Fig. '7 is-a side elevation of'part of the rolling r mill bed showing alternative means for maintaining the unit from movement in respect to 1 its normal position of mounting.

Referring to the drawingsyA indicates the unity as a whole which in the preferred form includes side members. The side members lll and l I may take any desirable form and as here shown are formed with enlarged portions l3 to receive 1 therethrough upper and lower connecting rods l4 and I5 respectively which .passthrou'g'h the a pair of side members In and Il designed to sup--; port side pressure rollers B which are rotatably.

mounted in suitable transverse slots l2 in the l zontally spaced apart opposed relation to one an other. This frame is suitably supported by means of standards C which passthrough the ends of the side members It and H and are secured on the upper side of thesemembers. by nuts I! and on the lower side by nuts l8, thereduced upper 3 Thus, by suitably manipulating nuts I] and I8 of 1 each standard, the side members liland H may end 19 of these standards. being screw-threaded.

be adjusted, upwardly or downwardly on these standards. Likewise, by adjusting the nuts [6 on" 1 the pairs of connecting rods I4 and I5, the side members I0 and II may be adjusted horizontally 1 inwardly or outwardly.

I preferably provide enlarged bores 20 the side members l0 and II forthe passage'of the connecting rods l4 and 15 so that by tightening the adjusting nuts on the rods Hi to a greater extent than those on the rods l5, the side 'members may be tilted so that theside pressure rollers B may incline downwardlytowards each othera By reversing this adjustment and tightening the nuts on the rods l5 to a greater extent than those I on the rods M, .the side pressure rollers maybe I caused to tilt upwardly and towards each other. In this connection it will be appreciated also that i the rolls B are independently.adjustable vertical enlarged bores 20 the side member ID may be disposed at a higher elevation than the side member and vice versa. As a whole, therefore, the simple unit is capable'of adjustment in various ways and in a simple manner.

In Figs. 2 to 5 the unit is shown disposed in position to cooperate with thehorizontally disposed pressure rollers '24 and 22 carried on the horizontal shafts 23 and which are journalled in the vertically extending bearing supports 25. These supports may be constructed in an extremely simple form merely including a slot 26 at their upper ends to carry the bearings 21 in vertically slidable relation controlled by suitable screws 28. Thus, to mount the unit A in association with the rollers 2| itis only necessary -'to remove the upper horizontal roller 2| and to cause the unit to straddle the lower roller 22 and shaft 24, the unit being supported readily by the standards C. The said pressure rollers Bare then disposed on each side of thehorizontal pressure rollers 2! and they. may-bedisposed forwardly or rearwardly of the rollers 2| and 22 or directly alongside of them merely byshifting the unit on the bed plate of the mill. I i

The unit is, of course, held from slidingmove-v ment along the bed plate of the machine in any 7 rection of its travel, a means of offsetting such tendency is necessary. This may beaccomplished in several ways. For instance, the. unit disclosed in Fig. 1 includes laterally projecting arms 29 projecting from the side members at one end thereof. These arms are designed to project be-' yond the sides of the verticalbearing supports.2.5..

Thus, by mountin in these projectingarms an adjusting screw 30, the end of which is designed to abut against one side of the bearing supports,

the unitA may be held from sliding movement. Moreover, it will be appreciated that the-adjusting screws 30 form a means of adjusting the unit relatively to the vrollers 2| and 22 so thatthe side pressure rollers B may be disposed in variouspositions as above referred to withrespect to the rolls 2| and 22.

This is a very important feature as it permits very fine adjustment of the side rolls to position them accurately to a fine degree in relation to the horizontal rolls, which fine adjustmentls necessary in various instances to overcomedefects in the rolling operation. I a i Instead of employing the bearing supports 25 as a means for preventing movement of the unit A, a separate means may be provided such as; in the case where the bearing supports mighti e widely spaced apart so as not-to be available for this purpose as above described; In this instance a retaining member 3| (see Fig. 6) may be pro: vided as shown. This includes a base plate 32- with spaced'apart upwardly. projecting posts: 33. The plate may be bolted or otherwise secured to the bed of the mill and the upwardly projecting posts cooperate with the adjusting screws 30 or the unitA in the same 'manner as the bearing on projecting bolts or the likeassociated, with the side members Ill and II." Inthis instance,

the projecting ends of bolts. H and I5 might be employed. The arms 34may be provided With'a hook-like extremity 36fdesigned to enter one-of the channels- 37 normally provided in the rolling mill 'bed and to engage one edge" thereof. The 5 arm 34 maybe suitably orificed 'as at 38 through which "the arms may be'adju'sted relatively of the unit. A thus providing for positioning" of the unit at various desired pointsirelativelyto the rolls carried by the bearing 81113130115125. Inaddition,"

a secondsetof arms 39may be'provided' extend ing generally in"'the'."opposite' direction to arms 34 "and entering into another channel 31 i of the. bed plate of the mill.. These arms might be ad:

justed similarly to the arms-34; Alternatively either the arms '34" or the arm's"39' maybe' em plo'yed: I

The 'unit provided by "the present invention may be used *with particular facility "to 'acco m-' plish various" operations and without the necessity of employing cumbersome adjusting'lstruc tures. The'sid'e pressurerolls are employed main ly in"'cooperationwith' the horizontally"disposed pressure'rolls which exert a vertically directed 7 pressure upon the'material'passing therebetween'. 2

It should 'be' noted, however, that the unit'does not always function with the horizontallyfldis posed. pressure rolls since in shaping metal to certaincontours it may be desirable to eliminate in certain units'actualuse of thehorizontal pres sure rolls and to substitute in cooperation'with the unit a mandrel or other device or devices cooperating with the side pressure" rolls for. producing thefinal desired shape.

The side pressure rollson the wholefunction to" effect a horizontally applied pressure or pressure directed at an angle'between the" horizontal and vertical, thus, cooperating in forming the material into a predetermined shape. This pressurem'ay' be exerted at a predetermined hori- 40' zontal plane having regard to the fact that the side members may be adjusted vertically, up-' wardlyor downwardly and such pressure -may also be'applied at predetermined similar or dif; ferent points. spaced apart horizontally, by,reason of the'adjustment of the sidelmembers to-. wards r and away from eachlother either inde pendently or together. Moreover, pressure may be applied in predetermined, differentlhorizontal 1 planes at the same .time. by. reason .of-Pthe fact that the side member ltl'may be'disposed at-a difierent level to the side'member I l'orvice versa, since each side member. is independently adjustable vertically. Finally, adjustment may be effected by way of the connecting rodsf l4 and l5'in such a way that the tightening nuts 16 on the rods I4 may be tightened to a degree greater than that on the rods [5 or vice versa, to cause the side memberstoincline downwardly other so. as to cause the sidepressure rollers B to exert a pressure atan angle between thehorizontal and vertical.

From the pointof view of adjustment it will be seenthat the unit providesfor diversified use in a simple'waybut apart from this it simplifies a number of problems in respect to the mountins of the side pressure rolls .aswill readily be appreciatech So'far astthe. bearingsupports 25- are concernedit is apparentthat the unit relieves may be 'constructe'd' economicallyto-withstandany appreciable strain: Furthermore; it will e appreciated that "the unit of-the present invert-=- tion provides for -a wide*-'degree-' ofadjustment"- is not possible" in' thei case-where the rolls are 'mount'ed as wasthe practice in the prior arts It is also apparent that the unit may beshifted from one position to anotheron the 'machine i n a verysimple-manner so that" it may be --operated at that -point=onthe machine where it is desired;- without it-beingwnecessary to provide special fit tings on the bearing supports:

While 1 the side pressure "rolls B are normally employedfo'r sidepressure operations it will be" appreciated thatinstead of these'rolls pressure shoes-"or guide members might be employed-.1 In the following claims, therefore; the term side pressure elements is employed which is designedto define rolls or otherpressure members that" might be employed;
