Shake nail puller

A nail puller pliers provided with a fulcrum lever that is adjustable to the contour of the surface on which it rests. One embodiment has a resilient pad mounted to the free end of the fulcrum lever. Another embodiment has the pad mounted to the free end of the fulcrum lever by use of a ball and socket joint. A further embodiment has a resilient foot threadably mounted to the pad disposed on the free end of the fulcrum lever. A final embodiment has the fulcrum lever pivotally mounted to the second end of the second arm.

BACKGROUND OF THE INVENTION 
The present invention relates to a nail puller plier. More particularly, it 
relates to a nail puller plier that has a fulcrum lever. 
Nail puller pliers of the above mentioned general type are known in the 
art. fore example, U.S. Pat. No. 1,891,164 to Kluglein teaches a tack 
extractor in the shape of pliers with pulling jaws and a laterally 
extending brace used as a fulcrum. Another example, U.S. Pat. No. 145,830 
to Baker et al teaches a tool that combines a nail extractor, a hammer, 
pliers and nail claw and contains a lever which acts as a fulcrum. A final 
example, U.S. Pat. No. 2,070,2176 Seger teaches a tool having a projecting 
portion which serves as a fulcrum about which the device may be rocked. 
The nail puller pliers of the prior art contain the disadvantage that their 
fulcrum levers are not adjustable to the contour of the surface on which 
they rest. 
SUMMARY OF THE INVENTION 
Accordingly, it is an object of the present invention to provide a nail 
puller pliers which avoids the disadvantages of the prior art. 
Another object of the present invention is to provide a nail puller pliers 
having a fulcrum lever which is adjustable to the contour of the surface 
on which it rests. 
Yet another object of the present invention is to provide a nail puller 
pliers which has a resilient pad mounted on the free end of the fulcrum 
lever which can displace up and down and rotate in a ball and socket 
joint. 
Still another object of the present invention is to provide a nail puller 
pliers in which the fulcrum lever is pivotly mounted to the second end of 
the second arm. 
Further objects of the invention will appear as the description proceeds. 
To the accomplishment of the above and related objects, this invention may 
be embodied in the form illustrated in the accompanying drawings, 
attention being called to the fact, however that the drawings are 
illustrative only, and that changes may be made in the specific 
construction illustrated and described within the scope of the appended 
claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
Referring now to FIG. 1, the nail puller is shown generally at 10 having a 
first arm 12 and a second arm 14. The first arm 12 is found at one end 
with a first jaw 16. The second arm 14 is formed at one end with a second 
jaw 18 and a fulcrum lever 20. The first arm 12 and the second arm 14 are 
pivotaly mounted to each other at a pivot point 22. 
The other ends of the first arm 12 and the second arm 14 are formed as 
handles 24 and 26, respectively, for gripping by the user. Free ends 28 
and 30 of the first jaw 16 and the second jaw 18, respectively, are formed 
with recesses 32 and 34, respectively, which grip the nail head of the 
nail to be pulled. The fulcrum lever 20 has a free end onto which is 
attached a removably mounted pad 36. The pad 36 may be made out of a 
resilient material so as to conform to the contour of the area to which 
the fulcrum lever 20 is applied. 
In operation the first and second jaws 16 and 18, respectively, are opened 
and closed around the nail so that the nail head is seated in the recesses 
32 and 34. The pad 36 of the fulcrum lever 20 is rested on a supporting 
area. The user grips the handles 24 and 26 and exerts a force in the 
direction of arrow 38, pulling up the nail. While the force is applied in 
the direction of the arrow 38, a force ia applied on the fulcrum lever 20, 
in the direction of arrow 40, and thus assisting in the removal of the 
nail. 
In FIG. 2, an alternate embodiment of the nail puller is shown generally at 
10'. Parts that are identical to the embodiment shown in FIG. 1 will be 
designated by similar numbers. The fulcrum lever 20' is pivotally mounted 
at a first end 42 to the second arm 14 on a pivot pin 44. Surrounding the 
pivot pin 44 are snap locks 46 which lock the fulcrum lever 20' in a 
number of positions as it pivots laterally. At a free end 46 of the 
fulcrum lever 20', a pad 36' is mounted by means of a ball and socket 
joint 48. On a lower end 50 of the pad 36', a foot 52, is threadably 
mounted and is displaceable in an up and down direction.
