SPECIFICATION forming part of Letters Patent No. 365,752, dated June 28, 1887.

Application filed August 2 5 1886. Serial No. 211,665.

To all whom it may concern:

Be it known that I, Sara W. LOWELL, of Belfast, in the county of Allegany and State of New York, have invented a new and Improved Evaporator, of which the following is a full, clear, and exact description.

My invention relates to the construction of an evaporator designed more especially for use as a fruitdrier; and the invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figurcl is a front elevation of my improved evaporator or fruit-drying apparatus. Fig. 2 is a sectional plan view of the same, the view being taken on linear 0c ofFig. 1. Fig. 3 is a central cross-sectional elevation, taken online 3 y of Fig. 1; and Fig. 4: is a detail view illustrating the construction of one of the expanded U couplings.

In constructing such an evaporator as is illustrated in the drawings above referred to, I provide an inclosing-case, A, one side of which is open. A hood, B, is arranged above and at the rear of the case A, said hood leading to a fine, 0, in which there is arranged a damper, D, whereby the draft of the said flue is regulated.

Vfithin the chamber formed by the walls of the case A there are arranged a number of steam-pipes, a a a, said pipes beingunited in sets, asE F G, by U couplings I), and one ofthe pipes of the series G is connected with one of the pipes of the series F by an expanded U coupling, H, while'the series F is put in communication with the series E by asimilar eX pandcd U coupling, 11. The pipes of the lower series, E, are supported upon blocks N, which rest upon the base of the case A, while the pipes of the two series F and G are supported by blocks N N, as shown in Fig. 1. The couplings H 11 are made up of elbows 2, formed with flanges 3 or 4, the peripheral face of the flange 3 being threaded to engage with the union 5, and the meeting faces of the flanges are grooved, so as to fit closly together.

From the construction described it will be seen that the several series of pipes may be taken [No model.)

apart. The inner pipe of the up'perserics, G. is led out through one end of the case A and connected with a steam-supply boiler, while the forward pipe of the lower series, E, is led out to be properly connected as the dischargepipe of the system. All of the outer pipes, a, carry sleeves is, formed with arms I, which project inward toward the longitudinal center of the pipes, and serve as supports for crossstrips a, the inner ends of which are supported by clips 76, and these strips 02 in turn serve as supports for sheet-metal plates 0. It will be noticed that the space directly beneaththe hood B is unencumbered by steam-pipes, the idea being to permit of a free circulation of air; but in order that the air may be carried overthe surface, instead of up between the pipes at, I have arranged screens or plates, as described, and a board or partition, It, that is fixed within the case A, beneath the lower series'of pipes. The fruit to be dried having been properly prepared is placed in trays that are set upon the upper faces of the pipes, and as the moisture of evaporation rises from the fruit it is carried to a point directly beneath the hood, and is finally carried upward and out of the due 0; but it will be readily understood that the vapor from the lower pans cannot possibly come in contact with the fruit contained in the upper pans or trays owing to .the interposition of the plates 0. The plates 0 are made so that they can readily be removed, in order to free the apparatus from such debris as may and necessarily will fall upon the plates.

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

1. In an evaporator, the combination, with the sections of st'eanrpipes and the case therefor open at one side, of inclined deflectingplates removably connected to the under side of each section and adapted to be inserted and removed through the open side of the case, substantially as set forth.

2. In an evaporator, the combination, with the casing, of the vertical series of sections of detachably-connected horizontal steam-pipes, and an im perforate deflecti rig-plate removabl y secured to the under side of each section, whereby a section of pipes with its deflectingplate may be removed together at any time,
