2. Description of the Prior Art It is known to attach or connect abrasives directly to a holder, in various fashions and ways; namely, by gluing the abrasive directly onto a holder. However, applicants innovation is in applying a layer of resilient material between the abrasive and the tool to absorb shock and reduce chatter.
SUMMARY OF THE INVENTION According to the invention, the resilient material is applied either directly between the abrasive and abrasive holder, or between the abrasive holder and the expander plate, or between the expander plate and the cone means, or any combination thereof, for the purpose of reducing shock and chatter.

FIG. 5A is a partial cross-sectional end view of FIG. 5.
FIG. 6 is a partial cross-sectional view of another preferred embodiment.
FIG. 6A is a partial cross-sectional end view of FIG. 6.
FIG. 7 and FIG. 7A show an abrasive holder having a layer of resilient material on the bottom surface thereof.
FIG. 8 shows a cross-sectional view of a honing tool with the cone rod pushing to expand the honing abrasives.
DESCRIPTION OF THE PREFERRED EMBODIMENTS The honing tool, in FIG. 1 and 1A generally indicated at 11, comprises a honing tool body 13, with a guides attached thereto by conventional screws 16.
The body 13 comprises an axial bore 17 and circumferentially spaced slots 19. A cone means 21 is slidably movable within the bore 17 thereby providing radial movement of the abrasive means 23.
The abrasive means comprises an expander plate 25, which is adapted to be moved by cone means 21, by virtue of axial movement of thecone means thereby providing contacting bevelled surface 22 of the cone means 21 to contact edge 25 on expander plate 25. The abrasive means 23 is restrained in its normal radial position by garter springs 27 and 28 which encircle the honing tool body holding the abrasive means.
The springs 27 and 28 are seated in recess 29 and 30 respectively, of abrasive holder 33 in order to prevent the abrasive holders from falling out of the slots 19. The abrasiveholder 33 comprises an abrasive 35 applied to a resilient material 39, such as epoxy, urethane, cement, cork, neoprene, or synthetic substance. The resilient material reduces shock and prevents or decreases chatter, when the honing tool is reciprocated and rotated with surface 36 of the abrasive pressed against-the surface of a workpiece for abrading purposes.
FIG. 2 and 2A show a modification, in whichthe basic parts of the tool are the same, however, the modification will be FIG. 5 and FIG. 5A show another embodiment in which the resilient layer 43 is applied to the surface of the cone 21 FIG. 6. and 6A show another embodiment in which the abrasive holder 33' is made of resilient material to reduce chatter and shock when used in honing and abrading applications.
FIG. 7 and FIG. 7A show a modified abrasive holder 53 with a layer of resilient material 40 attached to the bottom surface thereof.
FIG. 8 shows a final embodiment with a cone rod 47 having the resilient material 44 applied between the cone rod 47 and the cone .21. This embodiment covers the tool in which pressure is applied in a pushing direction against the cone means to expand the honing stones.
It is to be understood that besides the independent use of the resilient material, of the plastic or epoxy layer, it is conceivable and apparent that combinations of its use are advantageous. For example, an epoxy abrasive holder combined with a layer of epoxy applied also to the surface of the cone would reduce chatter and shock and still maintain normal honing characteristics.
