ABSTRACT:
A bearing located internally and concentrically with respect to a hollow cylinder, such as a truck axle or a paper making machine cylinder, may at times be difficult to remove by conventional tools, especially if the bearing possesses a broken part or contains a flaw. The present tool provides a U shaped bridge having feet adapted to rest on the end of the cylinder, which becomes a foundation for operation of the device; centrally of the bridge there is a turnscrew member like a bolt, the lower end of which including a blocking nut, while the bolt is surrounded by a sliding plaque provided with an elongated U shaped opening, the smaller side of the opening being barely sufficient to surround the bolt the plaque is rectangular of smaller side lesser than the inside of the bearing and larger side smaller than the outside of the bearing. A second bolt located one, the transverse part of the bridge is directed towards the closed end of the plaque so that when a force is applied on the central bolt and the second bolt is resting on the closed end of the plaque the open U end of the plaque may be brought to bear against a desirable area of the bearing.
