Abstract: The present invention comprises a machining apparatus including a work piece holder having an adapter body with an axial bore and a translating portion located within the axial bore of the adapter body. The translating portion has a proximal end for coupling with a retention knob collet of a spindle and a distal end for attaching to a collet. The work piece holder includes a retaining piece coupling the adapter body and the translating portion allowing the translating portion to move axially within the adapter body. The apparatus facilitates a rotating spindle grasping and rotating a work piece to be brought into contact with a processing tool held stationary on a work table. The present invention also includes a fixture block for attaching milling tools and other devices to a work table and a method of operating a milling machine utilizing the fixture block and work piece holder.

Abstract: A turning apparatus for a CNC or other turning machine comprises a faceplate having a locating insert secured and located therein for locating a part on a taper thereof. The turning apparatus clamps and draws the part into the locating insert to facilitate machining of the part. The insert is readily replaceable to accommodate a part having a different taper.

Abstract: The quick change insert system of the present invention utilizes a removable locking pin and an insert sleeve to permit easy replacement of an insert pin within a sleeve. Insert pin replacement occurs by removing the locking pin. After removing the locking pin, the insert sleeve is removed together with the insert pin. The insert pin is separated from the insert sleeve, and a replacement insert pin is put in its place. The new insert pin and the insert sleeve slide back into the sleeve, and the locking pin secures the insert pin and the insert sleeve to the sleeve. The present invention does not require the removing or re-adjusting of the sleeve during insert pin replacement. Furthermore, the present invention permits easy replacement of other sleeve assembly parts during part to part changeover and eliminates costly inventory of sleeve assemblies.

Abstract: An integrally formed display tray having forward and rear compartments for placement on existing shelving in a retail store. The forward compartment is connected to the rear compartment in depending fashion to overhang the shelf. Dividers may be placed in aligned pairs of vertical slots to segregate the products in the tray.

Abstract: A drilling and thread forming screw including a shank portion with a head at one end and a drill point at the other end. The shank includes a threaded portion having a minor diameter and a major diameter. The drill point defines a segment of a cone having a base and a point. The base intersects the shank at the minor diameter of the shank. This screw is adapted to drill into a substrate up to the minor diameter of the shank and then to form female threads in the substrate.
