BERNARD DUWEL, CHARLES DUIVEL, AND FREDERICK DUVVEL, OF CINCINNATI, OHIO.
TOBACCO-DRIER.
SPECIFICATION forming part of Letters Patent No. 770,742, dated September 27, 1904.
Application filed May 22, 1902. $erialNo.108,476. (N m d l.)
To (LZZ whom, it mlmy concern:
Be it known that we, BERNARD DUWEL,
()HARLES DUWEL, and FREDERICK DUwEL,citi- Zens of the United States of America, and residents of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Tobacco-Driers, of which the following is a specification.
The object of our invention is a means for drying tobacco after it has been cased in which there is no probability of scorching the tobacco nor of injuring its flavor nor of allowingit to become twisted together and which is rapid and thorough in operation.
The means by which we attained this object is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a drier embodying our invention, the belt for rotating the drum being shown broken off. Fig. 2 is a longitudinal sectional view of the drum. Fig. 3 is a front elevation of the drum. Fig. 4 is detail interior elevation of the end of the conduit which conveys the currents of heated air into the front end of the drum. Fig. 5 is a transverse sectional view, upon an enlarged scale, taken upon line m m of Fig. 1.
Referring to the parts, drum A consists of cylindrical sections a, secured to one another at their ends. The rear end of the drum is closed by a head a, near which is a dischargeopening (6 upon one side of the drum. The drum has three circular annular flanges a which engage rollers b journaled in brackets Z2 mounted on I-beams B. Drum A has secured to it an external ring a, which re ceives the actuating-belt C, which imparts a continuous rotation to the drum. The front end of the drum is closed by a cap D, which is supported upon a standard (Z, which is secured to the floor. Cap D is stationary, and the cylinder rotates within its flange d. Cap D has a feed-opening (Z through which the tobacco is fed into the drum, whichis given a slight inclination downward toward the rear, so that the tobacco is fed forward to the discharge-opening a Sections (6 have secured upon their interior longitudinal radial plates a a. l/Vithin each section we place three of these plates at one hundred and twenty degrees apart. The plates 60' upon one section are staggered with plates a of the preceding section-that is, are at sixty degrees from them. The object of this construction is to prevent the tobacco becoming twisted or bunched, as it is inclined to do when the plates upon the adjacent sections are placed in alinement with each other. The eflfect of staggering the plates is to break up any twists.
Leading into the upper part of cap D is a pipe E, which upon its inner end is closed by a plate a, which has a longitudinal pipe 6 leading for ashort distance straight into the drum and arranged below pipe E five outwardly and downwardly directed short pipes 6 Through pipe E are directed currents of hot dry air. Pipe 0 directs part of this current of heated airstraight through the cylinder, while pipe 6 directs part of it against the innor sides of the drum.
The tobacco, after it has been cased or flavored, is fed into drum A through opening 6Z2. Drum A being surrounded by the atmosphere does not become heated up to a degree such as to scorch the tobacco which comes in contact with it. Plates a keep the tobacco well separated, so that the heated air comes freely into contact therewith. We have found that tobacco so treated retains its flavor in a higher degree than that treated by processes wherein the drum is heated and that the quantity of tobacco which may be dried in a drum of a given size within a certain time is greater than in the processes aforementioned.
What we claim is 1. In a tobacco-drier the combination of a revolving drum, an opening for feeding tobacco therein, a pipe leading into one end of the drum for conveying heated air, and a plate secured upon the inner end of the pipe carrying a main longitudinal pipe and smaller radiating-pipes for spreading and directing the heated air as it passes through the drum, substantially as shown and described.
2. In a tobacco-drier the combination of a drum made up of cylindrical sections, radiating-plates secured upon the interior of the through the drum, substantially as shown and I0 described.
