UNITED STATES PATENT OFFI E.

ARTHUR ooNDLY PENNIMAN, or sAN JOSE, CALIFORNIA.

FRUlT-EVAPORATOR.

' SPECIFICATION forming part of Letters Patent No. 349.450, dated September 21, 1886.

Application filed March 13, 1886. Serial No. 195,090. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR CoNDLY PEN- drawings, forming thereof a part, in which Figure 1 is a sectional elevation of my improved evaporator on the line as as, Fig. 2, the

furnace being removed. Fig. 2 is a cross-sectional view on the line y 3 Fig. 1.

Corresponding parts are denoted by similar letters in the different figures of the drawings.

My invention consists in placing tubular cross-bars on the bolts connecting the rims of the wheels, and in glazing the upper walls of the oven, as will be hereinafter described and claimed.

The drying-oven A is arranged over a furnace of ordinary or any approved construction, and in suitable bearings in its side walls the shaft B is mounted to revolve.

Within the oven A the large wheels '0 are rigidly mounted on the end parts of the shaft 13, and their rims are united by means of a series of rods or long bolts, D, having nuts screwed on their ends outside of the rims, so as to firmly brace the wheels 0. The rods D are passed loosely through the longitudinallybored cross-bars D, to the ends of each. of which are attached the upper ends of two hangers, E, connected at their lower ends by a brace, E The hangers Eare widened at their lower ends, and are formed with series of transverse ways E, which receive the ends of the fruit-trays F. The fruit-trays are provided with perforated bottoms, as usual, and are maintained in a horizontal position during the revolution of the wheels by their gravity and the pivotal connection of thehangers E, carrying them. Any number of hangers E may be used, provided they do not interfere with each other in their pendulous movement during the rotation of the wheels, and the hangers may be provided with series of ways E, to receive corresponding series of fruit-trays, as shown.

The upper parts of the oven-walls may be constructed of glass, as shown, to permit inspection of the product treated, and the roof of the oven is provided with a slide-damper, G, to regulate the heat therein. v

To concentrate the heat upon the fruit-trays, the oven should be of approximately the same size as the wheels, and access-to the fruit-trays is gained by means of the door H" at the front of the oven. The shaft B'beingslowly rotated by hand or otherwise in the direction of the arrow, Fig. 1, the trays F, containing the fruit to be treated, are introduced through the door H upon the hangers E as they pass in succession by the door.

The fruit-trays are first subjected to the more intense heat at the bottom of the oven,and as the treatment progresses are carried by the wheels to the cooler upper part of the oven, whereby overheating is prevented, and, the desired de gree of evaporation being obtained, the trays are removed through the door H at the end of the revolution and freshly-filled trays substituted. The vaporized juices from one tier of trays mingling with the fruit above, a delicate flavor is imparted, and, the trays being in constant motion and subjected in turn to the same heat, the fruit is dried quickly and uniformly.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- In an evaporator, the combination, with the wheels 0, rigidly mounted on the rotary shaft 13, of the bolts D, passed through the rims of the wheels, and the binding-nuts screwed 011 their outer ends, the tubular cross-bars D,

mounted looselyv on the bolts D, and serving to space the wheels 0, and the penduloustray supporting hangers E, received on the ends of the tubular cross bars D, substantially as shown and described.
