Application filed August 19, 1914. seriaiNo. 857,511.

To all whom it may concern:

Be it known that I, JOHN T. BATEs, a citizen of the United States, residing at Pittsburgh, in the county ofAllegheny and State of Pennsylvaniinhave invented certain new and useful Improvements in Furnace-Botting Apparatus, of which the following is a specification.

My invention relates to the construction of apparatus by which the cinder notch or cinder tapping hole of blast furnacesv is plugged or closed and the invention more particularly relates to the construction of the botting bar and bar operating mechanism used in actuating suchbotting apparatus.

One object of my invention is to provide a furnace botting apparatus having improved means whereby the botting bar is secured and maintained in operative position.

Another object of the invention is to provide a botting apparatus having novel means showing a furnace botting apparatus constructed and arranged and applied thereto in accordance with my invention. Fig. 2 is a transverse sectional elevation of the same, I

ried to ad ust the botting arm 12 and bring the section being taken on the line IIII of Fig. 1. Fig. 3 is a similar transverse section, on the line III-III of Fig. 1. Fig. 4 is a detail plan showing the construction of the swinging outer end of the botting bars forming part of the apparatus shown in Fig. 1. Fig. 5 is a longitudinal section showing a modified form of botting bar as made in accordance with my invention.

In the accompanying drawings the nu- .meral 2 designates the cinder notch or cinder tapping hole of a blast furnace 3. The taping hole is provided with a cooler '4, monrey cooler 5 and cinder monkey 6- which, as

shown, are of the usual known construction.

Above the tapping hole 2 and in vertical alinement therewith is a horizontally extending beam or girder forming a support 7 having one end thereof secured to the furnace 3 and the other end fastened to the conveniently located furnace bustle pipe 8. P voted at one end to the support 7 by a plvot p1n9 is a depending lever 10 made in 8801310115. The lower section 10" thereof has its lower end pivotally connected by a pin 11 to an intermediate point in the length of the swinging botting arm 12. A second lever 13 having a bent upper end 14 and having a rectangular slot 15 therein adjacent to the bent end 14 also is pivotally attached by a bolt or pivot pin 16 to the support 7, and I this lever 13 also is made in sections, the

lower section 13 being pivotally connected by a pin 17 to an intermediate point in" the length of'the arm 12. The slot 15 in the upper end of the lever .13 is pro ided witha *pivot pin 19 which extends through the'slot and is fixed on the sup ort 7. The support 7 has a curved slot 6 therein, through which the pivot pin 16 extends, this pin belng fastened to the outer end of the bent end 14 of the lever 13. I

- The-botting arm 12 hasa botting bar 20 pivotally secured thereto, the bar-20 being p voted at one end by a pin or bolt 21 to the arm,by a taper pin 22 removably secured in holes in the ears 23 forming a keeper which is provided adjacent to the end of the arm 12 for that purpose.

The ove r-lapping ends of the lever sections 10 and 10 and the lever sections 13 and 13 have slots 24, 24 therein, through which bolts 25' extend to fasten the lever sections together in adjusted position and to enable the length of these levers to be vathe botting bar into alinem ent with the cinder notch 2.

Instead of using a solid botting bar'20' like that shown in Figs. 1 and 4, the hollow water cooled botting bar 26 shown in Fig. 5 may be employed. In this construction, the botting end ofthe botting bar 26 is fastened to the screw threaded end of a hollow member 27, the member 27 having a threaded ios . o 'enin ,31 afi 'ords means I for supplying. water o rother cooling fluid through the pipe 30 tothe nose 29 of this botting bar and anoutlet opening 32 affords means for conducting thecoolin'g fluid from the'hollow water cooled botting bar'26.

The apparatus is arranged to I. swing by gravity into the position relative to the'cmder notch as shown in the.'drawings and guide bars 33 and 34 are provided on the.

support 7 to prevent transverse swinging of the arm 12.

. A rope, or other flexible connection 35 is attached. to the lower section-10 of the 5 swinging lever 10 to provide meansfor moving the arm 12 and botting baror when used, the bottingbar 26- from the position shown'in full lines into that shown in dotted lines or from the cinder notch closing position into position out of the way of and from in front of the cinder notch by. an operator stationed at a remotely located point. The inlet opening 30 and outlet opening asiis shown in Figs. 1 and 2 or a Water cooled botting bar 26 like that shown in Fig. 5 is pivoted by the bolt 21 to the bot- "ting arm '12. Meanwhile the botting arm and botting bar will be held in'its retracted position (shown by doted lines in Fig. 1) by means of the flexible connection 35. When it it desired to open the furnace cinder notch 2, to tap off the cinder -or "fiush the furnace, the botting bar 20 is 'pulled backwardly by grasping the botting arm 12 or by pulling upon the connection 35 to. move the bar 20 away from the furnace,

a winch or winding drum (not shown) which is'attached to the-flexible connection usually being employed for this purpose.

When the botting bar 20 is moved backwardly into its retracted position, the lever 10 swings backwardly in the arc of a circle, with the pin 9 by which it is'pivoted to'the support 7 as. a centers The other lever 13 moves upward-1y on the pin 19 in the slot 15 the length of the slot'and then the pivot pin 16: on the outer end of the bent end 14 of the lever 13 moves downwardly and traverses thecurved slot 36 in the support ,7 upon end of the botting bar 20 or 26 moves in a substantially horizontal plane.

in the upper end thereof for a portion of further backward swinging movement of it is desired to close the tapping hole 2, the flexible .connection 35 is released and the weight of the suspended portions of the apparatus moves the botting bar 20 from the position shown in dotted lines until 7 the botting bar is substantially horizontal and then movesthe bar forward in a general horizontal direction until the botting end.

of the bar 20 is again inserted in the cinder monkey 6 w1th1n the cinder tapping hole.

' The botting bar 20 then remains in this position until it is again desired to tap cinder from the furnace when the above described operations are again repeated. When .desired, the pin 22 in the keeper 23 on the end 3 of the botting arm 12 is remoged and the botting bar 20 is swung on the pivot 21 to move it laterally out of the-way of, or from in front of the cinder tapping hole 2.

The operation 'of the apparatus will be 3 5 the same as has been described when the water cooled botting bar 26 is employed. In

,such case however flexible connections to the inlet 31 and outlet 32 will be provided in order to conduct cooling fluid to the hol- 'low botting bar and'to carry ofi the'waste fluid therefrom.

The advantages of myinvention will be apparent to those skilled in the art. By the use of my improved apparatus the operation of tapping or opening and stopping or closing the cinder notch of blast furnaces is easily and quickly performed.

Instead of opening the tapping hole by means of a manually actuated bar, the apparatus is operated from a remote point, away from in front of the tapping hole, and out of the way of flying particles of hot cinder. The apparatus is simpleand is easily kept in repair; a I Modifications in the construction and arrangement of the parts may be made without departing from my invention as defined in the claims. I v
