To. (ZZZ w ham it may concern.

Be it known that I, HERBERT C. MIEVILLE, a subject of the King of England, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Heating Systems, of which the following is a specification.

My invention pertains to heating appliances, and has reference to that class of such devices which are provided with a multiple burner system, such as are employed in large baking ovens, furnaces, heating plants, and other places wherein vapor produced from oil is used as a fuel.

One of the purposes of the present invention is to improve upon the construction of the burner system itself, so as to increase the simplicity and efiiciency thereof.

Another feature of the device consists in the provision of an auxiliary burner which can be used for priming purposes, or for maintaining the generating process after the same has been fully developed.

It is sometimes desired to operate the system at a low point of flame, so as to reduce the degree of heat which is being furnished thereby, but this is difiicult to accomplish on account of the danger of the blaze being entirely extinguished. This danger is largely or completely eliminated in my device through novel features thereof.

The particular construction, arrangement, and operation of the various parts of my invention will be more fully comprehended from the following specification, reference being had to the drawings accompanying the same, in which:

Fig. 1 is a plan view of a heating device embodying my invention, broken away at one end.

Fig. 2 is a cross-section on the broken line 22 of Fig. 1.

Fig. 3 is a plan view of the auxiliary heater, detached, with the hood removed.

4 represents aconduit, of U-shaped form, in which is supported a plurality of burners 5, formed of lava or other non-combustible material, in which are parallel rows of perforations 6, and end perforations 7 At thejoints of the burners 5 are bolts 8, by means of which the sides of the conduit are clamped tightly against the burner blocks, holding them rigidly in place. At one end there isconnected with the conduit 4 anintake pipe 9. I A

Supportedin proximity to the conduit 4 is an auxil ary burner, comprising a casing 10, communicating with the conduit 4 by means of a plpe 11, provided with a shut-off valve 12. Supported in the upper part ofthe casmg 10 1s a burner 13, having rows of perforations 1'4. Centrally of the burner 13 is a wicking 15, and surrounding the same is a small trough containing a wicking 16. Above the burner 13 is a coil 17 connected by a pipe 18 with a feed-chamber 19, the upper part of which has a discharge pipe 20 opening into the intake 9. Supported on the burner 13 is a hood 21, provided with perforations 22 in its sides and an opening 23 longitudinally of the top thereof.

In operation, the upper part ofthe auxillary burner 13 is provided with a small quantity of inflammable liquid, and the same ignited. A supply of oil is then introduced to the coil 17' from any suitable source, which oil becomes vaporized, the gas therefrom being conducted through the pipe 18, chamber 19, and pipe 20 to the intake 9,

from whence it passes into the pipe 4, and

through the openings in the burners, above 7 which it is ignited and consumed. After the flow of the vapor has been fully established the valve 12 is opened, permitting a portion of the gas to pass into the auxiliary burner, and through the openings therein, such gas then supplying the flame by means the generating process is continued.

The hood 21 tends to concentrate the heat about the coil 17 intensifying the same, and producing better results. It also limits the amount of air which mixes with the gas above the burner, which is of. special advantage when the supply of such gas is reduced to a minimum, when it is desired to operate the system at a low point of heat.

.It also acts as a shield to prevent the flame from belng extinguished by air currents when turned to a low point.

.The arrangement of the perforationsfi in parallel spaced apartrows adds to the efficiency of the blaze." Air passes inwardly be-. tween the jets of gascoming through the perforations, mixing with such gas and forming a product for a central flame of great intensity. The" tendency of the v exhausted gases is'to move upwardly, and free};

of which currents of air are brought in from the side. A constant circulation of air is thus assured, producing the best results for combustion and heat efliciency. v

It is usual to ignite the gas for a series of burners at one end of the conduit, the flame spreading from one to another of such burners. This process is aided in my invention by the end perforations 7 which cause the flame to pass quickly from one of the burners 4 to the next one.

By constructing the conduit 4 of U shaped form, it can be cheaply and easily produced, by bending a piece of sheet metal into a desired shape. I

If desired, the a vapor can be primarily generated by other means than the burner 13, such, for instance, as an electrical gen- A hood for said auxiliary heating device, having openings at the sides and top thereof; and a coil Within said hood, adapted to re ceive a quantity of liquid fuel and convey it in vapor form to said first-named heating device.

In testimony whereof I afllx m HERBERT C. Mll
