WATER-HEATER.
Specification. of Letters Patent. Patentgd Mimi. 30, 1920.
Application filed February 26, 1918. Serial No. 218,212.
1 0 all whom it may concern Be it known that I, EDWARD T. GURRAN, who am a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in VVater-Heaters, and declare the following to a full, clear, and xact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to water heaters ordinarily termed as instantaneous water heaters to supply a quick or instantaneous hot water supply or for a hot water heating system, and under certain conditions may be utilized as a steam generator, and it is th object of the invention to provide a heater of this character which is simple and cheap in construction, and to provide a novel combination and arrangement of parts to produce a heater which is highly efficient in operation.
In the drawing accompanying and form ing a part of this specification, Figure 1 is a longitudinal view, partly in section, of a water heater showing an embodiment of my invention.
Fig. 2 is an enlarged sectional view of a portion of the heater to show the internal arrangement of the same and the connection of one element to another element thereof; and
Fig. 3 is a cross sectional view taken on the line 3-3 of Fig. 2 looking in the direction of the arrow.
Similar characters of reference designate like parts throughout the diiferent views of the drawing.
In carrying out the embodiment of the invention shown in the drawing I provide a pair of nested and spaced apart cylindrical shells 4, 5 with the lower end of the outer shell flanged inwardly, as at 6, and welded to the projecting end of the inner shell to provide a water carrying jacket A. The lower end of the inner shell 5 is open and is arranged for a burner B for a gaseous fuel. The space within the shell 5 constitutes a combustion chamber having an outlet at the top for the products of combustion comprising a pipe E passing through openings in the shells and welded thereto, said pipe also serving to maintain the shells in spaced relation, and may be connected to a flue or chimney, not shown.
A water'lieating unit is inclo'sed within the water j acket and comprises a series of superposed, spaced apart and connected truncated cone shaped annular water chambers or jackets, shown as four in number K, K, K and K although a greater or less number of these chambers may be utilized if desired. These chambers consist of spaced shells L, L (Fig. 2) inclining downward and outward at an acute angle relative to the aXis of the water jacket A with the outer wall of the chambers at the base fitting preferably snugly to the shell 5 of the water chamber A.
The lowermost chamber K which is directly above the burner B has a clear and unobstructed opening therethrough, while the chambers K K and K are each provided with a circular though comparatively flat water chamber N located concentric within the enlarged ends of saidchambers and connected with the chambers in water circulation at substantially diametrically opposite sides by hollow legs M, M. These chambers N, P, P form baflles and obstructions for the free passage of the. heat of combustion through the interior of the chambers and cause the same to take a tortuous passage about the said chambers through the combustion chamber.
The chamber K is connected in water circulation with the chamber K by pipes M, M, similar to the manner as shown in the connection of the chambers K and K in Fig. 2, though only the connection M can be seen in Fig. 1, the pipe M being diametrically opposite. The pipe M communicates with the annular chambers K and K whil the pipe M communicates withtho annular chamber K and with the circular chamber N of chamber K as shown in Figs. 2 and 3. I
The chamber K is also connected in water circulation by means of the pipes M, M with the chamber K, but which are located at right angles to the pipes connecting the chambers K and K as clearly shown in Fig. 1. The connecting pipe M from the chamber K communicates with the circular baffle chamber N of chamber K, while the pipe M communicates with the annular water jacket of the chamber K. The chambers K and K are connected in water circulation in a similar manner except that the connecting pipes are located substantially at right angles to the pipes connecting the chambers K and K and similar to the connection of the chambers K and K.
A circular and comparatively fiat water chamber R is located above and spaced from the uppermost water chamber K and connected in water circulation therewith by pipes Q extending in a vertical direction, the diameter of this chamber being substantially the same as the smaller end of the cone shaped chambers. The heating unit built up by the respective annular water chambers is connected to a source oi hot water supply, or in circulation with a hot water heating system, by a pipe -D leading from the circular chamber R and extending through the water chamber A. The heating unit is connected to a source of water supply by a pipe. 0 shown as leading through the water jacket A and connected to the lowermost chamber K of the heating unit. The passage of the water through the chambers of the heating unit is substantially as indicated by the arrows in Fig. 1.
To provide a supply of water to the jacket A and induce a circulation of the water through such jacket and the heating unit, the chamber or jacket A is connected to the heating unit by a pipe F leading to the chamber K and a pipe R leading to the chamber K although it is evident that each of the chambers constituting the water heating unit could be connected in circulation with the jacket A. The water jacket also has a connection with the outlet pipe D by a port G- in said pipe in communication with the jacket A. The water jacket A may also be provided with a drain cock H.
The cone shaped annular chambers and the connecting pipes M, M are preferably made of an integral structure by welding the parts together and thereby providing an inexpensive and ellicient water heater.
In operation and utilizing the heater for a hot watersupply the annular cone shaped chambers of the heating unit and the jacket A are maintained in connection with a water supply through the connection 0, which may becontrolled by a stop cock, not shown. The fuel is then ignited at the burner B the products and heat of combustion passing up through the chamber K into and through the space between the next cham ber K and in such passage impinges against the hollow baflie member N, passing around said member and the pipes M, M, as shown by the arrows in Fig. 2; thence they pass through the chamber K to the next chamber K and in such travel pass around the pipes M, M connecting said chambers and impinge against and pass around the bafiie member N at the bottom of said chamber K, and thence passing through chamber K and impinging upon the baffle member N of chamber K, and through said latter chamber K, whence they impinge against the chamber R and are deflected thereby around the pipes Q and the outlet pipe D to the space above said chamber R to the outlet flue E. By this tortuous passage of the heat and products of combustion practically all. of the heat is absorbed by the dilferent chambers of the water heating column or unit. hen utilizing the apparatus in connection. with a hot water heating system after the heating unit and chamber A is filled with water they are shut off from the source of supply, the inlet C for the chamber K being arranged as the water return.
