Specification of Letters Patent` Y f -gLAsT-FURNAcE-GHAHGING APPARATUS.
. Patented July 31, 1906.
I To dill' whom it may con/corra? f it known 4that I, WALTER'KEN'NEDY, .a
, citizen of the United States, residing at Bellevue, in the county of Alleghenyr and State of .5 Pennsylvania;
have invented or discovered lc 'ertainnew and useful Improvements in Blast-Furnace-Char imp n'rovemer'itsl the ollowingis a specification.
io' f It has 'been found that in charging a blastfu ace there will be a'separ'ation of the ma-.
' terialsflo' :g from theskip into the hopper of the fine and large lumps, the larger lumps being de osited on one portion of the bell and l r-"-the sma l onto another,
" 'charge similar distributionof the material as regards their size is made therein. As a consequence of'this-separation of the large from-the small 201 it is found that the furnace Awill `work un- 'evenly,
throughthe partwhere the larger lumps are so that when the.
is finally dropped into the .furnace a the 'blast passing up more freely collected.y
The vobject of the present invention is to 4'providefor an approximately even mixing and distribution of the large |and small lumps on the bellof the main hopper', so that when the charge is dro' ped there will be a corre-` di'stribution of the large and admixtur'e of the two jin' the furnace;
The invention is hereinafter more fully described and claimed.
' In the 'accompanying drawings, forming al partof this specification., Figure 1 is a view,
` the c arging apparatus o'n top' of a furnace;
-and Fig'. 2. isa sectional plan view` on a plane indicated. by the vline II. II, Fig. 1. 4o
In the practice of my invention the fur-I nace 1 ,with a mainhopper' 2, bell 8, skipway 4, and mechanism usualo'r any suitable manner` Onto of the 2 I arrange a receivingopper, which .may be of anyv suitable form or` construction,
main hop er, in the manner shown.; As
bands `5., yso Varranged relato eachother that thes/mall'lower end .tively large-'end yof one band kwill discharge into 4the ing Apparatus ,of which sage of for -raising'and loweringthe skip,is constructed and arranged in the C adjacent thereto, so that bility of the lateral discharge of the material. These bands are secured at their peripheries to a series of posts 6,.secured tothe main :hopperor resting thereon. The upper portion of the receiving-hopper structed in' a suitable manner, but isl preferably formed with integral walls, as shown. Byreason of this construction access can be had by a stirring-rod prevent anyl clogging ofthe material when the bell 7 is lowered to' discharge thematerial onto the bell 3 in the main hopper. lThe main hopper is supported b a rod 8,-passing up through the receiving-hopper and connected to an operating-lever 9. or other. suitable means whereby the bell may be raised and lowered. 'The bell 7 for closing the distributing-hopper is connected to a sleeve 10, surrounding the rod 8, and connected at its u per end to an operating-leveren 1, whereby t e '-bell may be-raised and lowered, 4as desired. A sleeve 12 is arranged outside ofthe sleeve `10 and extends up above the receiving-hopmeans of a co ar 15,- securedto the sleeve. To this sleeve at a suitable point within the receiving-hopperis secured an inclined plate point# A desirable construction to this end consists in making the' plate of such size that it extends lentirely across 'the hopper except as'to bell o 2.4v It is preferred to -construct this'distrib- --uting-plate in two-partsor sections, one part end of the next lower'band, but is' preferablyl i' there Will be no lia- 16, which 'is constructed'to-'prevent the pasmaterial .beyond it exceptl at one at 4one point, where the plate is cut away, 'son may be conor otherwise, so as to A perl and is supported byv ay cross-bar 14 by permit materialfto pass down onto the the receiving-hopper, asshown -in Fig.
Aor section beinglpreferably',formed of cast metal and'cosisting lof a hub with laterallyextending flange, as shown in Fig.
1, and to otherwise. 'This construction permits of the lbut is preferablyconstructed,` at least as `regards the portion adjacent to the terial charged thereon.
When the'm'aterial is ski .in t'o. the distributing-hop er, it will str1 e upon the inclined plate and) along thesame and onto the bell awayint of theplate or an opening made Ttheret ough for such urpose.- After one skip-loadhas been' disc arged yonto the bell lthe latterisglowered, so as tol discharge the below rIl he uppler band' needfnotnecessarilyproject below t e' upper material therefrom ontothe main bell 2. The
renewal of the portion ofthe plate which isl rapidly Worn away by the impact of themadischarged iromthe` this flange is secured a "steel plate by rivets or IOO pass down 7 at the cutbell of the distributing-hopper is-then raised, i
and at the same time the distributing-plate is rotated a greater or less distance, so that the next skip-load will be discharged at a different point onto the distributing-bell 7, and consequently at a different point on the main ployedfor effecting the opening and closing movements of the distributin -bell and the rotation of the distributing-p ate,'which is not moved vertically, it is referred that theA closing of the bell and the s lifting of the plate be performed simultaneously andl by the same mechanism. To this .connected to the piston of the cylinder 18, said piston being alsoconnected, as shown, to a lever 11 and asses around guide-pulley 19, `the grooved will the sleeve 12, thence around another guidepulley '21 to acounterweight, which is pref-p adjacent to the chargingerably arranged Hoor, so lthat the the furnace will gards the and plate.
men engaged in charging have an' indication as repositionv of the distributing bell A pawl-and-ratchet connection provided-between the loose wheel 20 and the sleeve 12, so arranged that when the lever 11 is shifted to lower the'distributingbell the rope 18 will be slackened, permitting the counterwei'ght to turn the wheel 20 without shifting the sleeve and plate. When the lever 11 is shifted to raise the distributingbell, the rope is so drawn as to raise the counterweight and rotate the wheel 20 and sleeve to shift the distributing-plate. When the distributing-plate is` shifted by the mechanism employed for raising and lowering the distributing-bell, the operation of the bellshifting mechanism should be uniform and provision should be made for adjusting the amount of rotation of the distributing-plate. To this end a tappet 22 issecured upon the portion of the rope connected to the piston of the cylinder, and a stationary sto 23 is connected or secured to the receiving-hopper or other suitable portion of the furnace. By this means the travel of the rope when drawn by the counterweight can be regulated by adj usting the tappet along the rope.
I claim herein as my invention l. In a blast-furnace-charging apparatus the combination of a main hopper and bell, a receiving-hopper, a distributing-plate arranged in said hopper whereby stock delivered to said hopper may be directed to one side of the hopper, means for horizontally shifting ysaid lplate and means movable independent of the plate for controlling the discharge of material from the hopper.
