MEANs r03 TRANSFERRING AND HANDLING METAL PLATES on. THE LIKE. 7
In the usualoperation of transferring plates, for example, from hot or cold banks to a shearing, punching or other machine,
theplates are skidded along the bank by,
mechanically operated skids provided with tongue pieces projecting above the top of the bank, which have to be lowered by a mechaniical operation when the bogie or skid is drawn in one direction and automatically rise again when the other side of the plate is reached. In the other direction of motion the tongue pieces engagewith the side of the plate which is accordingly moved with the skid. As the skid will only operate in one direction, constant manually or mechanically effected changes are necessary, which involve time and labor, and a special disposition of the plates on the bank is required to allow the tongue pieces to engage with the sides of the plates.
According to the invention the process of transferring and handling the plates is very much facilitated by means of one or more electromagnets adapted, when energized, to engage the plate on its under surface and by means of motor driven gearing conveying the magnets on a track in the required direction, preferably by a rope or chain drive.
When the plate is lying on rollers, the upper surfaces of which are on the-same level as the top of the bank, the magnets are arranged to pass between the rollers and when energized are lifted-througha small vertical distance by the magneticv attraction between the plate and the magnets.
here the plate has been transferred to a table and it is required to move the plate to apunching, shearing or othermachine in a definite position for the operation of the machine, rollers are provided on the table, with the axes, for example, transversely disposed with relation to the length of the table, and electromagnets are adapted to Specification of Letters Patent.
move the plates across the table. The rollers in this case, as well as the 'electromagnets, are independently driven by gearing, so that not only can a plate be moved either along or across the table, but byactuating the rollers at different speeds or by reversing the motion of some, the plate can be brought to. any desired angle for presentation to the machine; the electromagnets holding the plate in the desired position.
Each magnet is free to revolve in its own bearings and can act independently. The plate can be rotated by magnetizing one magnet holding the plate near the center and revolving the rollers in opposite directions.
In certain cases it may bev desirable to have an additional magnet fixed near the center of the table in Order that the plate may be revolved about this point, such center magnet being mechanically revolved when assisting in turning the plate. a A l The accompanying drawings illustrate examples of arrangements accordingto the invention.
Figures fl and 2 are respectively a side an end view of means for moving plates by electromagnets ona bank or bed composed of rails; Figs. 3 and 4 are respectively side and end views of means for moving plates by electromagnets on a track composed of idle rollers; Figs. 5 and 6 are views similar to Figs. 3 and 4, in which the carriages supporting the electromagnets run on a single track and are guided by horizontal rollers engaging with the upper ends'of guide bars; Figs. 7 and 8 are respectively a. plan and end view of a movable table on which the plates can be moved longitudinally and transversely and rotated into any required position; Fig. 9is a section on the line 9-9 of Fig. 7.. I I' r In all the arrangements illustrated the i'nagnets are mounted in bearings which: allow each magnet to lift itself when energized into contact with the plate above it.
In the arrangement shown in Figs. 1 and 2, a plate A is supposedto be'lying on a table composed of rails'B to which it has been transferred from an adjacent roller track or on which it has been placed by a crane. r
Electromagnets C supported on carriages D running on rails E are adapted'to move the plate in the. required direction along the table. The electromagnets G are caused to Patented Feb. 3, 1920.

The faces of the magnets are, when deenergized, slightly below the tops of the rails and can pass underneath the plates. When the magnets are energized they are slightly-lifted, adhere to the plate and are moved to transfer the plate to the shearing or other machine, Where they hold the plate in position until the operation is completed, and finally carry the plate from the machine andare then moved back into position for dealing with another plate. These operations are rapidly performed under the control of one person. i
No space is required between the plates as in the ordinary type of skid gear to enable the plates to be handled. f
'In themodification shown in Figs. 3 and 4, the plate A rests on idle rollers I supported by bearings in the rails K. The arrangement can be used to move plates from one part of the works to another, for example, from a rolling mill to a hot or cool ing bank, or to a straightening, punching,
shearing or other machine.
In the arrangement shown in Figs. 5 and 6 the carriages or trucks supporting the electromagnets run on a pair of wheels L disposed in tandem, roller wheels M forming guides for the trucks by frictional engage ment with rails N. r
The arrangement shown in Figs. 7, S and 9 illustrates an example of a movable table 'on'which the plates can be placed from a track or'by a crane and can be moved into any required position for operation at a shearing or other machine.
The plates A rest on two sets of rollers K and K the sets being independently driven by motors'O' and 0 through chain drives H and H shafts P and P and worm'or other gearing Q, and Q.
Magnets C mounted on carriages D are moved on rails R by sprocket chains S through gearing T actuated by motors 0 so as to take up any required position in a direction transverse to the length of the table. The magnets can rotate freely in their bearings about a vertical axis.
In the operation of the arrangement a plate A is firmly held by one or more electromagnets C energized by cables from a source of electric power and is earned into the required transverse position by the movement of the carriage or carriages D onthe rails R by the motors 0.
To slue-the plate into any required angular position a magnet O disposed at the center of the table and rotatable about its vertical axis is energized and adheres to the plate A near the center of the latter; the roller gears K and K are then rotated in opposite directions, and cause the .plate A and the magnet C to take up the required angular direction.
The plate is then moved longitudinally on the table by rotating the rollers K and K in the same direction until it is held near its edges by two or more magnets C.
The magnets are then energized and adhering to the plate are moved independently or together transversely until the plateis in the required position for the operation of the machine, for example, so that a sheardelivers it to any suitably arranged part of the works. The magnets are de'energized, whereupon the rollers K, K? may be rotated in the direction to deliver the plate otherwise as may be required.
All the operations can be rapidly performed under'the control of one person. Having thus described the nature of the said invention and the best means I know of carrying the same into practical effect, I claim 1.
