the retorts and on the hearth under the front ends of the retorts. This sample, or hlue-powder." contains a considerahle percentage of zinc which it is desin ahlc to save.

The process of smelting is progressive, hence the retorts of some sections must be cleaned out and re-charged while the smelting is progressing in the previously charged retorts in other sections; and in order to properly time the seve at stages ot' the operation and in order to economize in fuel, after the withd 'awal of the zinc; the cleaning out and re-charging of the retorts must he done quicklyand while all the retorts are very hot. i

The present apparatus is designed specially for ope 'ating on the hot retorts.

The apparatus as a whole comprises a movahle platform, a housing on the platform. a variety of tools supported in the housing and means for nmui 'uilatine the tools. The platform 1 is mounted on wheels :3 which travel on rails 3 parallel to the front of the furnace. The platform will he moved along the track to bring the housing in position innnerliately facing the seriesof retorts which are to he operated upon. The housing is a hos-shape metal structure, preferably covered with sheet iron plates. with asbestos hoard hetween the plates for insulation, and

There are four pairs of bumper heads eonnectt d with the til will slide on the cross hars Z5 and the. humper heads may move inwardly or out wardly with the 'arriage. When in position for operation the bumper heads are in aliuement with and center with respect to the retorts. The retorts are usually irrclined dmvnwardlv. Pivots 16 permit the inclination of the retorts. lccasionally there will he a dilference between the centers of the tiers of retorts, the. hinged cross pieces 12 admit of adjusting, the width between the uprights 10 to correspond. to the width hetween the centers of the tiers of r'etorts. Horizontal so a per blades 19 extend substantially the entire width of the tool support and are equipped with forked handles 20 which support the scrapers in a horizontal position on the cross pieces 5 respectively. The handles 2U extend ran'waidl' and are used to slide the scrapers forwardly and rearwardlv. The scrapers may he operated imlepcndentl of each other.

The apparatus comprises two of blow-out" pipes. Each set comprises a vertical pipe 21. h rizontal pipes 2:! in cone. munication with the pipe it an intake 23 and a handle. 2- a horizontal position on the housii A valve :29 controls admission of vat-r or steam to the header 26.
