A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning. In Commonwealth English (excluding Canada), spanner is the standard term. The most common shapes are called open-ended spanner and ring spanner. The term wrench is generally used for tools that turn non-fastening devices (e.g. tap wrench and pipe wrench), or may be used for a monkey wrench - an adjustable pipe wrench.

Minimally invasive pedicle screw and guide support

A minimally invasive orthopedic bone attachment system comprising a pedicle screw and guide support sleeve for insertion of the screw. The pedicle screw is a self-boring, self-tapping integral screw having a distal sharply pointed end for guiding the insertion of the screw as well as forming a borehole for the self-tapping threads of the screw. The proximal end of the screw provides a cylindrical extension which can include a recess for receiving a rotational drive tool or wrench. The length of the threads and the type of threads provided in the screw are designed for the type of orthopedic surgery that is intended. A relatively thin hollow support sleeve including an internal threaded section in the distal end is provided to match the threads and the length of the threaded portion of the pedicle screw. The proximal end of the sleeve includes a central passageway having an internal diameter that can receive the extension portion of the screw and also guide and receive a drive device for the screw. A retainer clip associated with circumferential slots spacedly indexed along the longitudinal surface of the drive device can be used to limit the depth of the screw upon insertion as well as to lock the drive device as an assembly with the screw and sleeve to form the attachment system. A small diameter passageway can be provided along the longitudinal axis of the assembly extending from the proximal end of the drive device through the screw to exit through the pointed distal end of the screw. A thin rigid rod having a point at the distal end is slidably positioned within the narrow passageway. The proximal end of the road includes a cap. A flange surface on the under portion of the cap limits the travel of the rod through the assembly. The length of the rod is determined so that it equals the length of the assembly plus an additional dimension corresponding to the anticipated installed depth of the screw. Prior to insertion of the screw, the rod is driven into the bone through the assembly. The location of the rod is ascertained by an image guidance system to determine the correct final projected location of the screw upon installation.

Golf putter with adjustable weight system

An improved golf putter incorporating a weight management system that allows for adjustment of a golf club head weighting by incorporating an adjustable weight system wherein weights may be removed and replaced quickly and easily without requiring a specialized tool is disclosed. Weights received within weight ports formed in the heel and toe portions of the putter are maintained securely affixed within the club head body by plugs adapted for snap fit engagement with the club head. Unlike other putter weight adjustment systems disclosed in the art, the present invention does not require use of a special tool, such as a wrench, to remove and replace the weights. While the preferred golf club embodiment disclosed is a putter, the present invention contemplates incorporating any of the features and/or advancements disclosed herein into any golf club. In addition, the present invention further includes novel aspects relating to overall design, including mass distribution and a rearwardly projecting portion having an upwardly sloped sole that prevents the club from snagging the turf. Furthermore a hollowed out area formed within the rearwardly projecting portion is sized and shaped to receive a correspondingly sized and shaped sensing module adapted to measure club head movement and wirelessly transmit data to a remote graphical user interface.

Motor vehicle pneumatic jacklift system

A permanently mounted pneumatic jack (jacklift) system for motor vehicles, as well as an impact wrench for removing and installing lug nuts. The system provides a quick and safe means of lifting one or more tires off the ground for replacement of a spare or rotating the tires on a motor vehicle. The present invention comprises two or more (typically four) pneumatic jacks, a system ON/OFF switch, an air compressor, a 120-psi air tank, air lines (hoses), individual jack extend/retract switches, jack position-locking pins, safety-locking pins, and impact wrench. Each jack can be locked in a horizontal stowaway or vertical operational position. The jack is cylindrical shaped with a telescopic body that can be extended or retracted as needed to raise and lower the vehicle. A solid cylindrical lift rod slides inside a cylindrical outer housing with a high-pressure seal means used to maintain pressure on the support rod. A ground support foot (plate) is mounted on the lower end of the solid cylindrical lift rod to provide sufficient traction with the ground to support the lifting process. A quick release air coupler is included on the pneumatic chamber to support the use of an air hose and impact wrench. An extend/retract toggle switch is included on each jack to control a solenoid valve to allow the air to flow into the jack. A quick release safety-locking pin is used to mechanically pin the solid cylindrical lift rod to the outer housing once the desired height is achieved to assure that the vehicle does not fall down in the event of a high-pressure air loss, thereby providing safety to the person(s) working around the vehicle. An air compressor located in the engine compartment of the vehicle is mechanically belt-driven off the engine. A high-pressure air line carries the air to a high-pressure (at least 120-psi) air tank located in the trunk or other suitable storage area on the vehicle. Separate air lines extend from the air tank to the individual jacks.

Tool handle for holding multiple tools of different sizes during use

A generally cylindrical shaped tool handle holds multiple sizes of tools. The handle includes one or more holding slots each positioned on one of multiple outer surface faces into which tools are inserted and held. Each holding slot includes one or more contoured compartments in which tools rest when engaged with the handle. Each contoured compartment is of a size and dimension which corresponds to one or more tool sizes. In the preferred embodiment of the tool handle, three of its outer surface faces have a continuous holding slot with multiple receiving holes for inserting therein hexagonal wrenches of multiple sizes. The continuous holding slots of the preferred embodiment of the handle include multiple contoured compartments for holding an inserted hexagonal wrench. Each contoured compartment is formed about a corresponding receiving hole. A lock is positioned over the contoured compartment to irremovably confine the short leg of the hexagonal wrench within the contoured compartment. Hexagonal shaped tools other than wrenches may be used with the handle of the present invention such as screwdrivers and socket wrenches. A tool holder of the present invention is designed to slide over the handle and to hold multiple sizes of tools which may be used with the handle. The tool holder includes a tool holding member having a plurality of cavities for inserting therein appropriately sized tools and a tool handle holding member having a cavity with an inner hollow shape corresponding to a shape of the handle.
