To azz hat@ it mtg/105mm:

Beit known that I, woorsat Meri. 'JOHN- State of Connecticut, have invented .certain `g'ic'al Condensers, of which the following is a specification. This v'invention relates broadly to an apparatus for condensing metallic vapors, ut

more vspecifically 'itconcerns improved appa# ratus for condensing zinc vapors, in 'accorde ance with myprocess described and claimed in a co ending application, Serial No. 4119,86 1,

iiled anuary,1908.

' One'object-of this inventionv is to provide simple' andinexpensive apparatus for 'con'- I' l densing metallic vapors andl particularlyr condensingvapors', ofzinc, which will operate at a very high degree ot`.elicien'cyd other objtctsand-advttnttges will lbe in Ipart obvious from the annexed drawings and 1n part pointed out thefollowing .descripclaims.

tion.. This invention accordingly consists in the y ieaturesof construction, combinations of, elements and arrangement. ofv parts .which"will be'exemplied in the construction hereinaf-` ter set forth, andthe scope of the 'ap lication' of which` will beindicated in the. ollowing Figure 1 is a central sectional elevationof a' condenser representing OneembOdiment of 'm'yfinventiom and Fig. 2 is a transverse sectional elevation of the same taken in the veri tical plane of'lineZ-"f-l of Fig. 1.-

This apparatus may be utilized to carryout As `shownin the accompanying drawings,

. the condensing chamber 1 may be constructedfin suitable size and shape of anydesired material, as' themasonryr 2,- and preferably, though not necessarily, maybe provided in or adjacent its lower en d' with a metallic colmeans 'of aue .4' leading into the upper partA 'of said: chamber.' Thel residu al vapors; and

fixed gases areena'bled. to escape through the outlet-5, van'dfor the purpose oi collecting any In the -accompanying'ndrawmgs, like char-' l derlie the collecting basin 3..

iixed gases maybe 1n communication with` theoutlet5.^ To .the en'd that the apparatus"andy collectingbasin may-be initially'heated, or maintained 'at a suitable temperature,gaS burners 8 or other available form offurnace may-un-- I For the purpose of disposing the melted metal within the condensing chamber so that' a relatively large superficial area may be `presented to the incoming metallic vapors, I

may provide -one or more receptacles which;

preferably assume the form and functionaof the ilue's designated by 11. may be conveniently shaped in crosssection in the form 'of a hollowrectangle provided, Y'with upwardly' extending marginal ribsf12,

or otherwise recessedor constructed -to rfre- 'ceive and retainin the form' of a shallowpool or ilm quantities 'of 'molten metal;

These iiues 1 1 i A furtherA feature yof' advantage which f -have adopted in this apparatus resides 4in so arranging the ues or shelves as the case may be that'the metal mayoverloW-and shower from one uetotheother, thereby providing la'diiferent butyet elicientexposure of the f molten' metal to the metallic vapors. To thisl end,` the transverseflues 11,;are prefer-l ably staggered in the .manner indicated $0 that theincoming gases! may be not only brought into intimate contact with the relatively quiescent surface'in the receptacles,

but will also-.be'compelled tozthorouglilyim iiitrate 'through the shower of,rnolte n zinc.

In o rder thatthe metal flowing over and showering iromonerece' tacle to another,

-may be maintained wit in definite and 'somewhat restrictedlimits of temperature, `I

have provided flues 9 and 1Q for heated'fgascs.

lor other liuids within or adjacentfopposite sides of tli'econden'sing chamber andcommunicating withthetransverse-flues 1 1.

.To the end that an artiiicial 'circulation of densing chamber'feitlier duringI the initial stages of4 the process or duringthe normall workings thereof', as the case may be, I provide means for introducing molten metal to the uppermost, and if desired to intermediary iiues, Aand likewise, I provide means for .withdrawing the molten metal -from other ilues or from thecollecting basin. Thus, as shown on the drawings, the uppermost flue or lue's 11 may be extended beyond one of 4molten lmetal' 'maybe maintained in the conblue powder oro'tliervaluablc constituents, a the condenser walls v:1s-shown at 14 in such different levels-,
