Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to radius and angle dressers and more particularly pertains to a new quick set radius dresser for making a dressing radius on grinding wheels faster and easier. 
     2. Description of the Prior Art 
     The use of radius and angle dressers is known in the prior art. More specifically, radius and angle dressers heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     Known prior art dressers include U.S. Pat. No. 4,180,046; U.S. Pat. No. 4,274,231; U.S. Pat. No. 5,038,746; U.S. Pat. No. 5,003,730; U.S. Pat. No. 4,299,196; and U.S. Pat. No. 4,073,281. 
     In these respects, the quick set radius dresser according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of making a dressing radius on grinding wheels faster and easier. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of radius and angle dressers now present in the prior art, the present invention provides a new quick set radius dresser construction wherein the same can be utilized for making a dressing radius on grinding wheels faster and easier. 
     The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new quick set radius dresser apparatus and method which has many of the advantages of the radius and angle dressers mentioned heretofore and many novel features that result in a new quick set radius dresser which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art radius and angle dressers, either alone or in any combination thereof. 
     To attain this, the present invention generally comprises a magnet base having a cylindrical configuration with a circular top face, a circular bottom face, and a periphery formed therebetween. The top face has a threaded bore formed in a central extent thereof. A lever is positioned on the periphery with a first orientation for effecting the magnetization of the bottom face of the magnet base. With the lever in the first orientation, the magnet base is adapted for securing with a metallic recipient surface. In its second orientation, the magnet base serves for demagnetizing the magnet base for allowing the removal thereof from the recipient surface. Also included is a spacer having a cylindrical configuration with a circular top face, a circular bottom face, and a periphery formed therebetween with a diameter less than that of the magnet base. The bottom face has a rectilinear recess for receiving a top extent of a plug having a rectilinear configuration. As shown in FIG. 1, the plug includes a bottom extent having a bolt extending downwardly from the spacer in concentric relationship therewith. This is for screwably coupling with the threaded bore of the magnet base. The spacer further having a central conduit extending between the top face of the spacer and a top surface of the top extent of the plug. For reasons that will soon become apparent, the top face of the plug has a threaded aperture formed therein. Next provided is a handle ring having a cylindrical configuration. Similar to the forgoing components, the handle ring has a circular top face, a circular bottom face, and a periphery formed therebetween with a diameter less than that of the magnet base. The periphery of the handle ring is knurled. The top face of the handle ring has a cylindrical recess formed in a central extent thereof which communicates with a central hole formed through the entire handle ring and has a diameter less than that of the cylindrical recess. A radially extending linear recess is formed between the cylindrical recess and the periphery of the handle ring. A pair of flanking threaded apertures are formed adjacent a periphery of the handle ring at a midpoint of the linear recess. As such, a bolt extends through the central hole of the handle ring and the central conduit of the spacer for screwably engaging with the threaded aperture of the top extent of the plug thereof. As best shown in FIG. 3, an adjustable platform is provided including a horizontal plate. The horizontal plate has a guide post formed on a lower surface thereof which extends downwardly therefrom for slidably engaging the linear recess of the handle ring. A pair of parallel guide slots are formed adjacent opposite side edges of the plate. It is through such guide slots that a pair of retaining bolts pass prior to engaging the flanking threaded apertures of the handle ring. By this structure, the adjustable platform is adapted to slide along a radius of the top face of the handle ring and is further selectively fixed in place by way of the retaining bolts. Mounted on a top surface of the adjustable platform is a diamond holder block. The block has a cutting tip extending from an inboard face thereof and extending in parallel relationship with the radius of the top face of the handle ring. Finally, a gauge pin has an upper portion with a cylindrical configuration, a first diameter, and a first length. Associated therewith is a lower portion with a cylindrical configuration, a second diameter less than the first diameter and equal to the diameter of the cylindrical recess of the handle ring, and a second length less than the first length. The upper portion has a semi-cylindrical cut out formed therein with a length half the first length. 
     There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new quick set radius dresser embodying the principles and concepts of the present invention and generally designated. by the reference numeral 10 will be described. 
     The present invention, designated as numeral 10, includes a magnet base 12 having a cylindrical configuration with a circular top face, a circular bottom face, and a periphery formed therebetween. The top face has a threaded bore 14 formed in a central extent thereof. A lever 16 is positioned on the periphery with a first orientation for effecting the magnetization of the bottom face of the magnet base. With the lever in the first orientation, the magnet base is adapted for securing with a metallic recipient surface 18 adjacent a grinding wheel. In its second orientation, the magnet base serves for demagnetizing the magnet base for allowing the removal thereof from the recipient surface. To accomplish this, an electromagnet or a movable high intensity magnet may be employed. 
     Also included is a spacer 20 having a cylindrical configuration with a circular top face, a circular bottom face, and a periphery formed therebetween with a diameter less than that of the magnet base. The bottom face has a rectilinear recess 22 for receiving a top extent of a plug 24 having a rectilinear configuration. As shown in FIG. 1, the plug includes a bottom extent having a bolt extending downwardly from the spacer in concentric relationship therewith. This is for screwably coupling with the threaded bore of the magnet base. The spacer further having a central conduit 26 extending between the top face of the spacer and a top surface of the top extent of the plug. For reasons that will soon become apparent, the top face of the plug has a threaded aperture 28 formed therein. 
     Next provided is a handle ring 30 having a cylindrical configuration. Similar to the forgoing components, the handle ring has a circular top face, a circular bottom face, and a periphery formed therebetween. The periphery of the handle ring is knurled. The top face of the handle ring has a cylindrical recess 32 formed in a central extent thereof which communicates with a central hole 34 formed through the entire handle ring and has a diameter less than that of the cylindrical recess. 
     A radially extending linear recess 36 is formed on the top face of the handle ring between the cylindrical recess and the periphery. A pair of flanking threaded apertures 40 are formed adjacent a periphery of the handle ring at a midpoint of the linear recess. As such, a bolt 42 extends through the central hole of the handle ring and the central conduit of the spacer for screwably engaging with the threaded aperture of the top extent of the plug. 
     As best shown in FIG. 3, an adjustable platform 44 is provided including a horizontal plate. The horizontal plate has a guide post 46 formed on a lower surface thereof which extends downwardly therefrom for slidably engaging the linear recess of the handle ring. A pair of parallel guide slots 48 are formed adjacent opposite side edges of the plate. It is through such guide slots that a pair of retaining bolts 50 pass prior to engaging the flanking threaded apertures of the handle ring. By this structure, the adjustable platform is adapted to slide along a radius of the top face of the handle ring and is further selectively fixed in place by way of the retaining bolts. 
     Mounted on a top surface of the adjustable platform is a diamond holder block 52. The block has a cutting tip 54 extending from an inboard face thereof and extended in parallel relationship with the radius of the top face of the handle ring. 
     Finally, a gauge pin 56 has an upper portion 58 with a cylindrical configuration, a first diameter, and a first length. Associated therewith is a lower portion 60 with a cylindrical configuration, a second diameter less than the first diameter and equal to the diameter of the cylindrical recess of the handle ring, and a second length less than the first length. The upper portion has a semi-cylindrical cut out 62 formed therein with a length half the first length. 
     In operation, the user first sets the radius of the unit with the gauge pin. The unit is then positioned on the internal grinder or related machine and secured in place by turning the lever on its magnet. The grinding wheel could then be fed past its diamond nib, thereby dressing it. The present invention possesses a high degree of accuracy thus improving the dimensional accuracy of the wheels that it would be used to dress. Further, it is capable of a small compact size for easy storage. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
