QXRtueoM/a EDGAR A. MILLS, OF BALTEIOBE, AND RICHARD H. RICHARDS, 0F HAMILTON, MARYLAND, ASSIGNOBS OF THREE-FIFTHS TO JOHN B. WELLS, 0F BALTIMORE,

WATER-HEATER- Application filed January 18, 1915. Serial No. 2,941.

To all whom, it may concern:

Be it known that we,EneAn A. Mum and RIOHARL H. RICHARDS, citizens of the United States, residing at Baltimore and Hamilton, respectively, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Water- Heaters; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in water heaters, and consists of a certain novel construction hereinafter described and claimed.

It is an object of the present invention to provide an improved water heater which will be constructed to aiford a relatively increased area and exposure to the flame of the burner, whereby the heater will be for all purposes instantaneous in action and will heat the water to a high degree in a minimum space of time.

A further object of the present invention resides in providing an improved water heater, the construction whereofwill be simple and the cost of manufacture economical; and the same will be arranged to be detachably connected with any of the approved forms of gas or other burners found on the modern types of stoves. I

With these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claim.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views, Figure l is a plan view showingthe heater and burner 1n operative position; Fig. 2 shows a side elevation of the device shown in Fig. 1, parts being broken away; Fig. 3 is a bottom plan view,'partly in section, of a water heater constructed in accordance with the present invention. Fig. 4. is a cross sectional view taken on the line 2-2 of Fig. 3, and looking in the direction of the arrows; and Fig. 5 is a similar view taken on the line 33 of Fig. 3, and looking in the direction of the arrows.

In Figs. 1 and 2 the heater is shown in plan or in the upright position, while in Figs. 3, 4 and 5 the heater is shown inverted.

Referring more particularly to the drawmgs, the improved water heater is constructed of a casting arranged to provide an annular water chamber 1, comprised between an annular upper wall 2, disposed horizontally, and a pair of inclined walls 3 and 4, connected at their upper ends to opposite ends of the horizontal wall 2, and united at their lower ends in V relation.

The outer edge of the horizontal wall 2, as likewise the upper edge of the inclined wall 4., is arranged scalloped, as shown at 15, so as to provide a uniform wall area throughout the heater, and to increase the conducting and radiating surface thereof.

As advantageously disclosed in Figs. 1 and 3, the heater is constructed with a plurality of inwardly and radially disposed hollow projections arranged in communication with the annular channel 1, and formed by substantially triangular extensions 5 of the horizontal annular wall 2, and pairs of inclined-walls 6 and 7 united to the opposite edges of the extensions 5, and merging in'golthe annular inclined wall 3 of the channe The inclined walls 6 and 7 of each of the radially disposed projections provide therebetween ridges 8, which are encountered by the flame of the burner and separate and direct the flame to either side thereof and against the faces of the walls. The outer inclined and annular wall 4 is preferably formed, opposite each .of the inwardly disposed projections, with a bafiie plate 9, extending centrally between the walls of the projections and terminating short of the inner ends thereof, whereby to provide a zigzag or tortuous channel for the water as the same passes through the heater.

The water may be introduced through one connection 10, as shown in Figs. land 3, and passes out from the heater through a connection 11, arranged adjacent to the connection 10 and separated therefrom by a wall 12 extending between the annular walls of the channel 1.

Any suitable burner may be used, such, for instance, as the stellated burner B having radial arms B, shown in Figs. 1 and 2, but the burner not being a part of our invention will not be further described.

Patented June 22, 1915. i

To facilitate positioning and centering of the heater upon the burner, the same is preferably formed with depressions 13, as more particularly seen in Fig. l, which are adapted to be received by the framework of the burner or stove and support the heater at the desired position.

It will be understood from the foregoing description, taken in connection with the drawings, that the improved heater is constructed to provide Walls of substantially uniform width throughout, and to afiord a relatively increased surface exposure to the flame of the burner whereby the heater will be practically instantaneous in effect. The heater may be connected inany suitable manner to any approved type of stand boiler, or other circulating means, and

readily disconnected therefrom and replaced, and such heater is adapted to cooperate with any of the types of burners or stoves now in use. The circulation of the water through the heater will be in one direction through the annular channel 1,

and will be compelled by the baflles 9 to enter the radial projections successively until exhausted through the connection 11.

It is obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing from the spirit ofour invention, and therefore We do not Wish to be limited to such features expect as may required by the'claim.

side of said radial partition, the exterior of said body portion being scalloped to provide an increased heat absorbing and transmitting surface, and the interior of said body portion being provided with a series of hollow radial legs terminating at a distance from the center of said body portion so as to leave a substantially annular opening therethrough, which legs are V-shaped in cross section, being provided with downwardlyinclined side walls, and being also provided with inclined V-shaped end walls, and the bottom of said legs sloping upward toward the center of said body portion, substantially as described.

In testimony whereof, we aflix our signatures, in presence of two witnesses.
