3 Claims.

This invention relates to water heaters, and in particular storage automatic water heaters of the type in which the heat of a gasburner is applied directly to the storage vessel or water container.

It is the object of this invention to provide in a heater of the type disclosed, an improved combustion chamber housing which is arranged to facilitate the assembly of the heater as well as certain other improvements relating to the means for mounting the burner and the arrangement and construction oi. the door provided for permitting access to the stated combustion chamher.

With these and other objects, in view, the invention consists in the novel construction, arrangement and combination of parts, hereinafter described, illustrated in some of its embodiments in the accompanying drawings and particularly pointed out in the appended claims.

In the drawings, Figure l is a side elevational view partly in section of my improved water heater.

Figure 2 is a sectional view taken on line 2-2, Figure 1.

Figure 3 is an enlarged side elevational view showing the combustion chamber housing and the door means provided for permitting access to the interior of the combustion chamber.

Figure 4 is a sectional view taken on line 4-4, Figure 3.

Figure 5 is a side elevational view showing the inner side of the door assembly with the door in its closed position and Figure 6 is a side elevational view taken on line 6-43, Figure 5 illustrating the means by which the combustion chamber door may be held in its open position.

The heater illustrated by Figure 1 comprises a storage tank I, which is arranged to be connected to a cold water supply conduit 2 and a hot water outlet pipe 3. The storage container l is surrounded by a casing 4, which is spaced a short distance from the walls of the tank I, so as to provide a passageway thereabout for the heated products of combustion from the source of heat provided for the appliance.

The inner casing 4 is surrounded in turn, by an outer casing 5. The space between the casings 4 and 5 may be filled with a heat insulating material if desired, as is customary in such heaters. A gas burner 6 is positioned below the bottom of the tank I for the purpose of heating the water in the tank. The heated products of combustion produced by the burner 6, flow upwardly through the space between the inner casing l and the tank I, and are vented from the appliance by way of a flue I, which is connected to the top of the heater.

The cold water supply line to the tank I, includes a dip pipe 8, terminating adjacent the tank bottom, whereby the incoming water is directed against the bottom of the tank and does not become mixed with the hot water in the upper part of the tank.

A gas supply-conduit 9 conducts gas from a source of gas supply to the burner 6. A continuously operating pilot burner III, formed integrally with the main burner 6 is provided for igniting this burner. The pilot burner III is supplied with gas by way of a conduit II, under control of the manually operable valve I2. able shut-off valve I3 is provided ior manually controlling the operation of the main burner 6.

A tank temperature responsive thermostatic valve I4 cooperates with a pilot governed thermostatic valvel5, to automatically regulate the supply 01 fuel to the burner 6 in accordance with the temperature of the water in the tank I, and under control of the pilot burner III. The thermostatic valve I4 is secured in a tapped opening I6 provided in the wall of the tank I, and the valve I5 is secured in position in a manner to be described in detail presently.

The housing defining the combustion chamber for the burner 6, is formed from three castings which include a front casting I6 and two rear castings in its construction. The front housing casting l6 has an opening formed by four outwardly extending flanges I8, to which is secured a door assembly. This assembly comprises an apertured plate or frame I9, to which is secured a spring hinged door 20 and a plate 2|.

The frame I9 and the plate 2| have matched cut-out portions to provide suitable openings 34, 35 and 36 for receiving the parts associated with the thermally actuated valve I5, the pilot supply conduit II and the burner 6, whichextend into the interior of the heater combustion chamber. The door 20 is hinged to a rod 22, carried by the frame I9, and is provided with a closure spring 23 for maintaining it in its closed position.

A weighted bell crank 24 is pivotally mounted on a pin 25, carried by the door 20. The weighted end 28 of the crank is arranged to cause the crank to assume the position shown in Figure 6 when the door is opened. In this position the unweighted end of the crank is in engagement with A manually operthe frame IQ for maintaining the door in open position.

Closure of the door may be efiected by either raising the weighted portion 26 of the crank, or by opening the door still further and letting it snap shut under influence of the spring 23, whereupon the bell crank is jolted to the position shown in Figure 5 as the door closes. This effect is made possible by forming the unweighted end of the bell crank with a cam face 31 and by having the weight 26 just balance the crank when it is in the position shown in Figure 6. The same effect could be achieved by forming the bell crank 2d so that when in a state of stable equilibrium or in balance, its upper arm would form an acute angle with the horizontal.

The casting I6 is provided with slotted'ears 27, which cooperate with cars 28 and 29, formed on the opposite ends of the sections ii, to hold the housing elements in position. The slots of the matched ears cooperate to provide bolt holes 359 for the bolts 38. By the use of slots instead of circular holes an adjustable feature is provided whereby the housing may be readily assembled even though there are slight variations in the elements i6, i1 and IT as always occurs in castings of this size. The bolts 38 serve the triple purpose of securing the casing elements to each other, securing the casing elements to the base 39, and securing the legs 3! to the base 39.

"he housing elements It and H are each formed with an inwardly projecting lug 32 and d2 respectively, adjacent the top thereof for supporting the inner casing i. Intermediate the top and bottom of each of the elements l6 and ii, there is provided an inwardly projecting lug 33 and ll] for the respective sections of the combustion box. The lugs 33 and lil are arranged to engage the bottom of the tank I! and support it in proper position. The upper ends of the housing sections are secured to each other by means of the bolts tl. The casing d is secured to the housing sections by bolts 33, one of which is provided for each section of the housing.

The door frame i9 is removably secured to the front casing element it by means of four bolts M. The plate 25 is removably secured to the frame 19, by means of two bolts t5. The Bunsen tube 36 of the burner 6 has a lug M formed on it at a point adjacent its inlet end. This lug is drilled to receive two screws 38 which are threadably received in a pair of tapped holes 5Q provided in the ledge is of the door frame.

By reason of this arrangement just described,

- bustion chamber may be readily removed through the door opening.

Furthermore, it is to be understood that the particular forms of apparatus shown and described, and the particular procedure set forth,

- are presented for purposes of explanation and illustration and that various modifications of saidapparatus and procedure can be made without departing from my invention as defined in the appended claims.

Having thus described my invention, what I claim is:

1. In a device for producing heat changes in a desired medium, a housing, an opening through a wall thereof, an open frame fitted within said opening, a burner assembly and a control valve extending through said opening, a plate mounted across the opening or said frame by partially closing same, the frame and the plate having corresponding notches for the reception of the burner and the valve, and a door acrossv the remaining portion of the frame opening.

2. In a device for producing heat changes in a desired medium, a housing having an opening through a wall thereof, an open frame fitted Within said opening, a heat exchange producing unit mounted on and supported by said frame, and closure means over said frame opening, said closure means including a door, and a fixed plate, said plate and said frame having corresponding notches for the reception of connections for the unit, the unit being removable through the frame opening after the plate is removed and the door opened.

3. An assembly of the kind described, in c0mbination, a walled enclosure having an opening therein, an open frame in said opening, a heat exchange assembly removably mounted on said frame, and having parts thereof extending through the frame opening, a plate secured to said frame, said frame and said plate defining openings through which said parts may extend and likewise defining a door opening, and a door adapted to close said door opening.
