2 Claims. (Cl. 51-253) This invention relates to a rolling mill polisher polishing units 16 being provided for the upper and has for an object to provide an oscillating roll 13 and polishing unit 1'7 being provided for roll polisher for use on rolling mills. As is well the lower roll 14.

The bracket mill 10 consists o a hellsing 11 d 12 having box 38 of each polisher 16 and 1'7 is provided 45 th rolls 13 and 14 twe n whi h h t st el is with a socket 44 to receive the ball ends 45 of rolled in the usual manner.

The ball ends 47 formed on rolled between the rolls 13 and 14, scale and forthe other end of the connecting rod 46 are reei n m r is deposited on the surfaces of h ceived in sockets formed in extensions 48 on the T0 8 13 and Causing them 0 e e U eve nut 49, the nut 49 being a reversible nut and 50 and making them unsuitable for further use. traveling along the reversibly threaded screw 50 This invention provides means for restoring a between the screw bearings 51 and 52. The bearsmooth and even contour of the rolls 13 and 14, ings 51 and 52 are secured to the housing 11 by placing them in condition for continued use. means of bolts 53, the bolts 53 also acting as The polisher 15 constituting this invention conguides for the nut 49 through the intermediary of 55 sists of a pair of polishing units 16 and 17, the the extension 48.

The screw 50 has secured thereto a bevelled gear 54 connecting with another bevelled gear 55 mounted on a shaft 56. The shaft 56 is supported in a bearing 57 on a bracket 58 secured by stud bolt 59 to the housing 11. Mounted on the shaft 56 is a worm wheel 60 cooperating with the worm gear on the shaft 61 of the wheel 62. A belt 63 supplies power to the Wheel 62 from any suitable source, such as the power wheel 64.

In operation, the power from the wheel 64 through the train of gears just described, rotates the screw 50 causing the nut 49 to travel back and forth thereon between the bearings 51 and 52. The connecting rods 46 causes the polishers 16 and 17 to travel back and forth on the extensions 19 and 20 of the brackets 21 and 22, the ball and socket joint at each end of the connecting rods 46 allowing the polishers 16 and 17 to be rotated against the rolls 13 and 14 by means of the weights 27 and 28. Thus the polishers l6 and 17 as a whole oscillate back and forth across the surface of the rolls 13 and 14 as the same are rotated. Should a raised or hard spot on one of the rolls come into contact with one of the individual abrasive blocks 35, that particular block 35 will be forced back into the bracket box 38 against the telescopic spring 39, thus causing extra pressure on the raised spots and reducing the raised spots to the level or contour of the roll.

The novel features and the operation of this device will be apparent from the foregoing description. While the device has been shown and the structure described in detail, it is obvious that this is not to be considered limited to the exact form disclosed, and that changes may be made therein within the scope of what is claimed without departing from the spirit of the invention.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

1. A roll polisher comprising an abrasive means, pivotal means for mounting said abrasive means on a rolling mill housing tending to force said abrasive means against the rolling mill rolls, an extension means on said mounting means, means for causing said abrasive means to oscillate across the roll surface, said oscillating means comprising an abrasive holding bracket slidable on said extension means, and means for sliding said bracket on said extension means, said latter means comprising a rotatable reversibly threaded screw, a reversible nut mounted on said screw, and connecting rod means, said connecting rod means having ball and socket connections to said nut and to said bracket.

2. In an oscillating rolling mill polisher, a bracket, a plurality of abrasive block holders mounted in said bracket, an individual abrasive block in each holder, lug means on each holder, groove means in said bracket providing paths for said lug means permitting said holder to be de pressed into. said bracket, and telescopic spring means in said bracket beneath each individual holder yielding to permit said holder to enter said bracket and tending to force said holder outwardly of said bracket.
