Specification o! Letters Patent.

Patented Nov. 3, 190B.

To all whom 'it mafy concern:

Be it lcnovv'nv that I, AARON L. Veo a. citizen of the' United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Inverted Gas-Burners, of which the following, when taken in connection with the drawing accompanymg and formi u part hereof, is u full and complete descrlption, sulicient to enable those skilled iu the ort to understand, make, and use the same.

This invention relates to inverted gas burners provided with u Bunsen burner und a mantle; and the object ofthe invention is to obtain a burner by means of which, when the same has burned until the supply pipe, adjacent to the mantle, is heated, suiiicient gas will be supplied and with suicient force to induce c suicient supply of nir so that no smoke will be produced or emitted by the burner and a blue llame, as it is called, will continuously be produced.

A further object of the invention is to obtain u burner of the kind named which may be easily attached to an ordinary gas pipe, in lace of the ordinary tip or in place of an ordinary W'ellsbach burner, by one not particularly skilled in the art, and properly ad- 'nsted to burn as desired and to produce a lue flame.

In the drawing referred to as forming a part of this specification Figure 1 is a side elevation of un inverted burner embodying this invention, showing a mantle thereon in suitable position for use. Fi 2 is a side elevation, on an enlarged sca e. of the end of the pipe to which an inverted burner embody' this invention may be attached. Fig. 3 1s a vertical sectional view of the Bunsen burner formi a part of this invention. Fig. 4 is o verticsectional view, on an enlarged-sle, of the upper end of the Bunsen burner fornuis-:g a part of this invention, and of the parts a )scent thereto, with the lower end of the onse neck of the burner. Fig. 5 is a vertica sectional view of a diminishing thimble fox-min an element in the device embodying this invention. F' 6 is a vertical sectional view of a modi cation of the diminishing or thimble of the device. F' 7 is an elevation of the base of the needle va ne forming an element in the gas burner embed this invention, and F' 8 is a top plan view of the base of the nee le valve'.

.A reference letter applied to des ate a glven art is used to indicate suc part thro out the several figures of the drawing, w crever the same appears.

A is an ordinaryl ell.

AB is a Bunsen tube. Tube B is provided with the base C' and with air regulating sleeve E.

F is a. perforated tube.

G is an adjustable diminishing tube (see Figs. 2 and 3).

The air apertures in tube F are lettered j, f. Base C consists of the knurled part C provided with screw threads therein [itt-i fr over the ordinary screw threads of gas e l A, the screw threaded parts C and Ca and the needie C. there are provided the holes Cs thro h which gas may flow to around the needle and underneath the cap D. Cap D is provided with internal screw threads fitti over the screw threads C of base C, a with an aperture fitting over C of base C so that by turning such ca the aperture is more or less closed vb n le C. The foregoing described n e valve and base obtained by base C and cap D is the ordinary construction.

K is the goose neck of the inverted burner and L is the mantle thereof. In the device embodying this invention the goose neck K is attached to the Bunsen burner B by means of the interposed support M.

Su port M pre erably com rises the enlarg part m of the end of t e neck K, and the tube m' provided with the enlarged part m2 enga with enlarged part m of goose neck K, an provided with the enlarged part m formina wind guard to air apertures f, f, in tube m* 1s a. groove m the upper end of tube m' to prevent such tube from falling down on tube E.

It will be observed that diminish G is of less area at the up er and d' end thereof (lettered g) an is the area of the passage through the goose neck K (shown in the l:part of such goose neck adjacent to the e urged part m, in Fig. 4

tube arge g is u ring or ferrule on the upper endof 105 diminishing tube G preferably used when At the base of needle C*I i lower end of neck Kisaj'. m,l nix1ng chamber n 4) is obtained in whlh .the ga's and air d from dmumslnng mixed before the y 'same are delivered therefrom in the goose neck The-diminishing tube G may be raised or loweredin tube F to more or les cove;` apertures. Lt, for the adjustment of the au' sup- Pli gld 'e geen; M' d fr 1n mg e gas an air m theBunsenbumertothegooseneckK through im aperture of less area. than the area of the goose neck that when the end of 2s the goose neck adjacent to the mantle L becomes heated the discharge of such combined air and gos into such goose neck is substantially the same as before the heating.

Having thus described my invention what I claim as new and desire. to secure by Letters Patient is;-

In u gas burner, the combination of a ges nozzle, a. tube secured bo seid nozzle and having air admission openings ndjiwent;

thereto, n. longitudinali movable mixing cup frictionally held wit 1in the tube and arranged to vary the size of the air admission opening, said cup having an exit of less aree than its entrance.
