GAS BURNER Filed May 13, 1927 Patented Apr. 2,1, 1931 UNITED STATES CHARLES I-I. SLAUTER, 0F COLUMBUS, OHIO GAS BURNER Application filed May 13,

This invention relates to improvements in gas burners and has for its primary object the provision of a gas burner adapted to promote uniform and complete combustion S of the gaseous fuel utilized thereby, to produce a burner characterized by its odorless operation and a burner wherein provision is made for securing an intimate and thorough mixture of the fuel with the oxygen of the air to permit of the production of a highly eliicient flame of green, violet and blue appearance.

Another object of the invention resides in the provision of a burner formed to comprise a V shaped frame which is secured to a gas conduit having an orifice in the upper end thereof, the diverging arms of the frame being shaped to support in a horizontal plane, disposed axially above the orilices in said conduit, a flat delector plate, against the under surface of which the gas stream is directed under pressure, whereby the impingement of the gas stream upon the under surface of' the plate serves to break up the stream and to permit of the intimate com mingling of the air therewith, enabling active combustion to take place contiguous to the peripheral edge of the plate. A further object of the invention resides in forml@ ing the supporting frame for the plate so that said frame will not interfere with the combustion taking place around the peripheral edge of the plate.

For a further understanding of the invention reference is to be had to the following description and the accompanying drawing wherein:

Figure l is a vertical sectional view taken centrally through the improved burner comprising the present invention,

Figure 2 is a perspective view of the deflecting plate and its supporting frame,

Figure 3 is a vertical sectional view of a modified form of the invention,

Figure 4 is a horizontal sectional view taken on the line 4 4 of Figure 3.

Referring more particularly to the drawing the numeral l designates an upstanding pipe or conduit through which is led gas, either natural or artiiicial, under pressure.

1927. Serial No. 191,204.

The upper end of the pipe or conduit is substantially closed and is provided axially with a threaded port for the reception of a removable tip 2 in which is provided a gas orifice 3, which may be of any appropriate diameter dependingl upon the kind of gas employed and also the pressures utilized. One of the features of the invention resides in enabling the burner to operate with tips possessing orifices of varying area, the burner permitting of eiiicient combustion regardless of the artilicial diameter of the gas port which may be selected, although for best economy and eiiciency tips of certain selected area are to be desired.

.In this instance, the outer part of the pipe l, adjacent to its upper end, is threaded for the reception of spaced binding nuts l which are utilized to receive and hold the lower end of a substantially V shaped frame 5 in connection with the pipe. This frame comprises downwardly extending converglng arms which are substantially triangular in cross-section, the lower ends thereof terminating in a circular web 6 which is provided with an opening for the accommodation of the pipe l, and 'through the medium of the nuts 4 the frame can be rigidly held in its operative position. The upper ends of the frame arms terminate in horizontally and inwardly directed portions 7, which, in turn, terminate in downwardly and vertically directed legs S, the lower ends of said legs being in this instance integrally formed with a horizontally arranged, circular detlecting plate 9, which is arranged in a horizontal plane disposed at an appropriate distance above the pipe l and in axial relation with respect thereto.

By this arrangement it will be seen that the gas stream issuing in a thin long attenuated stream under pressure and at reir tively high velocity from the orifice 3 strikes upon the lower axial portion of the plate 9 and is violently agitated and moved in turbulent eddying waves toward the outer peripheral edge of the deflecting plate. While in this relatively violent stage of agit-ation the gas is` actively commingled with oxygen drawn freely from the atmosphere so that a combustible mixture of highly efficient proportions is produced w ich permits combustion to take place around the peripheral edge of the disk or plate. In fact, in the operation of the burner thlre are no visible evidences of combustion in planes below the under sur` face of the disk or plate, combustion apparently not taking place until the gases have passed the peripheral edge of the disk and are in course of ascension. The color of the flames of combustion is indicative of efficient operation in that the flames take on a vari-colored appearance of blue, violet and green, being a pronou ced blue when the operation of the burner is initiated and then producing the light green shades after the burner has been in operation for a short time and the disk or plate heated, however, the heating of the disk is not essential in procuring effective operation. The burner has the advantage of the usual Bunsen type of burner but has no tendency to flash out or to burn back in the mixer if the gas pressures fluctuate, thereby lending itself admirably for use in heating devices wherein thermostatic controls are provided. Again, through the construction of the device it is not necessary to use screens or the like for preventing the gas mixtures from burning at the proper points, inasmuch as fiuctuation of pressures and volumes in the gas stream w1ll not produce uniform combustion.

In the modified form of the invention disclosed in Figures 3 and al., the upper end of the pipe l has connected thereto a disk l0, to which is secured a plurality of upstanding legs 1l which support a circular plate 12 in spaced relation above the upper end of the pipe l. In connecting the legs 11 near the central portion of the plate l?. the intense heat of the flame will not come into direct contact with the 1l and thereby prevent the same from burning ell', sagging or warping.

'hat is claimed is:

1. In a burner of the character described, a circular flat plate, a gaa conduit having a restricted gas flow orifice therein situated in spaced relationship from said plate to direct a gas stream upon the axial portion of said plate, and a support for said plate connected to the upper surface thereof whereby the under surface and edge of said plate are left free and unobstructed to the gas stream flowing in all directions toward said edge.

2. In a burner of the characler set forth, a circular plate, a gas conduit having a restricted gas flow orifice therein situated in spaced relationship from said plate to direct the gas stream upon the axial portion of said plate, said plate being so supported as to leave the under surface and edge thereof free and unobstructed to the gas flowing radially in all directions under said plate.

In testimony whereof I aflix my signature.
