OLIVER BRONN RUTHERFORD, OF BALTIMORE, MARYLAND.

RADIATOR FOR AUTOMOBILES.

Application filed Febrpary 19, 1921. Serial No. 446,380.

To all whoa/t it may concern.

lie it known that 1, Drama 3. tn'rnnnronn, a citizen of the United States, and resident of the city of Baltimore, State of Maryland, have invented certain new and useful Improvements in Radiators for Automobiles, of which the following is a specification.

The invention is designed more particularly to provide a radiator for automobiles, and one object is to enable the radiator to be built up of a plurality of members by using two units, one unit, when assembled with other units of a like character, furnishing the water tubes, and the other unit furnishing the spacing means between the water tubes.

I design to provide a simple construction Which will secure a maximum circulation of the water and a maximum of cooling surfaces exposed to the air.

The invention is shown in the accompanying drawings, in which Figure l is a perspective view of one of the water tube units.

Fig. 2 is a similar view of the spacing unit.

Fig. 3 is a vertical sectional view through the radiator, and

Fig. 4 is a horizontal sectional view on the line 44 of Fig. 3.

In these drawings, the unit which is used to build up the water tubes consists of a plate 1 (Fig. 1) of thin sheet metal having spaced apart horizontal ribs pressed or swaged out therefrom, as shown at 2, leaving recesses at 3 on one face. The vertical edges of these units are offset slightly at a in relation to the main body portion of the. unit, and in making a tube, these offset flanges or edges are soldered together, leaving the intermediate portions of the, plates slightly separated, as at 5, to form the water passage which connects at its upper and lower ends with the heads of the radiator in the ordinary way. The water, of course. enters the recesses 5 and the ribs which provide these recesses furnish an extended radiating surface adapted to be cooled by the air circulation. These water tubes, composed, as stated, of the fiat ribbed plates, are spaced apart by the spacing units shown in Fig. 2, and each of these units is composed of thin sheet metal corrugated so as to provide recesses 6 adjacent each other and facing in opposite directions. The bases of these recesses are fiat and are of considerable breadth, as shown at 7, and one recess is directly adjacent the next recess, being separated therefrom only by the thin wall indicated at 8.

In assembling the spacing units between the flat water tubes, the bases of the corrugations indicated at 7 fit throughout their flat faces against the main body portions of the plates which make up the water tubes and lie between the ribs of the water tubes. They extend over the entire main body portions of the water tube plates and are united thereto by solder, so that the result is the provision of a series of horizontally disposed air spaces or chambers open at their front and rear ends, so that the air may. circulate from front to rear freely and be brought in contact with the curved walls 2 of the ribs and it will be noticed that each air space of the spacing member receives one of the ribs of the water tube.

The water tube is formed by matching its two plates so that the ribs come opposite each other, forming enlarged circular-like recesses, as shown at 9, for the circulation of the water, and its contacts with a considerable area, namely, the wall of the rib which is exposed to the air currents passing from front to rear through the spacing member. The spacing members, as above stated, are formed of corrugated plates, and these plates are of a width corresponding to the width of the plates forming the water tubes, and at the vertical edges the spacing unit is provided with an offset flange or edge on its vertically disposed surfaces, so as to fit upon the ofiset flanges of the plates forming the water tubes. This offset edge of' the spacing plate or unit is indicated at 10 and this is soldered to the edge of the plate of the water tube.

It would seem from the above that two units are utilized in building up the radiator, one unit being the ribbed water tube plate and the other the corrugated spacing plate. By assembling a number of these, as indicated above, the whole nest of tubes and air conducting spacing members are provided to make up the radiator of the desired area.

It will be noted that the spacing members are united with the plates of the water tubes throughout all the vertical contacting surfaces of the said spacing plates and tubes, and in case of leakage into any one of the air spaces, this leak may be stopped by plugging the ends of this particular air space, and there will be no passage of the water from the leak from one air space to another,

because, as stated, the bases of the corrugations are soldered throughout their surface area to the plates of the water tube, and thus one air space will be sealed in respect to the adjacent air spaces of the spacing plate, and there will be no passage of water from one air space to another.

I claim as my invention:

A radiator for automobileshaving Water tubes, each consisting of a pair of spaced apart flat plates, each plate having hollow ribs spaced apart with a fiat portion of the plate between them, said hollow ribs on the opposing plates being arranged opposite each other to form water chambers communicating with each other through the narrow crevice between the opposing flat portions of the said plates, and spacing members between the pairs of Water tube plates consisting of horizontally corrugated sheets, the corrugations being of rectangular form presenting horizontal and vertical wall sections, the latter fitting against and being substantially coextensive with the flat portions of the water tube plates between the corrugations thereof, substantially as described.

In testimony whereof I aflix mv signature.

OLIVER BROWN RUTHERFORD.
