Device and method for repairing mortar joints between chimmey tiles |
摘要 |
A device for repairing a chimney preferably includes a rod effective for positioning and manipulating a camera and a plunger blade in a chimney; a camera attached to the lower portion of the rod in a manner such that rotation of the rod results in a corresponding rotation of the camera; and a plunger blade attached to the rod above the camera. The plunger blade is adapted to apply mortar to the sides of a chimney when the device is pulled upward in the chimney. The device may further include a camera-direction indicator attached to the rod above the plunger blade in a manner such that the camera-direction indicator is effective for indicating the direction of view of said camera even when the camera is not visible to the operator. |
