GAS-LAMP.

T 0 all whom it may concern:

Be it known that We, FREDERICK J IIUMPHREY and HUBERT R. HUMPHREY, citi- Zens of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Gas-Lamps, of which the following is a specification.-

This invention relates to improvements in gas lamps.

The main objects of this invention are:

First, to provide in a gas lamp an improved pilot structure in which the pilot is disposed so as to be inclosed and protected by the mantle.

Second, to provide in a gas lamp an improved pilot structure having the above advantages in which the pilot and burner parts are adjustably supported so as to permit the easy assembling or renewal of the parts.

Further objects, and objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims. 5

A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a vertical central section of a gas lamp embodying the features of our invention with certain parts shown in full lines. 1

line corresponding to line 66 of Fig. I, showing details of the pilot support.

Fig.- VII is an. enlarged detail inverted view illustrating the movement of the pilot and the burner tip to bring theminto i proper operative relation, the parts being" shown in full lines in an inoperative posit1on and by dotted llnes in operative position.-

Fig. VIII is grally of the main burner tip. Y

Fig. IX is a section through the burnerof Fig. VIII, ona line corresponding to line 88 of Fig. VIII. 1

In the drawings, similar numerals of reference refer to similar parts throughout the several views, and the sectional views are takenlooking in the direction of the little" arrows at the ends of the section lines.

Referring to the drawing, the gas supply pipe coupling member 1 is provided with a valve designated generally by the numeral 2. As the valve forms no part of our prescoupling member and in the embodiment illustrated comprises a deflector plate 5 which constitutes a support member for the burner, as will appear as the description" proceeds. Above this deflector plate is an air supply casing 6 mounted upon' the tube or collar 7 which is, in turn, threaded upon the coupling member and provided with air inlet openings 8 surrounding the nozzle Y member 4:. The burner mixing tube 9 projects into this tube 7 to receive the air and as. b The air inlet casing 6 is provided with an air inlet opening 10 at its lower end. The

deflector plate 5' has a portion 11 extending beyond the casing 6 and provided with flue dlscharge openings 12, there being, however,

an imperforate portion below the opening 10 to constitute a guard or shield for protecting the. opening 10 from the products of com- 60 a detail side elevation ofa modified form of our improved pilot burner in which the pilot burneris formed in't'e-- bustion. This arrangement is substantially that shown in the application of Alfred H. Humphrey, filed August 9, 1915, Serial Number 44,626.

An upwardly flaring flue member 13 is mounted on the deflector plate to embrace the discharge openings 12 and constitutes a support for the globe 14:. A skirt-like casing member 15 is also mounted on the defiector plate and constitutes a support for the shade or deflector 16. These parts are also substantially as shown in the said application for Letters Patent.

The burner tube 9, which is preferably of earthy material, has external threads 17 with which the collar-like adjusting member 18 is in threaded engagement. This adjusting member 17 has a flange 19 resting on the support member or deflector plate 5, thereby supporting the adjusting member for retative movement. The adjusting member is secured in its adjusted positions by means of the clamping blocks 20, notched at 21 to engage the edges of the flange 19 and clamped thereon by means of the screws 22 arranged through the plate from below so that the screws may be adjusted from below.

The burner 9 is preferably provided with an enlargement 23 at its lower end, inter nally threaded to receive the burner tip 24 which is also formed of earthy material. The burner tip has a shoulder 25 at its upper end and longitudinal ribs 26 terminating in mantle supporting lugs 27, there being spaces between these lugs to permit the mantle supporting rings 28 being slipped longitudinally over the burner tip and then partially rotated to bring its lugs 29 into engagement with the lugs on the burner tip. The mantle 30 is secured to the supporting ring in the customary way.

The pilot burner 31 is supported with its mouth in approximately the plane of the mouth of the burner tip. See Fig. 111. The pilot burner tip is preferably beveled toward its outer side, as shown. With the tip thus supported, it is embraced or inclosed by the mantle. The pilot burner tube 32 is angled and has threaded en agement with a coupling member 33 carried by the support member 5. Thus supported the pilot tube may be swung on its support to its operative position as shown with the pilot burner supported at the side of the main burner or swung away so as to permit the convenient assembling or renewal of parts. The angle of the tube 32 is designed to swing under the enlargement at the lower end the burner tube 9. The shoulder 25 oi the burner tip is provided with groove-like recesses 34: at one side of the ribs 26 to receive the pilot burner tube, permitting the main burner to approximately their proper position and then by rotating them in opposite oirections, they are readily brought to place.

In the modified construction shown in Figs. VIII and IX, the pilot burner 85 is formed in the side of the main burner. The mouth of the pilot burner is positioned in the same relation, iowever, as in the pre ferred construction. The pilot/burner tube 35 is adapted to be engaged with a suitable opening at the upper end of the burner 35. The advantage of rotatlng the burner 1n such a structure will also be appreciated.

The gas is supplied to the pilot through,

the supply tube 36 which is threaded into the coupling member 38 and connected to the supply pipe coupling 1. A regulating valve 37 is provided for the pilot. With the pilot thus arranged, it is as stated inclosed by the mantle so that it is protected thereby and its flame is also covered so that it is not ordinarily visible, when the lamp is ex tinguished. The pilot being thus protected, may be maintained with a low flame and at the same time the flame is so positioned that it immediately lights the gas, thus avoiding explosions which would be likely to blow out the pilot or to fracture the mantle. It is also found that with the burner tube thus positioned, there is no deposit of carbon therefrom on the chimney, aid very satisfactory results are secured.

We have embodied our improvements in lamps of the general structure illustrated. Our improvements are, however, capable of embodiment in various other structures, but as we believe that the disclosure made will enable those skilled in the art to which our invention relates to embody or adapt the same, as may be desired, we have not at tempted to illustrate or describe such embodiments or modification.
