WILLIAM HULL AND CHARLES W. HAMMOND OF BALTIMORE,
MARYLAND.
Letters Patent No. 95,351, dated September 28, 1869.
GRAIN-DRIER.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom t't may concern Be it known that we, WILLIAM Hum. and Crmnnns W. HAMMOND, of the city and county of Baltimore, and State of Maryland, have invented a new and improved Grain-Sweater, Dryer, and Cleaner; and we do hereby declare that the following is a full, clear, and exact description of the construct-ion and operation of the same, reference being bad to the accompanying drawings, making apart of this specification, in which Figure 1. is a vertical cross-section through line 3 y of fig. 2. I 1
Figure 2 is a longitudinal vertical section through line at x of fig. 1.
This invention relates to'ihat class of machines for cleaning grain, 81a, in which a hollow-rotating cylinder is employed, provided with oblique or worm-- flanges, partitions, or deflectors for moving the grain longitudinally with the cylinder, as the latter rotates; and
Our improvement consists in the employment, in connection with such cylinder, of another surrounding cylinder or cylinders, having oblique deflectors, inclined in the opposite direction to those of the inner cylinder, and so constructed, thatwhelrthe grain has been moved the whole length of the inner cylinder, it will escape therefrom, and fall into thenext outer one, and therein travel back to the point where it was first introduced into the machine, and so on, from cylinder to cylinder, till it is perfectly cleaned and dried.
In connection with this arrangement of cylinders and oblique deflectors, we employ a peculiar arrangement of sieves or screens, to screen oh the dust, 860., from the grain, as it tr: vels along from end to end of And outside of all the working-cylinders above referred to, we place a hollow shell, or double-wall cylinder or jacket, through which hot air, steam, or other heating-agent is passed, in order to dry and sweat the grain subjected to the cleaning and polishing-operation within the enclosed cylinders.
In the drawings- F is the supporting-frame, and S is the workingshaft, which carries and rotates the several cylinders at once. v
A is the inner cylinder, receiving the grain from a hopper at its left-hand end, fig. 2, where it is open at its centre, and, when rotated, conveying the'grain along to its opposite end, by means "of oblique worm,
or screwshaped deflectors, a a a, forming between them a spiral passage, along which thegrain travels.
lVhen the grain arrives at the right-hand (fig. 2) end of this cylinder, it falls out, and is caught in an enclosihg-cylinder, B, and by this cylinder conveyed back to the left-hand end of the machine, by means of spiral or oblique deflectors, b b 7), arranged in a direction opposite to that of the deflectors a a a.
As it travels back to its starting-point between the deflectors b I), it is sieved or screened, by means of wire sieves or foraminated plates, 0 c a, forming the floor on which it moves, the dirt dropping through the sieves into the space e, and travelling along to the end of the cylinder directly under the grain.
The grain is discharged at G into a suitable receptacle, and the dirt at E into another.
Around these cylinders is the steam or hot-air space G, into which the steam, air, or other hcasing agont is introduced at any suitable point, and from which also it may be removed wherever most expedient.
If steam is employed, suitable drip-pipes or cocks may be arranged along its under edge;
The heating-jacket or cylinder G is not rotatory, being supported on its own frame.
The jacket may be. so constructed that either steam or hot air may be employed, at pleasure. Suitable doors may be provided for the purpose of opening the cylinders, to clean them, 850. They may, for this purpose, be constructed in longitudinal segments of any suitable size. 1
It is evident that we need not be restricted to two conveying-cylinders, carrying the grain once back and forth, as shown in the drawing, but any convenient and practicable number might be used, the inner one always emptying at one end into that next enclosing it By the process herein described, the grain is not only cleaned and polished, but, at the same time, it is thoroughly sweated and dried, so that it will keep for almost any length'of time.
H. ving thus described our invention,
What we claim as new, and desire to secure by I Letters Patent, is-
The screen 0, combined with the enclosing-cylinder B, dirt-space e, and spiral flanges 11, substantially as and for the purpose set forth.
