GAS-BURNER.
SPECIFICATION forming part of Letters Patent No. 379,046, dated March 6, 1888. Application filed March 29, 1887. Serial N o. 232,875. (No model.)
To all whom it may concern.-
Be it known that I, HENRY A. BEOGNARD, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Gas-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to that class of lamps wherein the heat of the products of combustion from the iiame is imparted to the airsupply and to the combustible gas for increasing the illuminating power of the dame; andit consists in certain improvements in the construction of the regenerative gas-burner for which Letters Patent of the United States have been granted to Charles M. Lungren on the 24th day of June, 1884. In these lamps, asheretofore constructed, the burner, which is screwed upon the lower end of the gas-supply pipe, consists of a chamber provided with a number of tubes which project downward therefrom and terminate in a perforated aunulus. These tubes are arranged at such a distance apart as to allow the air to circulate freely between them concentrically about a rod which is provided at its lower end with a perforated defiector or button.
The object of my present improvement is to make the deflector and perforated diaphragm of the burner of one solid piece of metal, for the purpose of reducing the cost of manufacture and obviating the destructive effects of expansion and contraction arising from the extremes of heat and cold to which the parts are subjected.
In the accompanying drawings, Figure l is a vertical section illustrating the application of my improvement to a lamp of known construction. Fig. 2 is an enlarged view of the burner, partly in section; and Fig. 3 is a plan view of the same.
The burner, which is screwed upon the lower end of the gas-supply pipe E, consists of a chamber, D, provided with a number of tubes, d, which project downward therefrom and terminate in a perforated annulus, d. The tubes are arranged at such a distance apart as to allow the air to circulate freely between them concentrically about the rod H, which is provided at its lower end with a deiector-button, I. The tubes are surrounded by a sheet-metal cylinder, A, which has its lower end turned outward in such a manner as to form an annular flange, a, which supports the outer edge of the diaphragm B. The part of the diaphragm B extending from the outer edge of the perforations b to the outer edge of the flange a takes the place of the separate flame-plate which has heretofore been used, and thus the perforated diaphragm, which has been heretofore placed in the airpassage between the burnertubes and the cylinder surrounding them and the detlector, is formed of one and the same piece of metal.
In the lamp described in English Patent No. 14,335, of November, 1886, a thick castiron flame plate or deiiector is used in combi nation with a diaphragm; but it has been found that this construction is defective, because the thick casteiron dame-plate absorbs a large amount of heat, which absorption causes it to grow and become distorted, and also causes the disintegration of the washer to which it is attached and the overheating of the gas-tubes which it surrounds.A It is also to Abe observed that in this lamp no provision is iliade for the expansion and contraction occasioned by change of temperature, and the parts were therefore liable to become distorted and in jured. These objections are obviated by male ing the perforated diaphragm and flame-plate of the precise form required of a single piece of sheet metal having an annular recess for the reception of Athe annular projection or :flange a upon the cylinder A and a cylindrical projection which rests loosely against the ring d.
Having thus described my invention, I claim and desire to secure by Letters Patent- In a regenerative gasburner, the combination of a perforated annulus, d', at the lower 9 end of the gas-tubes, a cylinder, A, provided with an annular flange, a, surrounding the burner, and a sheet-metal ring having its inner edge turned up to form a cylinder which slips loosely over the annulus d', and its outer part bent downward and thenvupward to serve as a flame plate or deflector, and also to form an annular recess for the reception of the flange c.
In testimony whereof I have affixed my signature in presence of two witnesses.
