The holders for t e'guide rollerseach comprises a flatspring member 2 having a bearing; sleeve 2d welded to ;,qn e end anda roller head t eld d, to the o er he ear sleeves fit over shafts 2a that are welded to the casing I, and the holders are retained on the shafts by screws that are threaded into the shafts and seat on washers 2b. ,Shield plates Publio l aw 630; August 8, 13451 eiz ruarr 1 196 2e are preferably mounted between the sleeve 2d 2 and the roller head 3 of; eachholder, and'epacedv from the springs}, toproteet the latter from heat radiation the hot rolling of bars and rods. The guide rollers are mounted on the roller heads, 3 by ball bearings 5 and shafts 6. A pair of screws 54 are threaded into wall; Portions is at each side of the casing I to adjust the spacing of they rollers. t to the size of thebars, or other stock to be rolled.

The thickness or the flat spring members- 2 will depend uponthe material to be handled and other design requirements in particular cases, the'essential conditions contemplated by theinvention being that the roller holders are resilient and'are mounted on the casing I forangular or rocking movement, and that the screws l4 apply-- pressure to the intermediate section of the resilient holders to adjust the normal spacing of the rollers 4' and to insure adequate pressure of" the rollers 4' upon the Work piece. As" indicated graphically in Fig. 7', the resilient holders provide an automatic adjustment, of the spacing of; the rollers 4 to meet different operating conditions such as; for ex ample, that; of a square rod or work piece I! that should; run flat through rolls H (indicated by arcua le, lines l1, Fig; 2) but; that-- approaches the rollers 4 on the diagonal. The spring members; yield tov permit the movement of; the bar into the rollers 4* and; the resultant high pressure exerted'on the bar I8 by-t'he rollers 4' will quickly effecta partial rotation of the work piece l8 into a stable position with opposite-sides flat against the rollers 4'. Y

The rollers 4 of the embodiment shown in 2' Figs. 1 3 are cylindrical; and this form. of; the

invention is adapted for use with flat-,or approx mete r a tee ha h opp d: P a e su faces Guide boxes and/or the verticallyarran ed s t f: olle s t e Q-Qa Q uni sal tellin m ll are. e imin ed; x h resi ient mounting of the rollers 4' on the, holders that ihsz u he, lat shrine memb s It; is to be, noted that the described construe;-

In the embodiment illustrated in- Flgfit, '1: ta- 6, t e ca ng is if ec ushler r mef r as viewed in cross-section, and a, guide box- 8' is mounted within the casing between filler blocks 9, Hi that are pressed toward each other by screws [3. The lower block I0 is secured to the casing I by screws Illa, and both blocks have side flanges 8a that insure the desired lateral positioning of the guide box. Forward movement of the guide box is prevented by a lug or stop II that may be an integral part of the casing l The fiat springs 2 are arranged between the guide box 8 and the side walls of the casing I, the

springs being supported on a rocker H! to which they are clamped by pressure screws l that are threaded through the upper wall of the casing. Each spring 2 has rounded bearing projections a at its upper and lower edges that are drawn into engagement with the casing walls by an anchoring screw it. The rocker I2 is well in advance of the screws IS on which the springs 2 pivot when the roller heads 3 are vertically adjusted with respect to each other by means of the screws ii. The roller heads 3 and rollers 4 are adjusted towards each other by screws I 4 that are cated between the rounded bearings a of the springs and the roller heads 3. The anchor screws IE are located adjacent the bearings a and at the side thereof towards the adjusting screws l4, whereby the roller holders are held apart by tightening the screws I'B. This moun ing is particularly advantageous in high speed rolling as it prevents the rollers from swinging into the path of the material being rolled. As

that the points of attachment and the points of adjustment of the roller holders are reversed. In

theFi-gs. 4 to 6 construction, the ends of the springs 2 are supported on the casing for rocking movement on the bearing projections a and for angular adjustment about the axes of the associated elements are substantially the same as Y previously described, but the rocker l2 and vertical adjusting screws l5 are at the entrance end .of. the casing I, and the anchor screws 15 extend through the casing I at the advance points to draw the springs 2 down upon the rounded bearing projections, i. e. support screws Ilia mounted in the Wallsv of the casing I, after the rollers 4 have been adjusted as desired by screws 14 that extend through the springs 2 to seat upon the guide box 8.

1 Itis to be noted that the guide box 8 shields the springs 2 from radiation when rolling hot barsand rods, thus making it unnecessary to pro vide separate shield members similar to the shield plates 2e of Fig. 1. r The invention is not limited to the use of but two guide rollers or to the particular constructions. herein shown and described as various 1. Bar stock guiding mechanism for rolling 4 mills comprising a supporting base, a pair of resilient members one at each side of the path for the bar, a guide anti-friction roller carried by the free outer end portion of each of said members the periphery of the roller ahead of the rolling mill reaching outside said end'portion which constitutes a roller head integral with the resilient member, means mounting said members on said base for angular adjustment independent of each other about axes parallel to the axes of said rollers, and adjusting screws engaging said resilient members at points spaced from said mounting means to determine the normal spacing of said rollers from each other.

2..Guiding mechanism as recited in claim 1, wherein said mounting means comprises shafts secured to said supporting base and bearing sleeves welded to said resilient members.

I 3. Guiding mechanism as recited in claim 1, wherein said supporting base comprises a casing having side walls; and said mounting means comprises rounded bearing projections on said resilient members, and anchor screws for drawing said resilient members towards the respective side walls to seat said bearing projections thereon. 4. Guiding means for rolling mills comprising a pair of guide rollers, fiat spring members car rying said rollers in roller heads constituting parts of the resilient members, the peripheries of the rollers ahead of the rolling mill reaching outside the roller heads, a casing within which said spring members are positioned, bearing projections supporting said spring members rocking about axes parallel to the axesof said rollers, adjusting screws engaging said spring-members at points spaced from said bearing projections to rock said spring members to determine the normal spacing of said rollers, and anchor screws drawing said spring members into engagement with said adjusting screws. 7

5. Guiding means as recited. in claim 4, wherein said bearing projections are on said spring members.

6. Guiding means as recited in claim 4, wherein said bearing projections. are at the entrance end of said spring members, and said adjusting screws engage'inte'rmediate points on said spring members.

7. Bar stock guiding mechanism as defined in claim 1 and which further includes a heat shield interposed between each of saidv resilient members and the bar stock when passed through the mechanism. 7 I
