Abstract: A work piece positioning device which has a table upon which the work piece is supported is disclosed. The table is rotatably mounted on a sub-assembly which is tiltably mounted on a frame such that the work piece can be positioned in any desired predetermined attitude. Two worm gear systems are utilized for positioning the table, one for the rotating action and one for the tilting action. Each worm gear system has a worm gear, a tiltable worm and a locking mechanism. Once the table and work piece are in the desired predetermined attitude, the locking mechanisms are actuated, locking each worm to its respective worm gear.

Abstract: A machining system for simultaneously performing a number of machining operations on one face of a plurality of work pieces which are carried on a pallet is disclosed. The machining system includes a track having a pallet loading station and a pallet unloading station juxtaposed to the track, and at least one machining station juxtaposed to the track at a location between the loading and unloading stations. A plurality of pallets are supported for movement along the track between the unloading and loading stations and passed the machining station. Each pallet is set up for mounting at least one work piece in a predetermined position thereon. The system also includes a series of mechanisms for moving the pallet along the track, a mechanism for locating and securing each pallet in a predetermined location at the machining station.

Abstract: A sheet of glass or similar material is moved to and in the cutting area of the apparatus by sheet gripping assemblies that engage and grip an edge portion of the sheet, and that undergo precise controlled movement. A fluid-jet discharging nozzle moves above the sheet along a path of travel normal to the sheet movement. Belts supportively underlying the sheet are driven sufficiently in unison therewith to minimize possible scratching or other marring of the glass. To the same end, the lower portion of the fluid-jet nozzle is of tapered shape. Sheet-engaging clamps of the gripping assemblies are moveable in a manner adapted to prevent damage to the glass sheets engaged thereby. Positioning structure may be provided for receiving and positioning the glass sheets preparatory to the cutting thereof.
