Abstract: 661,013. Ironing-presses. NEWBERY, S., and NEWBERY, Ltd., S. Oct. 6, 1949 [Oct. 6, 1948], No. 26080/48. Class 138 (ii). In a garment or lie press having an oscillable upper buck 4 adapted to co-operate alternately with each of a pair of lower bucks 5, 6, the upper buck is oscillable at relatively short radius, and each of the lower bucks is alternately displaceable to locate such in position adjacent the path of the buck preparatory to the pressing operation. A bringing together of a positioned lower buck and the upper, buck in order to press a garment is then effected by a further movement of the upper or lower buck towards the other. In the example shown the upper buck 4 is resiliently secured to a lever 10, 11 of bent or bell-crank form, pivotally secured to a radial arm 9 fixedly mounted on a shaft 8 which is rotatably mounted in bearings. The buck 4 may thus overlie each lower buck in turn and may be pressed against them by means of a toggle linkage 12, 13 the fixed pivot 14 of which is mounted on the arm 9 while the central pivot 15 of the toggle is connected to the piston rod 16 of a piston moving in a compressed air cylinder 17. The cylinder 17 is pivotally mounted at 18 on the arm 9 and is coupled to the usual air supply for operating a press. The radial arm 9 has at its lower end a double armed lever 20, 21 for operatively displacing the lower bucks 5, 6. This lever 20, 21 carries spaced crank-pins 22, 23, pivotally connected to cylinders 24, 25 or slideways in which lower buck actuating rods 26, 27 are guided, each rod having a stop 28, 29 engaged by its cylinder. Upon oscillation of the lever 20, 21 one of the rods 26 or 27 is moved upwardly. Compression springs 30, 31 arranged between the stops 28, 29 and the lower ends of the cylinders 24, 25 permit a certain amount of lost motion between the cylinders and rods to allow for any excess movement of the cranks 20, 21 over and above that required to cause the displacement of the bucks. The lower bucks are arranged longitudinally end to end and with the arm 9 in the mid-position the two bucks are slightly inclined from the horizontal, their inner ends being tilted upwardly by a few degrees. The bucks 5, 6 carry on their lower side a pair of lugs or flanges 39 to which are pivoted links 40, 44 which are also pivoted to a frame support 42. The lower pivots of 'the links are spaced further apart than the upper pivots so that the links diverge slightly towards their lower ends and afford a stable support for the bucks in the pressing position. The links 44 carry extensions 46 to which the rods 26, 27 are pivoted so that as the upper buck 4 moves from one pressing position to the other, one of the lower bucks is raised to pressing position while the other is lowered to a horizontal position in which a garment may be laid thereon. The radial arm 9 may be oscillated to and fro, through an angle of about 45 degrees, by means of a pneumatically-operated piston and cylinder but preferably by means of an eccentric 33 linked with the arm 9 by a coupling rod 34. The eccentric 33 is mounted on the output shaft 32 of a reduction gearbox 36 driven by belts 37 from a motor 38 having a suitable clutch. A table 2 mounted beneath the bucks has a bayed portion 3 for access to the bucks and it may also serve as a mounting for the press controls. In a modification (not shown), the radial arm 9 is replaced by a pair of parallel links by means of which the buck is brought alternately over one and the other of the lower bucks which are displaced into the pressing position by suitably modified mounting means. Specification 583,144 is referred to.
