Y In the drawings, A is the grate, which is conicalin form,v the apex of the Acone being out oi to make an opening for the Split pipe n, ct', which guides the grate inits upandfdown movement` and'serves as anaxis on whichit may be 'swung.. Vflhetwo Sections an of this split, pipe are fast-tocrossrpieces a? c3, which extend acrossV underneath the. fire-box 'and which are Supported by dependent arms d? c5,
which are fast toairinn a6 securedinftheturned and the. grate lowered-as .far as may re-bo';. `The grate is Supported inplace by the -cam .or eccentric 1B', on which' rests the K v v l A contents" of tirelire-box are to be du m pecl,y the cross-piecebfof ringb, whichfits over,'splitV pipe a n', as clearly Shown' in Figs'. 1 and 3.v

Fast theas'h-pit is required v Y to' fallout around the wallsdo so5'whi1ethe engaging projection d3, fast tothe grate-A.
The outer ends of arms b2 and d are preferably squared Oft to allow them to be grasped by a wrench. This modified form is especially adaptedV for use on parlor-stoves and the like, it making amore compact and a neater arrangement than'tbe form shown in Figs'l to 3.
It is obvionsthat that porti-on of the re in contactwith the walls'of the furnace and with the grate will iirst' die out-irst, because the heat is radiated more quickly, and, secondly, as to the grate, because combustion is iercest at this point, as it is the place where Oxygen is admitted. 4In some npright furnaces heretofore made when it has been desired to re,-
. movethis waste matter it has been accomplished by shaking the entire body of re, with the result lthat in removinga part of the be removed, which subsequently would removed, so that no' sifting of the contents of bnrnedfout material closeto the grate is lalso .easily dislodged', leaving the center of the fire undisturbed r'and clear;
