CHARLES E. BURNASH, OF VILLANOVA, NEW YORK.

FRUIT-DRIER.

SPECIFICATION forming part of Letters Patent No. 247,159, dated September 20, 1881, Application tiled March 10, 1881. (No model.)

To all whom it may concern:

Be it known that I, CHARLES B. BURNASH, a citizen of the United States, residing at Villanova, Chautauqua county, and State of New York, have invented new and useful Improvements in Fruit-Driers, of which the following is a specification.

My invention relates to the details of construction of a fruit-drier having a series of tray-carriers adapted to be revolved about a horizontal shaft within an evaporating-chamber, beneath which a suitable furnace is arranged, the object being to provide a fruitdrier for domestic use having more than the ordinary area of drying-surface compared with the size of the apparatus, and one which is portable and comparatively inexpensive.

In the drawings forming part of this specification, Figure 1 is a perspective view of my improved fruit-drier, having its main door open and one side broken away to show a part of.its interior, some of its tray-carriers being left off from the wheel to show more clearly the parts beneath the latter. Fig.2 is a side elevation, partly in section. Fig. 3 is a front elevation. Fig. at is a plan view through the dotted line, Fig. 2, a part ofa deflector therein being broken away to show parts under it. Fig. 5 is a front elevation of the lower front side of the machine,

in which the outer jacket is broken away to.

show the location and arrangement of the furnace therein.

In the drawings, A is the outer jacket of the drier. b is a ventilating-pipe leading from the dryingchamber. c are tray-carriers. e are the fruit-trays. d are tray-carrier arms, mounted on a shaft, f, and to which, as shown, said traycarriers are pivoted at each side, and said shaft is adapted to revolve in suitable hearings in the jacket A. g is a shaft, having a worm on one end and a crank secured to the other, as shown, and is properly supported on the side of the machine. dis a gear on shaftf. n is the main door. 0 is the furnace-door. 0 is the furnace. sis the furnace-pipe. o is thejacket surrounding the furnace 0, to which the furnace is secured at its ends by suitable flanges, as shown. 50 is the bottom of the drier, under the furnace. m is the bottom of the evaporatingchamber D, having two series of rectangular those in the bottom m.

openings, at, therein, as shown in Fig. 2, and in dotted lines in Fig. 4-. w w are sliding dampers lying upon bottom m, and having openings of rectangular form in them, as shown, and handles 2 attached to them, which operate through the outer jacket, A. 2 2 are air-deflectors set over and a little above the dampers w, and havin g openings 3 therein. E is an inner wall, set upon the bottom m of the chamber D so as to leave an air-space, 5, between it and the jacket A, and through the bottom m, at the bottom of said air-space 5, is a series of air-holes, 6.

An entire metal construction is best adapted to the purposes of my machine.

The top of thejacket A is inclined, as shown in Fig. 2, to aid the free movement of vapors in chamber D toward the ventilating-pipe b. The bottom m to chamber D has two series of air-passages through it, as above describedviz., a and 6. Over said openings a are placed two sliding dampers, to, also provided with openings similar to openings at in bottom m, and arranged in the usual manner, so that by sliding said dampers, by taking hold ofhandles z, the openings in the dampers and in the bottom may coincide and allow air to pass up through, or the said dampers may close the openings in the bottom m, shutting off the'air entirely.

A deflector, 2, is secured to the side of wall E, over each of said dampers, and provided with openings 3, which do not coincide with Said openings in the deflectors 2 are so arranged for the purpose of preventing currents of warm air from rushing directly up against the trays e in the chamber D, and to disseminate said currents around said chamber.

An opening, 7, is made in the lower bottom, 00, and one corresponding to it is made in the lower and upper sides of the furnace-jacket 'v, to allow air to pass from below around the furnace 0, become heated, and pass up under and through the bottom at into the chamber D. Upon shaft f, hung as aforesaid in proper bearings, are secured the tray-carrier arms 01, and the tray-carriers are hung thereto, as shown, so that as said arms are revolved the carriers will swing between said arms, always carrying the trays level. Said tray-carriers are adapted to receive several trays, e, upon proper cleats at each end. Said trays are made of wire-cloth or other suitable porous material, and are not secured to the carriers 0, but simply laid upon said cleats. A gear, 43, secured upon the end of shaft f, and a worm-shaft, 9, whose worm engages with said gear, provide means for revolving said shaft and the tray-carriers within chamber D.

By revolving the tray carrying arms, as above described, each of the carriers 0 may be brought successively before the door a for removing from and replacing trays thereupon.

The operation of my machine is as follows: The furnace 0 is supplied with suitable combustibles to generate the requisite heat and air passing up through the bottom 00, through the opening 7 therein, circulates around the furnace, between it and the jacket 02, and, becoming heated, passes up through the openings a and 6 in said bottom. Said air-currents which pass through the openings in the dampers and through those in the deflectors 2 are regulated as heretofore described. Those which flow up through the space 5 pass directly to the upper part of chamber D. The fruit to be dried, or from which the moisture is to be evaporated, is spread upon the trays 0. One of been loaded, when the door is shut, and by turning shaft 9, either by hand or by suitable clock-work, the tray-carriers, with their load of fruit, are successively exposed to the action of the more direct warm currents of air at the bottom of chamber D, but are not allowed to there remain so long as to let the fruit become injured by too great heat, and thus, in a short time, the fruit becomes evenly and thoroughly dried.

What I claim as my invention is In a fruit-drier, the combination, with the evaporating-chamber D, of the furnace 0, the Wall E, and bottom m, having the openings (0 and 6 therein, the sliding dampers w, the de fiectors 2, the tray-carriers c, trays e, the traycarrier arms d, shaft f, and appliances, substantially as described, for revolving said shaft, substantially as and for the purpose set forth.
