TUBULAR LANTERN.

Application filed February 23, 1910.

To all whom it may concern:

Be it known that we, CLAYTON T. TI-I11- PLE, residing at Glens Falls, in the county of Varren and State of New York, and Hannnn'r A. Moonr, residing at Sandy Hill, in the county of ashington and State of New York, citizens of the United States,have invented certain new and useful Improvements in Tubular Lanterns, of which the following is a specification.

This invention relates to tubular lanterns and particularly to the tubes and burner collar of said lanterns, the object of the invention being to provide an improved burner collar for attachment to the font, said collar forming an air chamber, and also to provide improved means for connecting the collar to the air tubes, and furthermore an improved method of seaming the collar to the font,

without the use of solder.

The invention embodies the formation of the burner collar in two halves integral with the halves of the lower elbows of the air tubes, said elbows being connected to the upright parts of the air tubes. Heretofore it has been the practice to make the lower elbows integral with the standing part of the tubes and solder the ends of said elbows in holes in the burner collar. This results in considerable waste of metal, in stamping the tubes. By making the lower arms of the tubes integral with the collar this waste is to a large extent avoided, the parts may be more quickly assembled, and the use of solder is unnecessary.

The invention is illustrated in the accompanying drawings in which Figure 1 is a side elevation of the lower part of a lantern containing the improvement. Fig. 2 is a section thereof.

Referring specifically to the drawings, 6 indicates the font, the top of which has a central opening at 7 at the top of a slightly conical part pressed therein. The edge at this opening fits in a groove in the burner support 8 which extends into the opening and is thus supported. The wick tube 8 is made in a separate piece and depends into the font from the lower end of the burner support, the rim of the wick tube being flanged into the groove mentioned. A circular indentation 9 is made in the top of the font, at the base of said conical portion, forming a groove to receive the lower edge Specification of Letters Patent.

of the burner collar 10 which forms an air chamber supplied through the air. tubes. The edge of the burner collar is set in the groove which is then rolled by pressure, expanding and fastening the edge of the collar in the groove. The burner cap 11 tits at its lower end on a neck 12 at the top of the collar.

The burner collar 10 is made of two halves or pieces of sheet metal each of which is integral with the halves of the lower arms or elbows 13 of the air tubes, the parts being joined together by longitudinal seams at- 14, to complete the collar and elbows. The standing or upright parts 15 of the air tubes are similarly made of joined halves, and they are joined to the elbows by a one or more bead and groove joints at 16, which joints may be made without the use of solder. A tight seam at the groove 9 between the lower edge of the burner collar and the top of the font is made by pressing the sides of the groove together upon said edge, which is thus gripped under the overhanging or upper wall of the groove so that a tight seam is formed. The halves of the burner collar and tube elbows are pressed and stretched to proper shape by suitable machines for the purpose, and when assembled the arms of the tube rest on top of the font. This construction avoids the objectionable waste incident to stamping the complete tubes and their elbows from the same sheets of metal, and also avoids the necessity for a soldered oint between the tubes and the burner collar and enables the parts to be readily assembled and connected to the font in proper position ,to receive the burner cap and wick tube.

We claim 1. In a tubular lantern, the combination of a font having an opening in the top, and a groove in said top at a distance from said opening, a wick tube and burner support extending through said opening and supported by the edge of the top at said opening, and a burner collar the lower edge of which is fitted into said groove and expanded under an overhanging part thereof.

2. In a tubular lantern, the combination of a font, a burner collar and tube elbows attached thereto, said collar and elbows being formed of two side parts united by longitudinal seams in a vertical plane, and air tube sections joined to the outer ends of said elbows.

3. In a tubular lantern, the combination of a font, and a burner collar and tube elbows connected thereto, said collar and elbows being formed of two parts united by longitudinal scams 4:. In a tubular lantern, the combination of a font, and a burner collar mounted thereon, said collar being formed of two semi-circular parts, each part having integral there with projecting halves of the lower elbows of theair tubes, said parts and halves being united to form the complete collar and elbows.

5. In a tubular lantern, the combination of a font having an opening in the top, the burner support tube 8 extending through said opening, said tube having a groove! CLAYTON T. VVI-IIPPLE. HERBERT A. MOODY.
