To all whom it may concern:

Be it known that I, DANIEL Bonn, a citizen of the United States, residing at Milford, in the county of Kent and State of Delaware, have invented certain new and useful Improvements in an Apparatus for Drying and Conserving Fruits; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the or heated air, or both together, are used for heating the dryingchambers, and the appara tus is adapted either to drying or conserving fruits, and whereby different chambers may be heated and treated diiferently at will.

I employ a set of drying-chambers, A A, of any suitable or desired construction,iornr, and size, and they may be placed one on top ofanother and side by side, as many as desired, the arrangement shown in the drawings being a suitable one. These chambers are nearly or quite air-tight, and their doors a a fit closely. The fruit-trays Z) I) in them may be placed quite closely, one above another, to obtain as much drying surface as possiblc. These dryingchambers are mainly heated by a steam pipe or pipes, B, which extend and double or coil under each chamber, so as to present as much heatingsurface as necessary to obtain therequisite heatingpower therefrom. The pipe B, after extending to and coiling or doubling under the several drying-chambers, may enter a condensed-steam chamber, 13, from which the water from the condensing of the steam is drawn through a pipe or spout.

Auxiliary to the heating steam pipe or pipes B, I employ a hot-air pipe or pipes, G, which communicate by branches 0 c with the interiors of the several drying-chambers, so as to admit the dry heated air from the pipe or pipes into the chambers. One furnace having a lieatingchamber, D, suffices to generate the steam for the steam pipe or pipes, andto heat the air to pass through the hot-air pip e or pipes, the steam-coil itself heating the air before it passes through the said hot-air pipe or pipes. Also from the interior of each drying-chamber an exhaust-pipe, E, leads through short branch pipes d d, connecting with the several chambers. Au exhaust-fan or air-pump, G, is connected with the other end of the exhaust pipe or pipes for drawing through the said pipe or pipes the air and moisture or vapor from the dryingohainbers, so as to continually have dry air in the said chambers for drying the fruit. Each connecting branch 0 of the hot-air pipe or pipes O is provided with a stop-cock and valve, f, to exclude the hot air, wholly or partially, as de sired, and each branch exhaust-pipe d is similarly provided with a stop-cock, 9, so that any one or more of the chambers may be cut outfrom action when desired. Thus each chamber is made independent of the others.

hen the fruit is to be dried in a chamber or chambers A, more or less of the heated air is admitted through the hot-ai r pipe to increase the rapidity of the dryin When the chambers are used for conserving fruit, nohot air is admitted, since that would shrink the fruit, which is to be avoided.

I also provide for admitting steam from the steam pipe or pipes B into the several cham bers A A through branch pipes 1', each having a stopcock, k, to admit the steam or not. This may be especially useful in conserving fruit where a dry atmosphere is not desired.

\Vhat I claim as my invention is- 1.. In an apparatus for drying and conserving fruits, the combination of drying or COHSGIW ing chambers, steam heating pipe or pipes leading to the several chambers, hot-air pipe or pipes communicating with the interior of the several chambers, means for forcing heated air through the hot-air pipe or pipes into the said chambers, and valves for controlling the flow of hot air into the several chambers, for the purpose herein specified.

2. In an apparatus for drying and conserving fruits, the combination ofdryi ng or conservthe purpose herein specified.
