Apparatus for Successively Cutting and Driving a Shaft

Abstract

A shaft driving tool incorporating a cylindrical body having an upper end and having a vertically extending hollow bore, the vertically extending hollow bore having a wall; female helical threads fixedly attached to the wall of the vertically extending hollow bore; a helically threaded screw shaft received within the vertically extending hollow bore, the helically threaded screw shaft having a shaft engaging lower end and having an upper end; shaft hub clamping set screws fixedly attached to the cylindrical body, the shaft screw clamping set screws being positioned at a lower end of the cylindrical body; and a drill or socket driver adapter fixedly attached to or formed wholly with an upper end of the helically threaded screw shaft, the drill or socket driver adapter extending upwardly from the helically threaded screw shaft.

The invention hereby claimed is: 
     
         1 . A shaft driving tool comprising:
 (a) a cylindrical body having an upper end and having a vertically extending hollow bore, said bore having a wall;   (b) female helical threads fixedly attached to or formed wholly with the wall of the vertically extending hollow bore;   (c) a helically threaded screw shaft received within the vertically extending hollow bore, said screw shaft having a shaft engaging lower end and having an upper end;   (d) shaft hub clamping means fixedly attached to the cylindrical body, said means being positioned at a lower end of said body; and   (e) a drill or socket driver adapter fixedly attached to or formed wholly with an upper end of the helically threaded screw shaft, said adapter extending upwardly from said end.   
     
     
         2 . The shaft driving tool of  claim 1  wherein the drill or socket driver adapter is hexagonal. 
     
     
         3 . The shaft driving tool of  claim 2  wherein the drill or socket driver adapter has a diameter, wherein the helically threaded screw shaft has a diameter, and wherein the diameter of the drill or socket driver adapter is less than the diameter of the helically threaded screw shaft. 
     
     
         4 . The shaft driving tool of  claim 3  further comprising a first plurality of wrench jaw engaging lands fixedly attached to or formed wholly with the helically threaded screw shaft, said lands underlying the drill or socket driver adapter, said lands overlying the upper end of the cylindrical body. 
     
     
         5 . The shaft driving tool of  claim 4  wherein the first plurality of wrench jaw engaging lands comprises a first set of six hexagonally arranged lands. 
     
     
         6 . The shaft driving tool of  claim 5  wherein the first set of six hexagonally arranged lands has a diameter greater than the diameter of the helically threaded screw shaft. 
     
     
         7 . The shaft driving tool of  claim 6  further comprising a second plurality of wrench jaw engaging lands, said lands being fixedly attached to or formed wholly with the cylindrical body. 
     
     
         8 . The shaft driving tool of  claim 7  further comprising a collar surrounding the helically threaded screw shaft, the collar being fixedly attached to or formed wholly with the cylindrical body, wherein the second plurality of wrench jaw engaging lands are positioned at said collar. 
     
     
         9 . The shaft driving tool of  claim 8  wherein the second plurality of wrench jaw engaging lands comprise a second set of six hexagonally arranged lands. 
     
     
         10 . The shaft driving tool of  claim 2  further comprising a lock channel extending circumferentially about the drill or socket driver adapter.
