WATER-HEATER.

SPECIFICATION forming part of Letters Patent N 0. 714,354, dated November 25, 1902.

Application filed March 31, 1902. Serial No. 100,696. (No model.)

Toall whom it may concern.-

Be it known that I, HOMER ANDERSON, a citizen of the United States, and a resident of Peekski11,in the county of WVestchester and State of New York, have invented certairi new and useful Improvements in Water-Heaters, of which the following is a specification.

This invention relates to waterheaters Whether for the purpose of obtaining hot wato tor for washing or bathing, for heating buildings, or any other'purposes requiring hot water. It may also be used forproducing steam. It is herein shown as applied to a gas waterheater; but it is not by any means limited to such purpose.

The objects of the invention are to combine in a heater means for obtaining the largest possible area of heating-surface in proportion to the quantity of water carried in the heater,

.20 for applying the heat in quantity and in the most efficient manner to obtain quick results, and for obtaining a uniform distribution of heataround the heating-surfaces. These objects are attained by the means set forth in 2 5 the specification and the drawings, forming a part thereof, that accompany it.

Figure l is a view of a gas water-heater,

, shown in elevation, with the jacketing partly removed, disclosing the features of my invention. Fig. 2 is a plan of one-half of the bottom and the gas-burner. Fig. 3 is a crossseotion of a heater-section return-bend. Fig. 4 represents a heater-section with one bend and parts of the central hubs broken away.

Fig. 5 shows a cross-section of a flat oval return-bend. Fig. 6 represents a portion of a water-section bend. Fig. 7 is the plan of the sections shown in Figs. 1, 4, and 12 and will also apply to Fig. 10. Fig. 8 shows the crosssection of a bend through line y, Fig. 7. Fig. 9 represents a portion of a section-bend. Fig. 10 represents a section, as in Fig. 4, but having bonds with a rectangular cross-section.

. Fig. 11 is a cross-sectional view through line 1 ,Fig. 10. Fig. 12 represents a section made with close return-bends and Fig. 13 is a crosssection through line y, Fig. 12.

A particular feature of this invention is the heater-section a, Figs. 1, 4, 7, 10, 12, which I can best describe as consisting of a number (eight are here shown) of return-bends standing vertically and radially from central hubs Z) Z), the upper outlet of the bends united to one hub b and the lower outlets of the bends united to the lower hub Z). For extensive manufacture it would not be desirable to make these sections actually 01E hubs and bonds on account of the expense and the number of joints that would enter into such a construction, so I make the sections of cast metal, of iron, brass, copper, aluminium, or whatever may be suitable, and what I shall call the hubs and return-bends will be understood to be preferably one integral casta 6s The form of the return-bends may be'varied to suit conditions under which the sections are to be used. The section shown in Fig. 1 is revealed in plan in Fig. 7, showing it to comprise eight bends a,having cross-sections, as shown in Fig. 8, which is taken through line 1 of Fig. 7. A flat oval cross-section, as shown in Fig. 5, and a vertical elliptical crosssection, as shown in Fig. 3, have advantages for certain uses. Instead of the bends opening in the form of an acute angle, as in Fig.

4, they may be parallel open bends, as in Fig.

6 or as in Fig. 9, in which the bend is shown to have a square cross-section. In Fig. 10 still another form of bend is shown having a cross-section as shown in Fig. 11.

In Fig. 12 the section is represented as made with close return-bends having a crosssection as in Fig. 13. The course of the water through this section is represented by the arrows n, and it is the same through all the sections shown, the water entering one hub, passing around the several bends, and passing out of the opposite hub, the water distributing itself in its flow practically equally 9o threaded nipples. As many sections may be joined to make a heater as circumstances may require.

In Fig. 1 for the purposes of a gas waterheater three sections are shown supported by the water-pipe o c. A bottom flange 6, having hubs 7 and 8, is secured to the waterpipe. This bottom is perforated, as shown in Fig. 2, and supports a base 5 and also the burner df. Upon this base the jacket 1 2 3 4: is sustained, and a top 10, with a pipe-outlet 11, surmounts the jacket. This base, jacketing, and top are features common to other heaters.

The gas-burner dfis supplied in the usual manner through a pipe 6. This burner is adapted to the form of the heater-section, having branches fin number equal to the retu rn-bends in the water-section,which have an inclination from a horizontal plane corresponding with that of the bend of the section, with the object of throwing the burner-flame as nearly as practicable at a right angle to the surface of the sections. This secures an even supply of flame beneath each bend of the first section. The burner is shown as supported by legs 9, resting on the hub 8.

In order to increase the volume of the heating medium, I place a second burner h between the first and second sections and supply it from the body of the lower burner through stand-pipes g g, the lower burner and its supply being adapted for this additional requirement of gas. To still further augment the heating medium and to insure a volume of heat about the hubs of the sections, I add still a third burner Z within the space made by the opening of the returnbends in the second water section. This burner also gets its gas-supply from the lower burner. With the two large burners h and df below the third burner it is evident there would be little oxygen left in the air ascending through the heater to support combustion at the burner Z. I therefore place a freshair-supply pipe m in such position that a strong draft will be created through it and fresh air will be injected by it right over the burner Z, which will prevent its being extinguished. A like supply of air may be conducted to the middle burner n if found necessary. The burner Z is supplied with gas from the lower burner through the pipe 2'.

A hole 16 through the jacketing is provided with a closure that may be easily opened, and through this hole the burners may be ignited, the burner Z first, when its flame will ignite the gas rising from the burner 7t and that in turn igniting the gas arising from the lower burner. It will thus be seen that if desirable I may place a burner or other adaptable heating medium contiguous to each water-section, either between the sections or within the bends of the sections, or both.

In order to prevent the products of combustion being drawn to one side of the heater by the draft through the pipe-outlet 11, I place a baflle-plate 25 within the top of the jacketing with an opening only in the center. This will tend to draw the heated air about the center of the water-sections, while the form of the water-sections will have a tendency to deflect the hot air away from their centers.

In the supply of gas to more than one burner, as herein described, I do not wish to be limited to the manner shown of supplying each burner from a single one, as a reservoir. It is plainly practicable to give each burner an independent supply and provide that one or more burners may be lighted, according to the requirements for hot water. It will be plain also that the gas-burners shown may be displaced for naphtha or other fluid burners, and the sections are well adapted for the employment of electric heaters, and I desire that my claims shall include such means of heating.

I claim- 1. In a water-heating device a heating-section composed of hollow hubs and a series of return-bends radiating from said hubs and constituting communicating tubes between the hubs, whereby the water flows freely from one hub to the other through said returnbends, substantially as described.

2. The combination substantially as herein shown of a heater composed of sections consisting of open return-bends united radially to central hubs in the manner described, a burner under the bottom section adapted to project its flames at a right angle to the heating-surface of the section, a burner between the first and second sections supplied with gas from the lower burner, a burner, likewise supplied with gas from the lower burner, within the bends of the second section, and a fresh-air-supply pipe to the top burner.

3. The combination substantially as herein shown, of a heater composed of sections consisting of open return-bends united radially to central hubs in the manner set forth, a burner under the bottom section adapted to project its flames at a right angle to the heating-surface of the section, a burner between the first and second sections supplied with gas from the lower burner, a burner within the bends of the second section likewise supplied with gas from the lower burner, a freshair inlet contiguous to the top burner, and an opening in the jacketing to facilitate the lighting of the top burner.

4. The combination substantially as herein shown of a heater composed of sections consisting of open return-bends united radially to central hubs in the manner set forth, a burner under the bottom section adapted to project its flames at right angles to the heating-surface of the sections, a burner between the first and second sections supplied with gas from the lower burner, a burner between the bends of the second section as shown like- ICC wise supplied with gas from the lower burner, chester and State of New York, thii 28th day a freshair inlet contiguous to the top burner,

an opening in the jacket of the heater to fa,-

cilitate the lighting of the top burner, and a,

5 tbaffle-plate with a central opening above the top section.
