Specification of .Letterl ratent. Patented Sept. 13, 1921.

Application filed January 17, 1920. Serial No. 352,067.

To all wlwmit'may concern: I Be it known that I, JOHN S. WORTH, a citizeniof the United States, and a resident of C'oatesville, Pennsylvania, have invented certain Improvements in Roller Transferfollowing is a specification.

My-invention relates to certain ments in tables for transferring metal sheets from the rollin mill to the shearing machines or to cooling tables.

One object of my invention is to provide the transfer table with power driven rolls which traverse the plates over the table.

A further object of the invention is to provide the turn-over apparatus, in which the plates are turned over, also with power driven rolls, as well as the arms that receive the plates from the rolling mill table and deliver the plates onto the shears table.

These ob sets I attain in the following manner, re erenoe being had to the accompaiirying drawings, in which :v

gure 1 is a diagrammatic plan view illustrating my improved transfer table located between the rolling mill table and the shears table;

Fig. 2 is 'a diagrammatic sectional view on the same scale as Fig. 1, the section being on the line2-2, Fig. 1; Fig. 3 is an enlarged plan view illustrating one section of the transfer table;

Fig. 11 is a. plan view illustrating one of the transfer arms;

Fig. 12 is a sectional 12-12, Fig. 11; and

Fig. 13 is a sediionalview on the line view on the line 1 is are g mill, inthe present instance improve" can be of any design desired. 2 is a table on one side of the mill and 2 is a table on the opposite side of the 'mill. These tables can be manipulated so as to pass the bloom or blank back and .forth through the rolls until it has been reduced to the pro r thickness, after which the rolls of the ta le 2 can be manipulated so as to transfer the plate onto a roller table 3, which may be of any length desired. Straightening rolls may be provided for straightening the plates in this section. 3 indicates mechanism for transferring the plates from the table 3 to the table 4:. The rolls of the tables are driven in the ordinary manner. 5 is a roller table in which the rolls are driven. This table directs the plate to the shearing machine 5" at one end of the rolls 5. The shearing machine may be of any ordinary type for cut ting plates into any shape desired.

ted between the roller table 4 and the roller table 5, are the transfer tables 6, made in four sections, as shown. Each Bection has a series of rollers 7 mounted on driven shafts 8, the shafts of each section bein driven from a centrally located motor 9. he rollers roject above the surface of the frame so 515th a plate placed on the transfer table will be supported by the rollers, and, as these rollers are driven, the

plates will be transferred over the surface of the table 6 from the rolling mill table 4:-

to the shears table 5. By arranging the transfer tablein sections and providing each section with an independent motor, 7 the plates on the several sections can be controlled independently when it is desired to allow certain plates to cool a greater length of time than others, and also allows for the [manipulation of certain t1plates rolled after ey can be cut im-' previousplates, so that mediately without having towait for the transfer of plates that have been previously rolled and which can be delayed.

Located between the two sets of tables 6 is the turnover apparatus 10, consisting of shafts 11 having arms 12, on which are rollers 13. These rollers are driven so that when the arms are down, as illustrated in Figs. 1 and 2, the late can travel directly from the rolling of the transfer table, then over the turnover and onto the outer section of the transfer table and to the shears table. When it is 1 table over one section ber of rollers.

desired to examine both sides of a plate, as is now the generalpractice, the plate passes from one section of the transfer table to a series of arms on one side of the turnover apparatus. Then, the two series of arms are raised until they assume the position illustrated in Fig. 6, when the plate is transferred from one series-of arms to the other. The arms are then lowered to their original position, the plate being turned over and resting on the second series of arms, so that the inspector canexamine both sides of the plate. As the arms are provided with driven rollers, the plate immediately passes from the arms onto the second section of the transfer table, and is traversed by the rolls of this transfer section to the shears table 5.

In order that the plates may be transfer red from the rolling mill table 4 to the transfer table 6, I provide a shaft 14 with arms 15 having rolls 16. These arms 15 are raised when the plate is in position so as to lift the plate from the rolls of the rolling mill table. As soon as they are resting on the rollers 16 of the arms, these rollers immediately feed the plate onto the transfer table 6. A similar shaft 14 having arms 15 with'rollers is provided and is locatedbetween the transfer table and the shears table 5 for the purpose of transferring the plates from the transfer table to the rollers of the shears table.

The above description gives a general idea of the arrangement of the transfer table in respect to the rolling mill table and the shears table.

Y Heretofore, it has been the general practice to use endless chains for moving the plates over the transfer table. The use of chains is not satisfactory, but, by the use of driven rollers, I find that the plates can be readily manipulated, and, when desired, the plates can be manually shifted on the rollers, as there is comparatively little bearing of the plate on each roller. Furthermore, the weight of the plates on the rollers gives the rollers sufficient traction to move the plates properly on the transfer table. 7 In referring to Figs. 3 and 4, which illustratea portion of one section of a transfer table, the frame consists of a series of longitudinal beams 17 having boxes 18 for the shafts 8, which'are spaced a given distance apart, and on which the rollers are located -mg transferred, will be supported by a num- In the present instance, each pair of shafts "-8 has gear wheels 19, which mesh with gear wheels 20 on a short shaft 21. On each 'short shaft isa bevel gear wheel 22 which meshes with a bevel gear wheel 23 on a lon- Qgitudil fil shaft 24. The shaft 24 drives a number drama shafts-21 and on the shaft 24 is a' gear wheel 25 which meshes with a a g1ven distance apart so that a plate, be

to one. section may not 'be gear wheel 26 on another longitudinal shaft 27. The gear wheel 25 is located about midway between the ends of the shaft 24.

There are two longitudinal shafts 24 to each section and two longitudinal shafts 27, as illustrated in Fig. 3. Each longitudinal shaft 27 has a bevel gear wheel 28, which mesheswith a bevel gear wheel 29 on a transverse shaft 30, which is driven from the motor shaft 31 through shafts 32, 33 and 34, having reducing gearing so that the rollers will be driven at the proper speed. This gearing may be changed without departing from the essential features of the invention. By this construction,-however, all of the rollers are driven at the same speed.

The turnover apparatus is shown clearly in Figs. 5, 6, 7, 8 and 9. The two shafts 11 are spaced a given distance apart and are adapted to

bearings

35 and 36 on suitable foundations. On the shafts is a series of gear wheels 37, which mesh with a pinion 38 on. a central shaft 39. The gear wheels '37 mesh'with a train of gears 40 Ion the arms 12, and each alternate gear wheel in the train 40 has flanges whiclnact as a bearing roller13 for the plates.

Motion is imparted to the shaft 39 through a train of gears 41, 42 and 43, the latter wheel being on a shaft 44. On this shaft is a gear wheel 45 meshing with a pinion 46 on a shaft 47, on'which .is a gear wheel 48. which meshes with a pinion 49 on a shaft 50. 011 this shaft 50 is a gear wheel 51 which meshes with a-pinion 52 on a driven shaft 53 of a motor 54. By this construc tion the rollers are driven. irrespective of the position of the arms 12, as the rollers of the arms are always in gear with the power mechanism.

In order to raise and lower the arms, I provide hydraulic cylinders 55one cylinder for each series of arms. Each series of arms is fixed to an independent section of shaft 11. There are four sections, in the present instance. The cylinders are pivotally mounted at 56 on suitable bearings 57 and plun ers 58 of the cylinders are pivotally attac ed at 59 to a cross head 60, which, in turn, is pivotally connected at 61 to two of the arms 12. As these arms are fast to their shafts 11,- any movement imparted to them by the plungers 58 will be imparted to the series of arms. on the said shafts.

In some instances, where extra heavy plates areto be turned over, power applied sufiicient to lift the plates. I, therefore, provide the adjacent ends of 'the'alining sections ofthe shaft 11 with couplings 64, which are normally free," so that the two adjoining sections of the turnover will act independently. When it is desired to increase the power, I may couple the two shafts together and use the cylinders of the two sections to lift the plates. Secured to each section of the shaft are counterbalance arms 62 having adjustable weights 63, which tend to counterbalance the overhang of the arms 12.

The construction of the arms for transferring the plates from the rolling mill table to the transfer table, and from the transfer ta ble to the shear table, issomewhat similar to the construction of the arms of the turnover.

Referring now to Figs. 11 and 12, the arms 15 are mounted on the shaft 14, which is adapted to suitable bearings 68,'and has a gear wheels are flanged to form the bearing that chains are entirely dis rollers 16 and project above the upper surface of the arms, as clearly shown in Fig. 11.

It will be noticed'on referring to Fig. 1, that the transfer arms are divided into sections corresponding with the sections of the transfer table, and are driven from their respective sections. Extending under the arm is a rock shaft 76 adapted to suitable bearings 77. On this rock shaft is an arm 78 attached to a plunger79 adapted to a hydraulic cylinder 80, so that when fluid is admitted to this cylinder, the arm 78 will be raised and will rock the shaft 76. 81 are counterbalance arms having adjustable weights 82.

On the shaft 76 are arms 83, one located under each transfer arm 15. Pivotally con nected to the arms 83 are links 84, slotted at their upper ends to receive pins 85 on the transfer arms, so' that when the arms 78 are moved upward to rock the shaft 76, the links 84 push the arms 15 up above the rollers of the rolling mill orv shears table, and if a plate be on the rolling mill table, it will be elevated clear of therollsof said table by the arms 15. As the rollers on these arms rotate, they transfer the plate onto the rollers of the transfer table, and when it is desired to transfer a plate from the transfer table to the rollers of the shears table, the arms are raised and the plate is traversed over the arms .by the power driven rollers. When the plate is above the rollers of the shears table, then the arms are lowered, so that the surfaces of their rollers are below the rolls of the shears table, and the plate will rest on therollers of the shears table and will be fed toward the shears on motion being imparted to said rolls. a

ensed with, and

that the entire manipulation of the plate from the rolling mill to the shears is by driven rollers, the movement of the rollers .ing from the While I have the above construction, it will be seen being under the control of an operator. The plates can be turned as they are traveling from the rolling mill table to the shears table withoutmanual labor,'but when it is desiredto shift any of the plates laterally on the tables, this can be readily accomplished by the rollers;

The entire mechanism, in the present instance, is electrically driven from a series of independent motors under the control of an operator, so that therollers of anysection of the table can be readily stopped, if desired. While I have illustrated electric motors as the power for driving the rolls, other power may be resorted to without departessential features of the invention.

In some instances, I may use a series of supporting rolls arranged on a line extending through the center of each section, as shown at 7*, Fig. 1. These rolls are not driven, but simply support the plate and prevent buckling.

made in four units, the number of units may be increased or diminished, as desired.
