- rality of inverted burners. Second, to provide an improved gas lamp having inverted burners in which all the parts are readily ac cessiblc so that it is not necessary to disassemble the lamp for the purpose of adjusting or arranging the parts. Third, to provide, n a gas lamp, an improved valve construction.

ourth, to provide, in a gas lamp, an improved 'pilotlight construction. Fifth, to provide, in a gas lamp, an improved construction and arrangement of the burners.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my inv'ention by thedevicesand means described in the following specification.

The invention is clearly defined and pointed out in the claims. v I

A structure embod 'ing the features of my invention is clearly il ustrated in the accompanying drawing, forming a part of this specification, in which,- 1

Figure 1 is an elevation of a structure cmbodying the features of my invention, the deflector-plate, casing, reflector and globe being sectioned on a line corresponding to line 1j1 of Fig. 2. Fig. 2 is a vertical section taken on a line corres onding to the broken line 22 of Fig. 1. i 3 is a vertical section of a slightly modified construction, taken on a line corresponding to line 3-3 of Fig. 4, the structure here being adapted to two burners instcag of to a number of burners, as shown .in igs. 1 and 2. Fig. 4 is a vertical section taken on a line corresponding to line 4-4 of Fig. 3. Fig. 5 is a, horizontal section taken on a line corresponding to line 55 of Fig. f1. Fig.6 is a pan view of the mantlesupporting-plate, one of the mantle-holders being shown in position therein. Fig. 7 is a detailsection taken on a line corresponding to line 7- 7 of Fig. 6. 1 Fig. 8 is a detail section taken on a. line corresponding to line 8-8 of Fig. 6. Fig.

9 is an enlarged detail vertical section taken on a line corresponding to line 99of Fig. 3. In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar reference characters refer to similar parts throughout the several views.

Referring to the drawing, 1 represents the as supply pipe which is, in the structure illustrated, also designed as the support for the lamp. At the lower end of the supply pipe is a valve 2. Projcctin upwardly from this valve is a T-shaped do 'very pipe. In the structure illustrated in lrigs. 1 and 2, the

gas delivery pipe, section 3 is connected to V the valve by the upwardly projecting pipe section 4, the delivery pipe section being arranged in a horizontal position and havin a plurality of burners connected thereto, t e structure illustrated having six burners arranged in a straight line.

The burner nipples 6 are connected to the delivery pipe 3 by means of the hollow arms 7. Theburner nipples are provided with suitable delivery nozzles S which are controlled by the needle valves 9. Upon the nipples are threaded tubular. valve sections 10 having suitable air ports therein. These air ports are re ulated by the valves 11 which are three ed upon the sections 10.

The burner tubes 12 are arranged through the openings 17 in the flange 16 at the bottom of the chimney 15. The burner tubes are-provided with suitable threads 13 so that they may be threaded through the flu e and are there 3' supported, the-upper on s of the tubes projecting into the valve sections 10. The flange 16 of the chimney p'rojccts to one side thereof and is provided with a substantially horizontal portion lll1f0lll which the burner tubes are arran ed. y

arranging the chimney at one si e of the lam p,1the burners are centered therein. The

burner tips 14 are located below the flange and the chimnc' serves to conduct the pro- ;iucts of combustion and heated gases thererom.

By locating the chimney at one side, the burners are properl centered in the structure, as. stated, so t at, where the structure has a plurality of burners, as illustrated in Fig. 1, they may be arranged in a row, like .wise where a sin le burner is "so ,The flange of the chimney is flared downwardly, so that it effectively gathers the products of combustion and conveys them to ney, in structures having a number of burnwrapped around the chimney, as shown in thereon.

' thereof.

adapted to engage this wide to limit the the chimney, and also causes the draft of I fresh air to the burner to insure proper com- E bustion. This arrangement also protects the air inlets or ports for the burner tubes from the products of combustion. so that pure air is mixed with the gas. The chimers arranged in a straight line, as shown in Figs. 1 and 2 is preferabl flat and is preferab y supported by the strip 18, which is Tn the construction shown in Figs. 3, 4 and 5, the supply pipe is offset by a right angled coupling and the chimney is supported by the rod 19 dependingfrom the coupling. A clip 20 secures the upper end of the chimney to this rod, preventing the same from tilting on the rod.

The mantles are supported below the burner-tips by the plate-like mantle-support 21. This mantle-support also serves as a reflector-plate. The mantle-support is preferably provided with an upwardly proecting flange 22 at its rim, the flange being adapted to fit within the flange of the chimney'. The' mantle-supporting plate 21 is provided with openings having upwardly projecting flanges about the same. The mantle-holders are preferably in the form of rings 24 having laterally projecting arms 25 The fianges23 about the openings are provided with notches 23 adapted to receive these arms whereby the turning of the holders in the support is prevented, the mantle-holders being dropped into place from. the top of the support. In' order to conveniently permit of this, the mantle-support is supported by the rod 27 which is arranged through the flange on the chimney and through a suitable guide 28 on the side On the upper end of the rod 27 is a head 30 downward movement of t 1e rod. When the mantle-support is in its lower position, it may be swung to one side from under the burners. It is held in its upper position by the button 29, the structure being similar and, in some respects, an improvement upon the mantle-support shown in my application l for Letters Patent of the United States, tiled l on June 26th, 1906, Serial No. 322,.s90. The l mantles 26 are secured to the holders 24 in an suitable manner. l

n tho structure shown in Figs. 1 and 2, I provide a reflector shade, the some being rectangular in form and having its walls set at an angle. This shade is preferably formed l of mirrorspso that the light is reflected very effectively, being particularly effective in a 5 structure havi burners arranged in alinei ment, as shown in Figs. 1 and 2. The globe 35 is preferably suspended from the upper l edge of the re ctor. The reflector is supl The c )imney, burner tubes and valves are preferably surrounded with the ca'sin 36,

the same being arranged to rest on the i ange of the chimney, so that it may be lifted, .when it is desired to manipulate or adjust the alves for the burners.

The main valve for the supply ipe projects through this casing, a suitab e slot 37 being provided therefor. The deflectorplate 38 is loosely mounted on the gas supply pipe, so that it ma be moved up and down thereon, a suitabe collar 39 limiting its downward movement and holding it sup ported above the upper end of the casing and chimney to permit a free escape of the heated gases therefrom.

In the modified, or twoburner construction, the globe 44 is secured to a suitable globe-supporting ring 40, which is hinged to the projecting arm 41 at one side. Opposite the arm 41 is an arm 42 carrying a thumbserew 43 by means of which the globe-supporting ring is secured. These arms 41 and 42 are carried by the upwardly flaring band 45 mounted on the flange of the cluinney.

The casing 45 in this construction is preferably provided with a downwardly llarin'g flange 46, the lower edge of which, when in its lower position, projects over the band 45; This casing is arranged practically the same as the casing 36 described and is adapted to be lifted to allord access to the burner valves.

The valve casing 2 is provided with

pussages

48, 49 and 50, the passage 48 being connected to the gas snpplypipe; the passage 4!) to the pipe 4; and the passage 50 to the pilot burner. The valve 53 is provided with a main passage 54 adapted, when the valve is open, to connect the

passages

48 and 49 thereof, thereby admitting the gas to the dclivery pipe and thencev to the burners. The passage 55 is so arranged as to open into the passage 50 when the main valve is o )0", thereby admitting gas to the pilot to llash the same. The pilot 46 is connected to the passage 50, as clearly appears in Fig. 5. he passage 50 is connected to the passage 48 in the valve casing by a by-pass 5]. This bypass is controllml by a needle-valve 52 adapted to regulate the constant supply of gas to the pilot. The pilot light tip 47 is arranged throu h the flange of the chimney and is laterally directed to shoot the flame across is ofadvantage when the lamp is extinguished. With the mantle-support shown it 10 is entirely closed and protector although it is uite effectively protected without this.

have illustrated and described my imroved gas lamp in detail in the form preerred by meon account of the structural simplicity and convenience with which it may be cared for in use, the parts being all easily accessible. I am aware, however, that it s capable of considerable variation in structural details without departing from my invention, and I desire to be understood as claiming the same specifically, as illustrated, as well as broadly.
