RADIATOR.

No. 895,767'. Specification o Application filed April 5,

To all whom it may concern.-

Be it known that I, THOMAS J. KEHOE, a citizen of the United States of America, and resident -of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in .Radiators, of which the following is a specification.

his invention relates to improvements in radiators of that class used in connection with automobiles for reducing the temperature of water ordinarily employed for cooling engine cylinders 3 andthe object thereof is to afford a device of the class described which will be highly efficient and durable.`

The object of this improvement is accomplished by the construction illustrated in the accompanying drawings, in which:

' Figure 1. is a rear elevation of the with a part thereof broken y a cross section of the same. on the line of Fig. 1.; Fig. 3. is a detail showing a portion of one of the radiating sections and also a portion of the adjacent tank; Fig. 4. is a detail of a portion of one plates, Fig. 5. is a similar view showing a modified form of radiating plate; and Fig. is a detail in perspective showing a portion of one of the radiating sections. .f

Similar numerals of reference indicate co responding parts throughout the several radiator awav; Fig` 2. 1s

views, and referring now to the same: 1 and mounted in place upon the tive ends with the l, a radiating 2 are upper vand lower tanks respectively which are connected at their ends by standards 3, each of the latter having a side bracket 4 by means of which the device is frame ofthe au toinobile. or other foundation. The tanks 1 and2'eaeh have a pipe 5 leading thereinto for suitable connection with the water circula-ting system of the engine or other contrivance.

A multiplicity of flat hollow sections 6 are arranged between the upper and lower tanks, andeach section is connected at its respecadjacent tanks and affords communication therethrough from one tank to the other. The said sections are each formed with a lap seam 6 at its respective edges, which afford reinforcement.

Upon each side of each section 6 is secured plate 7 from the. outer face of which protrudes' numerous tongues 8. The ngues are formed by cutting through the e and pressing a portion thereof outward f Letters Patent.

l from the general plane of its surface, but l without severing the inner end of the tongue I from the body of the plate, thus leaving an opening 9 in' the yplate beneath each tongue. l The plates 7 are united to the sides of the l sections 6 respectively by means of solder so l that they thereby becomeas an integral part l thereof, and with the tongues 8 protruding l outwardly. In the tank 2 is arranged a pipe 10 which has communication with the corresponding pipe 5 which leads from said tank. A number of perforations 11 are made in the pipe 10 at points coincident with the lower ends of the respective sections 6 j and a similar pi e 12 (shown in dotted lines) is arrange in the tank 1 and communicates with the corresponding pipe 5. The object of the

pipes

10 and 12 is to afford water through the various sections.

The tank l has acap 13 at its top which, when removed, affords an opening for filling l the radiator with water,` and the tank 2 has a screw plug 14 in ,its bottom which, when removed, affords an opening for drainage.

In Fig. 5. of the drawings is shown a modified form of radiating plate. In this form the plate is similar to that in the former instance in all-respects except that those portions 15 which intervene between the tongues `16 are arched outwardly so as to project` from the side of the section to which theplate is attached.

In the operation of this invention the

tanks

1 and 2 are connected by means of the pipes 5 with the corresponding pipes of the water circulating system as above described, and as the heated water passes through the sections 6 from one tank to the other because of gravitation (or other force as the case may be), the heat of the water will be more or less drawn therefrom by direct contact with the sections 6, and by convection afforded by the tongues Symto the open spaces between the sections. Air of lower temperature than the water con'- tained in the sections is caused to pass naturally or by force between the various sections, andin s0 passing absorbs the heat drawn from the water within the sections by the metallic tongues, and furthermore carries away the heat induced by radiation from the external surfaces of the sections and plates. Thus water in passing through the sections is deprived of its contained heat by the circulation of air assisted by the processes of both radiation. and convection.
