Screw jack socket

Abstract

A tube having notches in the lower end and a solid cap at its upper end. The tube is empty. A drill bit is mounted in the upper end and extends to the exterior. In one form, the tube, with the cap, is an integral, one-piece molded item, and the drill bit is steel; in another form, the cap, while being plastic, is glued on the tube.

1 . A screw jack socket comprising, 
 a tube having a lower end and an upper end,    the lower end having an end surface lying in a plane perpendicular to the longitudinal axis of the tube, and a pair of notches therein extending longitudinally and lying on a single diametrical line,    the upper end including a cap sealing the tube from the exterior except through the notches, and a drill bit embedded in the cap and extending upwardly therefrom beyond the cap enabling operable engagement therewith by a drill.    
   
   
       2 . A screw jack socket according to  claim 1  wherein, 
 the tube and cap are constituted by a single, integral article of molded plastic.    
   
   
       3 . A screw jack socket according to  claim 2  wherein the drill bit is made of steel.  
   
   
       4 . A screw jack socket according to  claim 3  wherein, 
 the tube from the cap through the lower end, is entirely hollow without protuberances and obstructing elements.    
   
   
       5 . A screw jack socket according to  claim 1  wherein, 
 the cap is separate from the tube, and includes a top element and a longitudinal surrounding skirt surrounding the tube, and    the cap is secured to the tube by glue.    
   
   
       6 . A method of using a screw jack socket, in connection with scaffolding that includes vertical structural legs and screw jacks detachably fitted in the lower ends of the legs for enabling vertical adjustment of the legs to move the lower ends of the legs into a common horizontal plane, 
 the screw jacks having narrow up-standing stems,    the socket including a hollow interior capable of receiving the stems thereinto, selectively, and operating the socket until the respective jack is at the desired height.
