BENJAMIN EDWARD MEACHAM, OF LORAIN, OHIO, ASSIGNOR TO AMERICAN STOVE COMPANY, OF ST; LOUIS, MISSOURI, A CORPORATION OF NEW JERSEY.

BURNER FOR WATER-HEATERS.

To all whom it may concern:

Be 't known that I, BENJAMIN E. MEACHAM, a citizen of the United States, residing at Lorain, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Burners for Water-Heaters, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in burners for water heaters.

The object of my invention is to provide an improved burner in which the mixing cone is well protected from condensation and overheating, and at the same time pro vide a burner in which there will be no back fire. I

Another object of my invention is to provide a burner of this. character which is easy to assemble and repair and which has no packed or cemented joints, and at the same time produce a cheap and efiective burner which will properly distribute the heat and cause perfect combustion.

A still further object of my invention is to provide a simple, cheap and effective burner of this character having certain details of structure and combination of parts hereinafter more fully set forth.

Referring now to the accompanying drawings; Figure 1 is a perspective view of my improved burner. Fig. 2 1s a transverse vertical sectional view taken on the line 22, Fig.1. Fig. 3 is a-longitudinal vertical sectional view taken at right angles to Fig. 2, taken on the line 33, Fig. 2. Fig. 4 is an enlarged perspective view of a gas supply tube and the burner supporting base. Fig. 5 is a. perspective view of a shutter for regulating the air to the gas supply tube.

Referring now to the drawings, 1 represents the gas and air supply tube of my improved burner which is of an elongated form and has at its lower end the enlarged outwardly flared air-bell 2, all of which is of the usual construction of burners of this character. The lower end of the air-bell is provided with a beading 3, and opposite Speeification of Letters Patent; Patented June 15 a 1915, Application filed January 21, 1915. Serial No. 3,553.

sitely arranged air-inlet openings 7 by means of which air is supplied to the tube.

Surrounding the cylindrical neck 5 is a cylindrical collar 8, which is provided at its upper end with an outwardly extending annular shutter 9, provided with openings 10 adapted to register with the openings 7. This shutter 9 rests flat against the closure 4 of the air-bell and is rotatably mounted on the neck.

The lower side of the shutter 9 is provided with a rib 11, provided at its outer end with the upwardly extending lug 12, which extends upwardly beyond the beadmg 3, and has passing therethrough a set screw 18, which is adapted to engage the outer face of the flared air-bell 2, beyond the beading 3, and thus the shutter is free to revolve upon the neck 5, but locked against downward movement thereon. By this construction it will be seen that the shutter may be rotated or oscillated so as to bring the openings 10 to register with the openings 7 so that the amount of air passing to the tube 1 is'readily regulated. The set screw 13 is tightened when the shutter has been adjusted to its proper position and thus the proper amount of air is supplied to the tube.

the flange 20 formed therearound and which fits a perforated copper cone 21, which. forms a mixing chamber for breaking up the particles of gas and causing them to thoroughly mix with the air whereby the burner at the point of combustion is supplied with'a properly mixed gas.

The burner head consists of a rectangular body portion 22, which has at its lower end on opposite sides the outwardly flared

walls

23 and 24, which form a. central dome adapted to correspond with the base 14, and is adapted to rest upon the base on the outside of the flange 20 and form a tight joint therewith. The walls and 24 form a domed chamber and at its upper end is a support 25, which is adapted to engage the upper end of the cone and hold it in the depressed portion 19 of the base.' Communicating with the domed chamber on opposite sides are openings 26 and 27 which communicate with the rectangular burner head 22, and whereby the gas after it has become thoroughly mixed with the air after passing through the cone 21, passes to the rectangular burner'22. The dome-shaped chamber formed by the

walls

23 and 24 is provided with outwardly extending

ears

28 and 29 which are arranged directly above the

ears

15 and 16 and are provided with

openings

30 and 31 through which the

bolts

32 and 33 pass.

By this structure it will be seen that the mixing chamber is clamped tightly down upon the circular base 14 and the support engaging the cone, 21 holds the cone in the depressed portion 19against. displacement. The upper end of the rectangular burner head 22 is open as indicated at 3 1 and in which closely fits the distributer head 35.

This head is held in the open top of they burner head 22 by means of a pin .36. The

distributer is preferably formed with a V- shaped groove at the top and has on opposite sides the obliquely arranged

curved grooves

37 and 38 arranged on opposite sides which form passages to allow the escape of gas from the burner head. The gas 'is burned at the outlets of the

grooves

37 and 38.

By this construction and arrangement of parts as herein shown, it will be seen that applicant has produced a burner in which the parts are readily assembled or disassembled, and in which a tight joint is made to prevent the leakage of gas therefrom, and by the arrangement of the copper coneshaped mixing chamber 21, it will be seen that the air and gas is thoroughly .broken up and mixed as it passes therefrom and enters the rectangular burner head 22 in a combustible gas. It thence passes from the rectangular burner head 22 out through the grooves or passages37 and 38 and is burned.

Having thus described my invention what I claim and desire to secure by Letters Patent is:

1. A burner of the character described, comprising a burner head having an open upper end, a distributor head removably secured in the open upper end of the burner head, the lower end of the burner head having a dome-shaped portion, a base having a circular portion closing the lower end 4 of the dome-shaped portion of the burner head and having a combined air and gas supply tube, a perforated cone carried by the circular base portion and extending within the dome-shaped portion of the burner head, and means for fastening the 2 base and burner head together.
