SPECIFICATION forming part of Letters Patent No. 234,412, dated November 16, 1880.
Application filed June 17, 1880. (No model.)
To all whom t may concern Be it known that we, GEORGE P. LEE and LEVERETT J. LEE, residents of the town of Greece, Monroe coun ty, New York, havejointly invented certain Improvements inFruit-Driers,
of which the following is a specification, reference being had to the annexed drawings, in which- Figure 1 is a side elevation, partly in section, of our improved fruit-drier. Fig. 2 is a horizontal section ou the line x x, Fig. l, showing the parts below that line. Fig. 3 is a side elevation ofthe adjustable boxes which carry the ends ofthe rollers. Fig. at is a horizontal section of the same on the line jl/ y, Fig. 3. Fig. 5 is a side view ofthe bracket which supports the roller c.
Our invention relates to an improved fruitdrier, in which the fruit is dried while passing through a drying-chamber on a series of endless wire-cloth belts placed one above the other, and arranged to deliver the fruit from one to the other, each lower belt having a slower motion imparted to it than that given to the one next above it.
Our invention also consists in the combination, with the series of endless belts arranged as just mentioned, of a series of steam-heating pipes arranged between the belts and having a steam-circulation from above downward, for the purpose of subjecting the greenest fruit to the hotteststeani; and it also consists in the mechanical construction and arrangement of the apparatus, as hereinafter more fully pointed out.
Our improved fruit-drier is represented in the accompanying` drawings, in which A A is the frame of the machine; B, the siding; C, the top or roof; D,the belts, and E the steampipes.
In the construction of our improved fruitdrier we form an inclosure or drying-room, of a size adapted to the quantity of fruit to be operated upon, by constructing a suitable frame-work, A, and attaching sides, ends, and roof thereto, as represented in the accompanying drawings.
Within the drying-chamber and at each end thereof are placed a series of horizontal rollers, a a a b b b, over which pass the endless wirecloth belts D D. The ends of the rollers are supported in suitable boxes attached to the siding or frame ofthe machine.
Motion is transmitted to the series of rollers b b b by means of a chain, d, running over pulleys e e e on the roller-journals, in such manner that the upper parts of the belts D D travel in reverse directions, as represented by the arrows in Fig. 1, so that the fruit'to be dried, being placed on the upper belt between the side of the machine and the roller c', is carried by it to the opposite end of the drying-chamber and there delivered to the next lower belt, by which it is brought back to the righthaud end of the machine, to be there delivered to the next succeeding belt, and so on from belt to belt until it is finally discharged from the machine, fully dried, by the lowest belt, at G, Fig. 1.
Suitable chutes or guide-boardsfff, placed across the machine below the ends of the belts in the proper positions, insure the delivery of the fruit from one belt to the next lower belt.
The rollers are so placed that each belt is somewhat shorter than the next lower belt at one end or the other, so as to effect the delivery of the fruit from belt Yto belt as it passes downward through the machine. The motion of each belt is slightly slower than that ofthe next Lipper belt, 'the pinions on the rollers b b b being made larger from above downward, so that the lower belt travels two or three times as fast as the upper ones.
A chain, d, running around the pinions, serves to revolve each alternate shaft b in the opposite direction to that in which its neighbor turns, so as to .give motion in the proper directions to the belts D D D. The chain is carried around corner pulleys, g h, anda crank, t, is attached to the shaft of one of the rollers b b b, by which the machine is operated.
Itis evident that the proper relative motions can be given to the belts D D D by means of a train of gears with intermediates between the shafts where the pinions are small; but we prefer the chain, as herein shown.
The journals of the rollers b b b are supported by boxes secured to an upright, j, on the side of the machine and formiu g part of the frame thereof.
The journals of the rollers c a a revolve in boxes m, Figs. 2 and 4, which are made ad- IOO just-able lengthwise of the belts D D, for the purpose of regulating their tension.
An opening, 19, Fig.'4, is made through the side B of the machine for the purpose of permitting the removal ot' the roller, and this opening is closed by the box m, which is provided with a ilange, l, ot' sulcient width to cover the opening p in whatever position the box and roller may be placed.
The flange l is provided with horizontal slots a a, Fig. 3, through which pass bolts 0 o, by which the box is secured to the siding. rlhese slots permit the horizontal adjustment ofthe box m and rollers, so that the tension of the belt D may be regulated thereby. Each ol" the series ol' rollers a a is provided with these adjustable boxes at each end thereof.
The roller a is made adjustable by means ot' a sliding box, a', attached to the bracket s by means ofthe bolt o', Fig. 5.
The position ol' the box m when moved to the right as t'ar as the slots n yn will permit is shown in dotted lilies m l', Figs. 3 and 4.
rFhejournals of the roller a", the function ot' which is to support the belt D and to close the opening into the machine between the upper and lower portions of that belt, so that aircannot enter or escape through it, need not be made adjustable.
The boxes ot' the roller a/f, which carries the right-hand end ofthe lower belt, and also operates to prevent thc passage ot' air, may be made adjustable by slightly changing the t'orm of the flange l.
The openings through the side of the machine above the upper and lower belts are closed by a cloth or curtain, t t, attached to the side and hanging down over the fruit, as it passes in and out of the machine, so as to prevent as much as possible the escape or entra-nce of air at these points.
The series of steamp1pes E E are supported by iron rods a u u, Fig. l, passing' across the lnachine. rlhe pipes are connected at each end with suitable distributing-pipes t; a, by which steam is introduced into them. Steam is introduced into the upper row of pipes by means of the suppl y-pipe te, and discharged from the lowest row through the pipe z, the object being to subject the fruit, when lirst introduced into the machine, to the greatest degree of heat. Steam passes from each upper row of pipes to the next lower row through pipes p 19'.
Provision is made for the introduction of air into the lower part of the drying-chamber by sliding doors 1" r at the lower part ofthe machine.
In Fig. 2 the wire-cloth belts are broken away, so as to show the steam-heating pipes. rlhe ends of the wire-cloth belts may be connected together by soldering, sewing with wire, or by hooks.
A valve, s', for regulating' the escape ot' air from the drying-chamber, may be placed in the top thereof.
Wie are aware that steam-heating pipes have been previously used to heat a volume of air on its introduction into a drying-chamber con taining a series of horizontal belts, and such arrangement we do not claim, as it is essential .to the proper o})eration of our invention for the purpose of drying' fruit that the steamheating pipes should be located between the fruit-carrying belts, and that the steam should be introduced into s-aid pipes at their upper ends, so that the greenest fruit on the uppermost belts shall be subjected to the greatest degree ot' heat.
7e do not claim anything shown or deY scribed in the patent ot' Miller, No. 44,260, or of Vilson and Catlin. No. 215,191.
XVe claim- 1. In combination witha series of steamheating pipes, E E E, the endless wire-cloth belts D D D, arranged to deliver the fruit from one to the other, and having differential motions imparted to them by means ot' pinions c c c, ot' differing sizes, and chain d, so that the lower belts move slower than those above them, substantially as described.
2. The combination ot' the series ot' belts D D D, rollers a a a b b b, roller af, located outside ot' the machine, and rollers a 16 in the openings through which the upper and lower belts-pass in the side of the machine, substantially as described.
In a fruit-drying chamber, a series of endless wire-cloth belts, D D l), passing over rollers at either end thereof', arranged to deliver the fruit from one belt to the next lower, and having differential motions imparted to them by pinions c e c and chain d, substantially as described.
