363,757. Ironing-machines. SYRACUSE WASHING MACHINE CORPORATION, Syracuse, New York, U.S.A.- (Assignees of Ringer, L. ; 11, Grove Street, Union Springs, New York, U.S.A.) Oct. 17, 1930, No. 31121. Convention date, Nov. 29, 1929. [Class 138 (ii).] An ironing-machine of the type in which a roller coacts with a concave bed is provided with means whereby the bed may be (1) oscillated by power into and out of contact with the roller which during such oscillation may be either rotated intermittently or held stationary, (2) held stationary in contact with the continuously rotated roller, or (3) held stationary and out of contact with the roller which is also held stationary. In addition to the power oscillation of the bed independent manual means are provided for moving the bed out of contact with the roller. The bed 21, Fig. 3, is carried by arms 19 which are pivoted at 20 to a yoke 18 pivoted on a shaft 17. A member 28 pinned to the shaft 17 is normally latched at 31, 37 to the yoke 18 so that as the shaft 17 is oscillated the bed moves into and out of contact with the roller 6, the pressure being regulated by a spring 34. The yoke may be unlatched from the member 28 by rotating clockwise a bell-crank lever 42 provided with an operating handle 44 and further forward movement of the handle 44 effects the movement of 'the bed independent of the power means. A bifurcated arm 101, Fig. 8, secured to the shaft 17 is engaged by an eccentric 100 forming part of a clutch disc 59 which is provided with an aperture through which a key 60 on a shaft 55 can slide. The key engages a stationary cam 53, Fig. 10, whereby when the shaft 55 is rotated by the disc 59 and key 60 it is simultaneously axially reciprocated. A gear wheel 67, Fig. 8. which is geared to the ironing roller is rotatably mounted on the shaft 55 and is pressed by a spring 70 into clutching engagement with a constantly running worm wheel 62 when the key 60 engages the low part of the cam 53. When the shaft moves to the left a ring 74 secured thereto moves the gear wheel 67 out of engagement with the worm wheel. A toothed disc 65 is secured to the hub of the worm wheel 62 which is loose on the shaft 55. On a pin 86, Fig. 12, on the clutch disc 59 are pivoted a plate 89 and a dog 85 of substantially the same shape. The dog is formed with a tooth 87 which normally engages one of the teeth 88 of the toothed disc 65. Rotation of the worm wheel 62 therefore normally rotates the eccentric 100 to oscillate the ironing bed and axially reciprocates the shaft 55 to rotate the ironing roller intermittently. In order that the roller may be held stationary whilst the bed oscillates the rotation of the eccentric 100 is allowed to continue but the shaft 55 is held in the position wherein the gear wheel 67 is disengaged from the worm wheel 62 by the engagement of a rod 79, Fig. 9, in an annular groove 61 in the shaft. The rod is provided with a handle 80 and is held in its adjusted position by a spring 82. For stopping the oscillation of the bed there is provided a manually operated shaft 94, Fig. 12, which when rotated swings an arm 93 into the path of the plate 89 and when the plate engages therewith the tooth 87 will be withdrawn from the teeth of the disc 65 and the rotation of the eccentric, and consequently the rotation and axial movement of the shaft 55 will cease. The engagement of the plate 89 and arm 93 can occur at two points separated by 180‹ as shown. These positions correspond respectively to that in which the bed is in contact with the roller and the key 60 on the low part of the cam 53 so that the roller is continuously rotated by the engagement of gear wheel 67 with the worm wheel 62, and that in which the bed is out of contact with the roller and the key 60 on the high part of the cam so that the roller remains stationary. The movement of the arm 93 may alternatively be controlled by an electromagnet under the control of the operator.
