854,872. Ironing-machines. IRONRITE Inc. June 15, 1959 [June 18, 1958], No. 20482/59. Class 138 (2). In an ironing-machine, movement of a rotatable ironing roll 26 towards and away from a stationary shoe 24 is effected by a cam 74 which is rotatable through 180 degrees at a time by coupling it through a clutch 82 to a motor 38. The cam 74 is mounted on a shaft 52 and bears on a spring 76 rigid with a tube 30 supporting the roll 26. A spring 78 maintains the spring 76 and cam 74 in contact. The clutch 82 comprises a sun-gear 62 (Fig. 5), planet gears 64, a planet carrier 72 (Fig. 4), a ring gear 68 and a yoke assembly 84 for selectively restraining either the ring gear or the carrier. The yoke assembly 84 comprises two legs 92, 100 interconnected, by a spring 97, the leg 92 being fixed to and the leg 100 rotatable on a shaft 86. When a projection 94 on leg 92 engages in either of two notches 96 in the carrier 72, the carrier is prevented from rotating, and the roll is held in either shoe-engaging or retracted position. By raising a control pad 110 (Fig. 2) pivoted at 112 adjacent a feed board 116, the shaft 86 is rotated to withdraw projection 94 from notch 96 and move a tooth 104 on leg 100 into engagement with teeth 70 on the outer side of ring gear 68. The ring gear 68 is thus held stationary and the carrier 72 rotated by means of the sun and planet gears. When the carrier 72 has rotated through 180 degrees the cam 74 has moved the roll 26 from one position to the other and projection 94 engages the other notch 96 to stop further rotation of the carrier 72 and cam 74. The control pad 110 is connected to the shaft 86 through the linkage shown in Fig. 2. The roll 26 is driven by the motor 40 through gearing in a housing 32, a shaft 34 in the tube 30, and gearing 36 in one of two arms 28 supporting the roll. Figs. 7 to 14 (not shown) illustrate modified forms of control members.
