FINISHING TOOL Filed April 22, 1968 2 Sheets-Sheet 2 IN VENTOR. JAMES H. (OUNTEYMflN United States Patent 0 3,606,709 FINISHING TOOL James H. Countryman, 3324 Trailon Road, Dayton, Ohio 45439 Filed Apr. 22, 1968, Ser. No. 722,885 Int. Cl. 323d 71/00; B24d 9/02 US. Cl. 51-375 24 Claims ABSTRACT OF THE DISCLOSURE Several abrading tool assemblies are disclosed each having a finishing shoe resiliently and detachably clipped onto a tubular holder.

This invention relates to a finishing tool and more particularly to a finishing tool usable in sanding or polishing automobile bodies or the like. As will become apparent the tool may be used in finishing substantially any metal, wood or plastic surface.

When finishing many types of surfaces, especially those having a substantial area, portions of which are planar or flat and other portions of which are curved or arcuate, it is difficult to be certain that a completely smooth surface is being formed. Thus, for example, when sanding an automobile body that has been filled with lead or a plastic composition, it is quite easy to apply too much pressure to the area being sanded with the result that that area is recessed below the surrounding areas. Frequently, only a small portion of an automobile body will require sanding but considerable care is required to obtain a smooth overall surface. For this reason various finishing tools have been designed which have a substantial surface area. One such tool is shaped as a cylinder of cardboard or heavy paper completely coated with grit or sand. This device has a drawback that once the grit or sand is worn away it cannot be reused. Also, in order to sand a small damaged area of, for example, an automobile body, it is very difficult to avoid sanding substantial surrounding areas which then will require further refinishing. Some sanding tools are designed with provision for replacing single sheets of sandpaper. Typically these have unreliable or elese expensive, complicated clamps for holding the sandpaper. One such tool is cylindrical in form but is made quite flexible and is therefore inappropriate for many finishing operations.

An object of this invention is to provide an improved finishing tool especially adapted for use in finishing relativelysmall portions of a larger surface, the major portion of the tool being indefinitely reusable. To this end, a generally'tubular holder is provided to which a finishing shoe is readily removably attached. The finishing shoe can either be formed of a finishing material or be covered by a finishing material. When the finishing material becomes clogged or worn through use it is discarded and easily replaced.

Another object of this invention is to provide a finishing tool assembly having an elongate holder and a plurality Of removable finishing shoes aligned thereon. In some embodiments, different ones of the finishing shoes may have diiterent types of finishing surfaces. In any event, large surface areas can easily be finished level without damage to the surrounding areas.

Another object of this invention is to provide a finishing tool having a holder to which may be clamped a variety of types of finishing shoes for working on various differently contoured surfaces. In accordance with this invention a single holder may be provided with a supply of different shapes of finishing shoes, each adapted for a special finishing operation.

Another object of this invention is to provide a finishing tool which can be either manipulated by hand or by conventional sanding machines or the like and which is adapted to perform not only sanding but polishing operations and the like. In accordance with this invention, the tool may be used with sheets of abrasive material such as sandpaper and with polishing cloths at the same time, whereby the surface portion to be sanded will be brought to a level with surrounding surfaces yet substantial surrounding areas will not be marred by sandpaper.

Other objects and advantages will become apparent from the following description and the drawing in which:

FIG. 11 is an end view of the embodiment of FIG. 10;

FIG. 12 schematically illustrates apparatus used in forming the finishing shoe of FIG. 10 and shows a portion of a finishing shoe as it would appear in a longitudinal section along the line 1212 of FIG. 10;

FIG. 13 is a partial perspective view illustrating a tool made in accordance with this invention manually used in the sanding of an automobile body; and

FIG. 14 is a perspective view illustrating the manner in which a finishing tool made in accordance with this invention may be attached to an air-operated reciprocating sander.

Referring to FIGS. 1, 2, 3 and 4, a first embodiment of a finishing tool, generally designated 10, is illustrated therein as comprising an elongate, generally tubular, thinwalled, hollow holder 12 and four identical abrasive forms or finishing shoes 14 mounted thereon in aligned end-toend relation with their confronting end surfaces coextensive. As shown best in FIGS. 2 and 3, the holder 12 is made from a single sheet of substantially rigid material, such as aluminum, which is either extruded or rolled into a cylindrical form such that the unstressed transverse cross section thereof is circular. The two circularly arcuate, convex side walls, designated 16 and 18, of the holder 12 have confronting edges 20 and 22, respectively, defining therebetween a longitudinal slit 24. Each side wall 16 and 18 is thus generally semi-circular and symmetrical with respect to a plane longitudinally separating them and passing vertically and centrally through the slit 24 as viewed in FIG. 2.

Each finishing shoe 14, as shown best in FIG. 4, comprises an elongate, generally U-shaped clip 26 of sheet material and a flexible, rectangular piece of finishing material 28 covering the outer surface of the clip 26. The piece of finishing material 28 may be a polishing cloth, sandpaper, emery cloth or the like. The longitudinally extending edges, designated 30, of the finishing material 28 are bent and folded over the longitudinally extending top margins of the clip 26. In transverse, section, the clip 26 is preferably shaped as an arc of a circle. It is made of the same material as the holder 12 and, prior to assembly, will have the same transverse internal and external radii as the side walls 16 and 18 of the holder 12.

Since both the holder 12 and the clips 26 are composed of a substantially rigid material, both have selfsupporting shapes. However, they are adequately resilient in view of the thickness thereof that the side walls 16 and '18 of the holder 12 will be compressed inwardly, narrowing the slit 24, and the opposed sides of each clip 26 will be forced slightly out of their circularly arcuate shape when the shoes 14 are pressed onto the holder 12. The folded edges of the sheet material 28 clamped between the clips 26 and the holder 12 will conform to the arcuate shapes thereof and, as a result, the opposed, concave inner surfaces of the finishing shoes 14 will firmly resiliently grip the holder 12. Also, the pieces of finishing material 28 are quite firmly clamped on the clips 26. The total circumference of each clip 26 is greater than 180 and there is no tendency for the clips 26 to be cammed off the holder 12 once they are pressed completely thereon.

The tool 10 of FIG. 1 is shown provided with a longitudinally extending handle 34 attached thereto by screws 36 and spaced above the holder 12 by spacers 38 surrounding the screws 36. The screws 36 are diametrically opposed to the slit 24 and pass through apertures in the holder 12. The handle 34 is, of course, assembled on the holder 12 before the shoes .14 are mounted thereon. This can easily be accomplished by passing a screw driver through the slit 24. When sanding or polishing, the tool 10 is moved back and forth with a reciprocating motion. Occasionally the tool 10 may be rolled about its axis to present fresh finishing material to the surface being finished or to reach various curved or grooved surfaces. The use of the tool 10 in sanding a contoured section of an automobile body 40 is illustrated in FIG. 13.

The spacing of the holes or apertures for receiving the screws 36 is desirably a standard spacing so that the holder 12 can also be mounted on conventional power operated sanding devices. For example, FIG. 14 shows a sanding devices 42 which is air-operated to reciprocably drive a carriage 44 thereon. The holder 12 in FIG. 14 is attached by screws 46 to the carriage 44. Only one of the screws 46 is visible in the perspective view of FIG. 14.

As apparent, the sheet material 28, once worn out, can easily be replaced simply by manually removing the shoes 14 from the holder 12 and folding freshsheets thereon. Also, all of the shoes need not be covered by the same type of finishing cloths or sheets. For example, referring to FIG. 1, the central shoe 14 could have a sandpaper surface and the two outer shoes a polishing cloth surface. Such a construction is valuable in sanding or finishing small areas of, for example, an automobile body where it is desired that the areas being worked upon are level with the surrounding areas yet sanding of the surrounding areas would be undesirable. Of course, it would be possible to use all different grades of sandpaper and other finishing materials on the clips 26 to form the finishing shoes 14. As a convenience, each of the clips 26 may be proportioned to receive exactly onefourth or one-half of a sheet of conventional size sandpaper so that no sandpaper will be wasted in assembling or reassembling the tool of FIGS. 1 through 4. It is to be understood, however, that both the holder 12 and theshoes 14 could have lengths different from that illustrated.

In FIG. a finishing tool, generally designated 48, is shown which may be useful in finishing small surface areas. The tool 48 includes a holder 50 which is a short, thin-walled tubular band of cylindrical, sheet material. Except for its length, the tool 48 may be substantially identical to the holder 12 and is provided with 4 a slot designated 51 so that the sides thereof can be resiliently forced inwardly to receive a finishing shoe 14 identical to any of the finishing shoes 14 of FIGS. 1 through 4.

As previously mentioned, the holder 12 of FIG. 1 and the holder of FIG. 5 are circular in transverse cross section and the shoe 14 has circular inner and outer surfaces extending through slightly more than 180. The circular construction of the confronting surfaces of the holders and the shoes is desirable to achieve 'a firm clamp on the sheet of finishing material 28 and a firm grip of the shoes 14 on the holders 12 and 50 of FIGS. 1 through 4 and FIG. 5, respectively. However, the remaining surface portions of the surface of the holder and shoes need not necessarily be circular. Another embodiment of the invention employing the same principles is shown in FIGS. 6 and 7. The tool in FIGS. 6 and 7, designated 52, comprises a holder 54 and one or more shoes 56 received thereon. The holder 54 has circular sides 58 with confronting edges 60 defining a longitudinally extending slot therebetween as in the case of the holder 12 of the embodimentof FIGS. 1 through 4. However, in the embodiment of FIGS. 6 and 7, the holder 54 has a flat or just slightly curved top plate portion 62. The sheet material forming the holder joining the sides 58 and the top plate portion 62 are bent to form abutments or flanges 64 along the top edges of the sides 58 against which the longitudinally extending top margins of the shoes 56 are abutted. The abutments 64 thus serve to maintain an alignmentof the shoes 56 such that their confronting edges are coextensive when mounted on the holder 54.

The finishing shoes 56 in the embodiment of FIGS. 6 and 7 include a clip 66 which again may be formed of the same material as the holder 54 and which has circular sides, designated 68, but has a non-circular, generally V-shaped bottom portion 70 adjoining the side portions 68 thereof. Each shoe 5 6 finally includes a piece of flexible finishing material 28 identical to that used in FIGS. 1 through 4 and FIG. 5. Of course, in FIG. 7, the piece 28 will conform to the shape of the clip 66 and its bottom surface, therefore, will be less rounded. The tool 52 of FIGS. 6 and 7, accordingly, can be used when finishing more sharply contoured surface areas than can the tool of FIGS. 1 through 4 orthe tool of FIG. 5. However, it should be noted that the shoes 56 of FIGS. 6 and 7 could be used with the holder 12 in the embodiment of FIGS. 1 through 4 or the holder 50 in the em.- bodiment of FIG. 5 and it is contemplated that one holder, say,-eitherthe holder 12 of FIG. l through 4,, or the holder 54 of FIGS. 6 and 7, could be sold with different sets of shoes such as the shoes 14 andthe shoes 56. No handle is shown in FIGS. 6 and .7, but it will. be understood that the tool 52 could be attached to a handle or a power tool similar to the device 42. For this purpose, spaced holes72 (only one being visiblein FIG. 6) are provided. 1

Further to illustrate the variety of shoes whichmay be used with the tools made in accordance with this invention, FIG. '9 shows the same holder 54 showrr in FIGS. 6 and 7 but provided with a shoe'74 having circular sides but a more rounded or oval bottom portion covering the slot between the confronting edges 60 of the sides 58 of the holder. With the construction of FIG..9,of course, the sheet of finishing material applied to a surface would more easily finish a wider surface area than would the shoes of the previously described embodiment.

In each of the preceding embodiments, the cliptpart of the finishing shoe is of the same material and wall thickness as the holder. Both are manufactured from a relatively rigid material, such as aluminum, and, when assembled, the tools are quite rigid. In FIG. 8, a finishing tool 76 is illustrated having an elongate holder-78 of sheet material and an elongate finishing shoe. 80 including an outer lining or piece of finishing material 82 which may be identical to the previously described pieces of finishing material 28. FIG. 8 shows the tool 76 in transverse cross section and it is tobe understood that the holder 78- is sufficiently long to receive several shoes 80. The clip 84 of the shoe 80 of FIG. 8 is made of a resilient or pliable plastic such as a rubberized polyvinyl chloride extruded in the shape illustrated in FIG. 8 having an arcuate, thin-walled upper wall 86 and an arcuate, thin-walled lower wall 88 joined along their top edges to form side wall members 90. The side members 90 are wedge-shaped in transverse cross section and considerably thicker than either of the walls 86 and '88. The pliable plastic is sufficiently stiff to render the shape illustrated in FIG. 8 self-supporting and to resist further separation of the side members 90. Therefore, when assembled, the shoe 80 resiliently grips the sides of the holder 78. The upper wall 86 and the side members 90 have a common, concave and circular exposed, upper surface 92. The radius of the surface 92, designated by the dash line a, is the same as the unstressed radius of the sides of the holder 78 and shorter than the radius b of the upper surface 94 of the lower wall 88. The two radii a and b are struck on spaced parallel and longitudinally extending centers with the center of radius a being higher or further from the lower wall 88 than the center of the radius 11 so that both walls 86 and 88, in transverse section, are U-shaped and circular yet spaced throughout a major portion of the length thereof, with an air channel 96 being formed therebetween. The ends of the clip- 84 are open so that no air is trapped in the channel 96'.

The resilient or pliable nature of the material from which the clip 84 is made renders the lower wall 88 sufficiently flexible that it conforms to the surface being sanded when pressure is applied thereto. The shoe 80 of FIG. 8 is especially adaptable for final finishing operations requiring wet sandpaper, but, of course, could be used with dry sandpaper or other finishing materials. Because of the flexibility of the lower wall 88, wet sandpaper is less likely to be ripped than in those tools wherein the outer surface of the finishing shoe clip is more rigid.

Further in connection with FIG. 8 it will be noted that the top surface of the holder 78 has outwardly extending, solid side flanges or ledges 98 integral with the rest of the holder. The side flanges or ledges 98- serve as abutments to align several shoes 80 on the holder 78. Because the flanges 98 are solid, the holder 78 could not be formed from flat sheet material but would preferably be extruded. A captive screw 100 is illustrated in FIG. 8 projecting through an aperture 102 in the top of the holder 78. Two such screws 100 are used for attachment to a handle (not shown) or to a power operated sanding device such as the device 42 shown in FIG. 14 in procisely the same manner described above. It will be appreciated that the dimensions of the holder 78 of FIG. 8 could be the same as that of FIG. 1 so that the various finishing shoes illustrated herein could be used therewith. Of course, in such event, the finishing shoe 80 would have a larger external finishing surface than the other finishing shoes illustrated in FIGS. 1, 6 and 9.

' Referring now to: FIGS. 10, 11 and 12, a finishing tool 104 is illustrated therein including a holder 6 of a construction substantially identical to the holder 54 illustrated in FIGS. 6, 7 and 9. The top surface of the holder 106 has a pair of apertures therein, one of which is illustrated at 108, for attachment of the holder-to a handle or a power operated sanding tool. The primary difference between the tool 104 and the tools previously described is in the construction of the shoes, designated 110, each of which is made from a single rectangular piece of spring steel having a plurality of apertures 112 partially punched through its surface. The apertures 1 12 have been punched downwardly, forcing the ruptured or struck metal from each of the apertures outwardly of the holder 106 to form a plurality of teeth 114. As ap parent from FlGS. l0 and 12 the teeth 114 lie in longitudinally extending rows and are struck from the spring metal of the shoe to project at an acute angle downwardly from the outer surface of the shoe 110. Each tooth desirably lies in the same acute angle with respect to the outer surface of the shoe 110 but all adjacent teeth in each of the longitudinal rows thereof project in opposite directions along the rows.

The tool 104 is a special purpose tool designed for crude finishing operations requiring a highly abrasive surface and especially for the initial finishing of surfaces filled with two-part epoxy or similar fillers. After the surface to be refinished has been filled and while the filler is still pliable before fully cured or hardened, the tool 104 can be wiped thereacross to remove excess filler material. The tool 104 is wiped in reciprocal endwise strokes. During a stroke in one direction the filler material will be scooped by the teeth 114 projecting in that same direction through corresponding apertures 112 and into the open space 116 inside to tool 104. Of course, during a stroke in the opposite direction the other teeth 114 will now be active to scoop the filler material into the space 116. Depending upon the character of the surface being finished, the alternate teeth 114 which are not cutting into the surface during a stroke in a given direction may be sharpened by being abrasively rubbed across the surface.

The one-piece shoe 110 could have various shapes such as the U-shaped shown in FIGS. 17 and 9. The specific U-shape illustrated in FIGS. 10 and 11 is, however, preferred for removing excess filler material from rather large surface areas. Referring to FIG. 11, which shows an end view of the tool 104, the shoe 110 includes circular side portions 118 resiliently gripping the circular sides of the holder 106. As in the previously described embodiments, the radius of the circular, external side surface of the holder 106 may be the same as the radius of the internal surfaces of the shoe sides 118 before the parts are assembled together. The shoe 110 is curved convexly outwardly to each side as indicated at 120 beneath the circular sides 118. The outwardly curved portions 120 are connected by a rather wide bottom plate portion 122. The plate portion 122 may be planar or, as illustrated, slightly arcuate.

FIG. 12 schematically illustrates a plurality of punches cooperating with a die plate 132 used in forming the teeth 114. It will be observed that the cooperating surfaces of the punches 130 and the depressions in the die plate 132 are such that the teeth 114 taper to a sharp outermost edge. The longitudinally extending rows of teeth as viewed in FIG. 10 and 11 need not be struck out of the entire surface of the shoe 110 but desirably would be struck from the entire bottom plate portion 122 and at least part of the lower convexly curved outer sides 120. The rows of teeth 114 would preferably be formed with the spring steel of the shoe 110 laid flat. Thereafter the spring steel is suittably tempered so that the shape illustrated in FIGS. 10 and 11 is selfsupporting. The same, of course, would be true if the shoe 110 were made into any of the shapes illustrated in FIGS. 1 through 7 and 9.

The spring steel shoe 110 will not have the rigidity of an aluminum shoe or of the side wallportions 86- and 88 of the plastic shoe 80 of FIG. 8. Therefore, the inherent resiliency of the holder 106 and the shoe 110 may not be adequate to retain the shoe 110 on the holder 106. To better retain the shoe 110 in place, a plurality of protuberances 124 may be punched outwardly from the metal forming the holder 106 just below the side flanges or abutments, designated 126, thereof. The protuberances 124 cooperate with mating apertures 128 in the shoes 110 to align as well as retain shoes 110 on the holder 106.

If it is desired to make all of the various shoes illustrated herein interchangeably usable with the various holders illustrated herein, all of the holders could be provided with protuberances similar to the protuberances 124 and all of the various shoes could be provided with apertures corresponding to the apertures 128. However, such protuberances and apertures would not be required in the tools illustrated in FIGS. 1 to 9 because shoes and holders thereof are sufiiciently rigid to render such protuberances and apertures unnecessary. Also, it will be appreciated that shoes similar to the shoe 110 may be made sufficiently stiff that the protuberances 124 may be unnecessary even for use with such a shoe. Further, conventional, but suitably formed, punched or perforated abrasive sheets could be clipped to the holder 106 in lieu of the special purpose shoe 110 described above.

Although the presently preferred embodiments of this invention have been described, it will be understood that various changes may be made within the scope of the appended claims.
