WATER-HEATER.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed June 22,1906. Serial No. 822,842.

To ail/Z w/tom it may concern:

Be it known that 1, AUGUST GoLDFmN, a citizen of the United States, a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in l/Vater-Heaters, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions. I

My invention relates to improvements in water-heating devices, and particularly the class of such devices now quite generally advertised as instantaneous water-heaters, which are used about the house for quickly heating relatively small quantities of water, as for toilet and laundry purposes.

In this class of heaters the fuel employed is preferably gas and because of its expensive ness in most localities it is highly desirable that its heating capacity, or fuel utilized to the fullest extent.

The object of my present invention, then, is to provide a heater that will be economical in its operation; as also one that will at the same time be of simple construction.

To the accomplishment of these ends, said invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing :the figure represents a central vertical cross-section of my improved water-heating device, a part of which, however, appears in side elevation. Such heater is secured upon a hollow base A which may rest upon the floor or upon a bracket or other support to suit the convenience of the user in view of the purpose for which he desires to employ the device. The heating means here shown as consisting of an annular gas-burner B, are disposed within base A, the heated products of combustion being conducted upwardly therefrom within the walls of a cylindrical casing C.

The casing is surmounted by a cap C provided with an aperture 0 through which connection may be had with a chimney or ventilator in order to remove the spent gases. Within the casing as above described is value, be

mounted the water-containing member D to which I more especially call attention. This member Dis essentially a hollow metal structure comprising a central cylindrical portion d and a flange portion (1 that winds about such cylindrical portion. Such flange portion d, as will clearly appear from an inspection of the figure, is differently inclined in alternate )arts certain arts as d bein sub- 6 stantially horizontal in their disposition while the intermediate parts d are inclined at a greater or less angle to the horizontal. The arrangement of these differently inclined parts is such that those of successive turns of the flange that are similarly inclined are in substantially vertical alinement. Communication with the interior of structure D is had through an inlet d that preferably opers into fian e d at its lowest oint and through D I i.

an outlet d at the top of the structure. A water-supply pipe (i is connected with the former, and a water-discharge pipe (F with the latter, of these two openings. The

structure thus described, can be very easily and cheaply cast in a single piece, apertures (Z and d being afterward threaded for the reception of the ends of pipes (Z and (P respectively.

In order to confine the water, during its 8 5 .passage through the structure, to flange portion d, where as is obvious it will be in more direct contact with the heated gases arising from burner B, I provide means for separating such flange-portion from the central 9o positioned within cylindrical portion (2 of 100 the structure as not to require any other means to retain it permanently in lace. In practice I find it best to make this p. ug in the form of a cylinder, thin sheet copper or other non-corroding metal being the preferred material. Obviously such cylinder need not be water tight it will satisfactorily serve its purpose of preventing a direct upward flow of water even if it does leak.

From the foregoing description of the con- I 10 struction of my improved water-heater it y will be readily seen that the water is forced This plug is introduced to circulate through the flat walled hollow flange d for the entire length. of the structure D. It is accordingly thoroughly exposed to the heated gases that ascend by way of the winding passage formed intermediately of the turns of such flange and closed laterally by the outer casing C. The heating efl ect of these gases is considerably emphasized by the peculiar form given this passage through the disposition of the flange, alternate'parts of which, as has been stated, are diflerently inclined. Thus the horizontal portions of such passage serve to retard the flow of the gases therethrough just enough to permit the absorption by the walls of the passage of a maximum quota of heat. And while the portions of increased inclination serve to accelerate such flow the inclined parts of the flange-wall forming such. portlons at the same time act as baflle .lates in that they are interposed directly in the path of the gaseous current. A similar battle-plate effeet is, of course, afforded by the interior face of such flange-wall in connection with the ascending current of water. A high degree of heating efl'iciency is accordingly developed as a result of the double action of such inclined parts of the hollow flange.

Having thus described my invention in detail, that which I particularly point out and distinctly claim is 1. In a water-heating device, a verticallydisposed. hollow structure comprising a central cylindrical portion and a hollow flange portion winding about the same, the turns of said hollow flange portion being spaced apart and inclined upward at different angles in alternate parts, and a casing fitted around the flange portion to laterally inclose the same.

2. In a water-heating device, a verticallydisposed hollow structure comprising a central cylindrical portion and. a hollow flange portion winding about the same, the turns oi said hollow flange portion being spaced apart and inclined upward at diflerent angles in alternate parts, and similarly inclined parts of successive turns of said flange being in. substantially vertical alinement, and a casing for laterally inclosing the flange portion.

3. In a water-heating device, a vertically disposed hollow structure comprising a central cylindrical portion and a hollow flange portion winding about the same, the turns of said hollow flange portion being spaced apart and disposed bothhorizontally and at an angle in alternate parts, the inclined parts being adapted to serve as balfle-plates, and. a casing fitted around the flange portion to laterally inclose the same.

4. In a water-heating device, a vertically disposed hollow structure comprising a central cylindrical portion and a hollow flange portion winding about the same, the turns of said hollow flange portion being spaced apart and disposed both horizontally and at an angle in alternate parts, and similarly disposed parts of successive turns of said flange being in substantially vertical aliiuanent, and a casing for laterally inclosing the hinge portion.

5. In a water-heating device, a verticallydisposed. hollow structure com prising a closed central cylindrical portion and a hollow flange portion winding around. the same, the turns said hollow flange portion being spared apart and difl'erently inclined in alternate parts. and a casing titted around the flange portion to laterally inclose the same.

6. In a water-heating device, the combination with. a vertically disposed hollow structure comprising a central cylindrical portion and a hollow flange portion winding around the same, of means in said cylindrical portion separating it from the turns ol said nollow flange portion, said. flange portion being spaced apart and disposed both horizontally and at an angle in alternate parts, and a rasing for laterally inclosing the flange poi tion.

7. In a water-heating device, the combina tion of a vertically disposed hollow structure comprising a central cylindrical portion and a hollow flange portion winding around the same, the turns ol said hollow flange portion being spaced apart and disposed both horizontally and at an angle in alternate parts, and similarly disposed parts ol sueressive turns of said flange being in substantially vertical alinement; means in said .-.ylindrical portion separating it from. said. flange portion; water connections to and from the latter; and a casing laterally inclosing the whole.

8. In a waterheating device, the combii'iation of a vertically disposed hollow structure comprising a central cylindrical portion and a hollow flange portion winding around the same, the turns of said hollow flange portion being spaced apart and disposed both horizontally and at an angle in alternate parts, similarly disposed. parts of successive tn rns being in sul'istantially vertical alinement: a plug fitted within said cylindrical portion and separating it from said flange portion; water connections to and from said flange portion: a cylindrical casing litted about said flange portion so as to laterally inclose he whole structure, wl'iertby 2, flue is l'ornied intermediately of si'iceessive turns ol' said flange, such flue connnising a series ol horizontally disposed passages and alternating therewith a series of inclined passages eonneeting such horizontally disposed passages: and. l'ieating means connected with said flue.
