20130272786 | STRESS REDUCING TOOL MOUNT - According to aspects of one or more exemplary implementations, disclosed is a plastic tool mount and system with a tool connector head with a back side, nose and distal end of said nose; a shaft guide having a channel is formed within said head open at the distal end of said nose; said channel further having a raised bump section of plastic extending from a wall of said shaft guide into the shaft guide channel; and, wherein the diameter of the shaft guide channel at the location of the raised bump is diminished. | 10-17-2013 |
20130276597 | DISPOSABLE TORQUE LIMITING DEVICE WITH BELT COUNTER - A torque limiting driver with a belt driven use indicator, having a body with a shaft and tool at one end and a counter or indicator at the other end, is disclosed. The indicator is driven by a drive shaft and belt corresponding to movement of the tool. The indicator provides at least one visual cue which corresponds to a predetermined amount of use, or end of life. Alignment of the at least one visual cue with a sight or mark may be used to estimate or determine usage. | 10-24-2013 |

20140070498 | END ALIGNED FLEXIBLE CONNECTION SLEEVES - A latch and catch arrangement is disclosed, whereby a sleeve supporting a flexible hinge is oriented over a bearing in guide. An asymmetrical alignment via a latch and catch between the sleeve and tool collar orients a flexible hinge, which may be of reduced thickness, over a bearing in a guide. The bearing moves upward when a tool is inserted into a tool socket, and the flexible hinge, properly oriented by the alignment catch/latch, keeps the bearing in the tool socket while allowing necessary movement to insert and remove a tool. | 03-13-2014 |
