5 Claims.

This invention relates to highway flare torches for use as warning and safety lights in construc-' tion work and by motor busses and trucks when stalled on the highway and the invention has for one of its objects to provide such torch with a burner of extremely simple and sturdy construction.

Another object of this invention is to so construct the burner that it efficiently protects its flame in any kind of weather.

A further object of this invention is to so construct the burner that sudden shifts and increase in intensity of the wind will not affect the combustion of the fuel in producing the flame of the burner.

Another object of this invention is to provide the burner with means whereby a number of torches can be conveniently collected and carried in one hand. I I r A further object of this invention is to so conlighted and quickly and efficiently cleaned.

A further object of this invention is to provide the burner with flame openings which are arranged so as to provide at all times 'a protected exit for the flame thru one or more of these flame openings.

All these and other objects'and attendant advantages will become more readily apparent from the detailed description of the invention which follows, reference being had to the accompanying drawing in which Figure 1 is a top plan view of the burner.

Figure 2 is a longitudinal sectional view of the burner as it appears mounted on and locked to the torch body, the section being taken on the line 2a:2a: of Figure 1.

Figure 3 is a vertical sectional view thru one of the flues of the burner, the section being taken on the line 3:z:3a: of Figure 2.

Figure 4 is a vertical sectional view of the wick holder and combustion chamber of the burner, the section being taken on the line 4:r-4:r of Figure 2.

In the figures of the drawing like reference numerals indicate like parts.

The burner for highway flare torches forming the subject matter of our present invention is adapted to be removably mounted to the neck I of the torch body or font 2. The neck is provided with a series of fixed locking cams 3, 3 which hold the burner clamped and locked to the neck I as will hereinafter be described.

The burner proper comprises a single piece casting to provide an extremely sturdy constructo have the locking lugs 6, 6 engage under the locking cams 3, 3 and have the cams draw the base down onto the neck and hold it clamped thereto with a suitable washer I located between it and the base to provide a tight joint between them.

In the center the base 4 is provided with the wick holder 8 which comprises a short vertical duct in which is held the wick 9 to keep its lower end suspended in the torch body thru the neck I thereof and keep its upper end projecting substantially half way into the dome [9 above the wick holder. One or more spirally arranged ridges I l within the wick holder serve to hold the Wick in its proper position and provide for its adjustment up or down in the holder by simply rotating it in either one or the other direction.

The dome 10 extends horizontally over the wick holder and provides the combustion chamber for the burner. vided' in the sides of the dome near the bottom thereof and are located on opposite sides of the wick Ill in close proximity to the top end thereof in order to supply air thereto for the combustion of the fuel. The air inlet openings extend angularly thru the Wall of the dome substantially radial to the wick and thus direct the air thereto. As illustrated in Figure 4 the air inlet openings are also inclined downwardly away from the bottom of the dome so as to drain any rain water which may collect in the combustion chamber around the wick.

A pair of vertically arranged open ended flues l3, l3 are provided on the dome l0 and form a combustion chamber therewith. These flues are located on each side of the dome l0 and provide the flame openings in the top and bottom of the combustion chamber which prevent the wind from blowing directly thru the combustion chamber no matter from what direction it strikes the burner. The flames from the burner thus normally issue from the open top of each of the flues l3 and provide a vertical twin flame for the burner. Air is admitted thru the open bottom of the flues while the flames issue from the top thereof and furnish additional air for an effi- Air inlet openings I2, 12 are procient combustion of the fuel in the combustion 7 chamber.

When a high wind blows against one of the fiues of the burner, it causes the flame to be forced out of the top' and bottom of the other flue and vice versa. When a wind blows into the top ofthe flues, .the flames are forced out thru the 7 bottom thereof. In-iact, no matter in what direction" the wind blows against the burner, the

combustion chamber is always protected against a direct draft therethru to prevent the blowing out of the flame, of the burner'while sufiicient '25" V ofjthe, flus it leaves the; burner. Under certain protected flame openings are provided to prevent a smothering'of the flame.
