| J. S. Murray - patent attorney
This invention relates to tool holders for screw machine use and particularly holders for cutoff and form tools. As heretofore constructed, holders for cutoff and form tools have been suited to only one size of tool or else to a few slightly differing sizes. Also provisions heretofore made for resisting back thrust of such tools have lacked any convenient forward and back adjustment. Prior tool holders, moreover, have not been designed to afford removal of the tool, when necessary, without first removing the holder from its supporting slide. An object of the present invention is to provide a tool holder suited to operatively receive a considerable range of differently sized tools. Another object is to equip a tool holder with an abutment receiving the back thrust or cutting reaction of the tool, and designed to function for any location of the tool in the holder and for any size tool insertable in the holder, and adjustable forwardly and back to afford compensation for tool wear and to regulate the extent of exposed length of the tool. Another object is to adopt a cutting tool to be clamped in a novel and very secure manner in its holder, facilitating a lateral removal of the tool from the holder.
