To all lv/tom it may concern i Be it known that I, RICHARD H. HAT- rmLn, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county ofKings and State ofY New York, have invented-a new and Improved Radiator, of whichthe following is a full, clear, and exact description.

My invention relates to an improvement in radiators, preferably of thetype designed to remove the heat from the cooling water of the engine of an automobile or other vehicle, and the primary object thereof is to produce a radiator of this type which will be of simple and practical construction, and at the same time operate with the highest possible efliciency for the purpose in view.

Reference is to be had to the accompanying drawings forming a part of this specification, in which the same characters of reference indicate the 'same parts in all the views.

Figure 1 is a rear elevation of the radiator; Fig. 2 is a horizontal section on the line 2-2 of Fig. 1; Fig. 3 is a plan view of one of the cooling plates through which the radiating tubes pass; Fig.. 4 is a perspective view, showing such a plate with one of the radiating tubes passing through it; and Fig. 5 is a vertical sectional View on the line 5 of Fig. 1, showing one compartment cut ofil from the inlet pipe.

My radiator is indicated as a whole by the numeral 1, and it is provided with a hollow top 2 anda hollow bottom 3, the water entering at the top and passing downward through the radiator tubes which connect the hollow top and bottom together, and from the bottom back tothe water tank of the engine in the usual way.

The top 2 is provided with a number ofY compartments 4, separated by longitudinal partitions 5, and the bottom is provided with compartments 6, separated by longitudinall partitions 7. Each of the upper compartments is provided with an inlet opening surrounded by a pipe flange 8,'and each of the lower compartments is provided with an outlet opening surrounded by a pipe flange 9. The outlet openings at the bottom communicate with a headerp10 connected toa conduit 11, and the outlet openings at the top communicate'with a similar header or conduit, both headers having flanges to enable them to be bolted to the flanges 8 and 9. In case of damage to one or more pairs of upperor lower compartments, these headers are dlsconnected from the correspondingV flanges 8 and 9, and 'a plate 12 having aperl tures near Vits circumference to permit the 'fastening bolts to pass `is inserted between the flanges 8 and 9 and the corresponding flanges on the headers, as shown in Fig. 5. When the fastening bolts are again screwed in the particular upper and lower compartments included in the damaged part of the radiator will be' cut off entirely. In this way, should a collision 0r other accident occur which damages part of the radiator, the' upper and lower compartments adjacent the damaged portion can be put out of commission. I-Ience, vif one, or even two, of the upper and corresponding lower compartments ofthe radiator should happen to be out of commission, the third could still be kept in operation and a suiicient cooling e'ect obtained with this remaining compartment to enable the damaged car to reach the nexty repair station.

The bottom of the upper part 2, shown at 18, and the top ofthe lower art 3, shown at 14, are connected by a num er of radiator tubes 1'5. The tubes 15 are disposed obliquely, or in lines inclined to the axis of the radiator. This is accomplished by arranging the tubes in alined series, the members of the adjacent series being transversely interspaced. By thus arranging the members of the parallel series, and by forming elongated concave surfaces at the forward sides of each tube, provision is made for the delivery of air by each tube and from the concave surface of each tube to the laterallyadjacent tubes and to the pockets formed by the concave surfaces of said adjacent tubes. These tubes are of the shape shown in Fig. 2, and may be described as being triangular in cross section with transversely concaved sides. They are arranged in sufcient number to conduct the`water-or other cooling Huid from the top 2 to the bottom 3, and as the sides ofthese tubes are exposed to the ow of air through the radiator structure between the top 2 and bottom 3, the fluid which passes through these tubes gives up the heat contained therein. The concaved sides of the tubes 15 will permit the expansion of the fluid, and if any of the fluid should freeze .in these tubes, with resultant increase in volume which takes place for example when water turns to ice, the bursting of the tubes will be avoided. j

Between the top 2 and bottom 3 of the radiator is placed a number of horizontal cooling plates 16. These plates are spaced apart and have openings through which the tubes 15 pass. These openings are formed by making a central aperture 17 from which extend radiating cuts 18, these cuts being approximately 120 apart. Bisecting the portion between each two of these cuts 18 are other radiating cuts 19 terminating at their outer ends in apertures 20, and intersected by cross cut-s 21 just short of the apertures 20. The portions of the plate 16 on eachv side of the cuts 19 are then bent, the section between the apertures 20 and the cross cuts 21 forming turned-over lugs 22, and the portion between each cross out 21 and the adjacent radiating cut 18 forming a turned-over lug 23. This will form a plurality of three-point openings through the plates 16, corresponding in shape to the outer contour of the tubes 15, and the lugs 22 and 23 will engage the sidesof the tubes with sufiicient firmness to hold the plates in position. These plates will also have ` lugs 22 and 23 soldered to the sides of the tubes 15, if desired. Each of the pipe flanges 8 and 9 may of course have suitable packing applied to the outer faces of the same when the sections uniting these pipe ianges to the headers 10 are secured in position.

The utility and advantage of my radiator willl be 'apparent from the above description.

If the automobile should meet with a collision, resulting in damage to one, or even two, of the compartments in the top4 and bottom, these compartments can be shut oit and the third compartment kept in use. This third compartment will cool enough of the water from the jacket of the engine to enable the car to reach a repair point, and thus the danger of having the entire radiator put out of commission by injury to a part thereof will be entirely eliminated. Further, the shape of the tubes 15 will prevent bursting in case any of the water should freeze inside of the same, and the horizontal cooling plate 16 will increase the efficiency of the radiator by conducting heat away from the metal walls of the tubes and thus expose a larger area of metallic surface to the action of the air which 'blows through the radiator when the car is in motion. The

conductive action of these plates 16 is increased by the lugs 22 and 23, which bring a larger portion of the body of each plate into contact with the outer surfaces of all of the tubes, and the utmost efficiency is thus obtained. Furthermore, the particular method of forming openings through the plate 16 to give passage to the tubes 15 pro- Vides a resilient engagement of the plates with the tubes, and this resilient engagelnentkowing to the 'frictional surface and bearing of the lugs on the outer surface of the tubes 15, might even be sufficient to hold the plates in position in the radiator under ordinary circumstances. I prefer, however, to solder the plates to the tubes so as to make doubly sure that the plates will at all times retain their proper position with respect to one another.

It will 'be seen from an inspection of Figs. 2, 8 and 4 that incross-sect-ion the tubes 15 have substantially the shape of a trefoil; that is, this cross sectional conguration presents three points or corners joined by transversely concaved sides. This threepointed shape is especially adapted for cooling purposes because of its etiiciency in deflecting the air from the sides of the'tubes in front against the sides of the tubes located more to the rear of the radiator, andthe full cooling action of air which passes through the radiator is thus obtained.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

lA radiator, having a plurality of watercirculating tubes arranged in parallel series, said series being disposed in lines perpendicular to the face of the radiator, said tubes having transversely concaved wall sections disposed lengthwise thereof, the tubes of the adjacent series being arranged in staggered relation to pocket and deflect the air passing between said series, for delivery thereot1 by each tube of one series to the concave sections of the tubes of the adjacent series.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses. v
