GAS-LAMP.

- specification of Letters Patent.

Patented Feb. 28, 19i1.

-App1ication filed January f6, 1909. Serial No. 472,700.

To all whom. it may concern:

Be it known that I, Amrnsn H. HUM- remain, a citizen oft-he UnitedStates, residmg at New York city, New York, have in vented certain new and useful Improve.

ments in. Gas-Lamps, of which the following is a specification.

This invention relates to improvements in gas lamps. My present invention relates to improvements in gas lamps having in verted burners, such as'is illustrated in U. S. Latter-s Patent No. 841,323, issued to me Jan. 15,1907. 7 a

The main object of this innention is to gas lamp, an improved mantle support by which the mantles are effectively and safely supported, and one which is capable of very easy and rapid adjustment without danger of injury to the mantles carried thereby.

Further objects, and objects relating to structural details, 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.

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

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

Figure l is a detail vertical section of a structure embodying the features of my invention, parts being shown in full lines. Fig. 2 is a horizontal section taken on a line corresponding to the broken line 22 of Fig. 1. Fig. 3 is a detail vertical section of a modified construction. Fig. 4 is an enlarged detail perspective of the mantle support guide members of the modified structure shown in Fig. 3. Fig. 5 is' an enlarged detail takenon a line corresponding toline 5--5 of Fig. 4. Fig. dis a detail vertical section showing a-modified construction having a single supporting and guiding rod. In the drawings, similar reference characters refer. to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the gas supply pipe, which is provided with a coupling. member 2, from which depends a the upper section 5,

.wardly-projecting flange 9.

-- the globe in its open position,

I catch 20 on the hinge member gas delivery arm 3.. This is suitably connected to the gas delivery ring 4, the details of the connection not being here illustrated, as they form no tion. Through this ring t is arranged a draft chimney which is preferably made up of sections 5- and 6, the lower section 6 being arranged to project into the lower end of and being spaced from admission of air lower chimney section 6. This flange is provided. with a downwardly-projecting por- On the lower end chimney section 5 is an out-' A flange-like band 10 is mounted on the member 7, the outer edge of the member 8 being preferably secured to this band 10.-

The mixing tubes 11 of the burners 12 are arranged through the flanges '7 and 9 in posi-. tion to receive the gas from the delivery nozzles 13 on the delivery ring 4'. These burner tubes are preferably threaded through the lower flange 7, the upper flange 9 serving as a guide for their upper ends. Thus arranged, the burner tips are brought below the deflecting member 7, which serves to guide the product of combustion to the chimney, and a draft opening for thechinr ney is provided above the flange 7, this arrangement being a modification of ture illustrated and described in my Letters Patent No. 863,182, dated August3, 1907.

The flange 9 is provided with air inlet openings 9 for the passage of air to the chimney above the flange 7, which also causes the air to circulate about the burner tubes in passing to the chimney from above the flange 7, thereby assisting in cooling the same.

The flange 10 is tion 8 at its outer edge. of the upper provided with air inlet the strucpart of the present invenfrom above the-fiange-like depending member? at the lower end of the openings 14;, through which the air passes I into the globe 15, and thence to the burn ers. The globe 15 is carried by a globe-sup.- porting ring'or band 16, which is mounted by means of a pi"ot, as 17, upon the hinge member 18 carried by the band 10. To hold I preferably provide a. hook 19 which engages over the 18, as is indicated by dotted lines in Fig. 1. .1

The globe is retained in the closed position by means of the pin 21 which is adapted to engage the slotted arm arranged oppositelyoii the hinge.

The outer casing 23 is preferably made .vertically adjustable to aliord access to the parts above the chinmeyflanges- The deflector 2.4; of the outer casing is shdably mounted on the supply pipe 1, and'is con nected to the outer casing bymeans of the straps 25. This connection for the casing to the deflector guides the casing in its vertioal adjustment and holds the same in a spaced relation to the upper part of the.

chimney, the lower end of the casing being arranged to reston the upper edge'of flange 10. The outer casing is provided with air inlets 26, through which air passes to the.

burner tubes, and this also permits a circulation up through the outer casing, thereby assisting in cooling the parts.

The mantles 26 are suspended below the burner tips, being preferablycarried by a support 27 common to all of them. This a support is adapted to receive the ring-like mantle holders 28, the mantles being secured at their upper ends to the holders. The mantle support is retained in its operative position as by means of a suitable button, as

27. The mantle support is supported in its inoperative position by means of the vertically adjustable supporting rods 29, which are arranged through the chimney flanges,

and preferably between the chimney and the gas delivery ring' t, guiding sleeves 30 be- "-'ing -providect therefor. These sleeves are carried by the chimney flanges, as isclearly illustrated in Fig. 1. These supporting rods 29'guide the mantle support in its vertical adjustment so that the mantles are brought into proper relation to the burner tips, and

are not likely'to be injured in their adjust-.

ment. By this arrangement, the mantles can be qu ckly replaced as occasion may require, and burned off and adjusted into operative position without vdanger of injury thereto.

' In the' m 1dified construct-ion shown in Fig. 3, a single supporting rod, as 31, is

provided, so that the mantlesupport can be swung to' one side, as is indicated by dotted lines 1n Fig. 3. In thisconstruction, 1 provide the mantle plate with an .upwardly projecting guide arm 32, which is adapted :to engage the guides 33 provided therefor on.

the chimney flange, see Figs. 4 and 5. This,

in' connection with the rod '31, efiectively guides the mantle support into position so that it may be quickly adjusted without liability, of injuring the mantles carried thereby. I a

In'the modified construction shown in Fig. 6, thesinglesupporting rod 31 is of such shape in cross section as to prevent the arotative movement of the'mantle support so thatit is guided into itsvertical adjustment "into place Y I have illustrated and described my invention in the form which I find very satisfactory in use, and in the construction illus-- I claim as new and desire to secure by Letters Patent is\ I 1.
