HUGH ROBERT BYNUM, 0F CLARKSDALE, MISSISSIPPI.

WATER-HEATER.

Application filed April 13, 1917.

To all whom it may concern:

Be it known that I, HUGH ROBERT BYNUM, a citizen of the United States, residing at Clarksdale, Coahoma county, and State of Mississippi, have invented and discovered certain new and useful Improvements in l'Vater-Heaters, of which the following is a specification.

My said invention relates to water heaters and consists'in the combinations and arrangements of elements hereinafter described and particularly set forth in the accompanying claims.

The object of the invention is to provide a heater for use in supplying heat for buildings, or for any other purpose for which it may be found appropriate, in which the heating apparatus is of comparatively simple and inexpensive construction, capable of being quickly and easily installed, and in which the maximum of the heat units from the fuel will be utilized in heating the water, which is designed to serve as the principal heating medium, allas hereinafter described and claimed.

The invention is shown by way of illustration in the accompanying drawings, where- 1n- Figure 1 is a perspective view of the water heater,

Fig. 2 a longitudinal sectional view taken on the dotted line 2-2 in Fig. 5,

Fig. 3 a transverse sectional view taken on the line 3-3 of Fig. 2,

Fig. 1 a similar view taken on the line 4-4 of Fig. 2, and

Fig. 5 a horizontal sectional view taken on the line 5-5 of Fig. 2.

Referring to the construction in detail, the heater consists of a suitable frame comprising arch pieces or

yokes

6 and 7, located at either end of the frame and supporting the tank or vessel comprising an inner section 8 and an outer section 9, leaving between them a water space or chamber 10 substantially surrounding said section 8, and which constitutes the initial or primary heater of the apparatus. A suitable incasement or housing 11 surrounds the outer wall 9 of the heater and is formed integral, or continuously united with the rear wall thereof, and, in like manner, with the bottom wall 12 that provides a base for the heater.

The front portion of the casing 11 1s formed with a flange 13, and the sections 8 and 9 project beyond and have a frame or Specification of Letters Patent.

Serial No. 161,821.

yoke 14: between them forming the front a body portion 17 (see Fig. 2), supported by the inset part 18 of the front frame-piece 7, and the door part of the closure is likewise provided with a body piece or lining 19,

which, with the portion 17 is preferably constructed of suitable heat insulating material.

The outer casing 11 is suitably spaced from the wall 9 of the water heater, thus forming a surrounding air heater chamber 20 for the water vessel, and a burner 21 is projected into the interior of the heater and connects with the source of fuel supply, through the pipe 22. Either liquid or gaseous fuel may be used with the heater, and in either case the necessary type of burner would be employed. A vent opening 23 is formed in'the closure portion 17 and the passage therethrough is regulated by a slide piece or damper 24, which is adjustable in the'pair of guide members 25 secured on the underside of the end closure. A screen 26 overlies the outlet of the vent opening 23 and is adapted for guarding against the entrance of dirt, or the like, into the heating chamber. An outlet flue 27 is located at the top of the heating chamber and is preferably disposed laterally for the purpose of economy in space, after the manner shown in Figs. 1 and 3. Said flue may connect with any other appropriate flue or chimney leading to the outside, or

lead into a stove or hot air heater (not shown), interposed in a suitable location, for utilizing the heat, as may be desired.

The entire exterior surface of the

casing walls

11 and 12, and the rear wall portion 9 of the heater, are covered by a suitable heat insulating material 28, ofasbestos or the like, to the end that the heating contents of the heater may be conserved; and the flue 27 is in like manner covered, as shown.

The water circulating system consists of a water supply pipe 40, which leads to an expansion tank, or any source of supply, and also preferably connects, through a connection not shown, with the heating system at its terminus in an outward direction. It connects with a drainage pipe 50, controlled by a valve 51, by which the system may be 40 is also, connected by drained. Said pipe and 36. Pipe 29 leads a T 4.1 with pipes 29 through the rear wall of the heater and discharges into the water chamber 10 at a point 30 (see Fig. 2.) Pipe 36 leads through the rear wall of the heater and connects with the coil 36% at a point found convenient, such as at 35. The Water circulates through chamber 10 surrounding the heating chamber and passes out from the upper side thereof near its rear end through a pipe 32, which is connected by a T 42 with a pipe 43 which leads to the radiators, to a coil in the kitchen boiler,

or to other heating members (not shown) where it may be desired to utilize the heat. After continuing through the heating system it returns to the supply pipe 40 and is again heated, over and over, mingling with the supply coming from any appropriate source sufiicient to maintain the pipes and heating system full.

The fluid fuel, such as gas or oil, comlng through pipe 22 is ignited at burner 21 and a draft of appropriate force established by the adjustment of damper 24. The fire from the burner heats the chamber surrounded by wall 8 to a very high degree, heating the water within coil 34 and also the coil in the water acket l0 surrounding said chamber, thus providing two sources of utilizing the heat units in the heating chamber, and providing a maximum heater capacity in an apparatus of minimum size and cost. The air for supporting combustion enters through the vent opening 23 at the front end into the heating chamber and from said heating chamber the air and products of combustion pass through vent opening 37 to the hot air chamber, or jacket which surrounds the waterjacket l0, and from the extreme upper side (see especially Figs. 1 and 3) passes out flue 27 to any location where it may be desired either to utilize the heat, or to discharge the commingled air and ases.

g By this construction a heater is provided that is not only cheap to install and to operate, but it W111 b noted that the heating chamber is completely surrounded by water except at the front, and the water chambers completely surrounded by air, except at the front, thus providing an effective protection and a heater capable of withstanding very high heating tests with only one end lined or protected by fire brick or Other protecting material.

It is obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing from the spirit of my invention, and I therefore do not wish to be limited to such details except as may be equired by the claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
