Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An apparatus for removing a window frame from a wall opening comprising:
 a lever arm pivotally connected to a fulcrum,   the fulcrum extending downward from the lever arm to a sturdy base;   a locking clamp pivotally connected to a load end of the lever; and   a handle at the distal, effort end of the lever.   
     
     
         2 . The apparatus described in  claim 1 , the fulcrum further comprising:
 a bracket pivotally supporting the lever arm by a horizontal pin joining the bracket to a point along the length of the lever arm;   the bracket swivelly attached to the sturdy base.   
     
     
         3 . The apparatus described in  claim 2 , wherein the bracket further comprises:
 a spreader extending between the top of two sides;   the two sides extending down around the lever arm; and mating to   a bottom, such that the bracket encircles the lever arm.   
     
     
         4 . The apparatus described in  claim 2 , wherein the sturdy base further comprises:
 a removably attached expanded base secured to the sturdy base's lower face.   
     
     
         5 . The apparatus described in  claim 4 , wherein the expanded base is based to one corner of the sturdy base. 
     
     
         6 . The apparatus described in  claim 4 , wherein the expanded base:
 is slip resistant and/or textured.   
     
     
         7 . The apparatus described in  claim 4 , wherein the expanded base:
 is compressible and/or non-marking.   
     
     
         8 . The apparatus described in  claim 1 , wherein the locking clamp:
 aligns with the central axis of the lever arm passing directly over the fulcrum.   
     
     
         9 . A method of removing a window frame from a wall opening comprising:
 using a frame puller comprising:
 a lever arm pivotally connected to a fulcrum; 
 the fulcrum extending downward from the lever arm to a sturdy base; 
 a locking clamp pivotally connected to a load end of the fulcrum; and 
 a handle at the distal, effort end of the lever; 
   attaching the locking clamp to the center of a side of the window frame;   positioning the sturdy base against an adjacent sill;   prying the window frame to pull it away from the wall opening;   releasing the locking clamp; and   repositioning to repeat as necessary until the frame is free of the opening.   
     
     
         10 . The method described in  claim 9  further comprising:
 bending the side of the window frame at the clamp attachment locating; and 
 bending the window frame at the corners, 
 such that the frame folds for removal. 
 
     
     
         11 . The method described in  claim 9  wherein the fulcrum further comprises:
 the fulcrum being swivelly attached to the sturdy base; 
 such that the method further comprises:
 swiveling the locking clamp to a corner of the sturdy base; 
 attaching the locking clamp near a corner of the flame; 
 positioning a at least a portion of the sturdy base against an adjacent sill; 
 prying the window frame to pull it away from the opening.
