GAS-BURNING HEATER.
SPECIFICATION forming part of Letters Patent No. 744,283, dated November 17, 1903.
Application filed J'nly 1'7, 1903. Serial No. 165,899. (No model.)
To aZZ whom it may concern.- I
Be it known that I, LEWIS F. BETTS, a citizen of the United States, residing in the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Gas-Burning Heaters, of which the following is a specification.
The invention. relates to heaters arranged to serve with the usual illuminating-jet outlets in the gas-supply pipes; and the object of the invention is to provide an apparatus which shall have great radiating-surface and a burner therefor which will produce the required heat and also afford brilliant illumination and which shall be easily and cheaply manufactured and be neat and attractive in appearance.
The invention consists in certain novel arrangements of parts and details of construction by which the above objects are attained, to be hereinafter described.
The accompanying drawings form a part of this specification and show a preferred form of the invention.
Figure 1 is a side elevation of the heater. Fig. 2 is acorresponding diametrical section. Fig. 3 is a View of the under face of the radiator portion, and Fig. 4 is a plan or top view of the burner portion. Fig. 5 is a vertical section showing aportion of Fig. 2 on a larger scale. Fig. 6 is a similar view of an other portion of the same figure.
Similar letters of reference indicate the same parts in all the figures. I
Gas from the service-pipe (not shown) is received by the nipple A, adapted'to be screwed upon an ordinary illuminating-jet outlet, and, passing through a tube or cone A of wire-gauze or other desired. equalizing distributor fills the interior of the gas-chamber A secured to the nipple A. The gas-chamber may be of any desired form. I have shown it as having a dome-shaped upper portion having a central exteriorly-screw-threaded boss A and an annular shoulder A below which is a horizontal annular rim or deck A in which is a series of equally-spaced small holes a a, through which gas from the interior of the chamber issues and is burned in a series of vertical jets. The lower portion of the chamber curves inwardly and downwardly and terminates in an upwardlyextending tube A within the chamber, screwthreaded to match to the nipple A.
It is important in attaining the best heating results that there be as many jets as practicable, and it is also important in effecting the desired complete combustion that each jet maintains its individuality and does not mingle with the next in the series. These essential features are secured by properly spacing the jet-holes, and the free combustion desired is further insured by the employment of a cap B, applied on the upper portion of the gas-chamber and having a hole matching to the boss A serving to hold the cap concentrically thereon. The cap has an annular flange B at the level of the shoulder A extending beyond the deck A and having an annular skirt or depending lip B reaching a little below the level of the deck and encircling the latter with a slight air-space between. The flange B is pierced with a series 'of openings 1), one for each jet-hole a and exactlyconcentric thereto, the desired position being determined and insured by matching an aperture b in the flange with a swell or .boss A produced in the deck for the purpose.
Each jet is thus supplied with the required volume of air delivered uniformly around the jet, and when the parts have become heated the air thus supplied is warm and in the best condition to insure perfect combustion and produce an' extremely brilliant white flame. I prefer to produce the holes a by punching in suitable dies, for the reason that greater uniformity may be thus attained than by drilling, and by making all the jet-holes of exactly the same diameter and supplying the same amount of air to each jet all burn uniformly and attain a uniform height or length of jet.
Upon the boss A is screwed the lower end of a short tube or standard 0, locking the cap B beneath it-and having a bead or narrow flange 0, upon which rests an inverted bell 0 serving as a flame-spreader and preventing the jets from curving inwardly and mingling at their upper ends. Screwed into the upper end of the standard 0 is a short nipple D, formed on an inverted cap D, attached to and forming part of the hood or radiator E, thus supported above the jets and receiving heat therefrom.
The radiator is circular and of considerably larger diameter than the cap B and is,'in effect, a hollow shell of sheet metal comprising two main portions spun to the forms shown in the drawings,one, the top E, being flat on the upper face, excepting as stiffened by the annular interior beads e e formed therein, the latter, e serving also to hold the inverted cap D by being forced over and locked beneath the flange D thereon. The top E has a slightly-flared depending flange E secured by a lapped joint to an oppositelyflared flange E on a second portion of the radiator, serving as a reflector. This portion comprises an inwardly and upwardly extending truncated cone E open at the upper end and formed in one with the flange E The under face of the cone serves as a reflector for the heat and light from the jets below and may be whitened or otherwise treated to produce the desired reflecting-surface. I prefer to use for this purpose asheet of white asbestos paper M, cut to match the under face of the cone and having its lower edge received in a trough-like fold E of the metal at the junction of the cone and flange E the upper edge, lying within a downward fold E at the upper margin of the cone, equipped with short lugs E adapted to be bent downwardly to hold the asbestos in place.
The opening at the top of the cone is large enough to allow the upper ends of the jets to enter instead of striking directly upon the reflector, and the cone reaches nearly to the under face of the top E, leaving a narrow annular space sufficient for a slight circulation of air within the radiator, the holes 6 permitting the slow escape of products of combustion and preventing the collection of dead air.
It will be noted that nearly all the parts are of sheet metal spun or shaped in suitable dies to the desired forms and that soldered and riveted joints are avoided, thus permitting the heater to be cheaply manufactured, and by joining the burner to the radiator by the threaded standard 0 the parts may be packed in the knocked-down condition in small compass for shipment and be easily set up for use.
The heater presents a large area of radiating-surface exposed directly to the circle of jets, and the arrangement of the latter with the air and gas-supply thereto insures brilliant illumination, aided by the effect of the reflector, and the whole forms an efficient heater combined with an illuminating-burner adapted to serve on a drop light stand, bracket, or chandelier.
Modifications may be made in the forms and proportions within wide limits withoutdeparting from the invention.
Other material may be substituted for the asbestos as a reflecting-surface, or the under face of the cone may be enameled or otherwise coated to produce the desired effect.
I claim- 1. In a gas-burning heater, a gas-chamber having an annularly-arranged series of jetholes equally spaced apart and separated to insure independent burning-jets, a cap over said holes and having coincident larger openings, a flame-spreader above and separated from said gas-chamber, and a radiator supported above the flame-spreader.
