14 Claims.

My invention consists of an improvement in renewable guides for rolling mills, adapted to receive the rolled blank, bar, strip or other form directly from the re tion and support.

In the rolling mill art, it is desirable to provide means ensuring direct outward pass of the rolled article from 11 pass, for subsequent directhe bite of the rolls and to ensure its continuous delivery therefrom in its outward travel. in connection with This is particularly important the initial emergenceof the article from the rolls, when there is any tendency to adhere to or follow the contour of either roll. Ordinarily, this is done with one or a pair of tapering terminals forming the inner end or ends of outwardly extending supporting guides usually made of steel, and frequently provided with rollers or balls on the upper surface of the lower member.

Due to the fact that the inner tapering termie nals bear against the roll faces and into the nip of the rolls, and of wear very rapidly, placed.

In my invention the high temperature, these and must befrequently re- I provide an inner terminal The latter is also so constructed and mounted as to provide for longitudinal adjustment to take up wear on the terminal when desired, and is also provided with means for easily connecting and disconnecting the members, as hereinafter described.

Referring to the ferred construction:

Fig. 5 is a partial horizontal sectional view on the line V--V of Fig. 1;

Fig. 6 is a perspective view of one of the point members, detached;

Fig. '7 is a plan view showing a modified construction.

Referring to the drawing, 2, 2, are the rolls of a mill, having the usual adjustments etc, as in standard practice.

Mounted on any suitable base 3, which may be a cross bar between the mill housings, is a supporting plate or bar 4 on the inner end portion of which is the roll-engaging guide point terminal 5.

Said terminal is rounded on its roll-engaging 5 side, as at 6, and terminates in a narrow knifelike edge 1 adapted to lie in the lower or upper plane of the roll pass, i.-e., tangent to theroll periphery. l I.

As hus' made, the pressure of the rolled bar in emerging from the pass of the rolls is against the opposing or supporting face of the point and its plate By reason of the connection between the plate and point, as hereinafter described, such pressure tends to tighten the joint, ratherthan loosen or disconnect it.

Supporting plate 4 is mounted by its outer terminal 8 on bar 3 and preferably has a supporting shoulder or abutment 9, for longitudinal adjustment. Between shoulder 9 and'bar 3 may be 20 interposed suitable adjusting devices, as liners l i. As the plate and its inner contact or point mem-' ber 5 are adjusted inwardly, the rapid'wear of the latter may be compensated for until it is worn out. r v

Member 5 and plate 4 are rigidly connected by means of an interlocking shank l2 and a dovetail or key head i3 engaging a corresponding receiving socket in plate 4. Shank i2 is of reduced width, extending rearwardly of the main terminal head 5, which abuts against the' end of plate 4 by its laterally extending faces I4.

Shank l2 is tapered downwardly at each side, as at 15, while the faces !4 of the head 5 and inner shoulder faces Iii of head [3 taper downwardly and outwardly in opposite directions. The opposite side faces We and rear face I3b of head l3 taper or converge downwardly and inwardly. The receiving socket therefor offplate 4 is of a corresponding contour, as in Fig. 2, having inwardly extending interlocking abutments H for shouldered engagement with faces l4 and [6 of point 5 and key head l3 respectively. p I

The inner faces of abutments H and the several receiving faces of the socket are correspondingly 45 and conformably tapered, so that when the terminal 5 is placed imposition, it has a tapering fit snug and tight between the several embracing and wedging faces. By such arrangement the point member 5 makes a binding fit in the socket and is easily removed. a c r .i

Such tapered conformation of the interfitting faces not only facilitate easy placement and re- 1mova1 of the point 5 inthe socketof plate .4, but

also effect flush continuation of the blank-engaging faces of both.

I also provide means for retaining the active terminal 5 in such interlocked wedged-in position, adapted to permit separation and removal. One such means consists of a pair of springs l8, one at each side of plate 4, preferably lying flush in shouldered grooves l9, secured by a screw or bolt 20.

Said springs extend along beyond the end of the plate and into similar shouldered grooves ll of the terminal 5, as shown.

When thus .in position, the plate and bar are fixedly held against separation, until the springs are retracted. For the purpose of easy retraction of the springs, the plate is provided with concaved clearance openings 22 for insertion of a pin or other outwardly springing pressure to disengage the spring terminals from the point 5.

When the springs are thus released, the point arrangement, forming a substantial duplicate of ,the construction above described. In such case a similar bar 3a or its equivalentmay be used, and the plate 4a and point 5a are held upwardly against it and the roll by any suitable means, as

supports25a. f V v By use of the double application, below and above the pass zone of the rolls, any tendency of the rolled blank to varyfrom its desired outward path is positively prevented. It will also be understood that vertical lateral guides of any suitable form may be located, one at each side of the plate and its point or tip, as practiced in the use of the ordinary one piece horizontal guide or guides. I r o V It'will also be understood that the transverse downwardly and inwardly tapered socket at the front-end of bar 4 for reception of shank l2, and its head l3 may extend entirely through the bar as shown, or only part way, as. desired.

The especial advantage of the invention is the economy and better results arising; from the ease and'cheapness of the renewableterminal point 5. While the plate 4 may be madeof steel or other suitable metal, it is not subject to the rapid wear and deterioration of theroll-engaging end or ends. These are preferably of cast iron, do not require machining or finishing, and have the necessary limited resistance to wear and abrasion.

The construction provides for very accurate and rigid placementof the point in its holder, with a plurality of contacting faces in varying planes,

and insertion and removal towards and from the I general'plane of the base '4.

By adjusting the plate 4, such wear is compen sated for from time tov time, and when used to its limit ofpmaterial, a. new tip or point mayjbe subcost and with little delay or in- No. 719,702. I r
