Abstract: According to an aspect of the present disclosure, a low profile travelling pipe cutter is provided which is adapted to perform at least one of cutting and beveling a hollow vessel while traveling around the vessel using a cutting tool mounted thereon. The pipe cutter includes inner and outer carriages, a capstan assembly attached to the outer carriage to which a feed cable is attached, and rollers attached to the outer carriage to which a tension cable is attached. The force adjustment assembly changes the vertical position of the outer carriage relative to the inner carriage to compensate for the pipe cutter going inwardly and outwardly as it travels around a hollow vessel in order to maintain constant pressure caused by the lever tension interface. A guard assembly is provided for covering and uncovering the cutting tool during cutting.

Abstract: A pipe end machining device configured to machine an end of a pipe includes an outer housing, a spindle rotatably mounted within the outer housing and configured to carry tool supports and cutting tools, a mounting assembly configured to be attached to the pipe, a stem extending from the mounting assembly and connected to the spindle by an interengagement which allows the spindle to move linearly relative to the stem, but prevents rotational movement of the spindle relative to the stem, and a locking assembly attached to the stem and configured to fix the vertical position of the outer housing and the spindle relative to the mounting assembly.

Abstract: A pipe end machining device configured to machine an end of a pipe includes an outer housing having a spindle rotatably mounted therein, tool carriers are mounted on the spindle, a hub assembly attached to the outer housing, a vertical adjustment assembly attached to the hub assembly and to the outer housing, and a drive assembly configured to rotate the spindle and tool carriers. The vertical adjustment assembly adjusts the upward and downward position of the cutting tools relative to the pipe. The hub assembly mounts the device to the pipe and fixes the relative upward or downward position of the cutting tools relative to the pipe, thereby preventing vibration and chatter when the device is cutting a planar surface on the end of the pipe.

Abstract: A cutting tool to cut a hollow vessel includes a conical member, a plurality of grooves, and a plurality of cutting members. The plurality of grooves are disposed in a semi-helix around an outer conical surface of the conical member. Each of the plurality of cutting members is disposed in fixed position within one of the plurality of grooves at a non-zero angle relative to a vertical axis.

Abstract: A pipe machining apparatus includes a frame, a tool support mounted on a tool carrier which is mounted on the frame, and a gearing arrangement for rotating the frame, and a motor for rotating the gearing arrangement. The gearing arrangement includes a toothed pinion gear, a toothed backlash adjustment gear which is moveable relative to the pinion gear and being capable of being fixed in position relative to the pinion gear by a locking assembly, and a toothed bull gear affixed to the tool carrier. The teeth of the bull gear are capable of being engaged with the teeth of the pinion gear and with the teeth of the backlash adjustment gear, the bull gear to minimize backlash.

Abstract: An apparatus for cutting pipes internally includes at least one cutting member, at least one drive member, at least one feed member, and at least one clamping member. The at least one cutting member cuts a pipe internally. The at least one drive member rotates the at least one cutting member to cut the pipe internally. The at least one feed member extend the at least one cutting member against the pipe internally and retracts the at least one cutting member from the pipe internally. The at least one clamping member secures the apparatus to the pipe internally.

Abstract: A kit is disclosed for cutting differing sized pipes internally. The kit includes a pipe cutting apparatus, and a plurality of assemblies. The pipe cutting apparatus includes at least one drive member. The plurality of assemblies, attachable to the pipe cutting apparatus, each include: (1) at least one feed member to extend at least one cutting member against a pipe internally and to retract the at least one cutting member from the pipe internally, the at least one drive member to rotate the at least one cutting member against the pipe internally; or (2) at least one clamping member to secure the pipe cutting apparatus to the pipe internally. Each of the plurality of assemblies differ in size so that differing sized pipes can be cut internally by the pipe cutting apparatus by attaching the appropriately sized assembly to the pipe cutting apparatus.
