WORK SHIFTER Fl G. 6.

Patented July e9,` 1935 l UNITED STATES PATENT OFFICE Application February 25, 1935, Serial No. 8,148 In Great Britain September 14, 1933 Claims.

This invention relates to improvements in tilter devices for use in tilting metal billets and sections `to be rolled, being particularly applicable to devices for use in tilting and holding up 5 square or approximately square or diamondshaped billets when rolling in diamond passes. A tilter device comprising a cooperative pair of work-engaging headsconstructed in accordance with the present invention is illustrated in the accompanying drawings in which Fig. 1 is an end elevation, Fig.y 2 a plan view, Fig. 3 a longitudinal vertical section on the line w-a of Fig. 1, and Figs. 4-6 fragmentary views of vthe tilter heads. I y

The tilter device shown comprises a pair of tilter heads I, Ia constituted as iiuted conoidal members adapted for engagement in opposed relation with a metal billet 2 undergoing treatment ina rolling mill.

Each tilter head I or Ift is xed to or unitary with a toothed sector 3 mounted for partial rotation about its axis 4 in a link structure including a pair of links 5 mounted for pivotal movement about the axis I of a pinion 'I meshing with the sector 3 and with a pinion 8 on a shaft 9 carrying also a gear wheel I0 meshing with a pinion I I on the rotor shaft of a reversible electric driving motor I2. The axis 4 of the sector 3, the axis 6 of the pinion 1, the axis of the shaft 9 and the axis of the pinion II are all parallel to the line of travel of the billet through the mill.

The arrangement is such that each sector 3, as well as being rotatable about its own axis 4 by actuation of the respective electric motor I2, is free to move bodily in an arc about the axis 6 spaced from the axis 4 in accommodating itself to the movement of the billet 2.

Each tilter head I or Ia may be moved to an inoperative upper position as at A or an inoperative lower position as at B (Fig. 1).

Each tilter head assembly is incorporated in a frame structure I3` or I3a mounted upon the feed table of the rolling mill and movable trans-` versely of the line of travel of the billet 2. I4

45 denotes the roll housing of the rolling mill.

In operation, the tilter heads I and Ia are suitably angularly adjusted to tilt the billet in the required direction, one head being used as an l abutment and the other head being actuated to y tilt the billet, as shown in Figs. 4 and 5, in which 5 tion of the billet. Figs. 4 and 5 show the heads operating on a billet of comparatively large size, while Fig. 6 shows the heads operating on a billet of comparatively small size. As is understood, the sector 3 of the manipulating head la is iioatingly supported by the respective pair of 5 links 5 which thus permit the sector to adjust itself vertically as required in the co-operation of the head Ia with the billet 2.

I claim:-

1. In a metal rolling mill, a tilter device cornprising at least one movable tilter head, a toothed sector carrying said tilter head having its axis parallel with the direction of travel of the work, and a pinion meshing with said sector and having its axis parallel with and spaced from the axis of said sector, said sector being rotatable about its own axis, and movable bodily in an arc about the axis of said pinion.

2. In a metal rolling mill, a tilter device movable transversely of the direction of travel of the work, said device comprising a work-engaging head, a toothed sector carrying said head and rotatable about an axis parallel with the direction of travel of the work, a pinion meshing with said sector and having its axis parallel with and spaced from the axis of said sector, and a link structure mounted for pivotal movement about the axis of said pinion and carrying said sector.

3. In a metal rolling mill, a frame movable `transversely of the direction of travel of the work, 0 and a tilter device incorporated in said frame, said tilter device comprising a work-engaging head, a toothed sector carrying said head, and having its axis parallel with the direction `of travel of the work, a pinion meshing with said sector and journalled in said frame for rotation about an axis parallel with and spaced from the axis of said sector, and a structure mounted for pivotal movement about the axis of said pinion and carrying said sector.

4. In a metal rolling mill, a frame movable transversely of the direction of travel of the work, and a tilter device incorporated in said frame, said tilter device comprising a work-engaging head, a toothed sector carrying said head, and having its axis parallel with the direction of travel of the work, a pinion meshing with said sector and journalled in said frame for rotation about an axis parallel with and spaced from the axis of said sector, a structure mounted for pivotal movement about the axis of said pinion and carrying said `sector, a reversible motor mounted on said frame for rotation about an axis parallel to the axis of said sector, and a gear train connecting said motor with said pinion.

5. In a metal rolling mill, a tilter device movable transversely of the direction of travel of the work, said tilter device comprising a Work-engaging head, a toothed sector carrying said head,

5 and having its axis parallel with the direction of travel of the work, a pinion meshing with said sector and having its axis parallel with and spaced from the axis of said sector, links mounted for pivotal movement about the axis of said pinion and carrying said sector, a reversible motor rotatable about an axis parallel with the axis of said sector, and a gear train connecting said motor with said pinion.
