The prongs of the tool are 50 then pushed underthe tack head until the extremity of sliding movement is reached, i. e. notch engages the tack. The tool is then rocked slightly to the right in causes the tack to be slightly elevated from its hole in the shoe sole. The bent end of the tack has become straightened by this preliminary movement Where fulcrum M is positioned to give maximum leverage and the tack may now be completely removed or Withdrawn, by the use of the fulcrum 3, without enlarging or tearing the hole in the shoe sole as is shown in Figure 12. It will be noted that the displacement of fulcrum 3 from the tack is considerable, consequently the tack is removed in substantially a straight lift.

The foregoing description and the accompanying drawing are believed to clearly disclose a preferred embodiment of my invention; and it is believed that it will be apparent that the device of my invention is simple to use, and will be economical to manufacture, and will fill a long felt need in the art of shoe repairing, or in other fields where the device may be employed to advantage. c 7

Having thus fully described my invention, what I claim as new and desire to secure by LettersPatent is: f I

1'. A tool for removing clinched tacks comprising a handle andshanlz, said shank having a fulcrum on the under side thereof, a claw on said shank and including a cup-shaped head having a notch therein forming a pair of tack engaging prongs and the bottom of said head being substantially thicker than the points of the prongs at a point rearward of the vertical axis of the head to form a fulcrum whereby the force applied through the latter fulcrum will straighten the clinched tack and force applied through the former fulcrum will Withdraw the straightened tack.

2. A tool for removing clinched tacks comprising a handle and shank, said shank having a fulcrum on the under side thereof, a claw on said shank disposed angularly thereof and including a cup-shaped head having a notch therein forming a pair of tack engaging prongs and the bottom of said head being substantially thicker than the points of the prongs at a point rearward of thevertical axis of the head to form a fulcrum whereby the force applied throughthe latterfulcrum will straighten the clinched tack and force applied through the formerfulcrum will withdraw the straightened tack.
