IPC: B23B23/00
Filed: 1950-10-26
Abstract: 674,609. Lathe and like centres. FISCHER AKT.-GES., G. Oct. 26, 1950 [Nov. 30, 1949], No. 26122/50. Class 83 (iii). Tailstocks.-A tailstock for lathes and like machines comprises a work-engaging device enclosed by a sleeve to which is secured a threaded rod, a gear wheel engaging said rod, a bearing enclosing a part of the gear wheel, resilient means axially supporting the bearing, a motor, means connecting the motor to the gear wheel for moving the work-engaging device longitudinally and switching mechanism to stop the motor when the work is engaged, or when the work-engaging device has moved a predetermined distance away from the work. A work-engaging centre 17, Fig. 3, may be eccentrically mounted and is carried in antifriction bearings in a sleeve 13 keyed at 15 for slidable movement within a bore 12 in the tailstock casing 2. The casing is slidable along ways 1, Fig. 1, of the machine and may be clamped by nuts 3a. A threaded rod 18, integral with the sleeve 13, engages a nut 19 provided with a toothed periphery and urged to the left by a spring 22, thrust member 38, and bearing 20. Movement by the spring to the left is arrested when the bearing engages a collar 36 provided on a sleeve 21 integral with the casing 2. The nut 19 is rotated in one direction or the other for forward motion or retraction of the tailstock centre by a reversible electric motor 5 driving through gears 6, 7 and 10. The gear wheel 10 has a flanged extension bearing against a spring 11 and is splined on a shaft 8. A hand lever 33, Fig. 1, operates a switch 32 for the motor to give " forward," " reverse," or " off and has an extension 30 comprising a fork which engages a pin 29, Fig. 3, on a cranked lever 26 pivoted to the casing at 24 and with a lower end 27 engaging the rear end 37 of the sleeve 13. A further pin 28 on the lever engages the flange on the gear wheel 10. When the lever 33 is moved to the forward " on " position, motor 5 rotates the gearing and nut 19 to screw out the centre sleeve 13 until the centre proper contacts the work, spring 22 is then compressed by further movement, the nut 19 being forced back and carrying with it the wheel 10 through contact with the flange on this wheel. The latter moves to the right against a compression spring 8 and its flange bears against the pin 28, thus moving the lever 26 until the switch lever is moved into the " off " position to stop the motor. When the lever 33 is moved to the opposite "on" position and the direction of motor rotation is reversed, the sleeve 13 moves back to contact alternately a pin 27 on the lower arm of the lever 26 and thus again moves the switch to the " off " position to stop the motor. A foot-operated safety switch may be employed in the supply lines to the motor.

Filed: 1939-09-21
Abstract: 532,976. Power and supply meters. SANGAMO WESTON. Ltd. Sept. 21, 1939, No. 26364. Convention date, April 17, 1939. [Class 37] A meter stresses a spring through a differential gear to an extent depending on the power so as to indicate power and maximum demand and also the integrated energy. The disc 60, Fig. 2, of an induction type energy meter drives a worm-wheel 64 on a shaft 65 which carries a notched wheel 100. This causes contacts 104 to engage and disengage and thereby make and break the circuit of an electromagnet 107 which steps round a ratchet wheel 113 mounted on a shaft 114, in correspondence with the motion of the shaft 65. The shaft 114 drives the counting train 71 and also one sun-wheel 76 of a differential gear, the other sun-wheel 78 of which drives a damping disc 84. The planetwheels 88 of the differential gear are carried by a shaft 89, rotation of which is controlled by a spring 91. The shaft 89 carries a pusher arm 93 which engages a maximum demand pointer 94 and may also carry an indicating pointer. In a modification the shaft 65 is geared to the shaft 114, the contact breaker 104, magnet 107, and ratchet-wheel 113 being dispensed with. The Specification as open to inspection under Sect. 91 comprises also the following subject-matter, which does not appear in the Specification as accepted. In the demand meter shown in Fig. 2 (Cancelled) a conducting disc 14 is mounted on a shaft 11 so as to rotate in the air gap between voltage aud current magnets 16, 20. Rotation of the disc 14 due to eddy currents induced therein is opposed by a spiral spring 25 and its motion is damped by a copper or aluminium disc 34 driven from the shaft 11 by gearing 29, 30 and rotatable between the poles of permanent magnets 35. Driven from the shaft 11 by bevel gearing 40, 41 is a shaft 42 carrying a pusher around 47 which passes through an arcuate aperture in a dial plate 46 and is provided with a pointer 49 indicating power. The pusher arm 47 engages a pin 51 carried by a maximum demand pointer 52 which is thus moved forward but held at its maximum position by a bowed friction spring 55.
