Abstract

1378238 Grinding BESENBRUCH-HOFMANN Inc 30 Oct 1972 [28 Oct 1971] 49994/72 Heading B3D A grinding tool 10 for a hollow cylinder 58 having an end wall 56 formed with a central hole 57, such as a brake cylinder, comprises a cylindrical hollow hub 12, a plurality of arms 18 pivotally mounted at one end to one end of the hub, a plurality of grinding members 70 respectively removably mounted to the other end of each of the arms, and spring biased adjustment means 40, 42 in the hub bearing on the arms to yieldingly hold them in any one of a plurality of radially expanded positions determined by setting of the adjustment means. The hub 12 has an end wall formed with slots 16 receiving the ends 20 of the arms which are retained therein by pivots 22. The ends 20 are formed with notches 24 engaged by a head 38 of a plug 36, the opposite end of which abuts an adjustable nut 42 screwthreaded into the hub. Adjustment of the nut axially displaces the plug to pivot the arms 18 about the pivots to engage the grinding members 70 with the wall 60. A spring 40 acts between the plug and nut which can be locked in position on a screw 48 by a lock nut 47. The screw 48 is connected by a flexible shaft 52 to a fitting 54 engageable by a driving motor. A sleeve 55 surrounds the hub 12 and can be moved against a spring 53 to hold the arms in a closed position (Fig. 5, not shown), so that the grinding members 70 can be passed through the hole 57 in the end wall 56. A flange 62 on the sleeve limits the movement of the tool through the hole 57. The outer ends of the arms 20 are formed with side walls 32, Fig. 4, having holes for receiving a spring clip 74 the ends of which engage holes 72 in side walls 69 of shoes of the grinding members 70, the shoes being attached to stones 71. The ends of the arms have openings 27 formed with camming surfaces 28 which, upon rotation of the clip 74, retract the ends of the clips from the holes in the side walls 69 of the shoes.
