LAMP-BURNER ATTACHMENT.

Specification of Letters Patent.

Application filed January 20, 1912.

Patented Jan. 28, 1913. Serial No. 672,448.

To all whom it may concern Be it known that I, Gnonon WV. SMITIISON, a citizen of the United States, residing at Madelia, in the county of Vatonwan and State of Minnesota, have invented a new and useful Lamp-Burner Attachment, of which the following is a specification.

This invention relates to attachments for lamp burners, and has for its object the provision of a readily attachable and detachable device, adapted to fit upon any ordinary lamp burner and operating when attached thereto to greatly improve the combustion and as a consequence effect a saving in fuel together with a better illumination. These objects are accomplished by the peculiar conformation and relation of the parts of the attachment, whereby the oil in the wick is more perfectly gasified before being supplied to the flame, and the supply of air is properly distributed and supplied to the flame in such manner as to secure practically perfect combustion, thus avoiding the smoke and odor usually associated with oil burning lamps.

The invention as thus outlined and as hereinafter particularly claimed will be readily understood from the following detailed description, taken in connection with the accompanying illustrative drawing, wherein the preferred and a modified form of invention is shown.

In the drawing :F igure 1 is a vertical section through the burner showing the preferred form of the attachment in side elevation. Fig. 2 is a vertical sect-ion on the line 2-2 of Fig. 1. Fig. 3 is a perspective view of the attachment disassociated from the burner. Fig. 4 is a similar view of a modification.

In the drawing an ordinary lamp burner is shown comprising in general the burner cone 1, hinged to the base 2 and provided with the usual foraminous base plate 8, within which parts are mounted the wick tube 4 containing the Wick 5.

The attachment forming the subjeot-matter of the present application comprises a blank of sheet metal cut out and bent to form oppositely disposed upwardly converging plates 6 and 7 ,,having downwardly divering legs 8, the two plates connected at their ends by Webs 9 provided in the medial portion of their inner edges with notches 10. The attachment is also advantageously provided between the legs 8 with resilient arms 11 inwardly extending from the two plates 6 and 7.

The attachment is adapted to be placed within the burner cone and about the wick tube, as shown in Figs. 1 and 2, the resilient arms 11 bearing from opposite sides against the wick tube and the two notches 10 of the webs 9 engaging the edges of the tube, whereby lateral displacement of the attachment with reference to the wick tube' is avoided. The attachment is supported vertically by its legs 8 resting upon the for-aminous ventilating base plate 3.

It will be observed by an inspection of Fig. 2 that the two plates 6 and 7 occupy positions upon opposite sides of and equally spaced from the wick tube and extending from a position some distance below the top of the said tube to a point slightly above the same. It will also be observed that the passage of air upwardly from the ventilating plate 3 about the wick tube between the plates is unobstructed, so that the air supply to the burner through the plate 3 is divided by the attachment into two portions, one passing adjacent to the wick tube through the attachment and the other outside of the attachment, the first portion being supplied first to the flame at the wick and the second portion supplied later at a point above the wick.

The position of the two plates relative to the tube is such that the heat from the flame is deflected against said tube in its upper portion, whereby the oil in the wick adjacentthe point of combustion is highly heated and more completely gasified than has heretofore been usual. The air supply to the flame at the end of the wick is also caused to pass through this superheated space and is supplied to the flame in a more highly heated condition than would otherwise be the case and at a higher temperature than that of the air supplied to the flame in its upper portion.

The resilient arms 11 may be dispensed with, as shown in Fig. 4, although where used they serve as an additional means of transmitting the heat from the plates 6 and 7 to the burner tube 4:.

Many attempts have heretofore been made to improve the combustion of the oil in lamp burners so as to do away with the objectionable odor and smoke consequent upon imperfect combustion, but such attempts have usually been embodied in forms of construction which involve a changing of the burner itself or in an attachment which directly modified the form of the flame or interfered with the supply of air to the flame.

In the present invention are combined the important features of superheating the wick tube in its upper portion without unduly heating the lower portion thereof or the oil in the fount, and also the modification of air supplied to the flame, so that the air supplied to the flame at its lower portion is warmer than that supplied to the outer portion, both being unrestricted. Also the invention provides for the protection of the flame laterally from side drafts due to the violent blast of air upwardly through the ventilating plate occasioned by the opening of a window or door, it being observed that the air passing through said plate and impinging upon the wick is directed vertically thereof, while the outer currents of air are only permit-ted to flow laterally after they reach a point above the wick.

The attachment is one which is very inexpensive, may be instantly placed in position upon any lamp, is invisible when in use and is very effective to produce and maintain perfect combustion and high illuminative value.

WVhat is claimed is 1. An attachment for lamp burners comprising upwardly converging horizontally parallel plates connected at their ends only by transversely notched webs and provided with downwardly diverging legs and with inwardly extending resilient arms intermediate of said legs, the attachment adapted to surround the wick tube with its legs resting upon the perforated base plate of the burner with the notches of its webs in engagement with the end of the wick tube and with the resilient arms bearing against the sides of the tube and. with its plates in spaced relation and parallel to the tube as viewed horizontally.

2. An attachment for lamp burners comprising upwardly converging horizontally vparallel plates having their ends connected by transversely notched webs and provided with legs, the attachment adapted to be placed within the burner about the wick tube with its legs resting upon the perforated base plate of the burner and with the notches of its webs in engagement with the end of the wick tube and with its plates in spaced relation and parallel to the tube as viewed horizontally, the height of the attachment being such that the plates extend from a point considerably below the top of the wick tube to apoint slightly above the top of the wick in its normal position.

In testimony, that I claim the foregoing as my own, I have hereto a'flixed my signature in the presence of two witnesses.
