BACKGROUND—FIELD OF INVENTION




In the construction of commercial and residential structures with plywood or siding on walls and plywood on the roof. It is a common occurrence for nails that were intended to secure these materials to wood members to miss their intended target.




Depending on the size of the structure, these nails can occur at any height through roof plywood as well as in tall walls.




Often these nails are at precarious angles with little or no room for conventional tools to access them.




BRIEF SUMMARY OF THE INVENTION




The spring loaded nail remover has the capability of hooking those nails which are angled steeply or so close to a wood member that a gap needs to be created in order for the spring loaded nail remover to engulf the nail in its cylinder.




The spring loaded nail remover then manually punches out the nail allowing for final extraction from the opposing side of the plywood or siding.




The spring loaded nail remover can be mounted on any length 2×4 (depending on height of the nail) mounted vertically for nails through the roof plywood or horizontally for nail through wall plywood or siding.

DETAILED DESCRIPTION OF THE INVENTION




Description

FIGS. 1

,


2


,


3


and

FIG. 1

, the spring loaded nail remover being 14 inches in total length. With its novel features the utility compression spring


4


, retainer pin


7


and gapping hook


1


.





FIGS. 2

,


3


shows a steel piston is welded


11


cantilevered, on the mounting bracket


5


. The utility compression spring


4


, inserts over the steel piston


3


.





FIG. 3

, shows the cylinder


2


, inserted over the piston


3


. Drilled into the end of the piston a cone shaped indentation


10


.





FIGS. 2

,


7


shows the retaining pin inserted into the piston through a slot


8


, cut in the metal cylinder


2


, thus securing the spring


4


.





FIG. 4

, a gapping hook shaped and beveled


1


, (

FIG. 3

) welded on the metal cylinder


2


. Winged screws are threaded


6


, into the mounting bracket to secure the spring loaded nail remover to a 2×4 any length board. A beveled edge


9


, is ground out of the cylinder end


2


, to ease access to nails with zero clearance between a nail and wood member.




Operation





FIG. 5

, mounted on the 2×4 lumber


12


, by means of the mounting bracket


5


with a longitudinal channel and winged screws


6


, the gapping hook


1


, can be maneuvered into position between the nail


16


and the wood member


13


or elongated member. Then by twisting the spring loaded nail remover


14


, the nail is accessible


16


(FIG.


6


).





FIG. 6

, insert the cylinder


2


, over the nail


16


, until it meets the surface


15


. The nail inserts into the cone shaped piston end


10


.





FIG. 7

, manually compress the spring


4


, the retaining pin


7


, slides up the slot in the cylinder


8


, (

FIG. 2

) until the piston


3


, meets the surface


15


, forcing the nail upwards where it awaits final extraction


16


.



Claims
  • 1. A nail extracting apparatus comprising:a mounting bracket with a longitudinal channel which is a means for horizontal and vertical attachment to an elongated member, and a cantilevered piston attached atop said longitudinal channel of said mounting bracket, and a cone shaped indentation in a free end of said cantilevered piston end, a open ended cylinder having with a longitudinal slot with ends; means for sliding said cylinder in a longitudinal direction an extended and between a retracted position at which said cone shaped end of said piston terminates at one of the ends of said slot; a compression spring disposed between said mounting bracket and said cylinder to, and a hook means.
  • 2. The nail extracting apparatus of claim 1, where in said mounting bracket is removable attached to said elongated member.
