Portable power driven scarifying tool for pipe ends

Abstract

A small transmission that has wired brushes attached to the gears ( 2 ) and ( 3 ). One of the gear/wire brush ( 2 ) has an extended shaft to receive a drill motor. Housing ( 1 ) is coupled with two closures ( 4 ) & ( 5 ) to incase the gears, and to harness the shafts. The bushings ( 6 ) combined with the bushing bolts ( 7 ) so that the top end of the transmission is secured. The right closure bolt/arresting rod ( 8 ), and a left closure ( 9 ) bolt are combined to secure the bottom of the transmission. A crank ( 11 ) is attached to a cranking gear shaft ( 10 ).

We claim:  
     
         1 . This scarifying devise for cleaning pipe ends and pipe fittings is a transmission comprising of: 
 a. A housing that is made of plastic or metal that secure gears.    b. The gears having shafts through the center.    c. The gears are contiguous to each other.    d. The closures made of plastic or metal, that sandwich these gears into the housing and maintain the shafts ninety-degree angle to the tool.    e. Two of these shafts having wire tube brushes attached to them.    f. The third shaft having a crank attached to it for manual use.    g. The two tube wire brushes are flanked by bushings on each side.    h. The bushings and the closures are held together by the bushing bolts.    i. These bushing bolts also hold the closures onto the housing at the top end of the tool.    j. The bottom of the left side of the tool is held together by the left closure bolt/rotation arresting rod.    k. The bottom of the right side of the tool is held together by the right closure bolt/rotation arresting rod.    l. The closure bolt/rotation arresting rod, when resting on the operators forearm or against the drill motor handle, stops the tool from rotating.    
     
     
         2 . This scarifying devise for cleaning pipe ends and pipe fitting is a transmission comprising of: 
 a. A housing that is made of plastic or metal that secure pulleys and belts.    b. The pulleys having a shafts through the center.    c. The pulleys are contiguous to one another by a belt or belts.    d. The closures made of plastic or metal sandwich these pulleys into the housing and maintain the shafts ninety-degree angle to the tool.    e. Two of these shafts having wire tub brushes attached to them.    f. The third shaft having a crank attached to it for manual use.    g. The two tube wire brushes are flanked by bushings on each side.    h. The bushings and the closures are held together by the bushing bolts.    i. These bushing bolts also hold the closures onto the housing at the top end of the tool.    j. The bottom of the left side of the tool is held together by the left closure bolt/rotation arresting rod.    k. The bottom of the right side of the tool is held together by the right closure bolt/rotation arresting rod.    l. The closure bolt/rotation arresting rod, when resting on the operators forearm or against the drill motor handle, stops the tool from rotating.    
     
     
         3 . This scarifying devise for cleaning pipe ends and pipe fittings is a transmission/motor comprising of: 
 a. The transmission configuration that is said to be the the same as  claim 1  and or  2 .    b. The closure bolt/rotation arresting rod, is directly bolted to a motor, thereby arresting the rotation of the tool.
