Definitions

  • the drive member is formed with a hollow threaded boss, disposed through a centrally defined opening in the article, and an outwardly extending member at the base of the boss disposed on the opposite side of the article to press the article against the support pad.
  • the outwardly extending member can be formed with a plurality of tabs which are pressed into engagement with backing material of the article whereby to secure the drive member in intimate integral connection with the article.
  • the support pad includes a core-socket member and an axial stud whereby the drive member boss may be threadably retained in female-male engagement with the stud and core member, respectively, the core member being formed with internal and external abutment surfaces for close fitting engagement with the top surface of the drive member and surfaces of the finishing article laterally thereof, respectively.
  • a finishing article incorporating a drive member which is highly reliable during use under all conventional temperatures and stresses and which is readily attachable to available support members.
  • the drive member is of such simple construction as to enable the fabrication of driven abrasive finishing articles at very low cost.
  • the drive member comprises a hollow boss having an annular screw thread lip and which is formed with a member extending outwardly from the base thereof. The boss is inserted through an axial opening in the finishing article with the outwardly extending member disposed on the finishing side of the article, the drive member may be secured to the finishing article by any of a variety of methods.
  • the drive member may be press fit through a slightly smaller opening in the finishing article or it may be glued to the finishing article.
  • the gripping ears may be punched through the outwardly extending member and bent over and pressed into biting engagement with the backing material of the finishing article to thereby mechanically and intimately secure the drive member to the finishing article.
  • the finishing article can thus be provided with an integral drive member by simple mechanical operations allowing for rapid and economical manufacture of the article.
  • the lip of the hollow boss is broken and curved inwardly to define an internal screw thread.
  • the boss functions as a female component receiving the threaded axial stud of a support member.
  • the support member is formed with an axially central retainer socket, about the stud, for mating engagement with the exterior surface of the boss.
  • the boss functions as a male component receivable within the socket.
  • the drive member functions both as a female and a male component to obtain a structurally strong connection.
  • the vertical distance between the top surface of the boss and top surface portions of the finishing article laterally of the boss is controlled to a predetermined magnitude so as to accomplish close-fitting mating engagement of both surfaces with the central socket.

  • an abrasive finishing article 10 in the form of a circular disc having backing material 12, such as fiber, cloth or the like, on one side and abrasive finishing material 14 on the opposite side.
  • the finishing article 10 is formed with a drive member 16 axially central thereof and which is mechanically fixed by means of tabs or piertors 17 pressed in intimate integral gripping connection with the material of the backing member 12 as will be described in more detail hereinafter.
  • the drive member 16 is formed with a hollow boss 18 open at its outer end and having a lip 20 broken at 22 and curved inwardly to define an internal screw thread.
  • a rotatable support member 24 is formed with a flexible flat-surface support pad 26 of rubberized material or the like.
  • the support member 24 is of a type which is readily available and is described in detail in my earlier application, Ser. No. 806,250, entitled Finishing Article and Support Member Therefor.
  • the support member 24 receives a central connecting stud 28 whereby the support member is secured to a rotatable power tool.
  • the connecting stud 28 extends through the support pad 26 and terminates in a threaded stud portion 30 which is formed to matingly engage the threaded lip 20 of the drive member 16.
  • the bottom surface 32 of the threaded stud portion 30 may be substantially on a plane with the bottom surface of the support pad 26, however, the bottom surface of the support member 26 is formed with a central recessed portion 34 to accommodate the tabs 17.
  • the finishing article 10 is formed with a central opening 36 slightly greater in diameter than the width of the hollow boss 18 and, in most instances, is a in'ch hole which has become somewhat of a standard in the industry.
  • the drive member 16, as illustrated, is fonned with an annular flange 38 radiating from the base of the boss 18 for disposition against the abrasive material side of the finishing article 10.
  • a plurality of tabs 17 are punched through the flange 38 and extend upright therefrom annularly about the boss 18.
  • the drive member 16 preferably is constructed of a sheet metal material, such as cold rolled steel, and is formed integrally in one piece from a disc, as by stamping or the like, on progressive dies, so that the threaded boss 18 and tabs 17 are formed in a traditional stamping operation.
  • the present design of the drive member 16 thus allows for very economical manufacture.
  • the tabs 17 are formed so as to fold up from the flange about the periphery thereof and are sufficiently spaced from the boss 18 so as to define a clear area 40 as shown by the arrow (FIG. 4) for purposes hereinafter described.
  • the tabs 17 are inserted through the material of the finishing article, as by puncturing the same, to project from the backing side 12 thereof.
  • the construction of the abrasive finishing article of the present invention provides a device which carries with it the drive means for securing the device to the power tool for rotation but at the same time provides an extremely economical finishing article that is totally discardable when the abrasive surface is worn down.
  • Such devices have been provided for relatively small diameter abrasive discs in the past, no such structure meeting all known standards has been available for resin-fiber type abrasive discs having large diameters, i.e. seven inches and above. Such large diameter discs have been employed with a central opening which fitted over the stud.
  • a machine screw threaded nut having a flange thereon was then threaded onto the stud and tightened with a wrench. To remove the disc the nut had to be loosened with a wrench, removed, saved and reused with a new disc.
  • the discardable disc-drive unit of the present invention much more efficient operation of the device can be accomplished.
  • the finishing article is illustrated after insertion of the boss 18 through the central opening 36 and the tabs 17 through the material of the article, and after the tabs 17 have been bent and pressed into biting engagement with the backing material 12.
  • an annular member (not shown) is brought down onto the top surfaces 42 of the tabs 17 while the flange 38 is disposed against a supporting a'nvil (not shown).
  • The-tabs 17 are thus bent over into pressing engagement with the backing material 12 so as to bite into the backing material 12, thereby pinching or gripping the material between the tabs 17 and the adjacent portions of the flange 38 as shown at 43.
  • a strong mechanical connection is thus effected between the drive member 16 and the finishing article 10.
  • the support member 24 is provided with an axially central socket member 31 which is formed with a hollow 33 through which the threaded stud portion 30 (shown in shadow) projects.
  • the drive member boss 18 is received in the hollow 33 which is as deep as the effective height of the boss 18 so that the top surface 44 of the boss 18 is close-fit against the socket roof defining the hollow 33, while the top surface 45 of the aforenoted clear area" 40 is clamped against the bottom surface 46 of the socket member 31.
  • the socket roof 35 is closely fit to the threaded stud portion 30, and forms a metal trap" against the drive member boss 18 so that there is no slippage between the abrasive finishing article 10 and the support member 24.
  • the vertical distance between the top surfaces of the boss 18 and the top surface 47 of the backing member 12, as indicated by the arrow 48, is thuspredeterrnined with respect to the requirements of a particular support member 24 and is slightly shorter than the depth of the socket hollow 33.
  • a drive member 50 is provided having a hexagonal shaped boss 52 formed integrally with an annular flange 54 extending outwardly'from its base.
  • the boss 52 is formed hollow with a split lip in the manner of construction of the boss 18 of FIG. 2.
  • the finishing article 56 to which the drive member 50 is to be attached is formed with a central opening 58 in the outline of a hexagon which is dimensioned so as to be slightly smaller than the outer dimension of the boss 52.
  • the drive member 50 is secured to the finishing article 56 by press-fitting the boss 52 into the opening 58 to thereby mechanically secure the drive member 50 to the finishing article 56 through frictional engagement therebetween.
  • the finishing article 62 is provided with a central opening 64 which may be round and which is dimensioned so as to be substantially as wide as the width of the drive member boss 66.
  • the top surface 65 of the drive member flange portion 66 is coated with a layer of adhesive 68 which bonds directly to the abrasive grit 69 of the finishing article 62.
  • the adhesive need be only strong enough to secure the drive member 60 to the finishing article 62 for purposes of storage since, as indicated with respect to the structure of FIGS. 5 and 6, threading the finishing article onto a support pad of the type hereinbefore described results in a tenacious securement of the finishing article.
  • FIG. 8 there is illustrated still another alternative construction of a drive member 70 for securement to a finishing article 72.
  • the drive member 70 is mechanically fixed through an axially central opening 74 defined by the finishing article 72 by means of tabs 76 which are pressed into intimate integral gripping connection with the finishing article backing material 78.
  • the drive member 70 is formed with a boss 80 and an annular flange 82 radiating from the base of the boss 80 for disposition against the abrasive material side 84 of the finishing article 72.
  • the abrasive material 84 in the vicinity of the central opening 74 may be skived from the backing material 78 to provide a central cleared portion 86 to accommodate the flange 82.
  • the plurality of tabs 76 are punched through the flange 82 and extend upright therefrom annularly about the boss 80. The tabs 76 are formed suffciently close to the boss 80 so that they can be inserted through the finishing article opening 74 along with the boss 80.
  • the finishing article 72 is illustrated after insertion of the boss 80 and tabs 76 through the opening 74, and after the tabs 76 have been pressed into biting engagement with the backing material 78.
  • an annular member (not shown) is brought down onto the top surfaces 88 of the tabs 76 while the flange is disposed against a supporting anvil (not shown).
  • the tabs 76 are thus bent over into pressing engagement with the backing material 78 so as to bite into the backing material 78, thereby pinching or gripping the material between the tabs 76 and the adjacent portions of the flange 82 as shown at 90.
  • a strong mechanical connection is thus effected between the drive member 80 and the finishing article 72.
  • the fully constructed finishing article 72 can now be threaded onto a support pad such as is illustrated in FIG. 1.
  • FIG. 12 still another alternative manner of forming the outwardly extending member and tabs is illustrated.
  • the flange 92 is relieved or cut out at spaced portions 94 and 96 and the resultant material is bent upwardly to provide tabs 98 and 100 respectively. Any number of such cutouts and tabs may be provided and they may take any desired geometric form.
