Abstract: 319,995. Lurf, K., and Collet & Engelhard Werkzeugmaschinenfabrik Akt.-Ges. Dec. 5, 1928. Lathe drivers and carriers.-In a driver and carrier for wheel lathes employing a number of eccentrically mounted dogs having serrated faces for gripping the work, the dogs are operated through the intermediary of springs so as to allow the work to be gripped yieldingly and centrally in spite of any irregularities in its surface. In one form each dog 1, Figs. 1 and 2, is carried by a spindle 17 rotatable in a bracket 2 which is pivoted to the face-plate 3 by means of a bolt 4 and is set angularly with the aid of a locking screw 5 and a scale 6. An operating lever 7 carries a toothed segment 8 engaging a rack 9 to which is attached a shank 10 provided with a head 14. Between the head and a second rack 11 is a spring 12 the rack 11 engaging a toothed segment 16 on the dog spindle 17. In operation, rotation of the lever 7 in the direction of the arrows rotates the dog yielding through the spring 12, and a second spring 13, between the head 14 and a fixed collar 15, assists in restoring the dog to its normal position when the pressure is released. Two dogs at diametrically opposite parts of the face-plate are preferably provided, and both levers 7 may be operated simultaneously by a ring 18 on the face-plate which may be restrained while the latter is rotated and carries pins 19 engaging the sides of the levers or slots therein. Holes are provided in the periphery of the ring for the insertion of handles and ratchet teeth may also be provided for engagement with a pawl operated by a hand crank. Alternatively, the ring 18 may be operated by a brake &c. In a modified construction the toothed segment 8<1>, Fig. 5, on the lever 7<1> engages a rack which also meshes directly with the toothed segment 16<1>. The latter is connected to the dog 1<1> by a spring 20<1> and to the face plate 3<1> by a spring 21<1>. In operation, rotation of the lever 7<1> rotates the sector 16<1> and this imparts to the dog 1<1> a yielding rotation and also an axial movement which carries a sleeve 26<1>, loosely surrounding the sector, to oscillate a bell-crank lever 23<1> and allows a spring 28<1> to press a paw] 25<1> into contact with the teeth of the sector 8<1> and lock the mechanism in the gripping position. To release the grip, end pressure is exerted on the work to move it away from the face-plate, whereupon the sleeve 26<1> is moved axially to oscillate the lever 23<1> and remove the pawl 25<1>, thus allowing the spring 21' to restore the parts to the inoperative position.

Title: Improvements in and relating to devices for producing intermittent signals
Inventor: SOLOMIDES LOUIS ZENON
IPC: B61L5/18
Filed: 1958-03-12
Abstract: 815,781. Visible signalling apparatus. LONDEX Ltd. March 12, 1958, No. 35975/54. Class 118 (2). A signalling device of the type wherein a lamp supplied by a battery is intermittently flashed has a variable resistor connected in series with the lamp which is automatically controlled by the flashing mechanism so as to reduce the resistance in circuit as the voltage of the battery decreases. Thus a battery of higher voltage than normally required for the lamp may be used. until its voltage has dropped to a value requiring no resistance in circuit, thereby lengthening the useful period before changing or re-charging the battery is necessary. A battery 2 supplies current via contacts 7, 9 and a main switch 8 to a lamp 1 and electromagnet 6. The electromagnet 6 attracts an armature 5 on the flywheel 3 which rotates to open contacts 7, 9 whereupon the electromagnet 6 is de-energized and the lamp 1 is extinguished. A spiral spring 4 returns the flywheel 3 to press contact 7 against contact 9 which is mounted on a leaf-spring 10. The latter is thereby depressed an amount depending on the amplitude of oscillation of the flywheel 3, which is determined by the voltage of the battery 2. A resistor 12 is carried on the end of spring 10 to co-operate with a contact 11 supported on the insulating base 13 such that the depression of spring 10 inserts resistance into the circuit of lamp 1 in accordance with the battery voltage.
