WATER-HEATER.

Specification of Letters Patent.

Patented Feb. 111, 11919.

Application filed August 17, 1916. Serial No. 115,380.

Be it known that I, JosEPH G. BECK- -MANN, a citizen of the United States, and

resident of St. Louis, Missouri, have 1nvente'd certain new and useful Improvements in Water-Heaters, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in water'heaters, designed primarily for domestic purposes, and my improvements are especially directed to the construction of the boiler or water heating body and its casing or shell, the object of my invention being to construct a boiler and to provide a casing therefor and arrange same to be heated by a gas or other vapor burner which will heat a maximum volume of water at a relatively high temperature in a minimum of time and without the usual pounding due to improper circulation.

With the above purposes in view, my 1nvention consists in certain novel details of the construction and arrangement of parts hereinafter fully, clearly and concisely set forthin my specification, pointed out 1n my claims and illustrated by the accompanying drawing, in which Figure 1 is an elevation of a devlce embodylng my improvements, with the door of the casing in an open positlon;

Fig, 2 1S a vertical sectional elevation of the casing or shell having the boiler and burners removed and taken at right angles to Fig. 1;

Fig. 3 is a sectional plan vlew taken on the line 33 of Fig. 1, with the door of the casing in a closed posltion; v

Fig. 4 is an enlarged fragmental sectlonal elevation illustrating the construction of the walls of the boiler; and

Fig. 5 is a sectional elevat on of the base portion of the casing, showing the means for attaching a burner to the bottom of the base.

- when the device is set up rests upon the union and thus supports said base 11.

Arislng from the upper end of the base is a flange 14 and extending upwardly beyond said flange is a number of ears 15, one only of WlllCh is shown in Fig. 2. The flange 14 1s inset from the outer periphery of the base formlng a shoulder 16, which shoulder constitutes a support for the casing or shell of the boiler.

By preference the casing comprises two sections of semi-cylindrical formation, the one section 17 arranged to rest upon the shoulder 16 of the base and be secured to, the base by means of bolts extended through openlngs formed in the section 17 and through the ears 15, the other section 18 of the casing being hinged to the base, the lowermost hinge comprising a perforated lntegral extension 19 of the base an an integral outstanding lug 20 having a pin 21, as clearly shown in Flg. l.

The reference numeral 22 designates the cap of the casing, which is provided with a flange 23 corresponding with the flange 14 of the base, except for its inversion when assembled, and with an outstanding shoulder 24 arranged to snugly 'fit the upper margins of the sections 17 and 18 of the casing. Like the base 11, the cap 22 is provided with ears 25 whereby to secure the section 17 of the casing to the cap. Formed centrally through the cap is an opening 26 through which a pipe 27 extends for connecting the upper end of the boiler 10 to a water tank or the like (not shown).

By preference I employ a shortnipple 28 (shown only by dotted lines in Fig. 1) which connects directly with the boiler 10 and extends through the opening 26 and is connected with the pipe 27 by a union 29. By reason of the union 29 and the union 8, I am enabled to facilitate the assembling of the casing elements by exerting pressure on the cap and base by saiclunions thus holding the casing elements assembled during their connection by the bolts 15 securing the one shell section to the base and the bolts connecting the said shell section with the cap.

Formed through the cap to one side of the opening 26 there is an opening 30, and surrounding the opening is an outstanding bead or collar 31 for connection with a flue (not shown) to carry of]? the unconsumed gases, vapors, or other odors arising from the casing.

Extending laterally from the cap 22 is an ear 32, constituting a portion of the hinge connection between the section 18 or door of the casing and the cap, the other portion of the said hinge connection being a lug 33, the companion of the lug 20 hereinbefore described.

In order to secure the door in a closed position, I provide the section 17 of the casing with an integral outstanding car 34' and the section 18 or door with an integral outstanding hooked element or latch 35, which in closing the door automatically rides over the ear 34 and seats thereover to lock the door, it being necessary for opening the door to release the hinged element 35 by elevating it over and from the car 34. The boiler lO is formed preferably by casting as an integral unit comprising two tubular columns 36 and 37, the respective ends of which are united by return bends 38 and 39, the columns of said bends taking the form of an elongated 0.

The inner surface, as clearly shown in Fig. 4, is undulated in order to present to the water therein a maximum of surface as well as a retarding influence. The outer surfaces of the columns, as well as the return bends of the boiler, are provided with spaced annular outstanding fins 40, certain of which, extending between the columns, are integrally united whereby to lend rigidity to the boiler as well as to constitute additional means to retard and circuitously deflect the heat units in their traverse of the casing. Each of these fins 40 constitutes a heat-absorbing body, and it is obvious that when the fins are heated they retain heat for a considerable period of time, thereby economizin-g the heating of successive quantities of water.

The fins on the vertical columns are arranged at right angles to the axes of the columns, while the fins on the return bends 38 and 39 are in radial disposition.

In. addition to the fins as means for defleeting the traverse of the hot gases or vapors, I form integrally with the sections 17 and 18 of the casing deflectors 41 and 42, each of which has an area of substantially one-half (4) the diameter of the easing, and each being provided with notches 43 to surround the columns of the boiler.

Formed integrally with the cap and extending downwardly therefrom in a vertical position and to one side of the flue opening 30 is a deflector 44, the lowermost end of which approximates the fins 40 of the boiler. Extended upwardly through the open side of the base 11 is a pair of vapor burners 45, preferably of the Bunsen type, each burner being provided with an 'earf, 46 for. connection with the bottom 12 of "the base, as clearly shown in Fig. 5. These burners are each equipped with mixers 47 and valves 48, the specific structures of which form no part of my invention. The valves are connected by means of a Y-fitting 49 to the gas service pipe 50, a portion only of which is shown in Fig. 1. It will be obvious from this showing that when the burners are ignited the flames therefrom will produce in a minimum of time a great volume of heat units which rise to the deflector 42 and contact the entire surface of the boiler or water heating body, including all of the fins 40. Meeting the deflector 42, the heat units are all deflected to one side of the casing, thereby retarding their' motion. The heat units then rise and are then shifted in their course by the deflector 41, where they again rise and are retarded by the deflector 44 before reaching the flue opening 30. In this manner there is produced a relatively long traverse for the products of combustion and hot gases through the casing, and thus cause the heat units to intimately hug the Walls of the boiler and be absorbed by the fins thereof.

The water is fed to the boiler, through the pipe 9, and by reason of the increased capacity of the column of the boiler over the pipe 9, the flow of water is much slower through said columns than through itssupply pipe 9, and by reason of the undulated surface of the heat absorbing fins, the water is heated in a rapid manner and in a considerable volume. In order that there be a minimum of escape of heat units at the joints of the casing, I have provided the lap-flanges 51, as clearly shown in Fig. 3.

It is to be observed that the upper faces of all of the fins on the columns proper are arranged horizontally, whereby to collect water of condensation and hold such water to prevent it from dropping through the casing and soiling the floor or foundation beneath the heater, thereby dispensing with a drip pan.

Having thus described my invention, what I claim as new therein and desire to secureby Letters Patent of the United States, is:

1. A boiler comprising twin columns and integral return bends uniting the columns, outstanding fins on the outer surface of the boiler, and an undulated surface within the boiler.

2. A boiler comprising twin columns, integrally united by reverse bends, a water inlet in the one bend and a water outlet in the other bend, and an undulated surface within the boiler.

3. A boiler constructed as an integral unit, comprising tubular columns, united by reverse bends, outstanding fins on said columns and reverse bends, certain of which fins between said columns are connected to lend rigidity to the boiler and to retard and deflect a heating medium and means whereby the boiler may be connected with water inlet and outlet pipes.

4. In combination with a water heating body, comprising tubular columns united by reverse bends, means for connection with water inlet and outlet pipes and heat absorbing fins, certain of which fins between said columns are connected to lend rigidity to the body and to serve as deflectors for a heating medium, a casing comprising hinged sections serving as side walls therefor, a cap and a base, a source of heat extended through said base, there being an outlet for the heat in said cap, deflectors carried by said hinged sections and notched to accommodate said columns and a deflector carried by the cap in advance of said outlet with respect to the course of the heat.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.

JOSEPH G. BEGKMANN.
