Application October 21, 194s,seria1 No; 55,738

My present invention relates towater heaters, and more particularly to connecting means 3 Claims. (01, 257-252)' for connecting the open ends of consecutive pairs of water tubes with each other.

It is an object of my present invention to provide connecting means which are adapted not only for connecting one pair of water tubes but i adapted to connect a plurality of pairs of water tubes with each other in such a manner that the-tubes forming each consecutive pair of tubes are connected with each other but that each pair of' connected tubes is independent anddivided from the preceding and following pairs, of tubes.

It is another object of mypres ent invention to provide connecting means which are simpl in construction and manufacture.

Finally, it is also an object of my present invention to provide unitary connecting means foria great number of tubes which areinexpensive to manufacture.

With the above objects in view, my present invention mainly relates to a water heater provided with a plurality of parallelly arranged water tubes and connecting means for connecte ing the open ends of consecutive pairs of these tubes with each other; as proposed by me, these connecting means comprise in combination a longitudinal connecting member having a U- shaped cross section being substantially hollow from one end thereof to the other and, having a fiat top face facing the open ends of the water tubes, arrow of round openings in'the flat top face of the longitudinal connecting member arranged at ia -smallgdistance from each other "in longitudinal direction of the longitudinal connecting member so that each of the plurality of .nal direction of the longitudinal cover strip so that each of the plurality oi water tubes is adapted to fit into one of 'the openings andtobe secured Ywater-tightly. within the same, and a plurality "of dividingwalls arranged within-thez' longitudinal channel member in transversal directionof the same spaced from each oth'er in such a manner as to form within'the' longitudinal channel member consecutive channel compai't ments water-tightly divided from each other and having each of such a length as to communicate with two consecutive openings in the longis tudinal cover strip.

The'novel features which I consider as chai acteristic for my invention are set forth in the The invention itself, howappended 7 claims. ever, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of a specific'embodiment when read in connection with the accom'f panying drawings, in which:

-Fig. 1 "is'a perspective view of apart of a water heater according to my present invention;

and

- Fig. 2 is a longitudinal sectional view on line 2-2 in Fig. 1. V In the water heater arrangement shown in Figs." 1 and 2, the water tubes I0 are arranged parallel to each other. The connection between V the tubes of consecutive pairs of Water; tubes is water-tubes is adapted to'fit into one of theroundopenings and .to be water-tightly secured 1 therein, and a plurality of dividing walls ar ranged withinth longitudinal connecting member in transversal direction in such a manner as to form within the longitudinal connecting member compartments each of which communi cates with one of the consecutive pairs of the water tubes.

In accordance with a preferred embodiment of my present'invention, the new connecting means comprise a longitudinal channel member being open at its top and having two lateral top edges, a' longitudinal cover strip water-tightly secured along its edges to'the lateral top edges of the longitudinal channel member, a row of openings in the longitudinal cover strip arranged at aslight distance from 'eachother in longitudiobtained by the connecting channel-shaped member 26.

This channel shaped member 26 is simultaneously covered and subdivided by the com-, bined cover and dividing strip 21 which hastop portions 28 and downwardly bent dividing portions29, 'Ihe end wal1s'30 are also bent out of strip 21. I 'Ifhe edges of the strip 21 are firmly- Ibrazed to the channel member 26 so asto form separate compartments 3|. The channel-shaped member 28 includes two side wall'portions 25 which-are substantially parallel, and a connect-:-

ing wauportion 24.,

Each'of the top portions 28'of strip- 21 is provided with two holes 32 into which fit th water tubes ID as indicated in dotted lines. Each pair of water tubes m communicates through one compartment 3!.

n It should also be stressed that although I have described above my new connecting means only as adapted for connecting heater tubes in a water heater, the samemightalso be used for connecting other types of tubes, e. g, tubes through which gases or air are passing.

can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior 'art,"f-airly constitute essential characteristics ofthegeneric 1 or specific aspects of this invention, and, there-' fore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence'of the following claims.

What I claim as new and desire to secure by Letters Patent is: 7 V 1. In a water heater provided with a plurality of 'parallelly arranged water tubes, connecting means for connectingthe open ends of the tubes of consecutive pairs of said water tubes with each other, said connecting-means comprising in combination a longitudinal channel member including two side wall portions extending substantially parallel to each other through the entire length of said channel member and having two top edges, and a connecting wall portion integral with said side wall portions and connecting the same along the entire length of said channel member, said channel member being open at its top and at its opposite ends; a longitudinal cover strip water-tightly secured along its edges to said top edges of said side wall portions of said longitudinal channel member; a row of openings in said longitudinal cover strip arranged at a slight distance from each other 'in longitudinal direction of said longitudinal cover strip so that each of a said plurality of water tubes is adapted to fit into one of said openings and to be secured watertightly within the same; a plurality of consecutive bends in said longitudinal cover strip forming a plurality of transversal Walls extending normal to the direction of said longitudinal cover strip and reaching into said longitudinal channel member in such a manner as to form within said longitudinal channel member consecutive channel compartments water-tightly divided from each other and having each such a length as to .communicate with two consecutive openings in said longitudinal cover strip. 7 2.- In a'water heater provided with a pluralit of parallelly arranged water tubes, connecting means for connecting the open ends of the tubes of consecutive pairs of said water tubes with each other, said connecting means comprising .in combination a longitudinal channel member including two side wall portions extending substantially parallel to each other through the entire length of said channel member and having two top longitudinal channel member so that said bent transversal wall portions reach into said longitudinal channel member dividing the same into :a plurality of consecutive channel compartments water tightly'divided from each other; and a row of openings insaid longitudinal cover strip ar--' ranged in longitudinal direction thereof in such a manner that each strip portion between two consecutive bends is provided with two openings.

3. In a water heater provided with a plurality of parallelly arranged water tubes, connectin means for connecting the open ends of the tubes of consecutive pairs of saidwater tubeswith each other, said connecting means comprising in combination a longitudinal channel member includingtwo side wall portions extending substantially parallel toeach other through the entire length of said channel member and having two top edges, and a connecting wall portion integral with said side wall portions and connectin the same along the entire length of said channel member, said channel member beinglopen atuits top; a

longitudinal cover strip provided 'witha plurality a manner that'eaoh strip portion between two consecutivebends is provided with two openings; and end walls at both ends of said longitudinal channel member secured to the end edges of the same and of said longitudinal cover strip watertightly closing the open ends of said longitudinal channel member.
