Abstract: 1,152,639. Garment pressing machines. H. D. FORSE. 3 Jan., 1968 [23 Jan., 1967], No. 462/68. Heading D1A. A garment pressing machine comprises a horizontal frame 32 on which are mounted two vertical bucks 34, 36 movable respectively between first and second and between third and fourth positions, the second and fourth positions being substantially the same and each buck moving in an arcuate path 108, 102 in a plane 110, 104 the planes being at an angle to the horizontal and to one another, the paths intersecting in spaced points 120, 122 on a third plane perpendicular to the horizontal. Frame 32 is mounted in a cabinet 33 and has a base portion 42 including two bearing plates 50, 52 inclined at a small angle b to the longitudinal axis of portion 42 and at a larger angle a to the horizontal. Bucks 34, 36, to receive shirts 35, are mounted on plates 98, 76 pivoted on pairs of arms 78, 80 and 56, 58 pivoted respectively to plates 50, 52 so as to move in paths 108, 102, the intersections 120, 122 of these paths being at the dressing and pressing stations respectively. Alternatively, a separate plate may be provided for each arm or each buck may be carried on a single arm. Pairs of levers 124, 126; 130, 132 rigidly connected respectively to arms 56, 58', 78, 80 are connected by links 128, 134 connected to the piston rods 150; 152 of cylinders 136; 138 pivoted to base 42. Rods 150, 152 are extended alternatively to move one buck 36, 34 to the dressing position a linkage being provided to ensure simultaneous movement of bucks 34, 36. Alternatively, Fig. 16, A-frames 184 secured to plates 50, 52 have their upper ends connected by over-centre springs to links 128, 134. The pressing station comprises a frame made up of two side portions and a rear portion 210. Pivot support members 216, 218 are secured to frame 210 and to side frame members 180, 182 by plate members 222, 224 whose upper and lower ends are connected by tension members 226, 228. Pivot bracket members 230, 232 are secured to the forward ends of members 216, 218 and are connected by members 234, (236), Fig. 17 (not shown), to frame element 144. Two parallel sets of aligned openings 240, 244 and 242, 246 in plates 230, 232 and a transverse member 238 receive pivots 262 which carry lever assemblies 250, 252 whose lower ends are connected to a piston 276 and cylinder 274 and the assemblies being urged apart by springs 278, 280, an equalising arrangement being provided for the movement of assemblies 250, 252. The pressing heads 40, 38 are pivoted to the uppper ends of assemblies 250, 252 so as to remain upright. Heads 38, 40, which may be steam heated, having their facing surfaces shaped to fit bucks 34, 36 including a recess to receive collar supports 324 on the bucks 34, 36. Buck 36, being identical with buck 34, comprises forward and rear sides 352 354 formed by pairs of spaced metal sheets 356, 358 and 360, 362 mounted on base 350 forming closed chambers 364, 366 there-between to which steam is fed. Between sides 352, 354, which may be covered with padding, is a space 368 into which wings 382, 384 are retractable wick are pivoted on the base 350 and actuated by the piston rods 410, 412 of cylinders 406, 408. Flexible members 414, 416 carried on wings 382, 384 extend into the shirt sleeves. The shirt tail is clamped by clamp 418 secured to a lever 420 which is pivoted in an opening 422 in member 350 and is actuated by the piston rod 430 of cylinder 426. Control valves 438, 436 are mounted on plate 440 and are connected by rods 442, 444 to links 450, 452 with knees 447, 449 to which are pivoted arms 446, 448. Arms 446, 448 are each pivoted to a member 451 pivoted to plate 440 and connected by rod 462 to a spring 464 arid to one end of a lever carrying a pad 458 to be engaged by the base 350 of the buck in its pressing position. When pad 158 is engeged by a member 350 it is moved against the action of spring 464 and valves 438, 436 are actuated until arm 448 is engaged by the piston rod 476 of a pneumatic timing cylinder 474 and arm 446 is engaged by a lever 480 operated by a roller 494 carried on a lever 492 mounted on a member 486 secured to lever assembly 250 when the latter moves outwardly. Manual pivoting of member 451 by means of rod 502 causes opening of heads 38, 40. A lever 510 operated by pedals 512, 514 operates rod 526 connected to lever 518 to control valve 522 which actuates the buck tail clamp and wings. Valve 522 is also actuated by cam plate 524 engaging roller 520 when link 128 moves longitudinally. Operation is initiated by buttons 528, 529 carried on spring biassed push rods 537, mounted on either side of a partition so that both hands must be used, which engage a lever 533 pivoted to a lever 530 which controls a valve 538 and cannot be operated during the cycle. Actuation of valve 538 causes the reversing movement of bucks 34, 36 and heads 38, 40 are subsequently closed.
