Abstract: 332,702. Baker Perkins, Ltd., and Tanqueray, D. Y. B. June 19, 1929. Ironing processes; work-supports in ironing- presses; shirt clamps and holders. - Garments, particularly shirts, are supported in such a way that a blast of drying air is blown through them so as to stretch and balloon them during ironing. The machine comprises a stationary hollow pedestal 11, Fig. 3, and a rotary hollow member 20 having a pair of hollow arms 22, Fig. 2, curved in a horizontal plane to U-shape and a pair of smaller arms 43, Fig. 3, bent at right-angles in a vertical plane as shown, projecting therefrom. Two grids are formed in each arm 22 over which pads 23, 47, Fig. 2, are placed and the end of each arm 43 is closed by a grid 45, Fig. 3, over which a pad 44 is placed. Each pad 23 supports the bosom of a shirt and the pads 44, 47 support the cuffs whilst the tail portion of each shirt is stretched by a pivoted member 42, Fig. 1, and is fastened by clips 41 and a special clip 40, Figs. 1 and 2, to a member 39 on each arm 22. The member 20 is rotated so that one of the groups of supports 23, 44, 47, 39 is positioned beneath a group of three irons .48. Fig. 3, carried by the head 17 of the stationary pedestal. The irons are pressed down upon the bosom and cuffs of the shirt and are raised therefrom by fluid pressure, the control valve 52, Fig. 1, in the supply pipe of which is operated by movement of the clip 40 of that group of work supports which is not under the irons. Movement of this clip to unfastening position operates the valve to depress the irons and the same movement mechanically locks the rotary member 20 by engaging a plunger 60 in an aperture 61 in the pedestal. After the clip 40 has been unfastened the remaining clips 41 of the support not under the irons are unfastened and the shirt is removed. Another shirt is then positioned on this group of supports, and the clips 41, and finally the clip 40, fastened. The fastening of the clip 40 unlocks the rotary member and raises the irons from the shirt carried by the group of supports positioned thereunder. The member 20 is then rotated so that the shirt just positioned is swung beneath the irons whilst the one just ironed is swung away therefrom. Release of the clip 40 of the latter then effects depression of the irons on the shirt just swung thereunder. A fan 14, Fig. 3, which may be operated continuously or which may be switched on by the opening of the clip 40, is arranged in the head of the stationary pedestal for drawing air over a heater 13 and forcing it through an aperture 18 in the pedestal into the arms 22, 43 of the work support that is beneath the irons from which it passes through the grids and also through apertures 46, Figs. 1 and 3, and, if desired, also through the tail support 39 to balloon the shirt &c. The member 20 is rotated by means of a fluid pressure operated rack which engages a pinion thereon, the supply of fluid being controlled by a valve 57 operated by a pedal 59. The part of the apparatus in which the ballooning is effected may be screened off as by flap or revolving paddle doors so that the hot air is kept in a substantially closed circuit. To steady the arms 22 a pin 62, Fig. 5, is carried thereon which engages a recessed stud 63 on the fixed head during the ironing. The neckband clamp 25 comprises an arcuate member 26, Fig. 10, and sliding members 27, 28 simultaneously operated by a finger piece 32 carried by the member 28. The member 28 slides along a fixed pin 33 and is connected by a pin a slot connection 35 to the members 27 which are provided with inclined pins 29 which slide through inclined sleeves 30 carried by the member 26. The sliding members are locked by the engagement of a spring pressed leaf 37, carried by the member 28, with the pin 33.
