WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 451,624, dated May 5, 1891.

Application filed August 19, 1889. Serial No. 321,204. (No model.)

To all 1071/0112, it may concern:

Be it known that 1, OSCAR M. SHANNON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in ater-Heaters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has for its object to provide an improved construction in water-heaters ment to range-boilers and similar vessels. As illustrated, it is adapted to be used either independently or in conjunction with a range having a water-back.

Figure 1 is an external view of the device in side elevation connected with a range or kitchen-boiler and having a gas-burner in place beneath it for supplying the heat. Fig. 2 is a central vertical section of the boiler and water-heater. Fig. 3 is a top or plan view of the interior shell of the water-heater.

A represents a range-boiler, of which a is the bottom plate, having the usual interiorlythreaded bushing a secured in the middle of it. A is the usual bifurcated standard supporting the boiler.

B is the water-heater of my improved construction. This heater comprises a top plate B, a bottom plate B and an interior shell or partition B The forms of these several parts are by preference as shown-that is to say, the top plate is an inverted cone or cup, the bottom plate flat, and the interior shell B conical. The bottom plate B is shown secured at its edge to the margin of the top plate B, so as to make a water-tight joint therewith, and the top plate is provided with a boss I) interiorly threaded to receive a nipple O, which may be also screwed into the bushing a of the boiler. The interior cone or shell B is smaller than the top plate B to afford a considerable space between them forming a water-passage, and is provided with a central pipe b,which rises through the passage in the nipple C, said pipe being small enough to afford a passage around the tube and within said nipple for water from the boiler to the heater. Communication is provided between the exterior and the interior of the shell 13 at the bottom thereof, which may be desirably done by means of notches or holes 19 forming openings in the lower margin of the said shell, but which may obviously be otherwise provided by supporting the shell at a distance from the bottom plate 13 The tube 1) rises within the boiler A to any desired distance, and preferably to, a height on a level with or above the entrancepipe now provided in such boilers as a connection for the hot-water pipe leading from the range water-back.

To facilitate thtarattachment of the heater B directly beneath a boiler in position on its standard, the pipe I) 1nay,if desired,be made in two or more parts, which may be slipped together, one over the other, as indicated, or connected in any suitable way.

As above described, the heater Bis adapted for the heating of the water within the boiler A by the application of any suitable gas or other burner beneath the bottom plate B The burner will operate more especially to heat the water within the cone B and as said water is heated it will rise through the pipe I), while cold water from the bottom of the boiler A will find admission to the said cone through the nipple C and around the pipe Z), passing down the outside of the cone l3 and inwardly to the interior thereof beneath the lower edge of the latter or through the notches b To adapt the heater B for connection with the water-back of a range or for drainage, an interiorly-threaded opening 19 is provided at or near the bottom of the heater, which in the illustration is connected by a branch D with the range-pipe E, but which may obviously take a faucet or connect by the usual valved drainage-pipe with the sewer;

The construction of the heater B and its directconnection with the boilerin the position directly beneath the latter, as shown, afford a very active circulation of water from one to the other, greatly simplifying the work of attachment and prevent loss of heat by radiation, such as occurs in the use of an exposed carryingpipe for the heated water. The top plate B of the heater will usuallybe cast, and the bottom plate B of sheet metal,

the two being connected by turning the margin of the bottom plate ll over a horizontall v projecting marginal llange 1/ on the lower edge of said top plate 13'.

As a means of more certainlycentering the interior shell or cone B within the outer shell of the heater ]3, the top plate B is shown provided with lugs b, which regulate the lateral space between the shells. If desired, the shell B which may be of sheet metal, as tin, zinc, or galvanized iron, may be soldered to these lugs Zr before the connection of the bottom plate B to the top plate 15.

Manifest] y various modifications may be made in the details of construction without departure from the spirit of my invention, and I do notwish to be restricted to the exact construction shown.

I claim as my invention 1. The water-heating apparatus described for attachment to range-boilers having central openings in their bottom plates, said up paratus consisting of an inverted-cup-sl1aped top plate provided with a threaded opening in the top for connection to the boiler, a bottom plate secured to the top plate, an interior shell provided with an opening or openings at its lower part and adapted to afford a water-passage exterior to itself extending from the top opening of the top plate to said lower opening or openings of the shell, and a tube leading from the upper part of the interior of said shell through the upper open ing of the top plate and adapted to extend above the bottom plate of the boiler to which the apparatus is to be secured, substantially as described.

2. As an article of manufacture, the Waterheating apparatus described for attachment to range-boilers having central openings in their bottom plates, said apparatus consisting of an inverted-cup-shaped top plate provided with a threaded opening in its top for connection with the boiler and with a lowerside opening, a bottom plate secured to the top plate, an interior shell separated by a space from the top plate and having a passage or passages at its lower part, and a tube leading from the upper part of the interior of said shell through the upper opening of the top plate and adapted to extend above the bottom plate of the boiler to which the apparatus is to be secured, substantially as described.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.
