Title: Method and apparatus for pulling extrusions from an extrusion press
IPC: B21C35/02
Filed: 1966-01-13
Abstract: 1,129,221. Extruding. XPRESS AUTOMATION Inc. 13 Jan., 1966 [21 Jan., 1965], No. 1614/66. Heading B3P. An extruded product 42 is pulled from an extrusion press 20 by a gripping device 38 sliding along a run-out table 32 and comprising a plurality of individually movable gripping elements (97), Fig. 5 (not shown). A billet 30 placed in a container 27, is extruded by a ram 25 through one or more die openings 31 in a die 22. The extruded product or products are gripped by serrated edges (102), Fig. 4 (not shown), on the pivoted gripping elements (97), when the latter have been released from an inoperative upper latched position by engagement with a cam 41. The gripping device 38 runs along a rail 40 at the side of the run-out table 32 consisting of graphite blocks (37), Fig. 1 (not shown). Movement of the device 38 is effected by a cable 51 passing over pulleys 50, 52, 53, 56 and tensioned by a piston/ cylinder mechanism 54, 55. Pulley 50 is driven by a reversible electric motor (45), Fig. 13 (not shown) through an eddy current slipping clutch (46) ; an electrically operated brake is also provided. When the billet 30 has been almost wholly extruded, the container 27 is retracted and a shear 29 is actuated by a cylinder 28 to sever the discord. The clutch (46) is then energized with high power thereby causing the gripper mechanism 38 to pull the extruded products (E), Fig. 3 (not shown), which may be of angle section, out of the die. When the gripper 38 engages a cam 43, the gripping elements are released from the extruded products and a vacuum cylinder mechanism 62 then actuates a resiliently mounted jaw (66), Fig. 12 (not shown) to clamp the extruded products against a stationary block 67. Transverse conveyer elements (77), Figs. 8, 9 (not shown) are then raised by cams (75) operated by cylinder (76) to lift the extruded products from the table ; these conveyer elements are then moved transversely by rack and pinion mechanism (82), (81) driven by mechanism (80), Fig. 1 (not shown), to remove the extruded products on to a bed (83). Motor (45) is then reversed to return the gripper mechanism 38 to a rest position adjacent the press where it is stopped by the brake. Cooling means C such as a water spray are provided above the run-out table. An electric control system is described, Fig. 13 (not shown). Alternatively an hydraulic or pneumatic control system may be used.

Title: Improvements in or relating to an arbor chuck
IPC: B23B31/02
Filed: 1954-01-20
Abstract: 746,404. Chucks and mandrels. WOODWORTH CO., N. A. Jan. 20, 1954 [Feb. 9, 1953], No. 1699/54. Class 83 (3). An expanding-mandrel or chuck-collet comprises a tubular body with rigid circumferentially-continuous ends 30, slots 26 intermediate the ends dividing the body into radially-flexible members 28 and one or more bosses 34 on each member 28, together defining work-engaging means. The mandrel shown in Fig. 1 is for gripping short bore in the work and, as the diameter of the bosses 34 is slightly greater than that of the bore, the mandrel must be forced into the bore, thus causing the members 28 to flex into a concave shape and the bosses 34 to engage the bore only at their outer edges so that the work is accurately centred at right angles to the mandrel axis. For ease in handling, knurled ridges 44 are provided and, for mounting between centres for checking the work, plugs 22 are fitted in the ends of the body. Two work-engaging surfaces of different radii may be provided on the bosses, with a relieved portion between them, and a flange forming an end stop on one of them. In an alternative form, the body has a mounting shank at one end and a centre plug at the other end; in this form, the bosses have threads for gripping a screwed bore and the body may be constricted, so that work can be screwed on the threads, by means such as a cable anchored at one end, wrapped round the body and connected to a tensioning lever. The collet of Fig. 7 has spaced gripping-surfaces or, as shown, splines 132 fitting into splines on the work 136 and the flexible members 28 have internal conesurfaces 102 so that they can be positively expanded by a rod 104 bearing against an adjusting screw 110. A driver 138 is provided and also an end stop, which may be a plain sleeve fitting closely on a part 96 of the body, or a sleeve 146 mounted on a flexible ring 150 and having ends 152, 154 tapered at right angles to each other so that the sleeve can rock to accommodate itself to a work-face which is not at right angles to the axis of the bore being chucked. In Fig. 8, the big-end of the collet body is secured to a cylinder 162, and fluid supplied through a pipe 176 moves the piston 168 to expand the collet, the piston being returned by springs 170. In Fig. 11, the collet is adapted for external gripping of twodiameter work 210 and is contracted by a screwed bevel-closing ring 220. Alternate surfaces 202, 204 on each boss are relieved at 206, 208 in staggered relation round the circumference of the collet so that each boss grips its corresponding diameter independently, and therefore the collet adapts itself to varying tolerances on the two diameters. End stops 226 are provided on each flexible member.

Title: Improvements relating to slack adjusters for fluid pressure braking apparatus
IPC: B61H15/00
Filed: 1923-01-19
Abstract: 204,998. Tomlinson, A. V., (Westing house Air Brake Co.). Jan. 19, 1923. Compensating for wear. - A slack-adjusting device comprises a separate fluid-pressure cylinder carried by and adapted to adjust the length of the tie rod which extends between the usual brake levers connected to the main brake cylinder. The tie rod 4, Fig. 4, which is pivoted to levers 23, 24 operatively connected to the main brake cylinder 25, comprises in one form end members 28 telescoping into members 30 bolted to the subsidiary cylinder 29 within which work the pistons 33, 33' connected by a rib 34 having a guiding projection 17. A pawl 37 is pivoted on the rib 34 and engages a ratchet 31 on a rod 32 the ends of which are screwed into the parts 28 of the tie rod. If there is excessive slack in the brake rigging, the piston of the main cylinder 25 moves sufficiently to uncover a port whereby compressed air is supplied by the pipe 38 to the space above the piston 33 which is thereby moved to compress springs 35, 36. When in the release of the brakes, the cylinder is exhausted, the springs 35, 36 return the piston 33 and turn the ratchet 31 by the pawl 37 thus shortening the effective length of the tie rod. For resetting the adjusting means the hub of the ratchet 31 may have a bevel wheel 39 gearing with a bevel wheel 39<a> on a shaft 40 having a squared end 41 to which a handle may be fitted. The pawl 37 may be disengaged for the resetting operation by a bell-crank lever 42 pivoted on the rib 34 and actuated by a notched pin 43 provided with a handle 44. The engagement of the lever 42 with the notched pin also serves to prevent the springs 35, 36 from completely moving the piston 33 out of the cylinder when taking down the cylinder. Relief wedges 21 are provided for engagement with the ends of the screwed rod 32 when the maximum amount of adjustment has been effected ; these wedges may be tapped on the under side to permit the pawl 37 and piston 33 to complete their stroke. Other forms are shown in which adjustment of one end of the tie rod is effected; in which the ratchet-wheel 31 is formed on a nut which turns on a screwed rod fixed to the part 28 and in which the tension in the tie rod is not transmitted to the cylinder 29.

Abstract: 509,850. Disposition of guns on aircraft. AMIOT, F. Jan. 24, 1938, No. 2299. Convention date, Jan. 25, 1937. [Class 4] [Also in Group XXI] Gun cockpits on aircraft are arranged in pairs within the hull, body, or the like and are arranged to be projected together with their crews in opposed directions to cover two fields of fire, e.g. one above and one below the aircraft. In one arrangement, Figs. 2 and 4, turrets 1, 2 move upwardly and downwardly respectively from nested positions within a circular or oval section fuselage. The two cockpits are connected to move together and the lower may be weighted to provide the force for extension. Retraction may be by any mechanical or electrical means. Resilient means may be employed for increasing the speed of ejection. Each turret comprises a base frame such as 4 or 5, Fig. 4, with which are integral uprights or arcuate members on which can be fixed armour plating and transparent parts and in which are formed loopholes for the passage of firearms. The upper turret carries seats 6. If the arrangement be such that the two turrets enter partially within one another when retracted,. the lower gunners would be so placed that their heads come between the seats of the upper gunners. Frames 4, 5 are guided by rollers in slides 7. Driving means for retraction comprise endless chain systems 14, passing over fixed sprockets 10, 11, 12, 13 and connected to the frames at points in the upwardly and downwardly moving bights of the chains. The pulleys 10 are fast with meshed pinions 15, 16 of which 15 is fixed to a shaft 19 coupled to an electric motor shaft. The size of pinions 15, 16 is suitably chosen for the differing distances through which the turrets travel. The electric motor drives shaft 19 through a clutch or free-wheel device which is released for extension of the turrets. Fig. 6 shows a modification in which the two turrets are staggered. In this case a chain 22 connects the motor shaft 21 to shafts 19 and 20 carrying sprockets 10. Control of the electric motor and clutch is effected bv remote control means disposed at more than one point in the machine. The firearms may be drawn into the turrets before retraction or spaces such as 25, Fig. 4, provided therefor. The spaces between the turrets and the side walls of the body may be utilized for mounting laterally firing weapons.
