  • Patent number: 11072057
    Abstract: A bearing removal tool includes a plurality of hook arms and a connecting disk. Each hook arm has a connecting space for engaging with a peripheral portion of the connecting disk, and there are specific dimensional relationships between the connecting spaces and the connecting disk such that, once the connecting disk is fitted into the connecting spaces of the hook arms, the user only has to move the hook arms laterally for a predetermined distance in order for the hook arms to be restricted by the connecting disk and prevented from separating from the connecting disk. The bearing removal tool, therefore, can be put together more easily and more rapidly than its prior art counterparts.

A grasping clevis is movable in response to the leverage structure. A control having an actuation portion is connected to the brace and positioned so that the grasping clevis abuts the actuation portion of the control at least when the grasping clevis is grasping the closure member of the bottle, the actuation portion being associated with the position of the closure element which causes the grasping clevis to close when the grasping clevis is moved to a grasping position.

  • Patent number: 4514890
    Abstract: The tool assembly enables installation in and removal from a combustion engine block of freeze plugs. The puller component has a plug penetrating point which is forced through the plug to define an opening. Spreader segments associated with the point can be spread laterally into engagement with the edge of the opening. Means are provided for imposing a retraction force on the segments, which cooperate to pull the plug free. A fresh plug is inserted in the freeze plug opening by utilization of an installer head shaped to releasably hold the plug during insertion in the opening after which the head can be withdrawn. Special leverage and force application arrangements are associated with the puller and installer head.

  • Patent number: 4429447
    Abstract: A bearing cup installing tool adjustable for installation of bearings of various diameters. The tool has a cross head with a driving handle connected thereto and extending from one side thereof. An adjusting screw associated with the cross head extends outwardly therefrom from a side opposite the driving handle and three jaws are pivotally mounted on the cross head in equally-spaced relation and extending from the same side of the cross head as the adjusting screw and disposed in a circular array with the adjusting screw at the center. Each jaw has a bearing cup engaging notch at a free end thereof. The adjusting screw can be moved lengthwise of the cross head, by coacting structure on the adjusting screw and the jaws, to pivot the jaws to set an effective diameter as defined by the bearing cup engaging notches for engagement with a bearing cup.

  • Patent number: 4045856
    Abstract: A pulling tool is used for pulling an object relative to a support. The pulling tool includes a pole having means at one end for engaging an object to be pulled. A stop is affixed at a selected position on the pole. A threaded, rotatable sleeve loosely or slidably receives the pole and has one end for abutment with the stop and another end from which the engaging means projects. An annular member threadedly engages the exterior of the sleeve to allow movement of the sleeve axially of the annular member upon rotation of the sleeve. A stand-off means is coupled to the annular member for engaging the support while the object is being pulled, and there is a handle for turning the sleeve to retract the sleeve and the pole relative to the fixed support.
