Toallwhomz'tma .concer/m:
B e it known t at we, ELWOOD B. .Axims and HERMANN BOGATY, citizens of the United States, residing in the city and county of Philadelphia, Pennsylvania, have invented certain Improvements in Rotary Driers, of which the following is a specilication.
One object of our invention is to construct a drier in which the articles to be dried are located onl a rotarycarrier within a chamberwhil'e heated air is circulated in the chamber.
A further object of' the invention is to` construct a drier so that the articles can be -fed automatically tothe rotating carrier, and, when dried, canbe discharged automatically therefrom'.
The invention also relates to details of construction', which will be fully described hereinafter. l
In the accompanying drawings: A
Fig. 1 is a longitudinal sectional view of our improved drier;
' 25 Fig. 2 is a plan view;
Fig. 3 is a transverse sectional .view; and
Fig. 4 is a perspective view of a berry basket.
The present machine is so designed that it V can be used in connection with a berry basket forming machine. The baskets come from the ,forming machine iii-a damp condition and must be thoroughly dried before they can be acked for shipment. It will be' un- 36 derstoo however, that the machine can be used for drying other articles withoutdeparting from the main features of the invention.
1 is the casing'of the drier. This casing encloses a drying chamber in which is a rol-tary carrier 2 supported by wheels 2a. This carrier consists of two heads 3 connected by an annular series of L-shaped strips 4, form.
ing pockets 5 for the articles 'to be dried.
The strips are separated so that air can circulate around the articles, which, inv the present instance, .are 1berry baskets made of wood bent into shape and fastened. These baskets are nested and each pocket is shaped '50 to receive a series of baskets extending the h of the carrier. A cylindrical screen 4a'is located within the carrier and forms the bottoms of the pockets 5. This screen is secured to the full lengt heads 3 and the strips Li--making alight,
yet substantial construction. 0n each head 3 of the carrier are gear teeth, which meshI with the teeth of the gear wheels 6 on a shaft 7 that extends through v I i one end of the casing. 8 is a worm wheel on the shaft 7 which meshes with a worm' 9 on a driving shaft 10, which is synchronized with the basket making machine.
The shaped strips and screen retain the baskets in the ockets while they are on the upper half of t e carrier, and, as the pockets are open, a series of curved slats 11 are locateddirectly under the lower half of the carrier so that, as the lbaskets pass the oenter, they rest upon the slats which hold them ,in place while they are being carried to the delivery point As the slats are discony tinued at this point, the nested baskets are released and slide down the incline 12 onto a belt conveyer 13, or other suitable receptacle.
In the present instance, the baskets are fed intothe drier automatically.
14 is a belt conveyer, which receives the nested baskets in a damp condition from a basket making machine. Under the conveyer is al plate 15, which extends into the drying chamber close .to the carrier. 16 is a pusher actuated from a timed shaft 17 through levers 18 and connecting rods 19 so that a series of nested baskets will be in position to be projected into a pocket of the drier when the pockety is in proper alignment. v
Y There is a considerable space between the feeding mechanismV and the discharge mechanism, as shown in Fig. 3. This space is closed by a curved plate 20.
21 are the heating coils located within the carrier 2. These coils are supported by I- beams 22 extending longitudinally withinv the drier casing.
`23 are the circulating fans. These fans are located in openings 24 in stationary casings 34 Within each end of the rotary carrier and are mounted eccentrically in reslpect to the carrier so as to allow room for the coil supporting beams 22. Each fan is mounted on a shaft 25 extending to the outside of the casing and, provided with a belt wheel. When the fans are in motion, the air circulates in the direction of the arrows, Fig. 1.
bent into shape when in a damp condition.,`
The baskets are so designed that they can be nestedand one roW after another is introduced automatically into the pockets of' the carrier, and, as the carrier slowly rotates, the heated air in circulation dries the baskets so that, when they reach the delivery point w, they are in condition to be packed and shipped.
lWhile the Wheels 2a are shown as supporting the carrier, it may be supported by bearings mounted on the beams 22, or it may be otherwise supported without departing from the main features of the invention.
We claim:
1. The comhination in a drier, of a casing; a hollow rotary carrier arranged to r'otate around a horizontal axis, said carrier having longitudinal pockets in its periphery to receive the articles to be dried; a series v of heating pipes located Within the rotary carrier but independent thereof; and means for circulating air Within the casing and around the articles mounted on the carrier and around the heating pipes.
. located Within the chamber, said carrier having two heads and L-shaped connecting strips forming pockets for the articles to be dried; means for circulating air in the drying chamber; and means for heating the air.
3. The combination in a drier, of a casing enclosing a drying chamber; a rotating carrier located within the chamber and having a series of' pockets for the articles to be dried; a stationary casing at each end of the carrier, each casing having a fan opening; a circulating fan located in each fan meente opening; means for operati the fans; and a heating coil supported vvit in the carrier.
Il. The combination in a drier, of a casing enclosing a drying chamber; a cylindrical carrier supported Within the drying chamber having longitudinal pockets for the articles to be dried; an endless con- Veyer at one side of the drier; means for automatically transferring the articles to be dried from the conveyer to the pockets ot the carrier; an endless' conveyer under the first mentioned conveyer arranged to receive the articles as they are discharged from the carrier; and means for circulating heated air in the drying chamber.
5. The combination in a drier, of a casing enclosing a drying chamber; a cy-v lindrical carrier 'located Within the drying chamber, said carrier having a head at each end and strips extending from one head to the other so spaced as to form pockets for the articles to be dried; beams extending longitudinally through the carrier; heating coils mounted on the beams Within the carrier; and a circulating fan at each end ofthe carrier mounted eccentrically in respect thereto. Y
6. The combination in a drier, of a casing enclosing a drying chamber and havinga feed and a delivery opening; a cylindrical carrier located in the drying chamber, said carrier having a head at each end connected by a cylindrical screen and longitudinal strips, said strips being spaced apart to form pockets for the material to be dried; means for supporting the carrier; curved slatsflocated directly under the carrier for supporting the articles as they are fed towards the 30 discharge point; and means for circulating heated air in the drying chamber.
