specicationfforming partpf tetta-s Patent, No. 1,900,51aied January 14', 41851,
I'o'dfll whom) t may/:concern:
Beit knownthatL'JQsEPH DORWART, 'of
Morgantown, -in the. county off Berks and Stateof Pennsylvania, have invented a new andl usefnl- Improvement in Blacksmiths "ll-uyeres, of which the following is a full, clear,
which the lblast irom` the bellows enters the44 chamber.` The windpi pe at its junction with thel'cha-inber curves upward tofcanse the airl to impinge more directly uponthe grate-bars,
and a curved partition is introduced within the chamber in' such manner that while itl assistsV inturnin g the blast upward it allows any vparticles* which may fall through the gratefbars to pass itl and lodge at the bottom 'ott-he chamber, where they cannot-obstruct the blast, and whence `they are removed "by withdrawing the sliding shut-ter. The lower extremity ct` this partit-ion extends below the' orifice of the wind-pipe., and its 'form is s uch that an eddy is formed at this point, which facilitates thedescent of cinders and thus pre-y vents theml from obstructing. the wind-pipe. i In the'accompanying drawings, AV is the uprightvessel forming the body of the tuyere;l
It contains kWithin ita chamber B, which isclosed athe' top 'by a grate C, which can be easily removed'and' replaced wheneyer it bef, comes necessary to perform these operi-ations;` or it may be shifted on its scatto' any posi- 'tioninost suitablefor heating articles o f 'p'e. culiar shape. .The bottomof this chamber ,is `closedbyasliding'plate D, whichl is easily wthdrawnfjfrom the tnyereltoallow any dirtI which may. lodge upon itjto. fall-out.
l f A lateral pipe E is cast fast'tothe body of y the tuyere; v This pipe at its junction 4with,
. the chamber B .is curved upwad, as represented in Fig. 2, to lead the blast more directly against thelower'face of the grate- C. {Immediately}v opposite the entrance of this pipe into the. chamberI `is the curved partition This vc'rossesthe chamber froin Vside to side, bnt'does not touch itatxthe upper and lower edges of the partitiomspacesct a being left at these points,`which allowany dirt wliichmay fall through the grate to passte the bottom of the chamber. tition byitsforin and position assists in'turning the blast upward, thus preventing the reverberationv that would take vplace if the blastiinpinged directly against thezsideof the chamber' opposite to that at which the pipe enters.` The blast being thus conducted to the upper partof the chamber distributes itself equally through thespaces in the grate,
and thusV produces a more equable combustion of the fuel, whileat the same time this partition not only permits the particles'vfail- .ing through the grate to Ypass'freelyto the bottomV of the chamber through thespaces left between the upperl and lower edges .of the partition and the` sides of the'chamben but Vprevents the stoppage ofthe orifice' of the 'wind-pipe by creating an eddy belowthe blastlpipe, which facilitates the-descent of cin'ders to the chamber beneath.
What I claim in the foregoing as my inven tlon,and desire to lsecure'by Letters Patent,
t The eut-veav partition inf the air-chamber -placed opposite the orifice of the wind-pipe, 'withits lower` 'edge' extendin g beneath this,
orifice,the arrangement and construction lof the partition being such that itservesthe double purpose of directing thebl'ast upward .and facilitating the descent of thecinders, as
