.5 ren and State of Pennsylvania, have iiivented a new and' useful Improvement in Fone-Black iirnaces, of which the following is -a specifica tion.

ing or reclaiming bone, fullers earth, or other filtering material which has been used in oil relinerics or other places for-filtering purposes.' A

`Heretofore suoli furnaces have ordinarily been constiiictcd'in the greater part of iron or steel. which r'endcred them liahle to burn out'quickly 'and made therii expensive'to keep in repair an'd diieult to preserve in good running order.

The object of my present invention -is to obviateA such ditculties and' to providc'a furnace for `the purpose mentioned which shall be inexpensive in construction, durable, easy to keep in repair, :md extremely etfi-` 'cent iii-operation.

At. one side of the furnace near the top tthereof .and extending across the j same -is a. hopper 6 for supplying 'the burning-shafts 2 with the bone or other material to be burned,-cleanedl and purified. The bottom of this hopper is provided with a M. invention relates to furnaces for burn- 13 adapted to be o rate vcrticalxsectioii ou the'liiie" fixed floor-plate 7 having hole's or openin 6 therein, and also with an adjustablesli ing plate 9 provided with holes oropenings The slide. 9 isroperated to'bring the holes 10 and .8-more or less in register with 60 y each other and thus vary the size ofthe feed openings leading toA the shafts 2 or-entirely cutoli the saine, b means of a -rack 11on the end of the, sli in plate which meshes with a pinion V12 on t e u rend of a rod 65 y-a handfwheel 14 on its lower en 15 are rails by wliich cars carryin bone or other`- material to be burn are brought over' the hopper 6. 70

Leading froni't-he openin 8 in the floorplate 7, are incliiies 16, which .feed the ma.- terial into the shafts 2. Each of the shafts 2 is provided with a series of 'baille projec'- tions 17, provided with do '.ynwardly-m- 75 clined upper'surfaces andextending about midway across the shaft' alternately. from opposite sides thereof for. the pur-pose of ivingto the bone or other matri urncd a zig-z agor tortuous course down '80 the shaft fromgrits'lentrance over the incline 16 to its'exit at the discharge outlet 4r.
