mmmll E i I JAMES P. MORLEY AND GEORGE'W. KITE, JR, OF CHICAGO, ILLINOIS, ASSIGNORS TO BASTIAN-MORLE'Y 00., OF CHICAGO, ILLINOIS, A CORPORATION.

GAS-BURNER.

To all whom it may concern:

Be it known that we, JAMES P. MORLEY and GEORGE W. KITE, Jr., both citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gas-Burners for lVater- Heaters and the like, of which the following is a specification.

The present invention relates to gas burners of the type shown in U. S. Letters Patent No. 1,072,072, which were granted September 2, 1913 to Bastian-Morley Co., as the assignee of William B. Bastian.

Generally stated the object of the invention is to provide a burner of thetypteiereferred to of improved construction-+i'mproved particularly with regard to. its efiis ciency; the means for holding it in proper position with relation to the pipe' or other device by which it is supported and which passes through it centrally; and its simplicity and consequent cheapness of construction.

To these ends the invention consists in the features of novelty that are hereinafter described with reference to the accompanying drawings which are hereby made a part of this specification and in which:

Figure I is a sectional elevation on a small scale of the lower portion of a water heater such as is shown in the patent aforesaid, with the improved burner applied thereto, the burner being viewed from the rear side.

Fig. II is a plan view of the improved burlner of the preferred form and on a larger sca e.

Fig. III is a vertical section thereof on the line IIIIII, Fig. II-looking in the direction of the arrows.

Fig. IV is a plan view of the lower member of the burner shell.

Fig. V is a plan view of a burner involving the invention under a slight modification.

Fig. VI is a section thereof on the line VIVI, Fig. V looking in the direction of the arrows.

Referring first to Fig. I, 10 represents a tank such as is customarily used for kitchen boilers, or water heaters. Its-bottom, 11, is setup a considerable distance below its lower margin leaving a depending apron, 10 providing a chamber 12, in which is located a so-called spreader, 14, the burner,

15, and a bent pipe the upper end of the longer vertical branch, 16, of which communicates with the bottom of the tank, the horizontal branch, 17, of which extends beneath the bottom of the burner, and the shorter vertical branch, 18, of which extends upward through the burner and communicates with the bottom of the spreader, 14. The shell of the burner comprises a saucershaped bottom member, 19, and a top member or plate, 20, through which the jet 01'1- fices, 21, are formed. The bottom member of the shell has a radially disposed notch, 22, and a centrally disposed opening, 23, through which the supporting pipe, 18, passes centrally. The opening, 23, is of larger diameter than the pipe, 18, so as to leave around the pipe an opening for the passage of air for supporting combustion and this adds materially to the efliciency of the burner.

The opening, 23, is bounded by the inner wall, 24, of the bottom member, 19, of the burner shell. This inner wall, 24, is of C- shape and its ends join the inner ends of the side walls,-25, of the notch, 22, and the outer-1' ends of these walls, 25, in turn, join the ends of the C-shaped outer wall, 26, of the bottom member of the shell. These Walls, 24, 25 and 26 join the bottom, 27, and result in a hollow shell having in its top a C-shaped depression, 28. The walls, 25, of the notch, 22, are continued inward in the form of a U-shaped yoke, 29, the bend of which embraces the front side of the supporting pipe, 18, and prevents the burner from moving rearward relatively thereto beyond a position concentric therewith. The forward movement of the burner relatively to the pipe beyond this concentricity is prevented by a bar, 30, which lies against the rear side of the pipe, 18, and has means for engaging the burner shell. Any suitable means may be used for this purpose. Preferably the bar has at its ends down-turned legs, 31, which occupy sockets in the burner shell. Preferably these sockets consist of perforations, 32, formed through the jet plate, 20, and these perforations may be formed through the plate opposite the depression, 28, of the shell, so that the legs, 31, project downward into the interior gas chamber, 28, of the burner, as shown in Figs. V and VI, or they may be formed through portions, 20, in the form of lugs or projections which extend from the inner margin of the plate and project over the central 0 ening, 23, of the shell, as shown in Fi s. I and III. This latter arrange- .ment that the bar is not subjected to such an in tense destructive heat and the lower ends of its legs are 'not subjected to an upward pressure of the gas that would tend to lift them free of their sockets and permit the bar to become dislodged. With the arrangement shown in Figs. V and VI, the bar will fit between the nipples of the burner and the nipples that engage the rear side of the bar will assist in preventin the burner from moving forward relative ly to the pipe, 18.

The jet plate may be conterminous with the outer surfaces of the walls, 24, 25 and 26 of the bottom member, .19, of the shell and rest flat upon top of them as shown in Figs. V and VI or the said walls may be rabbeted at top as shown at 33, and the margins of'the p ate, 20, fitted in said rabbets as shown in-Figs. II, III and IV.- In any event the top and bottom members of. the shell are firmly secured together by bolts, 34.

Gas is admitted to the interior of the burner through openin 35, formed through the bottom, 27, at points that are diametrically opposite each other and equidistant from the notch, 22. These openings communicate with the rear ends ofpass'ages 36, which are formed in ribs that are forme on the under side of thebottom, 27, during the process of casting the bottom member, 19. The forward ends of these passa s, 36, communicate with the interior of av 01- low spud, 37, which is formedvon the front of the bottom member, 19, of the shell at a point diametrically opposite the notch, 22,

and equidistant from the openings, 35. The

discharge branch of the mixer, 38, communicates with this spud,'whence the gas passes in equal volumes through thepassages, 3i},-

and is discharged through the openings, 35, into the burner, where it is equally distributed. This effectually prevents back firing, this prevention being due partly to the even distribution of the gas within the burner,

partly to the tortuous course ofthe gas passage-first upward through the spud, 37, thence horizontally through the 36, and thence. upward through t e openlugs, 35, and partly to the comparatively great length of the passages, 36. It is ound in practice that even if the flame should succeed in passing back through the openings, 35, it is smothered in the passages,

36, before reaching the mixer, or even the spud,37.

What we claim as new is:

' 1. A burner'having a hollow shell, said,
