RADIATOR FOR AUTOMOBILES.

Application ,filed September 15, 1910. Serial No. 582,194.

To all whom it may concern:

. Be it known that I, Hummus KLEIN, a subject of the King of Hungary, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new ments in Radiators for Automobiles, of which the following is a specification.

e present invention relates to radiators .upon motor cars and the like for coolthe Water circulating in the water acket around the engine cylinder.

One of the objects of the invention is to provide a very simple, durable and inexpensive radiator by means of which the maximum cooling effect can be obtained.

Another object of the invention is to provide a radiator in which the joints between the water chambers and the connecting tubes are reduee'dto a minimum.

A further object of the invention is to arthe radiator in such a manner that the greatest possible area of radiating surface of the same is exposed to the air currents.

I With these and other objects in view, which will fully appear as the nature of the invention is better understood, the same conarrangement and combination of' parts hereinafter fully described, pointed out'in the appended claims and illustrated in the accompanying drawings, it being understood that various changes may be made in the size and proportion of the several parts and minor de tails of construction without (.leparting from any of the advanand useful Improveused the spirit or sacrificing tages of the invention.

One of the many possible embodiments of the invention is illustrated in the aceo1npanying drawings, in which:

igure l is a front elevation of a radiator constructed in accordance with the present invention, part of the protecting grate bein removed so as to more clearly show the interior construction of the same; Fig. 2 is a section taken on line 2, 2 of Fig. 1; Fig. 3 is an enlarged front elevation of a pair of fluid tubes; Fig. 4 is a side elevation thereof; and Fig. 5. is a front elevation of a detail of construction.

In the drawings, the numeral 11 indicates the casing of the radiator, which is providcd with an upper water chamber 7, and a lower water chamber 8. .To the upper of to the per and lower ends 16 vThese ends are theneut away in a diametriplane of the U-shaped I l r l 1 l l l chamber leads an inlet tube 9 from the water "acket of the engine,',wl1ile an outlet tube 10 leads from the lower water chamber 8 to the ,water jacket. These two water chambers are connected by a plurality of

tubes

11, 11, which are arranged in pairs, and are, prefer- :ably made of thin sheet like copper or similar material, with their upper and lower ends opening into the clnunbers -7 .and 8, :respectively. The tubes are formed by bond ing the same into an undulating or serpentine form, or in other words at regular intervals in substantially U-shaped form; the

egs

12,12 of each U and also the bases 13 thereof being arranged in a vertical plane and extending throughout the width of the casing 6, that is from the rear grate 1i theregrate like cover 15 of the same. In uniting the tubes l1, 11 into pairs, their up- 'and -16 are bent downwardly, respectively.

upwardly and cal plane which is arranged parallel to the bends or curves so as to obtain senncyhndrical ends, which are united, for instance, by soldering so as to form a sleeve 17 with which both tubes of the pair communicate. Screw threaded nipples l8, 18 are fastened to the bottom 1.) of the water chamber 7 and to the cover 20 of the chamber 8, and communicate with said chambers, respectively. The sleeves 17 of the pairs of tubes are. connected with said nipples by means of

sleeve nuts

20, 20.

lnorder to preventthe accidental disengagement of the sleeve nuts from the tubes and nipples, nut locks are provided, which consist of

fork jaws

22, 22 arranged on their prongs and in engagunent with two parallel'sides of the sleeve nuts. The forks are detachably secured by means of bent wires 23 to brackets 24, which are fastened to the tubes 11.

The cover 15 is provided in its lower edge with

openings

25, 25 adapted to be engaged by the pins 26 upon the radiator casing, while the upper end of said cover is provided with

slots

27, 27, adapted to be engaged by the resilient tongues 28, which are attached to the chamber 7 of the radiator.

It will be observed that the conduits have bends forming circuitous passages for the fluid to be cooled, and that their entire radiating surface is exposed to the air, and thus easily cooled. The tubes are arranged in

shaped members

21, 21 having etc.

What I claim is 1. In an apparatus of the class described,

the combination with the inlet chamber, of,

an outlet chamber, and a plurality of tubes for the circulating fluid arranged in pairs connecting said two chambers and being bent into undulating or serpentine form, each pair of said tubes having a common inlet and a common outlet.

2 In an apparatus of the class described,

the combination with the inlet chamber, of an outlet chamber, a plurality of tubes for the circulating fluid arranged in pairs connecting said two chambers and being bent into undulating or serpentine form, each pair'ot' said tubes havinga common inlet and a common outlet in the form of sleeves, and means engaging said sleeves for fastening detachably said tubes to said chamhers. 3. In an apparatus of the class described, the combination with the inlet chamber, of an outlet chamber, and a plurality of tubes for the circulating fluid arranged in pairs connecting said two chambers and being bent into undulating or serpentine form, each pair of tubes having its bent portions arranged in two parallel vertical planes and being provided with a common inlet and a common outlet.

4. In an apparatus of the class described. the. combination with the inlet chamber, of an outlet chamber, a plurality of tubes for the circulating fluid arranged in pairs contions arranged necting said two into undulatin or serpentine form, each 1 pair of said in es having its bent portions arranged in two parallel vertical planes and being provided with a 'common inlet and a common outlet in the form of sleeves, and means engaging said sleeves for fastening detachably said tubes to said chambers.

5. In an apparatus of the class described, the combination with the inlet chamber, of a plurality of screw threaded nipples communicating therewith, an outlet chamber,

screw threaded nipples in communication with said outlet chamber, a plurality of tubes for the circulating fluid arranged in pairs and bent into undulating or serpentine form, each pair of said tubes having a common inlet and a common outlet in the form of sleeves, and sleeve nuts engaging said sleeves and said nipples for fastening detachably said pairs of tubes to said chambers.

(S. In an apparatus of the class described, the combination with the inlet chamber, of a plurality of screw threaded nipples communcating therewith, an outlet chamber, screw threaded nipples in communication with said outlet chamber, a plurality of tubes for the circulating liuid arranged in pairs and bent into undulating or serpentine form, each pair of said tubes having its bent porin two parallel vertical planes and being provided with a common inlet and a common outlet in the iform of sleeves, and sleeve nuts engaging said sleeves and said nipples for fastening detachably said pars of tubes to said chambers.
