intoplace. This.

'portant a Itis customary to shovel this col ie into the pits by hand and then scrape or poke it is an extremel hot and laborious task, and it is diflicu t for the workmen to lace the coke in the bottpin of the pit to thegiest advantage. It is desirable that'the coke be thrown against the walls of the pit for. the purpose of protecting the latter. At the same time it is desirable that .the coke be so laced as to make a trough ation'of slag and also proof the ingots in the pits. It is very imso that the distribution of the coke dust ove the bottom be-uniform, that is to say, it should not be piled high on one 'vention is to facilitate side and low on the other. n

One. of the ob ects, therefore, of my inthe proper covering of the bottom of soaking-pits.

4 Another object is to preserve the walls of soaking-pits.

Another object is to deposit coke dust in the soaking-pits in a manner to properly accumulate all the slag.

Generally speaking, jects are accomplished by providin a portable hopper for discharg ng coke ust into soaking-pits, including a bottom for causing the contents of the hopper'to be discharge towardthe walls and toward the middle of the it; p T e invention is illustrated on the accompanying sheets of drawings, in which- Figure 1 is a sectional eleyation of my hopper shown in connection with" a soaking pit; and, Fig. 2 an enlarged scale.

the hopper in the ho per is these and other obis a plan view of the hopper on The various novel features of the inven tion will be apparent from the following description anddrawings and will be particularl pointed out in t e appended claims.

y ho per 10 is provided with 9. rec-' ortion including four walls the body portion of the hopper are laterally extending arms or frames 18 and 19 whic are adapted to rest res 'ectiv'ely. he hopper is adapted to swing froma crane bymeans of a ail 22 secured to two ieces 28 which are connected to each other m intersectin planes. These two pieces 23 ca vertica ly extending members" 24, a) the ower ends of which members is secured the hopper-bottom 25. Thisho per bottom includes two s aced peaked members 26, each of which is a a ted to shed the contents of aterally opposite directions toward the walls 27 and toward the middle of the soakin it 28 over which the hopper proper may removable downwardly from the'bo y portion of the hopper, whereby the contents of the hopper may be deposited readily into the ,pit 28.

By-means of a crane, the hopper is carried 7 to the pit loaded with coke dust and lowered into a position such that its laterally ex-.

guided manner. The coke ,du'st which asses outwardl over the sides of the peaks 26 in the bottom is charged against the sidewalls of the pit to h the cuttii'i action of the sla and-the heat.

protect the same against radiatedz' 'na the hot i etc which later are deposited in the pit.

t the same time ottom of the.

out from the hopper in a When the crane lowers an inthe coke dust which is discharged inwardly over the inner shedding surfaces of the peaks 26 is directed toward the middle of the pit. As a result of this guided discharge of the coke dust from the hopper, the coke dust is piled somewhat higher at the sides and at the middle of the pit running longitudinally thereof and forming therebetween suitable trough portions29 for the accumulation of slag and the proper placing of ingots. Generally speaklng, the coke dust 30 is automatically distributed quite uniformly over the bottom, there being no positing the lowering the bottom to permit the contents necessity for the workmen to rake or otherwise distribute the coke in a less efiicient manner.

This method of distributing coke dust in soaking-pits greatly simplifies and improves formermethods, and consists in filling the hopper havin a removable bottom, then deopper over the pit, and then of the hopper to be distributed in a given 'manner. It will be noted thatthe {topper as a unit is suspended from the ottom thereof.

There may be various modifications of ne invention herein particularly shown and described, and it is my intention to cover all such modifications which do not involve a departure from the spirit and scope of the invention as set forth vin the followin claims.

-I claim: 1. The herein describedmethod which consists in supporting a quantity of pulverulent lining material at the open top of a; soaking pit, showering the supported material down upon the bottom of the pit and at the same time directing the material to form a trough of the material upon the bottom of the pit.

2. The herein described methodwhich consists in supporting a quantity of pulverulent lining material at the open top of a soaking pit, showering the supported material down upon the bottom of the pit and causing the material to hill up around the side walls of the pit.

3. The herein described method which consists in .supporting a quantity of pu1ver-' ulent lining material at the open top of a soaking pit, showering the supported material down upon the bottom of'the pit,;and

- causing the material to hill'up around the .verule'nt lining materia side walls of the pit and also diametrically across the bottom of-the pit to form troughs at opposite sides thereof.

4. The herein described method of lining soaking pits while in aheated. condition, which consists in ta-kinig an amount of pulbottom ofthe soaking pit and supporting said material at the showering the'material down upon the botof the sufficient to line the 'open' top of the pit,

the material to-cm'er the entire bottom area of the pit. 1

5. The combination witira soaking pit, of portable lining distributing means supported over the mouth of the pit-and including a hopper to contain a supply of pulverulent lining'material, and mechanism for distributing the pulverulent material from the hopper and upon the bottom of the pit as a lining for said bottom.

. 6. The combination with a soaking pit, of

portable lining distributing means supported over the mouth of the pit and including ahopper to contain a supply of pulverulent lining material; and mechanism for distributing. the pulverulent material from the hopper andupon the bottom of the pit as a lining thereof and in a trough formation on the bottom of the pit.

7 The combination with asoaking pit, of

portable mechanical means for distributing pulverulent material within the pit as a li1img for the bottom thereof, and including a frame to rest at opposite sides of the pit, a hopper carried by the frame, and a distributing hopper-bottom capable of being lowered with respect to the hopper to discharge the contents of the hopper into the pit. 8. The combination with a soaking pit, of portable mechanical means for distributing pulverulent material within the pit as, a lining for the bottom thereof, and including a frame to rest at opposite sides of the pit. a hopper carried by the frame, a distributing hopper-bottom capable of being lowered with respect to the hopper to discharge the contents of the hopper into the pit, and a hoisting element associated with the hopperbottom, whereby the hopper may be transported and the hopperbottom lowered and raised with respect to the hopper.

9. A portable distributing hopper for soaking pits, comprising a hopper body, hopper supporting means carried by and ex ten-ding laterally outward from the hopper body and adapted to rest-at opposite sides open top of a soaking pit and support the hopper over the top of the pit, a distributmg hopper-bottom capable of being lowered with respect to the hopper to discharge the contents of the hopper, and a hoisting element associated with the hopperbottom whereby the hopper-bottom may be raised and lowered and the hopper transported. 1

of the pit to supply pulverulent lining ma- 1 means to guide and direct the 1 tom, said depress'ble closure and t e open bottom of the hopper being provided with cooperating means to guide and direct the discharging material and. cause the same to hill up around the upright walls of the pit and across the bottom t ereof and form lining material into one or more troughs.
