A puller comprising a hub having at least three load blocks disposed and retained thereabout by upper and lower end caps is presented. The load blocks are retained about the hub by the end caps so as to allow individual positioning of the load blocks at any circumferential position about the hub. A pressure bolt or screw extends through the center of the hub for providing the pulling force. The grippers or jaws are attached at the respective load blocks. In a preferred embodiment, the grippers comprises an external gripping member and an internal gripping member interconnected by a pair of load linking members. The gripper members each including respective article engaging surfaces or hooks.

Versatile pulling tool

A method and apparatus are provided for controlling the movement of a surface traversing apparatus across a member which has an ordered array of openings in it's surface. Move control routines are provided, each of which instruct the traversing apparatus to move incrementally over the surface of the member by disengaging, incrementally moving, and re-engaging one of two stepping arms. Each routine operates to advance the apparatus an increment in one of a number of directions. Some of the routines move the apparatus parallel to lines or rows of openings. Others move the apparatus diagonally. Each routine senses the relative positioning of the two stepping arms to establish the sequence of operations and returns the stepping arm to its former position if it is unable to complete a step. An automatic selection operation may move the apparatus toward a target opening by comparing the present location of the apparatus with the target address and selecting a routine which minimizes the number of move increments needed to get to the target.

Method and apparatus for controlling surface traversing device

An improved surface traversing apparatus has an anchor finger selectively movable laterally of another anchor finger into near or substantial alignment with an opening in a member for insertion thereinto and includes one or more of the fingers being mounted to a base portion of the platform by a mounting arrangement which allows one finger to be deflected laterally relative to another finger such that the finger being inserted may deflect into exact alignment with the receiving opening by lateral engagement with the sidewall of the opening. Each finger is resiliently mounted to a connecting member which is, in turn, connected to the base portion of the platform. The resilient mount for each finger normally centers the finger and allows both pivotal and translatory displacement of the finger relative to the connecting member. A cylindrical adaptor is fixed to the finger and is radially supported in a circular opening in the connecting member by a resilient O-ring therebetween in mutually opposing radial engagement therewith.
