HENRY R. CHURCHIELL, 0F BUFFELLO, NEW YORK.

WATER-HEATER.

To all whom it may concern:

Be it known that LHENRY R. Crruncmnn, a citizen of the United States residing at Buffalo, in the county of Erie and State of New York have invented a. certain new and useful Improvement in ll 'ater-Iileaters. of which the following is a specification.

This invention relates to an improved water heater and the object is to produce a comparatively cheap and economical device with which water may be rapidly heated.

The invention also relates to certain details of construction, which will be hereinafter described and claimed reference being had to the accompanying iflrawings in which Figure 1 is a central vertical section through my improved water heater and a storage tank of ordinary kind to which it is attached, the heat detlectors within the fire tube of-the heaterb'ei ng shown in elevation. Fig. 2 is an enlarged plan VlQW of my improved water heater with the upper-ring or stove pipe support removed. Fig. 3 is an enlarged transverse section through my improved water heater on line a a, Fig. 1. Fig. 4 is an enlarged detached plan view of the burner of my improved Water heater. Fig. 5 an eulareed detached plan View of the upper ring or store pipe support. Fig. 6 an. enlarged detached side view of one of the cross like heat deflectors. Fig. "7 is a section on line Z) Z), l ig. (i. Fig. 8 is a central vertical section through one of the tubular heat deflectors on line 0 c. Fig. 9. Fig. 9 is a transverse section on line at I]. Fig. 8. Fig. 10 is an enlarged fragmentary central section through. the burner. Fig. 11 is an inn larged fragmentary central section through the nozzle of the burner.

In referring to the water heater in detail like numerals designate like parts.

In the accompanying drawings a heater or" the improved construction is shown connected to a Water tank 1, of conventional type which is mounted on a base 2. A pipe 3 which is connected to a source of water supply serves as the cold water inlet pins to the water tank. The hot water outnet pipe 4 is connected to the top of the tank and extends to any "desired location.

The heating device has two vertical tubes 5 and 6 which are arranged concentrically with each other. These tubes differ in diameter and the smaller tube 5 is located. within thelarger'tuhe 6 and is sutlicientlv Specification of Letters Patent. application filed July 17, 1906.

Patented Nov, 3%) Serial No. 443,957,

smaller than the larger tube to leave an anuular space 7 between the tubes. The tubes are joined at their upper and lower ends to entirely close the upper and lower ends of the annular space 7 by rings 8 and 9. These rings are fitted in place between the tubes and are secured to the tube surface by welding or other suitable means, preferably by the autog'enous or gas weldingmethod. .Pipe connections 10, 11 and 1.2 are also preferably welded to the surface of the outer tube 6 that the tubes with their connecting parts practically constitute an integral inseparate element which can never leak.

A burner 13 is located centrally beneath the lower end of the inner tube 5 and extends upward from an air mixer which consists of a bell-shaped or flaring enlargement 1+1 dependingbelow the burner and having arms which radiate from a. central boss 15; and connectf'to the lower end of the enlargement. A pipe 16 which is exteriorly screw threaded has its lower end adjustably screwed into a base or pedestal 17 and its upper end adjustably screwed into an openin in a l coupling 18 which is connected y piping 19 to a source of gas supply. A short pipe 20 has its ends screwed into the boss 15 of the bell shaped enlargement and the T coupling 18. An air regulating disk 21 is adjustably mounted on the pipe 20 and is adjustable in a vertical direction to regulate the volume of air admitted into the bell-shaped ei'ilargement 14. A nozzle is fitted in the upper end of the pipe 20. A

cup 23 arranged around the hurner servesto catch the drip caused by condensation. This cup is prefe'ably made integral with the burner.

*Within the inner tube 5 which constitutes the fire tube is arranged a series of defleeting elements which serve to muffle the noise of the burner and to deflect the heat against the surface of the tube, causing" the flame, the heat and the products of combustion to follow a circuitous path in passing through the tube and thereby more ellicieutly heating tl!e't11l).. These elementsconsists oi. skeleton elements having radial arms and tubu- .lar elements. The lower element has a series of arms 24 preferably tour in number which radiate from a common central body 25 and a stern Edwhieh screws into a central opening in the. perforated top portion of the burner. This element is arranged horizon tally with the arms extending horizontally.

Above the lower element is located a series of similar elements 27 preferably six in number which are arranged in vertical and horizontal positions as shown in Fig..1.' The arms of those arranged in vertical position extend diagonally and the arms of those arranged in horizontal position extend horizontally and serve to interrupt the flow of the flame and to deflect it into contact with the inner tube. The arms of the vertical elementsact as supports for the horizontal elements and also serve to separate the horizontally arranged elements and provide passages. for the heated gases and. products of combustion. Above the radial arm elements are arranged a series of tubular elements in a vertical row. Each of these elements consist of a tube 28 having a series of slots 29 for the passa e of the products of combustion and a ange 30 which extends outwardly from about midway of the tube.

' The ends of the tubular elements are closed and the slots 29 are cut in the circular side Walls of the elements in two circular rows, one being arranged above the flange 30.

and the other below the'flange so that the products of combustion pass into the tubular element through the lower series of slots and out through the upper series ofslots and thus follow a circuitous path' and are deflected against the inner tube to rapidly heat the same.

A top 31 isarranged over the upper ends of the tubes and has an overhanging flange 32 and a central upwardly extending tubular portion 33 to which the lower end of a chimney pi e 34 is attached.

The tubu ar elements are supported by a depending rod 35 which has an eye, at-its upper end through which a transverse bar 36 passes. This bar is supported in V-shaped depressions in lugs 37 forged'on opposite sides of the interior of the upwardly extending tubular portion 33 of the top 31.

The rod sses through openings 38 in the tubular e ements and a nut 39 screwed-upon the lower end of the rod retains the tubular elements in place therein. The to 31 also has a short depending annular ange 4.0 which fits within the upper end of the fire tube 5 and serves to secure the top in place.

The outlet pipe 41 for hot water is attached to the upper pipe connection 10 and is connected'at its other end to the pipe 4, and the inlet pipe 42 for cold water leads from the bottom of the storage tank its the lower pipe connection 11 on the heater see Fig. 1. 4

A blow off faucet 43 for cleaning purposes is attached to the connection 12 and the gas supply pipe 19 has the usual valve 44.

The operation of the heater will be easily understood from the foregoing description and drawings. The heated gases and the products of combustion first impinge against the surfaces of the skeleton elements and are separated and deflected in various directions. Upon reaching the tubular elements located in the upper portion of the tube, the gases which have cooled somewhat are collected in the tube and th n forced outward in a series of streams agai! it the inner surface of the tube and heating the same. By this means the tube is heated uniformly throughout, as the tubular elements offer more of an obstruction to the passageof the gases than the skeleton elements and enable a large percentage of theremaining heat units of the gases to be convectcd to the wall of the tube.

I claim- I 1. in a water heater, two concentric tubes separated sufficiently to leave an annular water space and the inner tube being open throughout to constitute the fire tube, a burner beneath the tubes and skeleton deflecting elements within the inner tube, each having a central body and radial arms extending from said body and located at equal distances apart, one of said deflecting elcments being horizontal with its arms extendmg horizontally, and another being vertical with its arms extending diagonally and serving as supports for the horizontally arranged deflecting element.

2. In a water heater, two concentr c: tubes separated sufliciently to leave an annular water space, a burner beneath the tubes, a series of skeleton deflecting elements within the inner tube having a central body and radial arms, some of said skeleton elements being arranged horizontally with their arms extending horizontally and others being arranged vertically with their arms extending diagonally and servin as supports for the horizontally arrange deflecting elements and tubular deflecting elements within the inner tube above the skeleton deflcdting elements.

3. In a water heater, two concentric tubes separated sufficiently to leave an annular water space, a burner beneath the tubes and a series of skeleton deflecting elements within the inner tube having a central body and radial arms, some of saiil skeleton elements being arranged horizontally witli their ur ns extending horizontally and others being arranged vertically with their arms extending diagtmally and serving as supports for the horizontally arranged deflecting elements.

4. In a water heater, two concentric tubes separated sufficiently to leave an annular water ace, a burner beneath the tubes, a series 0 skeleton deflecting elements within the inner tube having a central body and radial arms, some of said skeleton elements being arranged horizontally with their arms extending horizontally and others being arranged vertically with their arms extending diagonallv and serving as'sunnforts for the horizontally arranged deflecting elements! and a tubular deflecting element arranged vertically within the inner tube and smaller in'circumference than said inner tube, said tubular deflecting element being located above the skeleton deflecting elements and having closed ends and an intermediate annular outer flange which extends in pr0xilnity t0 the inner surface of the wall (if the inner tube and being provided \Villl sale 10 openings in the Walls above and below the ange.
