Description
UNITED STATES PATENT OFFICE.
RUFUS M. MERRILL, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN LANTERN-LAM PS.
Specification forming part of Letters Patent No. 36,570, dated September 30, 1862.
To all whom it may concern:
Be it known that 1, Bonus M. MERRILL, of Ohicag0,in the county of Cook and State of Illinois, have inventeda new and Improved Lantern-Lamp; and I do hereby declarethat the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part'of this specification, in which Figurel is avertical section of my invention, taken in the linew :r, Fig. 2. Fig. 2 is a plan or top view of the same through the line It.
Similar letters of reference indicate corresponding parts in the two figures.
This invention relates to animprovement in lantern-lamps for burning coal or other oils; and itconsists in a novel arrangement of tubes or air-passages,as hereinafter fully shown and described, whereby the flame is supplied with the requisite quantity of air in a manner to insure combustion when a sudden motion is given to the lantern and thus prevent its being extinguished.
To enable others skilled in the art to fully understand and construct my invention,I will proceed to describe it.
I construct my lantern-lamp in any of the known forms and apply thereto the tubes-0r air-passages O G, with their open ends, the lower ends fitting closely in openings in the lamp-bottom B and extending upward a suitable distance outside of the fount or oil-cup A, the upper ends of the tubes 00 being curved in such a manner as to give the currents of air passing through them the proper directions to insure combustion when thelantern is lowered suddenly.
D D are spring-catches which are secured at their lower ends to the side of the external casing or frame, F, and, extending upward nearly to the tup,are bent,and,passing through slots in the casing,terminate with hooks or catches e e,by which the upper portion of the lantern is fastened to the lamp or lower part.
The operation of myinvention is as follows: Suppose the lantern should receive a sudden downward or swinging motion. The rarefied air within,rnshing out ofthe top or sides, will'be replaced by fresh air passing th rough the tubes, which give it the proper direction to bring it in direct contact with the flame and prevent it from dying down or being extinguished. The
RUFUS M. MERRILL.
