Abstract: Disclosed herein is a universal pipe lathe for performing plural cutting operations on pipe and the like including a lathe structure having a clamp for affixing the pipe to the lathe, a drive motor supported on a stationary ring member, and a rotatable second ring driven by the motor upon which second ring is provided cutting tools of various configurations and oriented in specific fashions so as to provide a plurality of cutting combinations for the apparatus. Additionally, an indexing mechanism is provided for advancing the cutting tool and the clamping mechanism for retaining the lathe on the pipe can be adapted to engage the pipe internally or externally. The pipe lathe has two major sections which allow the lathe to be straddled over a pipe, and a suspension mechanism is provided so that the lathe can depend from a sling suspension, or alternatively be supported by an underlying support carriage.

Abstract: A quick release pipe vise having a base plate with a set of lower jaws secured thereto. An upper jaw frame is pivotally secured to the base plate and carries a screw adjustable upper jaw which can be brought into clamping relation with the lower jaw when the upper jaw frame is locked in its upper position. An over dead center linkage extends from the upper part of the frame to the base plate and when in over center locked position rigidly secures the upper jaw frame in its upright operative position. A handle on the over center linkage permits the linkage to be moved out of its locked over center position to pivot the upper jaw frame away from its upright position to thus move the upper jaw away from the lower jaw to release pipe clamped therebetween.
