B. A. POLLOCK ATTACHMENT FOR OIL BURNERS Filed March 25, 1940 Patented Dec. 8, 1942 UNITED STATES PATENT OFFICE ATTACHMENT FOR on. BURNERS Bernard A. Pollock, Petersburg. Va. Application March 23, 1940, Serial No. 325,629

1 Claim.

the flame is spread in a manner resulting in a smooth flowing flame free of flicker.

Another object of the invention is to provide a device of this kind which can be readily and conveniently applied to or removed from operative position with respect to the burner proper.

The invention consists in .the details of construction and in the combination and arrangement of the several parts of my improved attachment for an oil burner whereby certain important advantages are attained and the device rendered simpler, lessexpensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:

Figure 1 is a vertical sectional view illustrating an attachment constructed in accordance with an embodiment of my invention and in applied position;

Figure 2 is a view in top plan of the attachment as herein disclosed with the top or spreader plate removed;

Figure 3 is a fragmentary detailed sectional view taken substantially on the line 3-3 of Figure 1.

As disclosed in the accompanying drawing, C denotes a casing of any desired dimensions and configuration and which is open at its lower end and which has said lower end portion intersected by the cross members 2. Resting upon these cross members 2 at the central part of the casing C is a burner B of a well type. This burner B is preferably of cast iron and is provided in its side wall with the air inlet openings l and in its upper portion with the vertically spaced and inwardly disposed continuous flanges 3 defining the central openings 4. The top of the burner B, which is of a pot type, is also provided at its top with an outstanding surrounding flange 5 which has close contact with the sleeve member M surrounding the. applied burner B and resting upon and suitably secured, as at 6, to the members 2. The bottom of this sleeve member M is open while the upper end I is closed.

The casing C is provided with suitable supporting legs 8 for maintaining the casing raised above the surface upon which it is supported so that air may readily pass up through the lower open end of the casing C around the sleeve member M and also up between the member M and the burner B for flow into the burner B through the openings I. The lower portion of the burner B receives the oil which is delivered thereto through the pipe line 9 leading from a' suitable source of supply, and the member M at a point closely adjacent to the top I thereof has in communication therewith a flue F for carrymg off the products of combustion and, of course, creating the desired draft.

The foregoing features of the stove as described form no part of my present invention as the same are in accordance with the type of oil heater now already known.

As herein embodied, my improved attachment comprises an elongated hollow member I0 preferably circular in cross section, and which has its lower end ll closed with the opposite end open. The Wall of this member [0 is of material thickness and said wall adjacent to its upper or open end is provided therearound with a plurality of outstanding loop members l2. As illustrated in the accompanying drawing, these members l2 are three in number and equidistantly spaced circumferentially around the member I0. The member ID is adapted to be supported substantially axially of the burner B by the props Hi, there being one of such props M for each of the loop or eye members l2; The props i4 each comprises, in the present embodiment of my invention, an elongated bar provided at one end with an angularly related arm Hi. This arm I5 is short and straight and is insertible from below through one of the eye members I2 as particularly illustrated in Figures '1 and 2. arm 15 is snugly received within an eye member l2 with said straight arm H: in contact with the adjacent portion of the member I0 when the prop I4 is engaged with the desired supporting surface for the attachment which, in the present instance, is the flange 3 of the burner.

The degree of angle of the arms l5 with respect to the props l4 together, of course, with the length of such props determines the extent the upperend of the member I0 will be above the burner and, as is illustrated in Figure 1, it is to be The cate sections each semi-circular in form and the meeting edge portions of said portions at the longitudinal center thereof are provided with the extended lugs [8 which, as is illustrated in Figure 1, are snugly received within the upper end portion of the member ID whereby the plate [6 is maintained in desired position upon said member 10.

The side wall of the member M is provided with a suitably positioned opening [9 normally closed by a plate or the like. Aligned with this opening 1.9 is an opening 2| in the side wall of the casing C. This opening 2| is normally closed by a plate 22. The openings [9 and 2| are of such diameters to readily permit the mounting or placing of my improved attachment upon the burner B as well as the removal of the attachment. 1

The flow of the air into the burner B through the openings l and out through the openings .4

will draw ofi therewith vapor from the liquid fuel in the bottom of the burner B with the result that the combustion will be within the upper portion of the burner B with the flame passing outwardly through the upper opening 4 and spread by the plate l6 which will result in a smooth flowing flame free of flicker and such flame willbe circular in form as it passes upwardly beyond the assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim: n

An attachment for comprising an elongated hollow member closed at one end, outstanding loops at the opposite end portion of the elongated member and spaced circumferentially therearound, props provided with angularly related arms at the ends thereof for insertion from below through the loops, said" props providing means for supporting said member upon the burner with said elongated member extending downwardly and substantially axially of the burner, a substantially flat spreader plate provided at its axial center with a part fitting within the open endiportion of the elongated member whereby the spreader plate is supported by said elongated member above the burner, said spreader plate and elongated member being of a material to become red hot from the flame of the burner, a'marginal portion ofthe spreader plate being upwardly and outwardly disposed.
