Abstract
Abstract A bushing removing tool which includes an elongated handle portion and an operative head extending transversely of the handle portion and to one side thereof. A hook projection at an end of the operative head faces away from the handle portion and is engageable with the interior of a tubular bushing while a portion of the operative head remote from the hook projection acts as a fulcrum so that the tool can be swung to cause the hook projection to free the bushing from a bushing support.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
116 words
A device for removing a tubular bushing from a tubular bushing support which comprises a handle portion, and an operative head extending transversely of the handle portion and to one side thereof, the operative head being bar-like with a slot therein to form a hook projection adjacent an end of the operative head and facing away from the handle portion, the hook projection being engageable with the interior of the bushing while a portion of the operative head remote and on an opposed side of the operative head from the hook projection acts as a fulcrum so that the tool can be swung to cause the hook projection to free the bushing from the bushing support.
Claim 2
Independent Claim
116 words
A device for removing a tubular bushing from a tubular bushing support which comprises a handle portion, and an operative head extending transversely of the handle portion and to one side thereof, the operative head being bar-like with a slot therein to form a hook projection adjacent an end of the operative head and facing away from the handle portion, the hook projection being engageable with the interior of the bushing while a portion of the operative head remote and on an opposed side of the operative head from the hook projection acts as a fulcrum so that the tool can be swung to cause the hook projection to free the bushing from the bushing support.
Claim 3
Dependent Claim
59 words
A device as in claim 1 wherein the handle portion is elongated, an intermediate portion connects the handle portion to the operative head, the operative head, the intermediate portion and the handle portion are integral and bar-like, and the axis of the operative head extends at an angle of approximately 80 degrees to the axis of the handle portion.
Claim 4
Dependent Claim
101 words
A device as in claim 1 wherein the operative head as a surface area facing away from the handle portion and adjacent said hook portion but spaced therefrom by said slot, a portion of said surface area tending to cooperatively engage the bushing when the operative head is near parallel relation to the bushing surface engaged by said hook under an operating force applied to said handle and the portion of said surface area engaging said bushing decreasing as said operating head nears perpendicular relation to the bushing surface engaged by said hook under said operating force applied to said handle.
