Title: Improvements in or relating to automatic screw or like machines for fashioning articles successively from bar stock
IPC: B23B13/00
Filed: 1936-01-02
Abstract: 468,625. Control of motors. BROWN & SHARPE MFG. CO. Jan. 2, 1936, No. 150. Convention date, Jan. 5, 1935. [Class 38 (iii)] [Also in Group XXII] Travelling to predetermined limits.-Automatic feed mechanism for feeding stock-bars to a machine for fashioning articles successively from bar-stock is in part similar to that described in Specification 423,837 with respect to the ratchet mechanism for moving the rack-bar 92, Fig. 1, which throws out the feed a predetermined time after the rear end of the stock passes the lever 84. In the present device the rack-bar 92 carries an abutment 112 which closes a switch 114 thus completing a circuit through the coil 238, Fig. 10, to close the switch contactors 234 supplying current to a motor 68, the main switch 232 being previously closed. The motor 68, Fig. 1, drives, through worm gearing and a pinion 78, a rack-bar 50 which carries at one end the feed member 48 for engaging the rear end of a new stock-bar. An escapement, similar to that used in Specification 423,837, is used to allow a new stock-bar to be dropped into the feed channel 24 and the rocking lever 36, Fig. 2, of this mechanism is controlled by a roller 60 carried by the crosshead 58 which is fixed to the rack-bar 50. After operating the escapement, further movement of the feed member 50 serves to feed the new stock-bar and also to release a lever 127 which allows a spring-operated switch 200, in the circuit of a solenoid 162, to close. A flap 174, Fig. 9, positioned in the path of the stockbar is operated by the leading end thereof to close the toggle switch 178 and thus close the circuit to the solenoid 162. This operates by withdrawing a pin 152, Fig. 6 (section on bent line 66 of Fig. 2) to release a clutch member 148 which connects the moving cross-head 58 with a slidable control rod 123. The latter carries at its forward end a forked bracket 126 which engages stops carried on a switch rod 130. The stop 134 is so positioned that the switch rod is moved when it is necessary to operate, through a further stop 136, the reversing switch 140, Figs. 1 and 10, which opens the control circuit of the switch 234 and effects the closing of the switch 236 through the coil 240, the motor 68 is thereby reversed. The feed rack 50 now commences its return movement during which the switches and the clutch member 148 are reset for a new forward feed movement and the motor is brought to rest by a stop 136 on the rod 130 operating through the switch 140 to open the switch 234. Alternative controls including switches 214 and 220, Fig. 10, are provided where it is desired to stop the motor during forward feed and restart it after the completion of the last article on the old bar, when the time required to select and advance a new bar is less than that required for the completion of the last article. Specification 300,619, [Class 83 (iii)], also is referred to.

Abstract: 523,553. Winding yarn. BARZAGHI, A. Jan. 4, 1939, Nos. 304 and 305. Convention dates, Jan. 4, 1938, and July 2, 1938. [Class 120 (ii)] In a machine for winding crosswound bobbins the yarn is traversed by an element forming a continuous circular yarn guiding rim transversely mounted at an inclination on a shaft running parallel to the axis of the bobbin and passing through the centre of the element, the guiding rim being intersected at two diametrically opposite points to form deviating members by which the yarn is alternately guided over the right side of one half of the disc and over the left side of the other half to reverse the traverse, the deviating members are usually arranged at diametrically-opposite points in the rim, but they may be arranged to give portions of the rim of different lengths when it is desired to wind a bobbin of asymmetrical profile. As shown, the element or disc 3 is mounted on the shaft 5 arranged parallel to the axis of the bobbin 1 and the roller 2 driving it and the yarn 7 passes from the supply 8 through a tension device 10 and over the convex edge of a segment 11 which compensates for variation in tension as the yarn is traversed. The diameter of the disc determines the length of bobbin produced, and the guiding edge may be rounded and bent or curved to lesson the frictional resistance to the yarn; the deviating members or notches 4, 4<SP>1</SP> may vary in depth and may be rounded. The disc may be formed with cut-away parts into which the deviating members or incisions lead and the cut-away parts may be such that the disc consists of an annular rim interrupted at two places by the deviating incisions the rim being connected to the shaft by spokes adjacent the incisions.

The transducer means have body members 96, 98 with three pairs of aligned apertures 102, 104. Mask 109 with slots 110 limits the light beams. When vanes 122 move in grooves 120, slots 124 allow light to reach sensors 108. On removal of retaining pins 134, which limit motion, vanes 122 are removeable. Each means 90 has a body portion 125 with a flange 129 and a plastics or rubber gripping member 132 held in a recess in head 128. When a force acts on means 90, portion 125 slides in aperture 126 depressing vane 122. Biasing means 130 may be an elastomeric material or a metal or plastics spring and its stress/ displacement characteristic may be linear. It may Fig. 5 (not shown) have a triangular cross-section, so that the rate of deformation decreases with increased force. Transducer means 78, Fig. 7 is similar to 88, but the biasing means 130A is between wall 76 of plate 144, restrained in recess 150 by its flanges 146 against stop members 148 on wall 76. Soft rubber biasing means 157 is under head 128A. So long as external force is applied to cover plate 154 within the projected area of means 130A, the displacement of vane 122A is proportional to it. The sources maybe L.E.D.s and the sensors phototransistors.  A slip sensor 92, Fig. 3, comprises supporting members 160 attached to jaw wall 86 having elongated apertures 168 in which resilient biasing means 170 urge shaft 166 and its attached disc 164 outwardly. When an object is gripped between jaws 29, 30 disc 164 is urged inwardly. When slippage occurs a plurality of radial slits 174 in disc 164 pass between sources 176, 178 and sensors 180, 182, which are placed so that their outputs are 90 degrees out of phase. The number of pulses generated indicates the amount of slippage and the phase the direction. As in Figs. 1 and 10, the manipulator includes housing 16 for supporting jaws 29, 30 and a motor 25 for moving them and having brackets 194 with notches 196 receiving crosshead 200 of a T-shaped, handle of a tool 198, which has flats 202 gripped by the jaws.
