IMPROVEMENT IN GAS-BURNERS.

Irire Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

specification, whereint igure 1 is a vertical section of the said gas-burner, an j Figure 2 isa plan ofthe same.

Similar letters denote the same parts.-

Revolving gas-burners have heretofore been made of a'series of metal tubes passing out from a central vertical tube that revolved upon a pivot, the jets of gas 'standing' as tangents to the tubular arms, and causing the revolution of the burner.

Gas-burners of this kind are costly, because the separate parts have to be united together by joints that are expensive to construct, andy the biu'ner becomes so heavy as to produce considerable friction upon the pivot, and prevent the burner revolving freely; besides this, the pivot is very liable to wear a hole in the burner, or itself become blunt, thus increasing the friction.

Bearings of stone, and of glass set in metal, have also been used for the pivot.

My invention consists in formingthe revolving portion of the burner, including the jet-arms, the vertical cylinder, and 'the bearing for the pivot, of one piece in glass, whereby a very light revolving burner is Obtained. The pivot-bearing Vis very s1nooth,hard, and frictionless, there are no joints to become leaky, and the holes in the jet-arms do not become corroded'and stopped by the action of the gas and flame', as is the case with metal burners. l

I also attach the baseof the revolving burner to the gas-pipe by a rubber tube, so as to prevent injury to the glass, and to facilitate the application of the revolving burner to any ordinary gas-burner.

In the drawingsais the vertical tube of the revolving gas-burner; b y

b, the jet-arms; and c, the pivot-bearing; all formed in one piece of glass.

cl is the vertical supply-tube, with the pivot e at its end, and the side opening i, for the gas to pass out of.

f is the cup to contain mercury, glycerine, petroleuin, water, or other liquid, in which the lower -end of the tube a revolves, said material forming a packing to said tube a.

vThe cup f and tube d are united at the point l by cement, such as shellac, to render the parts. perfectly ti ht;

'gThe construction ofthese parts'is facilitated'in consequence of their being made separately, especially whenof glass.

From the lower end of the tube d, an India-rubber tube m extends, so as to be slipped upon the gasburner p, or other tube from which the gas is supplied.

This forms an easy and reliable means of connection, and avoids all risk of injury to the glass in attaching the burner.

What'I claim, and desire to secure by Letters Patent,- is- 1. 'The revolving gas-burner, with the tube a, arms '-b b, and pivot-'bearing o, all made in one piece of glass,

as and for the purposes specified.

2. The tube d, with the pivot e at its end and' the opening i, in combination with the cup f and .revolving burner, when the cup f and tube d are of glass, andA
