- ork city, in the county and State of New i'ork, temporarily residing in the cityof l ittsburgh, in the county of Allegheny and State of Pennsylvania, ha,e invented certain new and useful Improvements in Combustion Apparatus, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to combustion apparatus for any and all uses, especially as heaters, furnaces, etc. 7

The method herein involved is not herein claimed, as it forms the subject-matter of my application Serial No. 533,775,.fi1ed Sept. 26, 1910. I i

The objects of the invention are to'improve combustion and to produce a convenient and efficient form of apparatus for various heating and industrial purposes.

The invention involves mechanical parts for spraying or jetting into a combustion chamber both a gas or gaseous fuel and combustion-supporting gas,'-such as-air or oxygen.

In the accompanying drawings, illustrating the principle of my invention and the best mode now known to me of applylng that principle, Figure 1 is a vertical, central elevation of a form of apparatus embodylng my invention; and Fig. 2 is another view, mainly in elevation but partly in vertical section, of another form of apparatus embodying my invention.

In the apparatus, any suitable gas or gaseous mixture may be used, but it IS particularly intended for the burning of natural and other gases requiring an especially high percentage of air forperfect combustion.

In the drawings, the bunsen 30, having the usual air-controller 30*, is formed with an enlarged head 31 containing a gas or other fuel chamber. The central portion of the outer wall of this chamber is imperforate at 32 and surrounded by a perforate wall 33, the imperforate and perforate walls 32 and 33- forming what may be considered as the burner-plate or head of a Bunsen burner. The perforations are indicated by 34. Adjacent to the head 31 is a casing 35 containing a combustion chamber, which is separated from the gas'or fuel chamber in Specification of Letters .Patent.

the head 31 by said perforate wall 33. The

- on the imperforate wall 32, which is prefer- I ably opposite. the tubular portion of the bunsen. The wall of this pipe 36 is annularly perforated at 37, and the combustion chamber 35 is provided with out-going suc tion pipes 38 which communicate with a vacuum producing and maintaining device 39, the fan being indicated by L0 and driven by a motor, or in any other suitable manner. In this case, air and gas are mixed in the bunsen and drawn into the fuel chamber 31.

by the suction of the vacuum producing and maintaining device; and the gas or gaseous fuelis jetted into the combustion chamber 35 through the perforations 3% during the suction operation of the vacuum producing and maintaining device; and simultane fuel, air is drawn through the pipe 36 and drawn jet-wise through the holes 37 into union with the fuel jets by the suction. By lifting the lid 41 of casing 35,the combustible mixture in the combustion chamber is readily ignited.

Of course the arrangement'of the described parts may be varied without departure from my invention, depending on the particular uses for which apparatus embodying this invention is intended. The fan is the preferred form of vacuum producing and maintaining apparatus, though any means of artificial suction may he used, and serves to draw air or other combustion-supporting gas to the various points of ignition, when the apparatus is in use, to im prove the combustion and to remove products of combustion outwardly from the amp paratus.

' The imperforate portion 32 being placed, in that form of. the invention now shown, opposite the delivery end of the bunsen, serves to spread out the inflowing gas into the chamber of the enlarged head 31, so that the perforated wall may be of considerable area, depending on the cross-sectional 'ously with this jetting of the combustible nous fuel. shouldenter jet-wise-into the combustion I area er the tube of the biuisen. While the imperforate portion 32 may be perforated in some sizes of the apparatus and for some uses, yet when the wall in portion 32 is imperforate, as shown, it functions as a lateral deflector of. the incoming. gas, and this is useful in some installations.

" The'adv'antage of this type of" structure is the intimate mixing and commingling of the gaseous fuel and air or combustion-supporting gas by the jet-like form in which the air is brought in contact with the gase- To obtain the best results, both chamber. Thus two continuous sprays of gaseous fuel and combustionsup'porting gas meet and -mix in the combustion, chamber.

As the strong suction makes it possible to direct the combustion-supporting gas in any direction, by an appropriate arrangement of parts, it has an especial value in industrial uses, breaking up the molecules of gas and the end of the bunsen and perforated at 134 around the imperforate portion.--A

cover or'heater-p1ate135 is provided for casing 131, and is shown provided with a central tubular portion 136 provided around its circumference with a plurality of holes 137 whereby air or other combustion-supporting gas is jetted or sprayed into the combustion. chamber 135,.the gaseous fuel admitted thereto through the perforations 134 being crosscommingledjet-wise with the air jets. Gonduits'138 lead from the combustion chamber to suction fancasing 139 provided with a'suction fan 140. Gasing 139 has an exhaust port 144:. Under the influence of the suction the content of the combustionchamber is partially vacuumized during combustion, allowing the mixture to be burned to take a continuously attenuated molecular condition, whereby combustion is greatly intensified; I Thesuction apparatus is operable to cure continuous, uniform suction.
