To (LU whont it riz-Ly concern' Be it known that l, ALnaon'r B. NEU- MANN, a citizen of the United States, residing at Joliet, in the county of Will and State oi 5 Illinois, have invented certain new and useful Improvements in Distributors for Blast- Furnaces, of which the following is a specilication.

The object of this invention is to provide 1o means which may he automaticallyr operatefh for evenly and uniformly distributing the charge introduced into a blast or similar furnacejso that the material may be thrown into the furnace fromA a single point and `will be evenly distributed when it finally falls into lace. Y

It as hitherto been customarv in charving a blast-furnace to carry forward the loads ol' material in wheelbarrows or similar conveyances and dump the saine into the hopper of the furnace on diiierent sides, so that the charge would not accumulate in one place, which would tend to impair the operation oi' the furnace and the quality of the resultintg.,t

2 5 product. This method of charging the iurnace is unsatisfactory for several reasons, in that it requires additional staging to be built around the top of the furnace and renders the char ing of the furnace by automatic means di `cult and uncertain. The distrib-V uter of the present invention enables the entire char e to be introduced from a single point an provides means for properly positioning the discharge during its descent into 3S the furnace.

The invention consists in thc features of construction and combinations of parts hereinalterdescribed and claimed'.

In the drawings illustrating the invention,

40 Figure 1 is a sectional view of the top of a blast-furnace, showinr the distributor of the present invention and means for operating the same; Fig. 2, a face view of the distributinglate, and Fig. 3 a side elevation of the upper ell and plate secured thereto; Fig. 4,

a side elevation, partly in section, of the rotating mechanism; and Fig. 5, a top or plan view of the clutch.

The furnace, as shown, is cylindrical in shape and consists of an inner Wall 1, converging sl' htly at its top, and an outer Wall 2, provide with a converging roof 3, leaving a. space 4 between the inner and outer Walls. The furnace iscovered on the outside by a' ets or other receptacles upto the inout-h of Vis elliptical in shape and extends diagonally 'chute to one side thereof.

shell or casing 5, and the roof of the outer Wall has entered thereinto a downwardlyconverging hopper 6, provided with a flange 7 around its open lower end, which flange forms a shoerider-abutment, u v)on which rests a funnel-shaped ring S, whicli forms a seat for a lower bell Q, which when in raised position closes the opening of the funnel-shaped ring and to retain the material dumped into the hopper. The hopper is partially closed at the top by moans of a sloping roof consisting of a lower section 1l) and an up er section 1l, the latter of which is provi ed with an inlet-opening l 2, in to which extends a chute 13, outwardly flared at its upper end 14, upon which chute is positioned a receiving-hopper 15 in suitable proxiinitiY to a staging 16, carrying a track 17 for carrying Mirkthe receiving-hopper, whence the)v are discharged thereinto. The discliarge-niouth of the chute lil is normally closed by Inca-ns of snapper or distributing bell 18 of conical shape, which is provided on one of its slo ing` side walls with a distributing-plate i9, w iicli 8o across the bod)r of the chute, forming a slide forrthrowng the material discharged into the The distributingplate is of suitable size and shape to substantially fill the entire passage of the chute, and its curvature is necessarily elliptical by reason of the fact that it is positioned in d1- agonal relation to the body of the chute.

i The distributing bell and plate are rovided with a hole or opening 20, throng which passes a tubular shaft or sleeve 21, provided near its end with an annular groove 22, which receives the bell, which latter is held in place by means of a ringer collar 23 on the end of the tubular shaftor sleeve. The lower bell is supported by means of a solid shaft 24, which asses through the tubular shaft and is moved independently thereof. The tubular shaft connects with suitable mechanism 25 for irnparting a partial rotation thereto, and said mechanism, as shown, consists of a casing 26, into which the tubular shaft enters, and said shaft has secured to its end a gear-Wh el 27, having teeth on. its periphery 28, Whi imesh with a pinion 29, and teeth on its u per face 30,1vhicli mesh with a pinion 3l on t e end of a shaft 32, which is provided with a universal joint 33 to adapt it to rotate under alli-roum- IDO y slope of the distributing-plate.

shaft 8.4, having therein a universal joint 35,

and said shaft is provided with a spirally-extendinr groove or channel 36, whlcli passes throng i a clutch 37, which is rigidly secured to a cross-head 39, which carries the inner shaft 24. The clutch consists of a casing 38, having a closing disk or plate 48, and the lower wall of the casing and the closing disk are perforated for the passage of the shaft 34, the edges of the two perforations being provided with inwardly extending annular flanges 49 and 50, respectively', which have their edges 51 concaved to rovide a seat for the clutch-ball 52, which atter is provided with a ring of s rocket-teeth 53, which cooperate with a og 54, which is held in engagement with the teeth by means of a spring 5.5, allowing the clutch-ball to run freely in one direction and holding it against rotation in the other. The casing 26 is adapted to be raised and lowered b means of a chain 40, connected to the en( of a pivoted counterbalance-arm 41, having thereon a weight 42, which allows the casing and mechanism therein contained to be lnoved up and down the inner shaft as a guideway and the outer or tubular shaft and bell attached thereto to be raised and lowered independently of the o eration of the inner shaft which supports tliie lower bell. To the cross-head 39 are secured rods 43, which pass through guidewaysv 44 and connectwith an upper cross-head 45, which is secured to a iston 46. o erating Within a hydraulic cyhnder 47, w lich furnishes power to raise and lower the lower bell which controls the direct discharge into the furnace.

In operation the material to be introduced into the furnace is dumped in the receivinghcpper from the track 17 at the right-hand si e of the ho per and falls down against the distributing-diete, which when turned to the osition shown in the drawings will throw own all of the material to the right-hand side of the distributing-bell by reason of the After this portion of the chute has been sufficiently lled the bell is lowered by raising the counterbalance-arm, and the iirst char edropped from the distributing-bell will fill te space to the right of the lower bell, after which the distributing-bell will be raised into position; but the outer sleeve and bell will be turned a quarter-revolution to bring the distributingplate to a position at right angles to that previously occupied, so that the second charge will be deposited in a different position, after which the o eration is repeated and the char e is distri uted around the lower bell and (glischarging-hopper preparatory to their introduction into the furnace.

The mechanism herein shown for turning the upper bell operates as follows: As the tubular shaft supporting the distributing-bell and the mechanism secured thereto descend the spirallyrooved shaft 34 will be drawn down throng the clutch-ball 52, which in this position is released and allows the shaft to slide free without revolvin the pinion 29. When the bell is again raise the dog will engage the sprocket-teeth and hold the clutchal, whic being held rigid, will act in the spiral groove and turn .the shaft and pinion 29, which imparts a partial rotation to the gearwheel 27 and serves to revolve the tubular shaft or sleeve a partial revolution, which may be a quarter or any other suitable fraction of an entire revolution, so that the distributing-plate when fully raised will stand at a different position preparatory to receiving a second charge. It will be understood that while the charge is being distributed the cross-head 39 and casing 38 for the. clutch mechanism will remain stationary or rigid for the urpose of revolving the spirally-grooved shaflt); After the char e has been fully distributed around the ower or discharging hopper the hydraulic c linder and piston can be operated to lower t e shaft 24 and lower bell, allowing the complete charge equally distributed to slide into the furnace. As the gear-Wheel 27 is revolved it will likewise revolvo the bevel-pinion 31 and shaft 32, which revolution is transmitted to a pointer, (not shown,) the position of which serves to indicate to the operator the position cf the distributing-plate, so that it will be possible to tell at a lance how manv times the distributing-bell las been lowered and how manyloads have been dumped into the lower hopper.

AIt will be seen inthe foregoing description tllat the device is extremely simple in construction and operation and that it entirely dispenses with the necessit for providing a staging all lthe way arounr the to of a receiving-hop er or the layin of trac and the discharge o material from different points in order to distribute the material. AL the same time the operation of the parts is done automatically, as it were, and the charges will be more accurately distributed than would be possible if dumped from wheelbarrows or similar receptacles.

The partlcular construction of furnace and hopper herein shown serves the purposes of illustration; but it will be understood that the distributing-bell is ap licable to different styles of furnaces and di erent constructions of hop ers from that herein shown and described? What l regard as new, and desire to secure by Letters Patent, is
