OuV opposite 'aides of the twoistnnds of rolls are conveyor tables 1.2 und 13, each com lbrisingrmseries of 'positively driven com reyer rolls 14 and 15 receiving their motion l'from the eountershafts 16 unrllf, connected with reversible motors, not shown, by which the direction of the rotation of the conveyor rolls may be changed at will. Upon eael'r Side of the Conveyor tables 12 und 13.?- are wheels 1r carrying fndloss belts 19 provided with lugs 29. The sprocket Wheels upon one sidegof the conveyor liable 12 are carried upon a coln'tershuiit 21, preil ublby drivenby un independent motor, und the sprocket wheels upon one side of the envoyer table 13 are Carried upon. a oountersl'luft 22, pref erablydriven by an independent motor.` l

The upper `or horirontz'rl` portions of the endless Chains 19 are carried upon tracks, one of which is' shown at 23, Fig. 2, :which maintain y-the lhorizontal portions 4`of the chain in ai plane just below'the supporting.

veyer rolls are the inclines 25 over which.

`the blooms are moved by the lugs 20; `The inelines 25V consist of triangular projections having vertical sides 26. l As the bloom reaches the apex or highest point of the ineline 25,` it falls upon the verticalside 26,v

pausing the bloom to be turned one quarter turn.

In operation, the initial'V rolling unido Vmi by the'pass 10 in the rolls 1, and is delivered upon the Vconveyer table 12. The bloom is then moved `sidevv'ise :icross the conveyor table 12 and over the inelines' 25,-causingit toxbe turned one quarter turn `and brought into ulinement with the pass 11 of the rolls 2'. The rotation of; the rolls in the'conveyer tables is then reversed and the bloom ce1'-y ried through the vass 11 und delivered .il on .the eonveyer tab e 1 3.V The bloom is t en transferred sidewise by means of the chains 19 and lugs 20 into allnement with the pass l' are rotated to carry the metal into position to be transferred by the belts 19 and lugs 20. The conveyor rolls are then stopped during the transfer and reversed to carry the metal into the next succeeding pass of the rolls 1 and 2.

The reduction of the bloom is eected by the alternate rolling of the metal between the rolls l and 2, the bloom being turned one quarter turn after each rolling. The

presentation of the bloom to and its delivery' from each pair of rolls and its sidewise transfer' from one pass to the next succeeding pass is done mechanically and with sufficient rapidity to prevent the undue loss of heat.

I claim,

1. A lrolling mill comprising two stands of two high rolls placed in staggered relation to each other, with the rolls of each stand provided with a multiplicity of passes for the consecutive-reduction of the rolled metal alternately in said stands, witha reduction in the size of the asses from corresponding ends of the rol s in each stand,

whereby a uniform lateralmovement will transfery the rolled metal from a pass in one vstand of rolls to the next consecutive ass in the other stand of rolls, conveyer ta les on opposite sides of said stands of rolls, common to al1 the asses in said rollsP means for rotating the ro ls in said stands 1n opposite directions, means for transferring the rolled metal by a sidewise movement from its aline- `ment wlth a pass inone stand ofrolls to an alinement'with a pass in the other stand of ro1ls,`a nde stationary incline having a vertical side interposed in the path ofthe sidewise movement of the rolled vmetalwhereby'the metal is rotatedl a predetermined partial revolution duringsaid sidewise movementi 2. A rolling mill comprisingtwo stands. of two high rolls placed in staggered relation to each other, with the ro 1s of said standsjournaled at one end in independent housin s and with the other and adjacent ends o the rolls journaled in a single integral housing.

3. A rolling mill comprising two stands of rolls running in opposite directions, with their passes out of alinement, means for transferrin the rolled, metal by a sidewise movement rom its alinement with a, pass in one stand of rolls to an alinement with a ass in the other stand of rolls, and means or rotating the rolled metal about its ow axis durin Dated t 1914.
