Specification of Letters Patent.
'Patented Feb. 18,1908.
/ticularly to an apparatus of this character in which a plurality of drying drums are employed, the material to be dried and the dry,- ing medium being passed through said drums in opposite directions. Said invention consists of means hereinafter fully described and particularly set forth in the claims.
The annexed drawings and the following description set forth in detail certainv means embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.
In said annexed drawings Figure 1 represents a side elevation of my invention; Fig. 2 represents a right hand end elevation of the same; and Fig. 3 represents a transverse vertical section of the two drums and connected parts forming important elements of my invention, said section being on an enlar ed scale.
n the' construction of drier which I have shown in the accom anying drawings and shall now describe, haveemployed two drumsfone disposed Withinv the other, both of which are inclined, the inclination being by arrows in dotted lines.
in opposite directions and the material'to be dried, such as'coal, rock, etc.. and thev drying medium being passed through said drums in opposite directions, thedirection of movement ofthe heating medium, which in this case is hot .air, being` designated by arrows in full lines and the direction of movement of the material to be dried being indicated In order most sim ly lto'seoure the relative arrangement of drums just described, I provide the structure shown in the'several iigures above described, see particularly Fig. 1. This structure comprises an outer cylindrical drum A, mounted so as to be inclined in one direction, and an auxiliary drum B of conical or substantiallyconical form mounted within said outer drum, and in axial alinement therewith, the effect of its conical form being to cause its lower wall to incline in a direction opposite to the direction of inclination of saidv outer cylindrical drum. It will thus be seen that I provide an outer drum that is in effect inclined, Fig. 1, from left to right, and an inner drum inclined from right to left. Said outer drum A has a door a and is rotated by meansof a girth gear .D that meshes with the pinion d, the latter being rotated through connected means from the pulley E, all asis shown in Fig. 1. Drum A is rotatably supported by the riding rings C C which bear upon the rollers c c, respectively. v
A furnace F is provided having the rate surface f and the fuel and ash doors f2,
respectively. The feed spout for the material to be dried is shown at H, the same terminating within a chamber L contained within which is one end of a screw conveyer H or equivalent means terminating at its other end within 'the inner drum B, whereby the material is fed into said drum and then during the rotation of the latter is gradually fed downwardly through the-same to the left as indicated by the dotted arrow. The right hand end of the drum B is closed so that the heating medium from the furnace F can obtain no access to said drum at this end but passes around the same and intermediately of the two drums A and B, entering the inner drumB at its left end, as plainly indicated by the fullarrow, leaving said drum B at its right hand end,. being drawn therethrough by means of the fan J. A suitable foundation K is provided for the drier, and at the ri ht hand end of the apparatus is disclosed a ousin L for-the furnace F, the chamber h and ot er connected elements. The material which is being dried is discharged from the left hand end of the inner drum B into the outer drum A throughwhich it radually,
progresses during the rotation of t e latter, eing discharged from the same from the end a, Fig'. 1, into trough a3 containing `a screwy or equivalent conveyer a4 by means ofwhich it is removed from said trough, .as willl be readily understood. y
Disposed adjacentlyto each ofthe drums A, B is a series of annular rings or bands A B',Y respectively, each drum and its related; rin s being connected together by i 3.y In a drier, the combination of a rotary means of ongitudinally disposed angle irons drum; annular rings disposed interiorly of forming elevators for the drying material, as 1 the latter;v and angle irons adapted to lift willl be more fully described hereinafter, said l the material, said angle irons being connected angle irons being connected to the rings` and to said rings and normally abutting said normally abutting the inner peripheries of drum, so that relative movement of the latthe respective drums7 the same, however,
' not being rigidly fastened to said drums so that contraction and expansion of the conter and said ringsris permitted during their contraction and expansion.
4. In a drier, the combination of a rotary nected rings and drums is permitted without 1 drum; means disposed adjacently to the inundue strain.
The angle irons adjacent to ner periphery of said drum and adapted to the drum A are designated by the reference elevate the material; and a plurality of ancharacter a, Fig. 3, and those adjacent to the inner drum B by the reference character b,
and it will be noted that as said drums are rotated as indicated by the arrows, Fig. 3, said angle ironswill convey the material from the lower portions of the respective drums -to the upper portions thereof where the mathe bottom of said drum contact with the eX- teriorsurface of the drum B and thus receive an additional drying.
The extended annular space lying between the inner surface of the outer drum, and the outer surface of the inner drum is furthermore sub-divided by longitudinally disposed partitions A2 into a plurality of segmental compartments, see Fig. 3. By this construction heaping of the material being dried in the lower portion of the outer drum is prevented since such material is divided up be tween the several compartments in question so as to be in effect passed throu h a plurality of individual drums in each of w iich the relatlvely smaller proportion of such material 1s mdependently subjected to the action above described.
Other modes of applying the principle of my invention 'may e employed instead of the one explained, change being made as regards the means herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.
I therefore particularly point out and distinctly claim as my invention nular rings to which said elevating means are attached. .i

In a drier, the combination of two rotary drums inclined in opposite directions; elevators disposed within each of said drums; means secured to said drums respectively v and supporting said elevators; and longitudinally disposed partitions dividing the space intermediateA of said two drums into com' partments.
6. In a drier, the combination of two rotary drums inclined in opposite directions and disposed one within the other 5 elevators disposed adj acently to the inner periphery of each of said drums; means secured to said drums respectively and supporting said elevators; and longitudinally disposed partitions dividing the space intermediate of said two drums into compartments.

Ina drier, the combination of two rotary drums inclined in opposite directions and disposed one within the other angle irons longitudinally disposed adjacently to the inner periphery of each of said drums.; a plurality of annular rings contained within each of said drums, said angle irons being attached to said rings, and a plurality of longitudinally disposed partitions dividing the annular space intermediate of said two drums into segmental compartments.
