GAS-LAMP.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed June 6, 1907. Serial No. 377,651.

To all whom it may concern.-

Be it known that I, ALFRED H. HUMPHREY, a citizen of the UnitedStates, residing at the city of New York, county of New York, State of New York, 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.

It relatesparticularly to improvements in gas lamps of the inverted burner type, such as are shown and described in United States Letters Patent issued to me on January 15th, 1907, No. 841,323, and my application for Letters Patent filed May 15, 1907, Serial No. 373,823, and is a modification of and in some respects an improvement and an adaptation of the structures there illustrated.

The main objects of this invention are: first: to provide an'improved gas lamp which is so constructed and arranged that the parts above the inverted burners are prevented from becoming heated to an undue extent; second: to provide an improved gas lamp of the inverted type which is very efficient and at the same time comparatively economical in structure; third:

' to provide an improved gas lamp having inverted burners in which the parts requiring adjustment or regulation or other care in the operation of the lamp are readily accessible.

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

I accomplish the objects of my invention by the devices and means described in the following specification. v

The invention is clearly defined and pointed out in the claims. 4

A structule embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a central vertical section of a gas lamp "embodying the features of my invention, the gas delivery pipe, the valve casing and the burners being shown in full lines; Fig. 2 is a horizontal section taken on a line corresponding toline 2-2 of Fig. 1; Fig. 3 is a detail end elevation of the valve mechanism, look ing from the left of Figs. 1 and 2; Fig. 4 is an enlarged section through the valve casing and valves taken on a line corresponding to line 4-4 of Fig. 3; and Fig. 5 is a detail section taken on a line corresponding to line E -5 of Fig. 4.

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

coupling at its lower end, to which the pipe sectionsfS straps 13, which are formed on the rim 1.2 thereof.

and 3are connected, the pipe section 3 being a dummy. At the lower end of the gas delivery pipe is a valve casing 4, which controls the delivery of gas to the gas delivery ring 6, this gas delivery ring being connected to the valve casing by the short section 5.

The chimney 7 is preferably supported from the gas delivery pipe, being connected thereto by straps 8, suitable collars as 9 being provided onthe pipe for holding the straps in position thereon. At the lower end of the chimney is an outwardly-projecting. flange or deflector plate 10. This deflector plate is preferably provided with a downwardly-projecting flange-like rim 11-at its outer edge, and is also preferably providedwith an upwardly-projecting flange-like rim 12 about its central opening. This rim 12 projects into the lower end of the chimney. The flange or deflector 10 is prefer ably connected to the chimney and supported by the The deflector plate and chimney are so arranged as to provide for the passage of air from above the plate into the chimney. l

The burners 14 are arranged through-the flange or deflector platelO, substantially as shown and described in my patent above referred to. 'The burner tips 15 are arranged below the chimney flange deflector plate and within the downwardly-projecting rim thereof. The mantles 16 therefor are preferably supported by the plate-like mantle holder 17, which is adjustably supported by the rod 18. This rod is held adjustably in position by the sleeve 19. As this mantle supporting plate and the adjustable support therefor form'no part of this invention, I do not describe the same in detail herein.

The outer casing of my improved lamp is preferably made up of an upper section 20 and a base section 21, the sections being arranged to telescope on each other when it is desired to secure access to the burner valves or the partsof the burners above the deflector plate. The. upper section 20 of the outer casing is preferably suspended from the deflector 22 by means of suitable straps as 23. The outer casing is open at its upper end for the outlet of the products of combustion and the heated air, the same passing out from under the deflector 22. The outer casing is preferably perforated or provided with suitable inlets as 24 at its lower end for the admission of air to the burners and also to cause a circulation through the outer casing for its properventilation, and for the coolingofthe parts-above the deflector plate. A portion of the air passing through these openings passes to the air ports of the burners to secure the proper burn-ing minture; and a portion is caused by the draft of the chimney toflpass downwardly into the base of the chimney. This air, passing over or across theburners, cools the same in an effective manner. A portion also of this incom ng air is caused to circulate up through the outer casing outside oithe draft chimney, thus effectively ventilating it and cool- I ing-the parts of the lamp. The lower sectionoi the plate or chimney flange 10 and is supported thereby.

The outer casing is slotted at 4a to receive the valve casing 4 The globe; as 46, is supported by the globesupporting band 26, which is provided with an out wardly projecting hinge member 27. The hinge member 27 on the globe supporting band is secured .to the downwardly-projecting hinge member 28 on the valve casing i by means of the pivot 29. The globe supporting band is held in its closed position by means of the A structure it is sometimes desirable that only one of the burners should be in operation. To accomplish .this I provide one of the burners 14 with a by-pass or independent connection to the valve, I preferably accornplish this by securing the delivery pipe 'section 32 to the gas delivery ring 6 by means of the threaded plug 33, it being threaded into the ring 6 and also into the section 32, as clearly appears in Fig. 2. This section 32 is connected by the tube or pipe 34 to the valve casing. The valve 35, which is of the rotary or globe type, is provided with two ports as 38 and 39; the port 38 being adapted to control the delivery of the gas to the gas delivery ring 6, and the port 39 to the delivery pipe 34. The valveport 39 is made longer than the port 38, so that after the valve has been moved far enough-to close the port 38, the port 39 still remains open, as is indicated in Fig. 5. This cuts off the gas from all ex-' cepting one burner 14, and on further rotht'ion oi the valve the gas is cut off from this burner. These ports 38 and 39 are preferably arranged side by side in the valve, the passage 40 in the valve casing having an extension 41 at one side to connect it to the port 39. The valve 35 is preferably provided with a cross arm 36 on its stem, to which the operating chains, as 37 and 37 are connected. To indicate to the operator when the valve is in position to supply'gas to the individual burner only, I provide the valve-stem with a.

spring stop pin'adapted to engage the arm 51 when the valve is in position to admit gas to the individual burner. On the continued pull on the operating chain,

. the stop yields sufficiently to pass under the arm, sub;

stantially the same as shown in U. S. Letters Patent, No. 722,306, issued to me on March 10, 1903.

The pilot light 42 is controlled by the pilot light valve 43, 'The pilot light valve is provided with anarm 44 on its stem, to which the operating chain 45 is By thus arranging the parts, the parts above thedeseams fiectorfplat are not only protected from the direct heat, which is deflected into and carried oif by the chimney,jbut a current of air is caused to flow across the burners, thus assisting in' the cooling. The air is also caused to circulate through the outer casing, which effectively ventilates it and assists in cooling the parts.

By the burner connections described, all of the burn- 9Y8 may'be used, or only the single burner, as desired. I have illustrated and described my-improved gas lamp indetail in the form preferred by' me on account of its structural simplicity and economy and conveniencein use.- I am, however, aware that it is capable of considerable variation in structural details without departing from my invention, and I desire tobeun- 'derstood as claiming the same specifically, as illustrated, as well asbroadiy.
