BURNER ATTACHMENT.

" Specification of Letters Patent.

Patented April 23, 1907.

Application filed June 9, 1906.!Serial No. 321,082.

To all whom it may concern.-

Be it known that I, GODFREY DAWE, a citizen of the United States, residing at Eau Claire, in the county of Eau Claire and State of Wisconsin, haveinvented a new and useful Burner Attachment, of which the following is a specification.

This invention has relation to burner attachments; and it consists in the novel construction and arrangement of its parts, as hereinafter'described.

The object of theinvention is to provide an attachment especially adapted to be attached directly to the chimney of a burner using an incandescent mantle.

The object is to confine the heat within the chimney in order to produce a more brilliant mantle with less consumption of gas, also to prevent the heat and products of combustion from escaping from the chimney and discoloring objects directly over it.

This is prevented even though the burner be in close proximity to such objects. The attachment also acts as a reflector to throw the light sidewise and downward. The attachment is provided with a material which is adapted to collect and retain the smoke and unconsumed particles thrown off by the flame.

In the accompanying drawings, Figure 1 1s a perspective view of the attachment. Fig. 2 is a vertical sectional view of the same.

The attachment consists of the hemispherical top piece 1, which is provided with a number of perforations 2. The annular plate 3 is secured at its edge to the edge of the hemispherical top piece 1. The screen 4 is located in the dome of the hemispherical top piece 1. Said screen is of com aratively fine mesh. The screen 5 is located on top of the annular plate 3 and is of comparatively coarse mesh. Thefibrous material 6 is located .in the hemispherical top piece and is interposed between the screens 4 and 5. Said fibrous material is preferably a mixture of asbestos and mineral wool, although any other suitable material may be employed.

The annular sleeve 7 is secured at its upper edge of the annular plate 3. Said sleeve 7 is provided with the vertically-extending openings 8, and its lower edge 9 is suitably cut in the form of lace patterns or filigree-work, the object being to reduce the metal in order that the attachment may not interfere with the radiation of light-rays from the burner and that the reduction of quantity of metal will correspondingly reduce the heat-absorbing material of the attachment. As at 10, portions of the metal cut out from the lower end of the sleeve 7 are turned inwardly, forming lugs which are adapted to rest upon the upper edge of the chimney 11. The upper end of the sleeve 7 is of greater diameter than its lower end, said increase in diameter being gradually accomplished throughout the longitudinal aXis of the said sleeve. The lower surface 12 of the annular ring 3 is brightened or otherwise rovided with material adapted to act as a re ector.

The attachment is adapted to be applied to the top of the chimney. The products of combustion ascend from the flame and pass through the fibrousmaterial 6. The upper fine screen 4 prevents the finer particles of the said material 6 from being blown through the perforations 2 and liberated in the atmosphere. At the same time the smoke and other unconsumed particles are retained by the fibrous material 6 and are thus prevented from escaping into the atmosphere. At the same time the draft from the flame passes through the attachment at the openings 8. The heat is retained within the chimney 11 and is prevented from ascending and discoloring or otherwise damaging objects located directly above the burner. The bright surface 12 acts-as a reflector and throws the light-rays sidewise and downward.

It will be observed that this device is attached directly to the chimney and is not suspended. Consequently it may be readily applied to all kinds of lamps, whether on chandeliers, wall-brackets, or hand-lamps. The metallic parts of the attachment are preferably made of aluminium; but they may be made of any other suitable metal. {pail While this attachment has been described as being especially adapted to be applied to incandescent burners, it may be used to ad- ICO vantage upon flame-burners, whether in cylindrical chimneys, globes, or open. It [is also obvious that minor changes and alterations may be made in the construction of the attachment without departing from the spirit of the invention.

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

1. A burner attachment consisting of a body portion having suitable erforations, a

fibrous material retained witlim said body annular sleeve supporting said body portion and plateand having suitable openings and adapted toreceive a chimney at its lower end.

In testimony that I claim the foregoing as I 5 my own I have hereto affixed my signature in the presence of two witnesses.

GODFREY DAWE.
