UNITED STATES PATENT OFFIOE.
DOUGLAS GORDON, OF WORCESTER,
MASSACHUSETTS, ASSIGN OR TO MARCUS MASON & COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
COFFEE-DRIER.
To LZ wir/0771, t may concern:
Be it known that I, DOUGLAS GORDON, a subject of the King of Great Britain, and a resident of Worcester, county of Worcester, State of Massachusetts, have invented certain new and useful Improvements in Coffee- Driers, Of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
My invention relates to improvements in coffee-driers of the type employing two perforated concentric cylinders adapted to receive a charge in the annular space between them and provided with means for admitting air to the interior of the inner cylinder.
My present invention resides in a novel means for admitting and distributing air within the inner cylinder; and it consists in means having a connection with a source of air-supply at one end only of the inner cylinder, said means admitting a part only of the air thus received at such end of the cylinder, and means for carrying the remainder of the air thus admitted to the opposite end of the cylinder, to be discharged into the said cylinder at that end thereof.
In order that my invention may be fully understood, I will describe in detail7 with reference to the accompanying drawings illustrating same, an apparatus embodying my invention and will then point out the novel features in the claim.
In the drawings, Figure l is a view in central vertical longitudinal section through a drier embodying my invention, and Fig. 2 is a detail view in transverse section through a portion thereof upon the plane of the line 2 2 of Fig. 1.
The drier comprises an outer perforated cylinder 5, an inner perforated cylinder 6, closed end heads 7, and trunnions 9 and 10, securedto said end heads, supporting the said drier in bearings 13 upon standards 14. The charge to be dried, which may be different kinds of grains, berries, and the like,and particularly coffee-berries, is arranged to be contained in the annular space between the two cylinders 5 and 6, the space within the cylinder 6 being unoccupied, so far as the berries are concerned. I make no claim,
Specication of Letters Patent.

however, to this particular form of drier per se, the essence of the present invention being the means, in combination therewith, for introducing air to the space within the cylinder 6, from which itv may bedischarged through the perforations in the said cylinder 6 to the annular charging space between the two cyl inders 5 and 6 and thence outward through the perforations in the cylinder 5. This is as follows:
The trunnions 9 and 10 are made hollow, as shown, one of the trunnions 9 being open clear through and arranged to beconnected with a source of air-supply, (under pressure,) the other trunnion being closed by means of a cap 15, the inner portion of which acts as a deflector. Arranged centrally within the cylinder 6 and extending with its ends into bothv of the said trunnions is a central openended tube 1l, the outer diameter of said tube being less than the inner diameter of the said trunnions. The tube is connected with the said trunnions by means of spiders l2, said spiders leaving free passage for the currents of air through the annular passage between the said tube and trunnions..
Currents of air entering the trunnion 9 will be divided, a part thereof passing on through the central tube 1l and a part entering the cylinder 6 at the end at which the said trunnion 9 is'arranged. That part of the currents which passes on through the tube 1l will enter the trunnion 10 and will be deflected by means of the deiiector 15 to the annular space around the said tube, to be discharged into the cylinder 6 at the end thereof, at which is the trunnion 10. By
this means the air will be evenly distributed within the inner cylinder 6, and hence evenly distributed throughout the apparatus. The currents of air will be divided and will be admitted half and half to opposite ends of the drier in a very simple manner, even though the connection to the air-supply is at one end only thereof.
What I claim is* A drier comprising two concentric perforated cylinders arranged one within the other, opposite end heads therefor, hollow trunnions projecting from said heads, one of IOO seid trunnions arranged to be Connected of said trunnions, whereby a passage is left Wlth a supply of an under pressure, and the between the trunnons and the tube for arother of said trunnlons closed to the eXterlor currents, substantmlly as set forth.
and provided nterorly with a defletor, and DOUGLAS GORDON. a central tube opening at both ends into the t NTtnesses: said trunnions, the outer diameter of said T. LEVERETT NELSON,
tube being smaller than the inner diameter JANET GORDON.
