate 9 directly above this conduit, while of course the space between the baffle plates 10 is above this opening.

. In Fig. 3 is seen a filling tube. a cylindrical body 20 preferably flanged at 21 at its upper end so that it may be dropped into the nipple N, and its exterior circumference is suflicient to permit it to be passed lnto the bore of the conduit 18 at its upper end as seen in Fig. 1. The body 20 is provided with upper and lower series of

openings

22 and 23, the former adapted when the tube is 1n placeto stand ust beneath the nippleand the openings 23 adapted at this time to stand just above the partition 1 and within the space 12 between the two baffle plates 10. A. damper or valve of the butter. fly type 2%. is pivoted within this tube near its lower end, and a rod25 leads upward therefrom and connects with a thermalela meat 26 located within the tube near its. up-

This has per end, the connections being. such that when this element expands the. valve is closed, and the reverse. 1 The action of this improved radiator will be as follows? Having been coupledup, its valve 16 is closed and wateris poured into the radiator to fill the chamber .15 completely full and to stand. well within the lower ends of the tubes and the conduits and then the pet cock 17 isopened and the water now be as much water within the chamber 15 as could be accommodated above the present water level, throughout all the tubes to the overflow indicated at 30. Now when the pet cock is closed and the valve 16 opened, the-water flows into the jackets of the engine, through the pumpreferred to above. As it is drawn around through the pump and driven through the jackets, it flows in at the inlet pipe I under the battle 13, above the partition 1 and beneath the grade plate 9. Flowing into'the openings 23, it passes down through the lower end of the filling tube 18, and again passes through the chamber 15 and onward. Very soon this water becomes warm, and its efiect upon the thermal element 26 is to close partly and eventually to close fully the valve or damper 2%. Now the water flowing in at the inlet must rise within the tube 18 and will flow out the upper openings 22, when it runs over the. plates 10 through this space 12 and down the restricted front pipes 3 into the chamber 15 and again throughout its course. lVith the engine running the capacity of the restricted pipes 3 is not supposed to convey the full volume of water, so that it rises above the partition 1 and flows first through the pipes 4, then through the pipes 5 and so on. Thus more and more pipes are brought into play as the water becomes hottera'nd the circulation more rapid, and of course the more pipes there are brought into use the larger the radiating surface and the greater its effect upon the water flowing therethrough. When th'e'engine comes to rest and the thermal element 26 again becomes'cool, the damper 2-1 will open automatically and the water above the partition 1, if there be any, flows rapidly down the conduit 18 into the chamber 15, because the capacity of the conduit 18 is ample and the flow of water therethrous h is not restricted.

A striking feature of this invention lies in-the fact that when the radiator is working with warm or hot water more and more of the tubes or pipesare in use: but when the water becomes cool and finally cold, the damper 24 opens and all the water collects within the chamber 15, so that the pipes and tubes are drained. It is far safer to permit water to stand and to cool off within a chamher in bulk, than it would be to allow it to stand Within radiator pipes exposed to cold weather and purposely made extremely sensitive thereto, and therefore my invention providingautomatic means for draining the pipes has its advantage" when the car is idle. In summer time the entire filling tube can be lifted; out of place, as its useduring that season is not essential.

The foregoing description and the drawings have reference to what may be considered the preferred or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cctera, as may prove expedient and fall within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1.

2. In a radiator of the type described, the combination with a shell, spaced partitions across the same, certain tubes connecting and opening through the partitions and afiording restricted communication between the chambers above and below said partitions, and an inlet into the upper and an outlet out of the lower chamber; of a series of other tubes opening through the lower partition and extending through the upper partition, their upper ends rising to various heights, a relatively large conduit opening through both partitions, a damper within said conduit, and a thermal element con nected with said damper and adapted to close the same as the water increases in heat.

3. In a radiator of the type described, the combination with a shell, spaced partitions across the same, forward tubes connecting and opening through the partitions and affording restricted communication between the chambers above and below said partitions, and an inlet into the upper chamber and an outlet out of the lower chamber; of
