I MANIPULATOB FOR ROLLING IIIILLS.
Applicationfiled January 16, 1322. Serial No. 529,518.
To all whom it may concern:
Be it known that I. WILLIAM L. Drrons, residing at Pittsburgh, 1n the county of Allegheny and State of Pennsylvania, a
citizen of the United States have invent ed or discovered certain new and useful Improvements in Manipulators for Rolling Mills, of which improvements the following is a specification.
The invention described herein relates to certain improvements in manipulators for rolling mills and has for its object the provision of means whereby the piece being rolled may be turned through an arc of 180 degrees the improvements being especially adapted for turning a slab or piece having a width substantially greater than its thickness. The invention is hereinafter more fully described and claimed. 1
In the accompanying drawing forminga part of this specification, Fig. 1 is a top plan view of a portion of a feed table hav ing the improved manipulator combined therewith, and Figs. 2, 3 and 4 are sectional elevations of the same showing respectively different positions to which the parts are moved in turning a slab; Figures 5 and 6 are views similar to-Figs. 2, 3 and 4, but. illustrating a modification in the manner of operating the manipulator.
The improvement claimed herein can be combined with any suitable construction of feed table known in the art. In the practice of the invention the reciprocating member of the manipulator consists of a head secured to a longitudinally movable supporting and guiding member 2 mounted in earings 3 in a frame 4 arranged at one side of the feed table. The head which is arranged at right angles to the rollers of the feed table and is supported to move in a horizontal plane above the feed rollers, is made of a length dependent on the length of the pieces to be handled thereby. To the head are connected links 5 having their opposite ends connected to rocker arms 6 on a shaft 7 This shaft may be oscillated to reciprocate the head by any suitable motor mechanism. As shown in Fig. 2 the head projects a substantial distance above the rollers and has its operating face formed at an angle less than 90 degrees, t9 the axes of the feed rollers. The head is pro, tida with a finger e t n n d w wardly between the feed rollers and forwardly of the head, said finger being adapted to strike.
against the tail 9 extending dmvnwardly below the axis of movement of the turninghead 10. This head is pivotally mounted in brackets 11 secured to one of the side frames of the feed table and is normally held with its'operative. face at an angle less than 90 degrees to the axes of the rollers by weights 12 connected to the turning head by flexible means. f e I During the rolling operation the shifting head 1 is at one side of the feed table and the turning head in the position shown in 2. When it is desired to turn the piece lying on the rollers, the head 1 is moved to the right thereby pushing the piece along the rollers and causing the slab to move up'onto the face of the turning head as shown in Fig. -Bv a further -movement .of theshifting head 1 the finger 8 will strike the tail 9 and rotate the turning head to the position shown in Fig. 4 so that when the head 1 is withdrawn the piece will drop onto the rolls and complete its turning movement through an arc of 180 degrees, and permit the turning head to be returned to the position shown in Figs. 2 and 3.
In order to facilitate the lateral movement of the piece onto the turning head the latter is provided at its lower edge with. a toe or projection 13 having an inclined face which will extend to and preferably be a plane tangential to the feed roller.
As shown in Figs. 5 and 6 the weight 12 may be omitted, in which case the normal position of the turning head will be approximately parallel with the shifting head, as shown in Fig. 5. When a piece is moved laterally by the shifting head its edge will strike against the turning head above its pivotal axis and force it to the position shown in Fig. 6. As the turning head is shifted to the position shown in Fig. 6
the toe 13 will pass under the piece and lift it sulficientlv far to facilitate the sliding of the piece along the face of the turn ing head. By a continued movement of the shifting head the finger 8 will strike against the tail 9 turning the headlO to'the'position shown in Fig. {1. When the shifting head is withdrawnthe slab will'drop onto the rollers completing its turning movement and'the head 10 will be in tending along the table in the path of the lateral movement of a piece, said head being adapted to be turned to receptive position by the piece being rolled and to be turned in the opposite direction by the shifting head.
2. The combination of a feed table for rolling mills with a pivotally mounted turning head provided with a forwardly projecting tail, a head movable transversely of the table and having a backwardly inclined operative face and provided with a forwardly projecting finger adapted to engage the tail on the turning head to shift the latter a toe or projection on the head adapted to lift the forward edge of the piece on the feed table as the piece is moved transversel of the table;
3. The combination of a feed table for with a tail extending into the path of movement of the finger on the shifting head whereby the article may be turned through an are greater than 90 degrees.
In testimony whereof, I" have hereunto set m hand. a
.'WILLIAM L. DITGES.
