Specification of Letters Patent.
Patented Mar. 2, 1915.
Application filed September 15, 1914. Serial No. 861,773.
To all whom it may concern:
Be it known that I, BENNARD H. POMEROY, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Tubular Lanterns, of which the following is a specification.
This invention relates to the construction of the oil pot and air chamber of a tubular lantern and has for its object to simplify the construction of the parts, to produce a strong and reliable structure and to reduce the cost of the same. In this improved construction the oil pot and air chamber are formed of one blank of sheet metal by stamping.
In the accompanying drawings: Figures 1, 2, 3 and 4 are sectional elevations showing different forms of the blank produced by successive stamping operations. Fig. 5 is a sectional elevation showing a slightly modified construction of the air chamber.
In producing this improved oil pot and air chamber, a flat blank of sheet metal is first stamped to the form shown in Fig. 1, in which 10 represents the peripheral wall of the oil pot, 11 the annular top thereof, and 12 a raised central portion from which the air chamber is formed and which has a fiat top 13. In the next stamping operation, which is represented in Fig. 2, the upper portion of this raised central portion is driven down into the lower portion in such manner that the flat top plate 13 is now depressed to the position suitable for forming the bottom of the air chamber so as to stand substantially in line with the top of the oil pot. The central upstanding portion of the blank now comprises an outer substantially cylindrical wall 1 1 and an inner similar wall 15 extending from the upper end of the outer wall to the plate 13. In the next operation, represented in Fig. 3, the upper portion of the upstanding double wall is bent inwardly to form the top 16 of the air chamber, and in the last operation, represented in Fig. 4, the inner portion of this double topis turned upwardly to form a collar 17 on the air chamber, suitable for receiving the burner cone. An opening 18 is formed centrally in the bottom 13 of the air chamber for the reception of the usual burner socket (not shown). This opening may be formed when the air chamber has been completed. As represented in Fig. 5, a collar 19 for the burner cone may be formed separately of a single thickness of sheet metal and secured in the top of the air chamber by solder or otherwise. In this improved construction the peripheral wall and the top of the air chamber are formed of two thicknesses of metal, both formed integrally with the oil pot, whereby a very durable and rigid structure is produced, while the cost of producing the same is greatly reduced, no soldering being required for securing the parts together and joints which are liable to leak being avoided.
thiclmess of sheet metal which are integral with each other.
2. The combination with an oil pot, of an air chamber having its peripheral wall and its top formed of an inner and an outer thickness of sheet metal and having its bottom formed integrally with said inner thickness.
3. The combination with an oil pot, of an air chamber having its peripheral wall and top formed of twothicknesses of sheet metal which are integral with each other and with the oil pot.
4. The combination with an oil pot, of an air chamber having its peripheral wall and top formed of two thicknesses of sheet metal and having its bottom and its double top and peripheral wall formed integrally with the oil pot.
5. The combination with an oil pot, of an air chamber having its peripheral wall, its top and its upstanding collar formed integrally of an inner and an outer thickness of sheet metal.
