. Be it known that I, JOHND. HUGH, acitizen of the United States, residing at Baltimore city, State of Maryland, Vhave -invented certain new and-useful Improvements in FurnacefStock Distributers, of which the following is a specification.

.This invention comprises means for dis- 1n charging-rece fr tributingthe stock evenly tacles, -as the `hoppersof blast-furnaces. 'T e utilized vin other apparatus in Which materials are to'be evenly distributed, wherein several, different kinds of materials are required tofbemiXed more or less unifi formly.

By means of the. fractional turningofthe bucket, Whichis accomplished auto- I IOO 28'is `shown in Fig.k l-farranged centrallypver i It has` an inclined bottom 2 9 hopper land isv adapted to Vdisch-arge Vvthecon-fV i -IIO which run on a circular rail or ring 33, the bucket being thus supported on said ring. The ring 33 is supported on trunnions 34 35, being part of said ring and having bearings in brackets 36 on the forward end of a car 37. These trunnions insure the bucket always hanging in a vertical position independent of the position of car in traveling to and from source of supply. The 4car is simply aframework suitable for carrying the bucket and provided with two airs of wheels. The forward or up 'er whee s 38 run on rails 39, while the rear or ower wheels 40 run on rails 41 of broader gage. The upper ends of the rails 39 are curved over the furnace and terminate in upward bends 39, which form stops for the forward wheels, and the rails 41 have branches 42 at their upper. ends which guide the wheels 40, the wheels 40 being prevented from leaving the rails 41 by means of therails 42. The curved connecting portion 41a of the rails 41 42 form stops for the wheels 40. The car 37 may be operated by a cable 43, running over a sheave 44, or by any other suitable means for elevating a car. When the car reaches its yuppermost position, in which the wheels are retained by the bends 39a 41a, the bucket will be located centrally over the hopper 14, as shown in Fig. 1.

I provide means for rotating the bucket automatically through a portion of a circle between successive discharges. This rotation may be effected just before or after the discharge of the bucket or at any time during the travel of the bucket from the hopper to the source of supply of material and back again. As shown, the. bucket is rotated step by step by the following means: Upon the bucket, below its supporting-wheels 32, is a bevelgear 45, extending entirely around bucket. In mesh with this gear is a bevelpinion 46 on a shaft 47, extending centrally through the trunnion 3-5 of the ring 33. Upon the shaft 47 is fixed a ratchet-wheel 48, and loose upon the shaft, outside of the ratchetwheel, is a gear 49. The gear carries a pawl 50, which is adapted to engage with the ratchet-wheel 48 when the gear is rotated in one direction and which rides freely over the teeth of the ratchet-wheel when the gear is rotated in the opposite direction. The gear 49 is adapted to intermesh with a short 'curved rack 51, arranged on a part 52 of the fixed frame. The rack 51 is parallel with the curved path in which the trunnions of the car travel in approaching their central position over the hopper 14.

The operation of rotating the bucket step by step is as follows: As the car 37 is lowered from the position shown in Fig. 1 the gear 49 is rotated by the rack 51, and the bucket is thereby rotated through v'a fraction of a circle f by means of the pawl-andratchet connection described, the shaft 47, pinion 46, and gear 45, the bucket traveling 'on the ring-rail 33.

The bucket retains the position to which it is turned while it travels to the source of supply of stock and back to the hopper. As it approaches the hopper it will not be affected by the rack 51, as the reverse movement of the gear 49 simply causes the pawl 5() to ride freely over the ratchet-wheel 48. It will be understood that by simply reversing the ratchet-wheel the bucket would be turned as it approaches the hopper; but this is notso desirable, as it is preferable to turn the bucket while it is empty.- It will also be understood that my invention consists,broadly, inmechanism for rotating the bucket to enable it to discharge its contents at different oints regardless of the particular devices emp oyed.

Without limiting myself to the construction and arrangement shown, I claim- 1. The combination with means for con- Iveying a bucket to and from a receptacle, of Ia bucket sup orted by said means, means for discharging t e contents of the bucket later ally, and means for turning the bucket to in 'sure the discharge of its contents in different directions. 2. The combination with a receiving-holy)- er, of a bucket, means for conveying tie bucket to and from the hopper, means for discharging its contents at one side of the hop er, and automatic means for turning the buclet to insure the deposit of the dscharged material at different parts of the hopper. 3. The combination with a receiving-hoper, of a bucket, a car upon which the bucket 1s carried to and from the hop er, the said bucket being rotatably mounte on said car, and means for rotating the bucket between successive discharges thereof, said bucket being arranged to discharge its contents laterally with respect to the axis upon which it turns. 4. The combination with a receiving-hopper, of a bucket, a car upon which the bucket 1s carried to and from the hop er, the said bucket being rotatably mounte on said car, means for rotating the bucket between successive discharges thereof said means comprising a rack and gear, and a ratchet connection between said gear and the bucket, said bucket being arranged to discharge its contents laterally with respect to the axis upon which it turns.

5. The combination with a receiving-hopper, of a car, a ring carried by the car, a

ucket supported by wheels or rollers upon sai-d rin and automatic means for rotating the buc et, for the purpose set forth, saiv bucket bein arranged to discharge its contents lateralIy with respect to the axis upon which it turns.

6. The combination with a receiving-hopper, of a car adapted to travel to and from the furnace, a ring having trunnions mounted on said car, a bucket supported by suit- IOO IIO

able wheels upon said rin and rotatable i thereon, a fixed rack in t e -pathv ofthe bucket, yand gearing operated by said rack and adapted to turn the bucket', rfor the purpose set forth, said bucket being arranged to discharge its contents laterally with respect to the axis upon which it turns. l

7l' The combination with a receiving-hopper, of a car traveling to and from said hopper, rails for guiding said car, means for stopping the car in proper relation to the hopper,

veying a bucket to and from the top of a furnace, of a bucket having an opening arranged to discharge the contents laterally therefrom, said bucket rotatable upon its vertical axis.

9. The combination with a receiving-hopper, of a bucket, a car upon which the bucket is carried to and from the hopper, and means for moving the bucket relatively to the car between successive discharges thereof, whereby the bucket is'made to discharge its contents successively to different parts of the hopper.

10. The combination with means for carrying a bucket to and from the receivinghopper of a furnace, of a bucket, and means whereby to discharge the contents of said bucket laterally therefrom in different posiv tions. v

11. The combination with means for carrying av bucket to and from the receivinghopper of a furnace, of a bucket provided with lateral discharging means, and. means whereby to Adirect the discharges successively in different positions. Y

12. The combination with a car and means for carrying it toward and I from the top of a furnace, of a bucket mounted on the car and provided with a discharge-opening, and ymeans for directing successive discharges fipm the bucketfin different positions latera lf3. The combination with a car and means for carrying it toward and from the to of a furnace, of a bucket mounted rotatab y on the car and provided with a lateral dischargeopening.

14. The combination with a car and means Lfor carrying ittoward and from the top of a furnace, of a bucket-mounted rotatably on the car and provided with a lateral dischargeopening, and means for automatically turn'- n ing the bucket a part rotation on each travel rof the car.

In testimony whereof I have signed my l' Aname to this specification in the presence of two subscribing witnesses.
