IVIANTLE-SUPPORT FOR GAS-BU RN ERS.

SPECIFICATION forming part of Letters latent No. 699,857, dated May 13, 1902.

Application filed May 31, 1901. Serial No. 62,464. (No model.)

To aZZ whom it may concern:

Be it known that I, HELEN HORTON TIBBS, a citizen of the United States, residing at West Seneca, in the county of Erie and State of New 5 York, have invented a new and useful Improvement in Mantle-Supports for Gas-Burners, of which the following is a specification.

This invention relates to the support employed in Welsbach and similar incandescent 1o gas-burners for sustaining the refractory mantle.

My invention has for its object the provision of a cheap support of this character which causes the mantle to center itself there- I 5 on, which offers a small contact area to the same, and which permits the air and products of combustion to ascend between the mantle and the support and escape freely at the top of the mantle.

In the accompanying drawings, Figurezl is a sectional elevation of my improved mantlesupport and the cap or burner-tip upon which it is mounted. Fig. 2 is a top plan view thereof. Fig. 8 is a detached perspective 2 5 view of the support,

Like letters of reference refer to like parts in the several figures.

A is the customary cap or burner tip of a Welsbach or similar burner, and B the forami- 3o nous disk applied to its upper end.

My improved mantle=support is preferably molded of pipe-clay; but it may be made of any other suitable material. C is a vertical rod forming the standard of the support. In

3 5 the construction shown in the drawings this rod is provided at its lower end with a separate rod or stem (:1, which is seated in a vertical socket e, secured centrally in the foraminous disk B, as shown in Fig. 1.

The standard is provided at its upper end with a head or enlargement F, from which the refractory mantle is suspended, as indicated by dotted lines in Fig. 1, and which is composed of a plurality of comparatively thin 4 5 longitudinal wings f, projecting radially from the upper end of the standard and arranged equidistant around the axis thereof. The head or enlargement formed by these wings is tapered upwardly to conform approximately to the contracted upper end of the mantle, while the edges of the wings preferably recede or are beveled downwardly from the wide central portions of the wings toward their lower ends, as shown in the drawings, thus forming a winged head which tapers from its middle toward both ends.

By reason of the upwardly-tapering form of the head F the mantle readily centers itself thereon. The thin wings of the support present a narrow contact-surface to the mantle, and the wide spaces between the wings extend throughout the length of the latter and afford ample passages for the ascent of the air and products of combustion between the wings and the escape thereof at the top of the mantle, permitting a free, direct, and uninterrupted draft or ventilation and effectually preventing smoking and the deposit of soot on the mantle resulting therefrom. By gradually narrowing the wings f from their salient middle portion toward their lower ends the ascending current of air and products of combustion on coming in contact with the beveled edges of the wings are gradually and gently deflected laterally into the passages between the wings, thus avoiding a sudden turn or disturbance of the currents on coming in contact with the edges of the wings and insuring a steady light.

' I claim as my invention-+ 1., A mantle-support for a gas-burner, comprising an upright rod or standard, and ahead surmounting the same and composed of a plurality of independent wings extending outward from the rod, arranged lengthwise there- 8 5' of and separated from each other throughout their length, thereby permitting a direct and uninterrupted ascent of the products of combustion on opposite sides of the wings, substantially as set forth.

2. A mantle-support fora gas-burner, comprising an upright rod or standard, and a head surmounting the same and composed of a plu rality of independent longitudinal wings separated from each other throughout their 95 length and having their lower portions gradually narrowed toward the lower ends of the wings,whereby the lower portions of the win gs present upwardly-diverging edges which gently deflect the ascending gases laterally on opposite sides of the wings, substantially as set forth.

3. A mantle-support foragas-burner, comprising an upright rod or standard, and a winged head tapered from its middle portion toward both ends and having its Wings arranged lengthwise of the rod, substantially as set forth. I 1o Witness my hand this 28th day of May, 1901.
