Abstract: A machine tool is provided having a wide range of applications and uses in metal or other material fabrication. Such machine tool may be utilized on reactor flanges, pipes, and other equipment. The machine tool is pneumatically actuated and may include a vertical spindle on which may be attached a grinder, brush, or other apparatus for polishing, grinding, or contouring a workpiece. A pneumatically driven mechanism for the machine tool includes a plurality of worm gears positioned and arranged for selective rotational speed and tongue of the spindle of such tool. Essentially, the machine tool or universal tool combines functions achieved with a plurality of known tools in a single unitary tool assembly having reliability, simplicity, economy, and durability.

Abstract: A portable milling machine is provided for solving in-place machining problems encountered on turbines, pumps, electric motor bases, and other types of field equipment requiring a close tolerance, machined surface prior to installation. Such portable milling machine is set up at a job-site using a plurality of levels in conjunction with an optical leveling kit and a vertical scale magnetically mounted at selective locations on such portable milling machine during set-up. The set-up time for such portable milling machine substantially is cut in half by using levels in conjunction with optics and accuracy may be achieved within 0.001 to 0.002 of an inch.

Abstract: A flange grooving tool for grooving or re-grooving flanges in relatively small tubular members, having novel means for adjusting a cutting member to the desired circumferential path and having means for the direct gear drive of a rotating member at a controlled speed.

Abstract: A multi-purpose facing tool mounted on an adjustable boom for cutting faces on flanges, and the like, or cutting grooves in flange faces, adaptable to many sizes of flanges, having novel driving means mounted on the retaining spider, and including an adjustable guide means for maintaining the boom and boom supporting means aligned and in constantly driving position.

Abstract: A tool for facing the ends of tubular material having means for supporting the tool on the work and having novel means for suspending a rotating member on the supporting means, said rotating member having a cutting tool movable on the work, the cutting tool being removably mounted in the rotating member and having novel means for feeding the cutting tool to the work as the rotating member rotates.

Abstract: A pipe beveling machine for forming a beveled end to receive a weld, having a driving mechanism and a driven mechanism, the driving mechanism being movable into driving relation with the driven mechanism and the driven mechanism having means for anchoring a portion thereof into the work, moving slips against the inside wall thereof and being keyed to the driving mechanism, and a cutting head which extends laterally from the driven mechanism and is provided with a feed mechanism for moving the cutter into the work, said cutter being mounted in a pivotal cutter holder and being advanced into the work with each revolution of the driven mechanism.

Abstract: A unit for milling rectangular work members, where a machined fit is required, such as the door facings of a filter unit having a series of doors into an exchange unit, or equipment bases where a pump or turbine is being installed which requires a machined surface and it is necessary to accomplish the cut in place.
