Abstract

783,144. Automatic-lathe details. SENECA FALLS MACHINE CO. Oct. 7, 1955 [Aug. 19, 1955], No. 28668/55. Class 83 (3). An automatic-lathe has work-gauging mechanism in combination with a rotatable toolholder in which a number of cutting-tools are mounted in a circular series with one tool only in the cutting-position, incremental advancemovements being given to this tool on indication of work oversize and, after a predetermined number of incremental advances, means operative to retract and index the tool-holder to bring a new cutting-tool into operative position. A number of tools T are carried in a turret-head 10 rotatably-supported by a housing 12 forming part of a transverse-slide 14. The latter is movable in a longitudinally-adjustable carriage 16, fed for turning work W by means, not described. A known gauging-device G bears against the work behind the tool-cut and, on a predetermined over-size of the work, operates a solenoid S, which moves a rack 41 and rotates a pawl-carrying wheel 32. The latter thus rotates a ratchet-wheel 30 through a tooth increment, in turn rotating a cam 25 which bears against a roller 24 secured to a slide-bar 20 intersecting the slide 14. A cam 22 secured to the slide-bar 20 bears against a fixed roller 23 so that, as the slide-bar is moved by the cam, the tool-head is fed towards the work to correct the oversize. When a tool has worn so that it has been advanced the full range of the cam 25, a stop-pin 50 on the cam closes a switch 51 operating a solenoid 52, which, through further rack-and-pinion and ratchet-gear, rotates the tool-turret one step. The tool is thus changed automatically and the slide-bar 20 is returned to its initial position ready for a fresh cycle of incremental feeds with the new tool. This process is repeated for all the tools, after which a switch 88 is opened to stop the machine. An eccentric pin 85 is moved by a lever 84 and solenoid 82 to clamp the turret-head 12 in its housing 14. A locking-ring 70 on the lower end of the turret-head has four notches and is engaged by a locking-pawl 72 when a tool is brought into the required position.
