GAS-BURNER.

Specification of Letters Patent.

Patented. Dec. 3, 1 9%? Application filed February 8. 1907- Serial No. 356.392.-

To all whom it may concern:

Be it known that I, GILBERT A. Cnor'ro, a citizen of the United States, residing at Reading, county of Berks, State of Pennsylvania, have invented a new and useful Gas- Burner, of which the following is a specifica- My present invention consists of a novel and useful construction of a gas burner by the employment of which the amount of gas which it is necessary to use is reduced to a minimum and not only a more economical but a better light is produced;

It further consists of a novel COIlStI'llGtlOD of a container which is adapted to be readily inserted in burners now in use and comprises in its broad scope'a casingor sleeve, the upper and lower ends of which are apertured, said apertures being closed by means of ca s of gauze or other suitable material and t e space within the sleeve or container between said caps is filled with mineral-wool, cotton,

asbestos, animal wool or any equivalent material, although I have found in pra'ctice that a combination of mineral wool and animal wool gives reliable and satisfactory results.

It further consists of other novel features of construction, all as will be hereinafter iully set forth.

For the purpose of illustrating my-inv'en tion, I have shown in the accompanying drawings embodiments thereof which have been found in practice to give'satisfactory andreliable results, although it is to be understood that the various mstrunientalities of which my invention consists may be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities, as in the embodiments herein shown.

Figure 1 represents a side elevation of a gas bracket showing in sectional elevation a gas burner embodying my invention attached thereto. Fig. 2 represents a erspec tive view of the contaiueremploye in detached position. Fig. 3 represents a side elevation of a portion of a bracket showing in sectional elevation another embodiment of my invention. Fig. 4 represents a rspective view, showing a container for t e min- Similar numerals'ei reference indicate cor. responding parts in 'the figures.

eferring to the drawings, 1 designates the rod of a gas burner having secured thereto an elbow or extension 2, the upper end oi which is threaded in the usual manner,

adapting the same to coact with the internal thread 3 of the burner casing 4:. T he casing 4 at its lower end is provided with an enlarged diameter 5' from which extends upwardly a smaller diameter 6, and the casing 4 is still further reduced to form a shoulder 7 and a reduced diameter 8.

9 designates a burner of the usual construction which is adapted to be retained in the reduced end 8 of the gas burner casing 425 10 designates a sleeve, tube or container, preferably of brass or aluminium which is adaptedto closely engage the reduced diameter 0r bore 6 of the casing 4, said sleeve or tube having inserted in its upper end a strainer or gauze 11, it being noted, as seen in Fig. 1, that a similar strainer or gauze 12 is employed to clos'e the lower end of said container, the ends of said strainers or caps Hand 12 being deflected inwardly so as to engage the internal walls of the sleeve 10.

-The s ace between the caps 11 and 12 within the seeve I0 is filled with mineral wool, natural wool, cotton or equivalent material or a combination of such materials, it being apparent that any improper movement of. said material after it is placed within the tube or sleeve 10 is positively prevented owing to the manner in which the caps 11 and -12 are carriedwithin the tube or sleeve 10,

said caps being preferably flush with, or terminating slightly within the ends of the tube or sleeve 10. The end of the casin 10 is adapted to abut against the shou der 7 formed by the reduced diameter of the gas burner casing 4, as will be readily apparent from Fig. 1.. r

In the embodiment shown inFigs. 3 and 4,

I have shown a slightly modified construc.-

tion, although it Wlll be apparent that the same principle is employed and the same result attained by the employment of such a construction. In this embodiment, 13 designates a bracket having a threaded extension 14 on which the lower portion or sleeve 15 of eral wool or equivalent material, in detached the casing 16 is ada ted to be screwed or position.

otherwise secured.

he lower casing 15 is deflected outwardly at its upper end, as seen at 17, and 1s Internally threa ed so as to form a shoulder 18.

19 designates the upper casing member, the lower end of which is threaded and adapted to engage with the internal thread of the deflected portion 17 of the lower casing and thus secure the two casing members 19 and 16 in fixed relation with each other. The casing 19 converges or is deflected inwardly,

as seen at 20,'and from this converging portion 20 extends a reduced diameter 21 within the end of which the tip 22 of the usual construction is adapted to be seated.

23 designates a sleeve, tube, or container, the outer contour of which is such that it is of t e portions 16 and 19 of the two casing members and this sleeve or container is adapted to be filled with mineral wool 24 in a similar manner to that already indicated with respect to Figs. 1 and 2, it being noted that the upper end of this container 23 is.

closed by means of a screen or gauze cap 25 and that the lower end 1s closed by means of ascreen or gauzecap 26. In the present instance, however, instead of employing a I The manner in which my novel gas burner is assembled will be readily a parent to those skilled in the art, and in the embodiment seen in Figs. 1 and 2, it is simply essential to fill the sleeve 10 with mineral or'animal wool or other suitable material and then insert the gauze caps 11 and 12 in osition after which the sleeve 10 is inserte in the casing 4 so that it will closely engage the internal diameter 6 and abut against the shoulder 7 of said casing 4.

In the embodiment seen in Figs. 3 and 4, the container 23 is filled with mineral wool, animal wool or equivalent material after which the gauze caps 25 and 26 are inserted in each end. Theends of the container 23 are then swaged in any suitable manner so that the container 23 will conform to the internal diameter of the portions 16 and 19 of the two casing members when the parts are in assembled position. The sleeve 15 of the lower casing is secured in place on the extension 14 of the bracket 13. The container '23 is then placed within said lower casing so that the lower converged end thereof rests upon the upper end of the threaded sleeve or tube 14. 1 1e upper casing is then placed over the upper end of the container 225 and adapted to closely engage the inner diameter more perfect combustlon will be obtained.

owing to the employment of the threads at the end thereof and the internal thread on the deflected. portion 17 of the lower casing, the two parts may be readily united so that there is .no possibility of any improper movementof the container 23 relative to the upper and lower casing members of the burnpr, and the upper aperture 27 of the container 23 will register with-the reduced diameter 21 of the upper casing member.

The gas passing through the gas burner will be obliged to pass through the up er and lower screens or ape'rtured caps and t ough the mineral wool, animal wool, cotton or' equivalent material or a combination of such material so that any foreign material will be removed therefrom.

There is often difficulty in gas burners of this type owing to the gas having too large a proport on of air, so that a proper mixture of air and gas is not supplied to the burner tip. When a construction embodying my invention is employed the passage of the gas to the tip will be obstructed in such a manner that the air and gas will be brought into intimate contact with each other so that as the mixture passes from the chamber 8 or 21 to the burner tip 9 or 22 respectively, the gas and air will form. a homogeneous product and a It is a well known fact that the pressure of the gas passing through the conduits in cities and towns varies a great dealat difi'erent hours of the day, the ressure being greater during the day and v decreasing proportionally at night when more lights are employed. When a construction embodying my invention is employed the variation in the pressure of the gas at the burner tip is reduced to a minimum, since the same must pass through the comminuted material within the container before it "reaches said burner tip. A construction embodying my invention can be readily employed in burners now in use and can be readily and quickly assembled or disassembled when desired.

It has been found in practice that by the employment of a construction such as herein illustrated and described, the-amount of gas used is largely decreased andthereby the cost of operating said lights and furthermore a better and more efficient light is produced.

It will now be apparent that I have devised a novel and useful construction of a gas, burner which embodies the features of advantage enumerated as desirable in the statement of invention and the above description and while I have in the present instanceshown and described embodiments thereof which have beenfound in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit and sco e of the invention or sacrificing any of its a vantages. l30
