PATENT OFFICE.

GA-S WATER HEATER.

Application filed January-9, 1924; Serial No. 685,272.

To all whom it may concern:

Be it known that I, ISAAC GORDON, a citizen of the United States, and a resident of the city and State of New York, have invented certain new and useful Improve ments in a Gas Water Heater, of which the following is a full, clear, tion.

The invention relates to a Bunsen style gas water heater and cooker, which is adapted to operate with a single or double and exact descriplead burner in any type of water heater,'or

- thereby not only adding to theusefulness I that it really assists in applying the heat'to of a range and saving thespace and expenseof a separate'water heater, but also greatly reducing the consumption of gas.

Another object of the invention i'sto provide awater heater of this character so 'con structed that it in no way interferes with the direct application of the burner heat to. On the contrary the,

the cooking vessel. construction of the water heater 1S-S11Cl1 the cooking vessel and ':reduces' the loss of heat by radiation.

Still other objects of the invention are toprovide. a burnerand water heater so constructed that the heat of the yburner is in tensified against the water pipesor other" style of water heater; so constructedgthat the diffusing .of' the heat from the water heatin member will be prevented;- so'con- 'structed' as to eliminate-the escape of car-' bon monoxide or other poisonous gases andleadfurnishes gas to' .the lower-and upper also so constructed that the cooking, baking and heating may all be accomplished in amost sanitary manner.

Further objects of my invention will be apparent from the following detailed description when taken in connection with the The jets from 4 need only be employed when accompanying drawings; in which,

Figure l is a front elevation of the casing detached from the range.

. Figure 6 is a perspective of a portion of a range with my water heater mounted in place therein; and

Figure 7 is a vertical sectional view of modified form of water heater.-

. Referring to the drawings more in detail, particularly to Figure 5, numeral 1 indicates a single lead burner having an annular flange member at its lower end; the flange member being provided-withtwo rows of holes, referred tocby numeral 2, and arrangedto direct the flame vertically against two coils of a wat'e'r heater-disposed directly overthe holes. Theupper portion of the burner is provided withfa-single circular series of holes 3 adapted toiproject the flame,-at an angle 'ofpsubstantially 45 130 the verticahagain-st the water heater. Also atthe top of the burner are two cross-arms having holes 4 adapted, to project the-flame vertically;v The burner is linedwith 'asbes tos between theupper and lower'se'rie's {of holes, as indicated-by numeral '5. a The burner which I have just described, and which is-illustratediin Figure 5,;has1'only a single leadfi, and hence it is necessary fto employ-the entire burner whether; or not the full amount of heat is necessary.

In Figure 41 haVeilI'ustrated a double lead burner referrefd to generally by numeral 7. ;The: construction; is .identical,;;ex- 'cept'that there are .two leads, 8, 8; and one of these leads furnishes gas solely. to] v the holes in the cross-arms 4, while .the othe r' cooking alone is desired, or when fast cooking and water heating .is-desire'dghfor the jets from {chef-holes 2 and 3:x'vill besufiicient for ordinary purposes.

A- water coil, indicatedgenerally by numeral 9,- is mounted over either type? of burner.

In Figures 2 I have shown the coil mounted over the double lead burner 7, such as illustrated in Figure t. The particular coil employed is of very material importance. By reference to Figure 2 it will be seen that the bottom of the coil is double; as indicated by numeral 10, and that one of these coils is arranged directly over each of the two circular rows of holes 2. The heating capacity is thus greatly increased for there are two lower coils and there is a circular row of jets applied directly to each of the coils. The ramainder of the water heater consists of single coils, and all of the coils are slightly spaced to permit the flames to pass between the coils. At the top of the wat'rr heater each succeeding coil is of less diameter than the one below it, as clearly shown in Figure 2, and by this arrangement the heat from the burner is prevented from being difl'used, and also the flames from the upper holes 3 are caused to act more directly on the coil; and to assist in this direct action of the flames on the coil, the holes 3 are arranged at 45 to the vertical.

ater is carried from the tank (not shown) to the bottom of the coil by the pipe 11, and the pipe 12 carries the heated water from the top of the coil to the tank.

The burner and water heater are placed in a metallic cylindrical casing 13, provided with a door 14:; and the interior of the cas ing is lined with asbestos, as indicated by numeral 15. To prevent any escape of carbon gases, vent holes 16 are provided in the top of the casing, and these may be connected to the range flues. The casing 13 is provided with hangers 17, and the casing with the burner and water heater arranged in it is bolted to the inside part of the. range, up against the cooking top thereof by means of the hangers.

In Figure 7 I have shown a modified form of water heater. This form of water heater is indicated by numeral 18, and it will be seen that it is of a general cylindrical shape with the upper portion thereof curved inwardly, so that it is of substantially the same shape as the coil water heater. The walls of the heater 18 are hollow, as indicated by numeral 19, and a pipe 20 supplies the water to the bottom of the heater, while pipe 21 carries off the heated water. It will be understood that the water heater 18 may be substituted for the coil water heater, if desired.

It is believed that the construction and operation of the device will be clearly under stood from the foregoing description. The particular shape of the coil not only results in a very rapid heating of the water but also prevents the diffusing of the heat; and by the use of an asbestos lining for the burner and easing, there is very little less of heat by radiat n f om the inter or of the burner or the exterior of the casing. Further, the construction of the water heater is such that it does not in any way interfere with the direct application of the flames from the holes 4 to the cooking utensil. Further, by the use of a double lead burner there is a saving of fuel, for it is only IliCQS- sary to use the jets 4 when there is cooking alone to be done, or the jets 2 and 3 only when there is to be ordinary cooking and water heating; and jets 2, 3, and a. only when there is to be rapid cooking and water heating.

The water heater may be in the form of a coil, or in any other form, such as the" cylindrical member 13 having its upper portion curved inwardly, as illustrated in Fig. 7; and it is therefore to be understood that the term coil us'fd in the claims is in tended to cover such an equivalent structure v as that illustrated in Fig. 7.

The present invention constitutes an improvement on my invention in water heaters disclosed in patent sit-1,474,931, granted to me November 20, 1923.

In accordance with the patent statutes, I iave described what I now believe to be the best embodiment of the invention, but I do not wish to be understood thereby as limiting the scope of the invention, as many changes and modifications may be made without departing from the spirit of the invention; all such I aim to include in the scope of the appended claims:
