IPC: B21K1/70
Filed: 1949-12-08
Abstract: 682,454. Forging nuts. SECURIT'S E.D.L.C. Dec. 8, 1949 [Dec. 10, 1948], No. 31589/49. Classes 83 (ii) and 83 (iv). In a method of manufacturing locking nuts of the type comprising an inner element 1, Fig. 1, and an outer element 2 which fit one within the other without being capable of relative rotation, a bevelled annular member 14, Fig. 8, is first formed from a flat blank and is adapted to serve as the starting element for the manufacture of either the inner or outer element, and the inner or outer element is then struck from the member 14 in a separate stamping operation including only a single pressing stroke, the inner element being subsequently threaded and slit longitudinally. To form the annulus 14 the flat blank is placed in a die 6, Fig. 6, on an anvil 7 having a slightly elevated surface portion 10 with an inclined edge, and pressed by a punch 8 to produce a hollowed block 9. This is placed in a die 12, Fig. 7, and punched through by a punch 13 to complete the annulus 14, which has a substantial upper bevel and a narrow lower bevel 11<SP>1</SP>. For stamping the outer element 2 the member 14 is placed in a die 16, Fig. 9, having internally the desired outside shape of the element 2, and pressed by a punch 17, the outside shape of which has frusto-conical, polygonal, and cylindrical portions. Extruding.-The diameter of the cylindrical portion is slightly less than that of the guideway through the die 16 to form a clearance space 18 into which metal is forced during the striking operation to produce a flange 4. For obtaining an inner element 1, there are employed a die 19, Fig. 10, having a polygonal and a frusto-conical portion and a smooth cylindrical punch 20. The bore of the element thus obtained is tapped and then slit longitudinally. Specification 502,477 is referred to.

Title: Improvements in coupling devices for railway vehicles
Inventor: CHECKLEY PETER EDWARD
IPC: B61G7/08
Filed: 1957-10-15
Abstract: 876,173. Couplings and draw gear for railway vehicles. DOWTY HYDRAULIC UNITS Ltd. Sept. 30, 1958 [Oct. 15, 1957; Jan. 10, 1958], Nos. 32221/57 and 1050/58. Class 103(5). A convertible automatic to non-automatic coupling and draw gear for a railway vehicle equipped with normal side buffers, comprises a coupler head, Fig. 2, coupling by inclined swing and mounted by means of a universal joint 14 on a longitudinally movable draw bar 13, a pre-loaded draw spring assembly 41, a pivot pin 19 bolted to the head and provided at its other end with a ball 57, Fig. 5, bonded through rubber 62 to a cylindrical housing 58 rotatable in a ring shaped head 49, and a spring assembly 42, Figs. 2, 3, having a collar 45 pivoted on trunnions 43 to underframe brackets 44, and a cylinder 46 slidable within the collar and enclosing one end of a pre-loaded spring 50, the assembly exerting a moment upon the pin 19 about the universal joint 14 to support the weight of the coupler head and also provide resilient restraint against rearward movement of the draw bar. The cylinder 46 has a stop flange 39, a fixed bush 47 against which the spring 50 abuts, and a rod 48 integral with the ring head 49, the rod being provided with an adjustable stop nut 52 which may abut and slide a flanged bush 51 within a bridge piece 53 fixed by tie rods 54 to the collar 45. In operation the rubber bonded ball joint 57 acts as a torsion spring and centralises the coupler head in a horizontal plane, and a downward flattened extension 77 of the pivot pin 19 extends into a slot 76 in an extension 75 of the ball housing 58 to limit deflection of the coupler head to 15 degrees either side of the vehicle longitudinal axis. If the head 49 is displaced forwardly against spring load, the cylinder 46 and the bush 47 are held by the stop 39 while the nut 52 and the bearing bush 51 displace the rear end of the spring 50. If the head 49 is displaced rearwardly, the side buffers absorb the buffing load and the flanged bearing 51 rests against the bridge 53 while the forward end of the spring 50 is displaced by the bush 47, cylinder 46 and head 49 moving together. When the automatic coupler head is in use a spring pressed hand operated locking pin 66 engages a slot 63 in the rotatable housing 58 rubber bonded to the pivot pin 19, 'but by disengaging the pin 66 the coupler head may be swung laterally aside to bring a coupling hook integral with the head into line with the draw bar 13. The pin 66 may then be allowed to lock into the alternative slot 64 in the. housing 58. In a modification, Fig. 7 (not shown) a smaller weight supporting spring is provided around the rod 48, and a separate spring aligned with the draw bar is used for extending the draw bar. Specifications 843,365 and 876,174 are referred to.

Title: Improvements relating to gas-cushion vehicles
Inventor: COCKERELL CHRISTOPHER SYDNEY
IPC: B60V1/16
Filed: 1967-07-13
Abstract: 1,236,571. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. 12 July, 1968 [13 July, 1967], No. 32349/67. Heading B7K. An air cushion vehicle has a flexible skirt comprising an upper part 19 made of a flexible impermeable sheet, and a lower part 18 which is preferably of the type disclosed in Specification 1,043,351 and depends from the upper part except near the bow of the vehicle where it depends directly from the body of the vehicle, the members 18 of the lower part adjacent the sides of the vehicle being attached to variable length ties thereby to displace at least a part of the lower part of the skirt relative to the body of the vehicle and provide an adjustment of the centre of pressure position. The two parts of the skirt contain an air cushion 17, air being supplied to the cushion by a fan 14 which is driven by a motor 15 and draws air through a duct 13. The vehicle is propelled by a power unit P. In Fig. 5, the ties 22 attached to the members 18 pass into the body of the vehicle via air tight seals 24 and are wound on to shafts 23 which extend parallel to the fore-aft axis of the vehicle. Each shaft 23 tapers towards its ends so that when a shaft 23 is rotated, the length of a tie wound around the centre of the shaft varies more than the length of a tie nearer an end of the shaft, and there is thus a differential movement of the skirt members 18. Each shaft 23 has shallow grooves to prevent the ties moving sideways along the taper of the shaft. When a shaft 23 rotates, the area between planes A-A of Fig. 5 which contains the effective lifting cushion 17 is displaced laterally to alter the trim of the vehicle. The shafts may be rotated by equal amounts in the same sense so as to move the whole cushion whilst retaining a constant cushion area, or may be moved by unequal amounts in which case the cushion area changes. A similar arrangement may be used with a shaft at the stem of the vehicle transverse the fore-aft axis to differentially move the lower part of the skirt at the stern of the vehicle and thus provide pitch control. The shafts are driven by electric motors which may be coupled to attitude sensing switches, e.g. mercury switches, to provide automatic attitude control. Instead of tapered shafts, cylindrical shafts having circumferential grooves may be used, the grooves being deeper near the ends of the shafts.

Abstract: 945,419. Wrapping machines. CONTINENTAL CAN CO. Inc. Sept. 8, 1961 [Sept. 21, 1960], No. 32362/61. Heading B8C. Apparatus for applying a wrap-around wrapper blank to articles such as containers said blanks having two side panels hingedly connected to an intermediate panel and closure panels hingedly connected one to each of the side panels, comprises means for folding and closing the blank about a row or rows of articles and reciprocable tightening members engageable with the side panels of the wrapper to apply lateral forces thereto during the closing of the wrapper blank. Bottles 10 to be packaged are delivered into the machine along support plates 12 (Fig. 1) and wrapper blanks 11 with openings 16 to receive the bottle necks 17 are placed upon them and side panels 18 and 19 folded down as described in Specification 885,915. The bottles are advanced along by means of pushers 13 pivotally attached to drive chains 14 driven by sprockets 31. While travelling along the support plate the closing panels 20 and 21 are initiated upwards by means of bars 32 and 33. On reaching the tapered portion 34 of the support plate the tightening means are brought into operation. Each tightener 35 comprises a rod 42 having a head 138 at one end and a roller 43 at the other the tightener being mounted in a support 36 attached to a drive chain 37, said tightener travelling parallel to the bottles and being reciprocated by cam means 44. As the drive chain 37 moves over sprockets 38, 39 the roller 43 engages the ramp portion 45 of the cam and as it travels along this portion the head 138 is forced towards the support plate. When the roller reaches the straight part of the cam the head 138 is pressing against the side panel of the wrapper thus initiating the tightening operation, said chain drives 14 and 37 being synchronized to permit this. The tightening continues while the roller proceeds along the straight portion when the closure of the wrapper blank is completed as described in Specification 871,045. On reaching the ramp portion 46 the roller rides up it and the spring 47 causes the tightener head 138 to move away from the package and the tightening ceases. The package is then free to travel through the exit portion of the machine.
