Abstract: An object gripping device for removing and installing bulbs and other objects. The device has around its circumference three or more vertical gripping posts. The device uses a sun gear and planetary gears to transmit the user's twisting motion to a gripping force applied equally around the object's circumference. Furthermore, the gearing ratio can be adjusted to create more or less leverage or gripping force applied to the bulb or object. The device could also be applied to gripping any object that is semi-cylindrical in shape. For instance, a robot can use the invented gear system to pick up or grip objects in a factory, laboratory, hospital, space exploration or home setting. Instead of a handle used to rotate the sun gear a drive shaft can be attached. An electric motor, a gas or diesel engine, a hydraulic power pack can rotate the drive shaft.

Abstract: A lightweight, adjustable wrench comprising of a moveable jaw with a reach that is shortened or lengthened with a strap or a cable. The loose end of the strap or cable is secured to the wrench's shank by a cam lock, or similar locking device. Since the strap or cable is the means for the wrench's jaws adjustment, a quicker and easier fit to the pipe or object to be gripped can be obtained. The wrench is more convenient to adjust, since the means for adjustment are located near the handle of the wrench as opposed to the shank end of present designs. The strap or cable adjustment also allows the wrench's shank and handle to be designed hollow and a larger diameter to reduce weight. The wrench can be made in any proportion for any sized application.
