time interval is necessary between the light-k s ing of the burner and its successful func-- tioning. Furthermore, when the conventional burner operates, 1t produces carbon which, when entrained in air, forms smoke.l

This is particularly true in the burning of i heavy oils of low volatility. Among the specific objects of my invention are those which'obviatethese defects. More specifically, my device comprises means for initially burning the more volatile portionsof the 1.', oil and utilizing the heat of combustion thus obtained for -subsequently igniting and burning the heavier portions of the oil. In my device an improvement is made of few and simple parts, which lend themselves :a readily to multiple production and may be easily and cheaply manufactured and installed or repaired. t

With these and other objects in view, my invention has relation to certain novel features of construction and arrangement of4 parts as will be hereinafter more fullyA described and pointed out in the claims and illustrated in the drawings. Fig. 1 is a plan view of the conventional 30 oil burner with my improvement shown.

Fig. 2 is a front elevation of the structure shown in Fig. 1.

Fig. 3 is an elevation of my specific improvement to an oil burner.

Numeral 4 indicates a cast cylindrical cup having the tapped hole in its'center and the peripheral flange (6). The supply pipe (7 is in threaded engagement in the tapped l hole Numeral 8 designates a perforat- -10 ed sleeve having perforations (9). Numeral 10 designates a cylindrical cap having the top (11) and depending flange (l2). Tn the cylindrical cup 10 is formed a central opening cofaxial with the pipe 7. Numerals 13 designate rods passing through perforations in the top (1l) and through holes in the ears (14) which are formed integral with the cast cylinder cup There are a plurality of such rods (13). By means of nuts (15) the perforated sleeve (8) and the cylindrical cap (10) and the cast cylindrical cup (4) are secured in frictional engagement. On the supply pipe (7) in space relationship witlrthe bottom of the cast cylindrical cup (4) is secured the'imperforate disc (16). 55 There is no iiuid communication between the supply pipe (7 and the imperforate discl (16).w The open end of the supply pipe (7 f terminates in the bottom of the perforated disc (17 In operation by static, pressure 60. or otherwise, the oil is forced upward through the supply pipe 7) on to the perforated disc (17). The lighter portions of the oilare consumed on this disc while the heavier portions pass through the perforations of the disc and fall on to the imperiorate disc (16) .and bowlof cup (4) where they are consumed. The heat and flame from both discs is confined in the perforated sleeve (8) and the cast cylinder cup (4) 70 and the cylindrical ca (10). The flame and heat also pass upwardly and outwardly` from the cylindrical cap (10)..

The operation may be further described as follows?V When the oil reaches the perforated disc (17) it is ignited by some external means such as a torch or by any mechanicali ition device. The first oil to burn is the ighter oil. Before the Hash point of the heavier 80 oil has been reached, it. will have passed through the perforations inthe disc (17 ).-on tothe imperforate disc (16). The heat of combustionof the lighter portions .of the oil is such as to ignite and perfectly burn the 35 heavier portions of the oil that have fallen on the imperforate disc (16). By these means the initial lighting is' facilitated because the lighter oilhas the lower iiash point or kindling temperature, .and the production of carbon and smoke is either eliminated or minimized because the proper oxygen supply is present for combustion for both the light and heavy oil and this supply is had 95 in the presence of suiiicient heat to crack and break down the oil to a gas or vapor before being burned. The idea of the entire device is to burn gas that has been generated from oil instead of oil directly.

What I claim is: l. An oil burner comprising in combination, a cylindrical cup having a tapped hole in its center, and having a peripheral flange, a fuel supply pipe secured in the tapped hole of saidy cylindrical cup, a perforated sleeve positioned within the peripheral flange of said cylindrical cup, a cylindrical cap positioned on said perforated sleeve, rods passing through perforations in'said cylindrical cap, and through holes formed in ears, which in turn are formed on said cylindrical cup, for securing said cup, perforated sleeve and cylindrical cap together, an imperforated disc secured to said fuel' supply pipe,'be

tween said cylindrical cup and said cylindrical cap and in spaced relationship therewith.

2. An oil burner comprising in combination, a cylindrical cup having a tapped hole in its center, and having a peripheral flange, a fuel supply pipe secured in the tapped hole of said cylindrical cup, a perforated sleeve positioned within the peripheral iange of p cap, and Nthrough holes foriiied in said cylindrical cup, a cylindrical cap positioned on said perforated sleeve, rods passing through perforations in said cylindrical ears, which in turn are formed on said cylindrical cup, for securing said cup, perforated sleeve and cylindrical'ca-p together, 3a perforated disc secured to said fuel supply pipe, between said cylindrical cup and said cylindrical cap u yand in spaced-relationship therewith.

3. An oil burner comprising in combination,-a cylindrical cup having a tapped hole in its center, and having a peripheral fiange, a fuel supply pipe secured in the tapped hole of said cylindrical cup, a perforated sleeve positioned within the peripheral liange of said cylindrical cup, a cylindrical cap posiy tioned on said perforated sleeve, rods passing through vperforations in said cylindrical L cap, and through holes formed in ears, which in turn are formed on said cylindrical cup, or securing said cup, perforated sleeve and cylindrical cap together, a perforated and an imperforated disc. secured in spaced relationship to said fuel suppl pipe, between said cylindrical cup and saidy cylindrical cap and in spaced relationship therewith.

4. An o il burner comprising in combination, a cylindrical cup having a tapped hole 1n its center, and having a peripheral flange,

a fuell supplypipe secured in the tapped hole of said cylindrical cup, a perforated sleeve positioned within the peripheral flange of. said cylindrical cu a cylindrical cap positioned on said perforated sleeve, rods passingrthrough perforations in said cylindrical cap, and through holes formed in ears, whichl in turn are vformed on said cylindrical cup, for securing said cup, perforated sleeve and cylindrical cap together, an imperforated disc secured tosaid fuel supply pipe, but not in fluid communication4 therewith, a perfoimperforated disc, said perforated disc secured to said fuel supply pipe above said imperforated disc, said perforated and imp erforated disc positioned between said cylmdrical cup and said cylindrical cap.

5. An oil burner comprising in combination, a cylindrical cup having a tapped hole in its center, and having a peripheral iange, a fuel supply pipe secured in the tapped hole of said cylindrical cup, a perforated sleeve positioned within the peripheral flange o f said cylindrical cu a cylindrical cap positioned on said perforated sleeve, rods passing through perforations in said cylindrical cap, and through holes formed in ears, which in turn are formed on said cylindrical cup, for securing said cup, perforated sleeve and cylindrical captogether, a perforated disc secured tosaid fuel supply pipe permitting oil under pressure fromH the fuel supply pipe to overflow into said perforated disc, and being strained there through said imperforated disc positioned'between said cylindrical cup and said cylindrical cap.

In testimony whereof I affix my signature.
