FLAME sPREADER.

Specification of Letters Patent.

Patented Dec. 22, 191d.

Application filed October 4, 1912, Serial No. 723,958. Renewed October 22, 1914. Serial No. 868,123.

To all whom it may concern:

Be it known that I, Lens Pnonu (Imus TENSEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Flame-Spreaders, of which the following is a specification.

This invention relates to the class of lamp burners which are designed for burning coal-oil and similar hydrocarbons, and which require a lar e amount of oxygen to supply combustion and produce a good illuminating flame.

An object of my invention is to provide a novel and improved flame spreading and air deflecting device wherein the conflicting air currents are deflected to one side before reaching the flame and wherein means is provided to permit an increased amount of air to be directed to the flame at the sides thereof, thereby increasing the size and brilliancy of the flame.

It is also an object of my invention to provide a device of the character stated which can be readily applied to any ordinary lamp, lantern or stove burner using a flat wick, without altering or modifying the structure of the burner, and without cutting or otherwise defacing the same.

It is well known that various attachments have been devised for the purpose herein set forth, but as far as known to me such devices are very complicated in construct1on, thus incurring a great expense in the manufacture thereof, or are incapable of performing the functions desired, while my device is not only simple and durable but can be manufactured and placed upon the market at a minimum cost, and has proven upon test to effectively perform all of the require ments herein claimed.

With the above and other objects in view, my invention relates to such details of construction and to the arrangement and combination of the several parts as will be hereinafter fully described and specifically pointed out in the appended claims.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a sectional view of an ordinary lamp burner illustrating the application of my invention. Fig. 2 is a section on the line 2-2 of Fig. 1, and Fig. 3 is a detailed perspective view of the flame spreader and draft deflector.

Referring to the drawings, wherein is illustrated the preferred form of my invention, the numeral 1 designates a lamp burner dome of the ordinary type, having the usual slot 2, and supporting structure 3. The draft usually created by reason of the slot 2 will very often produce an improper combustion, thereby causing the. flame to smoke, thus soiling the chimney and producing a weak and irregular light. Even though proper combustion would take place it is always desirable that the flame should be evenly spread to afford a maximum illuminating power. Therefore, I have provided a combined flame spreader and draft deflector, composed, preferably of a single piece of sheet metal, stamped or otherwise struck out, after which operation the device is bent in a novel and peculiar manner which enables the same to be properly supported within the dome of the burner, and cooperate with the latter whereby the flame is uniformly spread and the draft deflected to such a degree as to render an efficient illuminating flame. Such a device, as previously described, when bent into proper position, preferably comprises two sheet metal supporting members 4, connected to-' gether through the medium of 2 parallel strips 5, both of which are slightly grooved at 6 to materially strengthen them. At the top of each supporting member and bent upwardly at right angles thereto I provide a tongue 7 terminating in a lip 8, the purpose of which will be subsequently described.

After the device has been bent to the proper shape, the same is fitted within the burner in the following manner :The dome 1 is first opened and raised upon its hinge 9 to expose the inside thereof and to permit access thereto. The device is then suspended within the dome by means of the lips 8, each lip overlapping the lower edge of the slot 2 as is clearly shown upon reference to Fig. 1 of the drawings. When the device is thus suspended within the dome, the latter should then be closed so as to again assume its normal position, in which event the device is in proper operative position.

The peculiar construction of the device, it will be seen is such as to produce a draft deflector by reason of the supporting members 4, and a flame spreader by reason of the tongue 7, thus an extremely simple device accomplishes at one and the same time two distinct and independent functions.

It will be seen from the foregoing, taken in connection with the accompanying drawings, that the wick holder extends through the opening formed by the two strips so as to bring the flame within the device, where it is properly spread by reason of its contact with the tongues.

It is thought from the foregoing "that the advantages and novel features of my invention will be readily comprehended.

It will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in details of construction, proportion and arrangement of parts may be made within the scope of the appended claims and without sacrificing any of the advantages of my invention.

. Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a burner having the usual flame slot in its dome, and a wick tube disposed directly beneath the said slot, of a flame spreader adapted to be arranged within the said dome, the said flame spreader comprising a pair of spaced arms, disposed one upon each side of the said tube out of engagement therewith and below the top thereof to form an air space between the said arms and the said tube, support means dis posed for engagement with the ends of the said tube to prevent lateral movement of the device, and means carried by said support member adapted for engagement with the terminals of the said slot, as and for the purpose set forth.

2. In combination with a burner having the usual flame slot in its dome, and a wick tube disposed directly beneath the said slot,

of a flame spreader composed of a single piece of sheet metal adapted to be arranged within the said dome, the said flame spreader comprising a pair of parallel arms, one of which is disposed upon each side of the said tube below the top thereof, support means extending at right angles to the said arms, the said means being disposed for engagement with the ends of the said tube to prevent lateral movement of the device, outwardly directed tongues formed upon each end of the spreader and upon the same plane as the terminals of the flame slot, lips formed upon each of the said tongues adapted for engagement with the slot terminals to support the device, and crimped portions extending throughout the length of the arms for reinforcing them, as and for the purpose set forth.
