SAMUEL W. HOPE, OF DOVER, DELAWARE.

I IMPROVEMENT IN FRUIT-DRIERS.

Specification forming part of Letters Patent No. 172,740, dated January 25, 1876; application filed October 16, 1875.

To all whom it may concern:

Be it known that I, SAMUEL W. HOPE, of Dover, in the county of Kent and State of Delaware, have invented a new and Improved Fruit-Drier, of which the following is a specification The invention consists in combining certain means for removing moisture from fruit, as hereinafter described, and pointed out in the claim.

Figure l is a sectional elevation of my improved drier. Fig. 2 is also a sectional elevation, and Fig. 3 is a horizontal section.

Similar letters of reference indicate correspondin g parts.

A represents a flue-shaped drying case or chamber, to be made of any approved mate rial, and so constructed as to sit on a foundation-section, B, Which,by preference, will be of brick to the height of the heater, or thereabout, the said dryingflue being constructed in such form and proportion that it will act as a flue for taking up the air to the trays D, and by that means effect the circulation. But, in

addition thereto, and for use in case of need,

I also propose to have a system of small tubes or fines, E, at one or more sides, for taking some of the air up around or by the trays and discharging it into the drying-flue again, between the trays, and also another system, F, for drawing out the air from the spaces between the trays as it becomes charged with moisture by evaporation of the moisture of the fruit, these latter fluesbeing open to the main flue or to the atmosphere at the top, for discharging, and the others, being provided with valves J, to regulate the currents and direct them into the different spaces, as required. In this example the flues of these two systems are arranged alternately side by side; but, in practice, I propose to so arrange them that the same fines may be used to conduct the air from below into the spaces, or from the spaces to the place of escape above, suitable valves or dampers being employed for converting them from the one condition to the other.

The attachment for utilizing the heat escaping from the smoke-pipe K, after it emerges from the Wall of the drying-flue, consists of the hood L, built out around the lower portion of the pipe to catch the rising heated air, and the fiues'or passage M, to conduct the same into the drying-flue.

The roof-plates Nare, in this example, made of metal, for the purpose of condensing the moisture of the air in the drier, so that it will escape by flowing down through passage 0, or may be carried off by gutters suitably arranged; but, in practice, I will construct the whole or any part of the drying-flue of such material or glass, or anythat may be found most desirable. I

Having thus described my invention, I claim as new and desire to secure by Letters lPatent- The combination, with flueshaped chamber A, having heater at bottom, of the trays D and the air-tubes E F, arranged to operate substantially in the manner described.
