` BLAST-FURNACE. A
Specification of Letters Patent.
Application filed November 19, 1909. Serial No. 528,865.
To all whom it may concern:
Be it known that I, CHARLES H. BRADLEY, a resident of Ensley, in the county of Jeerson and State of Alabama, have invented a new and useful Improvement in Blast-F urnaces; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to blast furnaces and has special reference to blast furnaces having a bell means for sealing same and for receiving materials to be charged into such furnace.
The object of my invention is to provide the novel arrangement, construction and combination of parts, as hereinafter more specifically set forth and described and particularly pointed out in the claims.
To enable others skilled in the art to which my invention appertains to construct and use my improvedblast furnace, I will describe the same more fully, referring to the accompanying drawing, in which--` Figure 1 is a vertical central section of the top portion of a blast `furnace having my invention applied thereto. Fig. 2 is a sectional plan of the same on the line 2-2 Fig. 1 and looking in the direction of the arrow. Fig. 3 is a side view of a portion of the same. ,V
Like symbols of reference herein indicate like parts in each of the figures of the draw- 1n s.
le illustrated in the drawings, 1 represents the upper end of the main or body portion 2 of an ordinary blast furnace having the ring 3 within `the same for engaging with the main bell l to form a seal 3 between the lower end of the same and said bell when such bellis in its closed position, as shown in Fig. 1. The bell 4 is connected in the usual manner to the lower end of the vertical rod 5 extending through and above the distributing device of the furnace, as
\ hereinafter described, and is operated in the usual manner by the ordinary devices connected to its upper end.
Connected to the upper end 1 in the usual I of open sections between and connected to the same for supporting the head 8 and guiding ring 11 and hopper 12 hereinafter described. Extending down from the upper head 8 and connected thereto is the upper guiding ring 11 and projecting up from the upper end of said guiding ring is the receiving hopper 12. Within the cover G and connected to the lower head 9 is the lower sealing and` guiding ring 13, which extends down from said head and acts to guide the cylindrical distributing receptacle 14 within the same,as well as acting to form a seal at 15 between the lower end of the same and said receptacle when such recepta- Patented Aug. 16, 1910.
cle is in its closed position, as hereinafter described. Viithin the receptacle 14 is the inclined chute 16, which extends across and forms the bottom of said receptacle, said chute being preferably scoop shaped and of `same width as the inside diameter of said receptacle at vertical center line of the same. This chute 16 also decreases in width and leads into an opening 17 at the lower end of the same and formed in the side `of said receptacle for intermittently discharging the` materials from the receptacle 141 when it is lowered, as hereinafter described. Connected to thechute 1G and centrally of the same is the vertical casing 18, which `leads up from said chute around the main bell rod 5 and is connected to a head 19. This head 19 is revolubly mounted on a sleeve 20 located above the hopper 12 by the ball bearing connection 21, and such sleeve extends around the rod 5, casing 18 and head 19, and
forms part of the usual operating rods 22 extending above said hopper;
Projecting down from the upper `head 8 are the blocks 23 and projecting up from the lower head 9 are the blocks 23', and these blocks 28 and 23 are suitably ribbed and removably connected `to heads 8 and 9 in any suitable manner by their base portions 24;.- The blocks 23 and 23 are preferably thirty (30) in number, fifteen (15) being of the furnace.
mounted on the head 8 and fifteen (15) being mounted on the head 9, and the blocks on one head are so arranged that they stagger with the blocks on the other head. `The opposite ends of the blocks 23 and 23 from the bases 24 are pointed, as at 25, while extending from such pointed ends to the base portions 24 on said blocks and on the same side of each of the same is the tapered or inclined face 26, and such faces are all inclined in one direction. Mounted on the lower head 9 are the bearings 27, which are each provided with a caster 28 for engaging with the exterior face on the wall of the receptacle 14, and such caster is preferably journaled in its bearing 27 away from the center line of the caster, as at 28, in the usual and well known manner. Extending out from the exterior face of the wall on the receptacle 14 are the hooked projections 29, each pair of which are adapted to support a 'bearing block 30 slidingly mounted within 'shown in Fig. 1, such bell is ready to catch and sustain the materials delivered thereto from'the distributing device 7, and then afterward to be fed into the body 2 ofthe furnace. This delivering of the materials to the bell 4 is accomplished by raising the i receptacle 14 through the usual devices con- V'nected to the upper end Yof the rods 22, to -which the casing 18 carrying the receptacle 14 is attached, and during such raising of said receptacle t-he rollers 31 on the same will engage with the inclined faces 26 on the upper blocks 23 to revolve said receptacle one-half the number of degrees desired,
such as in the direction of the arrow shown in Fig. 2, aswell as the casing 18 and the head 19 on the sleeve 20. By this turning of the receptacle 14 in the raising of the same, the opening 17 in such receptacle is rotated to lanother position from that shown in Fig. 1, and is closed by the guiding and sealing ring 13 in the raised position of such receptacle. In such raised position the receptacle 14 is sealed at 15 by a projecting ring 14 at its bottom being against the ring 13 and is ready for the reception of the material therein, which is dumped through fthe hopper 12 into the same and in the usual manner from cars raised from the bottom After the materials have been thus dumped into the receptacle 14 it islowered through the devices connected to the rods-22 carrying such receptacle through the casing 18, and in such lowering the receptacle is revolved the remaining number of desired degrees in the same direction through the rollers 31 on the same engaging with the inclined faces 26 on the lower blocks 23, so that the opening 17 in said receptacle 14 will again be rotated to another position, and as soon as such opening passes the lower end of the ring 13 in such lowering of said receptacle the material in the same will be ejected therefrom and down the inclined chute 16 onto the bell 4. The shifting or rotatable movement of the receptacle 14 is accomplished with only one-half of the distance desired in the raising of the same and the balance is accomplished in the lowering of the same.
In the vertical movements of the receptacle 14, as well as in the rotatory movement of the same it is guided by the ring 13 fitting around the same and by guiding ring 11 on the lower end of the hopper 12 within the same, and in such movements the said receptacle will travel on the casters 28 mounted on the lower head 9. The different kinds of materials that are generally used as stock for the furnace are thus each dumped into the receptacle 14 and delivered onto the bell 4 by the raising and lowering of said receptacle and by the intermittent rotating of the said receptacle in such raising and lowering movements of the same. hen such an amount of these materials is thus delivered onto the bell 4, such bell can be lowered by its rod 5 in the usual manner through the devices connected t0 the upper end of said rod and such materials thereby allowed to slide down the same into the furnace, after which said bell can be again raised to its closed position and the vertical raising and lowering and rotating of the receptacle 14 repeated in the delivering and placing of the materials on the said bell, so that these operations can be carried on continuously.
Itwill thus be seen that my improved blast furnace has a charging and distributing device for the stock or materials which combines both the upper bell and receptacle ordinarily employed, which will do away with a number of parts and devices usually found in this class of machinery, as well as eliminating complex and complicated operating devices for the same, and thereby cheapening the cost of manufacture and maintenance of these furnaces. The stationary inclined blocks being formed separately and of cast metal can be easily renewed when broken or worn, as well as the other operating parts of the device, and the inclined devices are ventilated and visible through the open inclosing ring frame, so that any difficulty therein can be seen at a glance and thereby easily and quickly remedied.
The number of inclined blocks and rollers therefor shown and described are considered the most practical for distributing the stock when the three materials ordinarily employed are used as such stock, and it is evii. dent that any number of such bloclrs and said bell adapted in its raised position to be sealed and receive the stock for the furnace and in its lowered position to deliver the stoclr, and means for rotating said receptacle to distribute the stock therefromfonto said bell in the lowered position of said receptacle.
