UNEESTRIGTED-REEUEN WATER HEATER.
Application filed July 1?,l926. Serial No. 123,228..
My present invention relates to the provision of a type of water heater in which the heat transfer elements consist of one or more pairs of converging-or diverging tubes communicating at their converging ends and secured in a transverse plate at their divergends. The heat transfer elements are associated either in a single pair or in a plurality of pairs with an exterior head to receive the exterior connections for supplying water to and conveying it from the heat transfer elements, and means are provided. for securing the head and the transverse p ate the heat transfer element or ele- -ents about the edge of a suitable aperture in boiler or other chamber in which water or other heated element is contained so that e tubes of each pair w ll be disposed ver with respect to each other.
he divergent arrangement of the tubes of the heat transfer elements at their outer facilitates both a gravitational and assure circulation therethrough. it have lso secured a iuncture hetween the tubes of one heat transfer elements at their converging ends by means of a structure the parts ereof are brazed together and the ends the tubes so as to provide even a greater aacity at the place of iuncture than either no separately or both together would aford. This arrangement is important this avoidable bend in the path of travel of e water during the heat transfer process 0 ers greatest impediment a gravita i circulation, and by inalrin the inns etween the ingoing and on. ,"oing tubes I heat transfer portion 0.. greater caboth improved circulation the system and improved junta iccordingly as one or more nairs of heat refer tubes are assembled at their diverg ends a single transverse plate they be employed with a number of different ior heads to facilitate assembly with ocular hot water circulatino system and the purpose of increasing the capacity the apparatus for furnishing hot water. The design of structure heretofore referf rred to is illustrated in the accompanying drawing, in which Fig.1 is a side elevation, largely in cen tral, longitudinal, vertical section, of a complots assembly .of a pair of heat transfer tubes with an exterior head and boiler plate;
Fig. 2 is a front elevation of the structure shown in Fig. l;

Similar reference characters have been can ployed throughout the several views to olesi diverging relation by means of an anterior r front plate. l7. a posterlor or remote uncture casing, a
' anterior plate, l7, bored or othen wise perforated the passage the forward ends of the transfer tubes there through and issecured to tubes short distance back of their front ends by braz ing or sweating or in any other desired man ner.
The remote, or posterior ends of the heat transfer tubes are provided a short distance infront of their rear ends with an exterior use. 19 The member for securing a junc ture between the rear ends ofthe heat transfer tubes is formed by taking a suitable till too
lift) length, 20, of a much larger tube and deforming it until it is of an voblong outline, as shown in Fig. 5. The centers of the forward edges of this length of tube 20 are inwardly compressed, as shown at 21 in Fig. 3, to enter between the converging ends of the heat transfer tubes 15 and 16. The rear edges of the heat transfer tubes are beveled as shown at 22 in Figs. 4 and 6, and when the heat transfer tubes are inserted in the front end of the length of tube 20 up to the beading l9, spelter is placed in the recess formed by the bevel 22 and the whole is heated until the above described parts are sweated together. A very good and dependable joint can be formed as above described, whereas if this operation is attempted by flooding the joint from the outside it will probably result in dissolving and removing some of the metal of the tubes 15, 16 or 20 in the hot spelter.
After this interior brazing has been done, a beveled rear end plate, 23, is inserted in the length of tubing 20, and spelter is again placed in the cavity formed by the bevel, when a final heating secures the entire structure in a unitary or integral mass of ample strength and large capacity, relative to the capacities of the tubes, and a somewhat more extended surface to which the surrounding heated medium transmitsheat by conduction. In Figs. 1 and 2 is shown a form of head which is extremely simple and which is arranged to take the feed and discharge pipes directly into its face. This form of head comprises a casting 24 extended to provide ears 25 at its two opposite ends, which ears are perforated, as at 26, for the passage of stud bolts 27 tapped into the boiler plate 28. The forward face of the casting 24 is substantially Hat and this is bored and tapped at 29 and 30 for assembly with the supply and discharge pipes. The bores 29 and 30 communicate with interior chambers 31 and 32, separated by a partition, 33, which extends rearwardly into the plane of the rear of the head. The chambers 31 and 32 open rearwardly through apertures 34 and 35 and the reariace 36 of the casting 24 substantial- 1y registers with the forward face of the plate 17 heretofore described.
The boiler plate is apertured at 37 for the passage of the tubes 15 and 16 and a soft metal gasket 38 is employed between thev rear face of the plate 17 and the boiler plate which gasket, 38 has a lateral projection 0r r1b. 39, extending into the aperture in the boiler plate so as to prevent contact between the tubes 15 and 16 and the boiler plate.
Another soft metal washer, 40, is interposed between the forward face of the plate 17 and the rear face 36 of the casting 24. Nuts 41 on the outer ends of the stud bolts 27 hold-the castings 24, plate 17, and washemma ers 38 and 40, firmly to the boiler plate, 28, with any degree of force which may be desired.
The head shown in Figs. 9 to 11 inclusive, is similar to that shown in Figs. 1 and 2 in all essential details except the body portion of the head 24 has extending therefrom a neck 42 on the outer end whereofis an enlargement 43, bored and tapped in its face at 29 and 30, and also laterally both in its bottom and top at 44 and 45.
In the head shown in Figs. 9 to 11 inclusive, it appears how, by merely enlarging the rear opening 34, the same head ma be used for one or a plurality of pairs of cat transfer tubes 15 and 16.
It should be noted that in each form of head the internaltransverse partition 33 d 33 is transversely bored as at 46 and 46 to provide a bleed hole so as to ermit the flow of any air released from t e water from lower compartments 31 and 31 to upper compartments 32 and 32 from which an such air is immediately discharged throng the discharge connection.
1n Fi 12 is shown in tragmental detail the relatlon of the juncture casings 18, when two pairs oil heat transfer units are em= ployed in a single head.
As will be seen from the foregoin de scription taken in connection with the ol awings, each pair of heat transfer tubes 14- and 15 are disposed vertically with respect to each other and at a slight angle to each other, so that when the axis of these tubes is arranged horizontally the conduit provided by the tubes and their juncture casing 18 either rises or falls throughout its entire length' This facilitates both the gravitational and pressure circulation through these tubes, and the juncture casing 18, havin a capacity larger than either, of the tu es.
taken separately orcombined, acts as a die terrent to circulation at the bend or change of direction in the flow as little as possible.
