RFUS MILTON MERRILL, OF CHICAGO, ILLINOIS.
IIIVIPROVED LANTERN-LAM P.
Specification forming part of Letters Patent No. 35,382, dated May 27, 1862.
4a full and exact description thereof, reference being had to the accompanying drawings, and
to the letters of reference marked thereon.
Thenature of my invention consists in the application of one or more air-passages to the lantern-lamp in such a manner as to allow air to enter at the bottom of the lamp and escape close to and below the flame for the purpose of preventing the extinguishment of the dame by sudden movements given to the lantern.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
Figure 1 is-a vertical section of a lantern i lamp containing one air-passage.A Fig. 2 is a horizontal section ofit through c. Fig. 3 rep; resents a vertical section ol a lantern-lamp containing two air-passages. Fig. 4 is a horizontal section of it through S..
I construct my lantern-lamp in any of the known forms and apply thereto the tube or `pipe N, with its openends, Fig. 1, extending from the center of the lamp-bottom o o up through the top part, H H, of the lamp and fastened Water-tight to bottom o o and top H H. The upper end of the tube N is covered with a conical or tapering Wire-gauze cap,t, to check the air-current rushing through tube N in the direction of the arrow q,whenever the lantern is lowered suddenly.
To the lamp-top H H, I apply two converging wickguides, V V', with their wicks W W, the latter meeting at the point where combustion takes place. The opening X through the lamp-top H H is to supply the lamp with oil or other fluid.
The operation of my invention is as follows: Suppose the lantern should receive a sudden downward motion, the air passing up through pipe N will be checked by cap t and ldispersed through the whole lantern so as not to extinguish the iame. The very same object is effected by the arrangement represented in Fig. 3, which varies from the one just described only in so far as it contains two air-passages, N N', instead of one.
What I claim as my invention, and desireto secure by Letters Patent, is-
Not only the application of one or more airpassages through a lantern-lamp and its bottom, substantially as described and for the purpose specified, but also the application of one or more airpassages through a lanternlamp and its bottom, substantially as described and'for the purpose specified, in combination with an air-current checker, for the purpose set forth.
