Abstract: A tool holder. Implementations include a base unit which receives a shank of a cutting tool. A dowel movably coupled to the base unit engages an indentation in the shank under spring bias force to removably couple the cutting tool with the base unit. A sleeve slidably couples over the base unit, the sliding of which causes the dowel to ride in a first slot in the base unit and simultaneously in a second slot in the sleeve, causing the dowel to engage the indentation when the sleeve is slid in one direction and disengage the indentation when the sleeve is slid the opposite direction.

Abstract: An end mill has a plurality of quick change insert holders for cutter inserts on machine tools. Each of the plurality of quick change tool holders comprises a housing having at least one seat portion which is adapted to receive a cutter insert. A clamping arm is movably mounted in the insert housing and has a clamp portion adapted to engage a cutter insert extending over the seat portion. A locking mechanism is contained within the housing. The locking mechanism has a clamp position which forces the clamp portion of the clamping arm to engage a cutter insert and a release position which forces the clamp portion to disengage from a cutter insert. The locking mechanism moves between the release position and the clamp position.

Abstract: A self contained, toolless quick change tool holder for trigon cutter inserts on machine tools comprises a housing having at least one seat portion which is adapted to receive and conform to the shape of a variant shaped cutter insert. A fork is mounted in the insert housing and is movable within the insert housing. The fork engages a variant shaped cutter insert. A locking mechanism is contained within the housing and has a clamp position which forces the clamp portion to engage a variant shaped cutter insert and a release position which forces the clamp portion to disengage from a variant shaped cutter insert to allow removal and replacement of said variant shaped shaped cutter insert. The locking mechanism moves between the release position and the clamp position.

Abstract: A quick change tool holder is provided for cutter inserts on machine tools which comprises a housing which is adapted to receive and conform to the shape of a cutter insert. A pivoting arm is mounted in the insert housing and rotates about a pivot therein. The pivoting arm has a clamp portion extending from the pivot to a position over a seat portion which is adapted to engage a cutter insert. In addition, the pivoting arm has an arm extending from the pivot opposite the clamp portion. Lastly, a cam is engaged by a distal end of the arm. The cam has a clamp position which forces the clamp portion to engage a cutter insert and a release position which forces the clamp portion to disengage from a cutter insert to allow thereof. The cam moves between the release position and the clamp position.

Abstract: A vertical machining center is retrofitted to permit the automatic machining of a plurality of like unfixtured parts loaded into the vertical machining center on a tray.

Abstract: A storage container for model railroad cars includes a pair of spaced apart foam cushions on the top and bottom of the container. The cushions compress and secure the railroad cars in fixed position in the storage container. The cushions are cut from a single piece of foam material.

Abstract: A weapon system which utilizes pressurized gas to propel a projectile from a barrel and which utilizes a shearable diaphragm member to permit the pressure of gas in the weapon to increase to a selected point before the gas propels the projectile from the barrel.

Abstract: Apparatus for installing a cleat on the sole of a golf shoe. The cleat includes a pair of apertures which each open outwardly away from the sole of the golf shoe and includes an externally threaded screw on the back of the cleat which turns into an internally threaded aperture formed in the sole of the golf shoe. The apparatus includes a pair of feet each shaped to engage the cleat by fitting in one of the cleat apertures. The apparatus is rotated to turn the cleat and rotate the externally threaded cleat screw into the internally threaded sole aperture. While the apparatus is being rotated, it can be tilted with respect to the sole of the golf shoe without causing either of the cleat--engaging feet to lift free from its associated aperture in the cleat.

Abstract: Hand held water powered apparatus for removing scale from the tile circumscribing a swimming pool at the waterline of the pool.

Abstract: An improved thread measuring tool. The tool translates linear motion into rotational motion to provide the motive power for turning a thread gauge into a threaded bore in a workpiece.
