The object of my invention is to provide an attachment for lathes or other machine tools by the use of which various operations incident to such tools may be performed in an expeditious and effective manner and with the exercise of a small amount of labor; and a further object is to provide a light portable tool of this class that can be readily attached to any lathe or machine tool in common use thereby increasing its efficiency.
I claim as my invention:
1. In a tool holder for a lathe or like machine tool, a support adapted to be secured in a tool post of a lathe, the body part of the holder pivotally supported upon the support, the graduations borne on the body part and on the support respectively, the tool holder held against rotation within the body part but free to move lengthwise therein, the feed screw held against lengthwise movement within the body part, and a hand wheel borne on the body part and adapted to engage the feed screw whereby a lengthwise movement of the tool holder is obtained, all substantially as described.
2. In combination in an attachment for a lathe or like machine tool, a support secured to the lathe, the body part pivoted on the support, a pulley borne in the body part so as to rotate therein, a spindle having means of attachment thereto and extending lengthwise through the body part and through the pulley and having lengthwise movement therein but secured to the pulley to rotate therewith, and a button rotatably mounted on the end of the spindle, all substantially as described.
3. In combination in an attachment for a lathe or like machine tool, a body part having means of attachment to a lathe, a tool holder located in the body part, a feed screw engaging the tool holder, a spindle extending through the holder and through the feed screw and adapted to be secured to each and also having free lengthwise movement there in, a hand wheel mounted on the feed screw and adapted to be secured to the feed screw, and a pulley borne in the hand wheel and free to revolve independently thereof and secured to the spindle to compel its rotation but allowing it a lengthwise movement therein, all substantially as described.
4. In combination in an attachment for a lathe or like machine tool, a support, a body part pivoted to the support, a tool holder borne in the body part, a feed screw borne in the holder and in the body part, a hand wheel borne on the feed screw, a pulley borne in the hand wheel, a shoe supported in an annular groove in the hub of the pulley, an adjusting screw passing through the hub of the hand wheel and engaging the shoe, and a spindle extending through the pulley to rotate therewith but having lengthwise movement therein, all substantially as described.
5. In combination with a lathe or like machine tool, a support attached thereto, a body part pivoted to the support, graduations on the support and body part, the tool holder borne in the body part and having a lengthwise groove, a screw from the body part engaging said groove, a set screw in the tool holder, a feed screw engaging the holder and held against lengthwise movement in the body part, a hand wheel supported on the feed screw and adapted to be secured thereto, a pulley borne in the hand wheel, pins engaging the pulley and groove in the spindle and a spindle with the lengthwise groove and adapted to be secured to the hand wheel and to the tool holder, all substantially as described. |
