IMPROVEMENT IN DEVICES FOR DRYING AND CONDITI ONING LEAF-TOBACCO.

Specification forming part of Letters Patent No. 196,746, dated November 6, 1877; application filed August 9,1877.

To all whom it may concern:

Be it known that I,'ROBERT DUNLoP, of the city of Louisville, in the county of J eiferson and State of Kentucky, have invented a certain new and useful Improvement in a Device for Drying and Conditioning Leaf-Tobaceo; and I do hereby declare that the fol-- tobacco, and also to produce the required moi sture to put it in proper condition preparatory to the further process of its manufacture; consistin g, first, in -a small cylindrical furnace with a drum or water-tank over it, in connection with a series of pipes, one end of which connects with the water-drmn near the bottom,

while a part of one pipe is formed into loopshorizontally with theremainder, extending beyond the loop, and made to enter, theside of the furnace above the fire, where it is again formed into several spiral coils within the chamber, after which the endpasses out at the side, turned up, and is made to enter the end of the drum above, which drum is also further provided with a discharge-pipe across the end of the water-pans, with branches .at the side over each. pan, arranged withfperforated strainers on the ends, by which meanssufiicient spray'is produced to moisten the atmosphere when necessary to put the tobacco in proper condition for further use.

In the annexeddrawing, A represents the furnace, which may be made in any suitable form.- I is the fire-door, and K is the coil of pipe within the chamber, the object of which is to increase the heating-surface, and thereby heat the water more quickly. J is the flueopening, and B is the water drum or tank over the furnace. G is the supply-opening, and D is the vent-pipe, to which a safety-valve may be'attached, if required. N is the main water-pipe, one end of which connects with the rear end of the water-drum .near the bottom. A part of this pipe is formed into the loops F ina horizontal manner, and may consist of any required. number to produce suflicient heat to dry the tobacco, while the same pipe extends beyond the loops and enters the the endof the water-drum B, thereby forming a free, unobstructed passage for the water from, the drum downintothe coils below, ,where it is heated by fire, which causes aconstant circulation through the pipe coils and. drum; R is-the stop-cock for regulating the flow of water, and L is the discharge-pipe named branches, ing spray to moisten or eondltlon the tobacco when'reqnired.

discharged from thestrainers, which may increased to any j-n'umber required.

. Havingthus fully described the nature and object of this iny-invention, what I claim as new,and desire to secure by Letters Patent, in a device for conditioning leaf-tobacco, is-

lhe discharge-strainers H H, by which spray is produced, in combination with the pipe L, drum '13, and pipe N, with its loops F, coils .K, furnace ,A, and pans G G, as above described, arranged, constructed, and operated substantially as and for the purpose hereinbefore set forth.
