This perl'orated plate is preferably cast integral with the elbow Fig. 2.

The charging chamber or gun S is adapted to contain a little more ore than is necessary to fill one of the retorts 2 and for the purpose of controlling the passage of ore through said chamber 1 preferably provide a-cut oil valve plate 28 in the form of a slide arranged in guide recesses 29 in the upper end of the elbow 14. The outer end 01' the valve plate or slide 28 projects outside of the elbow and opening 30 so that it may be readily moved into or out 01' the chamber to close or open the lowerend of the vertical section or pipe 13.

In operation, the main carriage 3 is first adjusted in front of one or the vertical series of retort-s in the furnace and the SUPPlGlIlGIl- 'tal carriage 7 is moved inwardly to dispose the nozzle 15 of the charging chamber or gun within one of the retort. The valve plate 28 is then pulled outwardly to release the ore in the hopper and the lever 27 of the injector or blast valve is then operated to open the latter so that the blast of air will force the ore'through the nozzle 15 and into the re- Al'ter one retort is filled, the charging chamber is adjusted vertically to illl another and this operation is again repeated to fill the third. When the nozzle 15 projects into one of the retorts it is necessary to shift the 14, as clearly shown in carriage 7 to move the nozzle out of the re tort each time the charging chamber is adjusted. After the retorts of one vertical series have been. filled, the'rnain carriage 3 is shifted to the next series tobe filled.

From the foregoing it will be seen that the use of my invention will ell'ect a reat saving in labor, since two men may QllOCLlVGlY operate it and fill the rct-orts in a much shorter time than is required for filling them manually by a larger number 01' men. This saving in time e'll'ects an increase in the output or )roduction ol the furnace and the saving of abor lessensthe cost 01 operating the same Furthermore, the use of my improved apparatus enables the ore to be con veyed to the hoppers from the roasters or beds-by means 01' pan conveyors, thereby reducin" the expense of o crating the [urnace. t will be noted aso that my im proved apparatus is simple in construction so that it may be produced and installed at 1 track,

The charging chamber or gun has its chains 18 connected to a ring which engages 17 so that the charging chamber or gun may be removed from the supplemental carriage 7 and a pair of tongs or other grappling device may be substituted for it so that broken or damagcd retorts may be easily removed from the fur-j l l l 1 nace and replaced by new onesl Having thus described my invention what I claim is:

1. The combination of an elevated track, a

main carriage upon the same, a supplemental z carriage upon the main carriage and movable in a plane at right angles to said elevated track, a charging chamber of right an 'ular form having an elbow united by vertica and horizontal sections, forming a discharge nozzle and the vertical section having a hopper at its upper end, an injector arrange in the elbow, a valve for said injector, a flexible blast sup ly pipe connected to the injector, a controll the charging chamber above its elbow, a chute upon the main carriage to discharge into said hopper and means for suspending the charging chamber from the supplementa carriage and adjusting it vertically.

2. The combination of an elevated track, a main carriage upon the same, a sup lemental carriage upon the main carriage an movable r in a plane at right angles to said elevated track, a chargim chamber form having an elbow united by vertica and horizontal sections, the horizontal section forming a discharge nozzle and the vertical section having a hopper at its upper end, an injector arranged in the elbow, a valve for 1 said injector, a flexible blast sup ly pipe con nected to the injector, a control ing valve in the charging chamber above its elbow, a chute upon the main carriage to discharge into said hop er, a chain hoist depending 1 from the supp emental carriage'and flexible connections between the chain hoist and the charging chamber.

3. The combination of an elevated track, a main carriage upon the same, a sup lernental carriage upon the main carriage an movable in. a plane at right angles to said elevated track, a charging chamber of right angulan form having a horizontal section forming a discharge nozzle and a verticalsection provided with a be per, a chute u on the main carriage to disc large into sai hop er and means for suspending the charging c amber from the sup lemental carriage and adjusting it vertica y..

4. The combination of an elevated track, a main carriage upon the same, a sup lemental carriage upon the main carriage an movable in a plane at right angles to said elevated a charging chamber of right angular the horizontal section 5 ing valvein 9( of right an ular 1 plane at ri form having a horizontal section forming e discharge nozzle and a vertical section provided with a hopper, a controlling valve in the vertical section of said chamber, an inj ector in the angular portion of said chamber, and means for suspending said charging chamber from the su plementel carriage and ad'usting it vertically.

5. T e combination of s main structure, a main supply chute in the upper ortion thereof, a controlling valve for said 0 ute, e horizontally disposed elevated track in said structure, a main carriage to travel on said track and beneath said chute, a supplemental carriage to travel on the main carriage in e, ht angles to said elevated track, a ember suspended from the sup charging c 'plementel carria e and a chute upon the main carriage and adapted to direct the dis- -charge from said supply chute into said charging chamber.

6. The combination of e chm-gin chamber having vertical and horizonte sections united by an elbow, the horizontal section forming a discharge nozzle and theverticel section having a hopper at its up er end and a controlling valve in the vertice section of said charging chamber.

7. The combination of a charging chamber having vertical and horizontal sections united by an elbow, the horizontal section forming at discharge nozzle and the vertical section having 11 hopper at its u per end, a controlling valve in the vcrtico section of said charging chamber and en. injector srranged in said elbow.
