This invention relates to radiators and has particular reference to the radiators used on automotive vehicles.
Modern radiators on automotive vehicles f6 are extended well down between the side bars of the chassis frame, to improve the vehicles appearance and' to obtain the effect of depth to the radiator and although this depth is desirable from an appearance standpoint, it is nevertheless not necessary to increase the size of the radiator.A It is therefore now common ractice to use a dummy core below the regu ar yradiator core. This will give the effect desired and at the same time cheap- 5 en the construction for the reason that the dummy core is much cheaper to construct and as it per se forms no part of the actual cooling system, anV injury thereto will in no way affect the radiator system.
The invention is concerned with the construction of the dummy radiator which is placed beneath the radiator core of the engine. The core is constructed by taking a A sheet of flat metal and placing therein a plu- '25 rality of symmetrically and staggeredly arranged cuts or slits and then bending the sheet transversely of and at the ends of the cuts into a plurality of substantially U- l shaped continuous formations. The sheet is then again bent at right angles to the first bend and along the line of each series of cuts. In this second bending operation the sheet is bent back entirely upon itself and in its final form is honeycomb in shape and will give a honeycomb effect, in all respects similar to the honeycomb of the` usual radiator.
Behind the dummy radiator core there is mounted or positioned a plate having a plurality of indentations which are polygonal or diamond shaped. These indentations are preferably .suitably painted and one indentation appears behind each opening in the dummy honeycomb core. This will give a lighting effect as the rays from an oncoming vehicle strike the indentations in the rear plate. The painted indentations form a refiecting surface and the plate may therefore be termed a reflecting plate.
Referring to the drawings:
Fig. 1 shows the lower portion of the radiator of an automotive vehicle with the dummy core shown.
Fig. 2 is an enlarged detail view of a portion of the dummy core.
Fig. 8 is a section through Fig. 2.

Fig. 10 is a section on the line 10-10 of Fig. 8 and showing the plurality of continuous substantially U-shaped bends or formations.
Figs. 11 and 14 are views of successive steps in the formation of the core, the bending operation being continued at right angles to the first and along the lines of the cuts.
Figs. 12 and 18 are sections along the lines 12-12'and 13-13 of Fig. 11.

Referring to the drawings the numeral 2 indicates the conventional honeycomb radiator of an automotive vehicle, 4 the radiator shell, 6 the dummy core and 8 the cap covering the end of the crank shaft. At the rear of the dummy core 6 there is placed or mounted the reflecting plate 8 having the upper and lower flanges 10 and 12 respectively, and lateral iianges, not shown. The upper flange 11') serves asA a dividing or finishing strip between the two cores. The core 6 is secured in the reflecting plate in any suitable way and the plate in turn secured to the shell by means of the welded or riveted brackets 14 and securing means 16 passing through brackets and flanges.
