Rotary buffer

Abstract

A rotary buffer for buffing and polishing concave surfaces. The rotary buffer includes a malleable cone, a cone shaft, and a mounting shaft. The mounting shaft is configured to be received in a chuck of a rotary power tool. The cone and cone shaft work in conjunction with one another to absorb impact from a surface being buffed and polished and to prevent the rotary buffer from bouncing.

1 . A rotary buffer comprising:
 a first assembly having a first shaft and a head, the first shaft configured to be received in a chuck of a power tool;   a second assembly coupled to the head, the second assembly having a base and a second shaft;   a cone coupled to the base and supported by the second shaft; and   a buffing pad coupled to the cone.   
   
   
       2 . The rotary buffer of  claim 1  wherein the cone is constructed of urethane foam. 
   
   
       3 . The rotary buffer of  claim 1  wherein the cone has a Durometer density of 30-45. 
   
   
       4 . The rotary buffer of  claim 1  wherein the cone absorbs an impact from a surface being buffed. 
   
   
       5 . The rotary buffer of  claim 1  wherein the second shaft reduces a deformation of the cone when a force is applied to the cone. 
   
   
       6 . The rotary buffer of  claim 1  wherein the second shaft reduces a stress on an adhesion point of the cone and the base when a force is applied to the cone. 
   
   
       7 . The rotary buffer of  claim 1  wherein the rotary buffer rotates at a speed of 100 to 2500 rotations per minute. 
   
   
       8 . The rotary buffer of  claim 1  wherein the buffing pad is constructed of at least one of twisted wool, natural lambs wool, wool blends, synthetic blends, wool silk blends microfiber, and fiberal wool felt blends. 
   
   
       9 . The rotary buffer of  claim 1  wherein the second shaft is tapered. 
   
   
       10 . The rotary buffer of  claim 1  wherein the first assembly is constructed of steel. 
   
   
       11 . The rotarty buffer of  claim 1  wherein the second assembly is constructed of polypropylene and is over-molded over portions of the first assembly. 
   
   
       12 . A buffer for buffing concave surfaces, the buffer comprising:
 a cone;   a buffing pad coupled to the cone and configured to contact a concave surface to be buffed;   a mount adapted to receive the cone, the mount including a first shaft configured to support the cone and adapted to reduce stress at an adhesion point; and   a second shaft coupled to the first shaft and adapted for insertion into a rotary device.   
   
   
       13 . The buffer of  claim 12  wherein the cone is adapted to absorb impacts from the concave surface and prevent the buffer from bouncing. 
   
   
       14 . The buffer of  claim 12  wherein the first shaft is tapered. 
   
   
       15 . A method of constructing a rotary buffer, the method comprising:
 machining a first base including a first shaft and a head;   overmolding a mount onto the head, the mount including a second base and a second shaft;   curing a cone onto the mount;   sewing a buffing material into a backing material to form a buffing pad; and   gluing the buffing pad to the cone.   
   
   
       16 . The method of  claim 15  wherein the cone is constructed of urethane foam. 
   
   
       17 . The method of  claim 15  and further comprising suspending the second shaft in a liquid urethane foam. 
   
   
       18 . A power tool comprising:
 a chuck;   a handle;   a rotary driver adapted to translate a received energy into a rotational force at the chuck; and   a rotary buffer including
 a first assembly having a first shaft and a head, the first shaft configured to be received in the chuck, 
 a second assembly coupled to the head, the second assembly having a base and a second shaft, 
 a cone coupled to the base and supported by the second shaft, and 
 a buffing pad coupled to the cone. 
   
   
   
       19 . The power tool of  claim 18  wherein the cone is adapted to absorb impacts from the concave surface and prevent the buffer from bouncing. 
   
   
       20 . The power tool of  claim 18  wherein the second shaft reduces a deformation of the cone when a force is applied to the cone. 
   
   
       21 . The power tool of  claim 18  wherein the second shaft reduces a stress on an adhesion point of the cone and the base when a force is applied to the cone.
