371,486. Ironing-machines. EMERY, W. M., 336, North Owen Avenue, Lansdowne, Pennsylvania, U.S.A. Jan. 30, 1931, No. 3053. Convention date, Feb. 11, 1930. [Class 138 (ii).] In an ironing-machine comprising a concave bed and a coacting roller, the roller is supported by a yoke fitting closely thereto and, in an -overfeed machine wherein the roller is nearer than the bed to the operator, the yoke carrying the roller is supported underneath one end of the roller and the bed is supported centrally, whilst in an underfeed machine the bed is nearer to the operator and is supported underneath one end the yoke of the roller being supported centrally. Means are provided for swinging the roller into contact with the bed, the roller travelling' through less than 90‹, and other means are provided for adjusting the position of the rear member to maintain a normal pressure. As shown in Fig. 6, the bed 10 of an overfeed machine is carried centrally by a support 9 at the rear left-hand corner of a baseplate 1 and the yoke 3 of the roller 6 is supported at one end by a member 2 at the front right-hand corner of the baseplate. Eccentrics 16, 17, Fig. 1, are pivoted at 18, 20 in the arms 4, 5 of the yoke and shafts 15, 15<1> carrying the roller through spiders 7, 8 are supported in the eccentrics and their projecting ends can move along slots in the arms 4, 5. , The motor 26, which is housed in a ventilated casing 22 secured inside the roller by spiders 23, 24, 25 which also carry the bearings for the other ends of the shafts 15, 151, drives a clutch disc 47, loose on the shaft 15<1>, through the reduction gear shown. When clutch pins 50, 51 are projected through the spider 8 into the path of the teeth 48 of the disc 47 the roller is rotated unless such rotation is prevented by the engagement, with teeth 56 projecting radially from the outer face of the spider 8, cf a pawl 57 which is secured to a plate 59, Fig. 2, pivoted about a transverse shaft 62 carried in bearings 70, 71 in the arm 5. When the rotation of the roller is prevented, the roller and its shalts 15, 15<1> swing about the pivots of the eccentrics 16, 17, Fig. 1, so that the roller is moved into or out of contact with the concave bed. The pins 50, 51 are forced into engagement with the disc 47 against a spring 55 by means of a disc 52 moved by a cam 64 on the shaft 62 which is rotated by a device 82, Fig. 6, operated by the knee of the operator or by means of a treadle. The pawl 57 is normally pressed by a spring 65, Fig. 2, into engagement with the radial teeth 56 and is automatically withdrawn as the roller contacts with the bed by the engagement, with a projection 69 on the opposite face of the plate 59, of an arm 68 carried by the eccentric 17, Fig. 1. In a modification, Fig. 11, the shaft 151 is formed with gear teeth 106 which engage a rack 107 secured to the inner face of one of the arms 104 of the roller yoke. When rotation of the roller is pievented by the engagement of the pawl 57<1> with the radial teeth of the spider 8 the shaft 15<1> rotates and travels up the rack 107 and along the slot 105 in the arm 104 thereby moving the roller into contcat with the bed. The pawl 57<1> is automatically released from engagement with the radial teeth of the spider 8 by the engagement, with a projection on the plate 59<1> corresponding to the projection 69, Fig 2, of an arm 112 carried by the shaft 15<1> the arm contacting with the projection as the shaft 15<1> rises and rotates in the slot 105 In another modification, Fig. 29, the arm 4 of the roller yoke is formed with transverse guide tracks 152, 153 and the shaft 15 is secured to a link 154 knuckle-jointed at 158 to another link 160 which is pivoted at 162 to the arm 4. The shaft 15 is thereby held against rotation, and when rotation of the roller is prevented the roller is swung into contact with the shoe, the head 155 of the clamp securing the shaft 15 to the link 154 being guided between the members 152, 153. The shape of the upper track 152 permits the links to assume the angular position shown in dotted lines when the roller is away from the shoe. The means for adjusting the support of the rear member which may be the support 9, Fig. 6, of the bed of an overfeed machine or the support 2<1>, Fig. 22, of the roller of an underfeed machine, comprise a pivotal mounting 90, 91 for the support in the rear left-hand corner of the base 1. The cranked end 102, Fig. 25, of a lever 98 having a cam 99 projects through a slot 101, Fig. 16, in the base and the lever is pivoted about a bolt 93, Fig. 22, adjustably secured in a lug 92 in the support 2<1>, the cam 99 engaging with the underface 95 of an overhanging portion of the base through which the bolt 93 loosely passes. The base slopes downwardly from back to front so as to provide the maximum clearance between its upper face and the underface of the front ironing member. An aperture 113, Fig. 16, is provided in the base so that the apparatus when not in use may be hung on a hook 114 on the wall, and a handle may be secured to one of the arms of the roller yoke to facilitate transport of the machine. The bed is provided with a rounded end to facilitate the placing of garment sleeves thereover and with a central core which is electrically heated and is light in weight. The rear face of the bed is covered with heatinsulating material, the front face is recessed and the recess is filled with this material also and a thin face-plate of sheet steel is secured thereto.
