TocZl whom concern -Be known that we, Locus Biionrnn and Jean Ginasir, citizens of Switzerland, residing at Geneva, Ssdtzerland, have invented certain new and useful improvements in Surface-Coolers for Automobiles; and we do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference merited thereon, which form a part of tliislspecification.

The object of the present invention is to provide an improved radiator or surface cooler for automobiles and. the like for cooling the water used in keeping down the temperature of an internal combustion engine.

- This radiator consists of a series of hollow corrugated or any other similar form of sections which are arranged preferably in parallel. relation between two water cl1amhers, one for warm water and the other for the cooled water, and'the invention-consists in the particular construction and arrangement of the sections and the manner in which they are held, whereby a strong device is economically built up, which also has the advantage of presenting a large radiating surface.

The invention is illustrated in the accompanying drawing, in whichl igure l is a part front elevation of a set of radiator sections an the plate holding them. Fig. 2 is a part vertical section taken on line 51 y in Fig. 1. Fig. 3 is an enlarged elevation or part of a plate used for hold ing the sections, the plate being illustrated before it has been punched. Fig. 4 is a horizontal section through a set of sections, and Fig. is a section of the front plate taken ,on line 3 c, in Fig. 3 after the perto-rations have been punched in the plate.

'F shows a portion of a plate with dift'orent shaped perforations therein.

The radiator is formed of a large number of sections arranged. preferably in parallel relation, and they are arranged so as to connect two water chambers which are not shown in the drawings, These water cha1n-. hers 't'orm part of the framework of the appsratus are connected and communicute with each other through the seocorru ated folded overon the edge of the other, al-

-holding means for claspingor holding the o end usually rectangular in shape and are made. up of'two very thin metallic sheets maintained at El. small distance apart and their edges, being preferably united along avlng one of the thin sheets united by though the particular means of securing the edges of the plates forming the sections is not essential. The sections are curved to prevent the pressure of the water inflating 3 thorn and thus reduce the air passages be tween them.

The radiator sections a are open on the top and bottom where they are soldered to the water chambers for the passage of the water through them, and their corrugations Z) are inclined so t-hat they tend to direct the water to the front of the cooler, where the cooling action is greatest, andin order to facilitate the passage of the cooling air between the sections, said air tending to rise as it gets warm. The distance between the sections is maintained at one edge of the sections by transverse bars 0, these bars being note ed to receive the sections and pref erably soldered thereon. At one end, and preferably the front end, the sections are held by the front plate 05 which is made of 3 a thin metallic plate perforated by forcing. in the edges of the perforation whereby sir passages are formed through the perforations to permit the air to pass between the sections. The perforations are preferably made by bending down the'fou r triangular parts of the squares shown in dotted lines in Fig. 3. On oppositesidesof the squares the wings f are formed by the inturned edges of the perforations, the wings of two adjacent perforations forming parallel ends of the radiator sections as shown more particularly in Fig. 4C. This serves to hold the sections and also forms a n1 ans for so curing the plate to the sections and strengthening the whole structure. The intermediate wings f, normally disposed at right angles to the wings 7, project to insure the distance between the sections. This perio ruled plate f also gives the radiator a neat appearance resembling the honeycomb type of radiator. In Fig; 6 the perforations shown of i1 rectangular shape in order to diminish the number of wings f and in crease the air passage.

Having thus described our inventioii what we claim is l. A radiator-comprisingradiator sec tions, and a front plate being provided with' perforations, the edges of the perforations being turned inward so that the inturned the radiator sections.

edges of adjacent perforations will clasp 2. A radiator comprisin radiator sec,-

ing their edges'turned to form wings, the wings being adapted to clasp the edges of the sections between them.

I 3. A radiator comprising radiator sections having downwardly and forwardly inclincd corrugations, and a front plate havmg perforations with inturned' edges, the

mturned edges of adjacent perforations being adapted to clasp a radiator section between them.

' 4. A radiator comprising a series of radiator sections, each section being formed of corrugated plates joined at their edges, and

a front plate formed with perforations, the

- edges of the perforations being turned in to form Wings, the adjacent wings of adjoining perforations being adapted to embrace the joined edges of the radiator sections.

5. A radiator comprising radiator sections' of comparatively thin form, and a front plate havin a series of perforations therein, each per oration being formed by bending down four triangular abutting parts, the triangular parts forming wings for clasping the edges of the radiator sections.

6. In a radiator a front plate having perforations formed therein, the edges of the perforations being bent at an angle to the plate to form means for clasping radiator sections between them.

' In testimony, that we claim the foregoing,

We have hereunto set out hands this thirtieth day of July 1909.
