Abstract
A portable lathe usable on site for preparing the end of a pipe preparatory to an operation, such as welding another pipe thereto, comprising a frame, a tool head carried by said frame and rotatable about an axis and having a tool post which movably mounts a tool slide for movement radially of said axis, and means for moving said tool slide including a feed cam on the frame, a clutch driven lead screw on the tool post, and a rigid link for transmitting motion imparted by said cam to said clutch.
Claims5
A portable lathe comprising, a frame, a tool head rotatably mounted on said frame, means for rotating said toolhead, a tool post, means pivotally mounting said tool post on said tool head, a tool slide movable along the tool post, means for positioning the tool post at various angles relative to said tool head, and means for advancing said tool slide along the tool post in response to rotation of said tool head relative to the frame including a cam on said frame, a cam follower, means movably mounting said cam follower on said tool head, a tool slide feed means on the tool post, and a motion-transmitting connection between said cam follower and said tool slide feed means including a rigid link having two interconnected elongate members with one member connected at an end to the cam follower and the other member connected at an end to the tool slide feed means and with the members between said ends having their lengths associated together in overlapped sliding relation to vary the length of the link dependent on the overlap between the elongate members to accommodate said various tool post angles, and means for fixedly interconnecting said elongate members whereby the motion of the cam follower is transmitted through the link to the tool slide feed means to feed the tool slide.
