This invention. relates broadly to charge feeding; and distributing mechanism for blast furnaces. More particularly, it has to do with the. provision-of an anti-friction sup portingstructure or; mountingifor the hopper.

which operatesin.conjunction with the usual no provide for the ready replacement or repair of such parts as. are. subject to wear or most likely to become unserviceable. To these ends Iihave provided an improved anti-friction: support. or'monnting for the revoluble hopper of. a distributor which consists essentiall'y'of a number of separately removableroller; units that have: been specially designed for. excluding: dust. and facilitating the making ofany necessary repairs or; replacementsa. I have also provided,.for. coaction with saidxrolleraza tracker race of such. design that. its replacement or repair is also facilitated, andthus theentire structure rendered more dependable and convenient to service without material interference with the continuance of blast furnace smelting operation;

In the accompanying drawings wherein one embodiment of my invention is illus- 9 trated and wherein similar reference numerals designate corresponding parts in several views:

Fig. 1 is a fragmentary elevational view showing my improved mounting for the rev- I =5 oluble hopper of the distributor and also one form of apparatus for driving and controlling the movements of such hopper; Fig. 2 is a fragmentary plan view showing one of the removable roller units in its relation to other parts of the mechanism; and Fig. 3 is a 1928; Serial No. 276,633.

Fig. 2, and showingindetail theconstruction of one of the several identical roller units. and the track or race. with which it. co-operates.

Inthe drawings, and with particular ref erence to Figs. 1 and 3, my invention is shown in'association with a gas seal orcover 1, which may form the. upper part of the. usual two vertically disposed hoppers on top of the. blastfurnace stack Mounted upon the cover 1 is aflanged. neck piece 2' thatv carries an annulusor basemember 3. having oppositely extending parts 4i and.5.. The part 4 constitutes a flange from-which project aplurality of radially arranged brackets 6 that. are. designed for supporting the roller units or hopper bearings hereafter described. The part 5 of. base member. & extends. inwardly and forms one of two complementary gas obstructing flanges 6. and 7 for assistingiin preventing the escape oflgas from the lowermost hopper and from;the. furnace. The flange 7 projects laterally. from. the cylindrical bell seat member 8 which may have a telescoping relation with theneck piece 2, and whose top may be providedlwith a second flange 9 for a purpose to be hereafter explained. The bell seat members, togetherwith its extension 10; constitutes a distributor for' feeding raw materials. past the bell gate (not shown) and into the lower hopper from which'such materials may pass directly into the stack of the furnace. Loosely encircling the bell seat member 8' may be a segmental sealing ring 11 thatrests upon the flange 6 and supplements the action of the two complementary flanges Band"? in preventing tlieescape of gas.

Removably secured'to the flange 9 of" the bell seat member 8 is an annular gear 12. This gear, and. therefore the distributor to which it is attached may be given suitable movements, either rotary or oscillatory, by an intermeshing smaller gear or. pinion (not shown) that receives its motion from an electric. motor 13; through a universal coupling Hand encased worm .andworm wheel reduction: gearing,. this drive, the brake 15 and motor controllinglimit switch. 16.. being. pref; erably assembled asaunitwith the base. memher 3, all substantially as described in prior United States Patents Nos. 1,563,424 and 1 622,461 to A. G. McKee, respectively dated 15cc. 1, 1925 and March 29, 1927. The gear 5 12 may be provided with a circumferential channel or roove 17 for receiving artof the thickness 0 a track or race 18 w ose lower face 19 operates against or in contact with revoluble rollers 20, of which there may be any desired number, say six, spaced around the outside flange of the base member 3. It will be understood that the track 18 may be of detachable design, it being secured to the gear 12 in any approved manner, as for exam le by stud bolts 21. For maintaining the belfseat member 8 in properl centered relation to the neck piece 2 and base member 3,

the track 18 may have its inner edge provided with a shoulder for contacting with the similarly shaped inner edge of the rollers 20, this shoulder also assisting in obtaining a pro r adjustment of the rollers 20.

e rollers 20 may be secured upon shafts 22 in any suitable manner and prevented from 95 moving le thwise thereof by split rings 23 or the like. he roller shafts 22 may be journaled in roller or other suitable bearings 24 positioned in sleeves 25 in boxes or housings 26, such boxes being preferably provided with so caps 27 and 28 for their outer end closures and inwardly directed flanges 29 and 30 for fitting closely'to the shafts 22 in order to exelude dust and confine the lubricant injected through tubes 31 or otherwise supplied to the bearings. For taking the shaft end thrust incident to the inclination of the line of contact between the rollers 20 and their track 18, as well as for making possible some longitudinal adjustment of the shafts 22, there may be provided some such arrangement as thrust blocks 32 regulated by screws 33 and secured in any adjusted position by nuts 34. As shown in Fig. 2, each pair of boxes 26 may be formed in one iece with a bearing block 35 having lugs 36 t at may be bolted or otherwise secured to the base member 3. These blocks are preferably separate from each other and removably secured to the brackets 6 of the base member 3 so that in event of the failure of an one or more of the rollers, their shafts or earings, the objectionable or defective unit can be removed and immediately replaced by a spare or extra block of the same kind. This can be accomplished, as can be seen in the drawings, particularly in Figs. 1 and 3, by merely unfastening the block and removing it laterally, it being unnecessary to elevate, move or otherwise disturb the relative positions of the bell seat member 8 or the base member 3.

It will thus be seen that my invention provides for easily making any necessary corrections in the distributor mounting while at the same time obtainin the advantage of sim- 5 ple design and depen able operation due to the exclusion of dust and other abrasive materials which might damage the moving parts.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means he em loyed.

therefore particularly point out and distinctly claim as my invention 1. In blast furnace chargin mechanism, the combination of a revolub e distributor having a radially inclined annular track provided with an annular flange, a conical roller beneath said track in engagement therewith and said flange for radially and axially supporting said distributor, a journal pin carrying said roller, 8. housing adapted to receive the end of said journal pin, brackets united integrally with the base member for supporting said housing, said housing adapted to be removed from said bracket.

2. In blast furnace chargin mechanism, the combination of a revolub e distributor having a radially inclined annular track, an axially extendin flange united integrally with the inner e ge of said track, a conical roller beneath said track for supportin said distributor and adapted to enga e said ange, 06 a journal pin for carrying sai roller, a removable housing adapted to receive the end of said journal pin, a bracket united integrall with the base member for supporting said ousing, and said housin adapted to be removably connected to said racket.

3. In blast furnace charging mechanism, the combination of a revoluble distributor having a radially inclined annular track, an axially extending flange united to the inner edge of said track, a conical roller beneath said track for supporting said distributor a shoulder formed on the reduced end of said roller for contacting with the axiall extending flange of said track, a 'journa in for carrying said roller, a removable ousing adapted to receive and rotatably support the end of said journal pin, a bracket united with the base member for supporting said housing, and said housin ada ted to be removably connected to sai brac et.

Signed by me this 8th day of May, 1928.
