ELECTRIC CATCHER AND CONVEYER.

Application filed December 4, 1923. Serial No. 678,410.

To all whom it may concern:

Be it known that I, WILLIAM A. F rrz- SIMMONS, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Electric Catchers and Conveyers, of which the following is a specification.

This invention relates to mechanism for catching sheets of steel and the like as they emerge from cold rolls, shears, bucklers, presses, stamping machines, and other machines through which cold sheets are passed; and for conveying the sheets away from the nilachine and depositing them in'any desired ace.

The objects of the improvement are to provide a machine of this character having an endless belt carrying electro-magnets arranged to catch each sheet as it emerges from the cold rolls or other machine and carry the sheet away from the machine and deposit it at a suitable place away from the machine.

Although the improved catcher and conveyer may be applied to numerous sheet handling machines, for the purpose of illustration it is shown applied to a cold rolling mill in the accompanying drawings, in wh1ch- Figure 1 is a side'elevation of the electric catcher and conveyer attached to a cold rollig 2, a fragmentary plan view of'a por tion of the endless belt which carries the ma nets;

igs. 3 and 4, detail views of the pulleys over which the belt travels; and I Fig. 5, a section on the line 5-5, Fig. 1.

Similar numerals refer to. similar parts throughout the drawings.

A portion of the housing of a cold rolling mill is shown at 1 and. the rolls thereof at 2, the usual table 3 being located in position to receive the sheets upon the fiber rollers 4, as they emerge from the rolls of the mill.

The improved catcher is mounted in a frame comprising the side members 5 con nected to ether in suitable manner and. provided wit the notches 6 at one end for engagement with the rest bar 7 of the mill, the other end being preferably provided with uprights 8 to which are connected sus pension braces 9, which may be attached to the housings of the mill.

A platform 10 is supported upon the side members 5 and carries a motor 11 having a pinion 12 upon its shaft meshing with a gear 13 upon a countershaft 14. A sprocket 15 is fixed upon the shaft 14 and connected by the sprocket chain 16 with a similar sprocket 17 fixed upon the shaft 18 of the pulley 19.

This pulley is preferably provided with an' insulated periphery and carries a conductor ring 20 near one side thereof. A similar ulley 21 is located at the forward end of t e frame and provided with a conductor ring 22 located near the other side, an endless belt 23 being located around said pulleys and provided with the woven wire conductors 24 and 25, arranged to engage the conductor rings 20 and 22 respectively.

Electro-magnets 26 are connected at close intervals to the belt 23, each magnet being connected to both of the conductors 24 and 25. A brush 27, connected to one side of an electric circuit, is permanently held in contact with the conductor ring 22 upon the pulley 21.

A brush 28 is mounted for slidable movement upon the frame and connected by a link 29 with the upper end of a lever 30 pivoted intermediate its ends as at 31 to the frame, and arranged. to normally-hang in the vertical position, as shown in Fig. 1, holding the brush 28 out of contact with the conductor ring 20 of the pulley 19.

A fiber roller 32 is journaled upon the lower end portion of the lever 30 in the path of sheets emerging from the rolls of the mill.

As the forward end of each sheet passes over the rollers 4 upon the table 3 and contacts with the'fiber roller 32.upon the lever 30, the lever will be tilted by the sheet, permitting the same to pass under the roller 32, this tilting of the'lever moving the brush 28 into contact with the conductor 20 back to its normal position, disengaging the brush 28 from the conductor ring 20, breaking the circuit through the conductors 24 desired point where the magnets are automatically deenergized by the sheet passing out of engagement with the fiber roller upon the lever 30, thus obviating the necessity of providing an operator for the catcher and oonveyer.

I claim 1. A. catcher and conveyor for receiving moving sheets, including an endless belt, magnets upon .the belt adapted to attract the sheets, and means operated by the movement of the sheet for ailtomatically energizing the magnets.

2. A catcher and eonveyer for receiving moving sheets, including an endless belt, magnets upon the belt adapted to attract the sheets, and means operated by the movement of the sheet for automatically energizing the magnets at a predeterminedpoint and deenergizing the magnets at a predetermined point.

,ductor ring.

rename electro-magnets upon the belt, a movable brush for closing the circuit to said mag= nets, a pivoted lever operatively connected to the brush and located in the path of the sheets, and a fiber roller upon said lever for engagement with the sheets.

5. A catcher and conveyer for receiving moving sheets, including an endless belt having two endless conductors mounted therein, ulleys over which the endless belt is located a conductor ring upon each pulley engaging one of the conductors in the belt, a brush permanently en agin one conductor ring, a brush norma 1y he d out of engagement with the other ring, electromagnets upon the belt connected to the conductors and means operated by the movement of a sheet for automatically engaging the last named brush with the adjacent con- In testimony that I claim the above, I have hereunto subscribed my name.
