GEORGE P. SCHMITT, OF OAKLAND, CALIFORNIA. I

I GAS-HEATED RADIATOR.

Application filed March 12, 1923. serial no. ceases.

To [1. whom it may concern:

Be it known that I, GEORGE P. SCHMITT, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Gas- Heated Radiators, of which the following is a specification.

This invention relates in general to heating stoves, and in particular to stoves of the gas-radiator type in which the source of heat is gaseous fuel, the hot gases circulating through the radiator for warming the surrounding air by direct radiation.

An object of the invention is to 'produce a radiator of the above type, in which the combustion is effected within the radiator and near the top thereof, and the resulting hot air and gases caused to pass downward through one side of the radiating unit and up through the other side.

A further object is to provide such a radiator with a preheating chamber for warming the incoming air to the same.

Another object is to produce such a radiator in which the hot air and gases are superheated just before being discharged from the radiator.

And still another object is to provide such a radiator with a damper to shunt hot gases immediately to the discharge fine, to dry out and heat the latter for the promotion of an immediate and effective induced draft. This latter object is of great importance in cli-' mates where there is considerable moisture in the air, as the vent pipe to'the atmosphere will not draw effectively unless it is thoroughly dry and free from moisture.

With the above and other objects in view, the means by which I secure the efiiciency of my invention will be fully set forth in the description and drawings of that embodi ment of my invention which I have selected for illustration, and which is the best as yet devised by me.

In the accompanying two sheets of'drawin s:

igure 1 is a side elevation of a five-loop radiator constructed according to my in vention.

Figure 2 is an end elevation of the same.

Figure 3 is a vertical longitudinal section taken on the line A-A of Fig. 2.

Figure 4 is an enlarged fragmentary section of one of the filler loops.

1' Figure 5 is a similar section of the middle Referrinlg to the drawings and the figures thereof:- have illustrated a five-loop radiator, though a greater or lesser number of loops may be used according to the space to be warmed. Each loop of the series is atelv below the superheater which constitutes the combustion chamber. Otherwise the individual loop units are separate or insulated from each other and fitted together in cement in any suitable way, such as by common male and female joints as shown.

Near the top of each loop is its fire box 3. The fire boxes are open toward each other so as to make a. continuous fire box from end to end of the radiator, closed at the ends by the walls 4 and 5, in one of which ast, is a mica covered peep hole 6, and in the other of which is a door and hole 7 throughjwhich the gas may be lighted. In the lower part of the fire box, innnediatel below the peephole 6 and the lighting ho e 7 is the burner 8, which may be in the usual form of a perforated pipe as shown.

The lower half of the fire box is the preheating chamber and is open to the circumambient air, which air, when the burner is lighted, rises and mixes with the gases of combustion. The mixed hot air and gases, rising against the top 9 of the fire box are reflected and pass over the baffle-Wall 10, and down to the bottom of the loop in the le 11 thereof, and thence up in the other leg 1% and into the superheating chamber 1 2.

In the superheater the gases are further heated by the top 9 of the fire chamber and take a lateral and spiral courseto the mlddle loop 18 and pass out at the flue 13. The effect of superheating is to vaporize entrained moisture, reheat the spent gases and increase the draft.

In the middle loop 18 of the series, l preferably make an opening from the fire box till tlti

that in starting the operation of the radiilw ator the hot air and products of combustion,

may pass directly to the flue 13, thus startmade somewhat higher opposite the opening 14, as seen inv Fig. 5 to cause an increased draft effect when the damper is. opened. i In operation, the issuing gas is lighted and damper opened as shown by'the dot and dash lines in Fig. v5, to create an immediate draft as previously explained. In the interim, the flame of the burner impinging upon the sidewalls of the continuous fire box, has caused the said walls'to become hot, thus starting the preheater to function efficiently. A

The damper is then closed and complete circulation effected. The cold air is drawn into the preheater and heated by the walls thereof before the said air passes through the flame. The hot air and gases in the separate loops complete little more than a fullcircuit, as shown by the dot and dash arrows, and collect in the superheater and are again heated by the flame impinging on i the division wall 9, thence the horizontal column of moving products of combustion pass to and through the vent/13 to the at mosphere.

It will be observed that the' radiator when in use, not only heats the room but'causes Y a constant ventilation of the same aswell.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, .together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired, as fall within the scope of the appended claims.

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

1. In a stove of the gas-radiator type, a

radiating unit having a fire box near the top thereof and a superheating chamber above said fire box, the. chamber being open for circulation.

2. In a stove of the gas-radiator type, a radiating unit having a .burner, fire box and discharge flue near the top thereofand having an openin from said fire box direct to the discharge ue, and a damper adapted to close the said opening.

3. A stove of the gas-radiator type composed of separate radiating units connected .together, and each unit having a fire box near the top thereof, with an open bottom, the said bottoms forming one continuous opening to the atmosphere.

i 4. A stove of the gas-radiator type composed 'of separate radiating units connected together, and each "unit having a tire box near the top thereof, and a superheating chamber immediately above said fire box, the said fire boxes opening into each other to form a continuous fire box and the said superheating chambers opening into each other to form a continuous superheating chamber. 4 e

7 A stove of the gas-radiator type, comprising a burner, a combustion chamber, a

superheating chamber, apreheating chamber and circulating tubes leading from the combustion chamber to the superheating chamber, the latter provided with an outlet for the products of combustion, the burner being positioned in the preheating chamber and whichlatter also'forms the air inlet, the combustion chamber being positioned between the preheating and superheating chambers, and the latterchamber being the uppermost part of the stove.

Intestimony whereof I 'afiix my signature.

GEORGE P. SCHMITT.
