LEE I-I. WILLIAMS, OF INDIANAPOLIS, INDIANA, ASSIGNOR OF ONE-HALF TO THE HCELVVAINE-RIOHARDS COMPANY, OF SAME PLACE.

WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 597,927, dated January 25, 1898.

Application filed June 16, 1897. Serial No. 641,050. (No model.)

To ctZZ whom it may concern:

Be it known that I, LEE H. NVILLIAMS, of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Water-Heater; and l do hereby declare that the following is a full, clear, and exact description thereof, reference beinghad to the accompanying drawings, in which like numerals refer to like parts.

My invention relates to water-heaters employed chiefly in houses for domestic use.

The object of the invention is to secure a heater that is simple of construction, strong and durable, economical, and more efficient than similar devices heretofore made.

One feature of the invention consists in making the water-chamber of the heater of one piece by casting the same, so as to bring about increased strength and diminution in size and an increase in the comparative heating efficiency.

Another feature is to render it possible to remove incrustations from the inner surface of the water-chamber without removing the heater from the boiler and to otherwise make such operation simple and easy.

Another feature is to construct the fueloutlet so that back drafts will not blow out the gas or re.

There are other features of invention which will be understood from the description and claims following and the accompanying drawings.

In the drawings, Figure l is a vertical section of the hot-water boiler and heater with the necessary pipes and appurtenances thereto attached. Fig. 2 is a section on the line 2 2 of Fig. l. Fig. 3 is a bottom view of the heater on the line 3 3 of Fig. l.

In det-ail, 1 is a suitable stand for the hotwater tank or boiler 2. 3 is a suitable inletpipe for the cold water, While t is an outletpipe for the hot water from said tank or boiler. 5 is an outlet-pipe from the tank or boiler leading to the heater, and 6 is a pipe leading from the heater to the boiler. The hea-ter consists of a hot-water chamber 7, with an opening at its upper end which is closed by the disk or plate 8. The waterchamber 7 of the heater is preferably cast in substantially the form shown. In forming or casting the same a tapering extension 13 eX- tends centrally from the lower end partially through the chamber forming the heatingchamber 9. At the lower end of this heatingchamber the gas-burner l0 or any suitable burner is located,so that the flame therefrom will strike the water-chamber at its lower end and extend up almost to the chimney or hotair pipe l2, which leads from the upper end of the extension 13, as shown. A gas-pipe 1l supplies the burner 10. The burner is prevented from extending so far up that the flames therefrom will not come in contact with the lower part of the water-chamber by means of the arms 24, secured to a collar that is fastened on the gas-pipe just below the burner. The length of the arms is such that they come in contact with the lower part of the chamber and prevent the burner from being placed too high.

The extension 13, that forms the heatingchamber 9, is at its lower end some distance from the outer Wall of the chamber '7. At least sufficient room is thereby provided for the entrance of the pipe 5, leading from the boiler,

and for the holes closed by the nuts or plugs '14. Preferably three of these openings are provided besides the one through which the pipe 3 enters.

The outside wall of the water-chamber 7 extends vertically for some distance and then is contracted, so that the volume of water surrounding the upper part of the inner wall lis greater than that which surrounds the lower part or base, because at the upper part the heat is greater than it is below. By this construction, therefore, the volume of water is in proportion to the extent of heat that is applied to it. Around the upper part of the opening of the water-chamber 7 I provide an annular horizontal flange l5, to which the closing-plate 8 is bolted securely. This plate has a central opening in it for the pipe l2 and a vertical annular collar 16 of greater diameter than the pipe l2. Between this collar and the pipe suitable packing, asbestos wick being preferable, is placed. To hold said packing in place, a second or upper plate 17 is bolted to the lower plate 8. Said upper plate has a downwardly-extending annular collar 20 large enough to pass over the annular col- IOC) vthat passes through the pipe l2.

lar 16 on the lower plate, and an annular recess in said upper plate adjacent to said collar is made to snugly receive the upper end of the collar 16 on the lower plate 8. By screwing down said plate tightly the packing is greatly compressed around the pipe 1 2, so as to prevent any escape of the heated water.

Detachably secured about the upper plate 17 there is a conical or tapering pipe 2l, leading to the outlet-pipe 22 for the purpose of conveying the hot air from the burner below The pipe 12 extends into the tapering outlet-pipe 21 about half-way. The plate 17 is provided with a series of holes 23, through which air can pass into the pipe 21 and outlet-pipe 22; but the main function of said opening 23 is to serve as an outlet for any back draft that may be caused by any means down through the pipe 22 and conical pipe 2].. Such back draft, by escape through the openings 23, it is obvious will not blow out the fire below in lthe burner 10. This is of value because a sudden back draft is liable to blow out the 'flame and leave the gas escaping very rapidly, whereby an explosion may result.

In this description it will be observed that the incrustations that may be formed on the inner surface of the water-chamber can be removed without removing said water-chamber or separating it from the boiler. This is done by removing the plate 8 after loosening the bolts that secure it to the water-chamber. Then through the opening in the upper end of the water-chambera chisel or other implement can be introduced for loosening the incrustations. The particles of material thus loosened are removed through any of the holes in the bottom of the water-chamber after removing the plugs 14, that close them. In fact the hand can be introduced in the opening at the upper end of the water-chamber. This mode of cleaning the water-chamber is a very simple and effective one, without disturbing the water-tight joints of the connection between the water-chamber and the boiler.

Vhat I claim as my invention, and desire to secure by-Letters Patent, is

l. A water-heating apparatus including a water-chambercontracted and open at its upper end with an annular flange surrounding such opening and with the central portion of its bottom extending upward and tapering to form a heating-chamber and holes in the bottom of the water-chamber, a plate for closing the opening at the upper end bolted to said annular flange, and detachable plugs for closing the holes in the lower end of such waterchamber, substantially as set forth.

2. In a water-heating apparatus, the combination with a suitable burner, of a water chamber with a central upward extension from the bottom surrounding said burner, an outlet-pipe leading upward from the upper end of said extension for the escape of the gases from the burner, a pair of plates for closing the upper opening in said water-chamber and surrounding said pipe, the lower of said plates being secured by bolts to lsaid water-chamber and having an annular collar on its upper side surrounding said outlet-pipe, packing filled in said annular collar around said pipe, and the upper one of said plates being secured to the lower one by bolts and having a downwardly extending annular flange that snugly surrounds the annular flange from the plate below, substantially as set forth. f

3. In a water-heating apparatus, the combination with a burner, of a water-chamber with a passage centrally upward through the LEE H. WILLIAMS.
