One of the principal-objectsofthis invention' is to improve the adjusting means for the abrasive elements so as to enable the diameter. of the tool to be varied throughout a wide'range oftravel and, I

Another object of this invention is'to provide adjusting means for the .abrasiverelements which is not only simple and compact lin construction,

The inner S111f30850f1l3h scrolls arepr'ovided with helical teethandithese teeth respec- 'tively engage corresponding teeth formed on 01)- posite ends of the holders; The arrangement is suchthat rotation of the scrolls in one 'direction moves the holders .12 radially outwardly with-respect to the cage and rotation of theiscrollsin the opposite direction moves the holders l2 radially inwardly relative to thecage. This adjustment of the .abrasive'elements I3 is accomplished by the .means to be presently described and is important because it enables adjusting the toolto various difierent diameters.
*The cage Ill is rotated byia head it comprising *principallytwoparts Iii-and 2th The part It is formed with aniahnular flange 21 concentric with the axis'of rotation v of the head and sthreadedfor deta'chableengagement with the part 20. The
part 20: isrprovided with atapered spindle 22 adapted to engage a suitable driving mechanism notshown herein. i The part. I79 isalso provided with a hub 23 adapted to telescopically ireceive one endt'of a torque transmitting tube 24 'andlseoured :to :the
tubefl' l by means-of the fastener elementsj2i5. Theo'pposite end .of the tube 26 is internally threaded for detachable :connection with a cou- 'pling sleeveifi adapted torproject into a hub -2-] formedon the headltlof theocage It. ,Upon reie'rence to Figure 4 it will be J noted that a plurality of pins28 project radiallyoutwardlyfrom the coupling sleeve 26 inspacedgrelation to "each other circumferentiallyo-f the sleeve 26 and,respectively, project into:1ongitudinally extending slots 29 'formedin thelhub 2T.

Upon reference to Figure 2 it'will be noted t hat a sleeve .H surrounds the annular flange 21 on V the head in concentric relation to the a xis of ;rotation of the head and this sleeve is formed with an internal helical tooth 32. l One end of the sleeve is rotatably supported on the part l9 of the head and the opposite end of' the'sleev'e operating teeth on a collar 34 which; in turn, is
V V splined on the part for sliding'movementrelative to the head towardand away from-the sleeve '31. The collar 34 is normafly urged in a three: tion'toward the sleeve 3| by a spring35'and,
accordingly,- the sleeve 3| normally rotates as a unit with the driving head l8. o r
The sleeve 3| is-connected to' the scrolls l6 and l! by reduction gearing 3B suitably supported on the driving headilB withintheconfines of the annularflflange 2|. In detail, a bracket 31 is secured to the part I9 of the drivtates the scrolls l6 and n to radially adjust the abrasive elements l3 relative to the cage [0. The
above adjusting mechanismenables the diam-- eter of the tool to be varied throughout a wide range of travel and, owing to the nature of the reduction mechanism 36, permits adjusting the abrasive members to within very close limits of" any preselected diameter in the range of adjustment of the tool. Moreover, the sleeve 3| for efi'ecting the desired adjustment is readilyrac cessible by the operator and, 'acc'ordingly, the adjustment may be made with the minimum loss 1 ,of time. In addition, it will be noted that the x I construction of the tooland associated driving mechanism is such as to enable theparts to be readily assembled and disassembled.
'Referringfnow more particularly to Figure .sofethe' drawingsiit will be noted that the abrais provided with teeth 33 normally engaging cosive elements l3 are each provided with a back-, ing 50 in the form of a flat strip of material having different wearing characteristics than the abrasive element. Theibackingfstrip 50 may be abrasive elements and not onlyminimizes chip-' ping'and breaking of the abrasive elements but 7 illSOlIl'lpIOVGS thesfinish of the surface of the ing'headl8 within theannular flange 2|-and' this bracket supports a shaft 38 for rotation about an axis laterally offset from and extending substantiallyperpendicular.to the axisloii rota L tion of the driving head 18." A pair of'gears 39 are-respectively secured to opposite. ends of the shaft'38 andextend through adjacent slots in the annular flange 2i for meshing engagement with the helical'tooth 32' on the inner surface 'of the sleeve 3|. 1 7
Upon reference to Figure 3. it will be. noted that a worm '40 is secured to theshaft 38 between the bevel gears 39 and'meshes with a worm gear 4| iwhich, in turn, is secured to a-stub shaft 42 j supported on the bracket 3'! for rotation about an axis coincidentwith the axis of rotation of the head. It-follows'from the above that rota- 'tion of the sleeve 3l 'in opposite directionsefiects at 'corresponding rotation'of. the st-ub shaft 42 One end of the stub shaft projects "int'O the tube 2 4 andis preferablypolygonallyoshaped as "through the medium of the reduction gearing 35.
