Abstract: 1,035,198. Machine tool details. D. T. N. WILLIAMSON, C. E. T. SMITH, J. H. SWARBRICK, and MOLINS MACHINE CO. Ltd. Nov. 20, 1963 [Nov. 21, 1962], No. 44063/62. Headings B3B and B3K. A gripping device for gripping a rod-like article T in a rotatable spindle 3 comprises a sleeve 39 contained within a collet 36 having tapered ends so that forward movement of the collet causes the article to be gripped by a radial force, and means 32 to restrain forward movement of the sleeve relatively to the spindle. A ring 31, which is split into four segments causes locking of a nose tube 34 when the collet is moved axially by springs 51 acting through a collar 49 and a sleeve 35. The collar can be retracted by a piston 54 attached to a pulling member 56. The split sleeve 39 is held against the shoulder 32 on the tube 34 by a spring 41. The tool T has a dog 43 to engage a groove in a head 44 on a rod 45 held forwardly by a spring 48. The whole structure and its operation are very similar to those described in Specification 1,035,197 except that, additionally, a brake disc 88 can be advanced to engage a nut 26 on the spindle 3 by means of air-operated plungers 91. In operation, when pressure is admitted to the front side of the piston 54, the cylinder 55 moves forwardly and the brake 88 abuts against the nut 26. The piston 54 then moves rearwardly and the draw-bar 52 is operated to allow the chuck to open. When a new tool has been inserted, spindle 3 is rotated slowly to allow the dog 43 to register and the drawbar is then released. After a machining operation, the spindle is stopped by applying the brake 88.

Engine 10 has a carburreter 20 which supplies a 12:1 air-fuel mixture to cylinders 11, 12 and 13, and a second carburetter 21 which supplies an 18:1 mixture to cylinders 14, 15 and 16. Valve and ignition timings are set so that cylinders 11 and 16 fire simultaneously, then cylinders 13 and 14 and finally cylinders 12 and 15. Cylinders 11, 12 and 13 exhaust into manifold 30 and the remaining cylinders into manifold 31. Manifold 30 opens tangentially into circular section reactor 53 and manifold 31 is positioned on the axis of the reactor and terminates in a swirl vane 59 to promote mixing of the gases. Unburned fuel and carbon monoxide in the exhaust gas from the first manifold is oxidized by the excess oxygen in the exhaust gas from the second manifold. In a modification, the tube 57 is closed-ended and the terminal wall portion is perforated. Air injection nozzles 61, 62 and 63 may be provided to supply secondary air under low load conditions. The pairing of the cylinders may be changed so that cylinders 11 and 12, 13 and 14, 15 and 16 fire simultaneously. Consequential modification of the manifolding is necessary. Fig. 4 (not shown) shows a four-cylinder engine in which cylinders 11b and 12b fire simultaneously and then cylinders 13b and 14b. The exhaust manifold 34 has a central partition 36 in its outlet 35 which leads into an inner cylindrical reaction chamber 73. Gases entering the chamber pass through perforated partitions 78, then through perforations 76 in the end portions of the cylinder into a space 74 between the inner chamber and surrounding outer chamber 72. Secondary air injection nozzles are provided. Pairing of the cylinders may be altered as in the sixcylinder engine.
