Abstract: Above and below water and land pile cutting machine is provided having a main frame which is quadrangular in transverse cross-section and is shaped to receive in the center thereof the pile to be cut. The upper portion of the main frame carries extensible pile gripping clamp means; the center portion carries four circular saws each mounted on a carriage mounted for transverse reciprocation and the lower portion of the frame carries further pile gripping extensible clamping means.

Abstract: A cutting machine for concrete piles and the like having an annular elongate frame positionable around a concrete pile, with first and second sets of guide members in spaced-apart relation to align the frame with the pile, first and second sets of movable clamps for locking the frame to the concrete pile, annular track means on the frame and a cutter head with drive means movably mounted on the annular track means and having a cutter-carrying arm movable across the top of the frame to engage the wall of the concrete pile.

Abstract: Apparatus for movably mounting and guiding rotary cutting equipment comprise an elongate track support having a circular cross-section, at least two distinct, mutually spaced elongate tracks extending along the track support and projecting from the track support beyond the periphery of the circular cross-section, a carriage for mounting rotary cutting equipment movable on the tracks along the elongate track support and equipment on the carriage and on the track support beyond the periphery of the circular cross-section for propelling, and for selectively arresting, the carriage relative to the tracks.

Abstract: An apparatus that is mountable upon a work table, and which is used to support various portable power tools during operative use, so as to work efficiently and accurately; the apparatus including a vertical table frame stationarily mounted upon the table, the table frame including rails, along which there can be rolled a back plate of a carrier assembly, the carrier assembly being adaptable for various power tools to be attached thereto.

Abstract: A stone and concrete cutting machine is described for performing cutting operations on stone or concrete surfaces. The machine includes an elongated base that is mountable to a stone or concrete surface through a bracket mechanism that is releasably received on the base. The base is comprised of one or more lengths of triangular cross-sectional tubing that provides rigid support for a truck mechanism movably mounted thereon. A number of rollers are rotatably mounted to a truck mechanism and engage three separate walls of the base to allow longitudinal movement of the truck mechanism along the length of the base. A hollow standard protrudes from the base to movably mount a cutting head carriage. A cutting head is mounted to the carriage through an adapter assembly that facilitates selective positioning of the cutting head on either of two sides of the standard.

Abstract: A device for rigidly supporting a portable power saw and permitting selective vertical movement thereof for cutting lengths of metal, plastic, wood and the like. A base having a horizontal work surface includes a clamping means for clamping the work to be cut in a predetermined position. An upstanding support post slidably carries a saw support arm to which a portable power saw is secured with the cutting element thereof disposed in a vertical plane. Lever means connected with the saw support arm permits the selective vertical movement of the saw through the clamped worked piece. Spring means are provided to return and retain the saw and saw support arm to a raised position above the work piece.
