Jan. 23, 1940 J. E. NEALE ET AL GAS BURNER- Filed Jan. 23, 1959 Patented Jan. 23, 1940 GAS BURNER John Ernest Neale and Albert Guest, Coventry, England Application January 23, 1939, Serial No. 252,486 In Great Britain November 24, 1937 2 Claims.

This invention relates to coal-gas or other gas burners, and particularly to such as are for use in geysers, where a plurality of liames can emanate from diierent openings.

Our main object is to provide a simple and inexpensive but eilicient gas burner.

A gas burner, according to the invention, includes a gas-supply pipe with a pin-prick or like small hole therein, and a short tube with diametrically-opposite through 'holes in it to allow of it being slipped along the pipe and positioned thereon with the pin-prick or like small hole lying substantially in the main axis thereof, the tube being of such size as to leave spaces on opposite sides of the pipe along which air can be drawn to mix with the gas issuing from the small hole and to form therewith a combustible mixture in the interior of the tube, and the tube having its end on that side of the pipe adjacent the small hole shaped as an appropriate outlet opening.

The invention further consists in a multi-jet gas burner including a gas-supply pipe with a series of spaced pin-pricks or like small holes in the face which will be uppermost when the pipe is horizontal' and the parts of the burner are properly assembled, the pipe having associated with each small hole a short tube as above specified.

The invention further consists in a multi-jet gas burner including a plurality of spaced gassupply pipes arranged as specified above.

In the accompanying drawing:

Figure 1 is a perspective view of a multi-jet gas burner, for a geyser, according to the invention; and

Figure 2 is a sectional view thereof.

In the construction shown, use is made of a main gas pipe I I of relatively large bore to which are connected a plurality of spaced, parallel, transverse gas-supply pipes I2 of smaller bore. Along the upper faces of these pipes I2 are provided at intervals small holes I3, of the size of pin-pricks, through which the gas can issue.

Associated with each of these small holes is a mixing chamber I4 terminating with an outlet opening I5 through which the combustible mixture can issue to be ignited.

The mixture chambers are formed in short tubes I6 of an internal bore just slightly greater than the external diameter of the pipes I2, so that they can be provided with transverse through holes toy enable them to be threaded thereon and secured in upright position to coact with the small holes I3, as shown. The small holes lie on the respective axes of the tubes I6.

Air for mixing with the gas issuing through the small holes can be brought in through the lower ends of these short tubes and along opposite sides of the spaced parallel pipes I2. Their upper ends may be attened as shown to provide appropriate outlet slits through which the combustible mixture issues.

In this way the gas for the individual flames is split up before air is mixed with it, and the resulting small dimensions of each mixture chamber and the small amount of the mixture being dealt with therein effectively` prevent the possibility of blow-back occurring, Whilst in addition it is possible to ensure that the combustible mixture is a very satisfactory one, whereby the burner has a high eiciency.

What we claim as our invention and desire to secure by Letters Patent of the United States is:

l. In a gas burner, a distributor lpipe in communication with a source of gas supply and having its axis arranged substantially horizontally with a gas escape orice in the upper portion of said pipe, and a mixer tube having its axis arranged substantially vertically and being of short vertical length, said mixer tube being of a horizontal diameter appreciably greater than the vertical diameter of said distributor pipe, said mixer tube being composed of lower and upper sections, said lower section being substantially cylindrical in form and having diametrically opposite openings in its side Wall of a diameter to t snugly over said distributor pipe whereby to leave substantial vertically uninterrupted air passages within said lower section at opposite sides of said distributor pipe, said diametric openings of said lower section being spaced above the bottom edge of said section, said upper section of said mixer tube having ilat mutually sloping side Walls and a burner slit at the upper ends of said flat side Walls, the length of said slit extending at substantially right angles to the axis passing through said diametric openings whereby the end portions of said slit will lie in substantially vertical alinement with the vertical air inlet passages in the lower section.

2. In a gas burnena distributor pipe in communication with a source of gas supply and having its axis arranged substantially horizontally with a gas escape orifice in the upper portion of said pipe, and a mixer tube having its axis arranged substantially vertically and being of short vertical length, said mixer tube being of a horizontal diameter appreciably greater than the vertical diameter of said distributor pipe, said mixer tubebeing composed of lower and upper 10 tion of said mixer tube having flat mutually sloping side walls and a burner slit at the upper en ds of said flat side walls, the length of said slit extending at substantially right angles to the axis passing through said diametric openings whereby the end portions of said slit will lie in substantially vertical alinement with the Vertical air inlet passages in the lower section, said inclined at walls being substantially triangular in form n with their apex portions directed downwardly whereby the at walls extend down very close to the gas oriI-lce and extend gradually out to the end portions of the slit.
