ROLL HANDLING DEVICE,

Carl E. Moore, Gary, Ind. Application January 15, 1938," Serial No. 185,215

2 Claims. (l. 294-67) This invention relates to rolling mill roll handling devices of the type comprising a beam having a roll neck socket at one end and a counterpoise at its other end. The counterpoise is for the purpose of balancing a roll whose neck is engaged by the socket on the other end of the beam, the latter being suspended by a crane or the like during the process. To efiect proper balancing the beam must be suspended from difierent points, depending on whether the device is handling a roll. The determination of the proper .suspension points and the shifting from one point to another during engagement and disengagement of a roll neck are very ticklish operations,

18 and the primary object of the present inventor is to provide a remedy for this situation.

A specific example of a roll handling device embodying the principles of the'invention is illustrated by the accompanying drawings, in which:

Figure Lisa top' plan of the device Figure 2 is a side elevation; and

Figure 3 is a cross-section taken from the line III-I11 in Figure 1.

More specifically, the device includes a beam I I provided with a suspension plate 2 having a crane hook opening 3. One end of this beam I carries a, roll neck socket 4 while its other end carries counterpoises 5.

. One characterizing feature of the device is the two counterpoises 5 and the mounting of these counterpoises on the end of the beam I by way or vertical shafts Ii journaled through anti-friction ter of gravity of the devicemay be kept directly beneath-the crane hook opening 3 at all times regardless of whether the socket 4 is engaging a roll neck.

The counterpolses 5 are to the shafts 6 so as to turn the same while a gear train Ill, ex tending over the top of the device and interconnecting these shafts 6, serves to compel the'two counterpoises to swing in opposite directionsin synchronism, whereby to prevent canting and loss of control. One of the gears III of the gear train- I0 is provided with a plurality of holes in accessible from the outside of a cover I2 enclosing the gear train to permit insertion of a locking pin I3. The counterpolses may be swung manually, being provided with handles I4 for this purpose, and when properly adjusted so the beam I is horizontal, they may be locked in position by dropping the pin I3 into one of the holes II of the gear III. Other means of locking the counterpoises at any one of a number of different positions may be substituted for this arrangement, although the safety and foolproofness of the 10' latter is an advantage.

The plate 2 connects with the beam I at the counterpoise end by way of a. pin l5 which is dropped in undercut slots I6 formed in a vertical slot between the two arms 8, and there retained 1 by reason of its other end being fastened between spaced ears I'l at'the socket end of the beam by a pin I8 passed through these ears and a hole in the plate 2. This pin ll is removably retained by means of screws I9, it being possible-to remove 20 easily the plate 2 upon the removal of this pin I8 by moving the plate slightly toward the counterpoise end so as'to unhook the pin I5 from the undercuts in the slots Ii.

Although ,a' specific example of the invention 25 has been disclosed in accordance with the patent statutes, it is not intended to limit, its scope exactly to this example, except to the extent defined by the appended claims.

I claim: V v

1. A counterpoise arrangement for a rolling mill roll handling device of the type including. a beam adapted to be suspended by a crane or the like and having a roll neck socket at one end, said arrangement comprising two counterpoises piv-' otedat the end of said beam opposite said socket to swing horizontally and a gear train interconnecting said counterpoises to cause them to swing in opposite directions in synchronism.

'2. A counterpolse arrangement for a rolling 0 mill roll handling device of the type including a beam adapted to be suspended by a crane or the like and having a roll neck socket at one end, said arrangement comprising two counterpoises pivoted at the end of said beam opposite said socket 45 to swing horizo tally, .a, gear traininterconnecting said coun rpoises to cause them to swing in opposite dire tions in synchronism, and means for releasably ocking said counterpoises immovable at diflerent positions.
