Title: Improvements in accessories for automatic lathes for turning thread reels
IPC: B23B7/12
Filed: 1924-11-26
Abstract: 250,139. Cronstr÷m, H. Nov. 26, 1924. Combined turning and drilling machines.-An automatic machine for drilling and turning thread reels, particularly a machine as described in Specification 248,068, is provided with a device for positioning the drilled blanks between the lathe centres and for ensuring that the end-facing operation does not begin until the blank is correctly centred. The rough cylinder conveyed to the lathe by the arms of the feed mechanism described in Specification 251,203 is held between the turning-spindle 147 and back-centre 148, by a stop 151 on a spring-pressed rod 150 arranged in the shaft 157, rotation of the rod 150 being prevented by a forked arm 152 mounted on the rod 150 and engaging a guide rod 154. The back centre shaft is provided with a head 164 having openings at the top to permit the insertion of a turning-tool for facing one end of the reel. In order to prevent this tool from coming into action too soon, the blank is normally held clear of the head by a pin 165 controlled by a bell crank lever 166 one end of which normally rests on a collar on a roa 171 which is drawn by a spring 167 into a recess 169 on the head. During the forward movement of the back-centre shaft the rod 171 is stopped by the engagement of adjustable nuts 172 with the frame, whereupon further forward movement causes the bell crank to step from its collar, thus withdrawing the pin to permit the end facing operation to commence. The back-centre shaft is adjustable in the fixed stock 149 by a hand-wheel 176 and is moved axially by adjustable lever mechanism actuated from a cam 197 on the shaft 106. In order to provide a safety device in the event of the back-centre shaft encountering undue resistance, the fulcrum 182 of the feed level is connected to a bell-crank lever 186 having a fixed pivot 185 and supporting at the lower end weights which are raised to allow movement of the fulcrum 182 when an obstruction is encountered. When the turning of a reel is completed and the back-centre is moving away, the finished work-piece is pushed off the spindle by an ejector 240 which during the turning is retracted by a spring 237 into a groove in the radius head 202 and is actuated at the required moment by a cam 246 on the shaft 106 acting through lever mechanism. The finished reels pass through an aperture in the frame into a receptacle.

Patent GB-829843-A (GB)
Title: Machine tool
IPC: B21K1/70
Filed: 1957-10-15
Abstract: 829,843. Forging nuts. GRIP NUT CO. Oct. 15, 1957 [Dec. 13, 1956], No. 32154/57. Class 83 (4). A machine-tool, particularly for indenting nuts, comprises a plurality of simultaneouslyacting radially-movable tools 34, 36, 38, means 20, Fig. 2, for feeding workpieces 56 into a working position and a device 298 sensitive to the force exerted by the tools on the workpiece for causing simultaneous disengagement of the tools when this force exceeds a predetermined value. A tool for indenting the sides of hexagon nuts 56 to produce locknuts of the kind described in Specification 826,062 has its indenting tools 34, 36, 38, Fig. 1, actuated by double-acting hydraulic motors 28, 30, 32. Each tool comprises an indenting ball 216, Fig. 11 (not shown), mounted in an adjustable holder 206. The nuts are gravity fed down a shoot 20, Fig. 2, to a receiving station 22 from which they are raised to a work station 24 by a pusher 26 actuated by a double-acting hydraulic motor 66. At the work station the nuts are located in an adjustable indexing fixture 102, Figs. 8, 9 (not shown). Hydraulic fluid is supplied from a reservoir 226 by a motor-driven pump 230 which delivers it through a pressure-relief valve 236 to solenoidactuated reversing valve 242. At the start of a working cycle the fluid passes through a manually-adjusted throttle valve 254 and pipe 256 to a lower part 98 of motor 66 whereupon the pusher 26 raises the nut to the work station 24. At the end of the upstroke a spring 284 on a rod 276 attached to the motor piston actuates a switch 266 controlling the solenoid 264 of a shutoff valve 262 which is thereby opened to pass hydraulic fluid along pipes 290, 292, 294 to the tool-actuating motors 34, 36, 38. The nut is thus indented by the ball tools. At the end of this operation resistance to the movement of the tools increases, resulting in an increase in fluid pressure which acts through pipe 296 on a pressure-responsive device 298, Fig. 12 (not shown). This actuates a switch 250 controlling the solenoid of valve 242 which is then reversed to cause the tools to be retracted and the pusher 26 lowered. During the downward movement of motor 26 an air valve 320 is opened by a collar 278 whereby air passes to an air-ejector 44 to remove the nut into a discharge shoot 46, Fig. 1. At the end of the downstroke collar 278 actuates switch 266 which again closes valve 262. U.S.A. Specifications 2,686,546 and 2,754,871 also are referred to.
