'WILLIAM S. DAVIS, OF SACRAMENTO, CALIFORNIA, ASSIGNOR OF ONE-HALF TO CHARLES E. EMERSON, 0F SUSANVILLE, CALIFORNIA.

BURNER.

Specication of Letters Patent.

Application led June 11, 1917. Serial No. 174,158.

To all whom it may concern.'

Be it known that I, WILLIAM S. Davis, a citizen of the United States, residing at Sacramento, in the county4 of Sacramento and State of California, have invented certain new and useful Imprpvements in Burners, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in liquid fuel burners and it' is an object of the invention to provide a device of this general character having novel and improved means whereby an intense heat may e generated and wherein the creation of odor is substantiallyentirel eliminated It is also an objectof the invention tofprovide a burner of this general character having novel and improved-means whereby the requisite mixture of air is assured for supporting combustion and creating suiiicient draft to form a flame of material length.

The invention consists in the details -of construction and in the combination and arrangement of the several parts ofmy vimproved burner whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more vconvenient and advantageous for lflsall as will be hereinafter more fully set The novel features of the invention will hereinafter be deinitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wlherein-Y l l Figure 1 is a diagrammatic view partly in elevation and partly in section illustrating a burner constructed ini accordance with an embodiment of my' invention; l

Fig. 2 is a sectional Flg. Sis a fragmentary elevational view with parts omitted illustrating a slightly modified form of my improved burner.

As disclosed in the accompanying drawings, 1 denotes a supporting basket having its upper end opened and provided adjacent its upper end with an annular series of materially large openin 2. As disclosed in Fig. l, the basket 1 1s tapered toward the bottom and isseated within a suitable opening in a support S, said support being preferably the lower end of a heating device as v1ew taken substan- "tially on the line 2-2 of Fig. 1; and

M which comprises a hollow body providedat its margin with an annular series of restricted openings 4. The center of the burner M is provided therethrough with a threaded opening 5 and in which is engaged the depending boss 6 arranged' at the axial center of the supplemental burner B lpositioned above the main burner M and in predetermined spaced relation thereto. The supplemental urner B is-falso of a predetermined diameter less than the diameter of the main burner M. The supplemental burner' B is also hollow and provided at its marginal portion with an annular series -of restricted'- openings 7. A In communication with the chamber of each of the burners M and B is a supply-pipe 8 and 8', respectively, leading from a common source of fuel supply as indicated by the pipe 9.'- Interposed in the pipe 8 coacting with the supplemental `burner S is a needle valve 10 adapted to be automatically operated through the medium of a thermostat T whereby the operation of the burner B may be regulated in accordance with the requirements of practice. The second pipe 8 has interposed therein the manually operated needle valve 11 for controlling the flow of fuel through said second pipe 8. Each of the pipes 8 has also interposed therein the access within the plpe 8 in order to observe the llow of the fuel therethrough.

Surrounding the burner M is a sleeve 14 of a lenv h to terminate above the openings 2 herein efore referred to but below the top or o en end of the basket 1. Positioned within the sleeve 14 and concentric thereto is a second sleeve 15 which surrounds the glass l2 to afford visual to permit the air entering through the openings 2 in the basket 1 to lproperly support combustion while the sleeves 14, 15 and 16 coact to afford flues to result in sufli'cient draft being created as to cause the flames of the burners M and B to be of material length. It has been fully demonstrated in practice that the openings 2, which are materially in excess of the areas of the restricted openings 17 coact with the restricted openings 17 in creating a flame free from smoke and which can be maintained'at a comparatively small cost. In practice it has been fou'nd that theltlames of the burners M and B can be maintained on a pint of fuel per hour. v

The upper face of the burner B at its axial center is provided with the upstanding lug 1.8 to afford means whereby a wrench or other implement may be engaged with said burner B when it is desired to apply or remove the same.

The form of my invention as illustrated in Figs. 1 and 2 is particularly adapted for use in connection with a water heater as embodied in my copendin application executed on even date herewit I have found, however, in practice that my improved burner may be employed with convenience and facility in connection with the creation of dry heat. In this latter luse the burner is adapted to be connected directly with the lower end portion of a flue F as particularly illustrated in Fig. 3. In so using the upper portion of the basket la at each side thereof 1s provided with an outstanding pin 19 with which is adapted to coact a substantially L shaped lug 20 depending from the flue F.

From the foregoing description, it is thought to be obvious that a burner constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly Well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I donot wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

I claim:

1. A device of the character described comprising a basket having its upper end portion provided with openings adJacent its open end, a cup like member resting upon the closed end of the basket, a-hollow burner positioned within the cup like member and resting upon the bottom thereof, a second hollow burner arranged within the cup like member and operatively engaged with the `first named burner, each of said burners bemember and operatively engaged with the first named burner, each of said burners being provided with restricted o enings in their marginal portions, .means or delivering fuel in each of said burners, and means for controlling the delivery of fuel to. each of the burners independently of the other.

3. A device of the character described comprising a basket havin its upper end i portion provided with openlngs adjacent its open end, a cup likemember restin upon the closed end of the basket, a hollow urner positioned within the cuplike member and resting upon the bottom thereof, a second hollow burner arranged within the cu `v,like member and operatively engaged wit the first named burner, each of said burners being provided with restricted openings in their marginal portions, means for delivering fuel in each of said burners, a sleeve surrounding the lower burner and extending above the openings in the basket, a second sleeve surrounding the upper burner and extending above 'the openings in the basket, said second sleeve being positioned inwardly of the restricted openings in the i lower burner, and a third sleeve supported by the upper burner inwardly of the restricted openings therein, the third sleeve also extending above the o enings in the basket, each of said sleeves lbeing provided with restricted openings.
