41 is a guide-wheel for the cable ll, which is attached to the carliago its lower end.

4! is a counterweight,connected to a rope or cable 43, which is attached to the frame of the carriage 5 for the purpose of returning it to its proper position after it has been raised or tilted to discharge [ht-buckets 1n the manner hereinafter tl(:-(!il)(tl.

44 IS stay connection for the rope or cable 43.

The operation is as follows: The table '26 is actuated to more a hauled bucket H into position to beengagcd by the book ll) of the carriage 5, which at the same time returns an empty bucket intoposition to recciveanother load. The engine is then operated to raise the carriage 5 by 'means of the cable 11 to the top of the furnace. The front end of the carriage strikes the stop projections 2" and the track of tho iunortrackrails 2", and continued pull on thocable 1 1 causes the carriage to turn on the axis of its front wheels as centers intothe position shown in dotted lines in Figf 1. This tilting movement of the carriage -lowers the chains 7 and bar 9 to bringthe buckctto rest upon tho top of the furnace in the manner sh'ownin dotted lines in- Fig. 3, the guide 46 being proyidedto properly center the bucket as it eofncs to rest. As soon 41s the bucket comes to rest upon the top of thefurnacethe continued slackingof the chains 7 lowers the bell 15 and discharges the stock upon the upper hell or gas seal 18. The weight of the" stock on this bell overcomes the action of the. counterweight 19, and the bell lowers and dischargesthestock into the hopper 21, upon the. lower bell-22-. The engine is now reversed, the counterweight 42 acts to. return the carriage 5 to; its normal position on the tracks 2, and the carriage descends to the base of the furnace v for another bucket.

The position of the buckets on the turn-table 26 is such as to bring the T-heads 17 of the rods 'l fi slightly above and forward of the hooks 10 when the carriage is in its lowered position, so that as the carriage, starts to rise the hooks will automaticallyengagc with the buckets.

The cotinterwelghted cable 43 may be connected directly to the frame of thecarriage 5; but in order to make it unnecessary for this cable to rise and fall with the carriage we prefer to provide tilting guides or receivers p the carriage 5 in 1 from the ltI})l( i may beloaded and ratsed to the top of the furnace and discharged-by a single "oporat ing 5 at"'a point near movement of the engine.

\farious changes may be made in the details of construction and arrangement of the several parts without departing from our in volition, since \Yhat we claim is v l The combination with a blast-Furnace havingan inclincdtrack leudingto itstop. of acarriage movable upon the track, said carriage having bucket engaging andosupport in; means, and means for tilting or raising the lower end of the carriage away from the track when it reaches the top of the furnace to thereby-loner its buckevsupporting portion: substantially as described. 7
