WATER-HEATER.

Specification of Letters Patent.

Patented June 18, 1907.

Application filed June 2,1906. serial No. 319,904

To all whom it may concern.-

Be it known that I, BROOKS IIAYNIE, a citizen of the United States, residing at Austin, in the county of Travis and State of Texas, have invented a new and useful Water- I-Ieater, of which the following is a specification.

This invention relates to water heaters and coolers, and has. for its principal object to provide a device of simple and compact construction by which water may be quickly heated by'the employment of a gas or other burner.

A further object of the invention is to provide a device of this class in which the water is compelled to circulate through tubes which are so arranged as to permit free expansion and contraction without danger of rupturing their connections with the headers or tube sheets.

A still further object of the invention is to provide for the secure holding of the tubes to the tube sheets without the necessity of fianging or upsetting the ends of the tubes.

A still further object of the invention is to provide a water heater having spaced headers which are connected to each other by a burner, the latter being of such construction as to permit its ready removal in case of accidental clogging of the burner orifices, or in the event of a new burner being rendered necessary.

With these and other objects in view, as I will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accomp anying drawings, and particularly pointed out in the appended claims, it being un derstood that various changes in the form, proportions, size and minor details of the structure 'may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings :Figure 1 is a longitudinal sectional elevation of a water heater constructed in accordance with the invention. Fig. 2 is a transverse sectional view of the same on the line 22 of Fig. 1. Fig. 3 is a plan view of the device with the casing and the tubes removed. Fig. 4 is a transverse sectional view through the midplane of the burner.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

In carrying out the invention, a pair of spaced headers and 11 are employed, each header being substantially trough-shaped in form and provided with marginal bolting flanges 12, to which a tube sheet 13 is secured. Each header is divided into two compartments by partitions 14;, the compartments being of unequal area, and the two smaller compartments being arranged at diagonally opposite corners of the heater, while the two larger compartments occupy the remaining diagonally opposed corners. The headers are supported on suitable feet 16, and the inner edge of each header is provided with vertically disposed lugs 18 having threaded openings for the passage of bolts 19 which serve to secure a burner 20 in position.

The burner is formed of two cast metal sheets including a base plate 21 and an upper plate 22. The base plate is substantially flat, is rectangular in form, and is provided with a continuous marginal flange 18 within, which the edge of the upper section 22 is fitted. In the opposite ends of the lower sec tion 21 are vertically disposed lugs 23 having open ended slots 24 for the passage of the securing screws 19, this construct on being such as to permit of vertical adjustment of the burner with respect to the headers, and at the same time permitting the removal of the burner as a whole in case it becomes neces sary to clean or to replace such burner.

The upper section 22 is provided with a continuous transverse channel 26, extending across the central portion of the plate, and from this channel lead a plurality of branch channels 27, arched, or of semi-circular form in cross section as indicated in Fig. 4, and the upper plate is provided with a large number of burner orifices 28, extending through the plate and communicating with the channels 27. The two burner sections are held together by a number of screws 29 which may be removed when the burner is to be taken apart for cleaning or repairs.

The lower burner plate 21 is provided with a threaded nipple which is connected to a burner 30 of any ordinary type, the burner being provided with a supply nipple 31 and including a regulating valve 32.

Thewater tubes are formed of any suitable material and being provided with downwardly curved end portions which pass through openings in the tube sheets 13, so that the tubes are free to expand and con tract to a considerable extent without danger of straining their connections with the tube sheet. In order to insure the retention of the tubes in place and prevent leakage of water, the tube sheets are provided with recessed upper faces, into which solder 41 is poured, the solder forming an upper layer on the tube sheet. and flowing around all of the tubes, so as to form a tight, Water proof oint.

The tubes are divided into three banks, one of which extends from the small compartment of the header 11 to the large compartment of the header 10 the second extends from the large compartment of the header 10 to the large compartment of the header 11, and the third extends i'rom the large compartment of the header 1] to the smaller and discharge compartment of the header 10. The header 1.1 has a nipple 42 which may be connected to a suitable source of supply, and from the smaller compartment of the header 10 leads a bib cock 43 through which the hot Water may be drawn out.

The tubes are protected by a cover plate 44 which is preferably provided with a number of perforations L5 to permit the passage of the products of combustion.

The device may, also, be employed for the purpose of cooling water and other fluids by packing ice around the tubes or by otherwise subjecting them to the influence of low temperature and forcing the liquid or fluid to be cooled through said tubes.

I claim 1. In a water heater, headers having horizontally disposed tube sheets, the upper faces of which are recessed, water tubes extending through openings in the recessed portion of each of said tube sheets, and fusible metal disposed in each of the recesses and surrounding the end portions of the tubes.

2. In a water heater, a pair of spaced headers having supporting members, a burner section detachably connected to said headers and forming a rigid connection within the same, and tubes extending from one header to the other.

3. In a water heater, the combination with a pair of spaced headers, of a burner forming a spacing and connecting means between the headers, and tubes connecting the headers and extending over the burner.

4. In a water heater, a pair of spaced headers, a burner detachably connected to the headers and serving as a connecting means between the headers, and tubes connecting the headers and arranged above the burner.

5. In a water heater, a pair of headers, each comprising a substantially trough shaped lower section having a dividing partition, and an upper tube sheet detachably connected to the lower section, supporting feet upon the headers, a burner detachably connected to the two headers and serving as a rigid connecting means between them, and water tubes extending between the tube sheets and arranged above the burner.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

BROOKS HAYNIE.
