  • Patent number: 4161310
    Abstract: An elongated bar is pivotally affixed at one end thereof to one end of a shaft-like support member for rotation in the plane of the bar and the support member in directions toward and away from the support member. A base plate affixed to the opposite end of the support member supports it in upright position adjacent a metal fence post. A rod-like cross member is affixed to the bar at the pivoted end thereof and extends perpendicularly thereto. A coupling device couples the bar to the fence post so that when the coupling device is positioned astraddle the fence post and in contact with a projection of the fence post and with the cross member of the bar, manual force applied downward in the area of the second end of the bar exerts a much greater force upward on the fence post.
