My invention relates to a sheet transfer mecha nism for rolling mills, and particularly to open mills which have a plurality of stands arranged side by side in a line. It is' an object of my invention .to provide a mechanism by which sheets can be transferred at'will from any one of the stands of an open mill to any other stand for further treatment. (Cl. 80—-44) the gangways 24 clear. Now for transferring a sheet S from a roller table I2 to one of its two adjacent-conveyers M, the rollers R6 are raised above the surface of the roller table l2, by pull ing the rod 2| to the left in Fig. 2.

' r For this purpose, one of the bell cranks Iii-in the Figures 3-5 that controlling the right hand roller set—is directly connected to rod 2|, : With these and other objects in view, I‘ will 15 now describe my invention more in detail, refer whereas the other crank is connected to that ence being had to the annexed drawings, in the length of the lever arm of left-hand crank I9 with respect to rod 2!. Attached to the links which ’ Fig. 1 is a plan view and Fig. 2 is a side view of a sheet transfer mecha nism according to this invention, Figs. 3, 4 and 5 are side views of its distributing elements in three different working positions. In the drawings, l0 and II are two stands of an-open sheet mill arranged side by side, each of them having-,a roller table l2 in front of them, as is well known in the art. Between the stands a, roller table 13 is located for passing sheets back to the other side of'the stands, ‘where for instance furnaces may be arranged for annealing the sheets before entering one of the stands. In thev drawings, only two of the stands of an open sheet mill vare represented, it being well rod by a system of links 25, which permit varying 15 25 is a hand lever 26 which can be rocked about a certain'angle to e?ect the necessary adjustment of the links. A notched sector 21 is provided on an extended arm of crank l9 adapted to be engaged by a lug on lever 25 so as to secure the latter in the desired position. When the two sets of rollers iii are moved in unison, hand lever 26 engages with the central 25 notch of sector 21 (Fig. 3). For causing a rela tive motion of one set of the rollers 15 with respect to the other, hand lever 26 is engaged with one of the two outer notches of sector 21, as will be clearly seen from Figs. 4 and 5. 30 Of course, ‘any other suitable means can be used for varying the motion of the one set of understood, however, that ‘my invention can be rollers I6 with respect to the other, for instance used with any number of stands. ‘ In order to convey‘ a sheet S delivered from a cam control. any one of the stands to another, conveyers M are provided for interconnecting the roller tables l2. For delivering the sheets from a roller table l2 to a conveyer l4, distributors l5 4:0 are provided between each roller table and the abutting ends of the adjacent conveyer. Each of said distributors comprises two sets of rollers [6, one at each side of a roller table l2 having their axes disposed normally to the axes of the rollers ' of the tables l2 and parallel to the conveyers M. The rollers l6 are carried by curved levers I‘! which are operated by means of links l8, bell cranks l9, pivoted at 20, and a common rod 2!, actuated by a suitable crank mechanism, not shown. Normally, when no sheets are to be transferred, the distributors l5 are in their inoperative posi tion, as shown in Fig. 2, in which position their rollers l6 are swung sidewardly down and below the surface of the roller tables l2 so; as to keepv In Means are provided for swinging the two sets When all the rollers Q6 of both sets of the distributor I5 are moved the same distance, the sheet will maintain its horizontal position. For delivering a sheet from the distributor rollers IE to a conveyer l 4, one set of the former is raised above or lowered below the other set, so as to 40 place the sheet in an inclined position causing it to slide off and down onto the conveyer to which it is to be fed. The frames of the conveyers M are supported at both ends on uprights 32 which have wheels 33, resting on tracks 34. The conveyers M are normally below the plane of the roller tables l2 and of the distributors l5, ‘when the latter are in their raised position. To enable the conveyers M to be placed with their ends into registration 50 with a roller set H5, both uprights 32 have a lift ing mechanism to raise the conveyer I 4 at its ends. Each lifting mechanism comprises a shaft 35 adapted to be actuated by a rod‘ 36 from any suitable means not shown. Shaft 35 has a de 55 2 2,050,306 pending lever 3'! to which is pivoted a cross beam 38. The latter has pin and slot connections at its two ends with bell cranks 39 pivotally attached to lifting rods 40 which are pivotally connected with the uprights 32. It will be readily apparent from the foregoing that on shaft 35 being rocked in a, clockwise direc tion, the right upright 32 of Figs. 1 and 2 will be 10 mills, having a plurality of laterally disposed stands provided with roller tables, conveyers lifted from its track 34 and the conveyer M will forming a transverse interconnection between thereby assume an inclined position, sloping said roller tables and means located between each downwardly to the left in Fig. 2, as indicated by roller table and its adjacent conveyers and adapt the dotted lines in said ?gure, whereas when shaft 35 is rocked in a counterclockwise direction, the left upright 32 will be raised and the conveyer l4 ed to deliver a sheet from the roller table to said conveyers, said means comprising two sets of sup assume an inclination to the right in Fig. 2. Any conveyer l 4 can thus be brought into regis tration at its two ends with the raised rollers l6. When a sheet S is transferred from one dis tributor to the next, the conveyer [4 between them is raised at ?rst at the end of the discharg tudinal axis of the roller table, and means for raising or lowering one set of said supporting members relative to the other set. 4. In a sheet transfer mechanism for rolling ing distributor, after that whereupon the sheet is fed along the conveyer M, which, at the same time, is lowered at that end and raised at the other, so that the sheet can easily pass from con veyer M to the receiving distributor I5 the rollers l6 of which having previously been moved into the right position. It will thus be seen that in this way a sheet can be transferred from any roller table l2 to any other without passing the inter mediate tables or stands. It is further to be noted that the conveyer M will be above the roller tables 13 which are ar porting members, one at each side of the longi mills, having a plurality of laterally disposed stands provided with roller tables, conveyers 2.1. forming a transverse interconnection between said roller tables, delivery means located between each roller table and its adjacent conveyers and adapted to deliver a sheet from the roller table to said conveyers, and means for lifting said con- " veyers at one of their ends so as to bring them into proper alignment with said delivery means. 5. In a sheet transfer mechanism for rolling mills, having a plurality of laterally disposed stands provided with roller tables, conveyers veyer I4 is raised at one end, but that the roller forming a transverse interconnection between said roller tables, and means located between each roller table and its adjacent conveyers and adapt ed to deliver a sheet from the roller tables to said tables l3 are on the other hand above the con conveyers, said means comprising a set of rollers 1'v. - veyer, when the latter is in its downward posi tion. By the lifting movements of the conveyer being suitably controlled, a sheet can be trans at each side of the longitudinal axis of the re ranged intermediate the tables l2, when the con ferred also from a conveyer I4 to a roller table l3. it) said roller tables, and means located between each roller table and its adjacent conveyers and adapt ed to be tilted about the longitudinal axis of their respective roller tables for delivering a sheet from the roller table to said conveyers. 3. In a sheet transfer mechanism for rolling In the embodiment shown, the conveyers M are chain conveyers of any suitable construction. Of course, any other type of conveyer can be used instead. I claim as my invention: 1.
