  • the directing guide 11 is shownas consisting of two side wallsv 16 and 17 and a floor 18 to provide an elongated trough.
  • the direct/ing guide is provided with a ilare 19 whereby itis adapted to receive the mill product fromV the rolling mill after it has been sheared.
  • the receiving-'end is provided with a vertical pivot 21 by vwhich it is mounted for swinging movement.
  • the directing guide is provided with a downwardlyY prof jecting pin 22 which lies in a slot 23 which is angular to the pass line formed on the upper surface of'a block 24.
  • the block is slidably mounted onthe base 15 for movement longitudinally of the direction of the directing guide 11.
  • a hydraulic cylinder 25 ⁇ mounted on the base 1S provides the force for bringing about the longitudinal movement of the block.
  • the switch guide 12 is provided with an outer fence 26 vwhich extends upwardly from a horizontal upper surface 27. If one disregards the fence 26, the guide 12 y could be described as an elongated solid bar with an inclined passage 28 extending through it. This passage extends diagonally through the guide from the outer forward or receiving corner to theinner rearward corner adjacent the runout table 14.
  • the passage might best be described as a groove, since it is open at the receiving end adjacent the directing guide 11 and is open on the f inner. side, leaving a floor 29 and a roof 31 on which the l upper surface 27 is formed; this configuration is par- 'ticularly [evident in FIG. y7. ln a similar manner, the
  • switch guide 13 is provided with an outer fence 32 which jacent the runout table 14. This passage or groove devsurface 33.
  • .camy members are mounted in parallel relationship and areslidable over the surface of the basel 15; axhydraulic cylinder 45 isfastened tothe base 15 vand Vconnected to the cams to move them back ⁇ and forth as is desired.r vIn this connection, it should be noted Vthat a passage is formed through the base upon which the hydraulic cyl Y* inder ⁇ 25 is mounted and through the block 24,'-these passages being suitably formed to permit reciprocationl of thecarn members 43 and ⁇ 44, independently ofthe block 24.
  • the runout table 14 is provided with an outboard fence 48 which is inv general alignment with the fence 26 of the switch guide 12; at the other side, it is provided with a fence 49 which is in general alignment with the upper outboard fence 32 associated with the switch guide 13. In its center portion it is provided with a divided wall 51 defining a rigl1t-hand trough 52. leading to one cooling bed (not shown) and a left-hand trough 53 lead-ing to another cooling bed (not shown). l'
  • the front portion of the bar residesin the passage 28 of the switch guide 12 and extends over a portion of ⁇ the upper surface 33 of the switch guide 13; its forward end is directed toward the left-hand trough 53 of the runon table.
  • the directing guide 11 is in its right-hand position, the pin22 residing in the righthand extremity of Vthe slot 23.
  • the next step is the actuation of the hydraulic cylinder 25 to carry the block 24 toward the pivot 21. This causes the p in 22 to ⁇ move toward the left-hand extremity of the slot 23 and carry the directing guide 11 to the left and to the position shown in FIG. 2.
  • the switch guide 12 is still in its upper position, while the switch guide 13 is still in its lower position.
  • the bar, b2 now extends in a straight line through the directing guide 11 and over the upper sur face 33 of the switch guide 13. It no longer contacts the switch guide 12.
  • the next step in the cycle carries the parts into the condition shown in FIG. 4.
  • the hydraulic cylinder 45 is actuated to cause the cam members 43 and 44 to be moved forward toward the runout table 14.
  • the posts 38Y and 39 of the switch guide 13 are carried up the inclined surfaces of their cam member ⁇ 43 and this moves the guide 13 to its upper position.
  • the legs 46 and -47 of the switch guide 12 move down inclined surfaces into low positions on their cam member 44 so that the guide 12 occupies its lower position.
  • the ⁇ bar b2 still passes over the uppersurface 33 of the switch guide 13 but this surface now resideswell above the horizontal floors of the directing guide ⁇ 11 and the runout table 14. However, the bar, although it is raised in its center portion by the surface 33, still proceeds smoothly into the left-hand trough 53 of therunon table, guided by the side walls of 11 and 49 and 51 of 14. Eventually, as is shown in FIG. 5, the rear end of thebar ⁇ b2 moves out of the apparatus and the forward end of the next bar b3 presents itself. It moves toward the switch guide 13 because the directing guide 11.is in the left-hand position, and its front end slides along the diagonal surface 35 of the passage 34 formed in the switch guide 13.
  • the upper surface of the oor 36 ofthe switch guide 13 is on the same level as the ⁇ upper surface 27 of the switch guide 1,2, and so the forward end of the bar can pass out of the vpassage 34 onto the surface 27 of the switch guide 12 and then into the right-hand trough 52 of the runon table.
  • the hydraulic cylinder 45 is ,actuated to cause the block 24 to move forwardly away-from the pivot 21 solthat the pin 22 moves again to the right-hand side of the slot 23, and carries" the directing guide 11 to its right position.
  • the bar b3 then slides over the upper surface 27 of the switch guide '12; the bar is'substantially straight because the directing guiderll, the switch guide 12, and the right-hand trough 52 of the runout table 14 are in alignment.
  • the switch guide 13 is still in its upper position, while the switch guide 12 is still in its lower position with its upper surface 27 on the same level as the floors of the directing guide 11 and the runon Itable 14.
  • the switch guide 12 As the bar proceeds along, its tail end is eventually Withdrawn from the switch guide 12 and the front end of the next bar is about to pass into the apparatus.
  • the positions of the switch guides 12 and 13 are reverscdso that the switch guide 12 is in its upper position and the switch guide 13 is in its lower position; the bar b3 as it passes into the trough 52 is supported in its center portion on a high position of the surface 27.
  • the forward end of the next bar is guided through the passage 28 into the lefthand trough 53 and the cycle repeats itself.
