Abstract: 277,848. British-American Laundry Machinery Co., Ltd., (American Laundry Machinery Co.). Jan. 4, 1927. Ironing-presses.-In a press actuated wholly by power and provided with controls requiring operation by both hands of the operator, one control regulates the admission of fluid power to the piston operating the press-closing and power-applying means, and the other control couples and maintains the coupling between the press head lever and the upper toggle link forming part of the press-closing and power-applying means. A cap 18, pivoted at 20 to an extension of the head carrying lever 5 is provided with a depending extension 18b connected by a system of links and levers to a hand lever 26, a spring 30 tending to rotate the cap counterclockwise to keep it normally out of engagement with the upper end 17 of the toggle link 16 which slides in a block 19 swivelling about the pivot 20. The joint 13 of the toggle 16, 11 is linked to a. slotted lever 47 pivoted to the frame at 48. The lower toggle link is pivoted to an extension of a lever 9 pivoted at 10 to the base, the lever being rotated clockwise bv the fluid-actuated piston 35 through a pin-and-slot connection 42, 43 and restored by a spring 51. An integral bracket 9<b> on the lever 9 carries the roller 45 that coacts with the slot in lever 47. The first result of the depression of the lever 9 is to straighten the toggle links 11, 16, the elevation of the pivot 12 being as yet ineffective to produce pressure; further movement of the lever is without substantial effect on the toggle joint owing to the shape of the slot in lever 47, but raising the pivot 12 further to apply heavy pressure. Admission of the. operating fluid to the piston is controlled by a handle similar to the handle 26 but spaced therefrom. A device 87 is provided for cushioning the press head as it reaches the fully open position.
