Application filed July 15,

To all whom it may concern:

Be it k nown that I, Gnonen L. LAKE, a citizen of'the United States, resident of New Market, in the county of Taylor and State of Iowa, have made a certain new and useful Invention in.Automobile-Radiators5 and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in. the art to which it appertains to make and use the invention, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

F igure" 1. is a front view of the invention.

Fig. 2f 1s a section.on the line 2-2, Fig. 1, molar} d and partly broken away.

Fig. I is a detail cross sectional 'view of several of the radiator tubes.

The invention has relation to radiators for the explosive engines of motor vehicles, having for an ob'ectto provide improved radiator tubes adapted to expand under pressure and thereby resist burstin to increase the water capacity of the radiator; to arrange the radiator tubes in such manner as to lncrease the circulation of the air rela tive to each tube and thereby facilitate the cooling of the water contents of the tubes; and to provide the radiator casing with removable front and back plates, and the radiator tubes with longitudinal scams or joints facing forwardly and rearwardiy and readily accessible for repairing in case of bursting.

The invention consists in the novel construction and combinations of parts, as here inafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 2- designates the hollow top of the radiator casing; 3 the hollow bottom thereof, and 4, 4 the up;

right series of tubes connecting the top and bottom, the frame of the casing comprising also sides 5, 5, connecting top and )ottom thereof, and intermediate horizontal partitions 6, 6, being used to assist in maintann ing the tubes in proper relation.

The front of the casing of the radiator is provided with a recess 7, wherein. fits a re movable front plate 8,- having the usual openworh formation, and the rear or back is also provided with a recess or seat 9, wherein fits a removable back plate 10, of openwork formation, horizontal bolts Specification of Letters Patent; Pate Sept 1920. Serial No. 396,394.

11 engaging apertures 12 of the sides of the raising and having each one end threaded at l3 into apertures of the removable front, 7 and the other end engaging apertures it of the removable back and threaded for enga ement of nuts 15.

"he radiator tubes are arranged in iii-- clined series 16, each series having a central. bend" 16 therein, whereby it is divided, into two wings or branches 1.7, 17, ungularly die posed, and each series of tubes is coni 'iosed of members arranged close together. "lhe series of tubes, bent or bowed as stated, are spaced apart by bowed intervals 18 consider" ably wider than the spaces 19 separating the members of each series. As a result, the air currents passing through the radiator not [iii only have more direct impingement upon the tubes, but the passage of the air currents in straight oaths through. the radiator cue ing is guart ed against to a maximum tent.

Each of the radiator ,tnbes is made of sheet metal, bent into form and provi with a longitudinal seam or joint 20, whici'i. in the case of the members of the wing or branch of the bent series nearest the remov able front of the radiator casing is arranged to face said front, and in the case of the wing or branch of the series nearest the re-- movable back of said casing is arranged to face said back, whereby, should a breal de velop in any of the tubes, it will be readily accessible for repairs, upon removing the front or back of the casing, as may be needed.

Each of the radiator tubes is made in squared or quadrangular form, with a corrugation or groove 21 in each side, the metal. of said corrugation or groove being ea tllie'l ble under pressure, and thereby resiemur; bursting.

I claim e .1. An automobile radiator, hm plate, a rear plate, upright radiate arranged in inclined seri each ing a central bend. and :ii'ignlarly d branches, and a. hollow top and. a bottom having communteat-ion with lid tubes, side frame pieces connectng said "top and said bottom, said tubes being or sheet 3.

El ti plate, a rem plate, upright tubes arranged in inclined series, each series haviu" a, centml bend and angular iy disposed branches, and n hoilow top and a hollow bottom having com'nnmicst-ion with said tubes, side frame pieces connecting said top and said bottom, said tubes being of quadrangular form provided with h. ,gitudinally grooved sides expa-nsible under pressure, the tubes being .of sheetimeml and lmving longitudimew e4:

nal joints l accessible from the from and rear of the 131111121201: upon removuf of" Him front and of i he rear plum In testxmony whereof I ufii); my :31 gnnmru 1n presence of two wltnessos.
