SIMULATED LOG GAS HEATER Filed. Oct. 19, 1962 2| INVENTOR. 22 RAYMOND R. DUPLER 3 4' WM 6/. pm

ATTORNEY United States Patent 3,181,590 SIMULATED LOG GAS HEATER Raymond R. Dupler, 744 Euclid Ave., Toledo, Ohio Filed Oct. 19, 1962, Ser. No. 231,640 2 Claims. (Cl. 158-100) This invention relates to gas heaters but particularly to those referred to as space heaters, which are ordinarily placed in a room or a fireplace for space heating purposes.

An object is to produce a gas-burning heater of this type having provision for augmenting the air supply to the gas burners for aiding combustion.

Another object is to produce a Simple device for passing air in relatively small streams by convection currents to regions juxtaposed to or contiguous to the burner ports so that better combustion is secured.

A further object is to provide a gas-burning space heater of the simulated log-type, for example, with inserts extending from side to side and having relatively small air passage means to enable air to pass by convection to the burner ports or nozzles to aid combustion.

A still further object is to provide a gas-burning space heater with inserts secured thereto and having a plurality of open-ended air passages for supplying air for cornbustion purposes and also having a gas passage for delivering gas to the outside in the region of such air passages so that air and gas are mixed at the point of combustion.

Other objects and advantages of the invention will hereinafter appear and, for purposes of illustration but not of limitation, an embodiment of the invention is shown on the accompanying drawings, in which- FIGURE 1 is a transverse sectional view of a space heater for burning gas and simulating on its front face a log having bark thereon;

FIGURE 2 is an enlarged plan view of one of the insert tubes which are formed with relatively small openended passages for enabling air to pass to the region of the burner ports for augmenting the air supply thereto, and also being formed with a passage of L-shape to communicate with the inside of the gas chamber to enable gas to flow to the outside in a region surrounded by the air passages;

FIGURE 3 is a front end view of the tubular insert shown in FIGURE 2 viewed on the line 33 of FIG- URE 2; and

FIGURE 4 is a rear end view of the insert shown on FIGURE 2 and taken on the line 4-4 of FIGURE 2.

The illustrated embodiment of the invention comprises a space heater having an elongate body which may be formed of gray iron casting. As shown, the body 10 is arcuate in cross section so that when viewed from the front it simulates a Wooden log formed with irregularities in the form of hills and valleys 11 to simulate the bark of a log, the front wall being indicated at 12 and the rear wall, which in this instance is of smooth arcuate form, being indicated at 13. The end walls (not shown) of the body 10 are closed and also an upper wall 14 provides a closure. The bottom wall is closed except for an opening to admit the usual gas-air mixture fitting 17 into which extends the end portion of a gas supply pipe 15 which is equipped with the usual manual valve 16. The interior of the body 10 is open to provide a gas-receiving chamber 18, from which gas escapes through a plurality of relatively small ceramic tubes 19 embedded or cased in the front wall 12, these tubes opening respectively to the gas-receiving chamber 18 and to the outside so that gas passing therethrough is ignited, as will be readily understood.

In order to augment the supply of oxygen-containing air to the burners constituted by the tubes 19, a plurality of ceramic tubes 20 which are also cast in the body 10 and extend transversely of the body with the ends flush or approximately flush with the faces of the front wall 12 and rear wall 13. In this instance each of the tubes 20 is formed with a plurality of parallel passages 21 which open at opposite ends to communicate respectively with the rear of the body 10 and the front thereof. In this instance the passages 21 are arranged in equidistantly spaced relation, such for example as shown on FIGURE 4.

In operation it will be manifest that oxygen-containing air can pass freely through the passages 21 from the rear face of the body 10 to the front face thereof and supply to the gas emitted through the sleeves or ports 19 additional air for aiding combustion, thereby increas ing the efficiency thereof. The number of the sleeves or tubes 20 may be varied as desired, depending upon the volume of air required to secure the optimum combustion.

Certain of the tubes, which are indicated at 20a, are of the same construction as the tubes 20 above described, except for the addition of an L-shaped gas passage 22, the inner end of which opens to the gas-receiving chamber 18 and the outer end of which opens to the front face of the wall 12. It will be observed that the passage 20 is disposed centrally of the air passages 21 so that the gas discharged from the passage 22 is mixed with the air from the several passages 21, thereby improving the combustion.

Under some circumstances, all of the tubes may take the form of the tube 20a, or if desired, they may alternate with the other tubes. It should be understood that no critical arrangement of these tubes is required but they may be arranged in the order to achieve the most eflicient combustion of gas as may be empirically determined.

Numerous changes in details of arrangement, construction and choice of materials may be effected Without departing from the spirit of the invention, especially as defined in the appended claims.

What I claim is:

1. A gas heater comprising a hollow body providing an illuminating gas-receiving chamber and having spaced front and rear walls, means for delivering an air-illuminating gas mixture to said chamber, gas-emitting burner openings arranged at spaced intervals along one wall of said body, and tubes extending transversely through said body, each tube having a row of relatively small open-ended passages extending end to end for enabling air to pass freely by convection in small streams from one side of the body to the other to augment the air supply to the burner openings.

2. A gas heater comprising a hollow body providing 7 an illuminating gas-receiving chamber and having spaced front and read Walls, means for delivering an air-illuminating gas mixture to said chamber, gas-emitting burner openings arranged at spaced intervals along one Wall of 5 References Cited by theExaminer UNITED STATES PATENTS Dudgeon 12692 White 158-110 Kobe.
