1 Application filed February 14, 1883: (No model.)

To all whom it may concern:

Be it known that I, \V. HARRISON ALBAOI-l,

of hilansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Fruit-Evaporatms; 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 pertains to make and use the same.

7 My invention relates to an. improvement in fruit-eva-porators, the object of the same being to provide a device of this character which shall combine simplicity and economy in con struction with durability and efficiency in use; and with these ends in view my invention consists in certain details in constructionv and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in front elevation of my improvement, showing the doors open. Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a plan view of the heating chamber, and Fig. '4 represents a perspective view of the heating chamber with its sections discoir nected.

A represents an outer structure of any suitable size, and preferably rectangular in shape, and having a slanting roof, which can be provided with ventilators or not, as desired. This structure can be made of anysuitable material, preferably wood, and is provided in front with doors B, each of which latter is divided transversely, thereby forming two doors to the side, and enabling the lower doors to beopened without subjecting the fruitchamber to cold drafts. This outer structure is made slightly larger than the inner structure, so as .to form an air-spacebetween the fruit-chamber and hotair chamber and the building A, and the lower sections of the doors B are each provided with the small doors 0, which latter, when the doors B are closed, rest opposite the door in the hotair chamber, so as to afford a passage-way to the doors of the furnace without opening the large doors B. l

The inner structure consists of the fruitchamber I) and the hot-air chamber E, the latter being situated under the former and in direct communication therewith. The fruitchamber Dis also preferably rectangular in shape, and is made either of zinc or other sheet metal, covered or lined with asbestos,

thelieat generated in the furnace to the inner structure. This fruit-chamber can be formed with one or more compartments, each of which is provided with the slides or flanges a, on which the trays rest, and each tray is provided with a closed face, I), which latter, when all the trays are in position, close the front of the fruit-chamber, thereby preventing the fruit in the trays from being exposed to the outside atmosphere when the doors B are thrown open. The fruit-chamber l) is provided with a top made of perforated metal or boards, and with a bottom made of wire screen, which latter, besides being a uniform radiator of heat, also prevents any fruit from falling through into the hot-air chamber. The fruit-chamber is removably placed on the top of the heatingchamber, and is supported partly thereby and partly by the standards (I, which latter are situated under the four corners of the fruitchamber. The heating-chamber E is made of detachable sheet-metal sections,which enables it to be taken apart for storage or transportation. Each section is made of zinc or sheetiron, orothermetalcovered or lined'with asbestus, so as to retain the heat therein, and

like chamber is formed on which the fruitchamber rests. The object of using asbestus as a lining and covering for the heating-chamber is because of its indestructibility, the na thin layer will last a very long time, thereby avoiding the inconvenience of a heavy thick coating, which would be the case if brick, cement, or similar material were used. I would not therefore have it understood that I lay claim to or desire to employ cement, fire-clay, or plaster-of-paris. Two of these sectionseither the front and rear or the two sides-are provided with outwardly-projecting tongues a, while the sides of the other two sections are flanged, so as to overlap the edges of the adjacent sections. The flanged sections are also provided with oblong slots i, adapted to register with the'tongues 'n of the adjacent sections. hen it is desired to secure the parts together, the tongues of one section are passed both of which are non-conductors, and confine k when the parts are secured together a hopper-.

.ture of this mineral being such that a veryview.

.and then the last section is placed and secured in position, forming a strong and durable chamber, well adapted for the purpose in When it is desired to take the chamber apart for storage or transportation, the tongues a are bent out straight and the parts separated without the use of any costly tools or skilled labor. One or more of the sections of the chamber are preferably provided with draft openings and regulators.

The fruit-chamber can also be made up of sections and secured together in a similar manner to the heating-chamber.

J is the furnace, of any suitable size and construction, situated in the hot-air chamber immediately under the fruit-chamber. This stove or furnace restsup close to the front vertical wall, (I, which latter is provided with a door which registers with the stove-door, and also with the small doors 0 in the outer chamber.

The stove-pipe K passes through the wall of the hot-air chamber and through the outer structure, and then passes upward on the outside of the building, and is again connected therewith by the small pipe L, which latter is situated above the fruit-trays and serves to. ventilate both structures.

To prevent dust or smoke from passing upward between the fruit-chamber and the outer structure, A, when the furnace-door is opened for the purpose of adding fuel, I secure a partition, M, to the outer side of the hot-air chamber, above the furnace-door, and extend the same outward to the walls of the outer chamber. This partition or roof, in connection with two vertical walls on opposite sides of the door, forms a box or passageway, through which ingress is obtained to the furnace and egress for the dust and smoke that passes through the stove-doors. The outer and inner structures can be slightly elevated on any suitable foundation having opening for the free entrance of air, or they can be provided with draft-regulators, as desired. I prefer .to employ the draft-regulators, as they enable me to better control the temperature of the evaporator, and obtain a more perfect ventilation without subjecting the fruit to cold drafts. To illustrate, supposing the wind is blowing from the west, I would open the draft-regulator on the west side of the outer structure and on the east side of the hot-air chamber, all the otherdraft-openings being closed. This would necessitate the air making a half circuit around the hot-ail" chamber, during which time it wouldbecome heated.

By making the heatingchamber and fruitchamber removable the outer structure or building can be utilized for other purposes when convenient, and by making the chambers separable they can be packed in small compass for storage and transportation.

These evaporators can be made for family use and of such size to be used on an ordinary stove. In the latter instance a hot-air case .and fruit-chamber only would be employed.

Myimprovement is simple in construction, durable and effective in use, requires very little attention, and can be manufactured at a small initial cost.

' It is evident that slight changes in the construction and relative arrangement of the several parts might be resorted to without .departing from'the spirit of my invention, and hence I would have it understood that I do not limit myself to the exact construction of parts shown and described, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a fruit-evaporator, the combination, with an outer structure provided at its lower end with vertical corner posts, of a heatingchamber inclosing the furnace, and having its upper portion hopper-shaped and provided with flanges to rest upon said ,posts, and a fruit-chamber having a wire-screen bottom extending over the hopper portion of the heating-chamber and adapted to be removably secured upon said chamber, substantially as set forth.

2. In a fruit-evaporator, a heating-chamber consisting of independent sections provided with slots near their corners and tongues projecting from their edges, said tongues being adapted to enter said slots and to be bent, whereby the sections are secured together, substantially as set forth.

3. In a fruitevaporator, a heating-chamber consisting of independent sections, one of which is provided integrally with a passage, M, said sections being each provided with slots and tongues, the latter being adapted to enter the slots and be bent to secure thesecr tions together.

, 4. The combination, with an outer structure or'building and an inner fruit-chamber supported upon offsets from the frame of the building, of the hopper-shaped heating-chamber constructed substantially as described, and lined or covered with asbestus, and situated under the fruit-chamber, and a stove or furnace located under the heatingchan1ber and inclosed within the casing of the hopper, sub stantially as set forth.
