BURNER.

SPECIFICATION forming part of Letters Patent No. 731,392, dated June 1 1903.

Application filed May 28,1902- To all whom, it may concern.-

Be it known that we, TOWNSEND STITEs, residing at Gloucester City, in the county of Camden and State of NewJersey, and JOHN H. G085 and ALFRED J. WOLFE, residing at Waterbury, in the county of New Haven and State of Connecticut, citizens of the United States, have jointly invented a new and useful Burner, of which the following is a specification.

One object of the present invention is to provide an attractive, sightly, and eflicient burner or fixture of the type recited in which free access can be had to the light-emitting elements or mantles and in which an eflicient support is provided for the globe.

Another object of the present invention is to provide globe-holding devices which remain eflicient in use and are not deleteriously afiected by heat.

Another object of the invention is to pro-1 vide for the convenient renewal of the parts.

Other objects of the invention will appear from the following description.

Stated in general terms,the invention com prises the improvements hereinafter described and claimed.

The nature, characteristic features, and scope of the invention will be more fully understood from the following descriptiomtaken in connection with the accompanying drawings, forming part hereof, and in which- Figure 1 is a View, partly in section and partly in side elevation, of an arc-light gasburner embodying features of theinvention. Fig. 2 is a sectional view taken on the line 2. 2 of Fig. 1. Fig. 3 is a sectional view taken on the line 3 3 of Fig. 1. Fig. 4 isa view illustrating a detail of construction of the; globe-holder. Fig. 5 is a plan view of a part; of the globe-support, and Fig. 6 is a sectional view drawn to an enlarged scale and illustrating in central section the ball-andsocket Serial No. 109,388. (No model.)

ling 4, so that the part3 can be detached from the coupling 4. As shown, the coupling 4 has screw-and-thread connection with the pipes 3and 1 and is clamped to the part 1 by means of a set-screw 5. At the lower end of the part 3 of the pipe is secured a cluster-fitting 6. As shown, this cluster-fitting 6 is screwed onto the pipe 3 and held to place against accidental unscrewing by a clampscrew 7. The cluster-fitting o is provided with several burner-fittings 8, of which four are shown in the drawings and of which the "number may be increased or diminished.

The clusterfitting is also provided with a seat for the plug 9 of the valve and above this seat with a by-pass opening 10 to a pilotlight tube 11.

12 represents means for operating the plug 9 to turn the supply of gas onto and off from the burners 8. 3

The by-pass 1O permits the pilot-light 11 to burn continuously. The pilot-light tube 11 is supported by a strap a, encircling it and the pipe 3 and clamped together, as at b, and held to place by a set-screw c. As shown, the burners S'are fitted with Welsbach or other incandescent mantles and are of the Bunsen type. Depending'from the baseof the cluster-fitting is a stud having its shank partially squared for engagement with the bottom piece 13 of the globeesupport shown in Fig. 5. This bottom piece 13 is detachably held to place bya screw or bolt 14, which may be connected, as by a chain and swivel 15,.with the cluster-fitting, so that when the bolt is unscrewed it is not likely to be lost or dropped. From the bottom piece 13 radiate arms 16, of which four are shown and which carry at their upper ends a flanged ring 17, to which they may be riveted. The parts 13, 16, and 17 constitute a globe-support ring adapted to receive and support the neck of the globe 18. I X

Upon the gas-pipe 1 there is mounted so as to slide up and down a carrier or sleeve 19. Onto the lower end of this sleeve is-secured a spider 20, consisting, as shown, of athreaded ring having arms radially screwed into it, which arms are upturned at their free ends. The spider carries the hood 22, which consists of an open cylindrical shell and which may be riveted to the upturned arms by the same screws or rivets which connect the holders 23 for the shade 24, when present. The shell 22 is provided at its base with a flaring skirt 25, which surrounds and rests on the globe. The globe-holders 26 consist of what may be termed pig-tail springs secured or riveted to the side wallof the hood 22 and having their free ends bent to take into the groove at the top of the globe 18. The free ends of these springs tend to lie against or approach the Walls of the shell, and the setscrews 27 serve to hold them in position for supporting or holding the globe. By this construction the screws 27 really carry the weight up the globe 18, although the latter is normally supported from its base in the manner described. The upper end of the sleeve 19 is provided with a bayonet-joint 28, made by pressing outward its walls, as shown in Fig.

4 3. In fact, there are shown two such bayonetjoint members diametrically opposite each other, and they cooperate with pins 29, projecting radially from the pipe 1.

In use and in order to obtain access to the lights the sleeve 19 is shifted upward and its bayonet-joint members 28 are brought into ongagement with the pins 29, so that itis locked in elevated position. In rising the sleeve car ries up with it the hood 22 and the shade 24, when present. The globe-holders 26 by engaging with the flange at the top of the globe lift it from its support-ring 17, and in this way free access can be had to the burners, and, if necessary, they can be detached at the coupling 4 or 7. When the parts are to be returned to their normal positions, the bayonet-catch is disconnected and the sleeve and its parts are'lowered, with the result that the globe 18 is returned to its globe-support ring 17 and the hood 22 and shade 23, when present, are supported by the skirt 25, which rests on the top of the globe 18. The globe .18 may be completely removed and replaced screws 27 are then turned so as to bring the holders 26 into position for engaging the flange at the top of the globe.

It will be obvious to those skilled in the art to which the invention appertains that modifications may be made in detail without departing from the spirit thereof. Hence we do not limit ourselves to the precise construction and arrangement of parts hereinabove set forth, and illustrated in the accompanying drawings; but,

Having thus described the nature and objects of our invention, what we claim as new, and desire to secure by Letters Patent, is

1. Aburnercomprisingagas-pipe provided at its base with a cluster-burner and with a globe-support, a tubular sleeve slidably encircling said pipe, a hood carried by the sleeve, globe-holders carried by the hood, a globe normally seated on the support and arranged to be lifted by the holders to afford access to the burners, and means for supporting the sleeve in elevated position, substantially as described.

2. A burner comprising a gas-pipe fitted at its base with a cluster-burner and with a globe-support and at its upper part with a radially-projecting'pin, a tubular sleeve slidably encircling said pipe and provided at its upper part with a bayonet-joint member, a hood carried by the sleeve, globe-holders carried by the hood, and a globe normally seated on said support and adapted to be lifted by the holders, substantially as described.

3. In a burner the combination of a globe, a gas-pipe provided with means for holding the globe, a hood slidably mounted on the gas-pipe and provided with a skirt adapted to rest on the globe, and a ball-and-socket joint for supporting the gas-pipe in vertical positions whereby the skirt bears evenly on the globe, substantially as described.

4. In a burner the combination of a gaspipe provided at its base with a globe-support, a globe normally seated on said support and provided with a flanged top, a carrier slidable on said pipe, a hood connected with the carrier and provided with a skirt adapted to rest on the globe, and spring globe-holders and their complemental set-screws, substantially as described.

5. In a burner the combination of a spider provided with arms having upturned ends, a hood mounted outside of the upturned ends, shade-holders arranged outside of the hood and opposite the upturned ends, and fastening devices engaging the holders and the upturned ends and penetrating the Wall of the hood and serving to clamp it between the upturned ends and the holders, substantially as described.

In testimony whereof we have hereunto signed our names.
