shaped by collars on the horizontal rolls'. This rolleonstrnetion enables any fins formed on the edges of the langes to be' rolled down loy reversing the bar, or ro` Y rating it through an angle of 18.0, between successive passes through the rolls, as fully sel. 'forth in my prior application, Ser. No. 355,380, 'iledu June 2, 1908. Each vertical roll is supporled and adjusted by a chock8 which 'slides horizontally in guideways 9 .machined in brackets 10 cast integral with-65 and projecting outward from a housing l. 5.

Means are provided for simultaneously adjusting the horizontal rolls, and also, preferably, the Vertical rolls, so as to accuialcly niainlain the shape of the pass. Various mechanismsmay be used to eiliect this simulhineons adjustment. That shown eoinf prises vertical screws l1 which pass through nuls fixed in the upper and lower closed einlioi elle housings 1., and bear against the journal-boxes 3. A bevel-gear 12 ,uis keyed on the onier end of each screw, the@ gears engaging complementary gears 1b keyed on upper and lower horizonlal shafls 1 lll. Alined sprockets 15- connected by ijn 80. ohain- 'lll are alsokoyed on these shaftgso that they rotate in unison, thereby causing the simultaneous and equal inward movement or' the horizontal rolls. Pairsof horizontal screws 1T are threaded Athrfmgh'cross 85 plates 10 which are bolted to the outer, ends of the brackcls 10. 'These horizontal .screws also carry Sprockets 18 and are preferably rol'n'ted in unison with tlierertical screws 11, die sprockel's 18 at the Aright engaging'Q che chain 1G while those at the left engage a chain 19 which is driven loy a sprocket 2O on the upper shaft lfl. The screws 17 bear againsttbe onler ends oi the chooks 8- and thereby force the vertical rolls inward simultaiiconsly willi the horizontal rolls, through a dislance which predetermined by the pitch of the screws., so as to maintain the exact shape ol the pass The distance between the housings 1 may be adjusted lo sull di'llcrenl rolls by moans ofthe ric-bolts 2l whichconnecll the cr0ss- 4 plates l0. v

Suitable guides for the blank' may be' allached to the bolts 21 and tothe honsings.
