Description

JOSEPH S. DENNIS.
Tubylar Lantern.
Patented Feb-27, 1872.
mums-sea WWW UNITED STATES PATENT OFFICE,
JOSEPH S. DENNIS, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN TUBULAR LANTERNS.
Specificatiomforming part of Letters Patent No. 123,980, dated February 27, 1872.
. and inserting one end within the other, whereby but a single circular seam is left to be closed by solder.
The drawing represents an elevation of a tubular lantern containing my improvement, one of the joints being partially cut away to exhibit the method of joining. In the said drawing, AArepresentthe side tubes; B B, the upper horizontal tubes; and O O, the lower horizontal tubes.
It is desirable, in this style of lantern, that the joints between these tubes should be curved, both on account ofthemore graceful appearance of thelantern, andbecauseof the moreimportant fact that the curved joint allows an easier passage for the air; heretofore this curved portion of the tube has been made by stamping it out of tin in two halves, which were soldered together and then soldered to the tubes, making four seams to close by solder.
In the present invention, both ends of the side tubes A A are slightly curved, and the outer ends of the tubes B B O C also curved, so that the joint is formed by inserting one tube within the other, with a sufticient lap, as shown in the drawing, leaving only a single circular scam, (I, which is soldered up, and the joint is complete.
. Claims.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
The curved joint hereinbefore described for the tubes of tubular lanterns, made by curving the ends of the tubes and inserting one within the other, as specified and shown.
