Application filed January 131906. Serial No. 295,911."
To all whom .it may concern: j
Be 1t known that I, IFRANK M.l SCHAEFFER,
a citizen of the lUnited States of America, residing at Indianapolis, in the Vcounty of Ma- 1ng san( and gravel.
My invention aimsto provide positive and reliable means for speedily and eifectually drying sand and gravel, and in this connection- I have devised a novel form of apparatus into which the sand or gravel is fed,
quickly dried, and delivered in a dried state to a point adjacent to the apparatus.
To this end the apparatus involves two re volving drums or cylinders into which the sand or gravel is fed. The drums or cylinders are subjected to heat from a fiame which passes into one of the drums or cylinders, causing the sand or gravel to become thoroughly heated and dried before its delivery from the apparatus. In order that the sand or gravel may be thoroughly dried, I have devised novel means for revolving the drums and thoroughly mixing and agitating the sand or gravel while being subjected to the heat of the flameentering one of the drums or cylinders. The a itating or mixing means also serves functiona ly for propelling or feeding the sand or gravel through the apparatus.
The' detail construction of my improved "sand and gravel drier will be hereinafter more fully described and then specifically pointed out in the claims, and, referring to the drawings accompanying this application, like numerals of reference vdesignate corresponding parts throughout the several views, in which- Figure 1 is a longitudinal sectional view of my improved apparatus. Fig. 2 is a plan Fig. 3 is a front view of the apparatus. Fig. 4 is a rear end view taken on the line of Fig. 1. Fig. 5 is a cross-sectional view taken on the line y y of Fig. 1 looking in the direction of the arrow of said gure. Fig.
'tion with the apparatus view of a roller associated with said pinion. f The apparatus illustrated the accompa-v plasterers, and likearti'sans for dry- I,
6 is a detail view lof a pinion used in connecnying drawings is adapted to be constructed in the vicinity of the work in connection with which sand or gravel is used, the sand or gravel being fed direct totheapparatus from the river-bed or ground from which it is obtained, in the majority of instances the sand and gravel being obtained from a river-bed and fed to the apparatus in its wet and damp state. In constructing the 'apparatus I` have' aimed to provide as reliable a structure as possible in order to reduce the labor used in -connection with such an apparatus, and the few parts used in connection with the apparatus permits of it being easily and quicklyy disassembled for shipment when it is to be used upon another site to drysand or gravel. In practice -I construct a housing or comartment 1, which consists of side walls 2 2, a
e wall or bridge 3, and a drum or cylinder supporting plate 4. The compartment 1 is closed by a top plate 5, having an oval iianged opening 6 formed therein, over which` is mounted a stack or chimney 7.
The drum .or cylinder supporting plate 4 is substantially rectangular in elevation and is preferably made in two parts 8 and 9, each part being provided with a semicylindrical opening 10, formed by Hanging the plate 4, asf Aclearly illustrated in Figs. 1 and 5 of the.
drawings. The semicylindrical opening of the plate 4 forms a bearing for an outer 'drum or cylinder 11, having its rear end closed by an end'plate 12. The drum or cylinder 11r adjacent to the plate 4 has its periphery prof vided with a channel-track 14, in which engages rollers 15 15a, journaled upon studs 16 v16, carried by the plate 4, said rollers being arranged at each side of the plate 4, thereby formingia bearing upon which the drum or cylinder may revolve.
Adjacent to the rear end of the drum or cylinder I provide a peripheral rack 17 ,and meshing with said rack is a. pinion 18, which is mounted upon a shaft 19, journaled in a bearing or housing 20. The shaft 19 is also journaled'in a bearing or housing 21, and upon said shaft are mounted belt and pulley wheels 22 22, whereby the shaft 19 may be rotated to' revolve the drurnlor cylinder 11.
The pinion 18 is preferably'arranged in Fig. 7 is a detaill ICO s'aaoaa means to revolubly support said drums, and means engaging said peripheral rack to revolvesaid drums, substantially as described.
'2. In a drying apparatus, the combination with a furnace, of a compartmentarranged at the rear end of said furnace, drums extending into said comv artment, spirally-arranged conveyers carrie by the inner walls of said compartment, a chute mounted in said compartment and extending into one of said drums,l means to revolubly support said drums, and means to revolve said drums, substantially as described.
3. In a drying apparatus, the combination with a furnacefof a compartment arranged at the rear of said furnace and communicating therewith, said compartment having an outlet, drums revolubly mounted adjacent to said compartment and protruding therein, a chute mounted in said compartment and eX- tending into one of said drums, spirally-arranged conveyers mounted in said drums, and means to revolve'said drums, substantially as described.
4. In a drying apparatus, a drum-supporting plate madein two sections secured t0- gether, rollers carried by one of said sections, an outer drum revolubly mounted in said supporting-plate and having a circular track rest-ing on said rollers, a plate closing one end of said drum, a spiral conveyer carried by the inner wall of the drum and arranged to carry material toward the open end of the drum, an inner drum mounted within the outer drum open at both ends, said inner drum being rigidly connected to-the outer drum andA of considerably less diameter than the outer drum to form a space between the two drums, a spiral conveyer carried by the inner drum and arranged oppositely to that .of the outer drum, and means for revolving said drums.
5. In a drying apparatus, an inner and an outer drum, the outer drum closed at one end and open at the other end, and the inner drum open at both ends and having one end extending beyond the open end of the outer drum, a spiral conveyer carried by the inner drum arranged to convey material toward the closed end of the outer drum, a spiral conveyer carried by the outer drum arranged to convey` material toward the open end of said outer drum, and a hopper having a circular discharge end receiving the extending end of the inner drum which revolves thereon.
6. In a drying a paratus, two drums arranged one within t e other, and rigidly connected to be revolved in unison, spiral conveyers carried by the drums and arranged in opposite directions, a pair of rollers arranged near one end ofthe drums on which the outer drum revolves, and a roller and a pinion arranged near the other end of the drums Von which the outer drum revolves, a rack carried by the outer drum meshin with said pinion,
and means for rotating sai the drums.
7.' In a drying apparatus, an inner and an outer drum connected together to revolve in unison, the inner drum being spaced away pinion to revolve from the outer drum and having its receivingend projecting beyond the adjacentI end .of the outer drum, a plate closing the one end Yof the outer drum, a spiral conveyer within the inner drum arranged to convey material toward the closed end of the .outer drum, and a reversely-arranged spiral conveyer within the outer drum to convey the material to the' open end of said outerdrum.-
8. In a drying apparatus, a feeding chute or hopper terminating in an open cylindrical discharge end, and a furnace having an outlet-opening in alinement with said discharge end, combined with an inner drum open at both ends with one end received on the discharge end of the chute or hopper, an outer drum closed at one end and rigidly connected to the inner drum, conveyers 'in said drums, and means for rotating the drums; In testimony whereof I aHx my signature in the presence of two witnesses.
