SPECIFICATION forming part of Letters Patent 0. 714,444, dated November 25, 1902.
Application filed December 18,1901. Serial No. 86,380. (No model.)
To all whom it may concern: connection-with a hollow member O, having Be it known that I, TOM BRABSON, a citizen branches D preferably separated from each of the United States, residing in the borough other, so as to avoid as much as possible any of Brooklyn, county of Kings, city and State obstruction to the admissionof air from beof New York,"have invented certain new and low.

A button M or hantheir lower ends. dle of any sort is attached to the end of the My improvements are illustrated as applied operating-rodL, and by turning this the valve 75 to a multiple burner, such as is commonly is moved upward, so that its upper facebears used in shops or other public places for givagainst the seat E to cut off the supply or is ing a large quantity of light. In such places moved downward into the chamber F to adit is generallyvery desirable or even necesmit a full supply to the branches and so that sary to save head-room by making the entire its lower face bears against the packing-ring 8o lamp as short as possible. By a very com- J to prevent escape of gas along the rod. pact arrangement of the supply-pipe and the Under the intense heat to which the central individual burners and the operating parts supply-pipe is exposed there is sometimes a I have succeeded in producing an extremely considerable formation of scale within the 1 3 5 short lamp. According to the preferred arpipe, which drops into the valves as pre- 85 rangement theimain supply-pipe A of my viously constructed. There is also a certain lamp is arranged centrally of-a group-comamount of solid matter in the gas. These prisingin the present case four-of individual and possibly other foreign matters often clog burners B. I preferably extend the main the valves of supply-pipes after the lamps o supply-pipe A downward from any suitable have been in use for a time. In connection 0 point of support and connect the'individual with my improved valve I use a spider N, burners therewith by branches radiating from which moves in the port of the valve as the its lower end, so that it does not extend belatter is operated, as indicated by the dotted low the lamp at all. The valve for cutting lines in Fig. 2. When the valve is operated off or turning on the supply may be convenin the manner explained, the spider end not 95 iently located immediately at the lower end only reciprocates in the port, but rotates of the supply-pipe and preferably has a short therein also, and the sharp edges thereof keep downwardlyextending operatingrod. As the port entirely clear of dirt. Any foreign illustrated, the supply-pipe A is connected matter passing down into the branches D or at its lower end-as, for example, bya screw the chambers F and K can be quickly re- Ioo moved by unscrewing the member II. This construction is therefore not only compact and simple and therefore cheap, but is most convenient in the keeping of the lamp in good order. I preferably also screw a nut O on the tubular extension of the nut H. A washer O prevents leakage in intermediate positions. It is to be noted also that with the valve arranged at a point considerably below the mantles and directly in the path of the cool air which is admitted to the lamp I avoid excessive heating of the valve, which has been a frequent cause of injury in previous constructions in which the valve is located higher up in the supply-pipe and nearer to the mantles.
Ipreferably use a continually-lighted pilotjet P, comprising a vertically-arranged pipe connected in any suitable way with the supply-pipe A, and I add to the convenience of control of my burner by providing the valve Q thereof with an operating-rod R, extending downward, as indicated in Fig. 2, to a point below the burner, so as to be convenientof operation at alltimes. I have also improved the means of holding the shade or globe which surrounds the burner by the use of shade-holders S, which are movably connected to the several branches D, whereby they can be moved outward to support the shade or inward to pass within the opening of the shade as it is put in place or removed. These shade-holders are preferably single arms having upward extensions at their outer ends and pivoted at their inner ends on the under sides of the several branches D by means of a pivot T, screwing into a boss U, formed on the under side of the branch for this purpose. This forms a very simple connection, and the parts are so proportioned that the holders S when swung horizontally inward occupy the very compact position shown in dotted lines in Fig. 3 and when swung outward extend outside of the shade, so as to support the same, as illustrated in Fig. 2. As indicated in Fig. 3, the lower part of the burner when in actual use with the shade in place comprises onlya series of narrow arms radiating from the center and presenting the least possible resist-' ance to the admission of air from below. The supporting of the mantle is also accomplished in a very simple and durable manner in my improved lamp. For this purpose I preferably provide a support attached directly to the central downwardly-extending supplypipe at a point above the mantles and adj ustable in height on such pipe. From this support I suspend hooks, which have their lower ends adapted to engage the mantles. The mantle-support V is preferably a casting fitting loosely over the pipe and adjusted and held in position by means of a set-screw \/V and having arms X extending toward the several mantles. Each of these arms has a vertical aperture Y, and each of the hooks Z has a bend a at its upper end adapted to pass downward into the aperture Y. Preferably also each arm X hasa radial notch 12 in its end, in which the shank of the hook Z rests so as to prevent lateral movement thereof. The heat to which such a mantle-holderis subjected and the expansion and contraction of the metal often result in a loosening of the connection of the holder with the supply-pipe, and after the lamp has been in use for some time the mantle-holder slips on the pipe and breaks the mantles. In order to certainly avoid this trouble, I provide in connection with mantlesupports of this general type a fixed stop on the pipe whose upper edge is in contact with or immediately below the mantle-support and which, in case of the accidental loosening of the support, prevents the same from falling far enough to injure the mantles. This fixed stop may be very simply made in the form of a sleeve 0, whose lower edge rests on the horizontal branch of the pilot-burner or on any other fixed point of the burner and whose upper edge is close to the lower edge of the mantle-support V. I also provide certain improvements in detail in the individual mixing-tubes of the several burners,whereby their construction is cheapened and strength ened and the operation improved. To stand the intense heat which occurs, these tubes must he made of considerable solidity, and I make them, preferably, of a single tube (31. of cast brass, in the lower end of which is fitted a gas-nozzle e, which in turn is connected to the upwardly-extending portion of the branch D. The lower end f of the tube which constitutes the chamber in which the nozzle 6 is placed is somewhat enlarged, and openings at the side for admission of air are formed by a straight out directly across the side of the tube, as indicated at the left of Fig. 1. vides space for the admission of ample air. The upper end of the tube is enlarged, as shown at g, and a sheet of wire-gauze or the like h is held on the top thereof by means of a cap j. In order to press the flame outward against the mantle 7:, I preferably use a spreader, which is connected to the center of the sheet of gauze h and extends downwardly therefrom, so as to spread the combustible mixture outward. The spreader is durably and cheaply constructed and connected to the gauze in the following manner: A plate Z of the desired diameter is pressed against the underside of the gauze by means of a shoulder on a tube m, the upper end of which tube is extended through the gauze and swaged outward at its outer end, preferably over a washer 12.
Though I have described with great particularity of detail a lamp embodying my invention, yet it is to be understood that my invention is not limited to the specific device shown and described.
Various modifications in the details and in the arrangement and combination of parts One of these cuts on each side promay be made without departure from the invention.
What I claim is 1. In an incandescentgas-burner, the comattached to the upper part of said pipe, and.
a fixed stop held on said pipe with its upper edge immediately below the mantle-support whereby to prevent said support from falling, said fixed stop comprisinga'sleeve surrounding said supply-pipe and supported on one of said branches.
2. In an incandescent gas-burner, the combination with a downwardly-extending supply-pipe, of branches connected to the lower part of said supply-pipe, a mantle-support fitting around the upper part of said pipe and adjustable in height thereon, and a fixed stop held on said pipe with its upper edge immediately below the mantle-support whereby to prevent said support from falling.
3. In an incandescent gas-burner, the combination with a downwardly-extending supply-pipe, of branches connected to the lower part of said supply-pipe, a mantle-support on the upper part of said pipe, and a stop fixed on said pipe at a point thereof above said branches and in position to prevent said support from falling, said stop comprisingasleeve surrounding said supply-pipe and supported on one of said branches.
4. In an incandescent gas-burner, the combination with a mantle-support V having an arm X extending over the mantle and having a vertical aperture Y, of a hook Z having its lower end adapted to engage a mantle and having a bent portion aat its upper end passing downward into said aperture.
