These tulies are to be filled with carbon, as shewn. At those en ds of the t bes which are farthest from the resisto r is a, vertical space, or filter-chamber, T, the lsettezn of which, 10, serves as a zinc reservoir from which collected metal may, in various suitable manners, be ccntimmusly or intermittently withdrawn. The chanil:er,T, is intended to he more or less filled with carhcn, serying as final filter for the upwardly escaping gases, and manifestly any zinc ce dense il' therein will gi'svitzite to the reservoir. The carbon the condensing tubes is preferably packed se as to be in physical contact with the resistor-1351113011 and that ce tziined in. the filter chamber. liaising normal operm ties, the hemperstur'e of the carbon in the tubes pregressiveiy diminishes from the resister tethe filter chamber, and the rate of radiation therefrom may be augmented or diminished by remeving c2 appl' ieg hlahle sting materiel, as V, is the opeh s s 2, erga' VJ, above the tubes, hi by'heafting or cooling '22 fine, as Y, fez-med in. that portion 9;? the furnace'iiall which. is opposite Q7. adjacent te the outlet ends of the laibes. 1: 1 tithes erds, if for instehcethe fine Y is heehed, as by 'means 5; ass or electrically from a sesistoi', this will impart heat t0 the filter-carbon and thence to the carbon in the condensing tubes; it clear thetthe difference at temperz'it 'e be;

maintained by applying a heating or cooling medium to the interior of the line Y when required. The temperature between the resistor last referred to and the filter chamber so as to be able to utilize the iiltercarbon as a direct resistor whereby the interior of the filter can be heated as desired.

When the reaction is in progress, the developed fume and gas, or gases, must pass directly through the hot resistor in horizontal planes, thence entering and traversing the several condenser-tubes wherein the liquated fume gravitates to the trough or receptacle at the bottoni of the filter chamber T, in the manner denoted by arrow 12, and the residual gases flow upwardly, as denoted by the arrow'13, through the filter chamber and finally out to the atmosphere. The freedom of gas-flow through the filtering carbon, and the volume or intensity of the flame if burned to (10,, may be conveniently controlled by a damper or, slidable bricks, as 14.

The conditipns and construction here described and illustrated are favorable for realizing a, rapid and uniform rate of reaction and high efiiciency in the condensation of fume to liquid metal. Moreover, such a type of combined furnace and condenser is easy and inexpensive to build, and the cost of maintenance is of nominal amount.

The invention is not to be limited by the precise lines of the drawings, as various detail modifications may be made in the design without departing from the spirit and essence thereof.

We claim as our invention:

1. in an electric zinc furnace a longitudinally extending bed of carbon resistor,

a charging pocket or pockets disposed along one of thevertical sides of said resistor, a plurality of transversely disposed tubes, filled with carbon which are arranged along the other vertical. side of said resistor and a space or chamber with which'the said tubes communicate.

2. In an electric zinc furnace a bed of carbon resistor along one of whose vertical sides the reaction takes place, and a system of condensing tubes arranged along the other vertical face of said resistor, all of the vol-utilized products of the reaction being thereby caused to first pass through the interstices of said resistor and thence directly to and intothe condensing tubes.

3. In an electric zinc furnace, the combination with a longitudinally extending bed of carbon resistor and a filter chamberparallel thereto, of a plurality of trans versely extending interposed connecting condenser tubes.

4. In an electric zinc furnace, the coin bination with a bed of carbon resistor and a parallel filter chamber, of a plurality of interposed connecting condenser tubesiilled with carbon which is in physical contact with the carbon in the resistor and the filter carbon.

5.- An electric zinc furnace having a plurality of condenser tubes leading from a bed of carbon resistor to the interior of a filter chamber, and provided with an open space or gap above the said tubes from whence the rate of heat-radiation may be regulated or controlled.

6. In an electric zinc furnace a bed of carbon resistor, a filter chamber provided therein with filter carbon, a plurality of carbon-filledcondenser tubes for receiving the fume from the carbon resistor, said tubes communicating with the interior of the filter chambers and means for heating or cooling the carbon contained in said filter chamber.

7. In a combined zinc furnace and condenser a longitudinally extending reaction chamber provided therein with a resistor, a series of transversely extending condensing tubes and a longitudinally extending filter chamber, the condenser tubes be ing interposed between the resistor and the filter, said resistor being formed of broken carbon, the filter chamber being provided therein with broken carbon and the condenser tubes being filled with carbon which contacts at one end of each of the tubes with the resistor carbon and at the other end of each of the tubes with the filter carbon.

8. In a combined zinc furnace and condenser a longitudinally extending carbon resistor, a longitudinally extending carbon filter medium, and interposed therebetween a series of transversely extending connecting condensing tubes provided therein with carbon.

9. In a zinc furnace a longitudinally extending resistor arranged so as to receive along one face thereof the charge, there being located at the opposite face thereof a system of condensing tubes which is filled with broken carbon which contacts with the resistor and also with the broken carbon in a filter chamber of the furnace whereby the gaseous 'products' of the reaction pass through the resistor, the metallic fumes being principally condensed to liquid zinc ,jnthe system of condensing tubes and the residual products passing. from the condensing system through the carbon in the filter prior to escaping to the atmosphere.

.10. A furnace having a longitudinally. ex-

tending carbon resistor in a reaction chai'nber,

a longitudinally extending filter chamber, a

series of transversely extending coniensing; tubes leading from the resistor to the interior of the filter chamber and means 1r;- euted adjacent 0 the ends of the condenser iubes for conrolling the chamber temperw ture, the condenser tubes and the filter chamber being provided with carbon.
