NO-CHIMNEY BURNER.

SPECIFICATION forming part of Letters Patent No. 559947', dated May 12, 1896.

Application filed May 31, 1895. Serial No. 551,0 l4. (Ne model.)

To all whom, it' may concern:

Be it known that I, FRANK RHIND, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and nseful Improvenents in No-Chimney Burners; and I do hereby declare the following to be a full, clear, and exact description of the invcntion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to no-chimney burners, and has for its object to provide a construction of wick-tube which will prevent the flame from running to a point at the center, and a Construction of deflector to act in connection therewith, and which will also serve as a guide in trirnming. It is of course well understood that in burners having a chimney the shape of the fiame is to a great extent determined by the shape of the defiector, or, as it is frequently called, the dome. In a no-chimney burner, however, entirely different conditions exist. Combustion is partially supported by outside air, the tendency of which, moving as it does from all directions is to point the flame-that is, make it run to a point at the center-and of course causing the fiame to smoke. The de fiector in a no-chimney burner counteracts this efiect to a limited extent. It also acts to a limited extent to prevent the fiame from spreading when exposed to draft-s. The deflector, however, in a no-chimney burner by no means accomplishes the result that is accomplished in the other class of burners by a defiector in connection with a chimney. The only way in which it has been possible heretofore to modify the shape of the fiame in no-chimney burners has been by giving to the top of the wick a concaveform-that is, trimming it so that it is lowest at the center, leaving the ends highest. My present improvement enables me to provide a no-chimney burner which will wholly prevent the fiame from running to a point at the center by exposing more of the wick at the ends than at the center, which will require no trimming of the wick but a straight cut, and which will provide a guide for making the cut. 5o

lVith these ends in view I have devised the novel construction of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to desgnate the several parts.

Figure l is a side elevation, partly in section, illustrating the application of my invention to a bieycle-lantern having an inclined wick-tube; Fig. 2, a side elevation corresponding therewith; and Fig. 3 is a view corresponding with Fig. 1, illustrating the application of my novel invention to an ordinary no-chimney burner.

l denotes the wick-tube, and 2 an air-defiector. The novel feature of the wickiube is that it is made highest at the sides, as at 3, and lowest at the ends, as at eL, thus protecting the wick at the sides and leaving it exposed at the ends, so that when the wick is trinmed straight across the fiame will tend to run up at the ends and will frequently be depressed slightly at the center, the tendency to run up at the center being wholly overcome.

In practice the sides of the wick-tube are preferably ourved from end to end, as shown in Figs. 1 and In connection with this form of wick-tube I make the top of the defiector straight across, as at 5. By that I mean that the line of the top of the deflector is parallel to the plane of the burner, so as to So form a perfect guide in trimming the wick, it being simply necessary to cut the wick straight across the top of the defiector. I also preferably make the ends of the deflector lower than the sides, as at 6, so as to pernit air to pass inward freely to support combustion at the ends of the wick.

Having thus described my invention, I claim 1. In a no-chimney burner the combination go with a wick-tube whose sides at the top are cnrved so as to expose more wick at the ends than at the center, of an air-defiector acting as and for the purpose set forth whose sides at the top are straight so as to form a guide in trimning whereby a fiame higher at the ends than at the center is produced from a wick cut straight across. I

2. In a no-chimney burner the conbination with a, wck-tube whose sdes at the top are 5 curved so as to expose more wck at the ends than :tt the center, of an ur-deflector acting as and for the purpose set forth whose sides at the top :tre straight so as to form a guide in trinnning' and whose ends are lower than the sdes for the purpose set forth, whereby IO a fiame higher at the ends tha-n at the center is produced fron a wick cut straight across. In testnony Whereof I affix my signature in presence of two witnesses.
