FRUIT-DRIER.

SPECIFICATION forming part of Letters Patent No. 285,018, dated September 18, 1883.

' Application filed June,2G,18S3. (No model.)

To all whom it may concern:

Be it known that I, C. CULLEN, a citizen of the United States, residing at Knoxville7 in the county of Knox` and State of Tennessee, have invented certain new and usefulImprovements in Fruit-Driers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters or -iigures of reference marked thereon, which form a part of this specifica- Athe steam has been condensed in the hollow shelves, the drier so constructed forming, as an article of manufacture, one body independent of and detachable from the furnace, as will be hereinafter more fully set forth.

In the drawings, Figure 1 is a perspective, and Fig. 2 is alongitudinal vertical section cut through the central portion, of my improved drier.

The devices referred to in this application as novel are claimed as improvements in the fruit-driers patented to J. C. Gunn, December 5, 1882, No. 268,399, and to W. Z. Hampton, January 23, 1883, N0. 271,065.

To a boiler, A, and running upwardly, are attached standards a a, -which support at regular intervals aseries of horizontal shelves, one above the other. By means of this construction the sides of the drier are left open, there- -by securing a free circulation of air between boiler below is a central open steam passageway, C. At the upper end of this passageway the steam-exit orifice is contracted7 as at c, in-order that the steam ascendingfrom the 5 5 boiler may be somewhat checked and forced into the recesses I), formed bythe top and bottom surfaces of the shelves. Tater is supplied to the boiler through the supply-pipe d and withdrawn through exhaust-pipe c, the usual 6o faucet, f, being constructed thereupon.

Any flat-top furnace or stove E may be used in connection with my drier for the purpose of heating the water in the boiler.

I am aware that steam-recesses have been heretofore used for the purpose of heating shelves, and that the shelves so heated were placed one above the other. I therefore do not broadly claim these devices.

v I am also aware that steam has been supplied 7o to the recesses by means of pipes connected with the boiler, and that these-recesses have been constructed with dished bottoms similar to those shown in my improved drier; but the steam-pipes, Vacting also as exit-pipes for the escape of water formed by condensation,were located near the outer edge of the dished bottom of the recesses, thereby affording no escape for the water which collects at the lowermost point of the recess; and I am also aware that 8o perforations have been made for the escape of water from the lowermost point of the dished bottom of the recess; but because of the peculiar form of the drier, adopting this system, the water is made to drip down outside ofthe steampipe, thereby causing more or less moisture in `the atmosphere surrounding the fruit on the My form of drier, it will be observed, is made separate from and independent of the furnace, and at the sametime the boiler is connected to the shelves in such a manner as to formthe recessed shelves, boiler, and open passage-Way into one compact body. By means of this peculiar construction I am enabled to manufacture and supply to the trade a complete fruitdrier reduced to its simplest and cheapest form and applicableto any well-known form of iiattop stove or furnace.

I have discovered that the best results are obtained in fruitdrying by providing the recesses with as free a circulation of steam as possible. For this purpose I construct the free central passage-way, as described, unobstructed by smoke-pipes, internal sectional steam pipes, sleeves, or valves.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is*- l. In combination with a iiat-top stove or furnace, the detachable fruit-drier constructed l with open. sides for the purpose of affording free circulation of air, and consisting oi' boiler, hollow steam-shelves, and open central valveless passage-way, substantially as described.

2. In a steam fruit-drier, as described, the central unobstructed steam passage-way and hollow steam-shelves, dished centrally, as set forth, whereby the water from condensation is made to return to the subjoined boiler from the lowermost point of the steam-recess directly through the said central steam passage-way, in the manner substantially as shown.

3. As an article of manufacture, the fruitdrier provided with a boiler and central unob structed passage-way, and constructed separately from and independent of the furnace, for the purposes hercinbefore enumerated.

In testimony whereof I have affixed my signature in presence of two witnesses.
