ticial draft, and other features, all of which we shall hereinafter fully describe.
The object of our invent-ion is to provide a simple and effective fruit-drier.
Referring to the accompanying drawings for a more complete explanation of our invention, Figure l is a vertical transverse section of our drier. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a section on line X X, Fig. 1. Fig. 4 is a section on lineYY, Fig. 1. Fig. 5 is a perspective view of the elevator. Fig. G is a sectional view of the spring-catch. Fig. 7 is a perspective view'of the fruit-tray.
A is the shell of the drier. located in its base.
C are return lines, which are separately con nected with the rear of the furnaceechamber by pipes b. These tlues pass through the front wall ofthe shell, as shown in Fig. 2, and are supposed to unite in a suitable smoke-stack. (Not here shown.) Across the shell, horizontally, is fixed a partition or diaphragm, D, whereby the air-chamber d is formed below. Cold air has access to this chamber through openings a, made in the sides ot' the shell, which openings communicate with curved passages a', formed around the lues C by the plates f, as shown clearly in Fig. 1, in which the entrance of the air to the chamber is indicated by the inleading arrows. The diaphragm or partition D has a number of apertures, d', made through it, which are controlled by Valves, di, Fig. 3, in the nature of dampers, by the adjustment of which the air passing from the chamber d through the diaphragm is regulated and controlled.
Theinterior of the shell above the diaphragm is divided longitudinally by a vertical parti- B is the furnace,
tion, E, and transversely by vertical partitions F into any number of chambers, f, as shown in Fig. 2. These are fruit-chambers, and receive their hot air through the valved diaphragm below, their discharge being through individual stacks G, (shown in Fig. 1,) the upper ends of which are controlled by valves or gates g, operated in any suitable manner, as by the cords g. Access to these chambers j is had through feed-apertures H at their base, which admit the fruit-trays, and through door-controlled apertures h in the side walls above, inspection and discharge of their contents may be effected.
Just below the entrance or feed apertures H is a shelf, 7L', to which is hinged a spring actuated inclined flap-door, h2, which normally closes the feed-aperture, as shown in Fig. 1, but which yields to the pressure of the tray when being inserted and immediately closes again. Rollers 7L are located upon the upper end of the door, by which the friction of the tray is avoided. I is a shelt upon which the operator stands in feeding the drier. J are hinged gates for affording access to regulate the valves in diaphragm D.
In each fruit-chamber f is an elevator, K, (shown particularly in Fig. 5,) consisting of a light frame-work, to the upper portion of which is connected a rope or cable, It', passing over guidepulleys k', Fig. 1, and attached to pivoted levers k2, bythe operation of which the elevators are raised and lowered. L is a fruit-tray. (Shown particularly in Fig. 7,and indicated in Fig. lby dottedlines.) This tray is pushed in over the door, through the feedaperture H,and is seated upon the elevator K.
In the side walls of the fruit-chambers are located the beveled catches M, Fig. 6, which are influenced by springs m to remain normally projected. There are two sets of these catches, as shown in Fig. 1.
The edges of the trays L, Fig. 7, are provided with beveled notches l, so that when the elevator is raised the notches of the tray engage the catches and force them back to allow the tray to pass, the catches springing out under and supporting it when the elevator is Withdrawn.
The particular object of the notches Z we shall hereinafter explain. Between the stacks G ofthe frnit-chambers is set a horizontal Wall IOO . through the apertures a in the base of the shell, and passes through the passages c', encircllng the return-fines C,jand is therebyA heated. Entering the airchamber Lit passes up through the valved partition or diaphragm D in such quantities and in such directions as may be desired, and is completely under control, so that it may be admitted to one or more or all of the fruit-chambers f, the proper adjustment of the dampers of the diaphragm being effected through the side gates, J. A fruit-laden tray, L, is passed through the feedapertures H, the spring-actuated hinged door yielding to its passage, and is seated upon the elevator K in the fruitchamber. v By the movement of the lever 7a2 the elevator is now raised until its tray has passed the lower set of catches, M, when the elevator is lowered again, the tray remaining and being supported upon the catches. A second tray is now inserted A into the fruit-chamber and seated onthe elel sition, and it in turn raises the other two and` is'supported upon the catches.
In Fig. l we have shown by dotted lines three trays, one above the other, supported upon the lower set of catches,while the fourth is seated upon the elevator and ready to be raised. These trays tit quite snugly in the fruit-chambers, and resting ,directly upon one another their frames form the walls of vertical flues, through which the heated air is passed, thus effectively drying the fruit resting upon them. Ihe upper trays in each chamber are thus gradually brought to the top and their fruit completely dried, so that they may be withdrawn to make room for fresh ones below,
the entire process being thereby rendered'continuous.
The objectof the notches Z in the frame of the trays is to allow the uprising tray to come in contact with the under surface of the one above and raise it off the catches lbefore its own frame comes in contact with said catches and attempts to force them back. In this way the weight is completely removed from the catches before they are forced back, thus providing for their easy operation. rIhe employ ment of a second set of catches above the first provides for the examination of the fruit after it has passed a given point in the trip upward. The gates g on the top of the stacks G enable us'to control the draft. It may be found that the natural draft Will not be ,sufficient to remove the damp air which usually collects in the top of the fruit-chambers; but to provide for thiswe connect all the chambersfthrough the apertures a with the longitudinal passage n, and thus by the operation of the suctionblower O at the end ot' t-he passage are enabled to provide for an artificial draft, which may be used either alone or to supplement the natural draft.
Having thus described our invention, what we claim as new, and desi re to secure by Letters Patent, is-
1. In a fruit-drier, the Shen A, having uw' cold-air apertures a, iu combination with the furnace B, the return-fines C, connected therewith, and theplates c2, whereby the curved passages a are formed about the return-flues for admitting the outer air to the interior of' the shell, substantiall y as herein described.
2. In a fruit-drier, the combination, .with the shell A, having a diaphragm dividing the said shell into a ilue and heating-chamber, re spectively, of a furnace, B, the return-fines separately connected with the rear of the heat- 'ing-chamber, passages a, formed in the sides of the shell, and the curved plates a2, forming the passage a around the returnliue for admitting the outer air tothe heatingchamber, substantially as herein described.
In wit-ness whereof we have hereunto set our hands.
