ALBI'N a. .wirrmc ianan'rnun 0. man, or cniciico', ILL-mole AUTOMATIC nxrnosion on ma as. VALVE non BLAST-FURNACES.
Specification of Letters Patent,
latent'ed'Nmr. :10, IQQS.
. Application filed August 1,1908. Serial No. 446,503.
To all whom it may concern: Be it known that we, Armin G: VITTING andAmnUR 0. Barn, both of Chicago, Cook count Illinois, have invented a new and usefu Automatic Explosion or Bleeder Valve for Blastl1urnaces,-of which the fol- .workin closes the bleed 'ers.
' tfiuantities of ore and coke,
lowing is-a full, clear, and exact description, reference being had to the accompanying in whic Figure 1 is a side view of the upper portion of a blast furnace having our invention a lied thereto, portions of the bleeder pipes on valves being shown in section Fig.2 is asectional elevation of our improved valve ap lied to a hleeder pipe.
y reason of the slips or explosions which more or less frequently occur inblast furnaces, they are usually provided with safety or blecder pipes havin closures, int-he form of a hinged valve, iv ich are so arranged that when the pressure inside the furnace suddenly increases the valves are liftedfrom their seats so that the as escapes and the pressure is reduced. hereafter the valve 15 again seated by its ownweight and sion, the gas is. sometimes followed by large which'are' also i'rown out through these valves, thereby causing a considerable loss and adding to the running expenses for cleaning up, as well as being a source of danger to the men around the furnace.
The c ject of our invention is to eliminate this objectionable feature of these valves, and to provide means which will prevent ore and coke being thrown out with the escaping gases. To this end, weprovide the bleeder pipes with valves having guards attached thereto, and so arranged that when the valves are opened by increase of pressure within the furnace, the guards will act to permit the free escape of gases fromthefurnace but will prevent t e escape of ore, coke, etc.
The precise nature of our invention will be best understood by reference to the accompanying drawings, in which we have shown one embodiment thereof, and which will now be described, it being premised, however, that various changes mag be made in the details of construction an arran ement of the valves and guards therefor'wit out departing from the spirit and scope of l l have illustrated two, drawin s, formingpart of this specification,
After 'a slip or explo-' on the seat 7 and thereby closing the bleeder do the fur- 3 the charging mechanism thereof, and 4 theusual superstructure. 5 designates bleeder pipes, of'which we although any desired number may be employe fltlesignates a, cone-shaped valve, which, .normally rests against a seat/I on the upper coses end of the blecder pipe 5 and thereby the numeral 2'desigsaid ipe. This valve is shown as being our ried y 'abar or cross-head 8 having .=depe ndingguide rods 9, which work through guide projections 10 securedto the exterior of-the bleeder pipe and carrying cushion s rin '11 above and below such. projections 'y w 1011 the movements ofthe valve are cushioned.
Depending within the upper portion of the bleeder pipe from the bottom of the valve 6 is a guar 12, which is also preferably in the form of a cone with i'ts apex upwardly, and which-is connected at its apex with the truncated portion of the-valve 6 by stem 13. The diameter of the cone 12 is suificiently' less than the interior diameter of the bleeder e to leave a surrounding annulars ace 14 between the edge of the bottom of t e cone and thcinterior wall of the pipe. The uppcrportion 15 of the pipe 5"wliich carriw the valvev seat 7 is also of conical interior form, so that when the guard cone 12 is raised to the position shown in dottedlines in Fig. 2, the space surrounding'the said cone will be substantially of the same area as that of the annular space 14.
The normal position of the parts is as shown in Figs. 1 and 2, the-valve 6 resting pipe; When the pressure mm nace is increased sufficiently to overcome the weight of the valve, it is lifted from its seat by such pressure and the gas escapes. The escaping gas passes freely out through the space around the cone 12, but this 's ace is of such restricted character and .0 such shape that ore and coke or other solid material cannot follow the as, and the ieces-of such material will stri e against t e under side of the valve seat and be thrown back into the bleeder pipe. The outer surface'of the cone 12is preferabl provided with In 16, which are agrang to contact with t e valve-seating member 7, and therebyprev ti I v. tir'ely close the outlet through said .seat.
thereby substantiall increase of pressure within the To enable the .valve to be operated from the ground, any suitable arrangement of opdrawings.
The advanta es of.our invention will be apparent to those skilled in the art, since it provides a bleeder valve which will act freely and automatically to permit tlie'escape of gas from the furnace upon abnormal in;- crease of the pressure thereof, while at'the same time it effectually prevents the escape:
of ore and'coke. I
It will be obvious that other forms 'of valves maybe used having a guard attached. thereto, and that the guard itselfmay be otherwlse constructed and arranged within.
