INGO'r-PUSHING ruimenv Application nled July 23,

l' My invention relates to mechanismioringot pushing devices used for introducing in- Frequently, the space 4available on the sidev of the furnace where the ingots are introduced, is not large `ments used for this fkindaof Vwork to `push enough to permit the aelethe ingots far enough into the furnace. In that case, it becomesfnecessary'to use ,telescoping elements adapted'tofbe extended 'and shortened. Byj-means of such telescoping elements which arefirst coupled at one end, the ingots can be pushed into the furnace to a certain depth, but then'it becomes necessary yto loosen the coupling, to pull the `elements apart backwards to again couple them at the other end and `then push the ingots by means of the kpushing head to `the desired depth into the furnace.v The'same-operation,

in the reverse order, must then be repeate upon the withdrawal :of rthe pushing `head from the furnaceconsuming much time,.dur

ing which time,the elements, as they lie idle in the 4furnace become'very hot, According to the present invention, auxiliary' 'screwspindles are provided, in addition to the main screw-spindle, said auxiliary spindles carrying the pushing head adapted to act von the ingots and being so arranged that the ingots caribe quickly and securely pushed into vthe reheating furnace to any desired de th, so that the elements .used'or the intro notion of the ingots will not be exposed to the hot combustion gases of the furnace `any longer than is required fo'r pushing 'theingots in.

In the drawing, in which I havelshown, by way of illustration, an embodiment of :the invention, Y

' Fig. 1 shows the new device ready to push ingots into a reheating furnace', parts being showl .in section, while Fig. 2 show s'the same advanced position.

3, and the same is the case, as the spindles 8 are withdrawn from their advanced position. In this manner, the introduction of the ingots into the furnace and the Withdrawal of ushing head 13 are effected much more rapidly than with the telescopic mechanism heretofore used, and the various elements will not 'lie idle for any length of time and be exposed to the heat of the hot combustion gases. e

I claim: 1

l. In an ingot pushing device, the combination with the frame, a main operating spindle journalled therein and the pushing head,

of a movablepart adaptedto be moved back and forth along said frame by said main s indle, auxiliary spindles rotatably journa ed in said -movable part, and means in said frame operableby said main spindle'for operation said auxiliary spindlesv to thereby advance and retract said -pushing head.

2. In an ingot pushing device, the combination with the frame, of a main operating spindle journalled therein and the `pushing,

head, of a movable cross-beam adapted to be moved back and forthalong said frame by said'main s indle, auxiliary spindles rotatably journa ed in'said movable cross-beam,

means in said frame operableby said main spindle for operating said auxiliary spindles,

and lmeans actuated by said auxiliaiy spindles so as to advance and retract sai pushing head.

vv3. In an ingot pushin l device, the-combi@ nation with the frame, o amainscrew-spindle journalled therein and the pushing head of a movable cross-beam adapted to be moved back and forth along said frame by said main screw-spindle, auxiliary Yscrew-spindles irotatably journalled in said Ymovable crossbeam, toothed wheels at the' inner ends of said auxiliary screw-spindles, a toothed wheel on said main screw-spindle adapted to rotate therewith and in mesh with Vsaid toothed p wheels, means for rotating said mainl screwf spindle ineither direction, and extension ele`- ments 'actuated by said auxiliary screW-spin dless'f as toadvance and retract said pusl 1n head. i Y
