IIlIIERO'VEID APPARATUS FOR'CARBIJ'RETTING- AIR.

The Schedule referred to in these LettermPatent and making part` of the same.

To all whom it may concern Be it known that I, OLEAVELAND F. DUNDERDALE, of the city, county, and State of New York, have invented a new and useful Improvement for Carburetting Atmospheric Air in 'an automatic manner, for at-V tachment to fixtures, such as used for ordinary gas,

and in au apparatus for ipcreasing'the power of illumination of gas-lights and others, by an arrangement of a combined chimney and lens; and 'I do hereby declare the following to be a clear and exact description thereof, which will enablexothers skilled .in the ait to make and use thesame, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side view, partly in section, of my improyed automatic carburetter-apparatus attached to a Aside-wall gas-bracket.

Figure 2 is a sectional View `of my improved lens chimney. A

. Similar letters of reference indicate corresponding part-s.

My invention has for its object to furnish an improved means of causing a draught of ,hot air. to pass through tubes, heated by the llame, into a carburetting-chamber, in connection with the fixture, in an automatic manner, caused by being expanded by the heat of the dame of the burner, rising and passing along the conducting-tubes and into the chamber containing a hydrocarbon-liquid, which it volatilizes and passes to theV burner mixed with the same, where it is consumed, the passage to the burner from the carb'uretting-chamber being facilitated by the draught of the chimuey.. I

. Also, it has for its object the increase of the lightgiving power of gas-lights, lamp-lights, and others, by making. the chimney partly of a lens Von the dicptric or catadioptrc system, for magnifying andl parallelizing the rays that emanate from the said* flames, in an .economical manner about the apartment. It consists in the construction and combination of the' various parts of the apparatus, as hereinafter more fullyl described. p

A, in the drawing, represents an ordinary side-wall bracket-fixture, to which `is attached a tube, B, leading upward and back from the burner to the interior of the chamber containing the hydrocarbon liquid, one end of B extending downward through the centre of the flame (when an argand-burner is used) to a point clear of the point of lcombustion, Where pure' atmospheric air enters and rises, owing to the 4heating of the tube by the llame, to the chamber O, where it is further heated and forced along the pipe to the 'carburettingchainber in -a continuus stream, where it' mixes with the vapor of the liquid therein contained, and passes into and along pipe D to the burner, where it is consumed; the llame being first started by blowing with the breath through the flexible tube F, connected with the lower part of the carburetting-chamber, which also serves as a drain-pipe, for the contents of said chamber. I

' The chamber` C also serves to prevent the too rapidy draught of air through the chimney, and thereby preventing the carbon from being carried ont of a state of incandescence too rapidly, thereby increasing the quantity of light, by allowing it to remain longer in a state of white heat. This heater, may be made of any shape or form desired for appearances.

i The .draught or supply of the heated air passing through tube B into c iamber E, may be regulated by a cock, as at Cr.

The tube B, attached to chamber C, may be detached and lifted out of the chimney, by having a slide-joint, as at H.

'lhcchimney has a band of thick corrugated glass surrounding it, as shown at I, in Iig. 2, arranged as a leus, and made either separate or as partv of the chirn ney, constructed on the dioptlic, catadioptric, or other systems, the effect of which is to `increase the light by magnifying it and parallelizing the rays in a horizontal manner and direction -about the room where used.

I do not claima process for heating the products of combustion by means of the .dame of the burner, for I am' aware that such devices are old. Such a process is described in the patent of J clin H. Irwin, dated April 11,' 1865. v

Neither do I claim the chambers E and 0,-with the pipe-connection therewith, for they are represented in ymy patent of May 25, 1869; but

- AWhat I claim as new and useful, and desire to secure by Letters Patent,.is-

1. The tube/herein described and shown, attached to the lower side `of chamber C, so construct-ed and arranged, that its lower open end shall extend downward below the flame of the burner, substantially Vas and for the purpose specified.

2. In combina-tion with au air-carburetter, constructed as described, thecorrugated lens-chimney I, constructed and arranged substzxtntiallyV as described.
