LAMP-BURNER.

SPECIFICATION forming part of Iletters Patent No. 701,919, dated June 10, 1902. Application filed AugustZl, 1901. Serial No. 72,760- (No model.)

T0 at whom it may concerns h Beitknown that LSTEPHEN B. MORSS a'citizen of the United States, residing at Rahway, State of New Jersey, have invented cert-ain new and useful Improvements in Lamp-Burnsubstantially even flame, to distribute air in proper proportion 'to the flame and directly at the base of, the flame whereby to increase the steadiness of the'latter, and to also extinguish the flame when the'wick is'turned low and at the same time to prevent gases from rising from the wick-top.

A further object of the invention is to provide improved means for regulating or limiting the height to which the wick can be turned up, so as to prevent the wick from being turned up so high as to produce smoke.

In carrying out my invention I provide a perforated cone or thimble having an inweirdly-projecting flange or rim beneath the lower the cone or thimble, and means are provided for guiding the cone or thimble as it is moved by the wick. p

The invention also consists in the combi nation of wick-casing tubes and a cone-or thimblehaving a guiding portion with a stop interposed between one of the tubes and said guiding portion to regulate and-limit the ver-' tical movement of the cone or thimble when it is raised by the wick.

The invention also consists in the novel de' tails of improvement that will be more fully claims.

Reference is to be hadto the accompanying modification.

In theaccompanying drawings, inwhich similar numerals of reference indicate corresponding parts in the several views, l.indicates a perforated thimble, cone, or air-distributer, which may generally be of ordinary or suitable construction in so far as the air-distributing portions are concerned,

and beneath its perforationsthe cone or thim ble is provided with an inwardly-extending flange or rim i that is adapted to rest upon a wick 2, that is contained in the usual manner between the wick-casing tubes 3 4, any su itable means( not shown) being provided for raising and lowering the wick. By this means the cone or thimble is enabled-to be made of such width as to extend over the wick, and thereby when the latter is raised from the tubes and the oil lighted the flame will burn from the side of the wick above the outer tube 3, the air from the perforations in the cone or thimble will be directed close. to the base of the flame, and the heated cone or thimble, and particularly the flange resti'ngupon the wick, will act in the nature of a gasifier of the oil when the wick is raised and in use,thereby increasing the brilliancy of the flame. Furthermore, the flange 1 protects the top of the wick from being burned, and a more-even flame results than where the flame is burned at the'top of the wick in well-known manner.

cone' or thimble than is possible with the cones or thimbles of well-known construction heretofore in use that did not extend over the wick. 9o

The cone or thimbleiil is also provided with r a depending guiding portionl that is shown passing into the tube 4, whereby as the thimble is raised and lowered by the wick it will be guided ina vertical direction and main-. tained in proper position upon the wick and also'kept from tilting, so as to prevent flame from burning at the top of the wick. To prevent the 'flame ,from being .raised'too high, I provide one or morejstops interposed between the wick-casing tube and the thimble, and for this purpose I have shown the tube a, provided with pins or projections 5, that extendinwardly and pass through slots 1 in the guide 1 of cone 1. The slots I have shown y It will also be seen that as the cone or thimble has .of the slot, and thereby as the wick is raised the bottom edge of the slot will encounter the wick to prevent the latter from being raised toohigh. Thelipl ofslot1preventstheoone or thimble from becoming loosened or dropping ofi the lamp when the latter is handled.

- This stop for the cone or thimble is simple and effective and one that can readily be understood by those accustomed to using lamps. Any desired number of such slots and pins can be used, and I have shown four of them which will tend to maintain the thimble in a substantially horizontal position when raised by the wick or, in other words, will tend to prevent the cone from becoming tilted.

The wick can be turned to any intermediate height Within the vertical limits of portion 1 of slot 1, and the relative arrangement of the slot or pin is such that when the wick is turned down sufficiently far the cone or thimble will rest upon tubes 3 3, will thus act to extinguish the flame, and will prevent gases from escaping.

If desired, the flange 1 can be imperforate or perforated or slotted or fluted or grooved horizontally. This latter arrangement is shown in Fig. 4, wherein the flange or rim 1 is grooved, fluted, or corrugated radially, as at l When such flange or rim rests upon the wick, radial spaces are formed between the flange and the wick in which gas or vapor may collect, and the latter will be distributed to the flame, with the effect of increasing combustion and brilliancy of the flame. When the flange or rim 1 is perforated, gases that rise from the surface of the wick will enter the perforated cone or thimble and will be distributed mixed with air to the flame with the advantage of increasing the brilliancy of the latter.

I do not limit my invention to the precise details shown and described, as they may be varied without departing from the spirit thereof.

Having now described my invention, What I claim is 1. In a central-draft burner a wick and an air-distributer having an inwardly-extending flange or rim resting upon and supported by the wick whereby the distributer will be raised and lowered by the wick, substantially as described.

2. In a central-draft burner, the combination of wick-casing tubes and a wick therebetween with a perforated air-distri buter having an inwardly-extending flange or rim resting upon the wick when the latter is raised above the tubes and acting as an extinguisher by closing the space between the tubes when the wick is turned down, the distributer being provided with a depending guide guided to travel along the tube to direct the vertical movement of the distributer when raised or lowered by the wick, substantially as described.

3. As an article of manufacture, a perforated air-distributer for a lamp or stove having a flange or rim to overlie a wick, said flange or rim having grooves providing spaces between the wick and the flange or rim to receive gas or vapor, substantially as described.
